The Go project reports:
net/http (through net/textproto) used to accept and normalize invalid HTTP/1.1 headers with a space before the colon, in violation of RFC 7230. If a Go server is used behind a reverse proxy that accepts and forwards but doesn't normalize such invalid headers, the reverse proxy and the server can interpret the headers differently. This can lead to filter bypasses or request smuggling, the latter if requests from separate clients are multiplexed onto the same connection by the proxy. Such invalid headers are now rejected by Go servers, and passed without normalization to Go client applications.

Janos Follath reports:
Mbed TLS does not have a constant-time/constant-trace arithmetic library and uses blinding to protect against side channel attacks.
In the ECDSA signature routine previous Mbed TLS versions used the same RNG object for generating the ephemeral key pair and for generating the blinding values. The deterministic ECDSA function reused this by passing the RNG object created from the private key and the message to be signed as prescribed by RFC 6979. This meant that the same RNG object was used whenever the same message was signed, rendering the blinding ineffective.
If the victim can be tricked to sign the same message repeatedly, the private key may be recoverable through side channels.
Jon Siwek of Corelight reports:
This is a security patch release to address a potential Denial of Service vulnerability:
- The NTLM analyzer did not properly handle AV Pair sequences that were either empty or unterminated, resulting in invalid memory access or heap buffer over-read. The NTLM analyzer is enabled by default and used in the analysis of SMB, DCE/RPC, and GSSAPI protocols.
expat project reports:
XML names with multiple colons could end up in the wrong namespace, and take a high amount of RAM and CPU resources while processing, opening the door to use for denial-of-service attacks
curl security problems:
CVE-2019-5481: FTP-KRB double-free
libcurl can be told to use kerberos over FTP to a server, as set with the CURLOPT_KRBLEVEL option.
During such kerberos FTP data transfer, the server sends data to curl in blocks with the 32 bit size of each block first and then that amount of data immediately following.
A malicious or just broken server can claim to send a very large block and if by doing that it makes curl's subsequent call to realloc() to fail, curl would then misbehave in the exit path and double-free the memory.
In practical terms, an up to 4 GB memory area may very well be fine to allocate on a modern 64 bit system but on 32 bit systems it will fail.
Kerberos FTP is a rarely used protocol with curl. Also, Kerberos authentication is usually only attempted and used with servers that the client has a previous association with.
CVE-2019-5482: TFTP small blocksize heap buffer overflow
libcurl contains a heap buffer overflow in the function (tftp_receive_packet()) that receives data from a TFTP server. It can call recvfrom() with the default size for the buffer rather than with the size that was used to allocate it. Thus, the content that might overwrite the heap memory is controlled by the server.
This flaw is only triggered if the TFTP server sends an OACK without the BLKSIZE option, when a BLKSIZE smaller than 512 bytes was requested by the TFTP client. OACK is a TFTP extension and is not used by all TFTP servers.
Users choosing a smaller block size than default should be rare as the primary use case for changing the size is to make it larger.
It is rare for users to use TFTP across the Internet. It is most commonly used within local networks. TFTP as a protocol is always inherently insecure.
This issue was introduced by the add of the TFTP BLKSIZE option handling. It was previously incompletely fixed by an almost identical issue called CVE-2019-5436.
The OpenSSL project reports:
ECDSA remote timing attack (CVE-2019-1547) [Low]

Adobe reports:
- This update resolves a same origin method execution vulnerability that could lead to arbitrary code execution (CVE-2019-8069).
- This update resolves a use-after-free vulnerability that could lead to arbitrary code execution (CVE-2019-8070).
A use-after-free in onig_new_deluxe() in regext.c in Oniguruma 6.9.2 allows attackers to potentially cause information disclosure, denial of service, or possibly code execution by providing a crafted regular expression. The attacker provides a pair of a regex pattern and a string, with a multi-byte encoding that gets handled by onig_new_deluxe().
A NULL Pointer Dereference in match_at() in regexec.c in Oniguruma 6.9.2 allows attackers to potentially cause denial of service by providing a crafted regular expression.
Oniguruma issues often affect Ruby, as well as common optional libraries for PHP and Rust.

In addition to the above changes, we are also updating jQuery on older versions of WordPress. This change was added in 5.2.1 and is now being brought to older versions.
Exim developers report:
If your Exim server accepts TLS connections, it is vulnerable. This does not depend on the TLS libray, so both, GnuTLS and OpenSSL are affected.
The vulnerability is exploitable by sending a SNI ending in a backslash-null sequence during the initial TLS handshake. The exploit exists as a POC. For more details see the document qualys.mbx
The Asterisk project reports:
When audio frames are given to the audio transcoding support in Asterisk the number of samples are examined and as part of this a message is output to indicate that no samples are present. A change was done to suppress this message for a particular scenario in which the message was not relevant. This change assumed that information about the origin of a frame will always exist when in reality it may not.
This issue presented itself when an RTP packet containing no audio (and thus no samples) was received. In a particular transcoding scenario this audio frame would get turned into a frame with no origin information. If this new frame was then given to the audio transcoding support a crash would occur as no samples and no origin information would be present. The transcoding scenario requires the genericplc option to be set to enabled (the default) and a transcoding path from the source format into signed linear and then from signed linear into another format.
Note that there may be other scenarios that have not been found which can cause an audio frame with no origin to be given to the audio transcoding support and thus cause a crash.
The Asterisk project reports:
When Asterisk sends a re-invite initiating T.38 faxing, and the endpoint responds with a declined media stream a crash will then occur in Asterisk.

Ruby news:
There are multiple vulnerabilities about Cross-Site Scripting (XSS) in jQuery shipped with RDoc which bundled in Ruby. All Ruby users are recommended to update Ruby to the latest release which includes the fixed version of RDoc.
The following vulnerabilities have been reported.
CVE-2012-6708
CVE-2015-9251
Aki Tuomi reports:
Vulnerability Details: IMAP and ManageSieve protocol parsers do not properly handle NUL byte when scanning data in quoted strings, leading to out of bounds heap memory writes. Risk: This vulnerability allows for out-of-bounds writes to objects stored on the heap up to 8096 bytes in pre-login phase, and 65536 bytes post-login phase, allowing sufficiently skilled attacker to perform complicated attacks that can lead to leaking private information or remote code execution. Abuse of this bug is very difficult to observe, as it does not necessarily cause a crash. Attempts to abuse this bug are not directly evident from logs.

Jonathon Loomey of Netflix reports:
HTTP/2 implementations do not robustly handle abnormal traffic and resource exhaustion
Recently, a series of DoS attack vulnerabilities have been reported on a broad range of HTTP/2 stacks. Among the vulnerabilities, H2O is exposed to the following:
- CVE-2019-9512 "Ping Flood": The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
- CVE-2019-9514 "Reset Flood": The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
- CVE-2019-9515 "Settings Flood": The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.

Micah Snyder reports:
- An out of bounds write was possible within ClamAV&s NSIS bzip2 library when attempting decompression in cases where the number of selectors exceeded the max limit set by the library (CVE-2019-12900). The issue has been resolved by respecting that limit.
- The zip bomb vulnerability mitigated in 0.101.3 has been assigned the CVE identifier CVE-2019-12625. Unfortunately, a workaround for the zip-bomb mitigation was immediately identified. To remediate the zip-bomb scan time issue, a scan time limit has been introduced in 0.101.4. This limit now resolves ClamAV's vulnerability to CVE-2019-12625.
Node.js reports:
Node.js, as well as many other implementations of HTTP/2, have been found vulnerable to Denial of Service attacks. See https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md for more information.
Updates are now available for all active Node.js release lines, including Linux ARMv6 builds for Node.js 8.x (which had been delayed).
We recommend that all Node.js users upgrade to a version listed below as soon as possible.
Vulnerabilities Fixed
Impact: All versions of Node.js 8 (LTS "Carbon"), Node.js 10 (LTS "Dubnium"), and Node.js 12 (Current) are vulnerable to the following:
- CVE-2019-9511 "Data Dribble": The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
- CVE-2019-9512 "Ping Flood": The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
- CVE-2019-9513 "Resource Loop": The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU, potentially leading to a denial of service.
- CVE-2019-9514 "Reset Flood": The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
- CVE-2019-9515 "Settings Flood": The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
- CVE-2019-9516 "0-Length Headers Leak": The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory, potentially leading to a denial of service.
- CVE-2019-9517 "Internal Data Buffering": The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
- CVE-2019-9518 "Empty Frames Flood": The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU, potentially leading to a denial of service. (Discovered by Piotr Sikora of Google)

Joe Cooper reports:
I've rolled out Webmin version 1.930 and Usermin version 1.780 for all repositories. This release includes several security fixes, including one potentially serious one caused by malicious code inserted into Webmin and Usermin at some point on our build infrastructure. We're still investigating how and when, but the exploitable code has never existed in our github repositories, so we've rebuilt from git source on new infrastructure (and checked to be sure the result does not contain the malicious code).
I don't have a changelog for these releases yet, but I wanted to announce them immediately due to the severity of this issue. To exploit the malicious code, your Webmin installation must have Webmin -> Webmin Configuration -> Authentication -> Password expiry policy set to Prompt users with expired passwords to enter a new one. This option is not set by default, but if it is set, it allows remote code execution.
This release addresses CVE-2019-15107, which was disclosed earlier today. It also addresses a handful of XSS issues that we were notified about, and a bounty was awarded to the researcher (a different one) who found them.
The Gitea Team reports:
This release contains two security fixes, so we highly recommend updating.
nvd.nist.gov reports
X.Org xdm 1.1.10, 1.1.11, and possibly other versions, when performing authentication using certain implementations of the crypt API function that can return NULL, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) by attempting to log into an account whose password field contains invalid characters, as demonstrated using the crypt function from glibc 2.17 and later with (1) the "!" character in the salt portion of a password field or (2) a password that has been encrypted using DES or MD5 in FIPS-140 mode.

nghttp2 GitHub releases:
This release fixes CVE-2019-9511 "Data Dribble" and CVE-2019-9513 "Resource Loop" vulnerability in nghttpx and nghttpd. Specially crafted HTTP/2 frames cause Denial of Service by consuming CPU time. Check out https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md for details. For nghttpx, additionally limiting inbound traffic by --read-rate and --read-burst options is quite effective against this kind of attack.
CVE-2019-9511 "Data Dribble": The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
CVE-2019-9513 "Ping Flood": The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.

Nokogiri GitHub release:
A command injection vulnerability in Nokogiri v1.10.3 and earlier allows commands to be executed in a subprocess by Ruby's Kernel.open method. Processes are vulnerable only if the undocumented method Nokogiri::CSS::Tokenizer#load_file is being passed untrusted user input.
This vulnerability appears in code generated by the Rexical gem versions v1.0.6 and earlier. Rexical is used by Nokogiri to generate lexical scanner code for parsing CSS queries. The underlying vulnerability was addressed in Rexical v1.0.7 and Nokogiri upgraded to this version of Rexical in Nokogiri v1.10.4.

The KDE Community has released a security announcement:
The syntax Key[$e]=$(shell command) in *.desktop files, .directory files, and configuration files (typically found in ~/.config) was an intentional feature of KConfig, to allow flexible configuration. This could however be abused by malicious people to make the users install such files and get code executed even without intentional action by the user.
Jesse Smith (upstream author of the doas program) reported:
Previous versions of "doas" transferred most environment variables, such as USER, HOME, and PATH from the original user to the target user. Passing these variables could cause files in the wrong path or home directory to be read (or written to), which resulted in potential security problems.
Many thanks to Sander Bos for reporting this issue and explaining how it can be exploited.
Jon Siwek of Corelight reports:
This is a security patch release to address potential Denial of Service vulnerabilities:
- Null pointer dereference in the RPC analysis code. RPC analyzers (e.g. MOUNT or NFS) are not enabled in the default configuration.
- Signed integer overflow in BinPAC-generated parser code. The result of this is Undefined Behavior with respect to the array bounds checking conditions that BinPAC generates, so it's unpredictable what an optimizing compiler may actually do under the assumption that signed integer overlows should never happen. The specific symptom which lead to finding this issue was with the PE analyzer causing out-of-memory crashes due to large allocations that were otherwise prevented when the array bounds checking logic was changed to prevent any possible signed integer overlow.

Given a suitable `SECURITY DEFINER` function, an attacker can execute arbitrary SQL under the identity of the function owner. An attack requires `EXECUTE` permission on the function, which must itself contain a function call having inexact argument type match. For example, `length('foo'::varchar)` and `length('foo')` are inexact, while `length('foo'::text)` is exact. As part of exploiting this vulnerability, the attacker uses `CREATE DOMAIN` to create a type in a `pg_temp` schema. The attack pattern and fix are similar to that for CVE-2007-2138.
Writing `SECURITY DEFINER` functions continues to require following the considerations noted in the documentation:
https://www.postgresql.org/docs/devel/sql-createfunction.html#SQL-CREATEFUNCTION-SECURITY
Versions Affected: 11
In a database containing hypothetical, user-defined hash equality operators, an attacker could read arbitrary bytes of server memory. For an attack to become possible, a superuser would need to create unusual operators. It is possible for operators not purpose-crafted for attack to have the properties that enable an attack, but we are not aware of specific examples.
Django release notes:
CVE-2019-14232: Denial-of-service possibility in django.utils.text.Truncator
If django.utils.text.Truncator's chars() and words() methods were passed the html=True argument, they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which were thus vulnerable
The regular expressions used by Truncator have been simplified in order to avoid potential backtracking issues. As a consequence, trailing punctuation may now at times be included in the truncated output.
CVE-2019-14233: Denial-of-service possibility in strip_tags()
Due to the behavior of the underlying HTMLParser, django.utils.html.strip_tags() would be extremely slow to evaluate certain inputs containing large sequences of nested incomplete HTML entities. The strip_tags() method is used to implement the corresponding striptags template filter, which was thus also vulnerable.
strip_tags() now avoids recursive calls to HTMLParser when progress removing tags, but necessarily incomplete HTML entities, stops being made.
Remember that absolutely NO guarantee is provided about the results of strip_tags() being HTML safe. So NEVER mark safe the result of a strip_tags() call without escaping it first, for example with django.utils.html.escape().
CVE-2019-14234: SQL injection possibility in key and index lookups for JSONField/HStoreField
Key and index lookups for JSONField and key lookups for HStoreField were subject to SQL injection, using a suitably crafted dictionary, with dictionary expansion, as the **kwargs passed to QuerySet.filter().
CVE-2019-14235: Potential memory exhaustion in django.utils.encoding.uri_to_iri()
If passed certain inputs, django.utils.encoding.uri_to_iri() could lead to significant memory usage due to excessive recursion when re-percent-encoding invalid UTF-8 octet sequences.
uri_to_iri() now avoids recursion when re-percent-encoding invalid UTF-8 octet sequences.
The Gitea Team reports:
This version of Gitea contains security fixes that could not be backported to 1.8. For this reason, we strongly recommend updating.
If a process attempts to transmit rights over a UNIX-domain socket and an error causes the attempt to fail, references acquired on the rights are not released and are leaked. This bug can be used to cause the reference counter to wrap around and free the corresponding file structure.
A local user can exploit the bug to gain root privileges or escape from a jail.
The pci_xhci_device_doorbell() function does not validate the 'epid' and 'streamid' provided by the guest, leading to an out-of-bounds read.
A misbehaving bhyve guest could crash the system or access memory that it should not be able to.
System calls operating on file descriptors obtain a reference to relevant struct file which due to a programming error was not always put back, which in turn could be used to overflow the counter of affected struct file.
A local user can use this flaw to obtain access to files, directories, sockets etc. opened by processes owned by other users. If obtained struct file represents a directory from outside of user's jail, it can be used to access files outside of the jail. If the user in question is a jailed root they can obtain root privileges on the host system.
Due to insufficient initialization of memory copied to userland in the components listed above small amounts of kernel memory may be disclosed to userland processes.
A user who can invoke 32-bit FreeBSD ioctls may be able to read the contents of small portions of kernel memory.
Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way; for example, a terminal buffer might include a user-entered password.
The code which handles a close(2) of a descriptor created by posix_openpt(2) fails to undo the configuration which causes SIGIO to be raised. This bug can lead to a write-after-free of kernel memory.
The bug permits malicious code to trigger a write-after-free, which may be used to gain root privileges or escape a jail.
Insufficient validation of environment variables in the telnet client supplied in FreeBSD can lead to stack-based buffer overflows. A stack- based overflow is present in the handling of environment variables when connecting via the telnet client to remote telnet servers.
This issue only affects the telnet client. Inbound telnet sessions to telnetd(8) are not affected by this issue.
These buffer overflows may be triggered when connecting to a malicious server, or by an active attacker in the network path between the client and server. Specially crafted TELNET command sequences may cause the execution of arbitrary code with the privileges of the user invoking telnet(1).
To implement one particular ioctl, the Linux emulation code used a special interface present in the cd(4) driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd(4) device to arbitrarily overwrite kernel memory when some media is present in the device.
A user in the operator group can make use of this interface to gain root privileges on a system with a cd(4) device when some media is present in the device.
A bug causes up to three bytes of kernel stack memory to be written to disk as uninitialized directory entry padding. This data can be viewed by any user with read access to the directory. Additionally, a malicious user with write access to a directory can cause up to 254 bytes of kernel stack memory to be exposed.
Some amount of the kernel stack is disclosed and written out to the filesystem.
With certain inputs, iconv may write beyond the end of the output buffer.
Depending on the way in which iconv is used, an attacker may be able to create a denial of service, provoke incorrect program behavior, or induce a remote code execution. iconv is a libc library function and the nature of possible attacks will depend on the way in which iconv is used by applications or daemons.
While processing acknowledgements, the RACK code uses several linked lists to maintain state entries. A malicious attacker can cause the lists to grow unbounded. This can cause an expensive list traversal on every packet being processed, leading to resource exhaustion and a denial of service.
An attacker with the ability to send specially crafted TCP traffic to a victim system can degrade network performance and/or consume excessive CPU by exploiting the inefficiency of traversing the potentially very large RACK linked lists with relatively small bandwidth cost.
On some Intel processors utilizing speculative execution a local process may be able to infer stale information from microarchitectural buffers to obtain a memory disclosure.
An attacker may be able to read secret data from the kernel or from a process when executing untrusted code (for example, in a web browser).
States in pf(4) let ICMP and ICMP6 packets pass if they have a packet in their payload matching an existing condition. pf(4) does not check if the outer ICMP or ICMP6 packet has the same destination IP as the source IP of the inner protocol packet.
A maliciously crafted ICMP/ICMP6 packet could bypass the packet filter rules and be passed to a host that would otherwise be unavailable.
A bug in the pf(4) IPv6 fragment reassembly logic incorrectly uses the last extension header offset from the last received packet instead of from the first packet.
Malicious IPv6 packets with different IPv6 extensions could cause a kernel panic or potentially a filtering rule bypass.

Matrix developers report:
The matrix team releases Synapse 1.2.1 as a critical security update. It contains patches relating to redactions and event federation:
- Prevent an attack where a federated server could send redactions for arbitrary events in v1 and v2 rooms.
- Prevent a denial-of-service attack where cycles of redaction events would make Synapse spin infinitely.
- Prevent an attack where users could be joined or parted from public rooms without their consent.
- Fix a vulnerability where a federated server could spoof read-receipts from users on other servers.
- It was possible for a room moderator to send a redaction for an m.room.create event, which would downgrade the room to version 1.
Exim team report:
A local or remote attacker can execute programs with root privileges - if you've an unusual configuration.
If your configuration uses the ${sort } expansion for items that can be controlled by an attacker (e.g. $local_part, $domain). The default config, as shipped by the Exim developers, does not contain ${sort }.
The vulnerability is exploitable either remotely or locally and could be used to execute other programs with root privilege. The ${sort } expansion re-evaluates its items.
Exim 4.92.1 is not vulnerable.
Oracle reports:
This Critical Patch Update contains 45 new security fixes for Oracle MySQL. 4 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.
Drupal Security Team reports:
In Drupal 8.7.4, when the experimental Workspaces module is enabled, an access bypass condition is created.
This can be mitigated by disabling the Workspaces module. It does not affect any release other than Drupal 8.7.4.
Simon Tatham reports:
Vulnerabilities fixed in this release include:
- A malicious SSH-1 server could trigger a buffer overrun by sending extremely short RSA keys, or certain bad packet length fields. Either of these could happen before host key verification, so even if you trust the server you *intended* to connect to, you would still be at risk.
(However, the SSH-1 protocol is obsolete, and recent versions of PuTTY do not try it by default, so you are only at risk if you work with old servers and have explicitly configured SSH-1.)- If a malicious process found a way to impersonate Pageant, then it could cause an integer overflow in any of the SSH client tools (PuTTY, Plink, PSCP, PSFTP) which accessed the malicious Pageant.
Other security-related bug fixes include:
- The 'trust sigil' system introduced in PuTTY 0.71 to protect against server spoofing attacks had multiple bugs. Trust sigils were not turned off after login in the SSH-1 and Rlogin protocols, and not turned back on if you used the Restart Session command. Both are now fixed.

Buildbot accepted user-submitted authorization token from OAuth and used it to authenticate user.
The vulnerability can lead to malicious attackers to authenticate as legitimate users of a Buildbot instance without knowledge of the victim's login credentials on certain scenarios.
If an attacker has an application authorized to access data of another user at the same Identity Provider as the used by the Buildbot instance, then he can acquire a token to access the data of that user, supply the token to the Buildbot instance and successfully login as the victim.
Jon Siwek of Corelight reports:
The following Denial of Service vulnerabilities are addressed:
- Integer type mismatches in BinPAC-generated parser code and Bro analyzer code may allow for crafted packet data to cause unintentional code paths in the analysis logic to be taken due to unsafe integer conversions causing the parser and analysis logic to each expect different fields to have been parsed. One such example, reported by Maksim Shudrak, causes the Kerberos analyzer to dereference a null pointer. CVE-2019-12175 was assigned for this issue.
- The Kerberos parser allows for several fields to be left uninitialized, but they were not marked with an &optional attribute and several usages lacked existence checks. Crafted packet data could potentially cause an attempt to access such uninitialized fields, generate a runtime error/exception, and leak memory. Existence checks and &optional attributes have been added to the relevent Kerberos fields.
- BinPAC-generated protocol parsers commonly contain fields whose length is derived from other packet input, and for those that allow for incremental parsing, BinPAC did not impose a limit on how large such a field could grow, allowing for remotely-controlled packet data to cause growth of BinPAC's flowbuffer bounded only by the numeric limit of an unsigned 64-bit integer, leading to memory exhaustion. There is now a generalized limit for how large flowbuffers are allowed to grow, tunable by setting "BinPAC::flowbuffer_capacity_max".

CVE-2019-11470: The cineon parsing component in ImageMagick 7.0.8-26 Q16 allows attackers to cause a denial-of-service (uncontrolled resource consumption) by crafting a Cineon image with an incorrect claimed image size. This occurs because ReadCINImage in coders/cin.c lacks a check for insufficient image data in a file.
CVE-2019-11472: ReadXWDImage in coders/xwd.c in the XWD image parsing component of ImageMagick 7.0.8-41 Q16 allows attackers to cause a denial-of-service (divide-by-zero error) by crafting an XWD image file in which the header indicates neither LSB first nor MSB first.
CVE-2019-11597: In ImageMagick 7.0.8-43 Q16, there is a heap-based buffer over-read in the function WriteTIFFImage of coders/tiff.c, which allows an attacker to cause a denial of service or possibly information disclosure via a crafted image file.

Fixed CVE-2019-11356: buffer overrun in httpd
MITRE:
Serendipity before 2.1.5 has XSS via EXIF data that is mishandled in the templates/2k11/admin/media_choose.tpl Editor Preview feature or the templates/2k11/admin/media_items.tpl Media Library feature.
MITRE reports:
An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0. A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote code execution. An attacker can send a malicious SQL command to trigger this vulnerability.
Mitre reports:
An issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the function SSHParseBanner is composed only of a \n character, then the program runs into a heap-based buffer over-read. This occurs because the erroneous search for \r results in an integer underflow.
curl security problems:
CVE-2019-5435: Integer overflows in curl_url_set()
libcurl contains two integer overflows in the curl_url_set() function that if triggered, can lead to a too small buffer allocation and a subsequent heap buffer overflow.
The flaws only exist on 32 bit architectures and require excessive string input lengths.
CVE-2019-5436: TFTP receive buffer overflow
libcurl contains a heap buffer overflow in the function (tftp_receive_packet()) that recevives data from a TFTP server. It calls recvfrom() with the default size for the buffer rather than with the size that was used to allocate it. Thus, the content that might overwrite the heap memory is entirely controlled by the server.
The flaw exists if the user selects to use a "blksize" of 504 or smaller (default is 512). The smaller size that is used, the larger the possible overflow becomes.
Users chosing a smaller size than default should be rare as the primary use case for changing the size is to make it larger.
It is rare for users to use TFTP across the Internet. It is most commonly used within local networks.
MITRE reports:
OCaml before 4.03.0 does not properly handle sign extensions, which allows remote attackers to conduct buffer overflow attacks or obtain sensitive information as demonstrated by a long string to the String.copy function.

Sean McArthur reports:
The Rust Programming Language Standard Library 1.34.x before 1.34.2 contains a stabilized method which, if overridden, can violate Rust's safety guarantees and cause memory unsafety. If the Error::type_id method is overridden then any type can be safely cast to any other type, causing memory safety vulnerabilities in safe code (e.g., out-of-bounds write or read). Code that does not manually implement Error::type_id is unaffected.

The PostgreSQL project reports:
PostgreSQL maintains statistics for tables by sampling data available in columns; this data is consulted during the query planning process. Prior to this release, a user able to execute SQL queries with permissions to read a given column could craft a leaky operator that could read whatever data had been sampled from that column. If this happened to include values from rows that the user is forbidden to see by a row security policy, the user could effectively bypass the policy. This is fixed by only allowing a non-leakproof operator to use this data if there are no relevant row security policies for the table.
The PostgreSQL project reports:
Prior to this release, a user running PostgreSQL 11 can read arbitrary bytes of server memory by executing a purpose-crafted INSERT statement to a partitioned table.

All wpa_supplicant and hostapd versions with EAP-pwd support could suffer a denial of service attack through process termination.
EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP peer) does not to validate the received scalar and element values in EAP-pwd-Commit messages properly. This could result in attacks that would be able to complete EAP-pwd authentication exchange without the attacker having to know the used password.
See https://w1.fi/security/2019-4/eap-pwd-missing-commit-validation.txt for a detailed description of the bug.
All wpa_supplicant and hostapd versions with EAP-pwd support.
When hostapd is used to operate an access point with SAE (Simultaneous Authentication of Equals; also known as WPA3-Personal), an invalid authentication sequence could result in the hostapd process terminating due to a NULL pointer dereference when processing SAE confirm message. This was caused by missing state validation steps when processing the SAE confirm message in hostapd/AP mode.
See https://w1.fi/security/2019-3/sae-confirm-missing-state-validation.txt for a detailed description of the bug.
All hostapd versions with SAE support (CONFIG_SAE=y in the build configuration and SAE being enabled in the runtime configuration).
Potential side channel attacks in the SAE implementations used by both hostapd and wpa_supplicant (see CVE-2019-9494 and VU#871675). EAP-pwd uses a similar design for deriving PWE from the password and while a specific attack against EAP-pwd is not yet known to be tested, there is no reason to believe that the EAP-pwd implementation would be immune against the type of cache attack that was identified for the SAE implementation. Since the EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP peer) does not support MODP groups, the timing attack described against SAE is not applicable for the EAP-pwd implementation.
See https://w1.fi/security/2019-2/eap-pwd-side-channel-attack.txt for a detailed description of the bug.
All wpa_supplicant and hostapd versions with EAP-pwd support (CONFIG_EAP_PWD=y in the build configuration and EAP-pwd being enabled in the runtime configuration).
Side channel attacks in the SAE implementations used by both hostapd (AP) and wpa_supplicant (infrastructure BSS station/mesh station). SAE (Simultaneous Authentication of Equals) is also known as WPA3-Personal. The discovered side channel attacks may be able to leak information about the used password based on observable timing differences and cache access patterns. This might result in full password recovery when combined with an offline dictionary attack and if the password is not strong enough to protect against dictionary attacks.

Jupyter blog:
Login pages tend to take a parameter for redirecting back to a page after successful login, e.g. /login?next=/notebooks/mynotebook.ipynb, so that you aren't disrupted too much if you try to visit a page, but have to authenticate first. An Open Redirect Vulnerability is when a malicious person crafts a link pointing to the login page of a trusted site, but setting the "redirect after successful login" parameter to send the user to their own site, instead of a page on the authenticated site (the notebook or JupyterHub server), e.g. /login?next=http://badwebsite.biz. This doesn't necessarily compromise anything immediately, but it enables phishing if users don't notice that the domain has changed, e.g. by showing a fake "re-enter your password" page. Servers generally have to validate the redirect URL to avoid this. Both JupyterHub and Notebook already do this, but the validation didn't take into account all possible ways to redirect to other sites, so some malicious URLs could still be crafted to redirect away from the server (the above example does not work in any recent version of either package). Only certain browsers (Chrome and Firefox, not Safari) could be redirected from the JupyterHub login page, but all browsers could be redirected away from a standalone notebook server.
Aki Tuomi reports:
Vulnerability Details: When reading FTS or POP3-UIDL header from dovecot index, the input buffer size is not bound, and data is copied to target structure causing stack overflow. Risk: This can be used for local root privilege escalation or executing arbitrary code in dovecot process context. This requires ability to directly modify dovecot indexes. Steps to reproduce: Produce dovecot.index.log entry that creates an FTS header which has more than 12 bytes of data. Trigger dovecot indexer-worker or run doveadm index. Dovecot will crash. Mitigations: Since 2.3.0 dovecot has been compiled with stack smash protection, ASLR, read-only GOT tables and other techniques that make exploiting this bug much harder.

PowerDNS developers report:
An issue has been found in PowerDNS Authoritative Server when the HTTP remote backend is used in RESTful mode (without post=1 set), allowing a remote user to cause the HTTP backend to connect to an attacker-specified host instead of the configured one, via a crafted DNS query. This can be used to cause a denial of service by preventing the remote backend from getting a response, content spoofing if the attacker can time its own query so that subsequent queries will use an attacker-controlled HTTP server instead of the configured one, and possibly information disclosure if the Authoritative Server has access to internal servers.

The OpenSSL project reports:
Low: ChaCha20-Poly1305 with long nonces (CVE-2019-1543)
ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value (IV) should be 96 bits (12 bytes). OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also incorrectly allows a nonce to be set of up to 16 bytes. In this case only the last 12 bytes are significant and any additional leading bytes are ignored.
Network Time Foundation reports:
A crafted malicious authenticated mode 6 (ntpq) packet from a permitted network address can trigger a NULL pointer dereference, crashing ntpd.
Note that for this attack to work, the sending system must be on an address that the target's ntpd accepts mode 6 packets from, and must use a private key that is specifically listed as being used for mode 6 authorization.
Impact: The ntpd daemon can crash due to the NULL pointer dereference, causing a denial of service.
Mitigation:
- Use restrict noquery to limit addresses that can send mode 6 queries.
- Limit access to the private controlkey in ntp.keys.
- Upgrade to 4.2.8p13, or later.

Updates are now available for all active Node.js release lines. In addition to fixes for security flaws in Node.js, they also include upgrades of Node.js 6 and 8 to OpenSSL 1.0.2r which contains a fix for a moderate severity security vulnerability.
For these releases, we have decided to withhold the fix for the Misinterpretation of Input (CWE-115) flaw mentioned in the original announcement. This flaw is very low severity and we are not satisfied that we had a complete and stable fix ready for release. We will be seeking to address this flaw via alternate mechanisms in the near future. In addition, we have introduced an additional CVE for a change in Node.js 6 that we have decided to classify as a Denial of Service (CWE-400) flaw.
We recommend that all Node.js users upgrade to a version listed below as soon as possible.
OpenSSL: 0-byte record padding oracle (CVE-2019-1559)
OpenSSL 1.0.2r contains a fix for CVE-2019-1559 and is included in the releases for Node.js versions 6 and 8 only. Node.js 10 and 11 are not impacted by this vulnerability as they use newer versions of OpenSSL which do not contain the flaw.
Under certain circumstances, a TLS server can be forced to respond differently to a client if a zero-byte record is received with an invalid padding compared to a zero-byte record with an invalid MAC. This can be used as the basis of a padding oracle attack to decrypt data.
Only TLS connections using certain ciphersuites executing under certain conditions are exploitable. We are currently unable to determine whether the use of OpenSSL in Node.js exposes this vulnerability. We are taking a cautionary approach and recommend the same for users. For more information, see the advisory and a detailed write-up by the reporters of the vulnerability.

Some field types do not properly sanitize data from non-form sources. This can lead to arbitrary PHP code execution in some cases..
The OpenSSL project reports:
0-byte record padding oracle (CVE-2019-1559) (Moderate)
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data.
msmtp developers report:
In msmtp 1.8.2, when tls_trust_file has its default configuration, certificate-verification results are not properly checked.

CVE-2019-5785: Integer overflow in Skia
CVE-2018-18511: Cross-origin theft of images with ImageBitmapRenderingContext
Adobe reports:
- This update resolves an out-of-bounds vulnerability that could lead to information disclosure (CVE-2019-7090).
NVD reports:
In OpenJPEG 2.3.0, there is an integer overflow vulnerability in the opj_t1_encode_cblks function (openjp2/t1.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.
FreeBSD 12.0 attempts to handle the case where the receiving process does not provide a sufficiently large buffer for an incoming control message containing rights. In particular, to avoid leaking the corresponding descriptors into the receiving process' descriptor table, the kernel handles the truncation case by closing descriptors referenced by the discarded message.
The code which performs this operation failed to release a reference obtained on the file corresponding to a received right. This bug can be used to cause the reference counter to wrap around and free the file structure.
A local user can exploit the bug to gain root privileges or escape from a jail.
The callee-save registers are used by kernel and for some of them (%r8, %r10, and for non-PTI configurations, %r9) the content is not sanitized before return from syscalls, potentially leaking sensitive information.
Typically an address of some kernel data structure used in the syscall implementation, is exposed.

CVE-2019-7401: a head memory buffer overflow might have
been caused in the router process by a specially crafted
request, potentially resulting in a segmentation fault
or other unspecified behavior.
curl security problems:
CVE-2018-16890: NTLM type-2 out-of-bounds buffer read
libcurl contains a heap buffer out-of-bounds read flaw.
The function handling incoming NTLM type-2 messages (lib/vauth/ntlm.c:ntlm_decode_type2_target) does not validate incoming data correctly and is subject to an integer overflow vulnerability.
Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.
CVE-2019-3822: NTLMv2 type-3 header stack buffer overflow
libcurl contains a stack based buffer overflow vulnerability.
The function creating an outgoing NTLM type-3 header (lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening.
This output data can grow larger than the local buffer if very large "nt response" data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server.
Such a "large value" needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.
CVE-2019-3823: SMTP end-of-response out-of-bounds read
libcurl contains a heap out-of-bounds read in the code handling the end-of-response for SMTP.
If the buffer passed to smtp_endofresp() isn't NUL terminated and contains no character ending the parsed number, and len is set to 5, then the strtol() call reads beyond the allocated buffer. The read contents will not be returned to the caller.
Gitlab reports:
Leak of Confidential Issue and Merge Request Titles
Persistent XSS in User Status
Aki Tuomi (Open-Xchange Oy) reports:
Normally Dovecot is configured to authenticate imap/pop3/managesieve/submission clients using regular username/password combination. Some installations have also required clients to present a trusted SSL certificate on top of that. It's also possible to configure Dovecot to take the username from the certificate instead of from the user provided authentication. It's also possible to avoid having a password at all, only trusting the SSL certificate. If the provided trusted SSL certificate is missing the username field, Dovecot should be failing the authentication. However, the earlier versions will take the username from the user provided authentication fields (e.g. LOGIN command). If there is no additional password verification, this allows the attacker to login as anyone else in the system. This affects only installations using: auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = yes Attacker must also have access to a valid trusted certificate without the ssl_cert_username_field in it. The default is commonName, which almost certainly exists in all certificates. This could happen for example if ssl_cert_username_field is a field that normally doesn't exist, and attacker has access to a web server's certificate (and key), which is signed with the same CA. Attack can be migitated by having the certificates with proper Extended Key Usage, such as 'TLS Web Server' and 'TLS Web Server Client'. Also, ssl_cert_username_field setting was ignored with external SMTP AUTH, because none of the MTAs (Postfix, Exim) currently send the cert_username field. This may have allowed users with trusted certificate to specify any username in the authentication. This does not apply to Dovecot Submission service.

The phpMyAdmin development team reports:
Summary
Arbitrary file read vulnerability
Description
When
AllowArbitraryServer
configuration set totrue
, with the use of a rogue MySQL server, an attacker can read any file on the server that the web server's user can access.phpMyadmin attempts to block the use of
LOAD DATA INFILE
, but due to a bug in PHP, this check is not honored. Additionally, when using the 'mysql' extension, mysql.allow_local_infile is enabled by default. Both of these conditions allow the attack to occur.Severity
We consider this vulnerability to be critical.
Mitigation factor
This attack can be mitigated by setting the `AllowArbitraryServer` configuration directive to false (which is the default value).
Affected Versions
phpMyAdmin versions from at least 4.0 through 4.8.4 are affected
Summary
SQL injection in Designer feature
Description
A vulnerability was reported where a specially crafted username can be used to trigger an SQL injection attack through the designer feature.
Severity

Prevent DeleteFilePost doing arbitrary deletion
A vulnerability has been found that would allow attackers to direct a peer to jump to and execute from an address indicated by the attacker. This issue has been present since v4.2.0. Older releases are not affected. NOTE: The attacker needs to know in advance valid addresses in the peer's memory to jump to, so measures like ASLR are effective mitigations. NOTE: this attack can only take place after authentication, so peers behind CURVE/GSSAPI are not vulnerable to unauthenticated attackers.

The Shibboleth Consortium reports:
SAML messages, assertions, and metadata all commonly contain date/time information in a standard XML format.
Invalid formatted data in such fields cause an exception of a type that was not handled properly in the V3 software and causes a crash (usually to the shibd daemon process, but possibly to Apache in rare cases). Note that the crash occurs prior to evaluation of a message's authenticity, so can be exploited by an untrusted attacker.
The problem is believed to be specific to the V3 software and would not cause a crash in the older, now unsupported, V2 software.

Typo3 core team reports:
CKEditor 4.11 fixes an XSS vulnerability in the HTML parser reported by maxarr. The vulnerability stemmed from the fact that it was possible to execute XSS inside the CKEditor source area after persuading the victim to: (i) switch CKEditor to source mode, then (ii) paste a specially crafted HTML code, prepared by the attacker, into the opened CKEditor source area, and (iii) switch back to WYSIWYG mode. Although this is an unlikely scenario, we recommend to upgrade to the latest editor version.
Failing to properly encode user input, online media asset rendering (*.youtube and *.vimeo files) is vulnerable to cross-site scripting. A valid backend user account or write access on the server system (e.g. SFTP) is needed in order to exploit this vulnerability.
Failing to properly encode user input, notifications shown in modal windows in the TYPO3 backend are vulnerable to cross-site scripting. A valid backend user account is needed in order to exploit this vulnerability.
Failing to properly encode user input, login status display is vulnerable to cross-site scripting in the website frontend. A valid user account is needed in order to exploit this vulnerability - either a backend user or a frontend user having the possibility to modify their user profile.
Template patterns that are affected are:
- ###FEUSER_[fieldName]### using system extension felogin
- <!--###USERNAME###--> for regular frontend rendering (pattern can be defined individually using TypoScript setting config.USERNAME_substToken)
It has been discovered that cookies created in the Install Tool are not hardened to be submitted only via HTTP. In combination with other vulnerabilities such as cross-site scripting it can lead to hijacking an active and valid session in the Install Tool.
The Install Tool exposes the current TYPO3 version number to non-authenticated users.
Online Media Asset Handling (*.youtube and *.vimeo files) in the TYPO3 backend is vulnerable to denial of service. Putting large files with according file extensions results in high consumption of system resources. This can lead to exceeding limits of the current PHP process which results in a dysfunctional backend component. A valid backend user account or write access on the server system (e.g. SFTP) is needed in order to exploit this vulnerability.
TYPO3’s built-in record registration functionality (aka “basic shopping cart”) using recs URL parameters is vulnerable to denial of service. Failing to properly ensure that anonymous user sessions are valid, attackers can use this vulnerability in order to create an arbitrary amount of individual session-data records in the database.

The phpMyAdmin development team reports:
Summary
Local file inclusion through transformation feature
Description
A flaw has been found where an attacker can exploit phpMyAdmin to leak the contents of a local file. The attacker must have access to the phpMyAdmin Configuration Storage tables, although these can easily be created in any database to which the attacker has access. An attacker must have valid credentials to log in to phpMyAdmin; this vulnerability does not allow an attacker to circumvent the login system.
Severity
We consider this vulnerability to be severe.
Summary
XSRF/CSRF vulnerability in phpMyAdmin
Description
By deceiving a user to click on a crafted URL, it is possible to perform harmful SQL operations such as renaming databases, creating new tables/routines, deleting designer pages, adding/deleting users, updating user passwords, killing SQL processes, etc.
Severity
We consider this vulnerability to be of moderate severity.
Summary
XSS vulnerability in navigation tree
Description
A Cross-Site Scripting vulnerability was found in the navigation tree, where an attacker can deliver a payload to a user through a specially-crafted database/table name.
Severity
We consider this attack to be of moderate severity.
Mitigation factor
The stored XSS vulnerabilities can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required forms.

We recommend that all Node.js users upgrade to a version listed below as soon as possible.
Debugger port 5858 listens on any interface by default (CVE-2018-12120)
All versions of Node.js 6 are vulnerable and the severity is HIGH. When the debugger is enabled with
node --debug
ornode debug
, it listens to port 5858 on all interfaces by default. This may allow remote computers to attach to the debug port and evaluate arbitrary JavaScript. The default interface is now localhost. It has always been possible to start the debugger on a specific interface, such asnode --debug=localhost
. The debugger was removed in Node.js 8 and replaced with the inspector, so no versions from 8 and later are vulnerable.Denial of Service with large HTTP headers (CVE-2018-12121)
All versions of 6 and later are vulnerable and the severity is HIGH. By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer.
The total size of HTTP headers received by Node.js now must not exceed 8192 bytes.
"Slowloris" HTTP Denial of Service (CVE-2018-12122)
All versions of Node.js 6 and later are vulnerable and the severity is LOW. An attacker can cause a Denial of Service (DoS) by sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time. Attack potential is mitigated by the use of a load balancer or other proxy layer.
A timeout of 40 seconds now applies to servers receiving HTTP headers. This value can be adjusted with
server.headersTimeout
. Where headers are not completely received within this period, the socket is destroyed on the next received chunk. In conjunction withserver.setTimeout()
, this aids in protecting against excessive resource retention and possible Denial of Service.Hostname spoofing in URL parser for javascript protocol (CVE-2018-12123)
All versions of Node.js 6 and later are vulnerable and the severity is LOW. If a Node.js application is using
url.parse()
to determine the URL hostname, that hostname can be spoofed by using a mixed case "javascript:" (e.g. "javAscript:") protocol (other protocols are not affected). If security decisions are made about the URL based on the hostname, they may be incorrect.HTTP request splitting (CVE-2018-12116)
Node.js 6 and 8 are vulnerable and the severity is MEDIUM. If Node.js can be convinced to use unsanitized user-provided Unicode data for the
path
option of an HTTP request, then data can be provided which will trigger a second, unexpected, and user-defined HTTP request to made to the same server.OpenSSL Timing vulnerability in ECDSA signature generation (CVE-2018-0735)
The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a timing side-channel attack. An attacker could use variations in the signing algorithm to recover the private key.
OpenSSL Timing vulnerability in DSA signature generation (CVE-2018-0734)
The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side-channel attack. An attacker could use variations in the signing algorithm to recover the private key.
OpenSSL Microarchitecture timing vulnerability in ECC scalar multiplication (CVE-2018-5407)
OpenSSL ECC scalar multiplication, used in e.g. ECDSA and ECDH, has been shown to be vulnerable to a microarchitecture timing side-channel attack. An attacker with sufficient access to mount local timing attacks during ECDSA signature generation could recover the private key.
powerdns Team reports:
CVE-2018-16855: An issue has been found in PowerDNS Recursor where a remote attacker sending a DNS query can trigger an out-of-bounds memory read while computing the hash of the query for a packet cache lookup, possibly leading to a crash. When the PowerDNS Recursor is run inside a supervisor like supervisord or systemd, a crash will lead to an automatic restart, limiting the impact to a somewhat degraded service.

Albert Astals Cid reports:
messagelib is the library used by KMail to display emails.
messagelib by default displays emails as plain text, but gives the user an option to "Prefer HTML to plain text" in the settings and if that option is not enabled there is way to enable HTML display when an email contains HTML.
Some HTML emails can trick messagelib into opening a new browser window when displaying said email as HTML.
This happens even if the option to allow the HTML emails to access remote servers is disabled in KMail settings.
This means that the owners of the servers referred in the email can see in their access logs your IP address.
FasterXML jackson-databind before 2.8.11.1 and 2.9.x before 2.9.5 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the c3p0 libraries are available in the classpath.
When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

The samba project reports:
All versions of Samba from 4.0.0 onwards are vulnerable to infinite query recursion caused by CNAME loops. Any dns record can be added via ldap by an unprivileged user using the ldbadd tool, so this is a security issue.
When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ.
During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process.
During the processing of an DNS zone in the DNS management DCE/RPC server, the internal DNS server or the Samba DLZ plugin for BIND9, if the DSPROPERTY_ZONE_MASTER_SERVERS property or DSPROPERTY_ZONE_SCAVENGING_SERVERS property is set, the server will follow a NULL pointer and terminate
A user in a Samba AD domain can crash the KDC when Samba is built in the non-default MIT Kerberos configuration.
AD DC Configurations watching for bad passwords (to restrict brute forcing of passwords) in a window of more than 3 minutes may not watch for bad passwords at all.

PowerDNS Team reports:
CVE-2018-10851: An issue has been found in PowerDNS Authoritative Server allowing an authorized user to cause a memory leak by inserting a specially crafted record in a zone under their control, then sending a DNS query for that record. The issue is due to the fact that some memory is allocated before the parsing and is not always properly released if the record is malformed. When the PowerDNS Authoritative Server is run inside the guardian (--guardian), or inside a supervisor like supervisord or systemd, an out-of-memory crash will lead to an automatic restart, limiting the impact to a somewhat degraded service.
CVE-2018-14626: An issue has been found in PowerDNS Authoritative Server allowing a remote user to craft a DNS query that will cause an answer without DNSSEC records to be inserted into the packet cache and be returned to clients asking for DNSSEC records, thus hiding the presence of DNSSEC signatures for a specific qname and qtype. For a DNSSEC-signed domain, this means that DNSSEC validating clients will consider the answer to be bogus until it expires from the packet cache, leading to a denial of service.

CVE-2018-14644: An issue has been found in PowerDNS Recursor where a remote attacker sending a DNS query for a meta-type like OPT can lead to a zone being wrongly cached as failing DNSSEC validation. It only arises if the parent zone is signed, and all the authoritative servers for that parent zone answer with FORMERR to a query for at least one of the meta-types. As a result, subsequent queries from clients requesting DNSSEC validation will be answered with a ServFail.

Albert Astals Cid reports:
Various KDE applications share a plugin system to create thumbnails of various file types for displaying in file managers, file dialogs, etc. kio-extras contains a thumbnailer plugin for HTML files.
The HTML thumbnailer was incorrectly accessing some content of remote URLs listed in HTML files. This meant that the owners of the servers referred in HTML files in your system could have seen in their access logs your IP address every time the thumbnailer tried to create the thumbnail.
The HTML thumbnailer has been removed in upcoming KDE Applications 18.12.0 because it was actually not creating thumbnails for files at all.
NVD reports:
An issue was discovered in GNU patch through 2.7.6. There is a segmentation fault, associated with a NULL pointer dereference, leading to a denial of service in the intuit_diff_type function in pch.c, aka a "mangled rename" issue.
A double free exists in the another_hunk function in pch.c in GNU patch through 2.7.6.
GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files, specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution. This attack appear to be exploitable via a patch file processed via the patch utility. This is similar to FreeBSD's CVE-2015-1418 however although they share a common ancestry the code bases have diverged over time.

The PostgreSQL project reports:
CVE-2018-16850: SQL injection in pg_upgrade and pg_dump, via CREATE TRIGGER ... REFERENCING.
Using a purpose-crafted trigger definition, an attacker can run arbitrary SQL statements with superuser privileges when a superuser runs pg_upgrade on the database or during a pg_dump dump/restore cycle. This attack requires a CREATE privilege on some non-temporary schema or a TRIGGER privilege on a table. This is exploitable in the default PostgreSQL configuration, where all users have CREATE privilege on public schema.
NGINX Team reports:
Two security issues were identified in nginx HTTP/2 implementation, which might cause excessive memory consumption (CVE-2018-16843) and CPU usage (CVE-2018-16844).
The issues affect nginx compiled with the ngx_http_v2_module (not compiled by default) if the "http2" option of the "listen" directive is used in a configuration file.
A security issue was identified in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory isclosure by using a specially crafted mp4 file (CVE-2018-16845).
The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the "mp4" directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module.

curl security problems:
CVE-2018-16839: SASL password overflow via integer overflow
libcurl contains a buffer overrun in the SASL authentication code.
The internal function Curl_auth_create_plain_message fails to correctly verify that the passed in lengths for name and password aren't too long, then calculates a buffer size to allocate.
On systems with a 32 bit size_t, the math to calculate the buffer size triggers an integer overflow when the user name length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow.
This bug is very similar to CVE-2017-14618.
It affects curl 7.33.0 to 7.61.1.
CVE-2018-16840: use-after-free in handle close
libcurl contains a heap use-after-free flaw in code related to closing an easy handle.
When closing and cleaning up an "easy" handle in the Curl_close() function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.
It affects curl 7.59.0 to 7.61.1.
CVE-2018-16842: warning message out-of-buffer read
curl contains a heap out of buffer read vulnerability.
The command line tool has a generic function for displaying warning and informational messages to stderr for various situations. For example if an unknown command line argument is used, or passed to it in a "config" file.
This display function formats the output to wrap at 80 columns. The wrap logic is however flawed, so if a single word in the message is itself longer than 80 bytes the buffer arithmetic calculates the remainder wrong and will end up reading behind the end of the buffer. This could lead to information disclosure or crash.
This vulnerability could lead to a security issue if used in this or similar situations:
1. a server somewhere uses the curl command line to run something
2. if it fails, it shows stderr to the user
3. the server takes user input for parts of its command line input
4. user provides something overly long that triggers this crash
5. the stderr output may now contain user memory contents that wasn't meant to be available
It affects curl 7.14.1 to 7.61.1.

Ruby news:
CVE-2018-16395: OpenSSL::X509::Name equality check does not work correctly
An instance of OpenSSL::X509::Name contains entities such as CN, C and so on. Some two instances of OpenSSL::X509::Name are equal only when all entities are exactly equal. However, there is a bug that the equality check is not correct if the value of an entity of the argument (right-hand side) starts with the value of the receiver (left-hand side). So, if a malicious X.509 certificate is passed to compare with an existing certificate, there is a possibility to be judged incorrectly that they are equal.
CVE-2018-16396: Tainted flags are not propagated in Array#pack and String#unpack with some directives
Array#pack method converts the receiver's contents into a string with specified format. If the receiver contains some tainted objects, the returned string also should be tainted. String#unpack method which converts the receiver into an array also should propagate its tainted flag to the objects contained in the returned array. But, with B, b, H and h directives, the tainted flags are not propagated. So, if a script processes unreliable inputs by Array#pack and/or String#unpack with these directives and checks the reliability with tainted flags, the check might be wrong.

CVE-2018-17144, a fix for which was released on September 18th in Bitcoin Core versions 0.16.3 and 0.17.0rc4, includes both a Denial of Service component and a critical inflation vulnerability. It was originally reported to several developers working on Bitcoin Core, as well as projects supporting other cryptocurrencies, including ABC and Unlimited on September 17th as a Denial of Service bug only, however we quickly determined that the issue was also an inflation vulnerability with the same root cause and fix.
the Apache Spamassassin project reports:
In Apache SpamAssassin, using HTML::Parser, we setup an object and hook into the begin and end tag event handlers In both cases, the "open" event is immediately followed by a "close" event - even if the tag *does not* close in the HTML being parsed.
Because of this, we are missing the "text" event to deal with the object normally. This can cause carefully crafted emails that might take more scan time than expected leading to a Denial of Service.

Chris reports:
The XML parsing engine for Plex Media Server's SSDP/UPNP functionality is vulnerable to an XML External Entity Processing (XXE) attack. Unauthenticated attackers on the same LAN can use this vulnerability to:
- Access arbitrary files from the filesystem with the same permission as the user account running Plex.
- Initiate SMB connections to capture NetNTLM challenge/response and crack to clear-text password.
- Initiate SMB connections to relay NetNTLM challenge/response and achieve Remote Command Execution in Windows domains.
MITRE reports:
An issue was discovered in SDDM through 0.17.0. If configured with ReuseSession=true, the password is not checked for users with an already existing session. Any user with access to the system D-Bus can therefore unlock any graphical session.

curl security problems:
CVE-2018-14618: NTLM password overflow via integer overflow
The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap.
The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow.
This bug is almost identical to CVE-2017-8816.

CERT reports:
Ghostscript contains an optional -dSAFER option, which is supposed to prevent unsafe PostScript operations. Multiple PostScript operations bypass the protections provided by -dSAFER, which can allow an attacker to execute arbitrary commands with arbitrary arguments. This vulnerability can also be exploited in applications that leverage Ghostscript, such as ImageMagick, GraphicsMagick, evince, Okular, Nautilus, and others.
Exploit code for this vulnerability is publicly available.
Grafana Labs reports:
On the 20th of August at 1800 CEST we were contacted about a potential security issue with the “remember me” cookie Grafana sets upon login. The issue targeted users without a local Grafana password (LDAP & OAuth users) and enabled a potential attacker to generate a valid cookie knowing only a username.
All installations which use the Grafana LDAP or OAuth authentication features must be upgraded as soon as possible. If you cannot upgrade, you should switch authentication mechanisms or put additional protections in front of Grafana such as a reverse proxy.

Corelight reports:
Bro 2.5.5 primarily addresses security issues:
- Fix array bounds checking in BinPAC: for arrays that are fields within a record, the bounds check was based on a pointer to the start of the record rather than the start of the array field, potentially resulting in a buffer over-read.
- Fix SMTP command string comparisons: the number of bytes compared was based on the user-supplied string length and can lead to incorrect matches. e.g. giving a command of "X" incorrectly matched "X-ANONYMOUSTLS" (and an empty commands match anything).
Address potential vectors for Denial of Service:
- "Weird" events are now generally suppressed/sampled by default according to some tunable parameters.
- Improved handling of empty lines in several text protocol analyzers that can cause performance issues when seen in long sequences.
- Add `smtp_excessive_pending_cmds' weird which serves as a notification for when the "pending command" queue has reached an upper limit and been cleared to prevent one from attempting to slowly exhaust memory.
Node.js reports:
OpenSSL: Client DoS due to large DH parameter
This fixes a potential denial of service (DoS) attack against client connections by a malicious server. During a TLS communication handshake, where both client and server agree to use a cipher-suite using DH or DHE (Diffie-Hellman, in both ephemeral and non-ephemeral modes), a malicious server can send a very large prime value to the client. Because this has been unbounded in OpenSSL, the client can be forced to spend an unreasonably long period of time to generate a key, potentially causing a denial of service.
OpenSSL: ECDSA key extraction via local side-channel
Attackers with access to observe cache-timing may be able to extract DSA or ECDSA private keys by causing the victim to create several signatures and watching responses. This flaw does not have a CVE due to OpenSSL policy to not assign itself CVEs for local-only vulnerabilities that are more academic than practical. This vulnerability was discovered by Keegan Ryan at NCC Group and impacts many cryptographic libraries including OpenSSL.
Unintentional exposure of uninitialized memory
Only Node.js 10 is impacted by this flaw.
Node.js TSC member Nikita Skovoroda discovered an argument processing flaw that causes Buffer.alloc() to return uninitialized memory. This method is intended to be safe and only return initialized, or cleared, memory. The third argument specifying encoding can be passed as a number, this is misinterpreted by Buffer's internal "fill" method as the start to a fill operation. This flaw may be abused where Buffer.alloc() arguments are derived from user input to return uncleared memory blocks that may contain sensitive information.
Out of bounds (OOB) write
Node.js TSC member Nikita Skovoroda discovered an OOB write in Buffer that can be used to write to memory outside of a Buffer's memory space. This can corrupt unrelated Buffer objects or cause the Node.js process to crash.
When used with UCS-2 encoding (recognized by Node.js under the names 'ucs2', 'ucs-2', 'utf16le' and 'utf-16le'), Buffer#write() can be abused to write outside of the bounds of a single Buffer. Writes that start from the second-to-last position of a buffer cause a miscalculation of the maximum length of the input bytes to be written.
When using WPA2, EAPOL-Key frames with the Encrypted flag and without the MIC flag set, the data field was decrypted first without verifying the MIC. When the dta field was encrypted using RC4, for example, when negotiating TKIP as a pairwise cipher, the unauthenticated but decrypted data was subsequently processed. This opened wpa_supplicant(8) to abuse by decryption and recovery of sensitive information contained in EAPOL-Key messages.
See https://w1.fi/security/2018-1/unauthenticated-eapol-key-decryption.txt for a detailed description of the bug.
All users of the WPA2 TKIP pairwise cipher are vulnerable to information, for example, the group key.
A researcher has notified us of a DoS attack applicable to another operating system. While FreeBSD may not be vulnerable to that exact attack, we have identified several places where inadequate DoS protection could allow an attacker to consume system resources.
It is not necessary that the attacker be able to establish two-way communication to carry out these attacks. These attacks impact both IPv4 and IPv6 fragment reassembly.
In the worst case, an attacker could send a stream of crafted fragments with a low packet rate which would consume a substantial amount of CPU.
Other attack vectors allow an attacker to send a stream of crafted fragments which could consume a large amount of CPU or all available mbuf clusters on the system.
These attacks could temporarily render a system unreachable through network interfaces or temporarily render a system unresponsive. The effects of the attack should clear within 60 seconds after the attack stops.
On certain Intel 64-bit x86 systems there is a period of time during terminal fault handling where the CPU may use speculative execution to try to load data. The CPU may speculatively access the level 1 data cache (L1D). Data which would otherwise be protected may then be determined by using side channel methods.
This issue affects bhyve on FreeBSD/amd64 systems.
An attacker executing user code, or kernel code inside of a virtual machine, may be able to read secret data from the kernel or from another virtual machine.

The phpMyAdmin development team reports:
Description
A Cross-Site Scripting vulnerability was found in the file import feature, where an attacker can deliver a payload to a user through importing a specially-crafted file.
Severity
We consider this attack to be of moderate severity.
The freedesktop.org project reports:
The functions XGetFontPath, XListExtensions, and XListFonts are vulnerable to an off-by-one override on malicious server responses. The server replies consist of chunks consisting of a length byte followed by actual string, which is not NUL-terminated. While parsing the response, the length byte is overridden with '\0', thus the memory area can be used as storage of C strings later on. To be able to NUL-terminate the last string, the buffer is reserved with an additional byte of space. For a boundary check, the variable chend (end of ch) was introduced, pointing at the end of the buffer which ch initially points to. Unfortunately there is a difference in handling "the end of ch". While chend points at the first byte that must not be written to, the for-loop uses chend as the last byte that can be written to. Therefore, an off-by-one can occur.
The length value is interpreted as signed char on many systems (depending on default signedness of char), which can lead to an out of boundary write up to 128 bytes in front of the allocated storage, but limited to NUL byte(s).
If the server sends a reply in which even the first string would overflow the transmitted bytes, list[0] (or flist[0]) will be set to NULL and a count of 0 is returned. If the resulting list is freed with XFreeExtensionList or XFreeFontPath later on, the first Xfree call is turned into Xfree (NULL-1) which will most likely trigger a segmentation fault. Casting the length value to unsigned char fixes the problem and allows string values with up to 255 characters.

The samba project reports:
Samba releases 4.7.0 to 4.8.3 (inclusive) contain an error which allows authentication using NTLMv1 over an SMB1 transport (either directory or via NETLOGON SamLogon calls from a member server), even when NTLMv1 is explicitly disabled on the server.
Missing input sanitization checks on some of the input parameters to LDB database layer cause the LDAP server and DNS server to crash when following a NULL pointer.
Samba releases 3.2.0 to 4.8.3 (inclusive) contain an error in libsmbclient that could allow a malicious server to overwrite client heap memory by returning an extra long filename in a directory listing.
Missing database output checks on the returned directory attributes from the LDB database layer cause the DsCrackNames call in the DRSUAPI server to crash when following a NULL pointer.
All versions of the Samba Active Directory LDAP server from 4.0.0 onwards are vulnerable to the disclosure of confidential attribute values, both of attributes where the schema SEARCH_FLAG_CONFIDENTIAL (0x80) searchFlags bit and where an explicit Access Control Entry has been specified on the ntSecurityDescriptor.

The PostgreSQL project reports:
CVE-2018-10915: Certain host connection parameters defeat client-side security defenses
libpq, the client connection API for PostgreSQL that is also used by other connection libraries, had an internal issue where it did not reset all of its connection state variables when attempting to reconnect. In particular, the state variable that determined whether or not a password is needed for a connection would not be reset, which could allow users of features requiring libpq, such as the "dblink" or "postgres_fdw" extensions, to login to servers they should not be able to access.
CVE-2018-10925: Memory disclosure and missing authorization in `INSERT ... ON CONFLICT DO UPDATE`
An attacker able to issue CREATE TABLE can read arbitrary bytes of server memory using an upsert (`INSERT ... ON CONFLICT DO UPDATE`) query. By default, any user can exploit that. A user that has specific INSERT privileges and an UPDATE privilege on at least one column in a given table can also update other columns using a view and an upsert query.
Oracle reports:
Multiple vulnerabilities have been disclosed by Oracle without further detail. CVSS scores 7.1 - 2.7
The shibboleth project reports:
SAML messages, assertions, and metadata all commonly make use of the XML Signature KeyInfo construct, which expresses information about keys and certificates used in signing or encrypting XML.
The Apache Santuario XML Security for C++ library contained code paths at risk of dereferencing null pointers when processing various kinds of malformed KeyInfo hints typically found in signed or encrypted XML. The usual effect is a crash, and in the case of the Shibboleth SP software, a crash in the shibd daemon, which prevents access to protected resources until the daemon is restarted.
One of the data structures that holds TCP segments uses an inefficient algorithm to reassemble the data. This causes the CPU time spent on segment processing to grow linearly with the number of segments in the reassembly queue.
An attacker who has the ability to send TCP traffic to a victim system can degrade the victim system's network performance and/or consume excessive CPU by exploiting the inefficiency of TCP reassembly handling, with relatively small bandwidth cost.

Remote Code Execution Vulnerability in GitLab Projects Import
Typo3 core team reports:
It has been discovered that TYPO3’s Salted Password system extension (which is a mandatory system component) is vulnerable to Authentication Bypass when using hashing methods which are related by PHP class inheritance. In standard TYPO3 core distributions stored passwords using the blowfish hashing algorithm can be overridden when using MD5 as the default hashing algorithm by just knowing a valid username. Per default the Portable PHP hashing algorithm (PHPass) is used which is not vulnerable.
Phar files (formerly known as "PHP archives") can act als self extracting archives which leads to the fact that source code is executed when Phar files are invoked. The Phar file format is not limited to be stored with a dedicated file extension - "bundle.phar" would be valid as well as "bundle.txt" would be. This way, Phar files can be obfuscated as image or text file which would not be denied from being uploaded and persisted to a TYPO3 installation. Due to a missing sanitization of user input, those Phar files can be invoked by manipulated URLs in TYPO3 backend forms. A valid backend user account is needed to exploit this vulnerability. In theory the attack vector would be possible in the TYPO3 frontend as well, however no functional exploit has been identified so far.
Failing to properly dissociate system related configuration from user generated configuration, the Form Framework (system extension "form") is vulnerable to SQL injection and Privilege Escalation. Basically instructions can be persisted to a form definition file that were not configured to be modified - this applies to definitions managed using the form editor module as well as direct file upload using the regular file list module. A valid backend user account as well as having system extension form activated are needed in order to exploit this vulnerability.
It has been discovered that the Form Framework (system extension "form") is vulnerable to Insecure Deserialization when being used with the additional PHP PECL package “yaml”, which is capable of unserializing YAML contents to PHP objects. A valid backend user account as well as having PHP setting "yaml.decode_php" enabled is needed to exploit this vulnerability.

The phpMyAdmin development team reports:
Summary
XSS in Designer feature
Description
A Cross-Site Scripting vulnerability was found in the Designer feature, where an attacker can deliver a payload to a user through a specially-crafted database name.
Severity
We consider this attack to be of moderate severity.
Summary
File inclusion and remote code execution attack
Description
A flaw has been discovered where an attacker can include (view and potentially execute) files on the server.
The vulnerability comes from a portion of code where pages are redirected and loaded within phpMyAdmin, and an improper test for whitelisted pages.
An attacker must be authenticated, except in these situations:
- $cfg['AllowArbitraryServer'] = true: attacker can specify any host he/she is already in control of, and execute arbitrary code on phpMyAdmin
- $cfg['ServerDefault'] = 0: this bypasses the login and runs the vulnerable code without any authentication
Severity
We consider this to be severe.
Mitigation factor
Configuring PHP with a restrictive `open_basedir` can greatly restrict an attacker's ability to view files on the server. Vulnerable systems should not be run with the phpMyAdmin directives $cfg['AllowArbitraryServer'] = true or $cfg['ServerDefault'] = 0
A subset of Intel processors can allow a local thread to infer data from another thread through a speculative execution side channel when Lazy FPU state restore is used.
Any local thread can potentially read FPU state information from other threads running on the host. This could include cryptographic keys when the AES-NI CPU feature is present.

Node.js reports:
Denial of Service Vulnerability in HTTP/2 (CVE-2018-7161)
All versions of 8.x and later are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node server providing an http2 server to crash. This can be accomplished by interacting with the http2 server in a manner that triggers a cleanup bug where objects are used in native code after they are no longer available. This has been addressed by updating the http2 implementation. Thanks to Jordan Zebor at F5 Networks for reporting this issue.
Denial of Service, nghttp2 dependency (CVE-2018-1000168)
All versions of 9.x and later are vulnerable and the severity is HIGH. Under certain conditions, a malicious client can trigger an uninitialized read (and a subsequent segfault) by sending a malformed ALTSVC frame. This has been addressed through an by updating nghttp2.
Denial of Service Vulnerability in TLS (CVE-2018-7162)
All versions of 9.x and later are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node process which provides an http server supporting TLS server to crash. This can be accomplished by sending duplicate/unexpected messages during the handshake. This vulnerability has been addressed by updating the TLS implementation. Thanks to Jordan Zebor at F5 Networks all of his help investigating this issue with the Node.js team.
Memory exhaustion DoS on v9.x (CVE-2018-7164)
Versions 9.7.0 and later are vulnerable and the severity is MEDIUM. A bug introduced in 9.7.0 increases the memory consumed when reading from the network into JavaScript using the net.Socket object directly as a stream. An attacker could use this cause a denial of service by sending tiny chunks of data in short succession. This vulnerability was restored by reverting to the prior behaviour.
Calls to Buffer.fill() and/or Buffer.alloc() may hang (CVE-2018-7167)
Calling Buffer.fill() or Buffer.alloc() with some parameters can lead to a hang which could result in a Denial of Service. In order to address this vulnerability, the implementations of Buffer.alloc() and Buffer.fill() were updated so that they zero fill instead of hanging in these cases.
Jason A. Donenfeld reports:
Markus Brinkmann discovered that [the] parsing of gpg command line output with regexes isn't anchored to the beginning of the line, which means an attacker can generate a malicious key that simply has the verification string as part of its username.
This has a number of nasty consequences:
- an attacker who manages to write into your ~/.password-store and also inject a malicious key into your keyring can replace your .gpg-id key and have your passwords encrypted under additional keys;
- if you have extensions enabled (disabled by default), an attacker who manages to write into your ~/.password-store and also inject a malicious key into your keyring can replace your extensions and hence execute code.
GnuPG reports:
Mitigate a local side-channel attack on ECDSA signature as described in the white paper "Return on the Hidden Number Problem".
The OpenSSL project reports:
During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack.
The Asterisk project reports:
When endpoint specific ACL rules block a SIP request they respond with a 403 forbidden. However, if an endpoint is not identified then a 401 unauthorized response is sent. This vulnerability just discloses which requests hit a defined endpoint. The ACL rules cannot be bypassed to gain access to the disclosed endpoints.
The Asterisk project reports:
When connected to Asterisk via TCP/TLS if the client abruptly disconnects, or sends a specially crafted message then Asterisk gets caught in an infinite loop while trying to read the data stream. Thus rendering the system as unusable.

Corelight reports:
Bro 2.5.4 primarily fixes security issues
Multiple fixes and improvements to BinPAC generated code related to array parsing, with potential impact to all Bro's BinPAC-generated analyzers in the form of buffer over-reads or other invalid memory accesses depending on whether a particular analyzer incorrectly assumed that the evaulated-array-length expression is actually the number of elements that were parsed out from the input.
The NCP analyzer (not enabled by default and also updated to actually work with newer Bro APIs in the release) performed a memory allocation based directly on a field in the input packet and using signed integer storage. This could result in a signed integer overflow and memory allocations of negative or very large size, leading to a crash or memory exhaustion. The new NCP::max_frame_size tuning option now limits the maximum amount of memory that can be allocated.
The Git community reports:
Insufficient validation of submodule names
The Git community reports:
- In affected versions of Git, code to sanity-check pathnames on NTFS can result in reading out-of-bounds memory.
- In affected versions of Git, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs "git clone --recurse-submodules" because submodule "names" are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with "../" in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.

strongSwan security team reports:
- A denial-of-service vulnerability in the IKEv2 key derivation was fixed if the openssl plugin is used in FIPS mode and HMAC-MD5 is negotiated as PRF (which is not FIPS-compliant). So this should only affect very specific setups, but in such configurations all strongSwan versions since 5.0.1 may be affected.
- A denial-of-service vulnerability in the stroke plugin was fixed. When reading a message from the socket the plugin did not check the received length. Unless a group is configured, root privileges are required to access that socket, so in the default configuration this shouldn't be an issue, but all strongSwan versions may be affected.

ISC reports:
An error in zone database reference counting can lead to an assertion failure if a server which is running an affected version of BIND attempts several transfers of a slave zone in quick succession.
A problem with the implementation of the new serve-stale feature in BIND 9.12 can lead to an assertion failure in rbtdb.c, even when stale-answer-enable is off. Additionally, problematic interaction between the serve-stale feature and NSEC aggressive negative caching can in some cases cause undesirable behavior from named, such as a recursion loop or excessive logging.
cURL security problems:
CVE-2018-1000300: FTP shutdown response buffer overflow
curl might overflow a heap based memory buffer when closing down an FTP connection with very long server command replies.
When doing FTP transfers, curl keeps a spare "closure handle" around internally that will be used when an FTP connection gets shut down since the original curl easy handle is then already removed.
FTP server response data that gets cached from the original transfer might then be larger than the default buffer size (16 KB) allocated in the "closure handle", which can lead to a buffer overwrite. The contents and size of that overwrite is controllable by the server.
This situation was detected by an assert() in the code, but that was of course only preventing bad stuff in debug builds. This bug is very unlikely to trigger with non-malicious servers.
We are not aware of any exploit of this flaw.
CVE-2018-1000301: RTSP bad headers buffer over-read
curl can be tricked into reading data beyond the end of a heap based buffer used to store downloaded content.
When servers send RTSP responses back to curl, the data starts out with a set of headers. curl parses that data to separate it into a number of headers to deal with those appropriately and to find the end of the headers that signal the start of the "body" part.
The function that splits up the response into headers is called Curl_http_readwrite_headers() and in situations where it can't find a single header in the buffer, it might end up leaving a pointer pointing into the buffer instead of to the start of the buffer which then later on may lead to an out of buffer read when code assumes that pointer points to a full buffer size worth of memory to use.
This could potentially lead to information leakage but most likely a crash/denial of service for applications if a server triggers this flaw.
We are not aware of any exploit of this flaw.

The agent to master security subsystem ensures that the Jenkins master is protected from maliciously configured agents. A path traversal vulnerability allowed agents to escape whitelisted directories to read and write to files they should not be able to access.
Black Duck Hub Plugin's API endpoint was affected by an XML External Entity (XXE) processing vulnerability. This allowed an attacker with Overall/Read access to have Jenkins parse a maliciously crafted file that uses external entities for extraction of secrets from the Jenkins master, server-side request forgery, or denial-of-service attacks.
Several other lower severity issues were reported, see reference url for details.

Adobe reports:
- This update resolves a type confusion vulnerability that could lead to arbitrary code execution (CVE-2018-4944).
The MOV SS and POP SS instructions inhibit debug exceptions until the instruction boundary following the next instruction. If that instruction is a system call or similar instruction that transfers control to the operating system, the debug exception will be handled in the kernel context instead of the user context.
An authenticated local attacker may be able to read sensitive data in kernel memory, control low-level operating system functions, or may panic the system.

Summary
CSRF vulnerability allowing arbitrary SQL execution
Description
By deceiving a user to click on a crafted URL, it is possible for an attacker to execute arbitrary SQL commands.
Severity
We consider this vulnerability to be critical.
The Drupal security team reports:
CKEditor, a third-party JavaScript library included in Drupal core, has fixed a cross-site scripting (XSS) vulnerability. The vulnerability stemmed from the fact that it was possible to execute XSS inside CKEditor when using the image2 plugin (which Drupal 8 core also uses).
The OpenSSL project reports:
The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key.
Drupal Security Team reports:
CVE-2018-7600: Drupal before 7.58, 8.x before 8.3.9, 8.4.x before 8.4.6, and 8.5.x before 8.5.1 allows remote attackers to execute arbitrary code because of an issue affecting multiple subsystems with default or common module configurations.
perldelta:
CVE-2018-6797: heap-buffer-overflow (WRITE of size 1) in S_regatom (regcomp.c)
A crafted regular expression could cause a heap buffer write overflow, with control over the bytes written. [perl #132227]
CVE-2018-6798: Heap-buffer-overflow in Perl__byte_dump_string (utf8.c)
Matching a crafted locale dependent regular expression could cause a heap buffer read overflow and potentially information disclosure. [perl #132063]
CVE-2018-6913: heap-buffer-overflow in S_pack_rec
pack() could cause a heap buffer write overflow with a large item count. [perl #131844]
Robert Foggia via NetBSD GNATS reports:
The ipsec-tools racoon daemon contains a remotely exploitable computational complexity attack when parsing and storing isakmp fragments. The implementation permits a remote attacker to exhaust computational resources on the remote endpoint by repeatedly sending isakmp fragment packets in a particular order such that the worst-case computational complexity is realized in the algorithm utilized to determine if reassembly of the fragments can take place.
nghttp2 blog:
If ALTSVC frame is received by libnghttp2 and it is larger than it can accept, the pointer field which points to ALTSVC frame payload is left NULL. Later libnghttp2 attempts to access another field through the pointer, and gets segmentation fault.
ALTSVC frame is defined by RFC 7838.
The largest frame size libnghttp2 accept is by default 16384 bytes.
Receiving ALTSVC frame is disabled by default. Application has to enable it explicitly by calling nghttp2_option_set_builtin_recv_extension_type(opt, NGHTTP2_ALTSVC).
Transmission of ALTSVC is always enabled, and it does not cause this vulnerability.
ALTSVC frame is expected to be sent by server, and received by client as defined in RFC 7838.
Client and server are both affected by this vulnerability if the reception of ALTSVC frame is enabled. As written earlier, it is useless to enable reception of ALTSVC frame on server side. So, server is generally safe unless application accidentally enabled the reception of ALTSVC frame.
Upstream reports:
This update primarily fixes a recently discovered IMAP-cmd-injection vulnerability caused by insufficient input validation within the archive plugin. Details about the vulnerability are published under CVE-2018-9846.
Jenkins developers report:
The Jenkins CLI sent different error responses for commands with view and agent arguments depending on the existence of the specified views or agents to unauthorized users. This allowed attackers to determine whether views or agents with specified names exist.
The Jenkins CLI now returns the same error messages to unauthorized users independent of the existence of specified view or agent names
Some JavaScript confirmation dialogs included the item name in an unsafe manner, resulting in a possible cross-site scripting vulnerability exploitable by users with permission to create or configure items.
JavaScript confirmation dialogs that include the item name now properly escape it, so it can be safely displayed.
Adobe reports:
- This update resolves a use-after-free vulnerability that could lead to remote code execution (CVE-2018-4932).
- This update resolves out-of-bounds read vulnerabilities that could lead to information disclosure (CVE-2018-4933, CVE-2018-4934).

- This update resolves a heap overflow vulnerability that could lead to information disclosure (CVE-2018-4936).
GitLab reports:
Confidential issue comments in Slack, Mattermost, and webhook integrations.
Persistent XSS in milestones data-milestone-id.
Persistent XSS in filename of merge request.
The length field of the option header does not count the size of the option header itself. This causes a problem when the length is zero, the count is then incremented by zero, which causes an infinite loop.
In addition there are pointer/offset mistakes in the handling of IPv4 options.
A remote attacker who is able to send an arbitrary packet, could cause the remote target machine to crash.
Insufficient validation of user-provided font parameters can result in an integer overflow, leading to the use of arbitrary kernel memory as glyph data. Characters that reference this data can be displayed on the screen, effectively disclosing kernel memory.
Unprivileged users may be able to access privileged kernel data.
Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way; for example, a terminal buffer might include a user-entered password.

Ruby news:
CVE-2017-17742: HTTP response splitting in WEBrick
If a script accepts an external input and outputs it without modification as a part of HTTP responses, an attacker can use newline characters to deceive the clients that the HTTP response header is stopped at there, and can inject fake HTTP responses after the newline characters to show malicious contents to the clients.
CVE-2018-6914: Unintentional file and directory creation with directory traversal in tempfile and tmpdir
Dir.mktmpdir method introduced by tmpdir library accepts the prefix and the suffix of the directory which is created as the first parameter. The prefix can contain relative directory specifiers "../", so this method can be used to target any directory. So, if a script accepts an external input as the prefix, and the targeted directory has inappropriate permissions or the ruby process has inappropriate privileges, the attacker can create a directory or a file at any directory.
CVE-2018-8777: DoS by large request in WEBrick
If an attacker sends a large request which contains huge HTTP headers, WEBrick try to process it on memory, so the request causes the out-of-memory DoS attack.
CVE-2018-8778: Buffer under-read in String#unpack
String#unpack receives format specifiers as its parameter, and can be specified the position of parsing the data by the specifier @. If a big number is passed with @, the number is treated as the negative value, and out-of-buffer read is occurred. So, if a script accepts an external input as the argument of String#unpack, the attacker can read data on heaps.
CVE-2018-8779: Unintentional socket creation by poisoned NUL byte in UNIXServer and UNIXSocket
UNIXServer.open accepts the path of the socket to be created at the first parameter. If the path contains NUL (\0) bytes, this method recognize that the path is completed before the NUL bytes. So, if a script accepts an external input as the argument of this method, the attacker can make the socket file in the unintentional path. And, UNIXSocket.open also accepts the path of the socket to be created at the first parameter without checking NUL bytes like UNIXServer.open. So, if a script accepts an external input as the argument of this method, the attacker can accepts the socket file in the unintentional path.
CVE-2018-8780: Unintentional directory traversal by poisoned NUL byte in Dir
Dir.open, Dir.new, Dir.entries and Dir.empty? accept the path of the target directory as their parameter. If the parameter contains NUL (\0) bytes, these methods recognize that the path is completed before the NUL bytes. So, if a script accepts an external input as the argument of these methods, the attacker can make the unintentional directory traversal.
Node.js reports:
Node.js Inspector DNS rebinding vulnerability (CVE-2018-7160)
Node.js 6.x and later include a debugger protocol (also known as "inspector") that can be activated by the --inspect and related command line flags. This debugger service was vulnerable to a DNS rebinding attack which could be exploited to perform remote code execution.
'path' module regular expression denial of service (CVE-2018-7158)
The 'path' module in the Node.js 4.x release line contains a potential regular expression denial of service (ReDoS) vector. The code in question was replaced in Node.js 6.x and later so this vulnerability only impacts all versions of Node.js 4.x.
Spaces in HTTP Content-Length header values are ignored (CVE-2018-7159)
The HTTP parser in all current versions of Node.js ignores spaces in the Content-Length header, allowing input such as Content-Length: 1 2 to be interpreted as having a value of 12. The HTTP specification does not allow for spaces in the Content-Length value and the Node.js HTTP parser has been brought into line on this particular difference.
The WebKit team reports many vulnerabilities.

The OpenSSL project reports:
- Constructed ASN.1 types with a recursive definition could exceed the stack (CVE-2018-0739)
Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe.- rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738)
There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. This only affects processors that support the AVX2 but not ADX extensions like Intel Haswell (4th generation).
GitLab reports:

MITRE reports:
SQLite databases whose schema is corrupted using a CREATE TABLE AS statement could cause a NULL pointer dereference, related to build.c and prepare.c.
Sanitize release:
Fixed an HTML injection vulnerability that could allow XSS.
When Sanitize <= 4.6.2 is used in combination with libxml2 >= 2.9.2, a specially crafted HTML fragment can cause libxml2 to generate improperly escaped output, allowing non-whitelisted attributes to be used on whitelisted elements.
Sanitize now performs additional escaping on affected attributes to prevent this.
GitHub issue:
This issue has been created for public disclosure of an XSS / code injection vulnerability that was responsibly reported by the Shopify Application Security Team.
Loofah allows non-whitelisted attributes to be present in sanitized output when input with specially-crafted HTML fragments.
MITRE reports:
In Jupyter Notebook before 5.4.1, a maliciously forged notebook file can bypass sanitization to execute JavaScript in the notebook context. Specifically, invalid HTML is 'fixed' by jQuery after sanitization, making it dangerous.
Florian Grunow reports:
An attacker able to exploit this vulnerability can extract files of the server the application is running on. This may include configuration files, log files and additionally all files that are readable for all users on the system. This issue is post-authentication. That means an attacker would need valid credentials for the application to log in or needs to exploit an additional vulnerability of which we are not aware of at this point of time.
An attacker would also be able to delete files on the system, if the user running the application has the rights to do so.
Does this issue affect me?
Likely yes, if you are using Squirrelmail. We checked the latest development version, which is 1.5.2-svn and the latest version available for download at this point of time, 1.4.22. Both contain the vulnerable code.
SchedMD reports:
Several issues were discovered with incomplete sanitization of user-provided text strings, which could potentially lead to SQL injection attacks against SlurmDBD itself. Such exploits could lead to a loss of accounting data, or escalation of user privileges on the cluster.

In Xiph.Org libvorbis 1.3.5, an out-of-bounds array read vulnerability exists in the function mapping0_forward() in mapping0.c, which may lead to DoS when operating on a crafted audio file with vorbis_analysis().
The Mozilla Foundation reports:
CVE-2018-5146: Out of bounds memory write in libvorbis
An out of bounds memory write while processing Vorbis audio data was reported through the Pwn2Own contest.
CVE-2018-5147: Out of bounds memory write in libtremor
The libtremor library has the same flaw as CVE-2018-5146. This library is used by Firefox in place of libvorbis on Android and ARM platforms.
Theodore Y. Ts'o reports:
Fixed some potential buffer overrun bugs in the blkid library and in the fsck program.
A number of issues relating to speculative execution were found last year and publicly announced January 3rd. Two of these, known as Meltdown and Spectre V2, are addressed here.
CVE-2017-5754 (Meltdown) - ------------------------
This issue relies on an affected CPU speculatively executing instructions beyond a faulting instruction. When this happens, changes to architectural state are not committed, but observable changes may be left in micro- architectural state (for example, cache). This may be used to infer privileged data.
CVE-2017-5715 (Spectre V2) - --------------------------
Spectre V2 uses branch target injection to speculatively execute kernel code at an address under the control of an attacker.
An attacker may be able to read secret data from the kernel or from a process when executing untrusted code (for example, in a web browser).
Due to a lack of strict checking, an attacker from a trusted host can send a specially constructed IP packet that may lead to a system crash.
Additionally, a use-after-free vulnerability in the AH handling code could cause unpredictable results.
Access to out of bounds or freed mbuf data can lead to a kernel panic or other unpredictable results.
Adobe reports:
- This update resolves a use-after-free vulnerability that could lead to remote code execution (CVE-2018-4919).
- This update resolves a type confusion vulnerability that could lead to remote code execution (CVE-2018-4920).

On a Samba 4 AD DC any authenticated user can change other user's passwords over LDAP, including the passwords of administrative users and service accounts.
Simon Butcher reports:
- When the truncated HMAC extension is enabled and CBC is used, sending a malicious application packet can be used to selectively corrupt 6 bytes on the peer's heap, potentially leading to a crash or remote code execution. This can be triggered remotely from either side in both TLS and DTLS.
- When RSASSA-PSS signature verification is enabled, sending a maliciously constructed certificate chain can be used to cause a buffer overflow on the peer's stack, potentially leading to crash or remote code execution. This can be triggered remotely from either side in both TLS and DTLS.

ISC reports:
Failure to properly bounds check a buffer used for processing DHCP options allows a malicious server (or an entity masquerading as a server) to cause a buffer overflow (and resulting crash) in dhclient by sending a response containing a specially constructed options section.
A malicious client which is allowed to send very large amounts of traffic (billions of packets) to a DHCP server can eventually overflow a 32-bit reference counter, potentially causing dhcpd to crash.

Strongswan Release Notes reports:
Fixed a DoS vulnerability in the parser for PKCS#1 RSASSA-PSS signatures that was caused by insufficient input validation. One of the configurable parameters in algorithm identifier structures for RSASSA-PSS signatures is the mask generation function (MGF). Only MGF1 is currently specified for this purpose. However, this in turn takes itself a parameter that specifies the underlying hash function. strongSwan's parser did not correctly handle the case of this parameter being absent, causing an undefined data read. his vulnerability has been registered as CVE-2018-6459.
Laurent Delosieres, Secunia Research at Flexera Software reports:
Secunia Research has discovered a vulnerability in libsndfile, which can be exploited by malicious people to disclose potentially sensitive information.

The Apache Software Foundation reports:
Security constraints defined by annotations of Servlets were only applied once a Servlet had been loaded. Because security constraints defined in this way apply to the URL pattern and any URLs below that point, it was possible - depending on the order Servlets were loaded - for some security constraints not to be applied. This could have exposed resources to users who were not authorised to access them.
The URL pattern of "" (the empty string) which exactly maps to the context root was not correctly handled when used as part of a security constraint definition. This caused the constraint to be ignored. It was, therefore, possible for unauthorised users to gain access to web application resources that should have been protected. Only security constraints with a URL pattern of the empty string were affected.
Shibboleth consortium reports:
Shibboleth SP software vulnerable to additional data forgery flaws
The XML processing performed by the Service Provider software has been found to be vulnerable to new flaws similar in nature to the one addressed in an advisory last month.
These bugs involve the use of other XML constructs rather than entity references, and therefore required additional mitigation once discovered. As with the previous issue, this flaw allows for changes to an XML document that do not break a digital signature but can alter the user data passed through to applications behind the SP and result in impersonation attacks and exposure of protected information.
As before, the use of XML Encryption is a significant mitigation, but we have not dismissed the possibility that attacks on the Response "envelope" may be possible, in both the original and this new case. No actual attacks of this nature are known, so deployers should prioritize patching systems that expect to handle unencrypted SAML assertions.
An updated version of XMLTooling-C (V1.6.4) is available that protects against these new attacks, and should help prevent similar vulnerabilities in the future.
Unlike the previous case, these bugs are NOT prevented by any existing Xerces-C parser version on any platform and cannot be addressed by any means other than the updated XMLTooling-C library.
The Service Provider software relies on a generic XML parser to process SAML responses and there are limitations in older versions of the parser that make it impossible to fully disable Document Type Definition (DTD) processing.
Through addition/manipulation of a DTD, it's possible to make changes to an XML document that do not break a digital signature but are mishandled by the SP and its libraries. These manipulations can alter the user data passed through to applications behind the SP and result in impersonation attacks and exposure of protected information.
While newer versions of the xerces-c3 parser are configured by the SP into disallowing the use of a DTD via an environment variable, this feature is not present in the xerces-c3 parser before version 3.1.4, so an additional fix is being provided now that an actual DTD exploit has been identified. Xerces-c3-3.1.4 was committed to the ports tree already on 2016-07-26.

Hank Leininger reports:
Bugs in Git, Subversion, and Mercurial were just announced and patched which allowed arbitrary local command execution if a malicious name was used for the remote server, such as starting with - to pass options to the ssh client: git clone ssh://-oProxyCommand=some-command... CVS has a similar problem with the -d option:
Tested vanilla CVS 1.12.13, and Gentoo CVS 1.12.12-r11.
LibreOffice reports:
LibreOffice Calc supports a WEBSERVICE function to obtain data by URL. Vulnerable versions of LibreOffice allow WEBSERVICE to take a local file URL (e.g file://) which can be used to inject local files into the spreadsheet without warning the user. Subsequent formulas can operate on that inserted data and construct a remote URL whose path leaks the local data to a remote attacker.
In later versions of LibreOffice without this flaw, WEBSERVICE has now been limited to accessing http and https URLs along with bringing WEBSERVICE URLs under LibreOffice Calc's link management infrastructure.
Note: This vulnerability has been identified upstream as CVE-2018-1055, but NVD/Mitre are advising it's a reservation duplicate of CVE-2018-6871 which should be used instead.
Louis Dion-Marcil reports:
Due to incorrect pointer handling Squid is vulnerable to denial of service attack when processing ESI responses.
This problem allows a remote server delivering certain ESI response syntax to trigger a denial of service for all clients accessing the Squid service.
Due to unrelated changes Squid-3.5 has become vulnerable to some regular ESI server responses also triggering this issue.
This problem is limited to the Squid custom ESI parser. Squid built to use libxml2 or libexpat XML parsers do not have this problem.
Due to incorrect pointer handling Squid is vulnerable to denial of service attack when processing ESI responses or downloading intermediate CA certificates.
This problem allows a remote client delivering certain HTTP requests in conjunction with certain trusted server responses to trigger a denial of service for all clients accessing the Squid service.

Mitre reports:
bchunk 1.2.0 and 1.2.1 vulnerable to a heap-based buffer overflow and crash when processing a malformed CUE (.cue) file.
Uwsgi developers report:
It was discovered that the uwsgi_expand_path function in utils.c in Unbit uWSGI, an application container server, has a stack-based buffer overflow via a large directory length that can cause a denial-of-service (application crash) or stack corruption.
Python issue:
There is a possible integer overflow in PyString_DecodeEscape function of the file stringobject.c, which can be abused to gain a heap overflow, possibly leading to arbitrary code execution.
MITRE reports:
JSONRPC vulnerability
X-cela reports:
Calls into build_benocde that use %zu could crash on 64 bit machines due to the size change of size_t. Someone can force READ_ENC_IA to fail allowing an internal_error to be thrown and bring down the client.
Exim developers report:
There is a buffer overflow in base64d(), if some pre-conditions are met. Using a handcrafted message, remote code execution seems to be possible.
MITRE reports:
Insufficient exception handling in the method NCompress::NRar3::CDecoder::Code of 7-Zip before 18.00 and p7zip can lead to multiple memory corruptions within the PPMd code, alows remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive.
MITRE reports:
Heap-based buffer overflow in the NCompress::NShrink::CDecoder::CodeReal method in 7-Zip before 18.00 and p7zip allows remote attackers to cause a denial of service (out-of-bounds write) or potentially execute arbitrary code via a crafted ZIP archive.
mpv developers report:
mpv through 0.28.0 allows remote attackers to execute arbitrary code via a crafted web site, because it reads HTML documents containing VIDEO elements, and accepts arbitrary URLs in a src attribute without a protocol whitelist in player/lua/ytdl_hook.lua. For example, an av://lavfi:ladspa=file= URL signifies that the product should call dlopen on a shared object file located at an arbitrary local pathname. The issue exists because the product does not consider that youtube-dl can provide a potentially unsafe URL.
Mark Sapiro reports:
An XSS vulnerability in the user options CGI could allow a crafted URL to execute arbitrary javascript in a user's browser. A related issue could expose information on a user's options page without requiring login.
The PostgreSQL project reports:

Django release notes:
CVE-2018-6188: Information leakage in AuthenticationForm
A regression in Django 1.11.8 made AuthenticationForm run its confirm_login_allowed() method even if an incorrect password is entered. This can leak information about a user, depending on what messages confirm_login_allowed() raises. If confirm_login_allowed() isn't overridden, an attacker enter an arbitrary username and see if that user has been set to is_active=False. If confirm_login_allowed() is overridden, more sensitive details could be leaked.
This issue is fixed with the caveat that AuthenticationForm can no longer raise the "This account is inactive." error if the authentication backend rejects inactive users (the default authentication backend, ModelBackend, has done that since Django 1.10). This issue will be revisited for Django 2.1 as a fix to address the caveat will likely be too invasive for inclusion in older versions.

A stack-based buffer overflow within GNOME gcab through 0.7.4 can be exploited by malicious attackers to cause a crash or, potentially, execute arbitrary code via a crafted .cab file.
Pedro Sampaio reports:
A flaw was found in dovecot 2.0 up to 2.2.33 and 2.3.0. A abort of SASL authentication results in a memory leak in Dovecot auth client used by login processes. The leak has impact in high performance configuration where same login processes are reused and can cause the process to crash due to memory exhaustion.
The cURL project reports:
libcurl 7.1 through 7.57.0 might accidentally leak authentication data to third parties. When asked to send custom headers in its HTTP requests, libcurl will send that set of headers first to the host in the initial URL but also, if asked to follow redirects and a 30X HTTP response code is returned, to the host mentioned in URL in the `Location:` response header value. Sending the same set of headers to subsequest hosts is in particular a problem for applications that pass on custom `Authorization:` headers, as this header often contains privacy sensitive information or data that could allow others to impersonate the libcurl-using client's request.

Google Project Zero reports:
The transmission bittorrent client uses a client/server architecture, the user interface is the client which communicates to the worker daemon using JSON RPC requests.
As with all HTTP RPC schemes like this, any website can send requests to the daemon listening on localhost with XMLHttpRequest(), but the theory is they will be ignored because clients must prove they can read and set a specific header, X-Transmission-Session-Id. Unfortunately, this design doesn't work because of an attack called "DNS rebinding". Any website can simply create a dns name that they are authorized to communicate with, and then make it resolve to localhost.
Exploitation is simple, you could set script-torrent-done-enabled and run any command, or set download-dir to /home/user/ and then upload a torrent for .bashrc.
Shibboleth consortium reports:
Shibboleth SP software vulnerable to forged user attribute data
The Service Provider software relies on a generic XML parser to process SAML responses and there are limitations in older versions of the parser that make it impossible to fully disable Document Type Definition (DTD) processing.
Through addition/manipulation of a DTD, it's possible to make changes to an XML document that do not break a digital signature but are mishandled by the SP and its libraries. These manipulations can alter the user data passed through to applications behind the SP and result in impersonation attacks and exposure of protected information.
While newer versions of the xerces-c3 parser are configured by the SP into disallowing the use of a DTD via an environment variable, this feature is not present in the xerces-c3 parser before version 3.1.4, so an additional fix is being provided now that an actual DTD exploit has been identified. Xerces-c3-3.1.4 was committed to the ports tree already on 2016-07-26.
Adobe reports:

Mozilla Foundation reports:
Jann Horn of Google Project Zero Security reported that speculative execution performed by modern CPUs could leak information through a timing side-channel attack. Microsoft Vulnerability Research extended this attack to browser JavaScript engines and demonstrated that code on a malicious web page could read data from other web sites (violating the same-origin policy) or private data from the browser itself.
Since this new class of attacks involves measuring precise time intervals, as a parti al, short-term, mitigation we are disabling or reducing the precision of several time sources in Firefox. The precision of
performance.now()
has been reduced from 5μs to 20μs, and theSharedArrayBuffer
feature has been disabled because it can be used to construct a high-resolution timer.
OTRS reports:
An attacker who is logged into OTRS as an agent can request special URLs from OTRS which can lead to the execution of shell commands with the permissions of the web server user.
An attacker who is logged into OTRS as a customer can use the ticket search form to disclose internal article information of their customer tickets.
An attacker who is logged into OTRS as an agent can manipulate form parameters and execute arbitrary shell commands with the permissions of the OTRS or web server user.
An attacker can send a specially prepared email to an OTRS system. If this system has cookie support disabled, and a logged in agent clicks a link in this email, the session information could be leaked to external systems, allowing the attacker to take over the agent’s session.

Severity
We consider this vulnerability to be critical.
The Asterisk project reports:
A select set of SIP messages create a dialog in Asterisk. Those SIP messages must contain a contact header. For those messages, if the header was not present and using the PJSIP channel driver, it would cause Asterisk to crash. The severity of this vulnerability is somewhat mitigated if authentication is enabled. If authentication is enabled a user would have to first be authorized before reaching the crash point.
The MariaDB project reports:
Fixes for the following security vulnerabilities: CVE-2017-15365
Jeriko One reports:
The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a trailing '\0' character in an xattr name, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact by sending crafted data to the daemon.
The recv_files function in receiver.c in the daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, proceeds with certain file metadata updates before checking for a filename in the daemon_filter_list data structure, which allows remote attackers to bypass intended access restrictions.
The daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, does not check for fnamecmp filenames in the daemon_filter_list data structure (in the recv_files function in receiver.c) and also does not apply the sanitize_paths protection mechanism to pathnames found in "xname follows" strings (in the read_ndx_and_attrs function in rsync.c), which allows remote attackers to bypass intended access restrictions.
Etienne Stalmans from the Heroku product security team reports:
There is a command injection vulnerability in Net::FTP bundled with Ruby.
Net::FTP#get
,getbinaryfile
,gettextfile
,put
,putbinaryfile
, andputtextfile
useKernel#open
to open a local file. If thelocalfile
argument starts with the pipe character"|"
, the command following the pipe character is executed. The default value oflocalfile
isFile.basename(remotefile)
, so malicious FTP servers could cause arbitrary command execution.
Phusion reports:
The cPanel Security Team discovered a vulnerability in Passenger that allows users to list the contents of arbitrary files on the system. CVE-2017-16355 has been assigned to this issue.
the freedesktop.org project reports:
A non-privileged X client can instruct X server running under root to open any file by creating own directory with "fonts.dir", "fonts.alias" or any font file being a symbolic link to any other file in the system. X server will then open it. This can be issue with special files such as /dev/watchdog.
The freedesktop.org project reports:
If a pattern contains '?' character, any character in the string is skipped, even if it is '\0'. The rest of the matching then reads invalid memory.
Without the checks a malformed PCF file can cause the library to make atom from random heap memory that was behind the `strings` buffer. This may crash the process or leak information.
The freedesktop.org project reports:
It is possible to trigger heap overflows due to an integer overflow while parsing images and a signedness issue while parsing comments.
The integer overflow occurs because the chosen limit 0x10000 for dimensions is too large for 32 bit systems, because each pixel takes 4 bytes. Properly chosen values allow an overflow which in turn will lead to less allocated memory than needed for subsequent reads.
The signedness bug is triggered by reading the length of a comment as unsigned int, but casting it to int when calling the function XcursorCommentCreate. Turning length into a negative value allows the check against XCURSOR_COMMENT_MAX_LEN to pass, and the following addition of sizeof (XcursorComment) + 1 makes it possible to allocate less memory than needed for subsequent reads.
MITRE reports:
gozilla.c in GNU GLOBAL 4.8.6 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL.
The Jenkins project reports:
A race condition during Jenkins startup could result in the wrong order of execution of commands during initialization.
On Jenkins 2.81 and newer, including LTS 2.89.1, this could in rare cases (we estimate less than 20% of new instances) result in failure to initialize the setup wizard on the first startup.
There is a very short window of time after startup during which Jenkins may no longer show the "Please wait while Jenkins is getting ready to work" message, but Cross-Site Request Forgery (CSRF) protection may not yet be effective.
Node.js reports:
Data Confidentiality/Integrity Vulnerability - CVE-2017-15896
Node.js was affected by OpenSSL vulnerability CVE-2017-3737 in regards to the use of SSL_read() due to TLS handshake failure. The result was that an active network attacker could send application data to Node.js using the TLS or HTTP2 modules in a way that bypassed TLS authentication and encryption.
Uninitialized buffer vulnerability - CVE-2017-15897
Node.js had a bug in versions 8.X and 9.X which caused buffers to not be initialized when the encoding for the fill value did not match the encoding specified. For example, 'Buffer.alloc(0x100, "This is not correctly encoded", "hex");' The buffer implementation was updated such that the buffer will be initialized to all zeros in these cases.
Also included in OpenSSL update - CVE 2017-3738
Note that CVE 2017-3738 of OpenSSL-1.0.2 affected Node but it was low severity.

The Asterisk project reports:
If a compound RTCP packet is received containing more than one report (for example a Receiver Report and a Sender Report) the RTCP stack will incorrectly store report information outside of allocated memory potentially causing a crash.
libxml2 developers report:
The htmlParseTryOrFinish function in HTMLparser.c in libxml2 2.9.4 allows attackers to cause a denial of service (buffer over-read) or information disclosure.
A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash.
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a stack-based buffer overflow. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. At the end of the routine, the function may strcat two more characters without checking whether the current strlen(buf) + 2 < size. This vulnerability causes programs that use libxml2, such as PHP, to crash.
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictComputeFastKey function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for libxml2 Bug 759398.
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictAddString function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for CVE-2016-1839.
Invoking SSL_read()/SSL_write() while in an error state causes data to be passed without being decrypted/encrypted directly from the SSL/TLS record layer.
In order to exploit this issue an application bug would have to be present that resulted in a call to SSL_read()/SSL_write() being issued after having already received a fatal error. [CVE-2017-3737]
There is an overflow bug in the x86_64 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. This only affects processors that support the AVX2 but not ADX extensions like Intel Haswell (4th generation). [CVE-2017-3738] This bug only affects FreeBSD 11.x.
Applications with incorrect error handling may inappropriately pass unencrypted data. [CVE-2017-3737]
Mishandling of carry propagation will produce incorrect output, and make it easier for a remote attacker to obtain sensitive private-key information. No EC algorithms are affected and analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely.
Attacks against DH1024 are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. However, for an attack on TLS to be meaningful, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701. [CVE-2017-3738]

The OpenSSL project reports:
- Read/write after SSL object in error state (CVE-2017-3737)
OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the explicit handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake fails then a fatal error will be returned in the initial function call. If SSL_read()/SSL_write() is subsequently called by the application for the same SSL object then it will succeed and the data is passed without being decrypted/encrypted directly from the SSL/TLS record layer.- rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738)
There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH1024 are considered just feasible, because most of the work necessary to deduce information about a private key may be performed offline.

If an X.509 certificate has a malformed IPAddressFamily extension, OpenSSL could do a one-byte buffer overread. [CVE-2017-3735]
There is a carry propagating bug in the x86_64 Montgomery squaring procedure. This only affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen. [CVE-2017-3736] This bug only affects FreeBSD 11.x.
Application using OpenSSL may display erroneous certificate in text format. [CVE-2017-3735]
Mishandling of carry propagation will produce incorrect output, and make it easier for a remote attacker to obtain sensitive private-key information. No EC algorithms are affected, analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely.
Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. [CVE-2017-3736]
The kernel does not properly clear the memory of the kld_file_stat structure before filling the data. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information from the kernel stack is possible.
Some bytes from the kernel stack can be observed in userspace.
Named paths are globally scoped, meaning a process located in one jail can read and modify the content of POSIX shared memory objects created by a process in another jail or the host system.
A malicious user that has access to a jailed system is able to abuse shared memory by injecting malicious content in the shared memory region. This memory region might be executed by applications trusting the shared memory, like Squid.
This issue could lead to a Denial of Service or local privilege escalation.
Not all information in the struct ptrace_lwpinfo is relevant for the state of any thread, and the kernel does not fill the irrelevant bytes or short strings. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information of the kernel stack of the thread is possible from the debugger.
Some bytes from the kernel stack of the thread using ptrace(PT_LWPINFO) call can be observed in userspace.
A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys.
Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used.

Exim developers team reports:
The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to cause a denial of service (infinite loop and stack exhaustion) via vectors involving BDAT commands and an improper check for a '.' character signifying the end of the content, related to the bdat_getc function.

The scp_v0s_accept function in the session manager uses an untrusted integer as a write length, which allows local users to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted input stream.
The cURL project reports:
- NTLM buffer overflow via integer overflow (CVE-2017-8816)
libcurl contains a buffer overrun flaw in the NTLM authentication code. The internal function Curl_ntlm_core_mk_ntlmv2_hash sums up the lengths of the user name + password (= SUM) and multiplies the sum by two (= SIZE) to figure out how large storage to allocate from the heap.- FTP wildcard out of bounds read (CVE-2017-8817)
libcurl contains a read out of bounds flaw in the FTP wildcard function. libcurl's FTP wildcard matching feature, which is enabled with the CURLOPT_WILDCARDMATCH option can use a built-in wildcard function or a user provided one. The built-in wildcard function has a flaw that makes it not detect the end of the pattern string if it ends with an open bracket ([) but instead it will continue reading the heap beyond the end of the URL buffer that holds the wildcard.- SSL out of buffer access (CVE-2017-8818)
libcurl contains an out boundary access flaw in SSL related code. When allocating memory for a connection (the internal struct called connectdata), a certain amount of memory is allocated at the end of the struct to be used for SSL related structs. Those structs are used by the particular SSL library libcurl is built to use. The application can also tell libcurl which specific SSL library to use if it was built to support more than one.

The Internet2 community reports:
The Shibboleth Service Provider software includes a MetadataProvider plugin with the plugin type "Dynamic" to obtain metadata on demand from a query server, in place of the more typical mode of downloading aggregates separately containing all of the metadata to load.
All the plugin types rely on MetadataFilter plugins to perform critical security checks such as signature verification, enforcement of validity periods, and other checks specific to deployments.
Due to a coding error, the "Dynamic" plugin fails to configure itself with the filters provided to it and thus omits whatever checks they are intended to perform, which will typically leave deployments vulnerable to active attacks involving the substitution of metadata if the network path to the query service is compromised.

Jenkins developers report:
Jenkins stores metadata related to people, which encompasses actual user accounts, as well as users appearing in SCM, in directories corresponding to the user ID on disk. These directories used the user ID for their name without additional escaping. This potentially resulted in a number of problems.
Autocompletion suggestions for text fields were not escaped, resulting in a persisted cross-site scripting vulnerability if the source for the suggestions allowed specifying text that includes HTML metacharacters like less-than and greater-than characters.
The Asterisk project reports:
A memory leak occurs when an Asterisk pjsip session object is created and that call gets rejected before the session itself is fully established. When this happens the session object never gets destroyed. This then leads to file descriptors and RTP ports being leaked as well.
The Asterisk project reports:
No size checking is done when setting the user field for Party B on a CDR. Thus, it is possible for someone to use an arbitrarily large string and write past the end of the user field storage buffer. The earlier AST-2017-001 advisory for the CDR user field overflow was for the Party A buffer.
The Asterisk project reports:
By carefully crafting invalid values in the Cseq and the Via header port, pjprojects packet parsing code can create strings larger than the buffer allocated to hold them. This will usually cause Asterisk to crash immediately. The packets do not have to be authenticated.

Open redirect in repository git redirects
Eric Rafaloff via HackerOne reported that GitLab was vulnerable to an open redirect vulnerability when redirecting requests for repository names that include the git extension. GitLab was not properly removing dangerous parameters from the params field before redirecting which could allow an attacker to redirect users to arbitrary hosts.
Username changes could leave repositories behind
An internal code review discovered that a bug in the code that moves repositories during a username change could potentially leave behind projects, allowing an attacker who knows the previous username to potentially steal the contents of repositories on instances that are not configured with hashed namespaces.
The Apache Openofffice project reports:
CVE-2017-3157: Arbitrary file disclosure in Calc and Writer
By exploiting the way OpenOffice renders embedded objects, an attacker could craft a document that allows reading in a file from the user's filesystem. Information could be retrieved by the attacker by, e.g., using hidden sections to store the information, tricking the user into saving the document and convincing the user to sent the document back to the attacker.
The vulnerability is mitigated by the need for the attacker to know the precise file path in the target system, and the need to trick the user into saving the document and sending it back.
CVE-2017-9806: Out-of-Bounds Write in Writer's WW8Fonts Constructor
A vulnerability in the OpenOffice Writer DOC file parser, and specifically in the WW8Fonts Constructor, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.
CVE-2017-12607: Out-of-Bounds Write in Impress' PPT Filter
A vulnerability in OpenOffice's PPT file parser, and specifically in PPTStyleSheet, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.
CVE-2017-12608: Out-of-Bounds Write in Writer's ImportOldFormatStyles
A vulnerability in OpenOffice Writer DOC file parser, and specifically in ImportOldFormatStyles, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.
The cURL project reports:
libcurl contains a buffer overrun flaw in the IMAP handler.
An IMAP FETCH response line indicates the size of the returned data, in number of bytes. When that response says the data is zero bytes, libcurl would pass on that (non-existing) data with a pointer and the size (zero) to the deliver-data function.
libcurl's deliver-data function treats zero as a magic number and invokes strlen() on the data to figure out the length. The strlen() is called on a heap based buffer that might not be zero terminated so libcurl might read beyond the end of it into whatever memory lies after (or just crash) and then deliver that to the application as if it was actually downloaded.
Frederik Deweerdt reports:
Multiple Denial-of-Service vulnerabilities exist in h2o workers - see references for full details.
CVE-2017-10868: Worker processes may crash when receiving a request with invalid framing.
CVE-2017-10869: The stack may overflow when proxying huge requests.
Irssi reports:
When installing themes with unterminated colour formatting sequences, Irssi may access data beyond the end of the string.
While waiting for the channel synchronisation, Irssi may incorrectly fail to remove destroyed channels from the query list, resulting in use after free conditions when updating the state later on.
Certain incorrectly formatted DCC CTCP messages could cause NULL pointer dereference.
Overlong nicks or targets may result in a NULL pointer dereference while splitting the message.
In certain cases Irssi may fail to verify that a Safe channel ID is long enough, causing reads beyond the end of the string.

cacti developers report:
The file include/global_session.php in Cacti 1.1.25 has XSS related to (1) the URI or (2) the refresh page.
Several vulnerabilities: symlink directory traversal, absolute path directory traversal and buffer overflow were discovered in the arj archiver.
MIT reports:
CVE-2017-11368:
In MIT krb5 1.7 and later, an authenticated attacker can cause an assertion failure in krb5kdc by sending an invalid S4U2Self or S4U2Proxy request.
CVE-2017-11462:
RFC 2744 permits a GSS-API implementation to delete an existing security context on a second or subsequent call to gss_init_sec_context() or gss_accept_sec_context() if the call results in an error. This API behavior has been found to be dangerous, leading to the possibility of memory errors in some callers. For safety, GSS-API implementations should instead preserve existing security contexts on error until the caller deletes them.
All versions of MIT krb5 prior to this change may delete acceptor contexts on error. Versions 1.13.4 through 1.13.7, 1.14.1 through 1.14.5, and 1.15 through 1.15.1 may also delete initiator contexts on error.

Solr developers report:
Lucene XML parser does not explicitly prohibit doctype declaration and expansion of external entities which leads to arbitrary HTTP requests to the local SOLR instance and to bypass all firewall restrictions.
Solr "RunExecutableListener" class can be used to execute arbitrary commands on specific events, for example after each update query. The problem is that such listener can be enabled with any parameters just by using Config API with add-listener command.
jenkins developers report:
A total of 11 issues are reported, please see reference URL for details.
The Xen project reports multiple vulnerabilities.
Mozilla reports:
During TLS 1.2 exchanges, handshake hashes are generated which point to a message buffer. This saved data is used for later messages but in some cases, the handshake transcript can exceed the space available in the current buffer, causing the allocation of a new buffer. This leaves a pointer pointing to the old, freed buffer, resulting in a use-after-free when handshake hashes are then calculated afterwards. This can result in a potentially exploitable crash.
osip developers reports:
In libosip2 in GNU oSIP 4.1.0 and 5.0.0, a malformed SIP message can lead to a heap buffer overflow in the msg_osip_body_parse() function defined in osipparser2/osip_message_parse.c, resulting in a remote DoS.

Alan Coopersmith reports:
X.Org thanks Michal Srb of SuSE for finding these issues and bringing them to our attention, Julien Cristau of Debian for getting the fixes integrated, and Adam Jackson of Red Hat for publishing the release.
tomcat developers reports:
When running Apache Tomcat versions 9.0.0.M1 to 9.0.0, 8.5.0 to 8.5.22, 8.0.0.RC1 to 8.0.46 and 7.0.0 to 7.0.81 with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.
The cURL project reports:
FTP PWD response parser out of bounds read
libcurl may read outside of a heap allocated buffer when doing FTP.
When libcurl connects to an FTP server and successfully logs in (anonymous or not), it asks the server for the current directory with the PWD command. The server then responds with a 257 response containing the path, inside double quotes. The returned path name is then kept by libcurl for subsequent uses.
Due to a flaw in the string parser for this directory name, a directory name passed like this but without a closing double quote would lead to libcurl not adding a trailing NUL byte to the buffer holding the name. When libcurl would then later access the string, it could read beyond the allocated heap buffer and crash or wrongly access data beyond the buffer, thinking it was part of the path.
A malicious server could abuse this fact and effectively prevent libcurl-based clients to work with it - the PWD command is always issued on new FTP connections and the mistake has a high chance of causing a segfault.
There is no limit on the password length.
A remote attacker may be able to cause an affected SSH server to use excessive amount of CPU by sending very long passwords, when PasswordAuthentication is enabled by the system administrator.
There is a programming error in the Heimdal implementation that used an unauthenticated, plain-text version of the KDC-REP service name found in a ticket.
An attacker who has control of the network between a client and the service it talks to will be able to impersonate the service, allowing a successful man-in-the-middle (MITM) attack that circumvents the mutual authentication.

sam2p developers report:
In sam2p 0.49.3, a heap-based buffer overflow exists in the pcxLoadImage24 function of the file in_pcx.cpp.
In sam2p 0.49.3, the in_xpm_reader function in in_xpm.cpp has an integer signedness error, leading to a crash when writing to an out-of-bounds array element.
In sam2p 0.49.3, an integer overflow exists in the pcxLoadImage24 function of the file in_pcx.cpp, leading to an invalid write operation.
In sam2p 0.49.3, the pcxLoadRaster function in in_pcx.cpp has an integer signedness error leading to a heap-based buffer overflow.
Because of an integer overflow in sam2p 0.49.3, a loop executes 0xffffffff times, ending with an invalid read of size 1 in the Image::Indexed::sortPal function in image.cpp. However, this also causes memory corruption because of an attempted write to the invalid d[0xfffffffe] array element.
In sam2p 0.49.3, there is an invalid read of size 2 in the parse_rgb function in in_xpm.cpp. However, this can also cause a write to an illegal address.
libraw developers report:
In LibRaw through 0.18.4, an out of bounds read flaw related to kodak_65000_load_raw has been reported in dcraw/dcraw.c and internal/dcraw_common.cpp. An attacker could possibly exploit this flaw to disclose potentially sensitive memory or cause an application crash.
Steffan Karger reports:
The bounds check in read_key() was performed after using the value, instead of before. If 'key-method 1' is used, this allowed an attacker to send a malformed packet to trigger a stack buffer overflow. [...]
Note that 'key-method 1' has been replaced by 'key method 2' as the default in OpenVPN 2.0 (released on 2005-04-17), and explicitly deprecated in 2.4 and marked for removal in 2.5. This should limit the amount of users impacted by this issue.
MITRE reports:

The Asterisk project reports:
This is a follow up advisory to AST-2017-005.
Insufficient RTCP packet validation could allow reading stale buffer contents and when combined with the "nat" and "symmetric_rtp" options allow redirecting where Asterisk sends the next RTCP report.
The RTP stream qualification to learn the source address of media always accepted the first RTP packet as the new source and allowed what AST-2017-005 was mitigating. The intent was to qualify a series of packets before accepting the new source address.
The RTP/RTCP stack will now validate RTCP packets before processing them.
Ruby blog:
CVE-2017-0898: Buffer underrun vulnerability in Kernel.sprintf
If a malicious format string which contains a precious specifier (*) is passed and a huge minus value is also passed to the specifier, buffer underrun may be caused. In such situation, the result may contains heap, or the Ruby interpreter may crash.
CVE-2017-10784: Escape sequence injection vulnerability in the Basic authentication of WEBrick
When using the Basic authentication of WEBrick, clients can pass an arbitrary string as the user name. WEBrick outputs the passed user name intact to its log, then an attacker can inject malicious escape sequences to the log and dangerous control characters may be executed on a victim’s terminal emulator.
This vulnerability is similar to a vulnerability already fixed, but it had not been fixed in the Basic authentication.
CVE-2017-14033: Buffer underrun vulnerability in OpenSSL ASN1 decode
If a malicious string is passed to the decode method of OpenSSL::ASN1, buffer underrun may be caused and the Ruby interpreter may crash.
CVE-2017-14064: Heap exposure vulnerability in generating JSON
The generate method of JSON module optionally accepts an instance of JSON::Ext::Generator::State class. If a malicious instance is passed, the result may include contents of heap.
Gem in a box XSS vulenrability - CVE-2017-14506:
Malicious attacker create GEM file with crafted homepage value (gem.homepage in .gemspec file) includes XSS payload.
The attacker access geminabox system and uploads the gem file (or uses CSRF/SSRF attack to do so).
From now on, any user access Geminabox web server, executes the malicious XSS payload, that will delete any gems on the server, and won't let users use the geminabox anymore. (make victim's browser crash or redirect them to other hosts).
The Fuzzing Project reports:
Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.

The Asterisk project reports:
A carefully crafted URI in a From, To or Contact header could cause Asterisk to crash.
The Asterisk project reports:
AST-2017-005 - A change was made to the strict RTP support in the RTP stack to better tolerate late media when a reinvite occurs. When combined with the symmetric RTP support this introduced an avenue where media could be hijacked. Instead of only learning a new address when expected the new code allowed a new source address to be learned at all times.
AST-2017-006 - The app_minivm module has an "externnotify" program configuration option that is executed by the MinivmNotify dialplan application. The application uses the caller-id name and number as part of a built string passed to the OS shell for interpretation and execution. Since the caller-id name and number can come from an untrusted source, a crafted caller-id name or number allows an arbitrary shell command injection.

Poppler developers report:
Poppler is prone to a stack-based buffer-overflow vulnerability.
Successful exploits may allow attackers to crash the affected application, resulting in denial-of-service condition. Due to the nature of this issue, arbitrary code execution may be possible but this has not been confirmed.
PHPMailer reports:
Fix XSS vulnerability in one of the code examples, CVE-2017-11503. The code_generator.phps example did not filter user input prior to output. This file is distributed with a .phps extension, so it it not normally executable unless it is explicitly renamed, so it is safe by default. There was also an undisclosed potential XSS vulnerability in the default exception handler (unused by default). Patches for both issues kindly provided by Patrick Monnerat of the Fedora Project.
SaltStack reports:
Correct a flaw in minion id validation which could allow certain minions to authenticate to a master despite not having the correct credentials. To exploit the vulnerability, an attacker must create a salt-minion with an ID containing characters that will cause a directory traversal. Credit for discovering the security flaw goes to: Vernhk@qq.com

mnaberez reports:
supervisord can be configured to run an HTTP server on a TCP socket and/or a Unix domain socket. The HTTP server is how supervisorctl communicates with supervisord. If an HTTP server has been enabled, it will always serve both HTML pages and an XML-RPC interface. A vulnerability has been found where an authenticated client can send a malicious XML-RPC request to supervisord that will run arbitrary shell commands on the server. The commands will be run as the same user as supervisord. Depending on how supervisord has been configured, this may be root.
This vulnerability can only be exploited by an authenticated client or if supervisord has been configured to run an HTTP server without authentication. If authentication has not been enabled, supervisord will log a message at the critical level every time it starts.

Mercurial Release Notes:
CVE-2017-1000115
Mercurial's symlink auditing was incomplete prior to 4.3, and could be abused to write to files outside the repository.
CVE-2017-1000116
Mercurial was not sanitizing hostnames passed to ssh, allowing shell injection attacks on clients by specifying a hostname starting with -oProxyCommand. This is also present in Git (CVE-2017-1000117) and Subversion (CVE-2017-9800), so please patch those tools as well if you have them installed.
subversion team reports:
A Subversion client sometimes connects to URLs provided by the repository. This happens in two primary cases: during 'checkout', 'export', 'update', and 'switch', when the tree being downloaded contains svn:externals properties; and when using 'svnsync sync' with one URL argument.
A maliciously constructed svn+ssh:// URL would cause Subversion clients to run an arbitrary shell command. Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server.
The vulnerability affects all clients, including those that use file://, http://, and plain (untunneled) svn://.
An exploit has been tested.
GitLab reports:
Remote Command Execution in git client
An external code review performed by Recurity-Labs identified a remote command execution vulnerability in git that could be exploited via the "Repo by URL" import option in GitLab. The command line git client was not properly escaping command line arguments in URLs using the SSH protocol before invoking the SSH client. A specially crafted URL could be used to execute arbitrary shell commands on the GitLab server.
To fully patch this vulnerability two fixes were needed. The Omnibus versions of GitLab contain a patched git client. For source users who may still be running an older version of git, GitLab now also blocks import URLs containing invalid host and usernames.
This issue has been assigned CVE-2017-12426.Improper sanitization of GitLab export files on import
GitLab versions 8.13.3, 8.12.8, 8.11.10, 8.10.13, and 8.9.12 contained a patch for a critical directory traversal vulnerability in the GitLab export feature that could be exploited by including symlinks in the export file and then re-importing it to a GitLab instance. This vulnerability was patched by checking for and removing symlinks in these files on import.
Recurity-Labs also determined that this fix did not properly remove symlinks for hidden files. Though not as dangerous as the original vulnerability hidden file symlinks could still be used to steal copies of git repositories belonging to other users if the path to the git repository was known by the attacker. An updated fix has been included in these releases that properly removes all symlinks.
This import option was not made available to non-admin users until GitLab 8.13.0.

The samba project reports:
A MITM attacker may impersonate a trusted server and thus gain elevated access to the domain by returning malicious replication or authorization data.
Updates are now available for all active Node.js release lines as well as the 7.x line. These include the fix for the high severity vulnerability identified in the initial announcement, one additional lower priority Node.js vulnerability in the 4.x release line, as well as some lower priority fixes for Node.js dependencies across the current release lines.
Constant Hashtable Seeds (CVE pending)
Node.js was susceptible to hash flooding remote DoS attacks as the HashTable seed was constant across a given released version of Node.js. This was a result of building with V8 snapshots enabled by default which caused the initially randomized seed to be overwritten on startup. Thanks to Jann Horn of Google Project Zero for reporting this vulnerability.
This is a high severity vulnerability and applies to all active release lines (4.x, 6.x, 8.x) as well as the 7.x line.
http.get with numeric authorization options creates uninitialized buffers
Application code that allows the auth field of the options object used with http.get() to be set to a number can result in an uninitialized buffer being created/used as the authentication string.
This is a low severity defect and only applies to the 4.x release line.

the PHP project reports:
- A stack out-of-bounds read occurs in match_at() during regular expression searching. A logical error involving order of validation and access in match_at() could result in an out-of-bounds read from a stack buffer (CVE-2017-9224).
- A heap out-of-bounds write or read occurs in next_state_val() during regular expression compilation. Octal numbers larger than 0xff are not handled correctly in fetch_token() and fetch_token_in_cc(). A malformed regular expression containing an octal number in the form of '\700' would produce an invalid code point value larger than 0xff in next_state_val(), resulting in an out-of-bounds write memory corruption (CVE-2017-9226).
- A stack out-of-bounds read occurs in mbc_enc_len() during regular expression searching. Invalid handling of reg->dmin in forward_search_range() could result in an invalid pointer dereference, as an out-of-bounds read from a stack buffer (CVE-2017-9227).
- A heap out-of-bounds write occurs in bitset_set_range() during regular expression compilation due to an uninitialized variable from an incorrect state transition. An incorrect state transition in parse_char_class() could create an execution path that leaves a critical local variable uninitialized until it's used as an index, resulting in an out-of-bounds write memory corruption (CVE-2017-9228).
- A SIGSEGV occurs in left_adjust_char_head() during regular expression compilation. Invalid handling of reg->dmax in forward_search_range() could result in an invalid pointer dereference, normally as an immediate denial-of-service condition (CVE-2017-9228).

ipfilter(4), capable of stateful packet inspection, using the "keep state" or "keep frags" rule options, will not only maintain the state of connections, such as TCP streams or UDP communication, it also maintains the state of fragmented packets. When a packet fragments are received they are cached in a hash table (and linked list). When a fragment is received it is compared with fragments already cached in the hash table for a match. If it does not match the new entry is used to create a new entry in the hash table. If on the other hand it does match, unfortunately the wrong entry is freed, the entry in the hash table. This results in use after free panic (and for a brief moment prior to the panic a memory leak due to the wrong entry being freed).
Carefully feeding fragments that are allowed to pass by an ipfilter(4) firewall can be used to cause a panic followed by reboot loop denial of service attack.

The Asterisk project reports:
A remote memory exhaustion can be triggered by sending an SCCP packet to Asterisk system with "chan_skinny" enabled that is larger than the length of the SCCP header but smaller than the packet length specified in the header. The loop that reads the rest of the packet doesn't detect that the call to read() returned end-of-file before the expected number of bytes and continues infinitely. The "partial data" message logging in that tight loop causes Asterisk to exhaust all available memory.
The Asterisk project reports:
A remote crash can be triggered by sending a SIP packet to Asterisk with a specially crafted CSeq header and a Via header with no branch parameter. The issue is that the PJSIP RFC 2543 transaction key generation algorithm does not allocate a large enough buffer. By overrunning the buffer, the memory allocation table becomes corrupted, leading to an eventual crash.
The multi-part body parser in PJSIP contains a logical error that can make certain multi-part body parts attempt to read memory from outside the allowed boundaries. A specially-crafted packet can trigger these invalid reads and potentially induce a crash.
This issues is in PJSIP, and so the issue can be fixed without performing an upgrade of Asterisk at all. However, we are releasing a new version of Asterisk with the bundled PJProject updated to include the fix.
If you are running Asterisk with chan_sip, this issue does not affect you.

Samuli Seppänen reports:
OpenVPN v2.4.0 was audited for security vulnerabilities independently by Quarkslabs (funded by OSTIF) and Cryptography Engineering (funded by Private Internet Access) between December 2016 and April 2017. The primary findings were two remote denial-of-service vulnerabilities. Fixes to them have been backported to v2.3.15.
An authenticated client can do the 'three way handshake' (P_HARD_RESET, P_HARD_RESET, P_CONTROL), where the P_CONTROL packet is the first that is allowed to carry payload. If that payload is too big, the OpenVPN server process will stop running due to an ASSERT() exception. That is also the reason why servers using tls-auth/tls-crypt are protected against this attack - the P_CONTROL packet is only accepted if it contains the session ID we specified, with a valid HMAC (challenge-response). (CVE-2017-7478)
An authenticated client can cause the server's the packet-id counter to roll over, which would lead the server process to hit an ASSERT() and stop running. To make the server hit the ASSERT(), the client must first cause the server to send it 2^32 packets (at least 196 GB).

cURL security advisory:
libcurl would attempt to resume a TLS session even if the client certificate had changed. That is unacceptable since a server by specification is allowed to skip the client certificate check on resume, and may instead use the old identity which was established by the previous certificate (or no certificate).
libcurl supports by default the use of TLS session id/ticket to resume previous TLS sessions to speed up subsequent TLS handshakes. They are used when for any reason an existing TLS connection couldn't be kept alive to make the next handshake faster.
This flaw is a regression and identical to CVE-2016-5419 reported on August 3rd 2016, but affecting a different version range.

ISC reports:
A query with a specific set of characteristics could cause a server using DNS64 to encounter an assertion failure and terminate.
An attacker could deliberately construct a query, enabling denial-of-service against a server if it was configured to use the DNS64 feature and other preconditions were met.
Mistaken assumptions about the ordering of records in the answer section of a response containing CNAME or DNAME resource records could lead to a situation in which named would exit with an assertion failure when processing a response in which records occurred in an unusual order.
named contains a feature which allows operators to issue commands to a running server by communicating with the server process over a control channel, using a utility program such as rndc.
A regression introduced in a recent feature change has created a situation under which some versions of named can be caused to exit with a REQUIRE assertion failure if they are sent a null command string.

The cURL project reports:
There were two bugs in curl's parser for the command line option --write-out (or -w for short) that would skip the end of string zero byte if the string ended in a % (percent) or \ (backslash), and it would read beyond that buffer in the heap memory and it could then potentially output pieces of that memory to the terminal or the target file etc..

The Xen Project reports:
Unprivileged guests may be able to stall progress of the control domain or driver domain, possibly leading to a Denial of Service (DoS) of the entire host.
The phpMyAdmin team reports:
Summary
Bypass $cfg['Servers'][$i]['AllowNoPassword']
Description
A vulnerability was discovered where the restrictions caused by $cfg['Servers'][$i]['AllowNoPassword'] = false are bypassed under certain PHP versions. This can allow the login of users who have no password set even if the administrator has set $cfg['Servers'][$i]['AllowNoPassword'] to false (which is also the default).
This behavior depends on the PHP version used (it seems PHP 5 is affected, while PHP 7.0 is not).
Severity
We consider this vulnerability to be of moderate severity.
Mitigation factor
Set a password for all users.
Samba team reports:
A time-of-check, time-of-use race condition can allow clients to access non-exported parts of the file system via symlinks.

CVE-2017-6377: Editor module incorrectly checks access to inline private files
CVE-2017-6379: Some admin paths were not protected with a CSRF token
CVE-2017-6381: Remote code execution
Simon G. Tatham reports:
Many versions of PuTTY prior to 0.68 have a heap-corrupting integer overflow bug in the ssh_agent_channel_data function which processes messages sent by remote SSH clients to a forwarded agent connection. [...]
This bug is only exploitable at all if you have enabled SSH agent forwarding, which is turned off by default. Moreover, an attacker able to exploit this bug would have to have already be able to connect to the Unix-domain socket representing the forwarded agent connection. Since any attacker with that capability would necessarily already be able to generate signatures with your agent's stored private keys, you should in normal circumstances be defended against this vulnerability by the same precautions you and your operating system were already taking to prevent untrusted people from accessing your SSH agent.

Janos Follath reports:
- If a malicious peer supplies a certificate with a specially crafted secp224k1 public key, then an attacker can cause the server or client to attempt to free block of memory held on stack. Depending on the platform, this could result in a Denial of Service (client crash) or potentially could be exploited to allow remote code execution with the same privileges as the host application.
- If the client and the server both support MD5 and the client can be tricked to authenticate to a malicious server, then the malicious server can impersonate the client. To launch this man in the middle attack, the adversary has to compute a chosen-prefix MD5 collision in real time. This is very expensive computationally, but can be practical. Depending on the platform, this could result in a Denial of Service (client crash) or potentially could be exploited to allow remote code execution with the same privileges as the host application.
- A bug in the logic of the parsing of a PEM encoded Certificate Revocation List in mbedtls_x509_crl_parse() can result in an infinite loop. In versions before 1.3.10 the same bug results in an infinite recursion stack overflow that usually crashes the application. Methods and means of acquiring the CRLs is not part of the TLS handshake and in the strict TLS setting this vulnerability cannot be triggered remotely. The vulnerability cannot be triggered unless the application explicitly calls mbedtls_x509_crl_parse() or mbedtls_x509_crl_parse_file()on a PEM formatted CRL of untrusted origin. In which case the vulnerability can be exploited to launch a denial of service attack against the application.

Albert Aastals Cid reports:
A directory traversal issue was found in KTNEF which can be exploited by tricking a user into opening a malicious winmail.dat file. The issue allows to write files with the permission of the user opening the winmail.dat file during extraction.
Albert Astals Cid reports:
Using a malicious PAC file, and then using exfiltration methods in the PAC function FindProxyForURL() enables the attacker to expose full https URLs.
This is a security issue since https URLs may contain sensitive information in the URL authentication part (user:password@host), and in the path and the query (e.g. access tokens).
This attack can be carried out remotely (over the LAN) since proxy settings allow "Detect Proxy Configuration Automatically". This setting uses WPAD to retrieve the PAC file, and an attacker who has access to the victim's LAN can interfere with the WPAD protocols (DHCP/DNS+HTTP) and inject his/her own malicious PAC instead of the legitimate one.
WordPress versions 4.7.2 and earlier are affected by six security issues.
- Cross-site scripting (XSS) via media file metadata.

ikiwiki reports:
The ikiwiki maintainers discovered further flaws similar to CVE-2016-9646 in the passwordauth plugin's use of CGI::FormBuilder, with a more serious impact:
An attacker who can log in to a site with a password can log in as a different and potentially more privileged user.
An attacker who can create a new account can set arbitrary fields in the user database for that account
Mitre reports:
ikiwiki 3.20161219 does not properly check if a revision changes the access permissions for a page on sites with the git and recentchanges plugins and the CGI interface enabled, which allows remote attackers to revert certain changes by leveraging permissions to change the page before the revision was made.
When CGI::FormBuilder->field("foo") is called in list context (and in particular in the arguments to a subroutine that takes named arguments), it can return zero or more values for foo from the CGI request, rather than the expected single value. This breaks the usual Perl parsing convention for named arguments, similar to CVE-2014-1572 in Bugzilla (which was caused by a similar API design issue in CGI.pm).

The MPD project reports:
httpd: fix two buffer overflows in IcyMetaData length calculation
The cURL project reports:
SSL_VERIFYSTATUS ignored
curl and libcurl support "OCSP stapling", also known as the TLS Certificate Status Request extension (using the CURLOPT_SSL_VERIFYSTATUS option). When telling curl to use this feature, it uses that TLS extension to ask for a fresh proof of the server's certificate's validity. If the server doesn't support the extension, or fails to provide said proof, curl is expected to return an error.
Due to a coding mistake, the code that checks for a test success or failure, ends up always thinking there's valid proof, even when there is none or if the server doesn't support the TLS extension in question. Contrary to how it used to function and contrary to how this feature is documented to work.
This could lead to users not detecting when a server's certificate goes invalid or otherwise be mislead that the server is in a better shape than it is in reality.
The Xen Project reports:
In CIRRUS_BLTMODE_MEMSYSSRC mode the bitblit copy routine cirrus_bitblt_cputovideo fails to check whether the specified memory region is safe. A malicious guest administrator can cause an out of bounds memory write, very likely exploitable as a privilege escalation.

The Apache Groovy project reports:
When an application with Groovy on classpath uses standard Java serialization mechanisms, e.g. to communicate between servers or to store local data, it is possible for an attacker to bake a special serialized object that will execute code directly when deserialized.

ISC reports:
A malformed query response received by a recursive server in response to a query of RTYPE ANY could trigger an assertion failure while named is attempting to add the RRs in the query response to the cache.
Depending on the type of query and the EDNS options in the query they receive, DNSSEC-enabled authoritative servers are expected to include RRSIG and other RRsets in their responses to recursive servers. DNSSEC-validating servers will also make specific queries for DS and other RRsets. Whether DNSSEC-validating or not, an error in processing malformed query responses that contain DNSSEC-related RRsets that are inconsistent with other RRsets in the same query response can trigger an assertion failure. Although the combination of properties which triggers the assertion should not occur in normal traffic, it is potentially possible for the assertion to be triggered deliberately by an attacker sending a specially-constructed answer.
An unusually-formed answer containing a DS resource record could trigger an assertion failure. While the combination of properties which triggers the assertion should not occur in normal traffic, it is potentially possible for the assertion to be triggered deliberately by an attacker sending a specially-constructed answer having the required properties.
An error in handling certain queries can cause an assertion failure when a server is using the nxdomain-redirect feature to cover a zone for which it is also providing authoritative service. A vulnerable server could be intentionally stopped by an attacker if it was using a configuration that met the criteria for the vulnerability and if the attacker could cause it to accept a query that possessed the required attributes.
The ssh-agent(1) agent supports loading a PKCS#11 module from outside a trusted whitelist. An attacker can request loading of a PKCS#11 module across forwarded agent-socket. [CVE-2016-10009]
When privilege separation is disabled, forwarded Unix domain sockets would be created by sshd(8) with the privileges of 'root' instead of the authenticated user. [CVE-2016-10010]
A remote attacker who have control of a forwarded agent-socket on a remote system and have the ability to write files on the system running ssh-agent(1) agent can run arbitrary code under the same user credential. Because the attacker must already have some control on both systems, it is relatively hard to exploit this vulnerability in a practical attack. [CVE-2016-10009]
When privilege separation is disabled (on FreeBSD, privilege separation is enabled by default and has to be explicitly disabled), an authenticated attacker can potentially gain root privileges on systems running OpenSSH server. [CVE-2016-10010]
Cesar Pereida Garcia reports:
The signing function in crypto/ecdsa/ecdsa_ossl.c in certain OpenSSL versions and forks is vulnerable to timing attacks when signing with the standardized elliptic curve P-256 despite featuring constant-time curve operations and modular inversion. A software defect omits setting the BN_FLG_CONSTTIME flag for nonces, failing to take a secure code path in the BN_mod_inverse method and therefore resulting in a cache-timing attack vulnerability.
A malicious user with local access can recover ECDSA P-256 private keys.

Check Point reports:
... discovered 3 fresh and previously unknown vulnerabilities (CVE-2016-7479, CVE-2016-7480, CVE-2016-7478) in the PHP 7 unserialize mechanism.
The first two vulnerabilities allow attackers to take full control over servers, allowing them to do anything they want with the website, from spreading malware to defacing it or stealing customer data.
The last vulnerability generates a Denial of Service attack which basically hangs the website, exhausts its memory consumption, and shuts it down.
The PHP security team issued fixes for two of the vulnerabilities on the 13th of October and 1st of December.

Legal Hackers reports:
An independent research uncovered a critical vulnerability in PHPMailer that could potentially be used by (unauthenticated) remote attackers to achieve remote arbitrary code execution in the context of the web server user and remotely compromise the target web application.
To exploit the vulnerability an attacker could target common website components such as contact/feedback forms, registration forms, password email resets and others that send out emails with the help of a vulnerable version of the PHPMailer class.
The first patch of the vulnerability CVE-2016-10033 was incomplete. This advisory demonstrates the bypass of the patch. The bypass allows to carry out Remote Code Execution on all current versions (including 5.2.19).
Samba team reports:
[CVE-2016-2123] Authenticated users can supply malicious dnsRecord attributes on DNS objects and trigger a controlled memory corruption.
[CVE-2016-2125] Samba client code always requests a forwardable ticket when using Kerberos authentication. This means the target server, which must be in the current or trusted domain/realm, is given a valid general purpose Kerberos "Ticket Granting Ticket" (TGT), which can be used to fully impersonate the authenticated user or service.
[CVE-2016-2126] A remote, authenticated, attacker can cause the winbindd process to crash using a legitimate Kerberos ticket due to incorrect handling of the PAC checksum. A local service with access to the winbindd privileged pipe can cause winbindd to cache elevated access permissions.
Matthew Garett reports:
Reported this to upstream 8 months ago without response, so: libupnp's default behaviour allows anyone to write to your filesystem. Seriously. Find a device running a libupnp based server (Shodan says there's rather a lot), and POST a file to /testfile. Then GET /testfile ... and yeah if the server is running as root (it is) and is using / as the web root (probably not, but maybe) this gives full host fs access.

Project curl Security Advisory:
libcurl's (new) internal function that returns a good 32bit random value was implemented poorly and overwrote the pointer instead of writing the value into the buffer the pointer pointed to.
This random value is used to generate nonces for Digest and NTLM authentication, for generating boundary strings in HTTP formposts and more. Having a weak or virtually non-existent random there makes these operations vulnerable.
This function is brand new in 7.52.0 and is the result of an overhaul to make sure libcurl uses strong random as much as possible - provided by the backend TLS crypto libraries when present. The faulty function was introduced in this commit.
We are not aware of any exploit of this flaw.

A remote attacker who can send a specially crafted packet to cause a NULL pointer dereference that will crash ntpd, resulting in a Denial of Service. [CVE-2016-9311]
An exploitable configuration modification vulnerability exists in the control mode (mode 6) functionality of ntpd. If, against long-standing BCP recommendations, "restrict default noquery ..." is not specified, a specially crafted control mode packet can set ntpd traps, providing information disclosure and DDoS amplification, and unset ntpd traps, disabling legitimate monitoring by an attacker from remote. [CVE-2016-9310]
An attacker with access to the NTP broadcast domain can periodically inject specially crafted broadcast mode NTP packets into the broadcast domain which, while being logged by ntpd, can cause ntpd to reject broadcast mode packets from legitimate NTP broadcast servers. [CVE-2016-7427]
An attacker with access to the NTP broadcast domain can send specially crafted broadcast mode NTP packets to the broadcast domain which, while being logged by ntpd, will cause ntpd to reject broadcast mode packets from legitimate NTP broadcast servers. [CVE-2016-7428]
Origin timestamp problems were fixed in ntp 4.2.8p6. However, subsequent timestamp validation checks introduced a regression in the handling of some Zero origin timestamp checks. [CVE-2016-7431]
If ntpd is configured to allow mrulist query requests from a server that sends a crafted malicious packet, ntpd will crash on receipt of that crafted malicious mrulist query packet. [CVE-2016-7434]
An attacker who knows the sources (e.g., from an IPv4 refid in server response) and knows the system is (mis)configured in this way can periodically send packets with spoofed source address to keep the rate limiting activated and prevent ntpd from accepting valid responses from its sources. [CVE-2016-7426]
Ntp Bug 2085 described a condition where the root delay was included twice, causing the jitter value to be higher than expected. Due to a misinterpretation of a small-print variable in The Book, the fix for this problem was incorrect, resulting in a root distance that did not include the peer dispersion. The calculations and formulas have been reviewed and reconciled, and the code has been updated accordingly. [CVE-2016-7433]

The Xen Project reports:
Certain PV guest kernel operations (page table writes in particular) need emulation, and use Xen's general x86 instruction emulator. This allows a malicious guest kernel which asynchronously modifies its instruction stream to effect the clearing of EFLAGS.IF from the state used to return to guest context.
A malicious guest kernel administrator can cause a host hang or crash, resulting in a Denial of Service.
Apache Software Foundation reports:
Please reference CVE/URL list for details
The Xen Project reports:
The typical behaviour of singlestepping exceptions is determined at the start of the instruction, with a #DB trap being raised at the end of the instruction. SYSCALL (and SYSRET, although we don't implement it) behave differently because the typical behaviour allows userspace to escalate its privilege. (This difference in behaviour seems to be undocumented.) Xen wrongly raised the exception based on the flags at the start of the instruction.
Guest userspace which can invoke the instruction emulator can use this flaw to escalate its privilege to that of the guest kernel.

WordPress versions 4.6 and earlier are affected by two security issues: a cross-site scripting vulnerability via image filename, reported by SumOfPwn researcher Cengiz Han Sahin; and a path traversal vulnerability in the upgrade package uploader, reported by Dominik Schilling from the WordPress security team.
The Xen Project reports:
The x86 instruction CMPXCHG8B is supposed to ignore legacy operand size overrides; it only honors the REX.W override (making it CMPXCHG16B). So, the operand size is always 8 or 16. When support for CMPXCHG16B emulation was added to the instruction emulator, this restriction on the set of possible operand sizes was relied on in some parts of the emulation; but a wrong, fully general, operand size value was used for other parts of the emulation. As a result, if a guest uses a supposedly-ignored operand size prefix, a small amount of hypervisor stack data is leaked to the guests: a 96 bit leak to guests running in 64-bit mode; or, a 32 bit leak to other guests.
A malicious unprivileged guest may be able to obtain sensitive information from the host.
The PHP project reports:
This is a security release. Several security bugs were fixed in this release.
The Asterisk project reports:
The chan_sip channel driver has a liberal definition for whitespace when attempting to strip the content between a SIP header name and a colon character. Rather than following RFC 3261 and stripping only spaces and horizontal tabs, Asterisk treats any non-printable ASCII character as if it were whitespace.
This mostly does not pose a problem until Asterisk is placed in tandem with an authenticating SIP proxy. In such a case, a crafty combination of valid and invalid To headers can cause a proxy to allow an INVITE request into Asterisk without authentication since it believes the request is an in-dialog request. However, because of the bug described above, the request will look like an out-of-dialog request to Asterisk. Asterisk will then process the request as a new call. The result is that Asterisk can process calls from unvetted sources without any authentication.
If you do not use a proxy for authentication, then this issue does not affect you.
If your proxy is dialog-aware (meaning that the proxy keeps track of what dialogs are currently valid), then this issue does not affect you.
If you use chan_pjsip instead of chan_sip, then this issue does not affect you.
The Asterisk project reports:
If an SDP offer or answer is received with the Opus codec and with the format parameters separated using a space the code responsible for parsing will recursively call itself until it crashes. This occurs as the code does not properly handle spaces separating the parameters. This does NOT require the endpoint to have Opus configured in Asterisk. This also does not require the endpoint to be authenticated. If guest is enabled for chan_sip or anonymous in chan_pjsip an SDP offer or answer is still processed and the crash occurs.
Multiple sources report:
CVE-2015-2141: The InvertibleRWFunction::CalculateInverse function in rw.cpp in libcrypt++ 5.6.2 does not properly blind private key operations for the Rabin-Williams digital signature algorithm, which allows remote attackers to obtain private keys via a timing attack. Fixed in 5.6.3.
CVE-2016-3995: Incorrect implementation of Rijndael timing attack countermeasure. Fixed in 5.6.4.
CVE-2016-7420: Library built without -DNDEBUG could egress sensitive information to the filesystem via a core dump if an assert was triggered. Fixed in 5.6.5.
The bounds checking of accesses to guest memory greater than 4GB by device emulations is subject to integer overflow.
For a bhyve virtual machine with more than 3GB of guest memory configured, a malicious guest could craft device descriptors that could give it access to the heap of the bhyve process. Since the bhyve process is running as root, this may allow guests to obtain full control of the hosts they're running on.
A specially crafted argument can trigger a static buffer overflow in the library, with possibility to rewrite following static buffers that belong to other library functions.
Due to very limited use of the function in the existing applications, and limited length of the overflow, exploitation of the vulnerability does not seem feasible. None of the utilities and daemons in the base system are known to be vulnerable. However, careful review of third party software that may use the function was not performed.
An unexpected sequence of memory allocation failures combined with insufficient error checking could result in the construction and execution of an argument sequence that was not intended.
An attacker who controls the sequence of memory allocation failures and success may cause login(1) to run without authentication and may be able to cause misbehavior of login(1) replacements.
No practical way of controlling these memory allocation failures is known at this time.
mod_http2 reports:
The Apache HTTPD web server (from 2.4.17-2.4.23) did not apply limitations on request headers correctly when experimental module for the HTTP/2 protocol is used to access a resource.
The net result is that a the server allocates too much memory instead of denying the request. This can lead to memory exhaustion of the server by a properly crafted request.

Daniel P. Berrange reports:
The VNC server websockets decoder will read and buffer data from websockets clients until it sees the end of the HTTP headers, as indicated by \r\n\r\n. In theory this allows a malicious to trick QEMU into consuming an arbitrary amount of RAM.
The Xen Project reports:
pygrub, the boot loader emulator, fails to quote (or sanity check) its results when reporting them to its caller.
A malicious guest administrator can obtain the contents of sensitive host files (an information leak). Additionally, a malicious guest administrator can cause files on the host to be removed, causing a denial of service. In some unusual host configurations, ability to remove certain files may be usable for privilege escalation.
The Xen Project reports:
The compiler can emit optimizations in qemu which can lead to double fetch vulnerabilities. Specifically data on the rings shared between qemu and the hypervisor (which the guest under control can obtain mappings of) can be fetched twice (during which time the guest can alter the contents) possibly leading to arbitrary code execution in qemu.
Malicious administrators can exploit this vulnerability to take over the qemu process, elevating its privilege to that of the qemu process.
In a system not using a device model stub domain (or other techniques for deprivileging qemu), malicious guest administrators can thus elevate their privilege to that of the host.
The Xen Project reports:
The x86 instructions BT, BTC, BTR, and BTS, when used with a destination memory operand and a source register rather than an immediate operand, access a memory location offset from that specified by the memory operand as specified by the high bits of the register source.
A malicious guest can modify arbitrary memory, allowing for arbitrary code execution (and therefore privilege escalation affecting the whole host), a crash of the host (leading to a DoS), or information leaks. The vulnerability is sometimes exploitable by unprivileged guest user processes.
The Xen Project reports:
Along with their main kernel binary, unprivileged guests may arrange to have their Xen environment load (kernel) symbol tables for their use. The ELF image metadata created for this purpose has a few unused bytes when the symbol table binary is in 32-bit ELF format. These unused bytes were not properly cleared during symbol table loading.
A malicious unprivileged guest may be able to obtain sensitive information from the host.
The information leak is small and not under the control of the guest, so effectively exploiting this vulnerability is probably difficult.
The Xen Project reports:
Both writes to the FS and GS register base MSRs as well as the WRFSBASE and WRGSBASE instructions require their input values to be canonical, or a #GP fault will be raised. When the use of those instructions by the hypervisor was enabled, the previous guard against #GP faults (having recovery code attached) was accidentally removed.
A malicious guest administrator can crash the host, leading to a DoS.
The Xen Project reports:
LDTR, just like TR, is purely a protected mode facility. Hence even when switching to a VM86 mode task, LDTR loading needs to follow protected mode semantics. This was violated by the code.
On SVM (AMD hardware): a malicious unprivileged guest process can escalate its privilege to that of the guest operating system.
On both SVM and VMX (Intel hardware): a malicious unprivileged guest process can crash the guest.
The Xen Project reports:
The Xen x86 emulator erroneously failed to consider the unusability of segments when performing memory accesses.
The intended behaviour is as follows: The user data segment (%ds, %es, %fs and %gs) selectors may be NULL in 32-bit to prevent access. In 64-bit, NULL has a special meaning for user segments, and there is no way of preventing access. However, in both 32-bit and 64-bit, a NULL LDT system segment is intended to prevent access.
On Intel hardware, loading a NULL selector zeros the base as well as most attributes, but sets the limit field to its largest possible value. On AMD hardware, loading a NULL selector zeros the attributes, leaving the stale base and limit intact.
Xen may erroneously permit the access using unexpected base/limit values.
Ability to exploit this vulnerability on Intel is easy, but on AMD depends in a complicated way on how the guest kernel manages LDTs.
An unprivileged guest user program may be able to elevate its privilege to that of the guest operating system.
The Xen Project reports:
Instructions touching FPU, MMX, or XMM registers are required to raise a Device Not Available Exception (#NM) when either CR0.EM or CR0.TS are set. (Their AVX or AVX-512 extensions would consider only CR0.TS.) While during normal operation this is ensured by the hardware, if a guest modifies instructions while the hypervisor is preparing to emulate them, the #NM delivery could be missed.
Guest code in one task may thus (unintentionally or maliciously) read or modify register state belonging to another task in the same VM.
A malicious unprivileged guest user may be able to obtain or corrupt sensitive information (including cryptographic material) in other programs in the same guest.
The Xen Project reports:
When the EVTCHNOP_init_control operation is called with a bad guest frame number, it takes an error path which frees a control structure without also clearing the corresponding pointer. Certain subsequent operations (EVTCHNOP_expand_array or another EVTCHNOP_init_control), upon finding the non-NULL pointer, continue operation assuming it points to allocated memory.
A malicious guest administrator can crash the host, leading to a DoS. Arbitrary code execution (and therefore privilege escalation), and information leaks, cannot be excluded.
The Xen Project reports:
x86 HVM guests running with shadow paging use a subset of the x86 emulator to handle the guest writing to its own pagetables. There are situations a guest can provoke which result in exceeding the space allocated for internal state.
A malicious HVM guest administrator can cause Xen to fail a bug check, causing a denial of service to the host.
The Xen Project reports:
When emulating HVM instructions, Xen uses a small i-cache for fetches from guest memory. The code that handles cache misses does not check if the address from which it fetched lies within the cache before blindly writing to it. As such it is possible for the guest to overwrite hypervisor memory.
It is currently believed that the only way to trigger this bug is to use the way that Xen currently incorrectly wraps CS:IP in 16 bit modes. The included patch prevents such wrapping.
A malicious HVM guest administrator can escalate their privilege to that of the host.
The Xen Project reports:
On real hardware, a 32-bit PAE guest must leave the USER and RW bit clear in L3 pagetable entries, but the pagetable walk behaves as if they were set. (The L3 entries are cached in processor registers, and don't actually form part of the pagewalk.)
When running a 32-bit PV guest on a 64-bit Xen, Xen must always OR in the USER and RW bits for L3 updates for the guest to observe architectural behaviour. This is unsafe in combination with recursive pagetables.
As there is no way to construct an L3 recursive pagetable in native 32-bit PAE mode, disallow this option in 32-bit PV guests.
A malicious 32-bit PV guest administrator can escalate their privilege to that of the host.

The Apache Software Foundation reports:
The mod_dontdothat module of subversion and subversion clients using http(s):// are vulnerable to a denial-of-service attack, caused by exponential XML entity expansion. The attack targets XML parsers causing targeted process to consume excessive amounts of resources. The attack is also known as the "billions of laughs attack."
Mitre reports:
The HTBoundary_put_block function in HTBound.c for W3C libwww (w3c-libwww) allows remote servers to cause a denial of service (segmentation fault) via a crafted multipart/byteranges MIME message that triggers an out-of-bounds read.
The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1, as used in the XML-Twig module for Perl, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with malformed UTF-8 sequences that trigger a buffer over-read, related to the doProlog function in lib/xmlparse.c, a different vulnerability than CVE-2009-2625 and CVE-2009-3720.
The updatePosition function in lib/xmltok_impl.c in libexpat in Expat 2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with crafted UTF-8 sequences that trigger a buffer over-read, a different vulnerability than CVE-2009-2625.
The Mozilla Foundation reports:
Redirection from an HTTP connection to a data: URL assigns the referring site's origin to the data: URL in some circumstances. This can result in same-origin violations against a domain if it loads resources from malicious sites. Cross-origin setting of cookies has been demonstrated without the ability to read them.
The Roundcube project reports
steps/mail/sendmail.inc in Roundcube before 1.1.7 and 1.2.x before 1.2.3, when no SMTP server is configured and the sendmail program is enabled, does not properly restrict the use of custom envelope-from addresses on the sendmail command line, which allows remote authenticated users to execute arbitrary code via a modified HTTP request that sends a crafted e-mail message.
The Drupal development team reports:
Inconsistent name for term access query (Less critical - Drupal 7 and Drupal 8)
Drupal provides a mechanism to alter database SELECT queries before they are executed. Contributed and custom modules may use this mechanism to restrict access to certain entities by implementing hook_query_alter() or hook_query_TAG_alter() in order to add additional conditions. Queries can be distinguished by means of query tags. As the documentation on EntityFieldQuery::addTag() suggests, access-tags on entity queries normally follow the form ENTITY_TYPE_access (e.g. node_access). However, the taxonomy module's access query tag predated this system and used term_access as the query tag instead of taxonomy_term_access.
As a result, before this security release modules wishing to restrict access to taxonomy terms may have implemented an unsupported tag, or needed to look for both tags (term_access and taxonomy_term_access) in order to be compatible with queries generated both by Drupal core as well as those generated by contributed modules like Entity Reference. Otherwise information on taxonomy terms might have been disclosed to unprivileged users.
Incorrect cache context on password reset page (Less critical - Drupal 8)
The user password reset form does not specify a proper cache context, which can lead to cache poisoning and unwanted content on the page.
Confirmation forms allow external URLs to be injected (Moderately critical - Drupal 7)
Under certain circumstances, malicious users could construct a URL to a confirmation form that would trick users into being redirected to a 3rd party website after interacting with the form, thereby exposing the users to potential social engineering attacks.
Denial of service via transliterate mechanism (Moderately critical - Drupal 8)
A specially crafted URL can cause a denial of service via the transliterate mechanism.

OpenSSL reports:
- ChaCha20/Poly1305 heap-buffer-overflow (CVE-2016-7054)
Severity: High
TLS connections using *-CHACHA20-POLY1305 ciphersuites are susceptible to a DoS attack by corrupting larger payloads. This can result in an OpenSSL crash. This issue is not considered to be exploitable beyond a DoS.- CMS Null dereference (CVE-2016-7053)
Severity: Medium
Applications parsing invalid CMS structures can crash with a NULL pointer dereference. This is caused by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0 which can result in a NULL value being passed to the structure callback if an attempt is made to free certain invalid encodings. Only CHOICE structures using a callback which do not handle NULL value are affected.- Montgomery multiplication may produce incorrect results (CVE-2016-7055)i
Severity: Low
There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure that handles input lengths divisible by, but longer than 256 bits.

[659475] High CVE-2016-5198: Out of bounds memory access in V8. Credit to Tencent Keen Security Lab, working with Trend Micro's Zero Day Initiative.
Due to improper handling of alert packets, OpenSSL would consume an excessive amount of CPU time processing undefined alert messages.
A remote attacker who can initiate handshakes with an OpenSSL based server can cause the server to consume a lot of computation power with very little bandwidth usage, and may be able to use this technique in a leveraged Denial of Service attack.

ISC reports:
A defect in BIND's handling of responses containing a DNAME answer can cause a resolver to exit after encountering an assertion failure in db.c or resolver.c
Cisco Talos reports:
Multiple integer overflow vulnerabilities exist within Memcached that could be exploited to achieve remote code execution on the targeted system. These vulnerabilities manifest in various Memcached functions that are used in inserting, appending, prepending, or modifying key-value data pairs. Systems which also have Memcached compiled with support for SASL authentication are also vulnerable to a third flaw due to how Memcached handles SASL authentication commands.
An attacker could exploit these vulnerabilities by sending a specifically crafted Memcached command to the targeted server. Additionally, these vulnerabilities could also be exploited to leak sensitive process information which an attacker could use to bypass common exploitation mitigations, such as ASLR, and can be triggered multiple times. This enables reliable exploitation which makes these vulnerabilities severe.

When processing the SSH_MSG_KEXINIT message, the server could allocate up to a few hundreds of megabytes of memory per each connection, before any authentication take place.
A remote attacker may be able to cause a SSH server to allocate an excessive amount of memory. Note that the default MaxStartups setting on FreeBSD will limit the effectiveness of this attack.

Apache Axis2 reports:
Apache Axis2 1.7.4 is a maintenance release that includes fixes for several issues, including the following security issues: Session fixation (AXIS2-4739) and XSS (AXIS2-5683) vulnerabilities affecting the admin console. A dependency on an Apache HttpClient version affected by known security vulnerabilities (CVE-2012-6153 and CVE-2014-3577); see AXIS2-5757.
Node.js has released new versions containing the following security fix:
The following releases all contain fixes for CVE-2016-5180 "ares_create_query single byte out of buffer write": Node.js v0.10.48 (Maintenance), Node.js v0.12.17 (Maintenance), Node.js v4.6.1 (LTS "Argon")
While this is not a critical update, all users of these release lines should upgrade at their earliest convenience.
Node.js v6.9.0 LTS contains the following security fixes, specific to v6.x:
Disable auto-loading of openssl.cnf: Don't automatically attempt to load an OpenSSL configuration file, from the OPENSSL_CONF environment variable or from the default location for the current platform. Always triggering a configuration file load attempt may allow an attacker to load compromised OpenSSL configuration into a Node.js process if they are able to place a file in a default location.
Patched V8 arbitrary memory read (CVE-2016-5172): The V8 parser mishandled scopes, potentially allowing an attacker to obtain sensitive information from arbitrary memory locations via crafted JavaScript code. This vulnerability would require an attacker to be able to execute arbitrary JavaScript code in a Node.js process.
Create a unique v8_inspector WebSocket address: Generate a UUID for each execution of the inspector. This provides additional security to prevent unauthorized clients from connecting to the Node.js process via the v8_inspector port when running with --inspect. Since the debugging protocol allows extensive access to the internals of a running process, and the execution of arbitrary code, it is important to limit connections to authorized tools only. Note that the v8_inspector protocol in Node.js is still considered an experimental feature. Vulnerability originally reported by Jann Horn.
All of these vulnerabilities are considered low-severity for Node.js users, however, users of Node.js v6.x should upgrade at their earliest convenience.

CVE-2016-9015: Certification verification failure
Adobe reports:
Adobe has released security updates for Adobe Flash Player for Windows, Macintosh, Linux and Chrome OS. These updates address a critical vulnerability that could potentially allow an attacker to take control of the affected system.
Adobe is aware of a report that an exploit for CVE-2016-7855 exists in the wild, and is being used in limited, targeted attacks against users running Windows versions 7, 8.1 and 10.
An unchecked array reference in the VGA device emulation code could potentially allow guests access to the heap of the bhyve process. Since the bhyve process is running as root, this may allow guests to obtain full control of the hosts they are running on.
For bhyve virtual machines with the "fbuf" framebuffer device configured, if exploited, a malicious guest could obtain full access to not just the host system, but to other virtual machines running on the system.

Apache Axis2 reports:
Apache Axis2 1.7.3 is a security release that contains a fix for CVE-2010-3981. That security vulnerability affects the admin console that is part of the Axis2 Web application and was originally reported for SAP BusinessObjects (which includes a version of Axis2). That report didn’t mention Axis2 at all and the Axis2 project only recently became aware (thanks to Devesh Bhatt and Nishant Agarwala) that the issue affects Apache Axis2 as well.
The Tor Blog reports:
Prevent a class of security bugs caused by treating the contents of a buffer chunk as if they were a NUL-terminated string. At least one such bug seems to be present in all currently used versions of Tor, and would allow an attacker to remotely crash most Tor instances, especially those compiled with extra compiler hardening. With this defense in place, such bugs can't crash Tor, though we should still fix them as they occur. Closes ticket 20384 (TROVE-2016-10-001).

Tencent's Xuanwu LAB reports:
A Heap Buffer Overflow (Out-of-Bounds Write) issue was found in function opj_dwt_interleave_v of dwt.c. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OpenJPEG.
An integer overflow issue exists in function opj_pi_create_decode of pi.c. It can lead to Out-Of-Bounds Read and Out-Of-Bounds Write in function opj_pi_next_cprl of pi.c (function opj_pi_next_lrcp, opj_pi_next_rlcp, opj_pi_next_rpcl, opj_pi_next_pcrl may also be vulnerable). This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OpenJPEG.
Redis team reports:
The redis-cli history file (in linenoise) is created with the default OS umask value which makes it world readable in most systems and could potentially expose authentication credentials to other users.
Flaws in libarchive's handling of symlinks and hard links allow overwriting files outside the extraction directory, or permission changes to a directory outside the extraction directory.
An attacker who can control freebsd-update's or portsnap's input to tar(1) can change file content or permissions on files outside of the update tool's working sandbox.
Flaws in portsnap's verification of downloaded tar files allows additional files to be included without causing the verification to fail. Portsnap may then use or execute these files.
An attacker who can conduct man in the middle attack on the network at the time when portsnap is run can cause portsnap to execute arbitrary commands under the credentials of the user who runs portsnap, typically root.
The implementation of bspatch is susceptible to integer overflows with carefully crafted input, potentially allowing an attacker who can control the patch file to write at arbitrary locations in the heap. This issue was partially addressed in FreeBSD-SA-16:25.bspatch, but some possible integer overflows remained.
An attacker who can control the patch file can cause a crash or run arbitrary code under the credentials of the user who runs bspatch, in many cases, root.
Moritz Bunkus reports:
most of the bugs fixed on 2016-09-06 and 2016-09-07 for issue #1780 are potentially exploitable. The scenario is arbitrary code execution with specially-crafted files.
Matthieu Herrb reports:
Tobias Stoeckmann from the OpenBSD project has discovered a number of issues in the way various X client libraries handle the responses they receive from servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues. These issue come in addition to the ones discovered by Ilja van Sprundel in 2013.
Most of these issues stem from the client libraries trusting the server to send correct protocol data, and not verifying that the values will not overflow or cause other damage. Most of the time X clients and servers are run by the same user, with the server more privileged than the clients, so this is not a problem, but there are scenarios in which a privileged client can be connected to an unprivileged server, for instance, connecting a setuid X client (such as a screen lock program) to a virtual X server (such as Xvfb or Xephyr) which the user has modified to return invalid data, potentially allowing the user to escalate their privileges.
ISC reports:
Testing by ISC has uncovered a critical error condition which can occur when a nameserver is constructing a response. A defect in the rendering of messages into packets can cause named to exit with an assertion failure in buffer.c while constructing a response to a query that meets certain criteria.

Matt Johnston reports:
If specific usernames including "%" symbols can be created on a system (validated by getpwnam()) then an attacker could run arbitrary code as root when connecting to Dropbear server. A dbclient user who can control username or host arguments could potentially run arbitrary code as the dbclient user. This could be a problem if scripts or webpages pass untrusted input to the dbclient program.
dropbearconvert import of OpenSSH keys could run arbitrary code as the local dropbearconvert user when parsing malicious key files.
dbclient could run arbitrary code as the local dbclient user if particular -m or -c arguments are provided. This could be an issue where dbclient is used in scripts.
dbclient or dropbear server could expose process memory to the running user if compiled with DEBUG_TRACE and running with -v
Frederik Deweerdt reported a denial-of-service attack vector due to an unhandled error condition during socket connection.
The cURL project reports
The four libcurl functions curl_escape(), curl_easy_escape(), curl_unescape and curl_easy_unescape perform string URL percent escaping and unescaping. They accept custom string length inputs in signed integer arguments.
The provided string length arguments were not properly checked and due to arithmetic in the functions, passing in the length 0xffffffff (2^32-1 or UINT_MAX or even just -1) would end up causing an allocation of zero bytes of heap memory that curl would attempt to write gigabytes of data into.

Dawid Golunski reports:
An independent research has revealed multiple severe MySQL vulnerabilities. This advisory focuses on a critical vulnerability with a CVEID of CVE-2016-6662 which can allow attackers to (remotely) inject malicious settings into MySQL configuration files (my.cnf) leading to critical consequences.
Florian Weimer of Redhat discovered that an optimization in RSA signature validation can result in disclosure of the server's private key under certain fault conditions.
Sebastian Ramacher identified an error in wolfSSL's implementation of the server side of the DTLS handshake, which could be abused for DDoS amplification or a DoS on the DTLS server itself.

The Asterisk project reports:
The overlap dialing feature in chan_sip allows chan_sip to report to a device that the number that has been dialed is incomplete and more digits are required. If this functionality is used with a device that has performed username/password authentication RTP resources are leaked. This occurs because the code fails to release the old RTP resources before allocating new ones in this scenario. If all resources are used then RTP port exhaustion will occur and no RTP sessions are able to be set up.
If overlap dialing support is not needed the "allowoverlap" option can be set to no. This will stop any usage of the scenario which causes the resource exhaustion.
The Asterisk project reports:
Asterisk can be crashed remotely by sending an ACK to it from an endpoint username that Asterisk does not recognize. Most SIP request types result in an "artificial" endpoint being looked up, but ACKs bypass this lookup. The resulting NULL pointer results in a crash when attempting to determine if ACLs should be applied.
This issue was introduced in the Asterisk 13.10 release and only affects that release.
This issue only affects users using the PJSIP stack with Asterisk. Those users that use chan_sip are unaffected.
Adam reports:
A serious vulnerability exists in when using m_sasl in combination with any services that support SASL EXTERNAL. To be vulnerable you must have m_sasl loaded, and have services which support SASL EXTERNAL authentication.
The late Tokio Kikuchi reported:
We may have to set lifetime for input forms because of recent activities on cross-site request forgery (CSRF). The form lifetime is successfully deployed in frameworks like web.py or plone etc. Proposed branch lp:~tkikuchi/mailman/form-lifetime implement lifetime in admin, admindb, options and edithtml interfaces. [...]
The web admin interface has been hardened against CSRF attacks by adding a hidden, encrypted token with a time stamp to form submissions and not accepting authentication by cookie if the token is missing, invalid or older than the new mm_cfg.py setting FORM_LIFETIME which defaults to one hour. Posthumous thanks go to Tokio Kikuchi for this implementation [...].
The OpenSSH project reports:
* sshd(8): Mitigate timing differences in password authentication that could be used to discern valid from invalid account names when long passwords were sent and particular password hashing algorithms are in use on the server. CVE-2016-6210, reported by EddieEzra.Harari at verint.com
* sshd(8): (portable only) Ignore PAM environment vars when UseLogin=yes. If PAM is configured to read user-specified environment variables and UseLogin=yes in sshd_config, then a hostile local user may attack /bin/login via LD_PRELOAD or similar environment variables set via PAM. CVE-2015-8325, found by Shayan Sadigh.
Mark Sapiro reports:
CSRF protection has been extended to the user options page. This was actually fixed by Tokio Kikuchi as part of the fix for LP: #775294 and intended for Mailman 2.1.15, but that fix wasn't completely merged at the time. The full fix also addresses the admindb, and edithtml pages as well as the user options page and the previously fixed admin pages. Thanks to Nishant Agarwala for reporting the issue.

Debian security team reports:
Tobias Stoeckmann discovered that cache files are insufficiently validated in fontconfig, a generic font configuration library. An attacker can trigger arbitrary free() calls, which in turn allows double free attacks and therefore arbitrary code execution. In combination with setuid binaries using crafted cache files, this could allow privilege escalation.
These packages have reached End of Life status and/or have been removed from the Ports Tree. They may contain undocumented security issues. Please take caution and find alternative software as soon as possible.

Hanz Jenson audit report:
I found 10 vulnerabilities. Some of these are critical and allow remote code execution. For the average user, that means that these vulnerabilities can be exploited by a malicious attacker in order to take over any Teamspeak server, not only becoming serveradmin, but getting a shell on the affected machine.
Puppet reports:
Puppet Enterprise previously included a puppet-agent MCollective plugin that allowed you to pass the `--server` argument to MCollective. This insecure argument enabled remote code execution via connection to an untrusted host. The puppet-agent MCollective version included in PE 2016.2.1, this option is disabled by default.
The implementation of bspatch does not check for a negative value on numbers of bytes read from the diff and extra streams, allowing an attacker who can control the patch file to write at arbitrary locations in the heap.
This issue was first discovered by The Chromium Project and reported independently by Lu Tung-Pin to the FreeBSD project.
An attacker who can control the patch file can cause a crash or run arbitrary code under the credentials of the user who runs bspatch, in many cases, root.
Multiple vulnerabilities have been discovered in the NTP suite:
The fix for Sec 3007 in ntp-4.2.8p7 contained a bug that could cause ntpd to crash. [CVE-2016-4957, Reported by Nicolas Edet of Cisco]
An attacker who knows the origin timestamp and can send a spoofed packet containing a CRYPTO-NAK to an ephemeral peer target before any other response is sent can demobilize that association. [CVE-2016-4953, Reported by Miroslav Lichvar of Red Hat]
An attacker who is able to spoof packets with correct origin timestamps from enough servers before the expected response packets arrive at the target machine can affect some peer variables and, for example, cause a false leap indication to be set. [CVE-2016-4954, Reported by Jakub Prokes of Red Hat]
An attacker who is able to spoof a packet with a correct origin timestamp before the expected response packet arrives at the target machine can send a CRYPTO_NAK or a bad MAC and cause the association's peer variables to be cleared. If this can be done often enough, it will prevent that association from working. [CVE-2016-4955, Reported by Miroslav Lichvar of Red Hat]
The fix for NtpBug2978 does not cover broadcast associations, so broadcast clients can be triggered to flip into interleave mode. [CVE-2016-4956, Reported by Miroslav Lichvar of Red Hat.]
Malicious remote attackers may be able to break time synchronization, or cause the ntpd(8) daemon to crash.
The implementation of historic stat(2) system call does not clear the output struct before copying it out to userland.
An unprivileged user can read a portion of uninitialised kernel stack data, which may contain sensitive information, such as the stack guard, portions of the file cache or terminal buffers, which an attacker might leverage to obtain elevated privileges.
The implementation of the TIOCGSERIAL ioctl(2) does not clear the output struct before copying it out to userland.
The implementation of the Linux sysinfo() system call does not clear the output struct before copying it out to userland.
An unprivileged user can read a portion of uninitialised kernel stack data, which may contain sensitive information, such as the stack guard, portions of the file cache or terminal buffers, which an attacker might leverage to obtain elevated privileges.
Incorrect argument handling in the socket code allows malicious local user to overwrite large portion of the kernel memory.
Malicious local user may crash kernel or execute arbitrary code in the kernel, potentially gaining superuser privileges.
Incorrect signedness comparison in the ioctl(2) handler allows a malicious local user to overwrite a portion of the kernel memory.
A local user may crash the kernel, read a portion of kernel memory and execute arbitrary code in kernel context. The result of executing an arbitrary kernel code is privilege escalation.
A special combination of sysarch(2) arguments, specify a request to uninstall a set of descriptors from the LDT. The start descriptor is cleared and the number of descriptors are provided. Due to lack of sufficient bounds checking during argument validity verification, unbound zero'ing of the process LDT and adjacent memory can be initiated from usermode.
This vulnerability could cause the kernel to panic. In addition it is possible to perform a local Denial of Service against the system by unprivileged processes.
A cross-protocol attack was discovered that could lead to decryption of TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle. Note that traffic between clients and non-vulnerable servers can be decrypted provided another server supporting SSLv2 and EXPORT ciphers (even with a different protocol such as SMTP, IMAP or POP3) shares the RSA keys of the non-vulnerable server. This vulnerability is known as DROWN. [CVE-2016-0800]
A double free bug was discovered when OpenSSL parses malformed DSA private keys and could lead to a DoS attack or memory corruption for applications that receive DSA private keys from untrusted sources. This scenario is considered rare. [CVE-2016-0705]
The SRP user database lookup method SRP_VBASE_get_by_user had confusing memory management semantics; the returned pointer was sometimes newly allocated, and sometimes owned by the callee. The calling code has no way of distinguishing these two cases. [CVE-2016-0798]
In the BN_hex2bn function, the number of hex digits is calculated using an int value |i|. Later |bn_expand| is called with a value of |i * 4|. For large values of |i| this can result in |bn_expand| not allocating any memory because |i * 4| is negative. This can leave the internal BIGNUM data field as NULL leading to a subsequent NULL pointer dereference. For very large values of |i|, the calculation |i * 4| could be a positive value smaller than |i|. In this case memory is allocated to the internal BIGNUM data field, but it is insufficiently sized leading to heap corruption. A similar issue exists in BN_dec2bn. This could have security consequences if BN_hex2bn/BN_dec2bn is ever called by user applications with very large untrusted hex/dec data. This is anticipated to be a rare occurrence. [CVE-2016-0797]
The internal |fmtstr| function used in processing a "%s" formatted string in the BIO_*printf functions could overflow while calculating the length of a string and cause an out-of-bounds read when printing very long strings. [CVE-2016-0799]
A side-channel attack was found which makes use of cache-bank conflicts on the Intel Sandy-Bridge microarchitecture which could lead to the recovery of RSA keys. [CVE-2016-0702]
s2_srvr.c did not enforce that clear-key-length is 0 for non-export ciphers. If clear-key bytes are present for these ciphers, they displace encrypted-key bytes. [CVE-2016-0703]
s2_srvr.c overwrites the wrong bytes in the master key when applying Bleichenbacher protection for export cipher suites. [CVE-2016-0704]
Servers that have SSLv2 protocol enabled are vulnerable to the "DROWN" attack which allows a remote attacker to fast attack many recorded TLS connections made to the server, even when the client did not make any SSLv2 connections themselves.
An attacker who can supply malformed DSA private keys to OpenSSL applications may be able to cause memory corruption which would lead to a Denial of Service condition. [CVE-2016-0705]
An attacker connecting with an invalid username can cause memory leak, which could eventually lead to a Denial of Service condition. [CVE-2016-0798]
An attacker who can inject malformed data into an application may be able to cause memory corruption which would lead to a Denial of Service condition. [CVE-2016-0797, CVE-2016-0799]
A local attacker who has control of code in a thread running on the same hyper-threaded core as the victim thread which is performing decryptions could recover RSA keys. [CVE-2016-0702]
An eavesdropper who can intercept SSLv2 handshake can conduct an efficient divide-and-conquer key recovery attack and use the server as an oracle to determine the SSLv2 master-key, using only 16 connections to the server and negligible computation. [CVE-2016-0703]
An attacker can use the Bleichenbacher oracle, which enables more efficient variant of the DROWN attack. [CVE-2016-0704]
A programming error in the Linux compatibility layer could cause the issetugid(2) system call to return incorrect information.
If an application relies on output of the issetugid(2) system call and that information is incorrect, this could lead to a privilege escalation.
The SNMP protocol supports an authentication model called USM, which relies on a shared secret. The default permission of the snmpd configuration file, /etc/snmpd.config, is weak and does not provide adequate protection against local unprivileged users.
A local user may be able to read the shared secret, if configured and used by the system administrator.
A programming error in processing a TCP connection with both TCP_MD5SIG and TCP_NOOPT socket options may lead to kernel crash.
A local attacker can crash the kernel, resulting in a denial-of-service.
A remote attack is theoretically possible, if server has a listening socket with TCP_NOOPT set, and server is either out of SYN cache entries, or SYN cache is disabled by configuration.
A programming error in the Linux compatibility layer setgroups(2) system call can lead to an unexpected results, such as overwriting random kernel memory contents.
It is possible for a local attacker to overwrite portions of kernel memory, which may result in a privilege escalation or cause a system panic.
A programming error in the handling of Linux futex robust lists may result in incorrect memory locations being accessed.
It is possible for a local attacker to read portions of kernel memory, which may result in a privilege escalation.
A lack of proper input checks in the ICMPv6 processing in the SCTP stack can lead to either a failed kernel assertion or to a NULL pointer dereference. In either case, a kernel panic will follow.
A remote, unauthenticated attacker can reliably trigger a kernel panic in a vulnerable system running IPv6. Any kernel compiled with both IPv6 and SCTP support is vulnerable. There is no requirement to have an SCTP socket open.
IPv4 ICMP processing is not impacted by this vulnerability.
In rpcbind(8), netbuf structures are copied directly, which would result in two netbuf structures that reference to one shared address buffer. When one of the two netbuf structures is freed, access to the other netbuf structure would result in an undefined result that may crash the rpcbind(8) daemon.
A remote attacker who can send specifically crafted packets to the rpcbind(8) daemon can cause it to crash, resulting in a denial of service condition.
If the kernel-mode IRET instruction generates an #SS or #NP exception, but the exception handler does not properly ensure that the right GS register base for kernel is reloaded, the userland GS segment may be used in the context of the kernel exception handler.
By causing an IRET with #SS or #NP exceptions, a local attacker can cause the kernel to use an arbitrary GS base, which may allow escalated privileges or panic the system.
Multiple integer overflows have been discovered in the XML_GetBuffer() function in the expat library.
The integer overflows may be exploited by using specifically crafted XML data and lead to infinite loop, or a heap buffer overflow, which results in a Denial of Service condition, or enables remote attackers to execute arbitrary code.
The input path in routed(8) will accept queries from any source and attempt to answer them. However, the output path assumes that the destination address for the response is on a directly connected network.
Upon receipt of a query from a source which is not on a directly connected network, routed(8) will trigger an assertion and terminate. The affected system's routing table will no longer be updated. If the affected system is a router, its routes will eventually expire from other routers' routing tables, and its networks will no longer be reachable unless they are also connected to another router.
Due to insufficient sanitization of the input patch stream, it is possible for a patch file to cause patch(1) to pass certain ed(1) scripts to the ed(1) editor, which would run commands.
This issue could be exploited to execute arbitrary commands as the user invoking patch(1) against a specially crafted patch file, which could be leveraged to obtain elevated privileges.
There is a mistake with the introduction of VNET, which converted the global limit on the number of segments that could belong to reassembly queues into a per-VNET limit. Because mbufs are allocated from a global pool, in the presence of a sufficient number of VNETs, the total number of mbufs attached to reassembly queues can grow to the total number of mbufs in the system, at which point all network traffic would cease.
An attacker who can establish concurrent TCP connections across a sufficient number of VNETs and manipulate the inbound packet streams such that the maximum number of mbufs are enqueued on each reassembly queue can cause mbuf cluster exhaustion on the target system, resulting in a Denial of Service condition.
As the default per-VNET limit on the number of segments that can belong to reassembly queues is 1/16 of the total number of mbuf clusters in the system, only systems that have 16 or more VNET instances are vulnerable.
Due to insufficient sanitization of the input patch stream, it is possible for a patch file to cause patch(1) to run commands in addition to the desired SCCS or RCS commands.
This issue could be exploited to execute arbitrary commands as the user invoking patch(1) against a specially crafted patch file, which could be leveraged to obtain elevated privileges.
TCP connections transitioning to the LAST_ACK state can become permanently stuck due to mishandling of protocol state in certain situations, which in turn can lead to accumulated consumption and eventual exhaustion of system resources, such as mbufs and sockets.
An attacker who can repeatedly establish TCP connections to a victim system (for instance, a Web server) could create many TCP connections that are stuck in LAST_ACK state and cause resource exhaustion, resulting in a denial of service condition. This may also happen in normal operation where no intentional attack is conducted, but an attacker who can send specifically crafted packets can trigger this more reliably.
The Neighbor Discover Protocol allows a local router to advertise a suggested Current Hop Limit value of a link, which will replace Current Hop Limit on an interface connected to the link on the FreeBSD system.
When the Current Hop Limit (similar to IPv4's TTL) is small, IPv6 packets may get dropped before they reached their destinations.
By sending specifically crafted Router Advertisement packets, an attacker on the local network can cause the FreeBSD system to lose the ability to communicate with another IPv6 node on a different network.
The default permission set by bsdinstall(8) installer when configuring full disk encrypted ZFS is too open.
A local attacker may be able to get a copy of the geli(8) provider's keyfile which is located at a fixed location.
An integer overflow in computing the size of IGMPv3 data buffer can result in a buffer which is too small for the requested operation.
An attacker who can send specifically crafted IGMP packets could cause a denial of service situation by causing the kernel to crash.
The input validation of received SCTP RE_CONFIG chunks is insufficient, and can result in a NULL pointer deference later.
A remote attacker who can send a malformed SCTP packet to a FreeBSD system that serves SCTP can cause a kernel panic, resulting in a Denial of Service.
Due to insufficient validation of the SCTP stream ID, which serves as an array index, a local unprivileged attacker can read or write 16-bits of kernel memory.
An unprivileged process can read or modify 16-bits of memory which belongs to the kernel. This may lead to exposure of sensitive information or allow privilege escalation.
A programming error in the standard I/O library's __sflush() function could erroneously adjust the buffered stream's internal state even when no write actually occurred in the case when write(2) system call returns an error.
The accounting mismatch would accumulate, if the caller does not check for stream status and will eventually lead to a heap buffer overflow.
Such overflows may lead to data corruption or the execution of arbitrary code at the privilege level of the calling program.
A malicious HTTP server could cause ftp(1) to execute arbitrary commands.
When operating on HTTP URIs, the ftp(1) client follows HTTP redirects, and uses the part of the path after the last '/' from the last resource it accesses as the output filename if '-o' is not specified.
If the output file name provided by the server begins with a pipe ('|'), the output is passed to popen(3), which might be used to execute arbitrary commands on the ftp(1) client machine.
When setlogin(2) is called while setting up a new login session, the login name is copied into an uninitialized stack buffer, which is then copied into a buffer of the same size in the session structure. The getlogin(2) system call returns the entire buffer rather than just the portion occupied by the login name associated with the session.
An unprivileged user can access this memory by calling getlogin(2) and reading beyond the terminating NUL character of the resulting string. Up to 16 (FreeBSD 8) or 32 (FreeBSD 9 and 10) bytes of kernel memory may be leaked in this manner for each invocation of setlogin(2).
This memory may contain sensitive information, such as portions of the file cache or terminal buffers, which an attacker might leverage to obtain elevated privileges.
Although OpenSSH is not multithreaded, when OpenSSH is compiled with Kerberos support, the Heimdal libraries bring in the POSIX thread library as a dependency. Due to incorrect library ordering while linking sshd(8), symbols in the C library which are shadowed by the POSIX thread library may not be resolved correctly at run time.
Note that this problem is specific to the FreeBSD build system and does not affect other operating systems or the version of OpenSSH available from the FreeBSD ports tree.
An incorrectly linked sshd(8) child process may deadlock while handling an incoming connection. The connection may then time out or be interrupted by the client, leaving the deadlocked sshd(8) child process behind. Eventually, the sshd(8) parent process stops accepting new connections.
An attacker may take advantage of this by repeatedly connecting and then dropping the connection after having begun, but not completed, the authentication process.
The namei facility will leak a small amount of kernel memory every time a sandboxed process looks up a nonexistent path name.
A remote attacker that can cause a sandboxed process (for instance, a web server) to look up a large number of nonexistent path names can cause memory exhaustion.
The input path in routed(8) will accept queries from any source and attempt to answer them. However, the output path assumes that the destination address for the response is on a directly connected network.
Upon receipt of a query from a source which is not on a directly connected network, routed(8) will trigger an assertion and terminate. The affected system's routing table will no longer be updated. If the affected system is a router, its routes will eventually expire from other routers' routing tables, and its networks will no longer be reachable unless they are also connected to another router.
Due to a missing length check in the code that handles DNS parameters, a malformed router advertisement message can result in a stack buffer overflow in rtsold(8).
Receipt of a router advertisement message with a malformed DNSSL option, for instance from a compromised host on the same network, can cause rtsold(8) to crash.
While it is theoretically possible to inject code into rtsold(8) through malformed router advertisement messages, it is normally compiled with stack protection enabled, rendering such an attack extremely difficult.
When rtsold(8) crashes, the existing DNS configuration will remain in force, and the kernel will continue to receive and process periodic router advertisements.
When a segment with the SYN flag for an already existing connection arrives, the TCP stack tears down the connection, bypassing a check that the sequence number in the segment is in the expected window.
An attacker who has the ability to spoof IP traffic can tear down a TCP connection by sending only 2 packets, if they know both TCP port numbers. In case one of the two port numbers is unknown, a successful attack requires less than 2**17 packets spoofed, which can be generated within less than a second on a decent connection to the Internet.
Buffer between control message header and data may not be completely initialized before being copied to userland. [CVE-2014-3952]
Three SCTP cmsgs, SCTP_SNDRCV, SCTP_EXTRCV and SCTP_RCVINFO, have implicit padding that may not be completely initialized before being copied to userland. In addition, three SCTP notifications, SCTP_PEER_ADDR_CHANGE, SCTP_REMOTE_ERROR and SCTP_AUTHENTICATION_EVENT, have padding in the returning data structure that may not be completely initialized before being copied to userland. [CVE-2014-3953]
An unprivileged local process may be able to retrieve portion of kernel memory.
For the generic control message, the process may be able to retrieve a maximum of 4 bytes of kernel memory.
For SCTP, the process may be able to retrieve 2 bytes of kernel memory for all three control messages, plus 92 bytes for SCTP_SNDRCV and 76 bytes for SCTP_EXTRCV. If the local process is permitted to receive SCTP notification, a maximum of 112 bytes of kernel memory may be returned to userland.
This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way. For example, a terminal buffer might include a user-entered password.
A specifically crafted Composite Document File (CDF) file can trigger an out-of-bounds read or an invalid pointer dereference. [CVE-2012-1571]
A flaw in regular expression in the awk script detector makes use of multiple wildcards with unlimited repetitions. [CVE-2013-7345]
A malicious input file could trigger infinite recursion in libmagic(3). [CVE-2014-1943]
A specifically crafted Portable Executable (PE) can trigger out-of-bounds read. [CVE-2014-2270]
An attacker who can cause file(1) or any other applications using the libmagic(3) library to be run on a maliciously constructed input can the application to crash or consume excessive CPU resources, resulting in a denial-of-service.
A NULL pointer dereference in the initialization code of the HZ module and an out of bounds array access in the initialization code of the VIQR module make iconv_open(3) calls involving HZ or VIQR result in an application crash.
Services where an attacker can control the arguments of an iconv_open(3) call can be caused to crash resulting in a denial-of-service. For example, an email encoded in HZ may cause an email delivery service to crash if it converts emails to a more generic encoding like UTF-8 before applying filtering rules.
The OpenPAM library searches for policy definitions in several locations. While doing so, the absence of a policy file is a soft failure (handled by searching in the next location) while the presence of an invalid file is a hard failure (handled by returning an error to the caller).
The policy parser returns the same error code (ENOENT) when a syntactically valid policy references a non-existent module as when the requested policy file does not exist. The search loop regards this as a soft failure and looks for the next similarly-named policy, without discarding the partially-loaded configuration.
A similar issue can arise if a policy contains an include directive that refers to a non-existent policy.
If a module is removed, or the name of a module is misspelled in the policy file, the PAM library will proceed with a partially loaded configuration. Depending on the exact circumstances, this may result in a fail-open scenario where users are allowed to log in without a password, or with an incorrect password.
In particular, if a policy references a module installed by a package or port, and that package or port is being reinstalled or upgraded, there is a brief window of time during which the module is absent and policies that use it may fail open. This can be especially damaging to Internet-facing SSH servers, which are regularly subjected to brute-force scans.
Due to an overlooked merge to -STABLE branches, the size for page fault kernel trace entries was set incorrectly.
A user who can enable kernel process tracing could end up reading the contents of kernel memory.
Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way; for example, a terminal buffer might include a user-entered password.
There is a programming error in sendmail(8) that prevented open file descriptors have close-on-exec properly set. Consequently a subprocess will be able to access all open files that the parent process have open.
A local user who can execute their own program for mail delivery will be able to interfere with an open SMTP connection.
FreeBSD may add a reassemble queue entry on the stack into the segment list when the reassembly queue reaches its limit. The memory from the stack is undefined after the function returns. Subsequent iterations of the reassembly function will attempt to access this entry.
An attacker who can send a series of specifically crafted packets with a connection could cause a denial of service situation by causing the kernel to crash.
Additionally, because the undefined on stack memory may be overwritten by other kernel threads, while extremely difficult, it may be possible for an attacker to construct a carefully crafted attack to obtain portion of kernel memory via a connected socket. This may result in the disclosure of sensitive information such as login credentials, etc. before or even without crashing the system.
The default devfs rulesets are not loaded on boot, even when jails are used. Device nodes will be created in the jail with their normal default access permissions, while most of them should be hidden and inaccessible.
Jailed processes can get access to restricted resources on the host system. For jailed processes running with superuser privileges this implies access to all devices on the system. This level of access could lead to information leakage and privilege escalation.
The kernel holds a lock over the source directory vnode while trying to convert the target directory file handle to a vnode, which needs to be returned with the lock held, too. This order may be in violation of normal lock order, which in conjunction with other threads that grab locks in the right order, constitutes a deadlock condition because no thread can proceed.
An attacker on a trusted client could cause the NFS server become deadlocked, resulting in a denial of service.
Problem Description:
The bsnmpd(8) daemon is prone to a stack-based buffer-overflow when it has received a specifically crafted GETBULK PDU request.
Impact:
This issue could be exploited to execute arbitrary code in the context of the service daemon, or crash the service daemon, causing a denial-of-service.

ISC reports:
DNS protocols were designed with the assumption that a certain amount of trust could be presumed between the operators of primary and secondary servers for a given zone. However, in current practice some organizations have scenarios which require them to accept zone data from sources that are not fully trusted (for example: providers of secondary name service). A party who is allowed to feed data into a zone (e.g. by AXFR, IXFR, or Dynamic DNS updates) can overwhelm the server which is accepting data by intentionally or accidentally exhausting that server's memory.
Problem Description:
When initializing the SCTP state cookie being sent in INIT-ACK chunks, a buffer allocated from the kernel stack is not completely initialized.
Impact:
Fragments of kernel memory may be included in SCTP packets and transmitted over the network. For each SCTP session, there are two separate instances in which a 4-byte fragment may be transmitted.
This memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way. For example, a terminal buffer might include a user-entered password.
Problem Description:
An integer overflow in computing the size of a temporary buffer can result in a buffer which is too small for the requested operation.
Impact:
An unprivileged process can read or write pages of memory which belong to the kernel. These may lead to exposure of sensitive information or allow privilege escalation.
Problem Description:
The kernel incorrectly uses client supplied credentials instead of the one configured in exports(5) when filling out the anonymous credential for a NFS export, when -network or -host restrictions are used at the same time.
Impact:
The remote client may supply privileged credentials (e.g. the root user) when accessing a file under the NFS share, which will bypass the normal access checks.

The Xen Project reports:
A guest can submit virtio requests without bothering to wait for completion and is therefore not bound by virtqueue size...
A malicious guest administrator can cause unbounded memory allocation in QEMU, which can cause an Out-of-Memory condition in the domain running qemu. Thus, a malicious guest administrator can cause a denial of service affecting the whole host.
The Xen Project reports:
Supervisor Mode Access Prevention is a hardware feature designed to make an Operating System more robust, by raising a pagefault rather than accidentally following a pointer into userspace. However, legitimate accesses into userspace require whitelisting, and the exception delivery mechanism for 32bit PV guests wasn't whitelisted.
A malicious 32-bit PV guest kernel can trigger a safety check, crashing the hypervisor and causing a denial of service to other VMs on the host.
The Xen Project reports:
The PV pagetable code has fast-paths for making updates to pre-existing pagetable entries, to skip expensive re-validation in safe cases (e.g. clearing only Access/Dirty bits). The bits considered safe were too broad, and not actually safe.
A malicious PV guest administrator can escalate their privilege to that of the host.

The Apache OpenOffice Project reports:
An OpenDocument Presentation .ODP or Presentation Template .OTP file can contain invalid presentation elements that lead to memory corruption when the document is loaded in Apache OpenOffice Impress. The defect may cause the document to appear as corrupted and OpenOffice may crash in a recovery-stuck mode requiring manual intervention. A crafted exploitation of the defect can allow an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.

TYPO3 reports:
Extbase request handling fails to implement a proper access check for requested controller/ action combinations, which makes it possible for an attacker to execute arbitrary Extbase actions by crafting a special request. To successfully exploit this vulnerability, an attacker must have access to at least one Extbase plugin or module action in a TYPO3 installation. The missing access check inevitably leads to information disclosure or remote code execution, depending on the action that an attacker is able to execute.

Mathias Svensson reports:
potential buffer write overrun in PixarLogDecode() on corrupted/unexpected images
Cisco Talos reports:
An out-of-bounds read vulnerability exists in the way 7-Zip handles Universal Disk Format (UDF) files.
Central to 7-Zip’s processing of UDF files is the CInArchive::ReadFileItem method. Because volumes can have more than one partition map, their objects are kept in an object vector. To start looking for an item, this method tries to reference the proper object using the partition map’s object vector and the "PartitionRef" field from the Long Allocation Descriptor. Lack of checking whether the "PartitionRef" field is bigger than the available amount of partition map objects causes a read out-of-bounds and can lead, in some circumstances, to arbitrary code execution.
Cisco Talos reports:
An exploitable heap overflow vulnerability exists in the NArchive::NHfs::CHandler::ExtractZlibFile method functionality of 7zip that can lead to arbitrary code execution.

ruby-saml users must update to 1.3.0, which implements 3 extra validations to mitigate this kind of attack.
Mitre reports:
The onReadyRead function in core/coreauthhandler.cpp in Quassel before 0.12.4 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via invalid handshake data.
Apache Software Foundation reports:
The Apache HTTPD web server (from 2.4.18-2.4.20) did not validate a X509 client certificate correctly when experimental module for the HTTP/2 protocol is used to access a resource.
The net result is that a resource that should require a valid client certificate in order to get access can be accessed without that credential.
The Xen Project reports:
When the libxl toolstack launches qemu for HVM guests, it pipes the output of stderr to a file in /var/log/xen. This output is not rate-limited in any way. The guest can easily cause qemu to print messages to stderr, causing this file to become arbitrarily large.
The disk containing the logfile can be exhausted, possibly causing a denial-of-service (DoS).
The Xen Project reports:
Qemu VGA module allows banked access to video memory using the window at 0xa00000 and it supports different access modes with different address calculations.
Qemu VGA module allows guest to edit certain registers in 'vbe' and 'vga' modes.
A privileged guest user could use CVE-2016-3710 to exceed the bank address window and write beyond the said memory area, potentially leading to arbitrary code execution with privileges of the Qemu process. If the system is not using stubdomains, this will be in domain 0.
A privileged guest user could use CVE-2016-3712 to cause potential integer overflow or OOB read access issues in Qemu, resulting in a DoS of the guest itself. More dangerous effect, such as data leakage or code execution, are not known but cannot be ruled out.
The Xen Project reports:
libxl's device-handling code freely uses and trusts information from the backend directories in xenstore.
A malicious driver domain can deny service to management tools.
The Xen Project reports:
The Page Size (PS) page table entry bit exists at all page table levels other than L1. Its meaning is reserved in L4, and conditionally reserved in L3 and L2 (depending on hardware capabilities). The software page table walker in the hypervisor, however, so far ignored that bit in L4 and (on respective hardware) L3 entries, resulting in pages to be treated as page tables which the guest OS may not have designated as such. If the page in question is writable by an unprivileged user, then that user will be able to map arbitrary guest memory.
On vulnerable OSes, guest user mode code may be able to establish mappings of arbitrary memory inside the guest, allowing it to elevate its privileges inside the guest.
The Xen Project reports:
Various parts of libxl device-handling code inappropriately use information from (partially) guest controlled areas of xenstore.
A malicious guest administrator can cause denial of service by resource exhaustion.
A malicious guest administrator can confuse and/or deny service to management facilities.
A malicious guest administrator of a guest configured with channel devices may be able to escalate their privilege to that of the backend domain (i.e., normally, to that of the host).
The Xen Project reports:
In the x86 shadow pagetable code, the guest frame number of a superpage mapping is stored in a 32-bit field. If a shadowed guest can cause a superpage mapping of a guest-physical address at or above 2^44 to be shadowed, the top bits of the address will be lost, causing an assertion failure or NULL dereference later on, in code that removes the shadow.
A HVM guest using shadow pagetables can cause the host to crash.
A PV guest using shadow pagetables (i.e. being migrated) with PV superpages enabled (which is not the default) can crash the host, or corrupt hypervisor memory, and so a privilege escalation cannot be ruled out.

Sushanth Sowmyan reports:
Some partition-level operations exist that do not explicitly also authorize privileges of the parent table. This can lead to issues when the parent table would have denied the operation, but no denial occurs because the partition-level privilege is not checked by the authorization framework, which defines authorization entities only from the table level upwards.
KoreLogic security reports:
Affected versions of SQLite reject potential tempdir locations if they are not readable, falling back to '.'. Thus, SQLite will favor e.g. using cwd for tempfiles on such a system, even if cwd is an unsafe location. Notably, SQLite also checks the permissions of '.', but ignores the results of that check.
Red Hat reports:
A vulnerability in smtplib allowing MITM attacker to perform a startTLS stripping attack. smtplib does not seem to raise an exception when the remote end (smtp server) is capable of negotiating starttls but fails to respond with 220 (ok) to an explicit call of SMTP.starttls(). This may allow a malicious MITM to perform a startTLS stripping attack if the client code does not explicitly check the response code for startTLS.

Mark Thomas reports:
CVE-2016-3092 is a denial of service vulnerability that has been corrected in the Apache Commons FileUpload component. It occurred when the length of the multipart boundary was just below the size of the buffer (4096 bytes) used to read the uploaded file. This caused the file upload process to take several orders of magnitude longer than if the boundary length was the typical tens of bytes.

Jack Lloyd reports:
Botan 1.10.13 has been released backporting some side channel protections for ECDSA signatures (CVE-2016-2849) and PKCS #1 RSA decryption (CVE-2015-7827).
MITRE reports:
The Miller-Rabin primality check in Botan before 1.10.8 and 1.11.x before 1.11.9 improperly uses a single random base, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a DH group.

Roundcube reports:
Fix XSS issue in href attribute on area tag (#5240).
The OpenSSL team reports:
Operations in the DSA signing algorithm should run in constant time in order to avoid side channel attacks. A flaw in the OpenSSL DSA implementation means that a non-constant time codepath is followed for certain operations. This has been demonstrated through a cache-timing attack to be sufficient for an attacker to recover the private DSA key.

ESnet reports:
A malicious process can connect to an iperf3 server and, by sending a malformed message on the control channel, corrupt the server process's heap area. This can lead to a crash (and a denial of service), or theoretically a remote code execution as the user running the iperf3 server. A malicious iperf3 server could potentially mount a similar attack on an iperf3 client.

Open vSwitch reports:
Multiple versions of Open vSwitch are vulnerable to remote buffer overflow attacks, in which crafted MPLS packets could overflow the buffer reserved for MPLS labels in an OVS internal data structure. The MPLS packets that trigger the vulnerability and the potential for exploitation vary depending on version:
Open vSwitch 2.1.x and earlier are not vulnerable.
In Open vSwitch 2.2.x and 2.3.x, the MPLS buffer overflow can be exploited for arbitrary remote code execution.
In Open vSwitch 2.4.x, the MPLS buffer overflow does not obviously lead to a remote code execution exploit, but testing shows that it can allow a remote denial of service. See the mitigation section for details.
Open vSwitch 2.5.x is not vulnerable.

Logstash developers report:
Passwords Printed in Log Files under Some Conditions
It was discovered that, in Logstash 2.1.0+, log messages generated by a stalled pipeline during shutdown will print plaintext contents of password fields. While investigating this issue we also discovered that debug logging has included this data for quite some time. Our latest releases fix both leaks. You will want to scrub old log files if this is of particular concern to you. This was fixed in issue #4965
Subversion project reports:
svnserve, the svn:// protocol server, can optionally use the Cyrus SASL library for authentication, integrity protection, and encryption. Due to a programming oversight, authentication against Cyrus SASL would permit the remote user to specify a realm string which is a prefix of the expected realm string.
Subversion's httpd servers are vulnerable to a remotely triggerable crash in the mod_authz_svn module. The crash can occur during an authorization check for a COPY or MOVE request with a specially crafted header value.
This allows remote attackers to cause a denial of service.

Squid security advisory 2016:5 reports:
Due to incorrect buffer management Squid cachemgr.cgi tool is vulnerable to a buffer overflow when processing remotely supplied inputs relayed to it from Squid.
This problem allows any client to seed the Squid manager reports with data that will cause a buffer overflow when processed by the cachemgr.cgi tool. However, this does require manual administrator actions to take place. Which greatly reduces the impact and possible uses.
Squid security advisory 2016:6 reports:
Due to buffer overflow issues Squid is vulnerable to a denial of service attack when processing ESI responses. Due to incorrect input validation Squid is vulnerable to public information disclosure of the server stack layout when processing ESI responses. Due to incorrect input validation and buffer overflow Squid is vulnerable to remote code execution when processing ESI responses.
These problems allow ESI components to be used to perform a denial of service attack on the Squid service and all other services on the same machine. Under certain build conditions these problems allow remote clients to view large sections of the server memory. However, the bugs are exploitable only if you have built and configured the ESI features to be used by a reverse-proxy and if the ESI components being processed by Squid can be controlled by an attacker.

MITRE reports:
The get_option function in dhcp.c in dhcpcd before 6.2.0, as used in dhcpcd 5.x in Android before 5.1 and other products, does not validate the relationship between length fields and the amount of data, which allows remote DHCP servers to execute arbitrary code or cause a denial of service (memory corruption) via a large length value of an option in a DHCPACK message.
MITRE reports:
The print_option function in dhcp-common.c in dhcpcd through 6.9.1, as used in dhcp.c in dhcpcd 5.x in Android before 5.1 and other products, misinterprets the return value of the snprintf function, which allows remote DHCP servers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted message.
The Asterisk project reports:
PJProject has a limit on the number of TCP connections that it can accept. Furthermore, PJProject does not close TCP connections it accepts. By default, this value is approximately 60.
An attacker can deplete the number of allowed TCP connections by opening TCP connections and sending no data to Asterisk.
If PJProject has been compiled in debug mode, then once the number of allowed TCP connections has been depleted, the next attempted TCP connection to Asterisk will crash due to an assertion in PJProject.
If PJProject has not been compiled in debug mode, then any further TCP connection attempts will be rejected. This makes Asterisk unable to process TCP SIP traffic.
Note that this only affects TCP/TLS, since UDP is connectionless.
The Asterisk project reports:
Asterisk may crash when processing an incoming REGISTER request if that REGISTER contains a Contact header with a lengthy URI.
This crash will only happen for requests that pass authentication. Unauthenticated REGISTER requests will not result in a crash occurring.
This vulnerability only affects Asterisk when using PJSIP as its SIP stack. The chan_sip module does not have this problem.
Jason Buberel reports:
Go has an infinite loop in several big integer routines that makes Go programs vulnerable to remote denial of service attacks. Programs using HTTPS client authentication or the Go ssh server libraries are both exposed to this vulnerability.
Samba team reports:
[CVE-2015-5370] Errors in Samba DCE-RPC code can lead to denial of service (crashes and high cpu consumption) and man in the middle attacks.
[CVE-2016-2110] The feature negotiation of NTLMSSP is not downgrade protected. A man in the middle is able to clear even required flags, especially NTLMSSP_NEGOTIATE_SIGN and NTLMSSP_NEGOTIATE_SEAL.
[CVE-2016-2111] When Samba is configured as Domain Controller it allows remote attackers to spoof the computer name of a secure channel's endpoints, and obtain sensitive session information, by running a crafted application and leveraging the ability to sniff network traffic.
[CVE-2016-2112] A man in the middle is able to downgrade LDAP connections to no integrity protection.
[CVE-2016-2113] Man in the middle attacks are possible for client triggered LDAP connections (with ldaps://) and ncacn_http connections (with https://).
[CVE-2016-2114] Due to a bug Samba doesn't enforce required smb signing, even if explicitly configured.
[CVE-2016-2115] The protection of DCERPC communication over ncacn_np (which is the default for most the file server related protocols) is inherited from the underlying SMB connection.
[CVE-2016-2118] a.k.a. BADLOCK. A man in the middle can intercept any DCERPC traffic between a client and a server in order to impersonate the client and get the same privileges as the authenticated user account. This is most problematic against active directory domain controllers.

Squid security advisory 2016:3 reports:
Due to a buffer overrun Squid pinger binary is vulnerable to denial of service or information leak attack when processing ICMPv6 packets.
This bug also permits the server response to manipulate other ICMP and ICMPv6 queries processing to cause information leak.
This bug allows any remote server to perform a denial of service attack on the Squid service by crashing the pinger. This may affect Squid HTTP routing decisions. In some configurations, sub-optimal routing decisions may result in serious service degradation or even transaction failures.
If the system does not contain buffer-overrun protection leading to that crash this bug will instead allow attackers to leak arbitrary amounts of information from the heap into Squid log files. This is of higher importance than usual because the pinger process operates with root priviliges.
Squid security advisory 2016:4 reports:
Due to incorrect bounds checking Squid is vulnerable to a denial of service attack when processing HTTP responses.
This problem allows a malicious client script and remote server delivering certain unusual HTTP response syntax to trigger a denial of service for all clients accessing the Squid service.
PostgreSQL project reports:
Security Fixes for RLS, BRIN
This release closes security hole CVE-2016-2193 (https://access.redhat.com/security/cve/CVE-2016-2193), where a query plan might get reused for more than one ROLE in the same session. This could cause the wrong set of Row Level Security (RLS) policies to be used for the query.
The update also fixes CVE-2016-3065 (https://access.redhat.com/security/cve/CVE-2016-3065), a server crash bug triggered by using `pageinspect` with BRIN index pages. Since an attacker might be able to expose a few bytes of server memory, this crash is being treated as a security issue.

The botan developers reports:
Infinite loop in modular square root algorithm - The ressol function implements the Tonelli-Shanks algorithm for finding square roots could be sent into a nearly infinite loop due to a misplaced conditional check. This could occur if a composite modulus is provided, as this algorithm is only defined for primes. This function is exposed to attacker controlled input via the OS2ECP function during ECC point decompression.
Heap overflow on invalid ECC point - The PointGFp constructor did not check that the affine coordinate arguments were less than the prime, but then in curve multiplication assumed that both arguments if multiplied would fit into an integer twice the size of the prime.
The bigint_mul and bigint_sqr functions received the size of the output buffer, but only used it to dispatch to a faster algorithm in cases where there was sufficient output space to call an unrolled multiplication function.
The result is a heap overflow accessible via ECC point decoding, which accepted untrusted inputs. This is likely exploitable for remote code execution.
On systems which use the mlock pool allocator, it would allow an attacker to overwrite memory held in secure_vector objects. After this point the write will hit the guard page at the end of the mmapped region so it probably could not be used for code execution directly, but would allow overwriting adjacent key material.
The botan developers reports:
Excess memory allocation in BER decoder - The BER decoder would allocate a fairly arbitrary amount of memory in a length field, even if there was no chance the read request would succeed. This might cause the process to run out of memory or invoke the OOM killer.
Crash in BER decoder - The BER decoder would crash due to reading from offset 0 of an empty vector if it encountered a BIT STRING which did not contain any data at all. This can be used to easily crash applications reading untrusted ASN.1 data, but does not seem exploitable for code execution.

Alvaro Muatoz, Matthias Kaiser and Christian Schneider reports:
JMS Object messages depends on Java Serialization for marshaling/unmashaling of the message payload. There are a couple of places inside the broker where deserialization can occur, like web console or stomp object message transformation. As deserialization of untrusted data can lead to security flaws as demonstrated in various reports, this leaves the broker vulnerable to this attack vector. Additionally, applications that consume ObjectMessage type of messages can be vulnerable as they deserialize objects on ObjectMessage.getObject() calls.
Michael Furman reports:
The web based administration console does not set the X-Frame-Options header in HTTP responses. This allows the console to be embedded in a frame or iframe which could then be used to cause a user to perform an unintended action in the console.

The OpenSSH project reports:
Missing sanitisation of untrusted input allows an authenticated user who is able to request X11 forwarding to inject commands to xauth(1).
Injection of xauth commands grants the ability to read arbitrary files under the authenticated user's privilege, Other xauth commands allow limited information leakage, file overwrite, port probing and generally expose xauth(1), which was not written with a hostile user in mind, as an attack surface.
Mitigation:
Set X11Forwarding=no in sshd_config. This is the default.
For authorized_keys that specify a "command" restriction, also set the "restrict" (available in OpenSSH >=7.2) or "no-x11-forwarding" restrictions.

Mozilla Foundation reports:
Security researcher Holger Fuhrmannek and Mozilla security engineer Tyson Smith reported a number of security vulnerabilities in the Graphite 2 library affecting version 1.3.5. The issue reported by Holger Fuhrmannek is a mechanism to induce stack corruption with a malicious graphite font. This leads to a potentially exploitable crash when the font is loaded. Tyson Smith used the Address Sanitizer tool in concert with a custom software fuzzer to find a series of uninitialized memory, out-of-bounds read, and out-of-bounds write errors when working with fuzzed graphite fonts.
Security researcher James Clawson used the Address Sanitizer tool to discover an out-of-bounds write in the Graphite 2 library when loading a crafted Graphite font file. This results in a potentially exploitable crash.
Mozilla Foundation reports:

Andreas Schneider reports:
libssh versions 0.1 and above have a bits/bytes confusion bug and generate an abnormally short ephemeral secret for the diffie-hellman-group1 and diffie-hellman-group14 key exchange methods. The resulting secret is 128 bits long, instead of the recommended sizes of 1024 and 2048 bits respectively. There are practical algorithms (Baby steps/Giant steps, Pollard’s rho) that can solve this problem in O(2^63) operations.
Both client and server are are vulnerable, pre-authentication. This vulnerability could be exploited by an eavesdropper with enough resources to decrypt or intercept SSH sessions. The bug was found during an internal code review by Aris Adamantiadis of the libssh team.

The Apache Software Foundation reports:
The Xerces-C XML parser mishandles certain kinds of malformed input documents, resulting in buffer overflows during processing and error reporting. The overflows can manifest as a segmentation fault or as memory corruption during a parse operation. The bugs allow for a denial of service attack in many applications by an unauthenticated attacker, and could conceivably result in remote code execution.
Tim Graham reports:
User with "change" but not "add" permission can create objects for ModelAdmin’s with save_as=True
The Xen Project reports:
VMX refuses attempts to enter a guest with an instruction pointer which doesn't satisfy certain requirements. In particular, the instruction pointer needs to be canonical when entering a guest currently in 64-bit mode. This is the case even if the VM entry information specifies an exception to be injected immediately (in which case the bad instruction pointer would possibly never get used for other than pushing onto the exception handler's stack). Provided the guest OS allows user mode to map the virtual memory space immediately below the canonical/non-canonical address boundary, a non-canonical instruction pointer can result even from normal user mode execution. VM entry failure, however, is fatal to the guest.
Malicious HVM guest user mode code may be able to crash the guest.
The Xen Project reports:
While INVLPG does not cause a General Protection Fault when used on a non-canonical address, INVVPID in its "individual address" variant, which is used to back the intercepted INVLPG in certain cases, fails in such cases. Failure of INVVPID results in a hypervisor bug check.
A malicious guest can crash the host, leading to a Denial of Service.
The Xen Project reports:
The PV superpage functionality lacks certain validity checks on data being passed to the hypervisor by guests. This is the case for the page identifier (MFN) passed to MMUEXT_MARK_SUPER and MMUEXT_UNMARK_SUPER sub-ops of the HYPERVISOR_mmuext_op hypercall as well as for various forms of page table updates.
Use of the feature, which is disabled by default, may have unknown effects, ranging from information leaks through Denial of Service to privilege escalation.

Jenkins Security Advisory:
Description
SECURITY-232 / CVE-2016-0788(Remote code execution vulnerability in remoting module)
A vulnerability in the Jenkins remoting module allowed unauthenticated remote attackers to open a JRMP listener on the server hosting the Jenkins master process, which allowed arbitrary code execution.
SECURITY-238 / CVE-2016-0789(HTTP response splitting vulnerability)
An HTTP response splitting vulnerability in the CLI command documentation allowed attackers to craft Jenkins URLs that serve malicious content.
SECURITY-241 / CVE-2016-0790(Non-constant time comparison of API token)
The verification of user-provided API tokens with the expected value did not use a constant-time comparison algorithm, potentially allowing attackers to use statistical methods to determine valid API tokens using brute-force methods.
SECURITY-245 / CVE-2016-0791(Non-constant time comparison of CSRF crumbs)
The verification of user-provided CSRF crumbs with the expected value did not use a constant-time comparison algorithm, potentially allowing attackers to use statistical methods to determine valid CSRF crumbs using brute-force methods.
SECURITY-247 / CVE-2016-0792(Remote code execution through remote API)
Jenkins has several API endpoints that allow low-privilege users to POST XML files that then get deserialized by Jenkins. Maliciously crafted XML files sent to these API endpoints could result in arbitrary code execution.
Squid security advisory 2016:2 reports:
Due to incorrect bounds checking Squid is vulnerable to a denial of service attack when processing HTTP responses.
These problems allow remote servers delivering certain unusual HTTP response syntax to trigger a denial of service for all clients accessing the Squid service.
HTTP responses containing malformed headers that trigger this issue are becoming common. We are not certain at this time if that is a sign of malware or just broken server scripting.
Stian Soiland-Reyes reports:
This release fixes a remote code execution vulnerability that was identified in BeanShell by Alvaro Muñoz and Christian Schneider. The BeanShell team would like to thank them for their help and contributions to this fix!
An application that includes BeanShell on the classpath may be vulnerable if another part of the application uses Java serialization or XStream to deserialize data from an untrusted source.
A vulnerable application could be exploited for remote code execution, including executing arbitrary shell commands.
This update fixes the vulnerability in BeanShell, but it is worth noting that applications doing such deserialization might still be insecure through other libraries. It is recommended that application developers take further measures such as using a restricted class loader when deserializing. See notes on Java serialization security XStream security and How to secure deserialization from untrusted input without using encryption or sealing.

[583431] Critical CVE-2016-1629: Same-origin bypass in Blink and Sandbox escape in Chrome. Credit to anonymous.
Fabio Olive Leite reports:
A stack-based buffer overflow was found in libresolv when invoked from nss_dns, allowing specially crafted DNS responses to seize control of EIP in the DNS client. The buffer overflow occurs in the functions send_dg (send datagram) and send_vc (send TCP) for the NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC family, or in some cases AF_INET6 family. The use of AF_UNSPEC (or AF_INET6 in some cases) triggers the low-level resolver code to send out two parallel queries for A and AAAA. A mismanagement of the buffers used for those queries could result in the response of a query writing beyond the alloca allocated buffer created by __res_nquery.
Squid security advisory 2016:1 reports:
Due to incorrectly handling server errors Squid is vulnerable to a denial of service attack when connecting to TLS or SSL servers.
This problem allows any trusted client to perform a denial of service attack on the Squid service regardless of whether TLS or SSL is configured for use in the proxy.
Misconfigured client or server software may trigger this issue to perform a denial of service unintentionally.
However, the bug is exploitable only if Squid is built using the --with-openssl option.
The FreeBSD port does not use SSL by default and is not vulnerable in the default configuration.

The Pillow maintainers report:
In all versions of Pillow, dating back at least to the last PIL 1.1.7 release, PcdDecode.c has a buffer overflow error.
The state.buffer for PcdDecode.c is allocated based on a 3 bytes per pixel sizing, where PcdDecode.c wrote into the buffer assuming 4 bytes per pixel. This writes 768 bytes beyond the end of the buffer into other Python object storage. In some cases, this causes a segfault, in others an internal Python malloc error.
The Pillow maintainers report:
If a large value was passed into the new size for an image, it is possible to overflow an int32 value passed into malloc, leading the malloc’d buffer to be undersized. These allocations are followed by a loop that writes out of bounds. This can lead to corruption on the heap of the Python process with attacker controlled float data.
This issue was found by Ned Williamson.
The Pillow maintainers report:
In all versions of Pillow, dating back at least to the last PIL 1.1.7 release, FliDecode.c has a buffer overflow error.
There is a memcpy error where x is added to a target buffer address. X is used in several internal temporary variable roles, but can take a value up to the width of the image. Im->image[y] is a set of row pointers to segments of memory that are the size of the row. At the max y, this will write the contents of the line off the end of the memory buffer, causing a segfault.
This issue was found by Alyssa Besseling at Atlassian.
The Pillow maintainers report:
Pillow 3.1.0 and earlier when linked against libtiff >= 4.0.0 on x64 may overflow a buffer when reading a specially crafted tiff file.
Specifically, libtiff >= 4.0.0 changed the return type of TIFFScanlineSize from int32 to machine dependent int32|64. If the scanline is sized so that it overflows an int32, it may be interpreted as a negative number, which will then pass the size check in TiffDecode.c line 236. To do this, the logical scanline size has to be > 2gb, and for the test file, the allocated buffer size is 64k against a roughly 4gb scan line size. Any image data over 64k is written over the heap, causing a segfault.
This issue was found by security researcher FourOne.

Michael Catanzaro reports:
Shotwell has a serious security issue ("Shotwell does not verify TLS certificates"). Upstream is no longer active and I do not expect any further upstream releases unless someone from the community steps up to maintain it.
What is the impact of the issue? If you ever used any of the publish functionality (publish to Facebook, publish to Flickr, etc.), your passwords may have been stolen; changing them is not a bad idea.
What is the risk of the update? Regressions. The easiest way to validate TLS certificates was to upgrade WebKit; it seems to work but I don't have accounts with the online services it supports, so I don't know if photo publishing still works properly on all the services.

socat reports:
In the OpenSSL address implementation the hard coded 1024 bit DH p parameter was not prime. The effective cryptographic strength of a key exchange using these parameters was weaker than the one one could get by using a prime p. Moreover, since there is no indication of how these parameters were chosen, the existence of a trapdoor that makes possible for an eavesdropper to recover the shared secret from a key exchange that uses them cannot be ruled out.

The Prosody team reports:
Adopt key generation algorithm from XEP-0185, to prevent impersonation attacks (CVE-2016-0756)
OpenSSL project reports:
- Historically OpenSSL only ever generated DH parameters based on "safe" primes. More recently (in version 1.0.2) support was provided for generating X9.42 style parameter files such as those required for RFC 5114 support. The primes used in such files may not be "safe". Where an application is using DH configured with parameters based on primes that are not "safe" then an attacker could use this fact to find a peer's private DH exponent. This attack requires that the attacker complete multiple handshakes in which the peer uses the same private DH exponent. For example this could be used to discover a TLS server's private DH exponent if it's reusing the private DH exponent or it's using a static DH ciphersuite. OpenSSL provides the option SSL_OP_SINGLE_DH_USE for ephemeral DH (DHE) in TLS. It is not on by default. If the option is not set then the server reuses the same private DH exponent for the life of the server process and would be vulnerable to this attack. It is believed that many popular applications do set this option and would therefore not be at risk. (CVE-2016-0701)
- A malicious client can negotiate SSLv2 ciphers that have been disabled on the server and complete SSLv2 handshakes even if all SSLv2 ciphers have been disabled, provided that the SSLv2 protocol was not also disabled via SSL_OP_NO_SSLv2. (CVE-2015-3197)

So in codeconv.c there is a function for Japanese character set conversion called conv_jistoeuc(). There is no bounds checking on the output buffer, which is created on the stack with alloca() Bug can be triggered by sending an email to TAILS_luser@riseup.net or whatever. Since my C is completely rusty, you might be able to make a better judgment on the severity of this issue. Marking critical for now.
MITRE reports:
Integer signedness error in the archive_write_zip_data function in archive_write_set_format_zip.c in libarchive 3.1.2 and earlier, when running on 64-bit machines, allows context-dependent attackers to cause a denial of service (crash) via unspecified vectors, which triggers an improper conversion between unsigned and signed types, leading to a buffer overflow.
Absolute path traversal vulnerability in bsdcpio in libarchive 3.1.2 and earlier allows remote attackers to write to arbitrary files via a full pathname in an archive.
Libarchive issue tracker reports:
Using a crafted tar file bsdtar can perform an out-of-bounds memory read which will lead to a SEGFAULT. The issue exists when the executable skips data in the archive. The amount of data to skip is defined in byte offset [16-19] If ASLR is disabled, the issue can lead to an infinite loop.
Jason Buberel reports:
A security-related issue has been reported in Go's math/big package. The issue was introduced in Go 1.5. We recommend that all users upgrade to Go 1.5.3, which fixes the issue. Go programs must be recompiled with Go 1.5.3 in order to receive the fix.
The Go team would like to thank Nick Craig-Wood for identifying the issue.
This issue can affect RSA computations in crypto/rsa, which is used by crypto/tls. TLS servers on 32-bit systems could plausibly leak their RSA private key due to this issue. Other protocol implementations that create many RSA signatures could also be impacted in the same way.
Specifically, incorrect results in one part of the RSA Chinese Remainder computation can cause the result to be incorrect in such a way that it leaks one of the primes. While RSA blinding should prevent an attacker from crafting specific inputs that trigger the bug, on 32-bit systems the bug can be expected to occur at random around one in 2^26 times. Thus collecting around 64 million signatures (of known data) from an affected server should be enough to extract the private key used.
On 64-bit systems, the frequency of the bug is so low (less than one in 2^50) that it would be very difficult to exploit. Nonetheless, everyone is strongly encouraged to upgrade.
ISC reports:
A badly formed packet with an invalid IPv4 UDP length field can cause a DHCP server, client, or relay program to terminate abnormally.
Tomas Hoger reports:
A buffer overflow flaw was discovered in the libproxy's url::get_pac() used to download proxy.pac proxy auto-configuration file. A malicious host hosting proxy.pac, or a man in the middle attacker, could use this flaw to trigger a stack-based buffer overflow in an application using libproxy, if proxy configuration instructed it to download proxy.pac file from a remote HTTP server.
Arch Linux reports:
ffmpeg has a vulnerability in the current version that allows the attacker to create a specially crafted video file, downloading which will send files from a user PC to a remote attacker server. The attack does not even require the user to open that file — for example, KDE Dolphin thumbnail generation is enough.

NTF's NTP Project has been notified of the following 1 medium-severity vulnerability that is fixed in ntp-4.2.8p5, released on Thursday, 7 January 2016:
NtpBug2956: Small-step/Big-step CVE-2015-5300

ARM Limited reports:
MD5 handshake signatures in TLS 1.2 are vulnerable to the SLOTH attack on TLS 1.2 server authentication. They have been disabled by default. Other attacks from the SLOTH paper do not apply to any version of mbed TLS or PolarSSL.
The Xen Project reports:
Single memory accesses in source code can be translated to multiple ones in machine code by the compiler, requiring special caution when accessing shared memory. Such precaution was missing from the hypervisor code inspecting the state of I/O requests sent to the device model for assistance.
Due to the offending field being a bitfield, it is however believed that there is no issue in practice, since compilers, at least when optimizing (which is always the case for non-debug builds), should find it more expensive to extract the bit field value twice than to keep the calculated value in a register.
This vulnerability is exposed to malicious device models. In conventional Xen systems this means the qemu which service an HVM domain. On such systems this vulnerability can only be exploited if the attacker has gained control of the device model qemu via another vulnerability.
Privilege escalation, host crash (Denial of Service), and leaked information all cannot be excluded.
The Xen Project reports:
When XSAVE/XRSTOR are not in use by Xen to manage guest extended register state, the initial values in the FPU stack and XMM registers seen by the guest upon first use are those left there by the previous user of those registers.
A malicious domain may be able to leverage this to obtain sensitive information such as cryptographic keys from another domain.
The Xen Project reports:
When constructing a guest which is configured to use a PV bootloader which runs as a userspace process in the toolstack domain (e.g. pygrub) libxl creates a mapping of the files to be used as kernel and initial ramdisk when building the guest domain.
However if building the domain subsequently fails these mappings would not be released leading to a leak of virtual address space in the calling process, as well as preventing the recovery of the temporary disk files containing the kernel and initial ramdisk.
For toolstacks which manage multiple domains within the same process, an attacker who is able to repeatedly start a suitable domain (or many such domains) can cause an out-of-memory condition in the toolstack process, leading to a denial of service.
Under the same circumstances an attacker can also cause files to accumulate on the toolstack domain filesystem (usually under /var in dom0) used to temporarily store the kernel and initial ramdisk, perhaps leading to a denial of service against arbitrary other services using that filesystem.
The Xen Project reports:
Error handling in the operation may involve handing back pages to the domain. This operation may fail when in parallel the domain gets torn down. So far this failure unconditionally resulted in the host being brought down due to an internal error being assumed. This is CVE-2015-8339.
Furthermore error handling so far wrongly included the release of a lock. That lock, however, was either not acquired or already released on all paths leading to the error handling sequence. This is CVE-2015-8340.
A malicious guest administrator may be able to deny service by crashing the host or causing a deadlock.
zzf of Alibaba discovered an out-of-bounds vulnerability in the code processing the LogLUV and CIE Lab image format files. An attacker could create a specially-crafted TIFF file that could cause libtiff to crash.
LMX of Qihoo 360 Codesafe Team discovered an out-of-bounds read in tif_getimage.c. An attacker could create a specially-crafted TIFF file that could cause libtiff to crash.
Gustavo Grieco reports:
Two issues were found in unzip 6.0:
* A heap overflow triggered by unzipping a file with password (e.g unzip -p -P x sigsegv.zip).
* A denegation of service with a file that never finishes unzipping (e.g. unzip sigxcpu.zip).
NVD reports:
SQL injection vulnerability in include/top_graph_header.php in Cacti 0.8.8f and earlier allows remote attackers to execute arbitrary SQL commands via the rra_id parameter in a properties action to graph.php.
ISC Support reports:
ISC Kea may terminate unexpectedly (crash) while handling a malformed client packet. Related defects in the kea-dhcp4 and kea-dhcp6 servers can cause the server to crash during option processing if a client sends a malformed packet. An attacker sending a crafted malformed packet can cause an ISC Kea server providing DHCP services to IPv4 or IPv6 clients to exit unexpectedly.
The kea-dhcp4 server is vulnerable only in versions 0.9.2 and 1.0.0-beta, and furthermore only when logging at debug level 40 or higher. Servers running kea-dhcp4 versions 0.9.1 or lower, and servers which are not logging or are logging at debug level 39 or below are not vulnerable.
The kea-dhcp6 server is vulnerable only in versions 0.9.2 and 1.0.0-beta, and furthermore only when logging at debug level 45 or higher. Servers running kea-dhcp6 versions 0.9.1 or lower, and servers which are not logging or are logging at debug level 44 or below are not vulnerable.
ACME Updates reports:
mini_httpd 1.21 and earlier allows remote attackers to obtain sensitive information from process memory via an HTTP request with a long protocol string, which triggers an incorrect response size calculation and an out-of-bounds read.

Prasad J Pandit, Red Hat Product Security Team, reports:
Qemu emulator built with the AMD PC-Net II Ethernet Controller support is vulnerable to a heap buffer overflow flaw. While receiving packets in the loopback mode, it appends CRC code to the receive buffer. If the data size given is same as the receive buffer size, the appended CRC code overwrites 4 bytes beyond this 's->buffer' array.
A privileged(CAP_SYS_RAWIO) user inside guest could use this flaw to crash the Qemu instance resulting in DoS or potentially execute arbitrary code with privileges of the Qemu process on the host.
The AMD PC-Net II emulator(hw/net/pcnet.c), while receiving packets from a remote host(non-loopback mode), fails to validate the received data size, thus resulting in a buffer overflow issue. It could potentially lead to arbitrary code execution on the host, with privileges of the Qemu process. It requires the guest NIC to have larger MTU limit.
A remote user could use this flaw to crash the guest instance resulting in DoS or potentially execute arbitrary code on a remote host with privileges of the Qemu process.
Prasad J Pandit, Red Hat Product Security Team, reports:
Qemu emulator built with the i8255x (PRO100) emulation support is vulnerable to an infinite loop issue. It could occur while processing a chain of commands located in the Command Block List (CBL). Each Command Block(CB) points to the next command in the list. An infinite loop unfolds if the link to the next CB points to the same block or there is a closed loop in the chain.
A privileged(CAP_SYS_RAWIO) user inside guest could use this flaw to crash the Qemu instance resulting in DoS.
Prasad J Pandit, Red Hat Product Security Team, reports:
Qemu emulator built with the Virtual Network Device(virtio-net) support is vulnerable to a DoS issue. It could occur while receiving large packets over the tuntap/macvtap interfaces and when guest's virtio-net driver did not support big/mergeable receive buffers.
An attacker on the local network could use this flaw to disable guest's networking by sending a large number of jumbo frames to the guest, exhausting all receive buffers and thus leading to a DoS situation.
Prasad J Pandit, Red Hat Product Security Team, reports:
Qemu emulator built with the NE2000 NIC emulation support is vulnerable to an infinite loop issue. It could occur when receiving packets over the network.
A privileged user inside guest could use this flaw to crash the Qemu instance resulting in DoS.

Prasad J Pandit, Red Hat Product Security Team, reports:
Qemu emulator built with the VNC display driver support is vulnerable to a buffer overflow flaw leading to a heap memory corruption issue. It could occur while refreshing the server display surface via routine vnc_refresh_server_surface().
A privileged guest user could use this flaw to corrupt the heap memory and crash the Qemu process instance OR potentially use it to execute arbitrary code on the host.
Prasad J Pandit, Red Hat Product Security Team, reports:
Qemu emulator built with the virtio-serial vmchannel support is vulnerable to a buffer overflow issue. It could occur while exchanging virtio control messages between guest and the host.
A malicious guest could use this flaw to corrupt few bytes of Qemu memory area, potentially crashing the Qemu process.
Prasad J Pandit, Red Hat Product Security Team, reports:
Qemu emulator built with the SCSI device emulation support is vulnerable to a stack buffer overflow issue. It could occur while parsing SCSI command descriptor block with an invalid operation code.
A privileged(CAP_SYS_RAWIO) user inside guest could use this flaw to crash the Qemu instance resulting in DoS.
Petr Matousek of Red Hat Inc. reports:
Due converting PIO to the new memory read/write api we no longer provide separate I/O region lenghts for read and write operations. As a result, reading from PIT Mode/Command register will end with accessing pit->channels with invalid index and potentially cause memory corruption and/or minor information leak.
A privileged guest user in a guest with QEMU PIT emulation enabled could potentially (tough unlikely) use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process.
Please note that by default QEMU/KVM guests use in-kernel (KVM) PIT emulation and are thus not vulnerable to this issue.

NVD reports:
The ff_dwt_decode function in libavcodec/jpeg2000dwt.c in FFmpeg before 2.8.4 does not validate the number of decomposition levels before proceeding with Discrete Wavelet Transform decoding, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data.
The ff_get_buffer function in libavcodec/utils.c in FFmpeg before 2.8.4 preserves width and height values after a failure, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted .mov file.
The Mozilla Project reports:
Security researcher Karthikeyan Bhargavan reported an issue in Network Security Services (NSS) where MD5 signatures in the server signature within the TLS 1.2 ServerKeyExchange message are still accepted. This is an issue since NSS has officially disallowed the accepting MD5 as a hash algorithm in signatures since 2011. This issues exposes NSS based clients such as Firefox to theoretical collision-based forgery attacks.
The phpMyAdmin development team reports:
By calling some scripts that are part of phpMyAdmin in an unexpected way, it is possible to trigger phpMyAdmin to display a PHP error message which contains the full path of the directory where phpMyAdmin is installed.
We consider these vulnerabilities to be non-critical.
This path disclosure is possible on servers where the recommended setting of the PHP configuration directive display_errors is set to on, which is against the recommendations given in the PHP manual for a production server.

Bugzilla Security Advisory
During the generation of a dependency graph, the code for the HTML image map is generated locally if a local dot installation is used. With escaped HTML characters in a bug summary, it is possible to inject unfiltered HTML code in the map file which the CreateImagemap function generates. This could be used for a cross-site scripting attack.
If an external HTML page contains a <script> element with its src attribute pointing to a buglist in CSV format, some web browsers incorrectly try to parse the CSV file as valid JavaScript code. As the buglist is generated based on the privileges of the user logged into Bugzilla, the external page could collect confidential data contained in the CSV file.

Pierre Schweitzer reports:
Any client sending the command "/op *" in a query will cause the Quassel core to crash.
Libvit development team reports:
Various virStorageVol* API operate on user-supplied volume names by concatenating the volume name to the pool location. Note that the virStoragePoolListVolumes API, when used on a storage pool backed by a directory in a file system, will only list volumes immediately in that directory (there is no traversal into subdirectories). However, other APIs such as virStorageVolCreateXML were not checking if a potential volume name represented one of the volumes that could be returned by virStoragePoolListVolumes; because they were not rejecting the use of '/' in a volume name.
Because no checking was done on volume names, a user could supply a potential volume name of something like '../../../etc/passwd' to attempt to access a file not belonging to the storage pool. When fine-grained Access Control Lists (ACL) are in effect, a user with storage_vol:create ACL permission but lacking domain:write permission could thus abuse virStorageVolCreateXML and similar APIs to gain access to files not normally permitted to that user. Fortunately, it appears that the only APIs that could leak information or corrupt files require read-write connection to libvirtd; and when ACLs are not in use (the default without any further configuration), a user with read-write access can already be considered to have full access to the machine, and without an escalation of privilege there is no security problem.

Jenkins Security Advisory:
Description
SECURITY-95 / CVE-2015-7536 (Stored XSS vulnerability through workspace files and archived artifacts)
In certain configurations, low privilege users were able to create e.g. HTML files in workspaces and archived artifacts that could result in XSS when accessed by other users. Jenkins now sends Content-Security-Policy headers that enables sandboxing and prohibits script execution by default.
SECURITY-225 / CVE-2015-7537 (CSRF vulnerability in some administrative actions)
Several administration/configuration related URLs could be accessed using GET, which allowed attackers to circumvent CSRF protection.
SECURITY-233 / CVE-2015-7538 (CSRF protection ineffective)
Malicious users were able to circumvent CSRF protection on any URL by sending specially crafted POST requests.
SECURITY-234 / CVE-2015-7539 (Jenkins plugin manager vulnerable to MITM attacks)
While the Jenkins update site data is digitally signed, and the signature verified by Jenkins, Jenkins did not verify the provided SHA-1 checksums for the plugin files referenced in the update site data. This enabled MITM attacks on the plugin manager, resulting in installation of attacker-provided plugins.

Daniel Knoppel reports:
It was discovered by the SUSE security team that it was possible, in some cases, for clients to overwrite headers set by the server, resulting in a medium level security issue. CVE-2015-7519 has been assigned to this issue.
Affected use-cases:
Header overwriting may occur if all of the following conditions are met:
- Apache integration mode, or standalone+builtin engine without a filtering proxy
- Ruby or Python applications only (Passenger 5); or any application (Passenger 4)
- The app depends on a request header containing a dash (-)
- The header is supposed to be trusted (set by the server)
- The client correctly guesses the header name
This vulnerability has been fixed by filtering out client headers that do not consist of alphanumeric/dash characters (Nginx already did this, so Passenger+Nginx was not affected). If your application depends on headers that don't conform to this, you can add a workaround in Apache specifically for those to convert them to a dash-based format.

NVD reports:
The update_dimensions function in libavcodec/vp8.c in FFmpeg through 2.8.1, as used in Google Chrome before 46.0.2490.71 and other products, relies on a coefficient-partition count during multi-threaded operation, which allows remote attackers to cause a denial of service (race condition and memory corruption) or possibly have unspecified other impact via a crafted WebM file.
The ljpeg_decode_yuv_scan function in libavcodec/mjpegdec.c in FFmpeg before 2.8.2 omits certain width and height checks, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted MJPEG data.
The ff_hevc_parse_sps function in libavcodec/hevc_ps.c in FFmpeg before 2.8.2 does not validate the Chroma Format Indicator, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted High Efficiency Video Coding (HEVC) data.
The decode_uncompressed function in libavcodec/faxcompr.c in FFmpeg before 2.8.2 does not validate uncompressed runs, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted CCITT FAX data.
The init_tile function in libavcodec/jpeg2000dec.c in FFmpeg before 2.8.2 does not enforce minimum-value and maximum-value constraints on tile coordinates, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data.
The jpeg2000_read_main_headers function in libavcodec/jpeg2000dec.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not enforce uniqueness of the SIZ marker in a JPEG 2000 image, which allows remote attackers to cause a denial of service (out-of-bounds heap-memory access) or possibly have unspecified other impact via a crafted image with two or more of these markers.
Integer overflow in the ff_ivi_init_planes function in libavcodec/ivi.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 allows remote attackers to cause a denial of service (out-of-bounds heap-memory access) or possibly have unspecified other impact via crafted image dimensions in Indeo Video Interactive data.
The smka_decode_frame function in libavcodec/smacker.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not verify that the data size is consistent with the number of channels, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Smacker data.

The Xen Project reports:
A malicious HVM guest administrator can cause a denial of service. Specifically, prevent use of a physical CPU for a significant, perhaps indefinite period. If a host watchdog (Xen or dom0) is in use, this can lead to a watchdog timeout and consequently a reboot of the host. If another, innocent, guest, is configured with a watchdog, this issue can lead to a reboot of such a guest.

owncloud.org reports:
The ownCloud Desktop Client was vulnerable against MITM attacks until version 2.0.0 in combination with self-signed certificates.
The Xen Project reports:
Guests configured with PoD might be unstable, especially under load. In an affected guest, an unprivileged guest user might be able to cause a guest crash, perhaps simply by applying load so as to cause heavy memory pressure within the guest.
The Xen Project reports:
HYPERCALL_xenoprof_op and HYPERVISOR_xenpmu_op log some errors and attempts at invalid operations. These log messages are not rate-limited, even though they can be triggered by guests.
A malicious guest could cause repeated logging to the hypervisor console, leading to a Denial of Service attack.
The Xen Project reports:
A domain's xenoprofile state contains an array of per-vcpu information... This array is leaked on domain teardown. This memory leak could -- over time -- exhaust the host's memory.
The following parties can mount a denial of service attack affecting the whole system:
- A malicious guest administrator via XENOPROF_get_buffer.
- A domain given suitable privilege over another domain via XENOPROF_set_passive (this would usually be a domain being used to profile another domain, eg with the xenoprof tool).
The ability to also restart or create suitable domains is also required to fully exploit the issue. Without this the leak is limited to a small multiple of the maximum number of vcpus for the domain.
The Xen Project reports:
When running an HVM domain in Populate-on-Demand mode, Xen would sometimes search the domain for memory to reclaim, in response to demands for population of other pages in the same domain. This search runs without preemption. The guest can, by suitable arrangement of its memory contents, create a situation where this search is a time-consuming linear scan of the guest's address space.
A malicious HVM guest administrator can cause a denial of service. Specifically, prevent use of a physical CPU for a significant period.
The Xen Project reports:
A domain's primary array of vcpu pointers can be allocated by a toolstack exactly once in the lifetime of a domain via the XEN_DOMCTL_max_vcpus hypercall. This array is leaked on domain teardown. This memory leak could -- over time -- exhaust the host's memory.
A domain given partial management control via XEN_DOMCTL_max_vcpus can mount a denial of service attack affecting the whole system. The ability to also restart or create suitable domains is also required to fully exploit the issue. Without this the leak is limited to a small multiple of the maximum number of vcpus for the domain. The maximum leak is 64kbytes per domain (re)boot (less on ARM).
The Xen Project reports:
The code to validate level 2 page table entries is bypassed when certain conditions are satisfied. This means that a PV guest can create writable mappings using super page mappings. Such writable mappings can violate Xen intended invariants for pages which Xen is supposed to keep read-only. This is possible even if the "allowsuperpage" command line option is not used.
Malicious PV guest administrators can escalate privilege so as to control the whole system.
The Xen Project reports:
Callers of libxl can specify that a disk should be read-only to the guest. However, there is no code in libxl to pass this information to qemu-xen (the upstream-based qemu); and indeed there is no way in qemu to make a disk read-only.
The vulnerability is exploitable only via devices emulated by the device model, not the parallel PV devices for supporting PVHVM. Normally the PVHVM device unplug protocol renders the emulated devices inaccessible early in boot.
Malicious guest administrators or (in some situations) users may be able to write to supposedly read-only disk images.
CDROM devices (that is, devices specified to be presented to the guest as CDROMs, regardless of the nature of the backing storage on the host) are not affected.
MITRE reports:
Cross-site scripting (XSS) vulnerability in the HTML-Scrubber module before 0.15 for Perl, when the comment feature is enabled, allows remote attackers to inject arbitrary web script or HTML via a crafted comment.
The Mozilla Project reports:
Security researcher Khalil Zhani reported that a maliciously crafted vp9 format video could be used to trigger a buffer overflow while parsing the file. This leads to a potentially exploitable crash due to a flaw in the libvpx library.
PowerDNS reports:
A bug was found using afl-fuzz in our packet parsing code. This bug, when exploited, causes an assertion error and consequent termination of the the pdns_server process, causing a Denial of Service.
Ben Harris reports:
Versions of PuTTY and pterm between 0.54 and 0.65 inclusive have a potentially memory-corrupting integer overflow in the handling of the ECH (erase characters) control sequence in the terminal emulator.
To exploit a vulnerability in the terminal emulator, an attacker must be able to insert a carefully crafted escape sequence into the terminal stream. For a PuTTY SSH session, this must be before encryption, so the attacker likely needs access to the server you're connecting to. For instance, an attacker on a multi-user machine that you connect to could trick you into running cat on a file they control containing a malicious escape sequence. (Unix write(1) is not a vector for this, if implemented correctly.)
Only PuTTY, PuTTYtel, and pterm are affected; other PuTTY tools do not include the terminal emulator, so cannot be exploited this way.
The Apache OpenOffice Project reports:
A vulnerability in OpenOffice settings of OpenDocument Format files and templates allows silent access to files that are readable from an user account, over-riding the user's default configuration settings. Once these files are imported into a maliciously-crafted document, the data can be silently hidden in the document and possibly exported to an external party without being observed.
The Apache OpenOffice Project reports:
A crafted ODF document can be used to create a buffer that is too small for the amount of data loaded into it, allowing an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.
The Apache OpenOffice Project reports:
A crafted Microsoft Word DOC file can be used to specify a document buffer that is too small for the amount of data provided for it. Failure to detect the discrepancy allows an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.
The Apache OpenOffice Project reports:
A crafted Microsoft Word DOC can contain invalid bookmark positions leading to memory corruption when the document is loaded or bookmarks are manipulated. The defect allows an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.
The CodeIgniter changelog reports:
Fixed an XSS attack vector in Security Library method xss_clean().
Changed Config Library method base_url() to fallback to ``$_SERVER['SERVER_ADDR']`` in order to avoid Host header injections.
Changed CAPTCHA Helper to try to use the operating system's PRNG first.
The OpenAFS development team reports:
When constructing an Rx acknowledgment (ACK) packet, Andrew-derived Rx implementations do not initialize three octets of data that are padding in the C language structure and were inadvertently included in the wire protocol (CVE-2015-7762). Additionally, OpenAFS Rx in versions 1.5.75 through 1.5.78, 1.6.0 through 1.6.14, and 1.7.0 through 1.7.32 include a variable-length padding at the end of the ACK packet, in an attempt to detect the path MTU, but only four octets of the additional padding are initialized (CVE-2015-7763).
RedHat bugzilla reports:
In dual screen configurations, unplugging one screen will cause xscreensaver to crash, leaving the screen unlocked.
The lldpd developer Vincent Bernat reports:
A buffer overflow may allow arbitrary code execution only if hardening was disabled.
Malformed packets should not make lldpd crash. Ensure we can handle them by not using assert() in this part.
Wireshark development team reports:

Drupal development team reports:
The Overlay module in Drupal core displays administrative pages as a layer over the current page (using JavaScript), rather than replacing the page in the browser window. The Overlay module does not sufficiently validate URLs prior to displaying their contents, leading to an open redirect vulnerability.
This vulnerability is mitigated by the fact that it can only be used against site users who have the "Access the administrative overlay" permission, and that the Overlay module must be enabled.
An incomplete fix for this issue was released as part of SA-CORE-2015-002.
The phpMyAdmin development team reports:
This vulnerability allows an attacker to perform a content spoofing attack using the phpMyAdmin's redirection mechanism to external sites.
We consider this vulnerability to be non critical since the spoofed content is escaped and no HTML injection is possible.
MediaWiki reports:
Wikipedia user RobinHood70 reported two issues in the chunked upload API. The API failed to correctly stop adding new chunks to the upload when the reported size was exceeded (T91203), allowing a malicious users to upload add an infinite number of chunks for a single file upload. Additionally, a malicious user could upload chunks of 1 byte for very large files, potentially creating a very large number of files on the server's filesystem (T91205).
Internal review discovered that it is not possible to throttle file uploads.
Internal review discovered a missing authorization check when removing suppression from a revision. This allowed users with the 'viewsuppressed' user right but not the appropriate 'suppressrevision' user right to unsuppress revisions.
Richard Stanway from teamliquid.net reported that thumbnails of PNG files generated with ImageMagick contained the local file path in the image metadata.
ntp.org reports:

Git release notes:
Some protocols (like git-remote-ext) can execute arbitrary code found in the URL. The URLs that submodules use may come from arbitrary sources (e.g., .gitmodules files in a remote repository), and can hurt those who blindly enable recursive fetch. Restrict the allowed protocols to well known and safe ones.
Salt release notes:
CVE-2015-6918 - Git modules leaking HTTPS auth credentials to debug log
Updated the Git state and execution modules to no longer display HTTPS basic authentication credentials in loglevel debug output on the Salt master. These credentials are now replaced with REDACTED in the debug output. Thanks to Andreas Stieger for bringing this to our attention.
CVE-2015-6941 - win_useradd module and salt-cloud display passwords in debug log
Updated the win_useradd module return data to no longer include the password of the newly created user. The password is now replaced with the string XXX-REDACTED-XXX. Updated the Salt Cloud debug output to no longer display win_password and sudo_password authentication credentials. Also updated the Linode driver to no longer display authentication credentials in debug logs. These credentials are now replaced with REDACTED in the debug output.
Firefox Developers report:
Security researcher Abdulrahman Alqabandi reported that the fetch() API did not correctly implement the Cross-Origin Resource Sharing (CORS) specification, allowing a malicious page to access private data from other origins. Mozilla developer Ben Kelly independently reported the same issue.
Adobe reports:

Qualys reports:
During the code review of OpenSMTPD a memory leak and buffer overflow (an off-by-one, usually stack-based) were discovered in LibreSSL's OBJ_obj2txt() function. This function is called automatically during a TLS handshake (both client-side, unless an anonymous mode is used, and server-side, if client authentication is requested).
ARM Limited reports:
When the client creates its ClientHello message, due to insufficient bounds checking it can overflow the heap-based buffer containing the message while writing some extensions. Two extensions in particular could be used by a remote attacker to trigger the overflow: the session ticket extension and the server name indication (SNI) extension.

Matthijs Kooijman reports:
It seems that the whiptail, cdialog and kdialog backends apply some improper escaping in their shell commands, causing special characters present in menu item titles to be interpreted by the shell. This includes the backtick evaluation operator, so this constitutes a security issue, allowing execution of arbitrary commands if an attacker has control over the text displayed in a menu.
Matthias Bussonnier reports:
Summary: Local folder name was used in HTML templates without escaping, allowing XSS in said pages by carefully crafting folder name and URL to access it.
URI with issues:
- GET /tree/**
Benjamin RK reports:
Vulnerability: A maliciously forged file opened for editing can execute javascript, specifically by being redirected to /files/ due to a failure to treat the file as plain text.
URI with issues:
- GET /edit/**
PostgreSQL project reports:
Two security issues have been fixed in this release which affect users of specific PostgreSQL features.
- CVE-2015-5289 json or jsonb input values constructed from arbitrary user input can crash the PostgreSQL server and cause a denial of service.
- CVE-2015-5288: The crypt() function included with the optional pgCrypto extension could be exploited to read a few additional bytes of memory. No working exploit for this issue has been developed.
Zend Framework developers report:
The PDO adapters of Zend Framework 1 do not filter null bytes values in SQL statements. A PDO adapter can treat null bytes in a query as a string terminator, allowing an attacker to add arbitrary SQL following a null byte, and thus create a SQL injection.
OpenSMTPD developers report:
fix an mda buffer truncation bug which allows a user to create forward files that pass session checks but fail delivery later down the chain, within the user mda
fix remote buffer overflow in unprivileged pony process
reworked offline enqueue to better protect against hardlink attacks
ARM Limited reports:
Florian Weimar from Red Hat published on Lenstra's RSA-CRT attach for PKCS#1 v1.5 signatures. These releases include countermeasures against that attack.
Fabian Foerg of Gotham Digital Science found a possible client-side NULL pointer dereference, using the AFL Fuzzer. This dereference can only occur when misusing the API, although a fix has still been implemented.
ARM Limited reports:
In order to strengthen the minimum requirements for connections and to protect against the Logjam attack, the minimum size of Diffie-Hellman parameters accepted by the client has been increased to 1024 bits.
In addition the default size for the Diffie-Hellman parameters on the server are increased to 2048 bits. This can be changed with ssl_set_dh_params() in case this is necessary.
reports:
We found a heap overflow and a DoS in the gdk-pixbuf implementation triggered by the scaling of tga file.
We found a heap overflow in the gdk-pixbuf implementation triggered by the scaling of gif file.

The CodeIgniter changelog reports:
An improvement was made to the MySQL and MySQLi drivers to prevent exposing a potential vector for SQL injection on sites using multi-byte character sets in the database client connection.
An incompatibility in PHP versions < 5.2.3 and MySQL > 5.0.7 with mysql_set_charset() creates a situation where using multi-byte character sets on these environments may potentially expose a SQL injection attack vector. Latin-1, UTF-8, and other "low ASCII" character sets are unaffected on all environments.
If you are running or considering running a multi-byte character set for your database connection, please pay close attention to the server environment you are deploying on to ensure you are not vulnerable.

Amos Jeffries, release manager of the Squid-3 series, reports:
Vulnerable versions are 3.5.0.1 to 3.5.8 (inclusive), which are built with OpenSSL and configured for "SSL-Bump" decryption.
Integer overflows can lead to invalid pointer math reading from random memory on some CPU architectures. In the best case this leads to wrong TLS extensions being used for the client, worst-case a crash of the proxy terminating all active transactions.
Incorrect message size checks and assumptions about the existence of TLS extensions in the SSL/TLS handshake message can lead to very high CPU consumption (up to and including 'infinite loop' behaviour).
The above can be triggered remotely. Though there is one layer of authorization applied before this processing to check that the client is allowed to use the proxy, that check is generally weak. MS Skype on Windows XP is known to trigger some of these.
The FreeBSD port does not use SSL by default and is not vulnerable in the default configuration.
Dianne Skoll reports:
BUG FIX: Fix a buffer overflow found by Alexander Keller.
The bug can be manifested by an extended DUMP command using a system variable (that is a special variable whose name begins with '$')
Luke Farone reports:

Bugzilla Security Advisory
Login names (usually an email address) longer than 127 characters are silently truncated in MySQL which could cause the domain name of the email address to be corrupted. An attacker could use this vulnerability to create an account with an email address different from the one originally requested. The login name could then be automatically added to groups based on the group's regular expression setting.

The Mozilla Project reports:
Security researcher regenrecht reported via TippingPoint's Zero Day Initiative the possibility of memory corruption during the decoding of Ogg Vorbis files. This can cause a crash during decoding and has the potential for remote code execution.
The RedHat Project reports:
Will Drewry of the Google Security Team reported multiple issues in OGG Vorbis and Tremor libraries, that could cause application using those libraries to crash (NULL pointer dereference or divide by zero), enter an infinite loop or cause heap overflow caused by integer overflow.
Guanxing Wen reports:
PCRE library is prone to a vulnerability which leads to Heap Overflow. During the compilation of a malformed regular expression, more data is written on the malloced block than the expected size output by compile_regex(). The Heap Overflow vulnerability is caused by the following regular expression.
/(?J:(?|(:(?|(?'R')(\z(?|(?'R')(\k'R')|((?'R')))k'R')|((?'R')))H'Ak'Rf)|s(?'R')))/
A dry run of this particular regular expression with pcretest will reports "double free or corruption (!prev)". But it is actually a heap overflow problem. The overflow only affects pcre 8.x branch, pcre2 branch is not affected.
Drupal development team reports:
This security advisory fixes multiple vulnerabilities. See below for a list.
Cross-site Scripting - Ajax system - Drupal 7
A vulnerability was found that allows a malicious user to perform a cross-site scripting attack by invoking Drupal.ajax() on a whitelisted HTML element.
This vulnerability is mitigated on sites that do not allow untrusted users to enter HTML.
Cross-site Scripting - Autocomplete system - Drupal 6 and 7
A cross-site scripting vulnerability was found in the autocomplete functionality of forms. The requested URL is not sufficiently sanitized.
This vulnerability is mitigated by the fact that the malicious user must be allowed to upload files.
SQL Injection - Database API - Drupal 7
A vulnerability was found in the SQL comment filtering system which could allow a user with elevated permissions to inject malicious code in SQL comments.
This vulnerability is mitigated by the fact that only one contributed module that the security team found uses the comment filtering system in a way that would trigger the vulnerability. That module requires you to have a very high level of access in order to perform the attack.
Cross-site Request Forgery - Form API - Drupal 6 and 7
A vulnerability was discovered in Drupal's form API that could allow file upload value callbacks to run with untrusted input, due to form token validation not being performed early enough. This vulnerability could allow a malicious user to upload files to the site under another user's account.
This vulnerability is mitigated by the fact that the uploaded files would be temporary, and Drupal normally deletes temporary files automatically after 6 hours.
Information Disclosure in Menu Links - Access system - Drupal 6 and 7
Users without the "access content" permission can see the titles of nodes that they do not have access to, if the nodes are added to a menu on the site that the users have access to.
OpenSSH 6.8 and 6.9 incorrectly set TTYs to be world-writable. Local attackers may be able to write arbitrary messages to logged-in users, including terminal escape sequences. Reported by Nikolay Edigaryev.
Fixed a privilege separation weakness related to PAM support. Attackers who could successfully compromise the pre-authentication process for remote code execution and who had valid credentials on the host could impersonate other users.
Fixed a use-after-free bug related to PAM support that was reachable by attackers who could compromise the pre-authentication process for remote code execution.
OpenSSH 7.0 contained a logic error in PermitRootLogin= prohibit-password/without-password that could, depending on compile-time configuration, permit password authentication to root while preventing other forms of authentication. This problem was reported by Mantas Mikulenas.
Colin Percival reports:
1. SECURITY FIX: When constructing paths of objects being archived, a buffer could overflow by one byte upon encountering 1024, 2048, 4096, etc. byte paths. Theoretically this could be exploited by an unprivileged user whose files are being archived; I do not believe it is exploitable in practice, but I am offering a $1000 bounty for the first person who can prove me wrong: http://www.daemonology.net/blog/2015-08-21-tarsnap-1000-exploit-bounty.html
2. SECURITY FIX: An attacker with a machine's write keys, or with read keys and control of the tarsnap service, could make tarsnap allocate a large amount of memory upon listing archives or reading an archive the attacker created; on 32-bit machines, tarsnap can be caused to crash under the aforementioned conditions.
oCERT reports:
The stable VLC version suffers from an arbitrary pointer dereference vulnerability.
The vulnerability affects the 3GP file format parser, insufficient restrictions on a writable buffer can be exploited to execute arbitrary code via the heap memory. A specific 3GP file can be crafted to trigger the vulnerability.
Credit: vulnerability reported by Loren Maggiore of Trail of Bits.
Pengsu Cheng reports:
An use-after-free issue in Decoder.cpp was reported to upstream. The problem is due to lack of validation of ColorTableSize.
Gustavo Grieco reports:
We found a heap overflow and a DoS in the gdk-pixbuf implementation triggered by the scaling of a malformed bmp.
Tim Graham reports:
Denial-of-service possibility in logout() view by filling session store
Previously, a session could be created when anonymously accessing the django.contrib.auth.views.logout view (provided it wasn't decorated with django.contrib.auth.decorators.login_required as done in the admin). This could allow an attacker to easily create many new session records by sending repeated requests, potentially filling up the session store or causing other users' session records to be evicted.
The django.contrib.sessions.middleware.SessionMiddleware has been modified to no longer create empty session records.
This portion of the fix has been assigned CVE-2015-5963.
Additionally, on the 1.4 and 1.7 series only, the contrib.sessions.backends.base.SessionBase.flush() and cache_db.SessionStore.flush() methods have been modified to avoid creating a new empty session. Maintainers of third-party session backends should check if the same vulnerability is present in their backend and correct it if so.
This portion of the fix has been assigned CVE-2015-5964. Anyone reporting a similar vulnerability in a third-party session backend should not use this CVE ID.
Thanks Lin Hua Cheng for reporting the issue.
Unreal reports:
Summary: If SASL support is enabled in UnrealIRCd (this is not the default) and is also enabled in your services package then a malicious user with a services account can cause UnrealIRCd to crash.
Martin Prpic reports:
A double free flaw was found in the way JasPer's jasper_image_stop_load() function parsed certain JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash.
Feist Josselin reports:
A new use-after-free was found in Jasper JPEG-200. The use-after-free appears in the function mif_process_cmpt of the src/libjasper/mif/mif_cod.c file.
Stefan Cornelius reports:
There's an integer overflow in the allocate_cells() function when trying to allocate the memory for worksheet with specially crafted row/column dimensions. This can be exploited to cause a heap memory corruption. The most likely outcome of this is a crash when trying to initialize the cells later in the function.
Jodie Cunningham reports:
#1: A flaw was found in the way FreeXL reads sectors from the input file. A specially crafted file could possibly result in stack corruption near freexl.c:3752.
#2: A flaw was found in the function allocate_cells(). A specially crafted file with invalid workbook dimensions could possibly result in stack corruption near freexl.c:1074
#3: A flaw was found in the way FreeXL handles a premature EOF. A specially crafted input file could possibly result in stack corruption near freexl.c:1131
#4: FreeXL 1.0.0g did not properly check requests for workbook memory allocation. A specially crafted input file could cause a Denial of Service, or possibly write onto the stack.
NIST reports:
Apache Tomcat Connectors (mod_jk) before 1.2.41 ignores JkUnmount rules for subtrees of previous JkMount rules, which allows remote attackers to access otherwise restricted artifacts via unspecified vectors.
The Xen Project reports:
The QEMU model of the RTL8139 network card did not sufficiently validate inputs in the C+ mode offload emulation. This results in uninitialized memory from the QEMU process's heap being leaked to the domain as well as to the network.
A guest may be able to read sensitive host-level data relating to itself which resides in the QEMU process.
Such information may include things such as information relating to real devices backing emulated devices or passwords which the host administrator does not intend to share with the guest admin.
The Xen Project reports:
When unplugging an emulated block device the device was not fully unplugged, meaning a second unplug attempt would attempt to unplug the device a second time using a previously freed pointer.
An HVM guest which has access to an emulated IDE disk device may be able to exploit this vulnerability in order to take over the qemu process elevating its privilege to that of the qemu process.
The PHP project reports:

MediaWiki reports:
Internal review discovered that Special:DeletedContributions did not properly protect the IP of autoblocked users. This fix makes the functionality of Special:DeletedContributions consistent with Special:Contributions and Special:BlockList.
Internal review discovered that watchlist anti-csrf tokens were not being compared in constant time, which could allow various timing attacks. This could allow an attacker to modify a user's watchlist via csrf
John Menerick reported that MediaWiki's thumb.php failed to sanitize various error messages, resulting in xss.
Jouni Malinen reports:
The EAP-PWD module performed insufficient validation on packets received from an EAP peer. This module is not enabled in the default configuration. Administrators must manually enable it for their server to be vulnerable. Only versions 3.0 up to 3.0.8 are affected.
gnutls.org reports:
Kurt Roeckx reported that decoding a specific certificate with very long DistinguishedName (DN) entries leads to double free, which may result to a denial of service. Since the DN decoding occurs in almost all applications using certificates it is recommended to upgrade the latest GnuTLS version fixing the issue. Recommendation: Upgrade to GnuTLS 3.4.4, or 3.3.17.
Karthikeyan Bhargavan reports:
GnuTLS does not by default support MD5 signatures. Indeed the RSA-MD5 signature-hash algorithm needs to be explicitly enabled using the priority option VERIFY_ALLOW_SIGN_RSA_MD5. In the NORMAL and SECURE profiles, GnuTLS clients do not offer RSA-MD5 in the signature algorithms extension. However, we find that all GnuTLS clients still accept RSA-MD5 in the ServerKeyExchange and GnuTLS servers still accept RSA-MD5 in the ClientCertificateVerify.
oss-security-list@demlak.de reports:
An unauthenticated remote attacker is able to get the database password via webaccess due to wrong file permissions of the /logs/ folder in froxlor version 0.9.33.1 and earlier. The plain SQL password and username may be stored in the /logs/sql-error.log file. This directory is publicly reachable under the default configuration/setup.
Note that froxlor 0.9.33.2 prevents future logging of passwords but does not retroactively remove passwords already logged. Michael Kaufmann, the Froxlor lead developer reports:
Removing all .log files from the directory should do the job, alternatively just use the class.ConfigIO.php from Github
Best Practical reports:
RT 4.0.0 and above are vulnerable to a cross-site scripting (XSS) attack via the user and group rights management pages. This vulnerability is assigned CVE-2015-5475. It was discovered and reported by Marcin Kopec at Data Reliance Shared Service Center.
RT 4.2.0 and above are vulnerable to a cross-site scripting (XSS) attack via the cryptography interface. This vulnerability could allow an attacker with a carefully-crafted key to inject JavaScript into RT's user interface. Installations which use neither GnuPG nor S/MIME are unaffected.
Brian Warner reports:
The "flappserver" feature was found to have a vulnerability in the service-lookup code which, when combined with an attacker who has the ability to write files to a location where the flappserver process could read them, would allow that attacker to obtain control of the flappserver process.
The Mozilla Project reports:

Shibboleth consortium reports:
Shibboleth SP software crashes on well-formed but invalid XML.
The Service Provider software contains a code path with an uncaught exception that can be triggered by an unauthenticated attacker by supplying well-formed but schema-invalid XML in the form of SAML metadata or SAML protocol messages. The result is a crash and so causes a denial of service.
You must rebuild opensaml and shibboleth with xmltooling-1.5.5 or later. The easiest way to do so is to update the whole chain including shibboleth-2.5.5 an opensaml2.5.5.

Venustech ADLAB reports:
PCRE library is prone to a vulnerability which leads to Heap Overflow. During subpattern calculation of a malformed regular expression, an offset that is used as an array index is fully controlled and can be large enough so that unexpected heap memory regions are accessed.
One could at least exploit this issue to read objects nearby of the affected application's memory.
Such information disclosure may also be used to bypass memory protection method such as ASLR.

Description
When an application has Groovy on the classpath and that it uses standard Java serialization mechanism to communicate between servers, or to store local data, it is possible for an attacker to bake a special serialized object that will execute code directly when deserialized. All applications which rely on serialization and do not isolate the code which deserializes objects are subject to this vulnerability.

oCERT reports:
The FreeRADIUS server relies on OpenSSL to perform certificate validation, including Certificate Revocation List (CRL) checks. The FreeRADIUS usage of OpenSSL, in CRL application, limits the checks to leaf certificates, therefore not detecting revocation of intermediate CA certificates.
An unexpired client certificate, issued by an intermediate CA with a revoked certificate, is therefore accepted by FreeRADIUS.
Specifically sets the X509_V_FLAG_CRL_CHECK flag for leaf certificate CRL checks, but does not use X509_V_FLAG_CRL_CHECK_ALL for CRL checks on the complete trust chain.
The FreeRADIUS project advises that the recommended configuration is to use self-signed CAs for all EAP-TLS methods.
The Xen Project reports:
The xl command line utility mishandles long configuration values when passed as command line arguments, with a buffer overrun.
A semi-trusted guest administrator or controller, who is intended to be able to partially control the configuration settings for a domain, can escalate their privileges to that of the whole host.
The Xen Project reports:
A buggy loop in Xen's compat_iret() function iterates the wrong way around a 32-bit index. Any 32-bit PV guest kernel can trigger this vulnerability by attempting a hypercall_iret with EFLAGS.VM set.
Given the use of __get/put_user(), and that the virtual addresses in question are contained within the lower canonical half, the guest cannot clobber any hypervisor data. Instead, Xen will take up to 2^33 pagefaults, in sequence, effectively hanging the host.
Malicious guest administrators can cause a denial of service affecting the whole system.
The Xen Project reports:
With the introduction of version 2 grant table operations, a version check became necessary for most grant table related hypercalls. The GNTTABOP_swap_grant_ref call was lacking such a check. As a result, the subsequent code behaved as if version 2 was in use, when a guest issued this hypercall without a prior GNTTABOP_setup_table or GNTTABOP_set_version.
The effect is a possible NULL pointer dereferences. However, this cannot be exploited to elevate privileges of the attacking domain, as the maximum memory address that can be wrongly accessed this way is bounded to far below the start of hypervisor memory.
Malicious or buggy guest domain kernels can mount a denial of service attack which, if successful, can affect the whole system.
The Xen Project reports:
The handler for XEN_DOMCTL_gettscinfo failed to initialize a padding field subsequently copied to guest memory.
A similar leak existed in XEN_SYSCTL_getdomaininfolist, which is being addressed here regardless of that operation being declared unsafe for disaggregation by XSA-77.
Malicious or buggy stub domain kernels or tool stacks otherwise living outside of Domain0 may be able to read sensitive data relating to the hypervisor or other guests not under the control of that domain.
The Xen Project reports:
Qemu allows guests to not only read, but also write all parts of the PCI config space (but not extended config space) of passed through PCI devices not explicitly dealt with for (partial) emulation purposes.
Since the effect depends on the specific purpose of the the config space field, it's not possible to give a general statement about the exact impact on the host or other guests. Privilege escalation, host crash (Denial of Service), and leaked information all cannot be excluded.
The Xen Project reports:
Device model code dealing with guest PCI MSI-X interrupt management activities logs messages on certain (supposedly) invalid guest operations.
A buggy or malicious guest repeatedly invoking such operations may result in the host disk to fill up, possibly leading to a Denial of Service.
The Xen Project reports:
The mask bits optionally available in the PCI MSI capability structure are used by the hypervisor to occasionally suppress interrupt delivery. Unprivileged guests were, however, nevertheless allowed direct control of these bits.
Interrupts may be observed by Xen at unexpected times, which may lead to a host crash and therefore a Denial of Service.
The Xen Project reports:
Logic is in place to avoid writes to certain host config space fields when the guest must nevertheless be able to access their virtual counterparts. A bug in how this logic deals with accesses spanning multiple fields allows the guest to write to the host MSI message data field.
While generally the writes write back the values previously read, their value in config space may have got changed by the host between the qemu read and write. In such a case host side interrupt handling could become confused, possibly losing interrupts or allowing spurious interrupt injection into other guests.
Certain untrusted guest administrators may be able to confuse host side interrupt handling, leading to a Denial of Service.
The Xen Project reports:
XSA-77 put the majority of the domctl operations on a list excepting them from having security advisories issued for them if any effects their use might have could hamper security. Subsequently some of them got declared disaggregation safe, but for a small subset this was not really correct: Their (mis-)use may result in host lockups.
As a result, the potential security benefits of toolstack disaggregation are not always fully realised.
Domains deliberately given partial management control may be able to deny service to the entire host.
As a result, in a system designed to enhance security by radically disaggregating the management, the security may be reduced. But, the security will be no worse than a non-disaggregated design.
The Xen Project reports:
HVM guests are currently permitted to modify the memory and I/O decode bits in the PCI command register of devices passed through to them. Unless the device is an SR-IOV virtual function, after disabling one or both of these bits subsequent accesses to the MMIO or I/O port ranges would - on PCI Express devices - lead to Unsupported Request responses. The treatment of such errors is platform specific.
Furthermore (at least) devices under control of the Linux pciback driver in the host are handed to guests with the aforementioned bits turned off. This means that such accesses can similarly lead to Unsupported Request responses until these flags are set as needed by the guest.
In the event that the platform surfaces aforementioned UR responses as Non-Maskable Interrupts, and either the OS is configured to treat NMIs as fatal or (e.g. via ACPI's APEI) the platform tells the OS to treat these errors as fatal, the host would crash, leading to a Denial of Service.
The Xen Project reports:
The XEN_DOMCTL_memory_mapping hypercall allows long running operations without implementing preemption.
This hypercall is used by the device model as part of the emulation associated with configuration of PCI devices passed through to HVM guests and is therefore indirectly exposed to those guests.
This can cause a physical CPU to become busy for a significant period, leading to a host denial of service in some cases.
If a host denial of service is not triggered then it may instead be possible to deny service to the domain running the device model, e.g. domain 0.
This hypercall is also exposed more generally to all toolstacks. However the uses of it in libxl based toolstacks are not believed to open up any avenue of attack from an untrusted guest. Other toolstacks may be vulnerable however.
The vulnerability is exposed via HVM guests which have a PCI device assigned to them. A malicious HVM guest in such a configuration can mount a denial of service attack affecting the whole system via its associated device model (qemu-dm).
A guest is able to trigger this hypercall via operations which it is legitimately expected to perform, therefore running the device model as a stub domain does not offer protection against the host denial of service issue. However it does offer some protection against secondary issues such as denial of service against dom0.
The Xen Project reports:
Instructions with register operands ignore eventual segment overrides encoded for them. Due to an insufficiently conditional assignment such a bogus segment override can, however, corrupt a pointer used subsequently to store the result of the instruction.
A malicious guest might be able to read sensitive data relating to other guests, or to cause denial of service on the host. Arbitrary code execution, and therefore privilege escalation, cannot be excluded.
The Xen Project reports:
The code handling certain sub-operations of the HYPERVISOR_xen_version hypercall fails to fully initialize all fields of structures subsequently copied back to guest memory. Due to this hypervisor stack contents are copied into the destination of the operation, thus becoming visible to the guest.
A malicious guest might be able to read sensitive data relating to other guests.
The Xen Project reports:
Emulation routines in the hypervisor dealing with certain system devices check whether the access size by the guest is a supported one. When the access size is unsupported these routines failed to set the data to be returned to the guest for read accesses, so that hypervisor stack contents are copied into the destination of the operation, thus becoming visible to the guest.
A malicious HVM guest might be able to read sensitive data relating to other guests.
The Xen Project reports:
When instantiating an emulated VGA device for an x86 HVM guest qemu will by default enable a backend to expose that device, either SDL or VNC depending on the version of qemu and the build time configuration.
The libxl toolstack library does not explicitly disable these default backends when they are not enabled, leading to an unexpected backend running.
If either SDL or VNC is explicitly enabled in the guest configuration then only the expected backends will be enabled.
This affects qemu-xen and qemu-xen-traditional differently.
If qemu-xen was compiled with SDL support then this would result in an SDL window being opened if $DISPLAY is valid, or a failure to start the guest if not.
If qemu-xen was compiled without SDL support then qemu would instead start a VNC server listening on ::1 (IPv6 localhost) or 127.0.0.1 (IPv4 localhost) with IPv6 preferred if available. A VNC password will not be configured even if one is present in the guest configuration.
qemu-xen-traditional will never start a vnc backend unless explicitly configured. However by default it will start an SDL backend if it was built with SDL support and $DISPLAY is valid.
The Xen Project reports:
On ARM systems the code which deals with virtualizing the GIC distributor would, under various circumstances, log messages on a guest accessible code path without appropriate rate limiting.
A malicious guest could cause repeated logging to the hypervisor console, leading to a Denial of Service attack.
The Xen Project reports:
When decoding a guest write to a specific register in the virtual interrupt controller Xen would treat an invalid value as a critical error and crash the host.
By writing an invalid value to the GICD.SGIR register a guest can crash the host, resulting in a Denial of Service attack.

OpenSSL reports:
During certificate verification, OpenSSL (starting from version 1.0.1n and 1.0.2b) will attempt to find an alternative certificate chain if the first attempt to build such a chain fails. An error in the implementation of this logic can mean that an attacker could cause certain checks on untrusted certificates to be bypassed, such as the CA flag, enabling them to use a valid leaf certificate to act as a CA and "issue" an invalid certificate.

Squid security advisory 2015:2 reports:
Squid configured with cache_peer and operating on explicit proxy traffic does not correctly handle CONNECT method peer responses.
The bug is important because it allows remote clients to bypass security in an explicit gateway proxy.
However, the bug is exploitable only if you have configured cache_peer to receive CONNECT requests.
Squid security advisory 2015:1 reports:
Squid configured with client-first SSL-bump does not correctly validate X509 server certificate domain / hostname fields.
The bug is important because it allows remote servers to bypass client certificate validation. Some attackers may also be able to use valid certificates for one domain signed by a global Certificate Authority to abuse an unrelated domain.
However, the bug is exploitable only if you have configured Squid to perform SSL Bumping with the "client-first" or "bump" mode of operation.
Sites that do not use SSL-Bump are not vulnerable.
All Squid built without SSL support are not vulnerable to the problem.
The FreeBSD port does not use SSL by default and is not vulnerable in the default configuration.

Ignacio R. Morelle reports:
As mentioned in the Wesnoth 1.12.4 and Wesnoth 1.13.1 release announcements, a security vulnerability targeting add-on authors was found (bug #23504) which allowed a malicious user to obtain add-on server passphrases from the client's .pbl files and transmit them over the network, or store them in saved game files intended to be shared by the victim. This vulnerability affects all existing releases up to and including versions 1.12.2 and 1.13.0. Additionally, version 1.12.3 included only a partial fix that failed to guard users against attempts to read from .pbl files with an uppercase or mixed-case extension. CVE-2015-5069 and CVE-2015-5070 have been assigned to the vulnerability affecting .pbl files with a lowercase extension, and .pbl files with an uppercase or mixed-case extension, respectively.

Elastic reports:
Vulnerability Summary: All Elasticsearch versions from 1.0.0 to 1.5.2 are vulnerable to an attack that uses Elasticsearch to modify files read and executed by certain other applications.
Remediation Summary: Users should upgrade to 1.6.0. Alternately, ensure that other applications are not present on the system, or that Elasticsearch cannot write into areas where these applications would read.
Elastic reports:
Vulnerability Summary: All Elasticsearch versions prior to 1.5.2 and 1.4.5 are vulnerable to a directory traversal attack that allows an attacker to retrieve files from the server running Elasticsearch when one or more site plugins are installed, or when Windows is the server OS.
Remediation Summary: Users should upgrade to 1.4.5 or 1.5.2. Users that do not want to upgrade can address the vulnerability by disabling site plugins. See the CVE description for additional options.
Elastic reports:
Vulnerability Summary: Elasticsearch versions 1.3.0-1.3.7 and 1.4.0-1.4.2 have vulnerabilities in the Groovy scripting engine that were introduced in 1.3.0. The vulnerability allows an attacker to construct Groovy scripts that escape the sandbox and execute shell commands as the user running the Elasticsearch Java VM.
Remediation Summary: Users should upgrade to 1.3.8 or 1.4.3. Users that do not want to upgrade can address the vulnerability by setting script.groovy.sandbox.enabled to false in elasticsearch.yml and restarting the node.
Elastic reports:
Vulnerability Summary: Elasticsearch versions 1.3.x and prior have a default configuration for CORS that allows an attacker to craft links that could cause a user's browser to send requests to Elasticsearch instances on their local network. These requests could cause data loss or compromise.
Remediation Summary: Users should either set "http.cors.enabled" to false, or set "http.cors.allow-origin" to the value of the server that should be allowed access, such as localhost or a server hosting Kibana. Disabling CORS entirely with the former setting is more secure, but may not be suitable for all use cases.
Elastic reports:
Vulnerability Summary: In Elasticsearch versions 1.1.x and prior, dynamic scripting is enabled by default. This could allow an attacker to execute OS commands.
Remediation Summary: Disable dynamic scripting.
Logstash 1.4.2 was bundled with Elasticsearch 1.1.1, which is vulnerable to CVE-2014-3120. These binaries are used in Elasticsearch output specifically when using the node protocol. Since a node client joins the Elasticsearch cluster, the attackers could use scripts to execute commands on the host OS using the node client's URL endpoint. With 1.4.3 release, we are packaging Logstash with Elasticsearch 1.5.2 binaries which by default disables the ability to run scripts. This also affects users who are using the configuration option embedded=>true in the Elasticsearch output which starts a local embedded Elasticsearch cluster. This is typically used in development environment and proof of concept deployments. Regardless of this vulnerability, we strongly recommend not using embedded in production.
Note that users of transport and http protocol are not vulnerable to this attack.
Elastic reports:
An attacker could use the File output plugin with dynamic field references in the path option to traverse paths outside of Logstash directory. This technique could also be used to overwrite any files which can be accessed with permissions associated with Logstash user. This release sandboxes the paths which can be traversed using the configuration. We have also disallowed use of dynamic field references if the path options is pointing to an absolute path.
We have added this vulnerability to our CVE page and are working on filling out the CVE. We would like to thank Colin Coghill for reporting the issue and working with us on the resolution.
Elastic reports:
The vulnerability impacts deployments that use the either the zabbix or the nagios_nsca outputs. In these cases, an attacker with an ability to send crafted events to any source of data for Logstash could execute operating system commands with the permissions of the Logstash process.
Deployments that do not use the zabbix or the nagios_nsca outputs are not vulnerable and do not need to upgrade for this reason.
We have added this vulnerability to our CVE page and are working on filling out the CVE.
We would like to thank Jan Karwowski and Danila Borisiuk for reporting the issue and working with us on the resolution.
Elastic reports:
The combination of Logstash Forwarder and Lumberjack input (and output) was vulnerable to the POODLE attack in SSLv3 protocol.

Thanks to Tray Torrance, Marc Chadwick, and David Arena for reporting this.
SSLv3 is no longer supported; TLS 1.0+ is required (compatible with Logstash 1.4.2+).

Jon Yurek reports:
Thanks to MORI Shingo of DeNA Co., Ltd. for reporting this.
There is an issue where if an HTML file is uploaded with a .html extension, but the content type is listed as being `image/jpeg`, this will bypass a validation checking for images. But it will also pass the spoof check, because a file named .html and containing actual HTML passes the spoof check.
This change makes it so that we also check the supplied content type. So even if the file contains HTML and ends with .html, it doesn't match the content type of `image/jpeg` and so it fails.
chicken developer Peter Bex reports:
Using gcc's Address Sanitizer, it was discovered that the string-translate* procedure from the data-structures unit can scan beyond the input string's length up to the length of the source strings in the map that's passed to string-translate*. This issue was fixed in master 8a46020, and it will make its way into CHICKEN 4.10.
This bug is present in all released versions of CHICKEN.
chicken developer Moritz Heidkamp reports:
The substring-index[-ci] procedures of the data-structures unit are vulnerable to a buffer overrun attack when passed an integer greater than zero as the optional START argument.
As a work-around you can switch to SRFI 13's string-contains procedure which also returns the substring's index in case it is found.

Drupal development team reports:
Impersonation (OpenID module - Drupal 6 and 7 - Critical)
A vulnerability was found in the OpenID module that allows a malicious user to log in as other users on the site, including administrators, and hijack their accounts.
This vulnerability is mitigated by the fact that the victim must have an account with an associated OpenID identity from a particular set of OpenID providers (including, but not limited to, Verisign, LiveJournal, or StackExchange).
Open redirect (Field UI module - Drupal 7 - Less critical)
The Field UI module uses a "destinations" query string parameter in URLs to redirect users to new destinations after completing an action on a few administration pages. Under certain circumstances, malicious users can use this parameter to construct a URL that will trick users into being redirected to a 3rd party website, thereby exposing the users to potential social engineering attacks.
This vulnerability is mitigated by the fact that only sites with the Field UI module enabled are affected.
Drupal 6 core is not affected, but see the similar advisory for the Drupal 6 contributed CCK module: SA-CONTRIB-2015-126
Open redirect (Overlay module - Drupal 7 - Less critical)
The Overlay module displays administrative pages as a layer over the current page (using JavaScript), rather than replacing the page in the browser window. The Overlay module does not sufficiently validate URLs prior to displaying their contents, leading to an open redirect vulnerability.
This vulnerability is mitigated by the fact that it can only be used against site users who have the "Access the administrative overlay" permission, and that the Overlay module must be enabled.
Information disclosure (Render cache system - Drupal 7 - Less critical)
On sites utilizing Drupal 7's render cache system to cache content on the site by user role, private content viewed by user 1 may be included in the cache and exposed to non-privileged users.
This vulnerability is mitigated by the fact that render caching is not used in Drupal 7 core itself (it requires custom code or the contributed Render Cache module to enable) and that it only affects sites that have user 1 browsing the live site. Exposure is also limited if an administrative role has been assigned to the user 1 account (which is done, for example, by the Standard install profile that ships with Drupal core).
cURL reports:
libcurl can wrongly send HTTP credentials when re-using connections.
libcurl allows applications to set credentials for the upcoming transfer with HTTP Basic authentication, like with CURLOPT_USERPWD for example. Name and password. Just like all other libcurl options the credentials are sticky and are kept associated with the "handle" until something is made to change the situation.
Further, libcurl offers a curl_easy_reset() function that resets a handle back to its pristine state in terms of all settable options. A reset is of course also supposed to clear the credentials. A reset is typically used to clear up the handle and prepare it for a new, possibly unrelated, transfer.
Within such a handle, libcurl can also store a set of previous connections in case a second transfer is requested to a host name for which an existing connection is already kept alive.
With this flaw present, using the handle even after a reset would make libcurl accidentally use those credentials in a subsequent request if done to the same host name and connection as was previously accessed.
An example case would be first requesting a password protected resource from one section of a web site, and then do a second request of a public resource from a completely different part of the site without authentication. This flaw would then inadvertently leak the credentials in the second request.
libcurl can get tricked by a malicious SMB server to send off data it did not intend to.
In libcurl's state machine function handling the SMB protocol (smb_request_state()), two length and offset values are extracted from data that has arrived over the network, and those values are subsequently used to figure out what data range to send back.
The values are used and trusted without boundary checks and are just assumed to be valid. This allows carefully handcrafted packages to trick libcurl into responding and sending off data that was not intended. Or just crash if the values cause libcurl to access invalid memory.

Apache Software Foundation reports:
Low: Denial of Service CVE-2014-0230
When a response for a request with a request body is returned to the user agent before the request body is fully read, by default Tomcat swallows the remaining request body so that the next request on the connection may be processed. There was no limit to the size of request body that Tomcat would swallow. This permitted a limited Denial of Service as Tomcat would never close the connection and a processing thread would remain allocated to the connection.

StrongSwan Project reports
A denial-of-service and potential remote code execution vulnerability triggered by crafted IKE messages was discovered in strongSwan. Versions 5.2.2 and 5.3.0 are affected.
strongSwan Project reports:
An information leak vulnerability was fixed that, in certain IKEv2 setups, allowed rogue servers with a valid certificate accepted by the client to trick it into disclosing user credentials (even plain passwords if the client accepts EAP-GTC). This was caused because constraints against the server's authentication were enforced too late. All versions since 4.3.0 are affected.
Ben Murphy reports:
It is possible to break out of the Lua sandbox in Redis and execute arbitrary code.
This shouldn’t pose a threat to users under the trusted Redis security model where only trusted users can connect to the database. However, in real deployments there could be databases that can be accessed by untrusted users. The main deployments that are vulnerable are developers machines, places where redis servers can be reached via SSRF attacks and cloud hosting.

The Django project reports:
A change to session.flush() in the cached_db session backend in Django 1.8 mistakenly sets the session key to an empty string rather than None. An empty string is treated as a valid session key and the session cookie is set accordingly. Any users with an empty string in their session cookie will use the same session store. session.flush() is called by django.contrib.auth.logout() and, more seriously, by django.contrib.auth.login() when a user switches accounts. If a user is logged in and logs in again to a different account (without logging out) the session is flushed to avoid reuse. After the session is flushed (and its session key becomes '') the account details are set on the session and the session is saved. Any users with an empty string in their session cookie will now be logged into that account.
Thanks to Sam Cooke for reporting the issue.

MIT reports:
In MIT krb5 1.12 and later, when the KDC is configured with PKINIT support, an unauthenticated remote attacker can bypass the requires_preauth flag on a client principal and obtain a ciphertext encrypted in the principal's long-term key. This ciphertext could be used to conduct an off-line dictionary attack against the user's password.
cURL reports:
libcurl provides applications a way to set custom HTTP headers to be sent to the server by using CURLOPT_HTTPHEADER. A similar option is available for the curl command-line tool with the '--header' option.
When the connection passes through an HTTP proxy the same set of headers is sent to the proxy as well by default. While this is by design, it has not necessarily been clear nor understood by application programmers.
cURL reports:
libcurl keeps a pool of its last few connections around after use to facilitate easy, convenient, and completely transparent connection re-use for applications.
When doing HTTP requests NTLM authenticated, the entire connection becomes authenticated and not just the specific HTTP request which is otherwise how HTTP works. This makes NTLM special and a subject for special treatment in the code. With NTLM, once the connection is authenticated, no further authentication is necessary until the connection gets closed.
When doing HTTP requests Negotiate authenticated, the entire connection may become authenticated and not just the specific HTTP request which is otherwise how HTTP works, as Negotiate can basically use NTLM under the hood. curl was not adhering to this fact but would assume that such requests would also be authenticated per request.
libcurl supports HTTP "cookies" as documented in RFC 6265. Together with each individual cookie there are several different properties, but for this vulnerability we focus on the associated "path" element. It tells information about for which path on a given host the cookies is valid.
The internal libcurl function called sanitize_cookie_path() that cleans up the path element as given to it from a remote site or when read from a file, did not properly validate the input. If given a path that consisted of a single double-quote, libcurl would index a newly allocated memory area with index -1 and assign a zero to it, thus destroying heap memory it wasn't supposed to.
There is a private function in libcurl called fix_hostname() that removes a trailing dot from the host name if there is one. The function is called after the host name has been extracted from the URL libcurl has been told to act on.
If a URL is given with a zero-length host name, like in "http://:80" or just ":80", fix_hostname() will index the host name pointer with a -1 offset (as it blindly assumes a non-zero length) and both read and assign that address.
Jake Luciani reports:
Under its default configuration, Cassandra binds an unauthenticated JMX/RMI interface to all network interfaces. As RMI is an API for the transport and remote execution of serialized Java, anyone with access to this interface can execute arbitrary code as the running user.
Mitigation:
1.2.x has reached EOL, so users of <= 1.2.x are recommended to upgrade to a supported version of Cassandra, or manually configure encryption and authentication of JMX, (see https://wiki.apache.org/cassandra/JmxSecurity).
2.0.x users should upgrade to 2.0.14
2.1.x users should upgrade to 2.1.4
Alternately, users of any version not wishing to upgrade can reconfigure JMX/RMI to enable encryption and authentication according to https://wiki.apache.org/cassandra/JmxSecurityor http://docs.oracle.com/javase/7/docs/technotes/guides/management/agent.html

Colton Myers reports:
In order to fix potential shell injection vulnerabilities in salt modules, a change has been made to the various cmd module functions. These functions now default to python_shell=False, which means that the commands will not be sent to an actual shell.
The largest side effect of this change is that "shellisms", such as pipes, will not work by default. The modules shipped with salt have been audited to fix any issues that might have arisen from this change. Additionally, the cmd state module has been unaffected, and use of cmd.run in jinja is also unaffected. cmd.run calls on the CLI will also allow shellisms.
However, custom execution modules which use shellisms in cmd calls will break, unless you pass python_shell=True to these calls.
As a temporary workaround, you can set cmd_safe: False in your minion and master configs. This will revert the default, but is also less secure, as it will allow shell injection vulnerabilities to be written in custom code. We recommend you only set this setting for as long as it takes to resolve these issues in your custom code, then remove the override.

Jonathan Claudius reports:
RubyGems provides the ability of a domain to direct clients to a separate host that is used to fetch gems and make API calls against. This mechanism is implemented via DNS, specifically a SRV record _rubygems._tcp under the original requested domain.
RubyGems did not validate the hostname returned in the SRV record before sending requests to it. This left clients open to a DNS hijack attack, whereby an attacker could return a SRV of their choosing and get the client to use it.
Jason Geffner, CrowdStrike Senior Security Researcher reports:
VENOM, CVE-2015-3456, is a security vulnerability in the virtual floppy drive code used by many computer virtualization platforms. This vulnerability may allow an attacker to escape from the confines of an affected virtual machine (VM) guest and potentially obtain code-execution access to the host. Absent mitigation, this VM escape could open access to the host system and all other VMs running on that host, potentially giving adversaries significant elevated access to the host's local network and adjacent systems.

OISF Development Team reports:
The OISF development team is pleased to announce Suricata 2.0.8. This release fixes a number of issues in the 2.0 series.
The most important issue is a bug in the DER parser which is used to decode SSL/TLS certificates could crash Suricata. This issue was reported by Kostya Kortchinsky of the Google Security Team and was fixed by Pierre Chifflier of ANSSI.
Those processing large numbers of (untrusted) pcap files need to update as a malformed pcap could crash Suricata. Again, credits go to Kostya Kortchinsky.
Andreas Schneider reports:
libssh versions 0.5.1 and above have a logical error in the handling of a SSH_MSG_NEWKEYS and SSH_MSG_KEXDH_REPLY package. A detected error did not set the session into the error state correctly and further processed the packet which leads to a null pointer dereference. This is the packet after the initial key exchange and doesn’t require authentication.
This could be used for a Denial of Service (DoS) attack.
US-CERT/NIST reports:
The HWP filter in LibreOffice before 4.3.7 and 4.4.x before 4.4.2 and Apache OpenOffice before 4.1.2 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted HWP document, which triggers an out-of-bounds write.
Samuel Sidler reports:
The Genericons icon font package, which is used in a number of popular themes and plugins, contained an HTML file vulnerable to a cross-site scripting attack. All affected themes and plugins hosted on WordPress.org (including the Twenty Fifteen default theme) have been updated today by the WordPress security team to address this issue by removing this nonessential file. To help protect other Genericons usage, WordPress 4.2.2 proactively scans the wp-content directory for this HTML file and removes it. Reported by Robert Abela of Netsparker.
WordPress versions 4.2 and earlier are affected by a critical cross-site scripting vulnerability, which could enable anonymous users to compromise a site. WordPress 4.2.2 includes a comprehensive fix for this issue.
The release also includes hardening for a potential cross-site scripting vulnerability when using the visual editor. This issue was reported by Mahadev Subedi.

Jouni Malinen reports:
A vulnerability was found in how wpa_supplicant uses SSID information parsed from management frames that create or update P2P peer entries (e.g., Probe Response frame or number of P2P Public Action frames). SSID field has valid length range of 0-32 octets. However, it is transmitted in an element that has a 8-bit length field and potential maximum payload length of 255 octets. wpa_supplicant was not sufficiently verifying the payload length on one of the code paths using the SSID received from a peer device.
This can result in copying arbitrary data from an attacker to a fixed length buffer of 32 bytes (i.e., a possible overflow of up to 223 bytes). The SSID buffer is within struct p2p_device that is allocated from heap. The overflow can override couple of variables in the struct, including a pointer that gets freed. In addition about 150 bytes (the exact length depending on architecture) can be written beyond the end of the heap allocation.
This could result in corrupted state in heap, unexpected program behavior due to corrupted P2P peer device information, denial of service due to wpa_supplicant process crash, exposure of memory contents during GO Negotiation, and potentially arbitrary code execution.
Vulnerable versions/configurations
wpa_supplicant v1.0-v2.4 with CONFIG_P2P build option enabled (which is not compiled by default).
Attacker (or a system controlled by the attacker) needs to be within radio range of the vulnerable system to send a suitably constructed management frame that triggers a P2P peer device information to be created or updated.
The vulnerability is easiest to exploit while the device has started an active P2P operation (e.g., has ongoing P2P_FIND or P2P_LISTEN control interface command in progress). However, it may be possible, though significantly more difficult, to trigger this even without any active P2P operation in progress.

Richard J. Moore reports:
Due to two recent vulnerabilities identified in the built-in image format handling code, it was decided that this area required further testing to determine if further issues remained. Fuzzing using afl-fuzz located a number of issues in the handling of BMP, ICO and GIF files. The issues exposed included denial of service and buffer overflows leading to heap corruption. It is possible the latter could be used to perform remote code execution.
Ruby Developers report:
After reviewing RFC 6125 and RFC 5280, we found multiple violations of matching hostnames and particularly wildcard certificates.
Ruby’s OpenSSL extension will now provide a string-based matching algorithm which follows more strict behavior, as recommended by these RFCs. In particular, matching of more than one wildcard per subject/SAN is no-longer allowed. As well, comparison of these values are now case-insensitive.
Mark Sapiro reports:
A path traversal vulnerability has been discovered and fixed. This vulnerability is only exploitable by a local user on a Mailman server where the suggested Exim transport, the Postfix postfix_to_mailman.py transport or some other programmatic MTA delivery not using aliases is employed.
The Asterisk project reports:
When Asterisk registers to a SIP TLS device and and verifies the server, Asterisk will accept signed certificates that match a common name other than the one Asterisk is expecting if the signed certificate has a common name containing a null byte after the portion of the common name that Asterisk expected. For example, if Asterisk is trying to register to www.domain.com, Asterisk will accept certificates of the form www.domain.com\x00www.someotherdomain.com

Alan Coopersmith reports:
Ilja van Sprundel, a security researcher with IOActive, has discovered an issue in the parsing of BDF font files by libXfont. Additional testing by Alan Coopersmith and William Robinet with the American Fuzzy Lop (afl) tool uncovered two more issues in the parsing of BDF font files.
As libXfont is used by the X server to read font files, and an unprivileged user with access to the X server can tell the X server to read a given font file from a path of their choosing, these vulnerabilities have the potential to allow unprivileged users to run code with the privileges of the X server (often root access).

Best Practical reports:
RT 3.0.0 and above, if running on Perl 5.14.0 or higher, are vulnerable to a remote denial-of-service via the email gateway; any installation which accepts mail from untrusted sources is vulnerable, regardless of the permissions configuration inside RT. This denial-of-service may encompass both CPU and disk usage, depending on RT's logging configuration. This vulnerability is assigned CVE-2014-9472.
RT 3.8.8 and above are vulnerable to an information disclosure attack which may reveal RSS feeds URLs, and thus ticket data; this vulnerability is assigned CVE-2015-1165. RSS feed URLs can also be leveraged to perform session hijacking, allowing a user with the URL to log in as the user that created the feed; this vulnerability is assigned CVE-2015-1464.
The phpMyAdmin development team reports:
Risk of BREACH attack due to reflected parameter.
With a large number of crafted requests it was possible to infer the CSRF token by a BREACH attack.
Mitigation factor: this vulnerability can only be exploited in the presence of another vulnerability that allows the attacker to inject JavaScript into victim's browser.
The Mono project reports:
Mono’s implementation of the SSL/TLS stack failed to check the order of the handshake messages. Which would allow various attacks on the protocol to succeed. Details of this vulnerability are discussed in SKIP-TLS post.
Mono’s implementation of SSL/TLS also contained support for the weak EXPORT cyphers and was susceptible to the FREAK attack.
Simon Tatham reports:
When PuTTY has sensitive data in memory and has no further need for it, it should wipe the data out of its memory, in case malware later gains access to the PuTTY process or the memory is swapped out to disk or written into a crash dump file. An obvious example of this is the password typed during SSH login; other examples include obsolete session keys, public-key passphrases, and the private halves of public keys.
PuTTY 0.63 and earlier versions, after loading a private key from a disk file, mistakenly leak a memory buffer containing a copy of the private key, in the function ssh2_load_userkey. The companion function ssh2_save_userkey (only called by PuTTYgen) can also leak a copy, but only in the case where the file it tried to save to could not be created.

Peter Hutterer reports:
Olivier Fourdan from Red Hat has discovered a protocol handling issue in the way the X server code base handles the XkbSetGeometry request.
The issue stems from the server trusting the client to send valid string lengths in the request data. A malicious client with string lengths exceeding the request length can cause the server to copy adjacent memory data into the XKB structs. This data is then available to the client via the XkbGetGeometry request. The data length is at least up to 64k, it is possible to obtain more data by chaining strings, each string length is then determined by whatever happens to be in that 16-bit region of memory.
A similarly crafted request can likely cause the X server to crash.
Ryan Tandy reports:

PostgreSQL Project reports:
This update fixes multiple security issues reported in PostgreSQL over the past few months. All of these issues require prior authentication, and some require additional conditions, and as such are not considered generally urgent. However, users should examine the list of security holes patched below in case they are particularly vulnerable.
- CVE-2015-0241 Buffer overruns in "to_char" functions.
- CVE-2015-0242 Buffer overrun in replacement printf family of functions.
- CVE-2015-0243 Memory errors in functions in the pgcrypto extension.

- CVE-2014-8161 Constraint violation errors can cause display of values in columns which the user would not normally have rights to see.
SO-AND-SO reports:
CVE-2014-5352: In the MIT krb5 libgssapi_krb5 library, after gss_process_context_token() is used to process a valid context deletion token, the caller is left with a security context handle containing a dangling pointer. Further uses of this handle will result in use-after-free and double-free memory access violations. libgssrpc server applications such as kadmind are vulnerable as they can be instructed to call gss_process_context_token().
CVE-2014-9421: If the MIT krb5 kadmind daemon receives invalid XDR data from an authenticated user, it may perform use-after-free and double-free memory access violations while cleaning up the partial deserialization results. Other libgssrpc server applications may also be vulnerable if they contain insufficiently defensive XDR functions.
CVE-2014-9422: The MIT krb5 kadmind daemon incorrectly accepts authentications to two-component server principals whose first component is a left substring of "kadmin" or whose realm is a left prefix of the default realm.
CVE-2014-9423: libgssrpc applications including kadmind output four or eight bytes of uninitialized memory to the network as part of an unused "handle" field in replies to clients.
Ubuntu Security Notice USN-2489-1 reports:
Michal Zalewski discovered that unzip incorrectly handled certain malformed zip archives. If a user or automated system were tricked into processing a specially crafted zip archive, an attacker could possibly execute arbitrary code.
Debian reports:
web/acknowledge.c uses a string twice in a format string, but only allocates memory for one copy.
The RabbitMQ project reports:
Some user-controllable content was not properly HTML-escaped before being presented to a user in the management web UI:
- When a user unqueued a message from the management UI, message details (header names, arguments, etc.) were displayed unescaped. An attacker could publish a specially crafted message to add content or execute arbitrary Javascript code on behalf of a user, if this user unqueued the message from the management UI.
- When viewing policies, their name was displayed unescaped. An attacker could create a policy with a specially crafted name to add content or execute arbitrary Javascript code on behalf of a user who is viewing policies.
- When listing connected AMQP network clients, client details such as its version were displayed unescaped. An attacker could use a client with a specially crafted version field to add content or execute arbitrary Javascript code on behalf of a user who is viewing connected clients.
In all cases, the attacker needs a valid user account on the targeted RabbitMQ cluster.
Furthermore, some admin-controllable content was not properly escaped:
- user names;
- the cluster name.
Likewise, an attacker could add content or execute arbitrary Javascript code on behalf of a user using the management web UI. However, the attacker must be an administrator on the RabbitMQ cluster, thus a trusted user.

The Asterisk project reports:
CVE-2014-8150 reported an HTTP request injection vulnerability in libcURL. Asterisk uses libcURL in its func_curl.so module (the CURL() dialplan function), as well as its res_config_curl.so (cURL realtime backend) modules.
Since Asterisk may be configured to allow for user-supplied URLs to be passed to libcURL, it is possible that an attacker could use Asterisk as an attack vector to inject unauthorized HTTP requests if the version of libcURL installed on the Asterisk server is affected by CVE-2014-8150.
The Asterisk project reports:
Asterisk may be configured to only allow specific audio or video codecs to be used when communicating with a particular endpoint. When an endpoint sends an SDP offer that only lists codecs not allowed by Asterisk, the offer is rejected. However, in this case, RTP ports that are allocated in the process are not reclaimed.
This issue only affects the PJSIP channel driver in Asterisk. Users of the chan_sip channel driver are not affected.
As the resources are allocated after authentication, this issue only affects communications with authenticated endpoints.
Robert Krátký reports:
GHOST is a 'buffer overflow' bug affecting the gethostbyname() and gethostbyname2() function calls in the glibc library. This vulnerability allows a remote attacker that is able to make an application call to either of these functions to execute arbitrary code with the permissions of the user running the application. The gethostbyname() function calls are used for DNS resolving, which is a very common event. To exploit this vulnerability, an attacker must trigger a buffer overflow by supplying an invalid hostname argument to an application that performs a DNS resolution.
Adobe reports:
Successful exploitation could cause a crash and potentially allow an attacker to take control of the affected system. We are aware of reports that this vulnerability is being actively exploited in the wild via drive-by-download attacks against systems running Internet Explorer and Firefox on Windows 8.1 and below.

NVD reports:
Stack-based buffer overflow in utp.cpp in libutp, as used in Transmission before 2.74 and possibly other products, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted "micro transport protocol packets."
OpenSSL Security Advisory:
A memory leak can occur in the dtls1_buffer_record function under certain conditions. In particular this could occur if an attacker sent repeated DTLS records with the same sequence number but for the next epoch. The memory leak could be exploited by an attacker in a Denial of Service attack through memory exhaustion.
Adobe reports:
These updates address vulnerabilities that could potentially allow an attacker to take control of the affected system.

PolarSSL team reports:
During the parsing of a ASN.1 sequence, a pointer in the linked list of asn1_sequence is not initialized by asn1_get_sequence_of(). In case an error occurs during parsing of the list, a situation is created where the uninitialized pointer is passed to polarssl_free().
This sequence can be triggered when a PolarSSL entity is parsing a certificate. So practically this means clients when receiving a certificate from the server or servers in case they are actively asking for a client certificate.
oCERT reports:
The UnZip tool is an open source extraction utility for archives compressed in the zip format.
The unzip command line tool is affected by heap-based buffer overflows within the CRC32 verification, the test_compr_eb() and the getZip64Data() functions. The input errors may result in arbitrary code execution.
A specially crafted zip file, passed to unzip -t, can be used to trigger the vulnerability.
Samba team reports:
In Samba's AD DC we neglected to ensure that attempted modifications of the userAccountControl attribute did not allow the UF_SERVER_TRUST_ACCOUNT bit to be set.
Valentin Rusu reports:
Until KDE Applications 14.12.0, kwalletd incorrectly handled CBC encryption blocks when encrypting secrets in kwl files. The secrets were still encrypted, but the result binary data corresponded to an ECB encrypted block instead of CBC.
The ECB encryption algorithm, even if it'll scramble user data, will produce same encrypted byte sequence for the same input text. As a result, attackers may eventually find-out the encrypted text.

Debian Security Team reports:
Andrew Bartlett of Catalyst reported a defect affecting certain applications using the Libevent evbuffer API. This defect leaves applications which pass insanely large inputs to evbuffers open to a possible heap overflow or infinite loop. In order to exploit this flaw, an attacker needs to be able to find a way to provoke the program into trying to make a buffer chunk larger than what will fit into a single size_t or off_t.
cURL reports:
When libcurl sends a request to a server via a HTTP proxy, it copies the entire URL into the request and sends if off. If the given URL contains line feeds and carriage returns those will be sent along to the proxy too, which allows the program to for example send a separate HTTP request injected embedded in the URL. Many programs allow some kind of external sources to set the URL or provide partial pieces for the URL to ask for, and if the URL as received from the user is not stripped good enough this flaw allows malicious users to do additional requests in a way that was not intended, or just to insert request headers into the request that the program didn't intend. We are not aware of any exploit of this flaw.

MITRE reports:
wp-login.php in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 might allow remote attackers to reset passwords by leveraging access to an e-mail account that received a password-reset message.
wp-includes/http.php in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to conduct server-side request forgery (SSRF) attacks by referring to a 127.0.0.0/8 resource.
WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 might allow remote attackers to obtain access to an account idle since 2008 by leveraging an improper PHP dynamic type comparison for an MD5 hash.
Cross-site scripting (XSS) vulnerability in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to inject arbitrary web script or HTML via a crafted Cascading Style Sheets (CSS) token sequence in a post.
Cross-site scripting (XSS) vulnerability in Press This in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors
wp-includes/class-phpass.php in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to cause a denial of service (CPU consumption) via a long password that is improperly handled during hashing, a similar issue to CVE-2014-9016.
Cross-site request forgery (CSRF) vulnerability in wp-login.php in WordPress 3.7.4, 3.8.4, 3.9.2, and 4.0 allows remote attackers to hijack the authentication of arbitrary users for requests that reset passwords.
32-bit builds of PNG library are vulnerable to an unsigned integer overflow that is triggered by a crafted wide interlaced images. Overflow results in a heap corruption that will crash the application and may lead to the controlled overwrite of a selected portions of process address space.
RedHat reports:
Thomas Jarosch of Intra2net AG reported a number of denial of service issues (resource consumption) in the ELF parser used by file(1). These issues were fixed in the 5.21 release of file(1), but by mistake are missing from the changelog.
NVD reports:
The write_one_header function in mutt 1.5.23 does not properly handle newline characters at the beginning of a header, which allows remote attackers to cause a denial of service (crash) via a header with an empty body, which triggers a heap-based buffer overflow in the mutt_substrdup function.
CERT reports:
The Network Time Protocol (NTP) provides networked systems with a way to synchronize time for various services and applications. ntpd version 4.2.7 and previous versions allow attackers to overflow several buffers in a way that may allow malicious code to be executed. ntp-keygen prior to version 4.2.7p230 also uses a non-cryptographic random number generator when generating symmetric keys.
The buffer overflow vulnerabilities in ntpd may allow a remote unauthenticated attacker to execute arbitrary malicious code with the privilege level of the ntpd process. The weak default key and non-cryptographic random number generator in ntp-keygen may allow an attacker to gain information regarding the integrity checking and authentication encryption schemes.
The Git Project reports:
When using a case-insensitive filesystem an attacker can craft a malicious Git tree that will cause Git to overwrite its own .git/config file when cloning or checking out a repository, leading to arbitrary command execution in the client machine. If you are a hosting service whose users may fetch from your service to Windows or Mac OS X machines, you are strongly encouraged to update to protect such users who use existing versions of Git.
The OTRS project reports:
An attacker with valid OTRS credentials could access and manipulate ticket data of other users via the GenericInterface, if a ticket webservice is configured and not additionally secured.

Subversion's mod_dav_svn Apache HTTPD server module will crash when it receives a request for some invalid formatted special URIs.
We consider this to be a medium risk vulnerability. Repositories which allow for anonymous reads will be vulnerable without authentication. Unfortunately, no special configuration is required and all mod_dav_svn servers are vulnerable.
NVIDIA Unix security team reports:

Depending on how it is configured, the X server typically runs with raised privileges, and listens for GLX indirect rendering protocol requests from a local socket and potentially a TCP/IP port. The vulnerabilities could be exploited in a way that causes the X server to access uninitialized memory or overwrite arbitrary memory in the X server process. This can cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution.
ISC reports:
We have today posted updated versions of 9.9.6 and 9.10.1 to address a significant security vulnerability in DNS resolution. The flaw was discovered by Florian Maury of ANSSI, and applies to any recursive resolver that does not support a limit on the number of recursions. [CERTFR-2014-AVI-512], [USCERT VU#264212]
A flaw in delegation handling could be exploited to put named into an infinite loop, in which each lookup of a name server triggered additional lookups of more name servers. This has been addressed by placing limits on the number of levels of recursion named will allow (default 7), and on the number of queries that it will send before terminating a recursive query (default 50). The recursion depth limit is configured via the max-recursion-depth option, and the query limit via the max-recursion-queries option. For more information, see the security advisory at https://kb.isc.org/article/AA-01216/. [CVE-2014-8500] [RT #37580]
In addition, we have also corrected a potential security vulnerability in the GeoIP feature in the 9.10.1 release only. For more information on this issue, see the security advisory at https://kb.isc.org/article/AA-01217. [CVE-2014-8680]
The Asterisk project reports:
When handling a WebSocket frame the res_http_websocket module dynamically changes the size of the memory used to allow the provided payload to fit. If a payload length of zero was received the code would incorrectly attempt to resize to zero. This operation would succeed and end up freeing the memory but be treated as a failure. When the session was subsequently torn down this memory would get freed yet again causing a crash.
Users of the WebSocket functionality also did not take into account that provided text frames are not guaranteed to be NULL terminated. This has been fixed in chan_sip and chan_pjsip in the applicable versions.
Alan Coopersmith reports:
Ilja van Sprundel, a security researcher with IOActive, has discovered a large number of issues in the way the X server code base handles requests from X clients, and has worked with X.Org's security team to analyze, confirm, and fix these issues.
The vulnerabilities could be exploited to cause the X server to access uninitialized memory or overwrite arbitrary memory in the X server process. This can cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution.
The GLX extension to the X Window System allows an X client to send X protocol to the X server, to request that the X server perform OpenGL rendering on behalf of the X client. This is known as "GLX indirect rendering", as opposed to "GLX direct rendering" where the X client submits OpenGL rendering commands directly to the GPU, bypassing the X server and avoiding the X server code for GLX protocol handling.
Most GLX indirect rendering implementations share some common ancestry, dating back to "Sample Implementation" code from Silicon Graphics, Inc (SGI), which SGI originally commercially licensed to other Unix workstation and graphics vendors, and later released as open source, so those vulnerabilities may affect other licensees of SGI's code base beyond those running code from the X.Org Foundation or the XFree86 Project.
Unbound developer reports:
The resolver can be tricked into following an endless series of delegations, this consumes a lot of resources.
Werner LEMBERG reports:
The fix for CVE-2014-2240 was not 100% complete to fix the issue from the CVE completly.
The phpMyAdmin development team reports:
DoS vulnerability with long passwords.
With very long passwords it was possible to initiate a denial of service attack on phpMyAdmin.
We consider this vulnerability to be serious.
This vulnerability can be mitigated by configuring throttling in the webserver.
XSS vulnerability in redirection mechanism.
With a crafted URL it was possible to trigger an XSS in the redirection mechanism in phpMyAdmin.
We consider this vulnerability to be non critical.

In late November 2014 Dragana Damjanovic notified OpenVPN developers of a critical denial of service security vulnerability (CVE-2014-8104). The vulnerability allows an tls-authenticated client to crash the server by sending a too-short control channel packet to the server. In other words this vulnerability is denial of service only.
Erik de Castro Lopo reports:
Google Security Team member, Michele Spagnuolo, recently found two potential problems in the FLAC code base. They are:
- CVE-2014-9028: Heap buffer write overflow.
- CVE-2014-8962: Heap buffer read overflow.

The phpMyAdmin development team reports:
- With a crafted database, table or column name it is possible to trigger an XSS attack in the table browse page.
- With a crafted ENUM value it is possible to trigger XSS attacks in the table print view and zoom search pages.
- With a crafted value for font size it is possible to trigger an XSS attack in the home page.
These vulnerabilities can be triggered only by someone who is logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required pages. Moreover, exploitation of the XSS vulnerability related to the font size requires forgery of the pma_fontsize cookie.
In the GIS editor feature, a parameter specifying the geometry type was not correcly validated, opening the door to a local file inclusion attack.
This vulnerability can be triggered only by someone who is logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required page.
With a crafted file name it is possible to trigger an XSS in the error reporting page.
This vulnerability can be triggered only by someone who is logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required page.

Albert Aastals Cid reports:
kwebkitpart and the bookmarks:// io slave were not sanitizing input correctly allowing to some javascript being executed on the context of the referenced hostname.
Whilst in most cases, the JavaScript will be executed in an untrusted context, with the bookmarks IO slave, it will be executed in the context of the referenced hostname. It should however be noted that KDE mitigates this risk by attempting to ensure that such URLs cannot be embedded directly into Internet hosted content.
Yii PHP Framework developers report:
We are releasing Yii 1.1.15 to fix a security issue found in 1.1.14. We urge all 1.1.14 users to upgrade their Yii to this latest release. Note that the issue only affects 1.1.14. All previous releases are not affected. Upgrading to this release from 1.1.14 is very safe and will not break your existing code.
The vulnerability is in the CDetailView widget. When a Yii application uses this widget and configures the "value" property of a CDetailView attribute using end user inputs, it may allow attackers to potentially execute arbitrary PHP scripts on the server. We are not showing how to exploit it here to allow users to upgrade before details about the exploit become publicly known. To our knowledge the details of this issue are only known to core team members.

David Edmundson reports:
KDE workspace configuration module for setting the date and time has a helper program which runs as root for performing actions. This is secured with polkit.
This helper takes the name of the ntp utility to run as an argument. This allows a hacker to run any arbitrary command as root under the guise of updating the time.
An application can gain root priveledges from an admin user with either misleading information or no interaction.
On some systems the user will be shown a prompt to change the time. However, if the system has policykit-desktop-privileges installed, the datetime helper will be invoked by an admin user without any prompts.
Simon McVittie reports:
The patch issued by the D-Bus maintainers for CVE-2014-3636 was based on incorrect reasoning, and does not fully prevent the attack described as "CVE-2014-3636 part A", which is repeated below. Preventing that attack requires raising the system dbus-daemon's RLIMIT_NOFILE (ulimit -n) to a higher value. CVE-2014-7824 has been allocated for this vulnerability.
MITRE reports:
Absolute path traversal vulnerability in GNU Wget before 1.16, when recursion is enabled, allows remote FTP servers to write to arbitrary files, and consequently execute arbitrary code, via a LIST response that references the same filename within two entries, one of which indicates that the filename is for a symlink.
Konversation developers report:
Konversation's Blowfish ECB encryption support assumes incoming blocks to be the expected 12 bytes. The lack of a sanity-check for the actual size can cause a denial of service and an information leak to the local user.
TWiki developers report:
The debugenableplugins request parameter allows arbitrary Perl code execution.
Using an HTTP GET request towards a TWiki server, add a specially crafted debugenableplugins request parameter to TWiki's view script (typically port 80/TCP). Prior authentication may or may not be necessary.
A remote attacker can execute arbitrary Perl code to view and modify any file the webserver user has access to.
Example: http://www.example.com/do/view/Main/WebHome?debugenableplugins=BackupRestorePlugin%3bprint("Content-Type:text/html\r\n\r\nVulnerable!")%3bexit
The TWiki site is vulnerable if you see a page with text "Vulnerable!".
Kohsuke Kawaguchi from Jenkins team reports:
Historically, Jenkins master and slaves behaved as if they altogether form a single distributed process. This means a slave can ask a master to do just about anything within the confinement of the operating system, such as accessing files on the master or trigger other jobs on Jenkins.
This has increasingly become problematic, as larger enterprise deployments have developed more sophisticated trust separation model, where the administators of a master might take slaves owned by other teams. In such an environment, slaves are less trusted than the master. Yet the "single distributed process" assumption was not communicated well to the users, resulting in vulnerabilities in some deployments.
SECURITY-144 (CVE-2014-3665) introduces a new subsystem to address this problem. This feature is off by default for compatibility reasons. See Wiki for more details, who should turn this on, and implications.
CVE-2014-3566 is rated high. It only affects installations that accept slaves from less trusted computers, but this will allow an owner of of such slave to mount a remote code execution attack on Jenkins.
Aris Adamantiadis reports:
When accepting a new connection, the server forks and the child process handles the request. The RAND_bytes() function of openssl doesn't reset its state after the fork, but simply adds the current process id (getpid) to the PRNG state, which is not guaranteed to be unique.
The pidgin development team reports:
.
The phpMyAdmin development team reports:
With a crafted database or table name it is possible to trigger an XSS in SQL debug output when enabled and in server monitor page when viewing and analysing executed queries.
This vulnerability can be triggered only by someone who is logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required pages. Moreover, debugging SQL is a developer option which is disabled by default and expected to be disabled in production environments.
The Asterisk project reports:
The POODLE vulnerability is described under CVE-2014-3566. This advisory describes the Asterisk's project susceptibility to this vulnerability.
RedHat reports:
A denial of service flaw was found in libxml2, a library providing support to read, modify and write XML and HTML files. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, would lead to excessive CPU consumption (denial of service) based on excessive entity substitutions, even if entity substitution was disabled, which is the parser default behavior.
Drupal Security Team reports:
Drupal 7 includes a database abstraction API to ensure that queries executed against the database are sanitized to prevent SQL injection attacks. A vulnerability in this API allows an attacker to send specially crafted requests resulting in arbitrary SQL execution. Depending on the content of the requests this can lead to privilege escalation, arbitrary PHP execution, or other attacks. This vulnerability can be exploited by anonymous users.
The OpenSSL Project reports:
A flaw in the DTLS SRTP extension parsing code allows an attacker, who sends a carefully crafted handshake message, to cause OpenSSL to fail to free up to 64k of memory causing a memory leak. This could be exploited in a Denial Of Service attack. This issue affects OpenSSL 1.0.1 server implementations for both SSL/TLS and DTLS regardless of whether SRTP is used or configured. Implementations of OpenSSL that have been compiled with OPENSSL_NO_SRTP defined are not affected. [CVE-2014-3513].
When an OpenSSL SSL/TLS/DTLS server receives a session ticket the integrity of that ticket is first verified. In the event of a session ticket integrity check failing, OpenSSL will fail to free memory causing a memory leak. By sending a large number of invalid session tickets an attacker could exploit this issue in a Denial Of Service attack. [CVE-2014-3567].
OpenSSL has added support for TLS_FALLBACK_SCSV to allow applications to block the ability for a MITM attacker to force a protocol downgrade.
Some client applications (such as browsers) will reconnect using a downgraded protocol to work around interoperability bugs in older servers. This could be exploited by an active man-in-the-middle to downgrade connections to SSL 3.0 even if both sides of the connection support higher protocols. SSL 3.0 contains a number of weaknesses including POODLE [CVE-2014-3566].
When OpenSSL is configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake, and clients could be configured to send them. [CVE-2014-3568].

Bugzilla Security Advisory
Unauthorized Account Creation
An attacker creating a new Bugzilla account can override certain parameters when finalizing the account creation that can lead to the user being created with a different email address than originally requested. The overridden login name could be automatically added to groups based on the group's regular expression setting.
Cross-Site Scripting
During an audit of the Bugzilla code base, several places were found where cross-site scripting exploits could occur which could allow an attacker to access sensitive information.
Information Leak
If a new comment was marked private to the insider group, and a flag was set in the same transaction, the comment would be visible to flag recipients even if they were not in the insider group.
Social Engineering
Search results can be exported as a CSV file which can then be imported into external spreadsheet programs. Specially formatted field values can be interpreted as formulas which can be executed and used to attack a user's computer.
Best Practical reports:
RT 4.2.0 and above may be vulnerable to arbitrary execution of code by way of CVE-2014-7169, CVE-2014-7186, CVE-2014-7187, CVE-2014-6277, or CVE-2014-6271 -- collectively known as "Shellshock." This vulnerability requires a privileged user with access to an RT instance running with SMIME integration enabled; it applies to both mod_perl and fastcgi deployments. If you have already taken upgrades to bash to resolve "Shellshock," you are protected from this vulnerability in RT, and there is no need to apply this patch. This vulnerability has been assigned CVE-2014-7227.
Jenkins Security Advisory:
Please reference CVE/URL list for details
Note that this is different than the public "Shellshock" issue.
Specially crafted environment variables could lead to remote arbitrary code execution. This was fixed in bash 4.3.27, however the port was patched with a mitigation in 4.3.25_2.
The phpMyAdmin development team reports:
With a crafted ENUM value it is possible to trigger an XSS in table search and table structure pages. This vulnerability can be triggered only by someone who is logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required pages.
RedHat security team reports:
It was discovered that the fixed-sized redir_stack could be forced to overflow in the Bash parser, resulting in memory corruption, and possibly leading to arbitrary code execution when evaluating untrusted input that would not otherwise be run as code.
An off-by-one error was discovered in the way Bash was handling deeply nested flow control constructs. Depending on the layout of the .bss segment, this could allow arbitrary execution of code that would not otherwise be executed by Bash.
The rsyslog project reports:
potential abort when a message with PRI > 191 was processed if the "pri-text" property was used in active templates, this could be abused to a remote denial of service from permitted senders
The original fix for CVE-2014-3634 was not adequate.
Fish developer David Adam reports:
This release fixes a number of local privilege escalation vulnerability and one remote code execution vulnerability.
Adobe reports:
These updates address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system.
The Mozilla Project reports:
Antoine Delignat-Lavaud discovered that NSS is vulnerable to a variant of a signature forgery attack previously published by Daniel Bleichenbacher. This is due to lenient parsing of ASN.1 values involved in a signature and could lead to the forging of RSA certificates.
Martin Sandsmark reports:
krfb 4.14 [and earlier] embeds libvncserver which has had several security issues.
Several remotely exploitable security issues have been uncovered in libvncserver, some of which might allow a remote authenticated user code execution or application crashes.
Chet Ramey reports:
Under certain circumstances, bash will execute user code while processing the environment for exported function definitions.
The original fix released for CVE-2014-6271 was not adequate. A similar vulnerability was discovered and tagged as CVE-2014-7169.
The Asterisk project reports:
When an out of call message - delivered by either the SIP or PJSIP channel driver or the XMPP stack - is handled in Asterisk, a crash can occur if the channel servicing the message is sent into the ReceiveFax dialplan application while using the res_fax_spandsp module.
Note that this crash does not occur when using the res_fax_digium module. While this crash technically occurs due to a configuration issue, as attempting to receive a fax from a channel driver that only contains textual information will never succeed, the likelihood of having it occur is sufficiently high as to warrant this advisory.
The squid-cache project reports:
Due to incorrect buffer management Squid can be caused by an attacker to write outside its allocated SNMP buffer.
Simon McVittie reports:
Do not accept an extra fd in the padding of a cmsg message, which could lead to a 4-byte heap buffer overrun (CVE-2014-3635).
Reduce default for maximum Unix file descriptors passed per message from 1024 to 16, preventing a uid with the default maximum number of connections from exhausting the system bus' file descriptors under Linux's default rlimit (CVE-2014-3636).
Disconnect connections that still have a fd pending unmarshalling after a new configurable limit, pending_fd_timeout (defaulting to 150 seconds), removing the possibility of creating an abusive connection that cannot be disconnected by setting up a circular reference to a connection's file descriptor (CVE-2014-3637).
Reduce default for maximum pending replies per connection from 8192 to 128, mitigating an algorithmic complexity denial-of-service attack (CVE-2014-3638).
Reduce default for authentication timeout on the system bus from 30 seconds to 5 seconds, avoiding denial of service by using up all unauthenticated connection slots; and when all unauthenticated connection slots are used up, make new connection attempts block instead of disconnecting them (CVE-2014-3639).
The nginx project reports:
Security: it was possible to reuse SSL sessions in unrelated contexts if a shared SSL session cache or the same TLS session ticket key was used for multiple "server" blocks (CVE-2014-3616).

The phpMyAdmin development team reports:
Multiple XSS vulnerabilities in browse table, ENUM editor, monitor, query charts and table relations pages.
With a crafted database, table or a primary/unique key column name it is possible to trigger an XSS when dropping a row from the table. With a crafted column name it is possible to trigger an XSS in the ENUM editor dialog. With a crafted variable name or a crafted value for unit field it is possible to trigger a self-XSS when adding a new chart in the monitor page. With a crafted value for x-axis label it is possible to trigger a self-XSS in the query chart page. With a crafted relation name it is possible to trigger an XSS in table relations page.
XSS in view operations page.
With a crafted view name it is possible to trigger an XSS when dropping the view in view operation page.
serf Development list reports:
Serf provides APIs to retrieve information about a certificate. These APIs return the information as NUL terminated strings (commonly called C strings). X.509 uses counted length strings which may include a NUL byte. This means that a library user will interpret any information as ending upon seeing this NUL byte and will only see a partial value for that field.
Attackers could exploit this vulnerability to create a certificate that a client will accept for a different hostname than the full certificate is actually for by embedding a NUL byte in the certificate.
This can lead to a man-in-the-middle attack. There are no known instances of this problem being exploited in the wild and in practice it should be difficult to actually exploit this vulnerability.
Subversion Project reports:
Using the Serf RA layer of Subversion for HTTPS uses the apr_fnmatch API to handle matching wildcards in certificate Common Names and Subject Alternate Names. However, apr_fnmatch is not designed for this purpose. Instead it is designed to behave like common shell globbing. In particular this means that '*' is not limited to a single label within a hostname (i.e. it will match '.'). But even further apr_fnmatch supports '?' and character classes (neither of which are part of the RFCs defining how certificate validation works).
Subversion stores cached credentials by an MD5 hash based on the URL and the authentication realm of the server the credentials are cached for. MD5 has been shown to be subject to chosen plaintext hash collisions. This means it may be possible to generate an authentication realm which results in the same MD5 hash for a different URL.
The nginx project reports:
Security: pipelined commands were not discarded after STARTTLS command in SMTP proxy (CVE-2014-3556); the bug had appeared in 1.5.6.
The OpenSSL Project reports:
A flaw in OBJ_obj2txt may cause pretty printing functions such as X509_name_oneline, X509_name_print_ex et al. to leak some information from the stack. [CVE-2014-3508]
The issue affects OpenSSL clients and allows a malicious server to crash the client with a null pointer dereference (read) by specifying an SRP ciphersuite even though it was not properly negotiated with the client. [CVE-2014-5139]
If a multithreaded client connects to a malicious server using a resumed session and the server sends an ec point format extension it could write up to 255 bytes to freed memory. [CVE-2014-3509]
An attacker can force an error condition which causes openssl to crash whilst processing DTLS packets due to memory being freed twice. This can be exploited through a Denial of Service attack. [CVE-2014-3505]
An attacker can force openssl to consume large amounts of memory whilst processing DTLS handshake messages. This can be exploited through a Denial of Service attack. [CVE-2014-3506]
By sending carefully crafted DTLS packets an attacker could cause openssl to leak memory. This can be exploited through a Denial of Service attack. [CVE-2014-3507]
OpenSSL DTLS clients enabling anonymous (EC)DH ciphersuites are subject to a denial of service attack. A malicious server can crash the client with a null pointer dereference (read) by specifying an anonymous (EC)DH ciphersuite and sending carefully crafted handshake messages. [CVE-2014-3510]
A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate TLS 1.0 instead of higher protocol versions when the ClientHello message is badly fragmented. This allows a man-in-the-middle attacker to force a downgrade to TLS 1.0 even if both the server and the client support a higher protocol version, by modifying the client's TLS records. [CVE-2014-3511]
A malicious client or server can send invalid SRP parameters and overrun an internal buffer. Only applications which are explicitly set up for SRP use are affected. [CVE-2014-3512]
Albert Aastals Cid reports:
krfb embeds libvncserver which embeds liblzo2, it contains various flaws that result in integer overflow problems.
This potentially allows a malicious application to create a possible denial of service or code execution. Due to the need to exploit precise details of the target architecture and threading it is unlikely that remote code execution can be achieved in practice.
Samba developers report:
A malicious browser can send packets that may overwrite the heap of the target nmbd NetBIOS name services daemon. It may be possible to use this to generate a remote code execution vulnerability as the superuser (root).
Tomas Trnka reports:
Gpgme contains a buffer overflow in the gpgsm status handler that could possibly be exploited using a specially crafted certificate.
Martin Sandsmark reports:
The KAuth framework uses polkit-1 API which tries to authenticate using the requestors PID. This is prone to PID reuse race conditions.
This potentially allows a malicious application to pose as another for authentication purposes when executing privileged actions.
The Tor Project reports:
Tor before 0.2.4.23 and 0.2.5 before 0.2.5.6-alpha maintains a circuit after an inbound RELAY_EARLY cell is received by a client, which makes it easier for remote attackers to conduct traffic-confirmation attacks by using the pattern of RELAY and RELAY_EARLY cells as a means of communicating information about hidden service names.
The i2p project reports:
XSS and remote execution vulnerabilities reported by Exodus Intelligence.
Exodus Intelligence reports:
The vulnerability we have found is able to perform remote code execution with a specially crafted payload. This payload can be customized to unmask a user and show the public IP address in which the user connected from within 'a couple of seconds.'
Adobe does not properly restrict the SWF file format, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks against Bugzilla's JSONP endpoint, possibly obtaining sensitive bug information, via a crafted OBJECT element with SWF content satisfying the character-set requirements of a callback API.
Apache HTTP SERVER PROJECT reports:
mod_deflate: The DEFLATE input filter (inflates request bodies) now limits the length and compression ratio of inflated request bodies to avoid denial of service via highly compressed bodies. See directives DeflateInflateLimitRequestBody, DeflateInflateRatioLimit, and DeflateInflateRatioBurst.
mod_cgid: Fix a denial of service against CGI scripts that do not consume stdin that could lead to lingering HTTPD child processes filling up the scoreboard and eventually hanging the server. By default, the client I/O timeout (Timeout directive) now applies to communication with scripts. The CGIDScriptTimeout directive can be used to set a different timeout for communication with scripts.
Fix a race condition in scoreboard handling, which could lead to a heap buffer overflow.
core: HTTP trailers could be used to replace HTTP headers late during request processing, potentially undoing or otherwise confusing modules that examined or modified request headers earlier. Adds "MergeTrailers" directive to restore legacy behavior.
Tomcat Security Team reports:
Tomcat does not properly restrict XSLT stylesheets, which allows remote attackers to bypass security-manager restrictions and read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.
An integer overflow, when operated behind a reverse proxy, allows remote attackers to conduct HTTP request smuggling attacks via a crafted Content-Length HTTP header.
An integer overflow in parseChunkHeader allows remote attackers to cause a denial of service (resource consumption) via a malformed chunk size in chunked transfer coding of a request during the streaming of data.

Melissa Stone reports:
The MCollective aes_security public key plugin does not correctly validate certs against the CA. By exploiting this vulnerability within a race/initialization window, an attacker with local access could initiate an unauthorized MCollective client connection with a server, and thus control the mcollective plugins running on that server. This vulnerability requires a collective be configured to use the aes_security plugin. Puppet Enterprise and open source MCollective are not configured to use the plugin and are not vulnerable by default.
Richard J. Moore reports:
The builtin GIF decoder in QtGui prior to Qt 5.3 contained a bug that would lead to a null pointer dereference when loading certain hand crafted corrupt GIF files. This in turn would cause the application loading these hand crafted GIFs to crash.

Richard J. Moore reports:
The POP3 kioslave used by KMail will accept invalid certificates without presenting a dialog to the user due a bug that leads to an inability to display the dialog combined with an error in the way the result is checked.
This flaw allows an active attacker to perform MITM attacks against the ioslave which could result in the leakage of sensitive data such as the authentication details and the contents of emails.
Thijs Kinkhorst reports:
Postfixadmin has an SQL injection vulnerability. This vulnerability is only exploitable by authenticated users able to create new aliases.
Simon McVittie reports:
Alban Crequy at Collabora Ltd. discovered a bug in dbus-daemon's support for file descriptor passing. A malicious process could force system services or user applications to be disconnected from the D-Bus system bus by sending them a message containing a file descriptor, then causing that file descriptor to exceed the kernel's maximum recursion depth (itself introduced to fix a DoS) before dbus-daemon forwards the message to the victim process. Most services and applications exit when disconnected from the system bus, leading to a denial of service.
Additionally, Alban discovered that bug fd.o#79694, a bug previously reported by Alejandro Martínez Suárez which was n believed to be security flaw, could be used for a similar denial of service, by causing dbus-daemon to attempt to forward invalid file descriptors to a victim process when file descriptors become associated with the wrong message.

Michael Niedermayer and Luca Barbato report in upstream ffmpeg:
avutil/lzo: Fix integer overflow
Markus Franz Xaver Johannes Oberhumer reports, in the package's NEWS file:
Fixed a potential integer overflow condition in the "safe" decompressor variants which could result in a possible buffer overrun when processing maliciously crafted compressed input data.
As this issue only affects 32-bit systems and also can only happen if you use uncommonly huge buffer sizes where you have to decompress more than 16 MiB (2^24 bytes) compressed bytes within a single function call, the practical implications are limited.
Werner Koch reports:
This release includes a *security fix* to stop a possible DoS using garbled compressed data packets which can be used to put gpg into an infinite loop.
The samba project reports:
A malformed packet can cause the nmbd server to loop the CPU and prevent any further NetBIOS name service.
Valid unicode path names stored on disk can cause smbd to crash if an authenticated client attempts to read them using a non-unicode request.
The phpMyAdmin development team reports:
Self-XSS due to unescaped HTML output in recent/favorite tables navigation.
When marking a crafted database or table name as favorite or having it in recent tables, it is possible to trigger an XSS.
This vulnerability can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required form.
Self-XSS due to unescaped HTML output in navigation items hiding feature.
When hiding or unhiding a crafted table name in the navigation, it is possible to trigger an XSS.
This vulnerability can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required form.
Erik Ekman of the iodine project reports:
The client could bypass the password check by continuing after getting error from the server and guessing the network parameters. The server would still accept the rest of the setup and also network traffic.
The Asterisk project reports:
Asterisk Manager User Unauthorized Shell Access. Manager users can execute arbitrary shell commands with the MixMonitor manager action. Asterisk does not require system class authorization for a manager user to use the MixMonitor action, so any manager user who is permitted to use manager commands can potentially execute shell commands as the user executing the Asterisk process.
Exhaustion of Allowed Concurrent HTTP Connections. Establishing a TCP or TLS connection to the configured HTTP or HTTPS port respectively in http.conf and then not sending or completing a HTTP request will tie up a HTTP session. By doing this repeatedly until the maximum number of open HTTP sessions is reached, legitimate requests are blocked.
Simon MvVittie reports:
Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service flaw in dbus-daemon, part of the reference implementation of D-Bus. Additionally, in highly unusual environments the same flaw could lead to a side channel between processes that should not be able to communicate.

Alan Coopersmith reports:
Ilja van Sprundel, a security researcher with IOActive, has discovered several issues in the way the libXfont library handles the responses it receives from xfs servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues.
Most of these issues stem from libXfont trusting the font server to send valid protocol data, and not verifying that the values will not overflow or cause other damage. This code is commonly called from the X server when an X Font Server is active in the font path, so may be running in a setuid-root process depending on the X server in use. Exploits of this path could be used by a local, authenticated user to attempt to raise privileges; or by a remote attacker who can control the font server to attempt to execute code with the privileges of the X server.
CVE MITRE reports:
parser.c in libxml2 before 2.9.0, as used in Google Chrome before 28.0.1500.71 and other products, allows remote attackers to cause a denial of service (out-of-bounds read) via a document that ends abruptly, related to the lack of certain checks for the XML_PARSER_EOF state.
Stefan Cornelius reports:
It was discovered that libxml2, a library providing support to read, modify and write XML files, incorrectly performs entity substitution in the doctype prolog, even if the application using libxml2 disabled any entity substitution. A remote attacker could provide a specially-crafted XML file that, when processed, would lead to the exhaustion of CPU and memory resources or file descriptors.
This issue was discovered by Daniel Berrange of Red Hat.
OpenBSD and David Ramos reports:
Applications that use SSL_MODE_RELEASE_BUFFERS, such as nginx/apache, are prone to a race condition which may allow a remote attacker to crash the current service.
Richard J. Moore reports:
QXmlSimpleReader in Qt versions prior to 5.2 supports expansion of internal entities in XML documents without placing restrictions to ensure the document does not cause excessive memory usage. If an application using this API processes untrusted data then the application may use unexpected amounts of memory if a malicious document is processed.
It is possible to construct XML documents using internal entities that consume large amounts of memory and other resources to process, this is known as the 'Billion Laughs' attack. Qt versions prior to 5.2 did not offer protection against this issue.
strongSwan developers report:
Remote attackers are able to bypass authentication by rekeying an IKE_SA during (1) initiation or (2) re-authentication, which triggers the IKE_SA state to be set to established.
Only installations that actively initiate or re-authenticate IKEv2 IKE_SAs are affected.

The Django project reports:
These releases address an unexpected code-execution issue, a caching issue which can expose CSRF tokens and a MySQL typecasting issue. While these issues present limited risk and may not affect all Django users, we encourage all users to evaluate their own risk and upgrade as soon as possible.
Applications that use SSL_MODE_RELEASE_BUFFERS, such as nginx, are prone to a race condition which may allow a remote attacker to inject random data into other connections.
The login form had no CSRF protection, meaning that an attacker could force the victim to log in using the attacker's credentials. If the victim then reports a new security sensitive bug, the attacker would get immediate access to this bug.
Due to changes involved in the Bugzilla API, this fix is not backported to the 4.0 and 4.2 branches, meaning that Bugzilla 4.0.12 and older, and 4.2.8 and older, will remain vulnerable to this issue.
Dangerous control characters can be inserted into Bugzilla, notably into bug comments. If the text, which may look safe, is copied into a terminal such as xterm or gnome-terminal, then unexpected commands could be executed on the local machine.
Jan Lieskovsky reports:
OpenLDAP does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority
cURL reports:
When doing GSSAPI authentication, libcurl unconditionally performs credential delegation. This hands the server a copy of the client's security credentials, allowing the server to impersonate the client to any other using the same GSSAPI mechanism.
Sebastian Krahmer reports:
A privilege escalation flaw was found in the way dbus-glib, the D-Bus add-on library to integrate the standard D-Bus library with the GLib thread abstraction and main loop, performed filtering of the message sender (message source subject), when the NameOwnerChanged signal was received. A local attacker could use this flaw to escalate their privileges.
Hamid Zamani reports:
multiple security problems (buffer overflows, format string vulnerabilities and missing input sanitising), which could lead to the execution of arbitrary code.
Debian reports:
Heap-based buffer overflow in msadpcm.c in libaudiofile in audiofile 0.2.6 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted WAV file.

OpenSSL reports:
A flaw in the implementation of Montgomery Ladder Approach would create a side-channel that leaks sensitive timing information.
A local attacker might be able to snoop a signing process and might recover the signing key from it.
The OpenAFS development team reports:
An attacker with the ability to connect to an OpenAFS fileserver can trigger a buffer overflow, crashing the server.
The buffer overflow can be triggered by sending an unauthenticated request for file server statistical information.
Clients are not affected.
OpenSSL Reports:
A missing bounds check in the handling of the TLS heartbeat extension can be used to reveal up to 64k of memory to a connected client or server.
Affected users should upgrade to OpenSSL 1.0.1g. Users unable to immediately upgrade can alternatively recompile OpenSSL with -DOPENSSL_NO_HEARTBEATS.
The bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop communications, steal data directly from the services and users and to impersonate services and users.
The code used to handle the Heartbeat Extension does not do sufficient boundary checks on record length, which allows reading beyond the actual payload.
The OTRS Project reports:
An attacker could embed OTRS in a hidden iframe tag of another page, tricking the user into clicking links in OTRS.
oCERT reports:
The LibYAML project is an open source YAML 1.1 parser and emitter written in C.
The library is affected by a heap-based buffer overflow which can lead to arbitrary code execution. The vulnerability is caused by lack of proper expansion for the string passed to the yaml_parser_scan_uri_escapes() function.
A specially crafted YAML file, with a long sequence of percent-encoded characters in a URL, can be used to trigger the overflow.
The Icinga Team reports:

Jan Kundrát reports:
An SSL stripping vulnerability was discovered in Trojitá, a fast Qt IMAP e-mail client. User's credentials are never leaked, but if a user tries to send an e-mail, the automatic saving into the "sent" or "draft" folders could happen over a plaintext connection even if the user's preferences specify STARTTLS as a requirement.
The nginx project reports:
A bug in the experimental SPDY implementation in nginx was found, which might allow an attacker to cause a heap memory buffer overflow in a worker process by using a specially crafted request, potentially resulting in arbitrary code execution (CVE-2014-0133).
The problem affects nginx 1.3.15 - 1.5.11, compiled with the ngx_http_spdy_module module (which is not compiled by default) and without --with-debug configure option, if the "spdy" option of the "listen" directive is used in a configuration file.
The problem is fixed in nginx 1.5.12, 1.4.7.

Samba project reports:
In Samba's SAMR server we neglect to ensure that attempted password changes will update the bad password count, nor set the lockout flags. This would allow a user unlimited attempts against the password by simply calling ChangePasswordUser2 repeatedly.
This is available without any other authentication.
smbcacls can remove a file or directory ACL by mistake.
The Asterisk project reports:
Stack Overflow in HTTP Processing of Cookie Headers. Sending a HTTP request that is handled by Asterisk with a large number of Cookie headers could overflow the stack. You could even exhaust memory if you sent an unlimited number of headers in the request.
Denial of Service Through File Descriptor Exhaustion with chan_sip Session-Timers. An attacker can use all available file descriptors using SIP INVITE requests. Asterisk will respond with code 400, 420, or 422 for INVITEs meeting this criteria. Each INVITE meeting these conditions will leak a channel and several file descriptors. The file descriptors cannot be released without restarting Asterisk which may allow intrusion detection systems to be bypassed by sending the requests slowly.
Remote Crash Vulnerability in PJSIP channel driver. A remotely exploitable crash vulnerability exists in the PJSIP channel driver if the "qualify_frequency" configuration option is enabled on an AOR and the remote SIP server challenges for authentication of the resulting OPTIONS request. The response handling code wrongly assumes that a PJSIP endpoint will always be associated with an outgoing request which is incorrect.
Mateusz Jurczyk reports:
Out of bounds stack-based read/write in cf2_hintmap_build.
This is a critical vulnerability in the CFF Rasterizer code recently contributed by Adobe, leading to potential arbitrary code execution in the context of the FreeType2 library client.
Secunia reports:
Secunia Research has discovered two vulnerabilities in XMMS, which can be exploited by malicious people to compromise a user's system.
1) An integer underflow error exists in the processing of skin bitmap images. This can be exploited to cause a stack-based buffer overflow via specially crafted skin images containing manipulated header information.
Successful exploitation allows execution of arbitrary code.
2) An integer overflow error exists in the processing of skin bitmap images. This can be exploited to cause memory corruption via specially crafted skin images containing manipulated header information.
Successful exploitation may allow the execution of arbitrary code.
The nginx project reports:
A bug in the experimental SPDY implementation in nginx 1.5.10 was found, which might allow an attacker to corrupt worker process memory by using a specially crafted request, potentially resulting in arbitrary code execution (CVE-2014-0088).
The problem only affects nginx 1.5.10 on 32-bit platforms, compiled with the ngx_http_spdy_module module (which is not compiled by default), if the "spdy" option of the "listen" directive is used in a configuration file.
GnuTLS project reports:
A vulnerability was discovered that affects the certificate verification functions of all gnutls versions. A specially crafted certificate could bypass certificate validation checks. The vulnerability was discovered during an audit of GnuTLS for Red Hat.
Suman Jana reported a vulnerability that affects the certificate verification functions of gnutls 2.11.5 and later versions. A version 1 intermediate certificate will be considered as a CA certificate by default (something that deviates from the documented behavior).
The Fine Free file project reports:
file before 5.17 allows context-dependent attackers to cause a denial of service (infinite recursion, CPU consumption, and crash) via a crafted indirect offset value in the magic of a file.
Vincent Danen via Red Hat Issue Tracker reports:
A vulnerability was reported in Python's socket module, due to a boundary error within the sock_recvfrom_into() function, which could be exploited to cause a buffer overflow. This could be used to crash a Python application that uses the socket.recvfrom_info() function or, possibly, execute arbitrary code with the permissions of the user running vulnerable Python code.
This vulnerable function, socket.recvfrom_into(), was introduced in Python 2.5. Earlier versions are not affected by this flaw.
Subversion Project reports:
Subversion's mod_dav_svn Apache HTTPD server module will crash when it receives an OPTIONS request against the server root and Subversion is configured to handle the server root and SVNListParentPath is on. This can lead to a DoS. There are no known instances of this problem being exploited in the wild, but the details of how to exploit it have been disclosed on the Subversion development mailing list.
The OTRS Project reports:
An attacker could send a specially prepared HTML email to OTRS. If he can then trick an agent into following a special link to display this email, JavaScript code would be executed.
PostgreSQL Project reports:
This update fixes CVE-2014-0060, in which PostgreSQL did not properly enforce the WITH ADMIN OPTION permission for ROLE management. Before this fix, any member of a ROLE was able to grant others access to the same ROLE regardless if the member was given the WITH ADMIN OPTION permission. It also fixes multiple privilege escalation issues, including: CVE-2014-0061, CVE-2014-0062, CVE-2014-0063, CVE-2014-0064, CVE-2014-0065, and CVE-2014-0066. More information on these issues can be found on our security page and the security issue detail wiki page.
With this release, we are also alerting users to a known security hole that allows other users on the same machine to gain access to an operating system account while it is doing "make check": CVE-2014-0067. "Make check" is normally part of building PostgreSQL from source code. As it is not possible to fix this issue without causing significant issues to our testing infrastructure, a patch will be released separately and publicly. Until then, users are strongly advised not to run "make check" on machines where untrusted users have accounts.

libyaml was prone to a heap overflow that could result in arbitrary code execution. Pkg uses libyaml to parse the package manifests in some cases. Pkg also used libyaml to parse the remote repository until 1.2.
RedHat Product Security Team reports on libyaml:
A heap-based buffer overflow flaw was found in the way libyaml parsed YAML tags. A remote attacker could provide a specially-crafted YAML document that, when parsed by an application using libyaml, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
Florian Weimer of the Red Hat Product Security Team reports:
Due to a missing check during assembly of the HTTP request line a long target server name in the PROXY-CONNECT address can cause a stack buffer overrun. Exploitation requires that the attacker is able to provide the target server name to the PROXY-CONNECT address in the command line. This can happen for example in scripts that receive data from untrusted sources.
The OTRS Project reports:
SQL injection issue
An attacker that managed to take over the session of a logged in customer could create tickets and/or send follow-ups to existing tickets due to missing challenge token checks.
The RT development team reports:
Versions of RT between 4.2.0 and 4.2.2 (inclusive) are vulnerable to a denial-of-service attack via the email gateway; any installation which accepts mail from untrusted sources is vulnerable, regardless of the permissions configuration inside RT. This vulnerability is assigned CVE-2014-1474.
This vulnerability is caused by poor parsing performance in the Email::Address::List module, which RT depends on. We recommend that affected users upgrade their version of Email::Address::List to v0.02 or above, which resolves the issue. Due to a communications mishap, the release on CPAN will temporarily appear as "unauthorized," and the command-line cpan client will hence not install it. We expect this to be resolved shortly; in the meantime, the release is also available from our server.
strongSwan Project reports:
A DoS vulnerability triggered by crafted IKEv1 fragmentation payloads was discovered in strongSwan's IKE daemon charon. All versions since 5.0.2 are affected.
A DoS vulnerability and potential authorization bypass triggered by a crafted ID_DER_ASN1_DN ID payload was discovered in strongSwan. All versions since 4.3.3 are affected.
A DoS vulnerability in strongSwan was discovered, which is triggered by XAuth usernames and EAP identities in versions 5.0.3 and 5.0.4.
Varnish Cache Project reports:
If Varnish receives a certain illegal request, and the subroutine 'vcl_error{}' restarts the request, the varnishd worker process will crash with an assert.
The varnishd management process will restart the worker process, but there will be a brief interruption of service and the cache will be emptied, causing more traffic to go to the backend.
We are releasing this advisory because restarting from vcl_error{} is both fairly common and documented.
This is purely a denial of service vulnerability, there is no risk of privilege escalation.
Workaround
Insert this at the top of your VCL file:
sub vcl_error { if (obj.status == 400 || obj.status == 413) { return(deliver); } } Or add this test at the top of your existing vcl_error{}.
Adobe reports:
These updates address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system.

Oracle reports:
Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox prior to 3.2.20, 4.0.22, 4.1.30, 4.2.22, and 4.3.6 allows local users to affect confidentiality, integrity, and availability via unknown vectors related to Core.
ntp.org reports:
Unrestricted access to the monlist feature in ntp_request.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service (traffic amplification) via forged (1) REQ_MON_GETLIST or (2) REQ_MON_GETLIST_1 requests, as exploited in the wild in December 2013
Use noquery to your default restrictions to block all status queries.
Use disable monitor to disable the ``ntpdc -c monlist'' command while still allowing other status queries.
Eric Stanley reports:
Most CGIs previously incremented the input variable counter twice when it encountered a long key value. This could cause the CGI to read past the end of the list of CGI variables.
ISC reports:
Because of a defect in handling queries for NSEC3-signed zones, BIND can crash with an "INSIST" failure in name.c when processing queries possessing certain properties. By exploiting this defect an attacker deliberately constructing a query with the right properties could achieve denial of service against an authoritative nameserver serving NSEC3-signed zones.
freedesktop.org reports:
A BDF font file containing a longer than expected string can cause a buffer overflow on the stack. Testing in X servers built with Stack Protector restulted in an immediate crash when reading a user-proveded specially crafted font.
As libXfont is used to read user-specified font files in all X servers distributed by X.Org, including the Xorg server which is often run with root privileges or as setuid-root in order to access hardware, this bug may lead to an unprivileged user acquiring root privileges in some systems.

- Fix for DTLS retransmission bug [CVE-2013-6450]
Revive reports:
An SQL-injection vulnerability was recently discovered and reported to the Revive Adserver team by Florian Sander. The vulnerability is known to be already exploited to gain unauthorised access to the application using brute force mechanisms, however other kind of attacks might be possible and/or already in use. The risk is rated to be critical as the most common end goal of the attackers is to spread malware to the visitors of all the websites and ad networks that the ad server is being used on.
The vulnerability is also present and exploitable in OpenX Source 2.8.11 and earlier versions, potentially back to phpAdsNew 2.0.x.
cURL project reports:
libcurl is vulnerable to a case of missing out the checking of the certificate CN or SAN name field when the digital signature verification is turned off.
libcurl offers two separate and independent options for verifying a server's TLS certificate. CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST. The first one tells libcurl to verify the trust chain using a CA cert bundle, while the second tells libcurl to make sure that the name fields in the server certificate meets the criteria. Both options are enabled by default.
This flaw had the effect that when an application disabled CURLOPT_SSL_VERIFYPEER, libcurl mistakenly also skipped the CURLOPT_SSL_VERIFYHOST check. Applications can disable CURLOPT_SSL_VERIFYPEER and still achieve security by doing the check on its own using other means.
The curl command line tool is not affected by this problem as it either enables both options or disables both at the same time.
Werner Koch reports:
CVE-2013-4576 has been assigned to this security bug.
The paper describes two attacks. The first attack allows to distinguish keys: An attacker is able to notice which key is currently used for decryption. This is in general not a problem but may be used to reveal the information that a message, encrypted to a commonly not used key, has been received by the targeted machine. We do not have a software solution to mitigate this attack.
The second attack is more serious. It is an adaptive chosen ciphertext attack to reveal the private key. A possible scenario is that the attacker places a sensor (for example a standard smartphone) in the vicinity of the targeted machine. That machine is assumed to do unattended RSA decryption of received mails, for example by using a mail client which speeds up browsing by opportunistically decrypting mails expected to be read soon. While listening to the acoustic emanations of the targeted machine, the smartphone will send new encrypted messages to that machine and re-construct the private key bit by bit. A 4096 bit RSA key used on a laptop can be revealed within an hour.
The Asterisk project reports:
A 16 bit SMS message that contains an odd message length value will cause the message decoding loop to run forever. The message buffer is not on the stack but will be overflowed resulting in corrupted memory and an immediate crash.
External control protocols, such as the Asterisk Manager Interface, often have the ability to get and set channel variables; this allows the execution of dialplan functions. Dialplan functions within Asterisk are incredibly powerful, which is wonderful for building applications using Asterisk. But during the read or write execution, certain diaplan functions do much more. For example, reading the SHELL() function can execute arbitrary commands on the system Asterisk is running on. Writing to the FILE() function can change any file that Asterisk has write access to. When these functions are executed from an external protocol, that execution could result in a privilege escalation.
The phpMyFAQ team reports:
Secunia noticed while analysing the advisory that authenticated users with "Right to add attachments" are able to exploit an already publicly known issue in the bundled Ajax File Manager of phpMyFAQ version 2.8.3, which leads to arbitrary PHP code execution for authenticated users with the permission "Right to add attachments".
Recurity Labs Team project reports:
Zabbix agent is vulnerable to remote command execution from the Zabbix server in some cases.
Stefan Esser reports:
The PHP function openssl_x509_parse() uses a helper function called asn1_time_to_time_t() to convert timestamps from ASN1 string format into integer timestamp values. The parser within this helper function is not binary safe and can therefore be tricked to write up to five NUL bytes outside of an allocated buffer.
This problem can be triggered by x509 certificates that contain NUL bytes in their notBefore and notAfter timestamp fields and leads to a memory corruption that might result in arbitrary code execution.
Depending on how openssl_x509_parse() is used within a PHP application the attack requires either a malicious cert signed by a compromised/malicious CA or can be carried out with a self-signed cert.

The OpenTTD Team reports:
The problem is caused by incorrectly handling the fact that the aircraft circling the corner airport will be outside of the bounds of the map. In the 'out of fuel' crash code the height of the tile under the aircraft is determined. In this case that means a tile outside of the allocated map array, which could occasionally trigger invalid reads.
Monitorix Project reports:
A serious bug in the built-in HTTP server. It was discovered that the handle_request() routine did not properly perform input sanitization which led into a number of security vulnerabilities. An unauthenticated, remote attacker could exploit this flaw to execute arbitrary commands on the remote host. All users still using older versions are advised to upgrade to this version, which resolves this issue.
Subversion Project reports:
mod_dontdothat does not restrict requests from serf based clients
mod_dontdothat allows you to block update REPORT requests against certain paths in the repository. It expects the paths in the REPORT request to be absolute URLs. Serf based clients send relative URLs instead of absolute URLs in many cases. As a result these clients are not blocked as configured by mod_dontdothat.
mod_dav_svn assertion triggered by non-canonical URLs in autoversioning commits
When SVNAutoversioning is enabled via SVNAutoversioning on commits can be made by single HTTP requests such as MKCOL and PUT. If Subversion is built with assertions enabled any such requests that have non-canonical URLs, such as URLs with a trailing /, may trigger an assert. An assert will cause the Apache process to abort.
Ruby Gem developers report:
The patch for CVE-2013-4363 was insufficiently verified so the combined regular expression for verifying gem version remains vulnerable following CVE-2013-4363.
RubyGems validates versions with a regular expression that is vulnerable to denial of service due to backtracking. For specially crafted RubyGems versions attackers can cause denial of service through CPU consumption.
Ruby Gem developers report:
RubyGems validates versions with a regular expression that is vulnerable to denial of service due to backtracking. For specially crafted RubyGems versions attackers can cause denial of service through CPU consumption.
Ruby developers report:
Any time a string is converted to a floating point value, a specially crafted string can cause a heap overflow. This can lead to a denial of service attack via segmentation faults and possibly arbitrary code execution. Any program that converts input of unknown origin to floating point values (especially common when accepting JSON) are vulnerable.
The Samba project reports:
Samba 4.0.x before 4.0.11 and 4.1.x before 4.1.1, when LDAP or HTTP is provided over SSL, uses world-readable permissions for a private key, which allows local users to obtain sensitive information by reading the key file, as demonstrated by access to the local filesystem on an AD domain controller.
The Samba project reports:
Samba versions 3.2.0 and above (all versions of 3.2.x, 3.3.x, 3.4.x, 3.5.x, 3.6.x, 4.0.x and 4.1.x) do not check the underlying file or directory ACL when opening an alternate data stream.
According to the SMB1 and SMB2+ protocols the ACL on an underlying file or directory should control what access is allowed to alternate data streams that are associated with the file or directory.
The nginx project reports:
Ivan Fratric of the Google Security Team discovered a bug in nginx, which might allow an attacker to bypass security restrictions in certain configurations by using a specially crafted request, or might have potential other impact (CVE-2013-4547).
Adobe reports:
These updates address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system.
The OpenSSH development team reports:
A memory corruption vulnerability exists in the post- authentication sshd process when an AES-GCM cipher (aes128-gcm@openssh.com or aes256-gcm@openssh.com) is selected during kex exchange.
If exploited, this vulnerability might permit code execution with the privileges of the authenticated user and may therefore allow bypassing restricted shell/command configurations.
Either upgrade to 6.4 or disable AES-GCM in the server configuration. The following sshd_config option will disable AES-GCM while leaving other ciphers active:
Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,aes192-cbc,aes256-cbc
Quassel IRC developers report:

Dwayne Litzenberger reports:
In PyCrypto before v2.6.1, the Crypto.Random pseudo-random number generator (PRNG) exhibits a race condition that may cause it to generate the same 'random' output in multiple processes that are forked from each other.

The wordpress development team reports:
- Block unsafe PHP unserialization that could occur in limited situations and setups, which can lead to remote code execution.
- Prevent a user with an Author role, using a specially crafted request, from being able to create a post "written by" another user.
- Fix insufficient input validation that could result in redirecting or leading a user to another website.
Additionally, we've adjusted security restrictions around file uploads to mitigate the potential for cross-site scripting.
node.js developers report
This release contains a security fix for the http server implementation, please upgrade as soon as possible.
Cross-Site Request Forgery
When a user submits changes to a bug right after another user did, a midair collision page is displayed to inform the user about changes recently made. This page contains a token which can be used to validate the changes if the user decides to submit his changes anyway. A regression in Bugzilla 4.4 caused this token to be recreated if a crafted URL was given, even when no midair collision page was going to be displayed, allowing an attacker to bypass the token check and abuse a user to commit changes on his behalf.
Cross-Site Request Forgery
When an attachment is edited, a token is generated to validate changes made by the user. Using a crafted URL, an attacker could force the token to be recreated, allowing him to bypass the token check and abuse a user to commit changes on his behalf.
Cross-Site Scripting
Some parameters passed to editflagtypes.cgi were not correctly filtered in the HTML page, which could lead to XSS.
Cross-Site Scripting

Werner Koch reports:
Special crafted input data may be used to cause a denial of service against GPG (GnuPG's OpenPGP part) and some other OpenPGP implementations. All systems using GPG to process incoming data are affected..
xinetd would execute configured TCPMUX services without dropping privilege to match the service configuration allowing the service to run with same privilege as the xinetd process (root).
PolarSSL Project reports:
The researchers Cyril Arnaud and Pierre-Alain Fouque investigated the PolarSSL RSA implementation and discovered a bias in the implementation of the Montgomery multiplication that we used. For which they then show that it can be used to mount an attack on the RSA key. Although their test attack is done on a local system, there seems to be enough indication that this can properly be performed from a remote system as well.
All versions prior to PolarSSL 1.2.9 and 1.3.0 are affected if a third party can send arbitrary handshake messages to your server.
If correctly executed, this attack reveals the entire private RSA key after a large number of attack messages (> 600.000 on a local machine) are sent to show the timing differences.
Graphite developers report:
This release contains several security fixes for cross-site scripting (XSS) as well as a fix for a remote-execution exploit in graphite-web (CVE-2013-5903).
The Django project reports:
These releases address a denial-of-service attack against Django's authentication framework. All users of Django are encouraged to upgrade immediately.
Problem Description:
The nullfs(5) implementation of the VOP_LINK(9) VFS operation does not check whether the source and target of the link are both in the same nullfs instance. It is therefore possible to create a hardlink from a location in one nullfs instance to a file in another, as long as the underlying (source) filesystem is the same.
Impact:
If multiple nullfs views into the same filesystem are mounted in different locations, a user with read access to one of these views and write access to another will be able to create a hard link from the latter to a file in the former, even though they are, from the user's perspective, different filesystems. The user may thereby gain write access to files which are nominally on a read-only filesystem.
Problem Description:
As is commonly the case, the IPv6 and ATM network layer ioctl request handlers are written in such a way that an unrecognized request is passed on unmodified to the link layer, which will either handle it or return an error code.
Network interface drivers, however, assume that the SIOCSIFADDR, SIOCSIFBRDADDR, SIOCSIFDSTADDR and SIOCSIFNETMASK requests have been handled at the network layer, and therefore do not perform input validation or verify the caller's credentials. Typical link-layer actions for these requests may include marking the interface as "up" and resetting the underlying hardware.
Impact:
An unprivileged user with the ability to run arbitrary code can cause any network interface in the system to perform the link layer actions associated with a SIOCSIFADDR, SIOCSIFBRDADDR, SIOCSIFDSTADDR or SIOCSIFNETMASK ioctl request; or trigger a kernel panic by passing a specially crafted address structure which causes a network interface driver to dereference an invalid pointer.
Although this has not been confirmed, the possibility that an attacker may be able to execute arbitrary code in kernel context cannot be ruled out.

The Django project reports:
These releases address a directory-traversal vulnerability in one of Django's built-in template tags. While this issue requires some fairly specific factors to be exploitable, we encourage all users of Django to upgrade promptly.
Subversion Project reports:
svnserve takes a --pid-file option which creates a file containing the process id it is running as. It does not take steps to ensure that the file it has been directed at is not a symlink. If the pid file is in a directory writeable by unprivileged users, the destination could be replaced by a symlink allowing for privilege escalation. svnserve does not create a pid file by default.
All versions are only vulnerable when the --pid-file=ARG option is used.

Note that Libgcrypt is used by GnuPG 2.x and thus this release fixes the above problem. The fix for GnuPG less than 2.0 can be found in the just released GnuPG 1.4.14.
Puppet Labs reports:
By using the `resource_type` service, an attacker could cause puppet to load arbitrary Ruby files from the puppet master node's file system. While this behavior is not enabled by default, `auth.conf` settings could be modified to allow it. The exploit requires local file system access to the Puppet Master.
Puppet Module Tool (PMT) did not correctly control permissions of modules it installed, instead transferring permissions that existed when the module was built.
Mageia security team reports:
It was discovered that Little CMS did not properly verify certain memory allocations. If a user or automated system using Little CMS were tricked into opening a specially crafted file, an attacker could cause Little CMS to crash (CVE-2013-4160).
Paul Bakker reports:
A bug in the logic of the parsing of PEM encoded certificates in x509parse_crt() can result in an infinite loop, thus hogging processing power.
While parsing a Certificate message during the SSL/TLS handshake, PolarSSL extracts the presented certificates and sends them on to be parsed. As the RFC specifies that the certificates in the Certificate message are always X.509 certificates in DER format, bugs in the decoding of PEM certificates should normally not be triggerable via the SSL/TLS handshake.
Versions of PolarSSL prior to 1.1.7 in the 1.1 branch and prior to 1.2.8 in the 1.2 branch call the generic x509parse_crt() function for parsing during the handshake. x509parse_crt() is a generic functions that wraps parsing of both PEM-encoded and DER-formatted certificates. As a result it is possible to craft a Certificate message that includes a PEM encoded certificate in the Certificate message that triggers the infinite loop.
The Samba project reports:
All current released versions of Samba are vulnerable to a denial of service on an authenticated or guest connection. A malformed packet can cause the smbd server to loop the CPU performing memory allocations and preventing any further service.
A connection to a file share, or a local account is needed to exploit this problem, either authenticated or unauthenticated if guest connections are allowed.

Simon Tatham reports:
This [0.63] release fixes multiple security holes in previous versions of PuTTY, which can allow an SSH-2 server to make PuTTY overrun or underrun buffers and crash. [...]
These vulnerabilities can be triggered before host key verification, which means that you are not even safe if you trust the server you think you're connecting to, since it could be spoofed over the network and the host key check would not detect this before the attack could take place.
Additionally, when PuTTY authenticated with a user's private key, the private key or information equivalent to it was accidentally kept in PuTTY's memory for the rest of its run, where it could be retrieved by other processes reading PuTTY's memory, or written out to swap files or crash dumps. This release fixes that as well.
Typo Security Team reports:
It has been discovered that TYPO3 Core is vulnerable to Cross-Site Scripting and Remote Code Execution.
TYPO3 bundles flash files for video and audio playback. Old versions of FlowPlayer and flashmedia are susceptible to Cross-Site Scripting. No authentication is required to exploit this vulnerability.
The file upload component and the File Abstraction Layer are failing to check for denied file extensions, which allows authenticated editors (even with limited permissions) to upload php files with arbitrary code, which can then be executed in web server's context.

ISC reports:
A specially crafted query that includes malformed rdata can cause named to terminate with an assertion failure while rejecting the malformed query.
A Yarom and Falkner paper reports:
Flush+Reload is a cache side-channel attack that monitors access to data in shared pages. In this paper we demonstrate how to use the attack to extract private encryption keys from GnuPG. The high resolution and low noise of the Flush+Reload attack enables a spy program to recover over 98% of the bits of the private key in a single decryption or signing round. Unlike previous attacks, the attack targets the last level L3 cache. Consequently, the spy program and the victim do not need to share the execution core of the CPU. The attack is not limited to a traditional OS and can be used in a virtualised environment, where it can attack programs executing in a different VM.
OpenAFS Project reports:
The small size of the DES key space permits an attacker to brute force a cell's service key and then forge traffic from any user within the cell. The key space search can be performed in under 1 day at a cost of around $100 using publicly available services.
Subversion Project reports:
Subversion's mod_dav_svn Apache HTTPD server module will trigger an assertion on some requests made against a revision root. This can lead to a DoS. If assertions are disabled it will trigger a read overflow which may cause a SEGFAULT (or equivalent) or undefined behavior.
Commit access is required to exploit this.
suPHP developer Sebastian Marsching reports:
When the suPHP_PHPPath was set, mod_suphp would use the specified PHP executable to pretty-print PHP source files (MIME type x-httpd-php-source or application/x-httpd-php-source).
However, it would not sanitize the environment. Thus a user that was allowed to use the SetEnv directive in a .htaccess file (AllowOverride FileInfo) could make PHP load a malicious configuration file (e.g. loading malicious extensions).
As the PHP process for highlighting the source file was run with the privileges of the user Apache HTTPd was running as, a local attacker could probably execute arbitrary code with the privileges of this user.
Apache HTTP SERVER PROJECT reports:
mod_dav: Sending a MERGE request against a URI handled by mod_dav_svn with the source href (sent as part of the request body as XML) pointing to a URI that is not configured for DAV will trigger a segfault.
mod_session_dbd: Make sure that dirty flag is respected when saving sessions, and ensure the session ID is changed each time the session changes. This changes the format of the updatesession SQL statement. Existing configurations must be changed.
Red Hat Security Response Team reports:
Gallery upstream has released 3.0.9 version, correcting two security flaws:
Issue #1 - Improper stripping of URL fragments in flowplayer SWF file might lead to reply attacks (a different flaw than CVE-2013-2138).
Issue #2 - gallery3: Multiple information exposure flaws in data rest core module.
The PHP development team reports:
ext/xml/xml.c in PHP before 5.3.27 does not properly consider parsing depth, which allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a crafted document that is processed by the xml_parse_into_struct function.
The PHP development team reports:
Integer overflow in the SdnToJewish function in jewish.c in the Calendar component in PHP before 5.3.26 and 5.4.x before 5.4.16 allows context-dependent attackers to cause a denial of service (application hang) via a large argument to the jdtojewish function.
Adobe reports:
These updates address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system.
Squid project reports:
Due to incorrect data validation Squid is vulnerable to a denial of service attack when processing specially crafted HTTP requests
This problem allows any client who can generate HTTP requests to perform a denial of service attack on the Squid service.
Mark Dowd reports:
Vulnerability 1. Remote Heap Overflow: If an attacker sends a packet larger than 1024 bytes that gets stored temporarily (which occurs many times - such as when sending a ZRTP Hello packet), a heap overflow will occur, leading to potential arbitrary code execution on the vulnerable host.
Vulnerability 2. Multiple Stack Overflows: ZRTPCPP contains multiple stack overflows that arise when preparing a response to a client's ZRTP Hello packet.
Vulnerability 3. Information Leaking / Out of Bounds Reads: The ZRTPCPP library performs very little validation regarding the expected size of a packet versus the actual amount of data received. This can lead to both information leaking and out of bounds data reads (usually resulting in a crash). Information leaking can be performed for example by sending a malformed ZRTP Ping packet.
Ruby Developers report:
Ruby's SSL client implements hostname identity check but it does not properly handle hostnames in the certificate that contain null bytes.
The OTRS Project reports:
An attacker with a valid agent login could manipulate URLs leading to SQL injection. An attacker with a valid agent login could manipulate URLs in the ITSM ConfigItem search, leading to a JavaScript code injection (XSS) problem.
The mod_rewrite module in the Apache HTTP Server 2.2.x before 2.2.25 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to execute arbitrary commands via an HTTP request containing an escape sequence for a terminal emulator.
mod_dav: Sending a MERGE request against a URI handled by mod_dav_svn with the source href (sent as part of the request body as XML) pointing to a URI that is not configured for DAV will trigger a segfault.
The phpMyAdmin development team reports:
The import.php script was vulnerable to GLOBALS variable injection. Therefore, an attacker could manipulate any configuration parameter.
This vulnerability can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required form.
The Apache Software Foundation reports:

cURL developers report:
libcurl is vulnerable to a case of bad checking of the input data which may lead to heap corruption.
The function curl_easy_unescape() decodes URL-encoded strings to raw binary data. URL-encoded octets are represented with %HH combinations where HH is a two-digit hexadecimal number. The decoded string is written to an allocated memory area that the function returns to the caller.
The function takes a source string and a length parameter, and if the length provided is 0 the function will instead use strlen() to figure out how much data to parse.
The "%HH" parser wrongly only considered the case where a zero byte would terminate the input. If a length-limited buffer was passed in which ended with a '%' character which was followed by two hexadecimal digits outside of the buffer libcurl was allowed to parse alas without a terminating zero, libcurl would still parse that sequence as well. The counter for remaining data to handle would then be decreased too much and wrap to become a very large integer and the copying would go on too long and the destination buffer that is allocated on the heap would get overwritten.
We consider it unlikely that programs allow user-provided strings unfiltered into this function. Also, only the not zero-terminated input string use case is affected by this flaw. Exploiting this flaw for gain is probably possible for specific circumstances but we consider the general risk for this to be low.
The curl command line tool is not affected by this problem as it doesn't use this function.
There are no known exploits available at this time.
Puppet Developers report:
When making REST api calls, the puppet master takes YAML from an untrusted client, deserializes it, and then calls methods on the resulting object. A YAML payload can be crafted to cause the deserialization to construct an instance of any class available in the ruby process, which allows an attacker to execute code contained in the payload.
The OTRS Project reports:
An attacker with a valid agent login could manipulate URLs in the ticket watch mechanism to see contents of tickets they are not permitted to see.
Due to insufficient permission checks in the virtual memory system, a tracing process (such as a debugger) may be able to modify portions of the traced process's address space to which the traced process itself does not have write access.
The Apache Software Foundation reports:
A heap overflow exists in the processing of the PrefixList attribute optionally used in conjunction with Exclusive Canonicalization, potentially allowing arbitary code execution. If verification of the signature occurs prior to actual evaluation of a signing key, this could be exploited by an unauthenticated attacker.
The Tor Project reports:
Disable middle relay queue overfill detection code due to possible guard discovery attack
Simon McVittie reports:

If you use an unencrypted connection to a "legacy Jabber" (pre-XMPP) server, this version of Gabble will not connect until you make one of these configuration changes:
. upgrade the server software to something that supports XMPP 1.0; or
. use an encrypted "old SSL" connection, typically on port 5223 (old-ssl); or
. turn off "Encryption required (TLS/SSL)" (require-encryption).
freedesktop.org reports:
Ilja van Sprundel, a security researcher with IOActive, has discovered a large number of issues in the way various X client libraries handle the responses they receive from servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues.
Most of these issues stem from the client libraries trusting the server to send correct protocol data, and not verifying that the values will not overflow or cause other damage. Most of the time X clients & servers are run by the same user, with the server more privileged from the clients, so this is not a problem, but there are scenarios in which a privileged client can be connected to an unprivileged server, for instance, connecting a setuid X client (such as a screen lock program) to a virtual X server (such as Xvfb or Xephyr) which the user has modified to return invalid data, potentially allowing the user to escalate their privileges.
The vulnerabilities include:
Integer overflows calculating memory needs for replies.
Sign extension issues calculating memory needs for replies.
Buffer overflows due to not validating length or offset values in replies.
Integer overflows parsing user-specified files.
Unbounded recursion parsing user-specified files.
Memory corruption due to unchecked return values.
No advisory has been released yet.
schpw.c in the kpasswd service in kadmind in MIT Kerberos 5 (aka krb5) before 1.11.3 does not properly validate UDP packets before sending responses, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged packet that triggers a communication loop, as demonstrated by krb_pingpong.nasl, a related issue to CVE-1999-0103. [CVE-2002-2443].

The script contrib/hook-scripts/check-mime-type.pl does not escape argv arguments to 'svnlook' that start with a hyphen. This could be used to cause 'svnlook', and hence check-mime-type.pl, to error out.
The script contrib/hook-scripts/svn-keyword-check.pl parses filenames from the output of 'svnlook changed' and passes them to a further shell command (equivalent to the 'system()' call of the C standard library) without escaping them. This could be used to run arbitrary shell commands in the context of the user whom the pre-commit script runs as (the user who owns the repository).

Thomas Sibley reports:
We discovered a number of security vulnerabilities which affect both RT 3.8.x and RT 4.0.x. We are releasing RT versions 3.8.17 and 4.0.13 to resolve these vulnerabilities, as well as patches which apply atop all released versions of 3.8 and 4.0.
The vulnerabilities addressed by 3.8.17, 4.0.13, and the below patches include the following:
RT 4.0.0 and above are vulnerable to a limited privilege escalation leading to unauthorized modification of ticket data. The DeleteTicket right and any custom lifecycle transition rights may be bypassed by any user with ModifyTicket. This vulnerability is assigned CVE-2012-4733.
RT 3.8.0 and above include a version of bin/rt that uses semi-predictable names when creating tempfiles. This could possibly be exploited by a malicious user to overwrite files with permissions of the user running bin/rt. This vulnerability is assigned CVE-2013-3368.
RT 3.8.0 and above allow calling of arbitrary Mason components (without control of arguments) for users who can see administration pages. This could be used by a malicious user to run private components which may have negative side-effects. This vulnerability is assigned CVE-2013-3369.
RT 3.8.0 and above allow direct requests to private callback components. Though no callback components ship with RT, this could be used to exploit an extension or local callback which uses the arguments passed to it insecurely. This vulnerability is assigned CVE-2013-3370.
RT 3.8.3 and above are vulnerable to cross-site scripting (XSS) via attachment filenames. The vector is difficult to exploit due to parsing requirements. Additionally, RT 4.0.0 and above are vulnerable to XSS via maliciously-crafted "URLs" in ticket content when RT's "MakeClicky" feature is configured. Although not believed to be exploitable in the stock configuration, a patch is also included for RTIR 2.6.x to add bulletproofing. These vulnerabilities are assigned CVE-2013-3371.
RT 3.8.0 and above are vulnerable to an HTTP header injection limited to the value of the Content-Disposition header. Injection of other arbitrary response headers is not possible. Some (especially older) browsers may allow multiple Content-Disposition values which could lead to XSS. Newer browsers contain security measures to prevent this. Thank you to Dominic Hargreaves for reporting this vulnerability. This vulnerability is assigned CVE-2013-3372.
RT 3.8.0 and above are vulnerable to a MIME header injection in outgoing email generated by RT. The vectors via RT's stock templates are resolved by this patchset, but any custom email templates should be updated to ensure that values interpolated into mail headers do not contain newlines. This vulnerability is assigned CVE-2013-3373.
RT 3.8.0 and above are vulnerable to limited session re-use when using the file-based session store, Apache::Session::File. RT's default session configuration only uses Apache::Session::File for Oracle. RT instances using Oracle may be locally configured to use the database-backed Apache::Session::Oracle, in which case sessions are never re-used. The extent of session re-use is limited to information leaks of certain user preferences and caches, such as queue names available for ticket creation. Thank you to Jenny Martin for reporting the problem that lead to discovery of this vulnerability. This vulnerability is assigned CVE-2013-3374.
CVE reports:
Stack-based buffer overflow in the error function in ssg/ssgParser.cxx in PLIB 1.8.5 allows remote attackers to execute arbitrary code via a crafted 3d model file that triggers a long error message, as demonstrated by a .ase file.
Secunia reports:
A vulnerability has been discovered in PLIB, which can be exploited by malicious people to compromise an application using the library. The vulnerability is caused due to a boundary error within the "ulSetError()" function (src/util/ulError.cxx) when creating the error message, which can be exploited to overflow a static buffer.
Successful exploitation allows the execution of arbitrary code but requires that the attacker can e.g. control the content of an overly long error message passed to the "ulSetError()" function.
The vulnerability is confirmed in version 1.8.5. Other versions may also be affected.
Originally reported in TORCS by Andres Gomez.

A stack-based buffer overflow might occur in a worker process process while handling a specially crafted request, potentially resulting in arbitrary code execution. [CVE-2013-2028]
A security problem related to CVE-2013-2028 was identified, affecting some previous nginx versions if proxy_pass to untrusted upstream HTTP servers is used.
The problem may lead to a denial of service or a disclosure of a worker process memory on a specially crafted response from an upstream proxied server. [CVE-2013-2070]
strongSwan security team reports:
If the openssl plugin is used for ECDSA signature verification an empty, zeroed or otherwise invalid signature is handled as a legitimate one. Both IKEv1 and IKEv2 are affected.
Affected are only installations that have enabled and loaded the OpenSSL crypto backend (--enable-openssl). Builds using the default crypto backends are not affected.
Jenkins Security Advisory reports:
This advisory announces multiple security vulnerabilities that were found in Jenkins core.
SECURITY-63 / CVE-2013-2034
This creates a cross-site request forgery (CSRF) vulnerability on Jenkins master, where an anonymous attacker can trick an administrator to execute arbitrary code on Jenkins master by having him open a specifically crafted attack URL.
There's also a related vulnerability where the permission check on this ability is done imprecisely, which may affect those who are running Jenkins instances with a custom authorization strategy plugin.
SECURITY-67 / CVE-2013-2033
This creates a cross-site scripting (XSS) vulnerability, where an attacker with a valid user account on Jenkins can execute JavaScript in the browser of other users, if those users are using certain browsers.
SECURITY-69 / CVE-2013-2034
This is another CSRF vulnerability that allows an attacker to cause a deployment of binaries to Maven repositories. This vulnerability has the same CVE ID as SEUCRITY-63.
SECURITY-71 / CVE-2013-1808
This creates a cross-site scripting (XSS) vulnerability.
Insufficient input validation in the NFS server allows an attacker to cause the underlying file system to treat a regular file as a directory.

The phpMyAdmin development team reports:
In some PHP versions, the preg_replace() function can be tricked into executing arbitrary PHP code on the server. This is done by passing a crafted argument as the regular expression, containing a null byte. phpMyAdmin does not correctly sanitize an argument passed to preg_replace() when using the "Replace table prefix" feature, opening the way to this vulnerability..
This vulnerability can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users to access the required form.
phpMyAdmin can be configured to save an export file on the web server, via its SaveDir directive. With this in place, it's possible, either via a crafted filename template or a crafted table name, to save a double extension file like foobar.php.sql. In turn, an Apache webserver on which there is no definition for the MIME type "sql" (the default) will treat this saved file as a ".php" script, leading to remote code execution.
This vulnerability can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users to access the required form. Moreover, the SaveDir directive is empty by default, so a default configuration is not vulnerable. The $cfg['SaveDir'] directive must be configured, and the server must be running Apache with mod_mime to be exploitable.
tinc-vpn.org reports:

NVIDIA Unix security team reports:
When the NVIDIA driver for the X Window System is operated in "NoScanout" mode, and an X client installs an ARGB cursor that is larger than the expected size (64x64 or 256x256, depending on the driver version), the driver will overflow a buffer. This can cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution. Because the X server runs as setuid root in many configurations, an attacker could potentially use this vulnerability in those configurations to gain root privileges.
Opera reports:
Fixed a moderately severe issue, as reported by Attila Suszte.
Subversion team reports:

PostgreSQL project reports:
The PostgreSQL Global Development Group has released a security update to all current versions of the PostgreSQL database system, including versions 9.2.4, 9.1.9, 9.0.13, and 8.4.17. This update fixes a high-exposure security vulnerability in versions 9.0 and later. All users of the affected versions are strongly urged to apply the update *immediately*.
A major security issue (for versions 9.x only) fixed in this release, [CVE-2013-1899](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1899), makes it possible for a connection request containing a database name that begins with "-" to be crafted that can damage or destroy files within a server's data directory. Anyone with access to the port the PostgreSQL server listens on can initiate this request. This issue was discovered by Mitsumasa Kondo and Kyotaro Horiguchi of NTT Open Source Software Center.
Two lesser security fixes are also included in this release: [CVE-2013-1900](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1900), wherein random numbers generated by contrib/pgcrypto functions may be easy for another database user to guess (all versions), and [CVE-2013-1901](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1901), which mistakenly allows an unprivileged user to run commands that could interfere with in-progress backups (for versions 9.x only).

Firebird Project reports:
The FirebirdSQL server is vulnerable to a stack buffer overflow that can be triggered when an unauthenticated user sends a specially crafted packet. The result can lead to remote code execution as the user which runs the FirebirdSQL server.
Secunia reports:
A vulnerability has been reported in OptiPNG, which can be exploited by malicious people to potentially compromise a user's system.
The vulnerability is caused due to a use-after-free error related to the palette reduction functionality. No further information is currently available.
Success exploitation may allow execution of arbitrary code.
The PHP development team reports:
PHP does not validate the relationship between the soap.wsdl_cache_dir directive and the open_basedir directive, which allows remote attackers to bypass intended access restrictions by triggering the creation of cached SOAP WSDL files in an arbitrary directory.
The SOAP parser in PHP allows remote attackers to read arbitrary files via a SOAP WSDL file containing an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue in the soap_xmlParseFile and soap_xmlParseMemory functions.
High-Tech Bridge Security Research Lab reports:
The CSRF vulnerability exists due to insufficient verification of the HTTP request origin in "/admin.php" script. A remote attacker can trick a logged-in administrator to visit a specially crafted webpage and create arbitrary PHP file on the remote server.
The path traversal vulnerability exists due to insufficient filtration of user-supplied input in "dl" HTTP GET parameter passed to "/install.php" script. The script is present on the system after installation by default, and can be accessed by attacker without any restrictions.
libexif project security advisory:
A number of remotely exploitable issues were discovered in libexif and exif, with effects ranging from information leakage to potential remote code execution.
Adobe reports:
These updates address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system.
Moses Mendoza reports:
A vulnerability found in Puppet could allow an authenticated client to cause the master to execute arbitrary code while responding to a catalog request. Specifically, in order to exploit the vulnerability, the puppet master must be made to invoke the 'template' or 'inline_template' functions during catalog compilation.
A vulnerability found in Puppet could allow an authenticated client to connect to a puppet master and perform unauthorized actions. Specifically, given a valid certificate and private key, an agent could retrieve catalogs from the master that it is not authorized to access or it could poison the puppet master's caches for any puppet-generated data that supports caching such as catalogs, nodes, facts, and resources. The extent and severity of this vulnerability varies depending on the specific configuration of the master: for example, whether it is using storeconfigs or not, which version, whether it has access to the cache or not, etc.
A vulnerability has been found in Puppet which could allow authenticated clients to execute arbitrary code on agents that have been configured to accept kick connections. This vulnerability is not present in the default configuration of puppet agents, but if they have been configured to listen for incoming connections ('listen=true'), and the agent's auth.conf has been configured to allow access to the `run` REST endpoint, then a client could construct an HTTP request which could execute arbitrary code. The severity of this issue is exacerbated by the fact that puppet agents typically run as root.
A vulnerability has been found in Puppet that could allow a client negotiating a connection to a master to downgrade the master's SSL protocol to SSLv2. This protocol has been found to contain design weaknesses. This issue only affects systems running older versions (pre 1.0.0) of openSSL. Newer versions explicitly disable SSLv2.
A vulnerability found in Puppet could allow unauthenticated clients to send requests to the puppet master which would cause it to load code unsafely. While there are no reported exploits, this vulnerability could cause issues like those described in Rails CVE-2013-0156. This vulnerability only affects puppet masters running Ruby 1.9.3 and higher.
This vulnerability affects puppet masters 0.25.0 and above. By default, auth.conf allows any authenticated node to submit a report for any other node. This can cause issues with compliance. The defaults in auth.conf have been changed.

A vulnerability found in Puppet could allow an authenticated client to execute arbitrary code on a puppet master that is running in the default configuration, or an agent with `puppet kick` enabled. Specifically, a properly authenticated and connected puppet agent could be made to construct an HTTP PUT request for an authorized report that actually causes the execution of arbitrary code on the master.

Perl developers report:
In order to prevent an algorithmic complexity attack against its hashing mechanism, perl will sometimes recalculate keys and redistribute the contents of a hash. This mechanism has made perl robust against attacks that have been demonstrated against other systems.
Research by Yves Orton has recently uncovered a flaw in the rehashing code which can result in pathological behavior. This flaw could be exploited to carry out a denial of service attack against code that uses arbitrary user input as hash keys.
Because using user-provided strings as hash keys is a very common operation, we urge users of perl to update their perl executable as soon as possible.

MFSA 2013-29 Use-after-free in HTML Editor
Typo Security Team reports:
Extbase Framework - Failing to sanitize user input, the Extbase database abstraction layer is susceptible to SQL Injection. TYPO3 sites which have no Extbase extensions installed are not affected. Extbase extensions are affected if they use the Query Object Model and relation values are user generated input. Credits go to Helmut Hummel and Markus Opahle who discovered and reported the issue.
Access tracking mechanism - Failing to validate user provided input, the access tracking mechanism allows redirects to arbitrary URLs. To fix this vulnerability, we had to break existing behaviour of TYPO3 sites that use the access tracking mechanism (jumpurl feature) to transform links to external sites. The link generation has been changed to include a hash that is checked before redirecting to an external URL. This means that old links that have been distributed (e.g. by a newsletter) will not work any more.

moderate: XSS in mod_proxy_balancer CVE-2012-4558
A XSS flaw affected the mod_proxy_balancer manager interface.
Todd Miller reports:
The flaw may allow someone with physical access to a machine that is not password-protected to run sudo commands without knowing the logged in user's password. On systems where sudo is the principal way of running commands as root, such as on Ubuntu and Mac OS X, there is a greater chance that the logged in user has run sudo before and thus that an attack would succeed.
Todd Miller reports:
A (potentially malicious) program run by a user with sudo access may be able to bypass the "tty_ticket" constraints. In order for this to succeed there must exist on the machine a terminal device that the user has previously authenticated themselves on via sudo within the last time stamp timeout (5 minutes by default).
Mark Evans reports:
Unfortnately there is a security vulnerability in Dragonfly when used with Rails which would potentially allow an attacker to run arbitrary code on a host machine using carefully crafted requests.

The OTRS Project reports:
This advisory covers vulnerabilities discovered in the OTRS core system. This is a variance of the XSS vulnerability, where an attacker could send a specially prepared HTML email to OTRS which would cause JavaScript code to be executed in your browser while displaying the email. In this case this is achieved by using javascript source attributes with whitespaces.
Affected by this vulnerability are all releases of OTRS 2.4.x up to and including 2.4.14, 3.0.x up to and including 3.0.16 and 3.1.x up to and including 3.1.10.

Ruby developers report:
Unrestricted entity expansion can lead to a DoS vulnerability in REXML. (The CVE identifier will be assigned later.) We strongly recommend to upgrade ruby.
When reading text nodes from an XML document, the REXML parser can be coerced in to allocating extremely large string objects which can consume all of the memory on a machine, causing a denial of service.
Michael Scherer reports:
This is a relatively minor tmp file usage issue.
The Django Project reports:
These security releases fix four issues: one potential phishing vector, one denial-of-service vector, an information leakage issue, and a range of XML vulnerabilities.
Host header poisoning
an attacker could cause Django to generate and display URLs that link to arbitrary domains. This could be used as part of a phishing attack. These releases fix this problem by introducing a new setting, ALLOWED_HOSTS, which specifies a whitelist of domains your site is known to respond to.
Important: by default Django 1.3.6 and 1.4.4 set ALLOWED_HOSTS to allow all hosts. This means that to actually fix the security vulnerability you should define this setting yourself immediately after upgrading.
Formset denial-of-service
an attacker can abuse Django's tracking of the number of forms in a formset to cause a denial-of-service attack. This has been fixed by adding a default maximum number of forms of 1,000. You can still manually specify a bigger max_num, if you wish, but 1,000 should be enough for anyone.
XML attacks
Django's serialization framework was vulnerable to attacks via XML entity expansion and external references; this is now fixed. However, if you're parsing arbitrary XML in other parts of your application, we recommend you look into the defusedxml Python packages which remedy this anywhere you parse XML, not just via Django's serialization framework.
Data leakage via admin history log
Django's admin interface could expose supposedly-hidden information via its history log. This has been fixed.
No advisory has been released yet.

Drupal Security Team reports:
Drupal core's Image module allows for the on-demand generation of image derivatives. This capability can be abused by requesting a large number of new derivatives which can fill up the server disk space, and which can cause a very high CPU load. Either of these effects may lead to the site becoming unavailable or unresponsive.
Garth Mollett reports:
A file descriptor overflow issue in the use of FD_SET() in nss-pam-ldapd can lead to a stack-based buffer overflow. An attacker could, under some circumstances, use this flaw to cause a process that has the NSS or PAM module loaded to crash or potentially execute arbitrary code.
Cross-Site Scripting
When viewing a single bug report, which is the default, the bug ID is validated and rejected if it is invalid. But when viewing several bug reports at once, which is specified by the format=multiple parameter, invalid bug IDs can go through and are sanitized in the HTML page itself. But when an invalid page format is passed to the CGI script, the wrong HTML page is called and data are not correctly sanitized, which can lead to XSS.
Information Leak
When running a query in debug mode, the generated SQL query used to collect the data is displayed. The way this SQL query is built permits the user to determine if some confidential field value (such as a product name) exists. This problem only affects Bugzilla 4.0.9 and older. Newer releases are not affected by this issue.

Aaron Patterson reports:
The attr_protected method allows developers to specify a blacklist of model attributes which users should not be allowed to assign to. By using a specially crafted request, attackers could circumvent this protection and alter values that were meant to be protected.
All users running an affected release should either upgrade or use one of the work arounds immediately. Users should also consider switching from attr_protected to the whitelist method attr_accessible which is not vulnerable to this attack.
Jenkins Security Advisory reports:
This advisory announces multiple security vulnerabilities that were found in Jenkins core.
- One of the vulnerabilities allows cross-site request forgery (CSRF) attacks on Jenkins master, which causes an user to make unwanted actions on Jenkins. Another vulnerability enables cross-site scripting (XSS) attacks, which has the similar consequence. Another vulnerability allowed an attacker to bypass the CSRF protection mechanism in place, thereby mounting more CSRF attackes. These attacks allow an attacker without direct access to Jenkins to mount an attack.
- In the fourth vulnerability, a malicious user of Jenkins can trick Jenkins into building jobs that he does not have direct access to.
- And lastly, a vulnerability allows a malicious user of Jenkins to mount a denial of service attack by feeding a carefully crafted payload to Jenkins.
Multiple cross-site scripting (XSS) vulnerabilities
Multiple scripts are vulnerable to XSS attacks.
Aaron Patterson reports:
When parsing certain JSON documents, the JSON gem can be coerced in to creating Ruby symbols in a target system. Since Ruby symbols are not garbage collected, this can result in a denial of service attack.
The same technique can be used to create objects in a target system that act like internal objects. These "act alike" objects can be used to bypass certain security mechanisms and can be used as a spring board for SQL injection attacks in Ruby on Rails.
Ruby developers report:
RDoc documentation generated by rdoc bundled with ruby are vulnerable to an XSS exploit. All ruby users are recommended to update ruby to newer version which includes security-fixed RDoc. If you are publishing RDoc documentation generated by rdoc, you are recommended to apply a patch for the documentaion or re-generate it with security-fixed RDoc.

Wordpress reports:
WordPress 3.5.1 also addresses the following security issues:
- A server-side request forgery vulnerability and remote port scanning using pingbacks. This vulnerability, which could potentially be used to expose information and compromise a site, affects all previous WordPress versions. This was fixed by the WordPress security team. We'd like to thank security researchers Gennady Kovshenin and Ryan Dewhurst for reviewing our work.
- Two instances of cross-site scripting via shortcodes and post content. These issues were discovered by Jon Cave of the WordPress security team.
- A cross-site scripting vulnerability in the external library Plupload. Thanks to the Moxiecode team for working with us on this, and for releasing Plupload 1.5.5 to address this issue.
Cross-site scripting (XSS) vulnerability
Jonas Obrist reports: The security issue allows users with limited admin access to elevate their privileges through XSS injection using the page_attribute template tag. Only users with admin access and the permission to edit at least one django CMS page object could exploit this vulnerability. Websites that do not use the page_attribute template tag are not affected.
Drupal Security Team reports:

Host target list parsing routine in ettercap 0.7.4-series prior to 0.7.4.1 and 0.7.5-series is prone to the stack-based buffer overflow that may lead to the code execution with the privileges of the ettercap process.
In order to trigger this vulnerability, user or service that use ettercap should be tricked to pass the crafted list of targets via the "-j" option.
US CERT reports:
Java 7 Update 10 and earlier versions of Java 7 contain a vulnerability that can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
The Java JRE plug-in provides its own Security Manager. Typically, a web applet runs with a security manager provided by the browser or Java Web Start plugin. Oracle's document states, "If there is a security manager already installed, this method first calls the security manager's checkPermission method with a RuntimePermission("setSecurityManager") permission to ensure it's safe to replace the existing security manager. This may result in throwing a SecurityException".
By leveraging the vulnerability in the Java Management Extensions (JMX) MBean components, unprivileged Java code can access restricted classes. By using that vulnerability in conjunction with a second vulnerability involving the Reflection API and the invokeWithArguments method of the MethodHandle class, an untrusted Java applet can escalate its privileges by calling the the setSecurityManager() function to allow full privileges, without requiring code signing. Oracle Java 7 update 10 and earlier Java 7 versions are affected. The invokeWithArguments method was introduced with Java 7, so therefore Java 6 is not affected.
This vulnerability is being attacked in the wild, and is reported to be incorporated into exploit kits. Exploit code for this vulnerability is also publicly available.
Esteban Guillardoy from Immunity Inc. additionally clarifies on the recursive reflection exploitation technique:
The real issue is in the native sun.reflect.Reflection.getCallerClass method.
We can see the following information in the Reflection source code:
Returns the class of the method realFramesToSkip frames up the stack (zero-based), ignoring frames associated with java.lang.reflect.Method.invoke() and its implementation.
So what is happening here is that they forgot to skip the frames related to the new Reflection API and only the old reflection API is taken into account.
This exploit does not only affect Java applets, but every piece of software that relies on the Java Security Manager for sandboxing executable code is affected: malicious code can totally disable Security Manager.
For users who are running native Web browsers with enabled Java plugin, the workaround is to remove the java/icedtea-web port and restart all browser instances.
For users who are running Linux Web browser flavors, the workaround is either to disable the Java plugin in browser or to upgrade linux-sun-* packages to the non-vulnerable version.
It is not recommended to run untrusted applets using appletviewer, since this may lead to the execution of the malicious code on vulnerable versions on JDK/JRE.

Ruby on Rails team reports:
Two high-risk vulnerabilities have been discovered:
(CVE-2013-0155) There is a vulnerability when Active Record is used in conjunction with JSON parameter parsing.
Due to the way Active Record interprets parameters in combination with the way that JSON parameters are parsed, it is possible for an attacker to issue unexpected database queries with "IS NULL" or empty "WHERE" clauses. This issue does not let an attacker insert arbitrary values into an SQL query, however they can cause the query to check for NULL or eliminate a WHERE clause when most users would not expect it.
(CVE-2013-0156) There are multiple weaknesses in the parameter parsing code for Ruby on Rails which allows attackers to bypass authentication systems, inject arbitrary SQL, inject and execute arbitrary code, or perform a DoS attack on a Rails application.
The parameter parsing code of Ruby on Rails allows applications to automatically cast values from strings to certain data types. Unfortunately the type casting code supported certain conversions which were not suitable for performing on user-provided data including creating Symbols and parsing YAML. These unsuitable conversions can be used by an attacker to compromise a Rails application.
Ruby on Rails team reports:
There is a SQL injection vulnerability in Active Record in ALL versions. Due to the way dynamic finders in Active Record extract options from method parameters, a method parameter can mistakenly be used as a scope. Carefully crafted requests can use the scope to inject arbitrary SQL.
Jenkins Security Advisory reports:
This advisory announces a security vulnerability that was found in Jenkins core.
An attacker can then use this master cryptographic key to mount remote code execution attack against the Jenkins master, or impersonate arbitrary users in making REST API calls.
There are several factors that mitigate some of these problems that may apply to specific installations.
- The particular attack vector is only applicable on Jenkins instances that have slaves attached to them, and allow anonymous read access.
- Jenkins allows users to re-generate the API tokens. Those re-generated API tokens cannot be impersonated by the attacker.
The Django Project reports:
Host header poisoning
Several earlier Django security releases focused on the issue of poisoning the HTTP Host header, causing Django to generate URLs pointing to arbitrary, potentially-malicious domains.
In response to further input received and reports of continuing issues following the previous release, we're taking additional steps to tighten Host header validation. Rather than attempt to accommodate all features HTTP supports here, Django's Host header validation attempts to support a smaller, but far more common, subset:
- Hostnames must consist of characters [A-Za-z0-9] plus hyphen ('-') or dot ('.').
- IP addresses -- both IPv4 and IPv6 -- are permitted.
- Port, if specified, is numeric.
Any deviation from this will now be rejected, raising the exception django.core.exceptions.SuspiciousOperation.
Redirect poisoning
Also following up on a previous issue: in July of this year, we made changes to Django's HTTP redirect classes, performing additional validation of the scheme of the URL to redirect to (since, both within Django's own supplied applications and many third-party applications, accepting a user-supplied redirect target is a common pattern).
Since then, two independent audits of the code turned up further potential problems. So, similar to the Host-header issue, we are taking steps to provide tighter validation in response to reported problems (primarily with third-party applications, but to a certain extent also within Django itself). This comes in two parts:
- A new utility function, django.utils.http.is_safe_url, is added; this function takes a URL and a hostname, and checks that the URL is either relative, or if absolute matches the supplied hostname. This function is intended for use whenever user-supplied redirect targets are accepted, to ensure that such redirects cannot lead to arbitrary third-party sites.
- All of Django's own built-in views -- primarily in the authentication system -- which allow user-supplied redirect targets now use is_safe_url to validate the supplied URL.
The FreeType Project reports:
Some vulnerabilities in the BDF implementation have been fixed. Users of this font format should upgrade.
MoinMoin developers report the following vulnerabilities as fixed in version 1.9.6:
- remote code execution vulnerability in twikidraw/anywikidraw action,
- path traversal vulnerability in AttachFile action,
- XSS issue, escape page name in rss link.
CVE entries at MITRE furher clarify:
Multiple unrestricted file upload vulnerabilities in the (1) twikidraw (action/twikidraw.py) and (2) anywikidraw (action/anywikidraw.py) actions in MoinMoin before 1.9.6 allow remote authenticated users with write permissions to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in an unspecified directory, as exploited in the wild in July 2012.
Directory traversal vulnerability in the _do_attachment_move function in the AttachFile action (action/AttachFile.py) in MoinMoin 1.9.3 through 1.9.5 allows remote attackers to overwrite arbitrary files via a .. (dot dot) in a file name.
Cross-site scripting (XSS) vulnerability in the rsslink function in theme/__init__.py in MoinMoin 1.9.5 allows remote attackers to inject arbitrary web script or HTML via the page name in a rss link.

All versions of Charybdis are vulnerable to a remotely-triggered crash bug caused by code originating from ircd-ratbox 2.0. (Incidentally, this means all versions since ircd-ratbox 2.0 are also vulnerable.)
puppet -- multiple vulnerabilities
Arbitrary file read on the puppet master from authenticated clients (high). It is possible to construct an HTTP get request from an authenticated client with a valid certificate that will return the contents of an arbitrary file on the Puppet master that the master has read-access to.
Arbitrary file delete/D.O.S on Puppet Master from authenticated clients (high). Given a Puppet master with the "Delete" directive allowed in auth.conf for an authenticated host, an attacker on that host can send a specially crafted Delete request that can cause an arbitrary file deletion on the Puppet master, potentially causing a denial of service attack. Note that this vulnerability does *not* exist in Puppet as configured by default.
Insufficient input validation for agent hostnames (low). An attacker could trick the administrator into signing an attacker's certificate rather than the intended one by constructing specially crafted certificate requests containing specific ANSI control sequences. It is possible to use the sequences to rewrite the order of text displayed to an administrator such that display of an invalid certificate and valid certificate are transposed. If the administrator signs the attacker's certificate, the attacker can then man-in-the-middle the agent.
OTRS Security Advisory reports:
This advisory covers vulnerabilities discovered in the OTRS core system. This is a variance of the XSS vulnerability, where an attacker could send a specially prepared HTML email to OTRS which would cause JavaScript code to be executed in your browser while displaying the email.

This is a variance of the XSS vulnerability, where an attacker could send a specially prepared HTML email to OTRS which would cause JavaScript code to be executed in your browser while displaying the email in Firefox and Opera. In this case this is achieved with an invalid HTML structure with nested tags.
OTRS Security Advisory reports:
This advisory covers vulnerabilities discovered in the OTRS core system. Due to the XSS vulnerability in Internet Explorer an attacker could send a specially prepared HTML email to OTRS which would cause JavaScript code to be executed in your Internet Explorer while displaying the email.
Squid developers report:
Due to missing input validation Squid cachemgr.cgi tool is vulnerable to a denial of service attack when processing specially crafted requests.
This problem allows any client able to reach the cachemgr.cgi to perform a denial of service attack on the service host.
The nature of the attack may cause secondary effects through resource consumption on the host server.
Opera reports:
When loading GIF images into memory, Opera should allocate the correct amount of memory to store that image. Specially crafted image files can cause Opera to allocate the wrong amount of memory. Subsequent data may then overwrite unrelated memory with attacker-controlled data. This can lead to a crash, which may also execute that data as code.
Adobe reports:
These updates address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system.
The Apache Software Foundation reports:
The CSRF prevention filter could be bypassed if a request was made to a protected resource without a session identifier present in the request.
The Apache Software Foundation reports:
When using the NIO connector with sendfile and HTTPS enabled, if a client breaks the connection while reading the response an infinite loop is entered leading to a denial of service.
The Apache Software Foundation reports:
When using FORM authentication it was possible to bypass the security constraint checks in the FORM authenticator by appending "/j_security_check" to the end of the URL if some other component (such as the Single-Sign-On valve) had called request.setUserPrincipal() before the call to FormAuthenticator#authenticate().
ISC reports:
BIND 9 nameservers using the DNS64 IPv6 transition mechanism are vulnerable to a software defect that allows a crafted query to crash the server with a REQUIRE assertion failure. Remote exploitation of this defect can be achieved without extensive effort, resulting in a denial-of-service (DoS) vector against affected servers.
David Relson reports:
Fix a heap corruption in base64 decoder on invalid input. Analysis and patch by Julius Plenz, [FU Berlin, Germany].
The YUI team reports:
Vulnerability in YUI 2.4.0 through YUI 2.9.0
A XSS vulnerability has been discovered in some YUI 2 .swf files from versions 2.4.0 through 2.9.0. This defect allows JavaScript injection exploits to be created against domains that host affected YUI .swf files.
If your site loads YUI 2 from a CDN (yui.yahooapis.com, ajax.googleapis.com, etc.) and not from your own domain, you are not affected. YUI 3 is not affected by this issue.
Problem description:
A programming error in the handling of some Linux system calls may result in memory locations being accessed without proper validation.
Problem description:
The internal authentication server of hostapd does not sufficiently validate the message length field of EAP-TLS messages.
Problem description:
The BIND daemon would crash when a query is made on a resource record with RDATA that exceeds 65535 bytes.
The BIND daemon would lock up when a query is made on specific combinations of RDATA.
Opera reports:
When requesting pages using HTTP, Opera temporarily stores the response in a buffer. In some cases, Opera may incorrectly allocate too little space for a buffer, and may then store too much of the response in that buffer. This causes a buffer overflow, which in turn can lead to a memory corruption and crash. It is possible to use this crash to execute the overflowing data as code, which may be controlled by an attacking site.
Lighttpd security advisory reports:
Certain Connection header values will trigger an endless loop, for example: "Connection: TE,,Keep-Alive"
On receiving such value, lighttpd will enter an endless loop, detecting an empty token but not incrementing the current string position, and keep reading the ',' again and again.
This bug was introduced in 1.4.31, when we fixed an "invalid read" bug (it would try to read the byte before the string if it started with ',', although the value wasn't actually used).

Sebastien Helleu reports:
Untrusted command for function hook_process could lead to execution of commands, because of shell expansions.
Workaround with a non-patched version: remove/unload all scripts calling function hook_process (for maximum safety).
The following security issues have been discovered in Bugzilla:
Information Leak
If the visibility of a custom field is controlled by a product or a component of a product you cannot see, their names are disclosed in the JavaScript code generated for this custom field despite they should remain confidential.
Calling the User.get method with a 'groups' argument leaks the existence of the groups depending on whether an error is thrown or not. This method now also throws an error if the user calling this method does not belong to these groups (independently of whether the groups exist or not).
Trying to mark an attachment in a bug you cannot see as obsolete discloses its description in the error message. The description of the attachment is now removed from the error message.
Cross-Site Scripting
Due to incorrectly filtered field values in tabular reports, it is possible to inject code leading to XSS.
A vulnerability in swfstore.swf from YUI2 allows JavaScript injection exploits to be created against domains that host this affected YUI .swf file.
Typo Security Team reports:
TYPO3 Backend History Module - Due to missing encoding of user input, the history module is susceptible to SQL Injection and Cross-Site Scripting. A valid backend login is required to exploit this vulnerability. Credits go to Thomas Worm who discovered and reported the issue.
TYPO3 Backend API - Failing to properly HTML-encode user input the tree render API (TCA-Tree) is susceptible to Cross-Site Scripting. TYPO3 Versions below 6.0 does not make us of this API, thus is not exploitable, if no third party extension is installed which uses this API. A valid backend login is required to exploit this vulnerability. Credits go to Richard Brain who discovered and reported the issue.

The official ruby site reports:
Carefully crafted sequence of strings can cause a denial of service attack on the service that parses the sequence to create a Hash object by using the strings as keys. For instance, this vulnerability affects web application that parses the JSON data sent from untrusted entity.
This vulnerability is similar to CVS-2011-4815 for ruby 1.8.7. ruby 1.9 versions were using modified MurmurHash function but it's reported that there is a way to create sequence of strings that collide their hash values each other. This fix changes the Hash function of String object from the MurmurHash to SipHash 2-4.
The Apache Software Foundation reports:
Three weaknesses in Tomcat's implementation of DIGEST authentication were identified and resolved:
- Tomcat tracked client rather than server nonces and nonce count.
- When a session ID was present, authentication was bypassed.
- The user name and password were not checked before when indicating that a nonce was stale.
These issues reduced the security of DIGEST authentication making replay attacks possible in some circumstances.
The first issue was identified by Tilmann Kuhn. The second and third issues were identified by the Tomcat security team during the code review resulting from the first issue.
The Apache Software Foundation reports:
The checks that limited the permitted size of request headers were implemented too late in the request parsing process for the HTTP NIO connector. This enabled a malicious user to trigger an OutOfMemoryError by sending a single request with very large headers. This issue was identified by Josh Spiewak.
Adobe reports:
These vulnerabilities could cause a crash and potentially allow an attacker to take control of the affected system.
Opera reports:
CORS (Cross-Origin Resource Sharing) allows web pages to retrieve the contents of pages from other sites, with their permission, as they would appear for the current user. When requests are made in this way, the browser should only allow the page content to be retrieved if the target site sends the correct headers that give permission for their contents to be used in this way. Specially crafted requests may trick Opera into thinking that the target site has given permission when it had not done so. This can result in the contents of any target page being revealed to untrusted sites, including any sensitive information or session IDs contained within the source of those pages.
Also reported are vulnerabilities involving SVG graphics and XSS.
Adobe reports:
These vulnerabilities could cause a crash and potentially allow an attacker to take control of the affected system.

The official ruby site reports:
A vulnerability was found that file creation routines can create unintended files by strategically inserting NUL(s) in file paths. This vulnerability has been reported as CVE-2012-4522.
Ruby can handle arbitrary binary patterns as Strings, including NUL chars. On the other hand OSes and other libraries tend not. They usually treat a NUL as an End of String mark. So to interface them with Ruby, NUL chars should properly be avoided.
However methods like IO#open did not check the filename passed to them, and just passed those strings to lower layer routines. This led to create unintentional files.
The official ruby site reports:
Vulnerabilities found for Exception#to_s, NameError#to_s, and name_err_mesg_to_s() which is Ruby interpreter-internal API. A malicious user code can bypass $SAFE check by utilizing one of those security holes.
Ruby's $SAFE mechanism enables untrusted user codes to run in $SAFE >= 4 mode. This is a kind of sandboxing so some operations are restricted in that mode to protect other data outside the sandbox.
The problem found was around this mechanism. Exception#to_s, NameError#to_s, and name_err_mesg_to_s() interpreter-internal API was not correctly handling the $SAFE bits so a String object which is not tainted can destructively be marked as tainted using them. By using this an untrusted code in a sandbox can modify a formerly-untainted string destructively.
Ruby 1.8 once had a similar security issue. It fixed Exception#to_s and NameError#to_s, but name_err_mesg_to_str() issue survived previous security fix
BestPractical report:
All versions of RT are vulnerable to an email header injection attack. Users with ModifySelf or AdminUser can cause RT to add arbitrary headers or content to outgoing mail. Depending on the scrips that are configured, this may be be leveraged for information leakage or phishing.
RT 4.0.0 and above and RTFM 2.0.0 and above contain a vulnerability due to lack of proper rights checking, allowing any privileged user to create Articles in any class.
All versions of RT with cross-site-request forgery (CSRF) protection (RT 3.8.12 and above, RT 4.0.6 and above, and any instances running the security patches released 2012-05-22) contain a vulnerability which incorrectly allows though CSRF requests which toggle ticket bookmarks.
All versions of RT are vulnerable to a confused deputy attack on the user. While not strictly a CSRF attack, users who are not logged in who are tricked into following a malicious link may, after supplying their credentials, be subject to an attack which leverages their credentials to modify arbitrary state. While users who were logged in would have observed the CSRF protection page, users who were not logged in receive no such warning due to the intervening login process. RT has been extended to notify users of pending actions during the login process.
RT 3.8.0 and above are susceptible to a number of vulnerabilities concerning improper signing or encryption of messages using GnuPG; if GnuPG is not enabled, none of the following affect you.
Drupal Security Team reports:
Arbitrary PHP code execution
A bug in the installer code was identified that allows an attacker to re-install Drupal using an external database server under certain transient conditions. This could allow the attacker to execute arbitrary PHP code on the original server.
Information disclosure - OpenID module
For sites using the core OpenID module, an information disclosure vulnerability was identified that allows an attacker to read files on the local filesystem by attempting to log in to the site using a malicious OpenID server.

This vulnerability affects Exim instances built with DKIM enabled (this is the default for FreeBSD Exim port) and running verification of DKIM signatures on the incoming mail messages.
Phil Penncock reports:
This is a SECURITY release, addressing a CRITICAL remote code execution flaw in versions of Exim between 4.70 and 4.80 inclusive, when built with DKIM support (the default).
This security vulnerability can be exploited by anyone who can send email from a domain for which they control the DNS.
You are not vulnerable if you built Exim with DISABLE_DKIM or if you put this at the start of an ACL plumbed into acl_smtp_connect or acl_smtp_rcpt:
warn control = dkim_disable_verify
The Django Project reports:
Host header poisoning
Some parts of Django -- independent of end-user-written applications -- make use of full URLs, including domain name, which are generated from the HTTP Host header. Some attacks against this are beyond Django's ability to control, and require the web server to be properly configured; Django's documentation has for some time contained notes advising users on such configuration.
Django's own built-in parsing of the Host header is, however, still vulnerable, as was reported to us recently. The Host header parsing in Django 1.3 and Django 1.4 -- specifically, django.http.HttpRequest.get_host() -- was incorrectly handling username/password information in the header. Thus, for example, the following Host header would be accepted by Django when running on "validsite.com":
Host: validsite.com:random@evilsite.com
Using this, an attacker can cause parts of Django -- particularly the password-reset mechanism -- to generate and display arbitrary URLs to users.
To remedy this, the parsing in HttpRequest.get_host() is being modified; Host headers which contain potentially dangerous content (such as username/password pairs) now raise the exception django.core.exceptions.SuspiciousOperation.
Documentation of HttpOnly cookie option
As of Django 1.4, session cookies are always sent with the HttpOnly flag, which provides some additional protection from cross-site scripting attacks by denying client-side scripts access to the session cookie.
Though not directly a security issue in Django, it has been reported that the Django 1.4 documentation incorrectly described this change, by claiming that this was now the default for all cookies set by the HttpResponse.set_cookie() method.
The Django documentation has been updated to reflect that this only applies to the session cookie. Users of Django are encouraged to review their use of set_cookie() to ensure that the HttpOnly flag is being set or unset appropriately.

Due to an error in the dclock screensaver in xlockmore, users who explicitly use this screensaver or a random mix of screensavers using something like "xlockmore -mode random" may have their screen unlocked unexpectedly at a random time.
Thomas Swan reports:
xinetd allows for services to be configured with the TCPMUX or TCPMUXPLUS service types, which makes those services available on port 1, as per RFC 1078 [1], if the tcpmux-server service is enabled. When the tcpmux-server service is enabled, xinetd would expose _all_ enabled services via the tcpmux port, instead of just the configured service(s). This could allow a remote attacker to bypass firewall restrictions and access services via the tcpmux port.
The Zend Framework team reports:
The XmlRpc package of Zend Framework is vulnerable to XML eXternal Entity Injection attacks (both server and client). The SimpleXMLElement class (SimpleXML PHP extension) is used in an insecure way to parse XML data. External entities can be specified by adding a specific DOCTYPE element to XML-RPC requests. By exploiting this vulnerability an application may be coerced to open arbitrary files and/or TCP connections.
Additionally, the Zend_Dom, Zend_Feed, Zend_Soap, and Zend_XmlRpc components are vulnerable to XML Entity Expansion (XEE) vectors, leading to Denial of Service vectors. XEE attacks occur when the XML DOCTYPE declaration includes XML entity definitions that contain either recursive or circular references; this leads to CPU and memory consumption, making Denial of Service exploits trivial to implement.
Sitaram Chamarty reports:
I'm sorry to say there is a potential path traversal vulnerability in v3. Thanks to Stephane Chazelas for finding it and alerting me.
Can it affect you? This can only affect you if you are using wild card repos, *and* at least one of your patterns allows the string "../" to match multiple times.
How badly can it affect you? A malicious user who *also* has the ability to create arbitrary files in, say, /tmp (e.g., he has his own userid on the same box), can compromise the entire "git" user. Otherwise the worst he can do is create arbitrary repos in /tmp.
The phpMyAdmin development team reports:
When creating/modifying a trigger, event or procedure with a crafted name, it is possible to trigger an XSS.
To display information about the current phpMyAdmin version on the main page, a piece of JavaScript is fetched from the phpmyadmin.net website in non-SSL mode. A man-in-the-middle could modify this script on the wire to cause mischief.

Secunia reports:
A vulnerability has been discovered in OpenX, which can be exploited by malicious people to conduct SQL injection attacks.
Input passed via the "xajaxargs" parameter to www/admin/updates-history.php (when "xajax" is set to "expandOSURow") is not properly sanitised in e.g. the "queryAuditBackupTablesByUpgradeId()" function (lib/OA/Upgrade/DB_UpgradeAuditor.php) before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The vulnerability is confirmed in version 2.8.9. Prior versions may also be affected.
David Madison reports:
ePerl is a multipurpose Perl filter and interpreter program for Unix systems. The ePerl preprocessor contains an input validation error. The preprocessor allows foreign data to be "safely" included using the 'sinclude' directive.
The problem occurs when a file referenced by a 'sinclude' directive contains a 'include' directive; the contents of the file referred to by the second directive will be loaded and executed.
Kurt Seifried reports:
There is an issue in ImageMagick that is also present in GraphicsMagick. CVE-2011-3026 deals with libpng memory allocation, and limitations have been added so that a bad PNG can't cause the system to allocate a lot of memory and a denial of service. However on further investigation of ImageMagick, Tom Lane found that PNG malloc function (Magick_png_malloc) in turn calls AcquireMagickMemory with an improper size argument.
MITRE CVE team reports:
The SQLite functionality in PHP before 5.3.15 allows remote attackers to bypass the open_basedir protection mechanism via unspecified vectors.
MITRE CVE team reports:
Memory leak in the timezone functionality in PHP before 5.3.9 allows remote attackers to cause a denial of service (memory consumption) by triggering many strtotime function calls, which are not properly handled by the php_date_parse_tzfile cache.
ISC reports:
Prevents a crash when queried for a record whose RDATA exceeds 65535 bytes.
Prevents a crash when validating caused by using "Bad cache" data before it has been initialized.
ISC_QUEUE handling for recursive clients was updated to address a race condition that could cause a memory leak. This rarely occurred with UDP clients, but could be a significant problem for a server handling a steady rate of TCP queries.
A condition has been corrected where improper handling of zero-length RDATA could cause undesirable behavior, including termination of the named process.
Jenkins Security Advisory reports:
This advisory announces security vulnerabilities that were found in Jenkins core and several plugins.
- The first vulnerability in Jenkins core allows unprivileged users to insert data into Jenkins master, which can lead to remote code execution. For this vulnerability to be exploited, the attacker must have an HTTP access to a Jenkins master, and he must have a read access to Jenkins.
- The second vulnerability in Jenkins core is a cross-site scripting vulnerability. This allows an attacker to craft an URL that points to Jenkins, and if a legitimate user clicks this link, and the attacker will be able to hijack the user session.
- The third vulnerability is a cross-site scripting vulnerability in the Violations plugin
- The fourth vulnerability is a cross-site scripting vulnerability in The Continuous Integration Game plugin
Jean-Baptiste Kempf, on behalf of the VideoLAN project reports:
If successful, a malicious third party could crash the VLC media player process. Arbitrary code execution could be possible on some systems.
A security issue has been reported in Bacula, which can be exploited by malicious users to bypass certain security restrictions.
The security issue is caused due to an error within the implementation of console ACLs, which can be exploited to gain access to certain restricted functionality and e.g. dump resources.
Google Reports:
mod_pagespeed 0.10.22.6 is a security update that fixes two critical issues that affect earlier versions:
- CVE-2012-4001, a problem with validation of own host name.
- CVE-2012-4360, a cross-site scripting attack, which affects versions starting from 0.10.19.1.
The effect of the first problem is that it is possible to confuse mod_pagespeed about its own host name, and to trick it into fetching resources from other machines. This could be an issue if the HTTP server has access to machines that are not otherwise publicly visible.
The second problem would permit a hostile third party to execute JavaScript in users' browsers in context of the domain running mod_pagespeed, which could permit interception of users' cookies or data on the site.
Because of the severity of the two problems, users are strongly encouraged to update immediately.
Behavior Changes in the Update:
As part of the fix to the first issue, mod_pagespeed will not fetch resources from machines other than localhost if they are not explicitly mentioned in the configuration. This means that if you need resources on the server's domain to be handled by some other system, you'll need to explicitly use ModPagespeedMapOriginDomain or ModPagespeedDomain to authorize that.
freeRADIUS security team reports:
Overflow in EAP-TLS for 2.1.10, 2.1.11 and 2.1.12.
The issue was found by Timo Warns, and communicated to security@freeradius.org. A sample exploit for the issue was included in the notification.
The vulnerability was created in commit a368a6f4f4aaf on August 18, 2010. Vulnerable versions include 2.1.10, 2.1.11, and 2.1.12. Also anyone running the git "master" branch after August 18, 2010 is vulnerable.
All sites using TLS-based EAP methods and the above versions are vulnerable. The only configuration change which can avoid the issue is to disable EAP-TLS, EAP-TTLS, and PEAP.
An external attacker can use this vulnerability to over-write the stack frame of the RADIUS server, and cause it to crash. In addition, more sophisticated attacks may gain additional privileges on the system running the RADIUS server.
This attack does not require local network access to the RADIUS server. It can be done by an attacker through a WiFi Access Point, so long as the Access Point is configured to use 802.1X authentication with the RADIUS server.
Chong Yidong reports:
Paul Ling has found a security flaw in the file-local variables code in GNU Emacs.
When the Emacs user option `enable-local-variables' is set to `:safe' (the default value is t), Emacs should automatically refuse to evaluate `eval' forms in file-local variable sections. Due to the bug, Emacs instead automatically evaluates such `eval' forms. Thus, if the user changes the value of `enable-local-variables' to `:safe', visiting a malicious file can cause automatic execution of arbitrary Emacs Lisp code with the permissions of the user.
The bug is present in Emacs 23.2, 23.3, 23.4, and 24.1.
Wordpress reports:
Version 3.4.2 also fixes a few security issues and contains some security hardening. The vulnerabilities included potential privilege escalation and a bug that affects multisite installs with untrusted users. These issues were discovered and fixed by the WordPress security team.
MITRE CVE team reports:
Cross-site scripting (XSS) vulnerability in the reStructuredText (rst) parser in parser/text_rst.py in MoinMoin before 1.9.4, when docutils is installed or when "format rst" is set, allows remote attackers to inject arbitrary web script or HTML via a javascript: URL in the refuri attribute.
MoinMoin developers report:
If you have group NAMES containing "All" or "Known" or "Trusted", they behaved wrong until now (they erroneously included All/Known/Trusted users even if you did not list them as members), but will start working correctly with this changeset.
E.g. AllFriendsGroup:
- JoeDoe
AllFriendsGroup will now (correctly) include only JoeDoe. It (erroneously) contained all users (including JoeDoe) before.
E.g. MyTrustedFriendsGroup:
- JoeDoe
MyTrustedFriendsGroup will now (correctly) include only JoeDoe. It (erroneously) contained all trusted users and JoeDoe before.
Rui Hirokawa reports:
As of PHP 5.1.2, header() can no longer be used to send multiple response headers in a single call to prevent the HTTP Response Splitting Attack. header() only checks the linefeed (LF, 0x0A) as line-end marker, it doesn't check the carriage-return (CR, 0x0D).
However, some browsers including Google Chrome, IE also recognize CR as the line-end.
The current specification of header() still has the vulnerability against the HTTP header splitting attack.
A unspecified denial-of-service attack that could cause the bitcoin process to become unresponsive was found.
The following security issues have been discovered in Bugzilla:
LDAP Injection
When the user logs in using LDAP, the username is not escaped when building the uid=$username filter which is used to query the LDAP directory. This could potentially lead to LDAP injection.
Directory Browsing
Extensions are not protected against directory browsing and users can access the source code of the templates which may contain sensitive data. Directory browsing is blocked in Bugzilla 4.3.3 only, because it requires a configuration change in the Apache httpd.conf file to allow local .htaccess files to use Options -Indexes. To not break existing installations, this fix has not been backported to stable branches. The access to templates is blocked for all supported branches except the old 3.6 branch, because this branch doesn't have .htaccess in the bzr repository and cannot be fixed easily for existing installations without potentially conflicting with custom changes.
Jan Willamowius reports:
GNU Gatekeeper before 3.1 does not limit the number of connections to the status port, which allows remote attackers to cause a denial of service (connection and thread consumption) via a large number of connections.
Mediawiki reports:
(Bug 39700) Wikipedia administrator Writ Keeper discovered a stored XSS (HTML injection) vulnerability. This was possible due to the handling of link text on File: links for nonexistent files. MediaWiki 1.16 and later is affected.
(Bug 39180) User Fomafix reported several DOM-based XSS vulnerabilities, made possible by a combination of loose filtering of the uselang parameter, and JavaScript gadgets on various language Wikipedias.
(Bug 39180) During internal review, it was discovered that CSRF tokens, available via the api, were not protected with X-Frame-Options headers. This could lead to a CSRF vulnerability if the API response is embedded in an external website using using an iframe.
(Bug 39824) During internal review, it was discovered extensions were not always allowed to prevent the account creation action. This allowed users blocked by the GlobalBlocking extension to create accounts.
(Bug 39184) During internal review, it was discovered that password data was always saved to the local MediaWiki database even if authentication was handled by an extension, such as LDAP. This could allow a compromised MediaWiki installation to leak information about user's LDAP passwords. Additionally, in situations when an authentication plugin returned false in its strict function, this would allow old passwords to be used for accounts that did not exist in the external system, indefinitely.
(Bug 39823) During internal review, it was discovered that metadata about blocks, hidden by a user with suppression rights, was visible to administrators.
RedHat security team reports:
A denial of service flaw was found in the way Distributed Relational Database Architecture (DRDA) dissector of Wireshark, a network traffic analyzer, performed processing of certain DRDA packet capture files. A remote attacker could create a specially-crafted capture file that, when opened could lead to wireshark executable to consume excessive amount of CPU time and hang with an infinite loop.

The Coppermine Team reports:
The release covers several path disclosure vulnerabilities. If unpatched, it's possible to generate an error that will reveal the full path of the script. A remote user can determine the full path to the web root directory and other potentially sensitive information. Furthermore, the release covers a recently discovered XSS vulnerability that allows (if unpatched) a malevolent visitor to include own script routines under certain conditions.
US-CERT reports:
Oracle Java Runtime Environment (JRE) 1.7 contains a vulnerability that may allow an applet to call setSecurityManager in a way that allows setting of arbitrary permissions.
By leveraging the public, privileged getField() function, an untrusted Java applet can escalate its privileges by calling the setSecurityManager() function to allow full privileges, without requiring code signing.
This vulnerability is being actively exploited in the wild, and exploit code is publicly available.
This exploit does not only affect Java applets, but every piece of software that relies on the Java Security Manager for sandboxing executable code is affected: malicious code can totally disable Security Manager.
Matthias Andree reports:
Fetchmail version 6.3.9 enabled "all SSL workarounds" (SSL_OP_ALL) which contains a switch to disable a countermeasure against certain attacks against block ciphers that permit guessing the initialization vectors, providing that an attacker can make the application (fetchmail) encrypt some data for him -- which is not easily the case.
Stream ciphers (such as RC4) are unaffected.
Credits to Apple Product Security for reporting this.
RoundCube branch 0.8.x prior to the version 0.8.1 is prone to the cross-scripting attack (XSS) originating from incoming HTML e-mails: due to the lack of proper sanitization of JavaScript code inside the "href" attribute, sender could launch XSS attack when recipient opens the message in RoundCube interface.
KDE Security Advisory reports:
A flaw has been found which can allow malicious code to take advantage of an input validation failure in the Microsoft import filter in Calligra and KOffice. Exploitation can allow the attacker to gain control of the running process and execute code on its behalf.
SquidClamav developers report:
This release fix several security issues by escaping CGI parameters.
Prior to versions 6.7 and 5.8, CGI script clwarn.cgi was not properly sanitizing input variables, so they could be used to inject arbitrary strings to the generated page, leading to the cross-site scripting attacks.
SquidClamav developers report:
Add a workaround for a squidGuard bug that unescape the URL and send it back unescaped. This result in garbage staying into pipe of the system command call and could crash squidclamav on next read or return false information. This is specially true with URL containing the %0D or %0A character.
This vulnerability can be triggered only in configurations where external chained URL checker is configured via "squidguard" directive.
INN developers report:
Fixed a possible plaintext command injection during the negotiation of a TLS layer. The vulnerability detailed in CVE-2011-0411 affects the STARTTLS and AUTHINFO SASL commands. nnrpd now resets its read buffer upon a successful negotiation of a TLS layer. It prevents malicious commands, sent unencrypted, from being executed in the new encrypted state of the session.
XMPP Standards Foundation reports:
Some implementations of the XMPP Server Dialback protocol (RFC 3920/XEP-0220) have not been checking dialback responses to ensure that validated results are correlated with requests.
An attacking server could spoof one or more domains in communicating with a vulnerable server implementation, thereby avoiding the protections built into the Server Dialback protocol.
Derek Martin (rssh maintainer) reports:
John Barber reported a problem where, if the system administrator misconfigures rssh by providing too few access bits in the configuration file, the user will be given default permissions (scp) to the entire system, potentially circumventing any configured chroot. Fixing this required a behavior change: in the past, using rssh without a config file would give all users default access to use scp on an unchrooted system. In order to correct the reported bug, this feature has been eliminated, and you must now have a valid configuration file. If no config file exists, all users will be locked out.
Derek Martin (rssh maintainer) reports:
Henrik Erkkonen has discovered that, through clever manipulation of environment variables on the ssh command line, it is possible to circumvent rssh. As far as I can tell, there is no way to effect a root compromise, except of course if the root account is the one you're attempting to protect with rssh...
OTR developers report:
The otrl_base64_otr_decode() function and similar functions within OTR suffer from buffer overflows in the case of malformed input; specifically if a message of the format of "?OTR:===." is received then a zero-byte allocation is performed without a similar correlation between the subsequent base64 decoding write, as such it becomes possible to write between zero and three bytes incorrectly to the heap, albeit only with a value of '='.
Because this code path is highly utilized, specifically in the reception of instant messages over pidgin or similar, this vulnerability is considered severe even though in many platforms and circumstances the bug would yield an unexploitable state and result simply in denial of service.
The developers of OTR promptly fixed the errors and users of OTR are advised to upgrade the software at the next release cycle.
The OpenTTD Team reports:

The PostgreSQL Global Development Group reports:
The PostgreSQL Global Development Group today released security updates for all active branches of the PostgreSQL database system, including versions 9.1.5, 9.0.9, 8.4.13 and 8.3.20. This update patches security holes associated with libxml2 and libxslt, similar to those affecting other open source projects. All users are urged to update their installations at the first available opportunity
Users who are relying on the built-in XML functionality to validate external DTDs will need to implement a workaround, as this security patch disables that functionality. Users who are using xslt_process() to fetch documents or stylesheets from external URLs will no longer be able to do so. The PostgreSQL project regrets the need to disable both of these features in order to maintain our security standards. These security issues with XML are substantially similar to issues patched recently by the Webkit (CVE-2011-1774), XMLsec (CVE-2011-1425) and PHP5 (CVE-2012-0057) projects.
The phpMyAdmin development team reports:
Using a crafted table name, it was possible to produce a XSS : 1) On the Database Structure page, creating a new table with a crafted name 2) On the Database Structure page, using the Empty and Drop links of the crafted table name 3) On the Table Operations page of a crafted table, using the 'Empty the table (TRUNCATE)' and 'Delete the table (DROP)' links 4) On the Triggers page of a database containing tables with a crafted name, when opening the 'Add Trigger' popup 5) When creating a trigger for a table with a crafted name, with an invalid definition. Having crafted data in a database table, it was possible to produce a XSS : 6) When visualizing GIS data, having a crafted label name.
Typo Security Team reports:
It has been discovered that TYPO3 Core is vulnerable to Cross-Site Scripting, Information Disclosure, Insecure Unserialize leading to Arbitrary Code Execution.
TYPO3 Backend Help System - Due to a missing signature (HMAC) for a parameter in the view_help.php file, an attacker could unserialize arbitrary objects within TYPO3. We are aware of a working exploit, which can lead to arbitrary code execution. A valid backend user login or multiple successful cross site request forgery attacks are required to exploit this vulnerability.
TYPO3 Backend - Failing to properly HTML-encode user input in several places, the TYPO3 backend is susceptible to Cross-Site Scripting. A valid backend user is required to exploit these vulnerabilities.
TYPO3 Backend - Accessing the configuration module discloses the Encryption Key. A valid backend user with access to the configuration module is required to exploit this vulnerability.
TYPO3 HTML Sanitizing API - By not removing several HTML5 JavaScript events, the API method t3lib_div::RemoveXSS() fails to filter specially crafted HTML injections, thus is susceptible to Cross-Site Scripting. Failing to properly encode for JavaScript the API method t3lib_div::quoteJSvalue(), it is susceptible to Cross-Site Scripting.
TYPO3 Install Tool - Failing to properly sanitize user input, the Install Tool is susceptible to Cross-Site Scripting.
Matthias Andree reports:
With NTLM support enabled, fetchmail might mistake a server-side error message during NTLM protocol exchange for protocol data, leading to a SIGSEGV.
Also, with a carefully crafted NTLM challenge, a malicious server might cause fetchmail to read from a bad memory location, betraying confidential data. It is deemed hard, although not impossible, to steal other accounts' data.
The IcedTea project team reports:
CVE-2012-3422: Use of uninitialized instance pointers
An uninitialized pointer use flaw was found in IcedTea-Web web browser plugin. A malicious web page could use this flaw make IcedTea-Web browser plugin pass invalid pointer to a web browser. Depending on the browser used, it may cause the browser to crash or possibly execute arbitrary code.
The get_cookie_info() and get_proxy_info() call getFirstInTableInstance() with the instance_to_id_map hash as a parameter. If instance_to_id_map is empty (which can happen when plugin was recently removed), getFirstInTableInstance() returns an uninitialized pointer.
CVE-2012-3423: Incorrect handling of non 0-terminated strings
It was discovered that the IcedTea-Web web browser plugin incorrectly assumed that all strings provided by browser are NUL terminated, which is not guaranteed by the NPAPI (Netscape Plugin Application Programming Interface). When used in a browser that does not NUL terminate NPVariant NPStrings, this could lead to buffer over-read or over-write, resulting in possible information leak, crash, or code execution.
Mozilla browsers currently NUL terminate strings, however recent Chrome versions are known not to provide NUL terminated data.
The libcloud development team reports:
When establishing a secure (SSL / TLS) connection to a target server an invalid regular expression has been used for performing the hostname verification. Subset instead of the full target server hostname has been marked an an acceptable match for the given hostname. For example, certificate with a hostname field of "aexample.com" was considered a valid certificate for domain "example.com".
The phpMyAdmin development team reports:
The show_config_errors.php script does not include a library, so an error message shows the full path of this file, leading to possible further attacks.
Rails core team reports:
This version contains three important security fixes, please upgrade immediately.
One of security fixes impacts all users and is related to HTML escaping code. The other two fixes impacts people using select_tag's prompt option and strip_tags helper from ActionPack.
CVE-2012-3463 Potential XSS Vulnerability in select_tag prompt.
CVE-2012-3464 Potential XSS Vulnerability in the HTML escaping code.
CVE-2012-3465 XSS Vulnerability in strip_tags.
ISS reports:
sudosh2 and sudosh3 are vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the replay() function. By persuading a victim to replay a specially-crafted recorded sudo session, a local attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
Problem description:
BIND 9 stores a cache of query names that are known to be failing due to misconfigured name servers or a broken chain of trust. Under high query loads, when DNSSEC validation is active, it is possible for a condition to arise in which data from this cache of failing queries could be used before it was fully initialized, triggering an assertion failure.
GNU reports:
The recipe of the 'distcheck' target granted temporary world-write permissions on the extracted distdir. This introduced a locally exploitable race condition for those who run "make distcheck" with a non-restrictive umask (e.g., 022) in a directory that was accessible by others. A successful exploit would result in arbitrary code execution with the privileges of the user running "make distcheck".
It is important to stress that this vulnerability impacts not only the Automake package itself, but all packages with Automake-generated makefiles. For an effective fix it is necessary to regenerate the Makefile.in files with a fixed Automake version.

Apache reports:
Insecure handling of LD_LIBRARY_PATH was found that could lead to the current working directory to be searched for DSOs. This could allow a local user to execute code as root if an administrator runs apachectl from an untrusted directory.
The Django project reports:
Today the Django team is issuing multiple releases -- Django 1.3.2 and Django 1.4.1 -- to remedy security issues reported to us:
- Cross-site scripting in authentication views
- Denial-of-service in image validation
- Denial-of-service via get_image_dimensions()
All users are encouraged to upgrade Django immediately.
The following security issues have been discovered in Bugzilla:
Information Leak
Versions: 4.1.1 to 4.2.1, 4.3.1
In HTML bugmails, all bug IDs and attachment IDs are linkified, and hovering these links displays a tooltip with the bug summary or the attachment description if the user is allowed to see the bug or attachment. But when validating user permissions when generating the email, the permissions of the user who edited the bug were taken into account instead of the permissions of the addressee. This means that confidential information could be disclosed to the addressee if the other user has more privileges than the addressee. Plain text bugmails are not affected as bug and attachment IDs are not linkified.
Information Leak
Versions: 2.17.5 to 3.6.9, 3.7.1 to 4.0.6, 4.1.1 to 4.2.1, 4.3.1
The description of a private attachment could be visible to a user who hasn't permissions to access this attachment if the attachment ID is mentioned in a public comment in a bug that the user can see.
Tom Hendrikx reports:
It is possible to crash (SIGSEGV) a NSD child server process by sending it a DNS packet from any host on the internet and the per zone stats build option is enabled. A crashed child process will automatically be restarted by the parent process, but an attacker may keep the NSD server occupied restarting child processes by sending it a stream of such packets effectively preventing the NSD server to serve.
There is a DoS vulnerability in Action Pack digest authentication handling in authenticate_or_request_with_http_digest.
The RT development team reports:
RT::Authen::ExternalAuth 0.10 and below (for all versions of RT) are vulnerable to an escalation of privilege attack where the URL of a RSS feed of the user can be used to acquire a fully logged-in session as that user. CVE-2012-2770 has been assigned to this vulnerability.
Users of RT 3.8.2 and above should upgrade to RT::Authen::ExternalAuth 0.11, which resolves this vulnerability.
ISC reports:
An unexpected client identifier parameter can cause the ISC DHCP daemon to segmentation fault when running in DHCPv6 mode, resulting in a denial of service to further client requests. In order to exploit this condition, an attacker must be able to send requests to the DHCP server.
An error in the handling of malformed client identifiers can cause a DHCP server running affected versions (see "Impact") to enter a state where further client requests are not processed and the server process loops endlessly, consuming all available CPU cycles. Under normal circumstances this condition should not be triggered, but a non-conforming or malicious client could deliberately trigger it in a vulnerable server. In order to exploit this condition an attacker must be able to send requests to the DHCP server.
Two memory leaks have been found and fixed in ISC DHCP. Both are reproducible when running in DHCPv6 mode (with the -6 command-line argument.) The first leak is confirmed to only affect servers operating in DHCPv6 mode, but based on initial code analysis the second may theoretically affect DHCPv4 servers (though this has not been demonstrated.)
ISC reports:
High numbers of queries with DNSSEC validation enabled can cause an assertion failure in named, caused by using a 'bad cache' data structure before it has been initialized.
BIND 9 stores a cache of query names that are known to be failing due to misconfigured name servers or a broken chain of trust. Under high query loads when DNSSEC validation is active, it is possible for a condition to arise in which data from this cache of failing queries could be used before it was fully initialized, triggering an assertion failure.
This bug cannot be encountered unless your server is doing DNSSEC validation.
rubygem-activerecord -- multiple vulernabilities
Due to the way Active Record interprets parameters in combination with the way that Rack parses query parameters, it is possible for an attacker to issue unexpected database queries with "IS NULL" where clauses. This issue does *not* let an attacker insert arbitrary values into an SQL query, however they can cause the query to check for NULL where most users wouldn't expect it.
Due to the way Active Record handles nested query parameters, an attacker can use a specially crafted request to inject some forms of SQL into your application's SQL queries.
The PHP Development Team reports:
The release of PHP 5.4.15 and 5.4.5 fix a potential overflow in _php_stream_scandir
Marek Vavrusa and Lubos Slovak report:
It is possible to crash (SIGSEGV) a NSD child server process by sending it a non-standard DNS packet from any host on the internet. A crashed child process will automatically be restarted by the parent process, but an attacker may keep the NSD server occupied restarting child processes by sending it a stream of such packets effectively preventing the NSD server to serve.
The Changelog for version 1.2.1 says: Fixed a regression caused by 1.2.0[6] in which decompressing corrupt JPEG images (specifically, images in which the component count was erroneously set to a large value) would cause libjpeg-turbo to segfault.
A Heap-based buffer overflow was found in the way libjpeg-turbo decompressed certain corrupt JPEG images in which the component count was erroneously set to a large value. An attacker could create a specially-crafted JPEG image that, when opened, could cause an application using libpng to crash or, possibly, execute arbitrary code with the privileges of the user running the application.
Secunia Research reports:
Secunia Research has discovered a vulnerability in DokuWiki, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "ns" POST parameter in lib/exe/ajax.php (when "call" is set to "medialist" and "do" is set to "media") is not properly sanitised within the "tpl_mediaFileList()" function in inc/template.php before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
puppet -- multiple vulnerabilities
Arbitrary file read on the puppet master from authenticated clients (high). It is possible to construct an HTTP get request from an authenticated client with a valid certificate that will return the contents of an arbitrary file on the Puppet master that the master has read-access to.
Arbitrary file delete/D.O.S on Puppet Master from authenticated clients (high). Given a Puppet master with the "Delete" directive allowed in auth.conf for an authenticated host, an attacker on that host can send a specially crafted Delete request that can cause an arbitrary file deletion on the Puppet master, potentially causing a denial of service attack. Note that this vulnerability does *not* exist in Puppet as configured by default.
The last_run_report.yaml is world readable (medium). The most recent Puppet run report is stored on the Puppet master with world-readable permissions. The report file contains the context diffs of any changes to configuration on an agent, which may contain sensitive information that an attacker can then access. The last run report is overwritten with every Puppet run.
Arbitrary file read on the Puppet master by an agent (medium). This vulnerability is dependent upon vulnerability "last_run_report.yml is world readable" above. By creating a hard link of a Puppet-managed file to an arbitrary file that the Puppet master can read, an attacker forces the contents to be written to the puppet run summary. The context diff is stored in last_run_report.yaml, which can then be accessed by the attacker.
Insufficient input validation for agent hostnames (low). An attacker could trick the administrator into signing an attacker's certificate rather than the intended one by constructing specially crafted certificate requests containing specific ANSI control sequences. It is possible to use the sequences to rewrite the order of text displayed to an administrator such that display of an invalid certificate and valid certificate are transposed. If the administrator signs the attacker's certificate, the attacker can then man-in-the-middle the agent.
Agents with certnames of IP addresses can be impersonated (low). If an authenticated host with a certname of an IP address changes IP addresses, and a second host assumes the first host's former IP address, the second host will be treated by the puppet master as the first one, giving the second host access to the first host's catalog. Note: This will not be fixed in Puppet versions prior to the forthcoming 3.x. Instead, with this announcement IP-based authentication in Puppet < 3.x is deprecated.
Asterisk project reports:
Possible resource leak on uncompleted re-invite transactions.
Remote crash vulnerability in voice mail application.
Typo3 Security Report (TYPO3-CORE-SA-2012-003):
TYPO3 bundles and uses an external JavaScript and Flash Upload Library called swfupload. TYPO3 can be configured to use this Flash uploader. Input passed via the "movieName" parameter to swfupload.swf is not properly sanitised before being used in a call to "ExternalInterface.call()". This can be exploited to execute arbitrary script code in a user's browser session in context of an affected site. The existance of the swfupload library is sufficient to be vulnerable to the reported problem.
Zero Science Lab reports:
Input passed via the parameter 'sortby' is not properly sanitised before being returned to the user or used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code. The param 'num' is vulnerable to a XSS issue where the attacker can execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Problem description:
FreeBSD/amd64 runs on CPUs from different vendors. Due to varying behaviour of CPUs in 64 bit mode a sanity check of the kernel may be insufficient when returning from a system call.
Successful exploitation of the problem can lead to local kernel privilege escalation, kernel data corruption and/or crash. To exploit this vulnerability, an attacker must be able to run code with user privileges on the target system.
Problem description:
The named(8) server does not properly handle DNS resource records where the RDATA field is zero length, which may cause various issues for the servers handling them.
Resolving servers may crash or disclose some portion of memory to the client. Authoritative servers may crash on restart after transferring a zone containing records with zero-length RDATA fields. These would result in a denial of service, or leak of sensitive information.
Problem description:
There is a programming error in the DES implementation used in crypt() when handling input which contains characters that cannot be represented with 7-bit ASCII.
When the input contains characters with only the most significant bit set (0x80), that character and all characters after it will be ignored.
Problem description:
OpenSSL fails to clear the bytes used as block cipher padding in SSL 3.0 records when operating as a client or a server that accept SSL 3.0 handshakes. As a result, in each record, up to 15 bytes of uninitialized memory may be sent, encrypted, to the SSL peer. This could include sensitive contents of previously freed memory. [CVE-2011-4576]
OpenSSL support for handshake restarts for server gated cryptography (SGC) can be used in a denial-of-service attack. [CVE-2011-4619]
If an application uses OpenSSL's certificate policy checking when verifying X509 certificates, by enabling the X509_V_FLAG_POLICY_CHECK flag, a policy check failure can lead to a double-free. [CVE-2011-4109]
A weakness in the OpenSSL PKCS #7 code can be exploited using Bleichenbacher's attack on PKCS #1 v1.5 RSA padding also known as the million message attack (MMA). [CVE-2012-0884]
The asn1_d2i_read_bio() function, used by the d2i_*_bio and d2i_*_fp functions, in OpenSSL contains multiple integer errors that can cause memory corruption when parsing encoded ASN.1 data. This error can occur on systems that parse untrusted ASN.1 data, such as X.509 certificates or RSA public keys. [CVE-2012-2110]
Dwayne C. Litzenberger of PyCrypto reports:
In the ElGamal schemes (for both encryption and signatures), g is supposed to be the generator of the entire Z^*_p group. However, in PyCrypto 2.5 and earlier, g is more simply the generator of a random sub-group of Z^*_p.
The result is that the signature space (when the key is used for signing) or the public key space (when the key is used for encryption) may be greatly reduced from its expected size of log(p) bits, possibly down to 1 bit (the worst case if the order of g is 2).
While it has not been confirmed, it has also been suggested that an attacker might be able to use this fact to determine the private key.
Anyone using ElGamal keys should generate new keys as soon as practical.
Any additional information about this bug will be tracked at https://bugs.launchpad.net/pycrypto/+bug/985164

Skinny Channel Driver Remote Crash Vulnerability.
ImageMagick reports:
Three vulnerabilities have been identified in ImageMagick's handling of JPEG and TIFF files. With these vulnerabilities, it is possible to cause a denial of service situation in the target system.
Mantis reports:
Roland Becker and Damien Regad (MantisBT developers) found that any user able to report issues via the SOAP interface could also modify any bugnotes (comments) created by other users. In a default/typical MantisBT installation, SOAP API is enabled and any user can sign up to report new issues. This vulnerability therefore impacts upon many public facing MantisBT installations.
Roland Becker (MantisBT developer) found that the delete_attachments_threshold permission was not being checked when a user attempted to delete an attachment from an issue. The more generic update_bug_threshold permission was being checked instead. MantisBT administrators may have been under the false impression that their configuration of the delete_attachments_threshold was successfully preventing unwanted users from deleting attachments.

All BGP sessions established by the attacked router will be closed and its BGP routing disrupted.
David Verdin reports:
Multiple vulnerabilities have been discovered in Sympa archive management that allow to skip the scenario-based authorization mechanisms.
This vulnerability allows the attacker to:
- display the archives management page ('arc_manage')
- download the list's archives
- delete the list's archives
ISC reports:
Processing of DNS resource records where the rdata field is zero length may cause various issues for the servers handling them.
Processing of these records may lead to unexpected outcomes. Recursive servers may crash or disclose some portion of memory to the client. Secondary servers may crash on restart after transferring a zone containing these records. Master servers may corrupt zone data if the zone option "auto-dnssec" is set to "maintain". Other unexpected problems that are not listed here may also be encountered.
Impact: This issue primarily affects recursive nameservers. Authoritative nameservers will only be impacted if an administrator configures experimental record types with no data. If the server is configured this way, then secondaries can crash on restart after transferring that zone. Zone data on the master can become corrupted if the zone with those records has named configured to manage the DNSSEC key rotation.
The PostgreSQL Global Development Group reports:
Today the PHP, OpenBSD and FreeBSD communities announced updates to patch a security hole involving their crypt() hashing algorithms. This issue is described in CVE-2012-2143. This vulnerability also affects a minority of PostgreSQL users, and will be fixed in an update release on June 4, 2012.
Affected users are those who use the crypt(text, text) function with DES encryption in the optional pg_crypto module. Passwords affected are those that contain characters that cannot be represented with 7-bit ASCII. If a password contains a character that has the most significant bit set (0x80), and DES encryption is used, that character and all characters after it will be ignored.
Networkupstools project reports:
NUT server (upsd), from versions 2.4.0 to 2.6.3, are exposed to crashes when receiving random data from the network.
This issue is related to the way NUT parses characters, especially from the network. Non printable characters were missed from strings operation (such as strlen), but still copied to the buffer, causing an overflow.
Asterisk project reports:

HAProxy reports:
A flaw was reported in HAProxy where, due to a boundary error when copying data into the trash buffer, an external attacker could cause a buffer overflow. Exploiting this flaw could lead to the execution of arbitrary code, however it requires non-default settings for the global.tune.bufsize configuration option (must be set to a value greater than the default), and also that header rewriting is enabled (via, for example, the regrep or rsprep directives). This flaw is reported against 1.4.20, prior versions may also be affected.

Internal audits of the RT codebase have uncovered a number of security vulnerabilities in RT. We are releasing versions 3.8.12 and 4.0.6 to resolve these vulnerabilities, as well as patches which apply atop all released versions of 3.8 and 4.0.
The vulnerabilities addressed by 3.8.12, 4.0.6, and the below patches include the following:
The previously released tool to upgrade weak password hashes as part of CVE-2011-0009 was an incomplete fix and failed to upgrade passwords of disabled users.
RT versions 3.0 and above contain a number of cross-site scripting (XSS) vulnerabilities which allow an attacker to run JavaScript with the user's credentials. CVE-2011-2083 is assigned to this vulnerability.
RT versions 3.0 and above are vulnerable to multiple information disclosure vulnerabilities. This includes the ability for privileged users to expose users' previous password hashes -- this vulnerability is particularly dangerous given RT's weak hashing previous to the fix in CVE-2011-0009. A separate vulnerability allows privileged users to obtain correspondence history for any ticket in RT. CVE-2011-2084 is assigned to this vulnerability.
All publicly released versions of RT are vulnerable to cross-site request forgery (CSRF). CVE-2011-2085 is assigned to this vulnerability.
We have also added a separate configuration option ($RestrictLoginReferrer) to prevent login CSRF, a different class of CSRF attack.
RT versions 3.6.1 and above are vulnerable to a remote execution of code vulnerability if the optional VERP configuration options ($VERPPrefix and $VERPDomain) are enabled. RT 3.8.0 and higher are vulnerable to a limited remote execution of code which can be leveraged for privilege escalation. RT 4.0.0 and above contain a vulnerability in the global $DisallowExecuteCode option, allowing sufficiently privileged users to still execute code even if RT was configured to not allow it. CVE-2011-4458 is assigned to this set of vulnerabilities.
RT versions 3.0 and above may, under some circumstances, still respect rights that a user only has by way of a currently-disabled group. CVE-2011-4459 is assigned to this vulnerability.
RT versions 2.0 and above are vulnerable to a SQL injection attack, which allow privileged users to obtain arbitrary information from the database. CVE-2011-4460 is assigned to this vulnerability.
Secunia team reports:
Multiple vulnerabilities have been reported in Sympa, which can be exploited by malicious people to bypass certain security restrictions.
The vulnerabilities are caused due to the application allowing access to archive functions without checking credentials. This can be exploited to create, download, and delete an archive.
Foswiki team reports:
When a new user registers, the new user can add arbitrary HTML and script code into the user topic which is generated by the RegistrationAgent via standard registration fields such as "FirstName" or "OrganisationName".
By design, Foswiki's normal editing features allow arbitrary HTML markup, including script code, to be inserted into any topic anyway, assuming the authenticated user has CHANGE permission - which is the case on many Foswiki sites. However, the assumption that only authenticated users with CHANGE permission may create script content is false if new users exploit the vulnerability detailed in this alert to manipulate the registration agent into creating that content for them.
Google chrome team reports:
An off-by-one out-of-bounds write flaw was found in the way libxml, a library for providing XML and HTML support, evaluated certain XPointer parts (XPointer is used by libxml to include only the part from the returned XML document, that can be accessed using the XPath expression given with the XPointer). A remote attacker could provide a specially-crafted XML file, which once opened in an application, linked against libxml, would lead to that application crash, or, potentially arbitrary code execution with the privileges of the user running the application.
Note: The flaw to be exploited requires the particular application, linked against libxml, to use the XPointer evaluation functionality.
InspIRCd reports:
InspIRCd contains a heap corruption vulnerability that exists in the dns.cpp code. The res[] buffer is allocated on the heap and can be overflowed. The res[] buffer can be exploited during its deallocation. The number of overflowed bytes can be controlled with DNS compression features.
The authors report:
Versions 3.2.0 and earlier of the pidgin-otr plugin contain a format string security flaw. This flaw could potentially be exploited by a remote attacker to cause arbitrary code to be executed on the user's machine.
The flaw is in pidgin-otr, not in libotr. Other applications that use libotr are not affected.
Todd Miller reports:
Sudo supports granting access to commands on a per-host basis. The host specification may be in the form of a host name, a netgroup, an IP address, or an IP network (an IP address with an associated netmask).
When IPv6 support was added to sudo, a bug was introduced that caused the IPv6 network matching code to be called when an IPv4 network address does not match. Depending on the value of the uninitialized portion of the IPv6 address, it is possible for the IPv4 network number to match when it should not. This bug only affects IP network matching and does not affect simple IP address matching.
The reported configuration that exhibited the bug was an LDAP-based sudo installation where the sudoRole object contained multiple sudoHost entries, each containing a different IPv4 network. File-based sudoers should be affected as well as the same matching code is used.
OpenSSL security team reports:
A flaw in the OpenSSL handling of CBC mode ciphersuites in TLS 1.1, 1.2 and DTLS can be exploited in a denial of service attack on both clients and servers.
The socat development team reports:
This vulnerability can be exploited when socat is invoked with the READLINE address (this is usually only used interactively) without option "prompt" and without option "noprompt" and an attacker succeeds to provide malicious data to the other (arbitrary) address that is then transferred by socat to the READLINE address for output.
Successful exploitation may allow an attacker to execute arbitrary code with the privileges of the socat process.
The PHP Development Team reports:
The release of PHP 5.4.13 and 5.4.3 complete a fix for the vulnerability in CGI-based setups as originally described in CVE-2012-1823. (CVE-2012-2311)
Note: mod_php and php-fpm are not vulnerable to this attack.
PHP 5.4.3 fixes a buffer overflow vulnerability in the apache_request_headers() (CVE-2012-2329).
Pidgin reports:
A series of specially crafted file transfer requests can cause clients to reference invalid memory. The user must have accepted one of the file transfer requests.
High-Tech Bridge reports:
Input passed via the "file" GET parameter to /pivotx/ajaxhelper.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in administrator's browser session in context of the affected website.
NVIDIA Unix security team reports:
Security vulnerability CVE-2012-0946 in the NVIDIA UNIX driver was disclosed to NVIDIA on March 20th, 2012. The vulnerability makes it possible for an attacker who has read and write access to the GPU device nodes to reconfigure GPUs to gain access to arbitrary system memory. NVIDIA is not aware of any reports of this vulnerability, outside of the disclosure which was made privately to NVIDIA.
NVIDIA has identified the root cause of the vulnerability and has released updated drivers which close it. [NVIDIA encourages] all users with Geforce 8 or newer, G80 Quadro or newer, and all Tesla GPUs to update their drivers to 295.40 or later.
Later, it was additionally discovered that similar exploit could be achieved through remapping of VGA window:
NVIDIA received notification of a security exploit that uses NVIDIA UNIX device files to map and program registers to redirect the VGA window. Through the VGA window, the exploit can access any region of physical system memory. This arbitrary memory access can be further exploited, for example, to escalate user privileges.
rubygem-mail -- multiple vulnerabilities
Two issues were fixed. They are a file system traversal in file_delivery method and arbitrary command execution when using exim or sendmail from the command line.
Private information disclosure
An attacker can cause private information disclosure.
Unsafe Temporary file creation
Config::IniFiles used a predictable name for its temporary file without opening it correctly.

php development team reports:
Security Enhancements for both PHP 5.3.11 and PHP 5.4.1:
- Insufficient validating of upload name leading to corrupted $_FILES indices. (CVE-2012-1172)
- Add open_basedir checks to readline_write_history and readline_read_history.
Security Enhancements for both PHP 5.3.11 only:
- Regression in magic_quotes_gpc fix for CVE-2012-0831.
The Samba project reports:
Samba versions 3.4.x to 3.6.4 inclusive are affected by a vulnerability that allows arbitrary users to modify privileges on a file server.
Security checks were incorrectly applied to the Local Security Authority (LSA) remote proceedure calls (RPC) CreateAccount, OpenAccount, AddAccountRights and RemoveAccountRights allowing any authenticated user to modify the privileges database.
This is a serious error, as it means that authenticated users can connect to the LSA and grant themselves the "take ownership" privilege. This privilege is used by the smbd file server to grant the ability to change ownership of a file or directory which means users could take ownership of files or directories they do not own.
Ports security team reports:
The portupgrade-devel port fetched directly from a git respository without checking against a known good SHA hash. This means that it is possible that packages built using this port may not match the one vetted by the maintainer. Users are advised to rebuild portupgrade-devel from known good sources.
The Red Hat Security Response Team reports:
An array index error, leading to out-of heap-based buffer read flaw was found in the way the net-snmp agent performed lookups in the extension table. When certain MIB subtrees were handled by the extend directive, a remote attacker (having read privileges to the subntree) could use this flaw to cause a denial of service condition via an SNMP GET request involving a non-existent extension table entry.

OpenSSL security team reports:
A potentially exploitable vulnerability has been discovered in the OpenSSL function asn1_d2i_read_bio. Any application which uses BIO or FILE based functions to read untrusted DER format data is vulnerable. Affected functions are of the form d2i_*_bio or d2i_*_fp, for example d2i_X509_bio or d2i_PKCS12_fp.
The following security issues have been discovered in Bugzilla:
Unauthorized Access
Due to a lack of proper validation of the X-FORWARDED-FOR header of an authentication request, an attacker could bypass the current lockout policy used for protection against brute- force password discovery. This vulnerability can only be exploited if the 'inbound_proxies' parameter is set.
Cross Site Scripting
A JavaScript template used by buglist.cgi could be used by a malicious script to permit an attacker to gain access to some information about bugs he would not normally be allowed to see, using the victim's credentials. To be exploitable, the victim must be logged in when visiting the attacker's malicious page.
All affected installations are encouraged to upgrade as soon as possible.
Typo Security Team reports:
Failing to properly encode the output, the default TYPO3 Exception Handler is susceptible to Cross-Site Scripting. We are not aware of a possibility to exploit this vulnerability without third party extensions being installed that put user input in exception messages. However, it has come to our attention that extensions using the extbase MVC framework can be used to exploit this vulnerability if these extensions accept objects in controller actions.

Samba development team reports:
Samba versions 3.6.3 and all versions previous to this are affected by a vulnerability that allows remote code execution as the "root" user from an anonymous connection.
As this does not require an authenticated connection it is the most serious vulnerability possible in a program, and users and vendors are encouraged to patch their Samba installations immediately.
A Bugzilla Security Advisory reports:
The following security issues have been discovered in Bugzilla:
- Due to a lack of validation of the enctype form attribute when making POST requests to xmlrpc.cgi, a possible CSRF vulnerability was discovered. If a user visits an HTML page with some malicious HTML code in it, an attacker could make changes to a remote Bugzilla installation on behalf of the victim's account by using the XML-RPC API on a site running mod_perl. Sites running under mod_cgi are not affected. Also, the user would have had to be already logged in to the target site for the vulnerability to work.
All affected installations are encouraged to upgrade as soon as possible.
Adobe reports:
Multiple Priority 2 vulnerabilities could cause a crash and potentially allow an attacker to take control of the affected system.
The PNG project reports:
libpng fails to correctly handle malloc() failures for text chunks (in png_set_text_2()), which can lead to memory corruption and the possibility of remote code execution.

The phpMyAdmin development team reports:
The show_config_errors.php scripts did not validate the presence of the configuration file, so an error message shows the full path of this file, leading to possible further attacks. For the error messages to be displayed, php.ini's error_reporting must be set to E_ALL and display_errors must be On (these settings are not recommended on a production server in the PHP manual).
Timothy D. Morgan reports:
In December 2011, VSR identified a vulnerability in multiple open source office products (including OpenOffice, LibreOffice, KOffice, and AbiWord) due to unsafe interpretation of XML files with custom entity declarations. Deeper analysis revealed that the vulnerability was caused by acceptance of external entities by the libraptor library, which is used by librdf and is in turn used by these office products.
In the context of office applications, these vulnerabilities could allow for XML External Entity (XXE) attacks resulting in file theft and a loss of user privacy when opening potentially malicious ODF documents. For other applications which depend on librdf or libraptor, potentially serious consequences could result from accepting RDF/XML content from untrusted sources, though the impact may vary widely depending on the context.
CERT reports:

The OpenSSL Team reports:
A weakness in the OpenSSL CMS and PKCS #7 code can be exploited using Bleichenbacher's attack on PKCS #1 v1.5 RSA padding also known as the million message attack (MMA).
Only users of CMS, PKCS #7, or S/MIME decryption operations are affected. A successful attack needs on average 2^20 messages. In practice only automated systems will be affected as humans will not be willing to process this many messages.
SSL/TLS applications are *NOT* affected by this problem since the SSL/TLS code does not use the PKCS#7 or CMS decryption code.

MFSA 2012-19 Miscellaneous memory safety hazards (rv:11.0/ rv:10.0.3 / rv:1.9.2.28)
Michael Gmelin and Jörg Scheinert has reported a remote command execution vulnerability in portaudit.
An attacker who can get the user to use a specially crafted audit file will be able to run commands on the users system, with the privileges of the user running running portaudit (often root).
The attack could e.g. happen through DNS hijacking or a man in the middle attack.
Note that if the user has set up portaudit to run from periodic this attack could happen without direct user interaction.
In the FreeBSD Ports Collection (bsd.port.mk) the check for vulnerable ports at install-time directly operates on the auditfile and has the same vulnerability as portaudit. As the Ports Collection infrastructure does not have a version number just be sure to have a Ports Collection new enough to contain the fix for portaudit. Note that this is only a problem for users which has portaudit installed, as they will not have the audit database installed or downloaded otherwise.
These vulnerabilities could cause a crash and potentially allow an attacker to take control of the affected system.
Jenkins Security Advisory reports:
An XSS vulnerability was found in Jenkins core, which allows an attacker to inject malicious HTMLs to pages served by Jenkins. This allows an attacker to escalate his privileges by hijacking sessions of other users. This vulnerability affects all versions.
The Dropbear project reports:
Dropbear SSH Server could allow a remote authenticated attacker to execute arbitrary code on the system, caused by a use-after- free error. If a command restriction is enforced, an attacker could exploit this vulnerability to execute arbitrary code on the system with root privileges.
OpenX does not provide information about vulnerabilities beyond their existence.
The PostgreSQL Global Development Group reports:
These vulnerabilities could allow users to define triggers that execute functions on which the user does not have EXECUTE permission, allow SSL certificate spoofing and allow line breaks in object names to be exploited to execute code when loading a pg_dump file.
These vulnerabilities could cause a crash and potentially allow an attacker to take control of the affected system.
Google chrome team reports:
Heap-based buffer overflow in libxml2, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.
Secunia reports:
A vulnerability has been discovered in PLIB, which can be exploited by malicious people to compromise an application using the library.
The vulnerability is caused due to a boundary error within the "ulSetError()" function (src/util/ulError.cxx) when creating the error message, which can be exploited to overflow a static buffer.
Successful exploitation allows the execution of arbitrary code but requires that the attacker can e.g. control the content of an overly long error message passed to the "ulSetError()" function.
The vulnerability is confirmed in version 1.8.5. Other versions may also be affected.
The phpMyAdmin development team reports:
It was possible to conduct XSS using a crafted database name.

Drupal development team reports:
Cross Site Request Forgery vulnerability in Aggregator module
CVE: CVE-2012-0826
An XSRF vulnerability can force an aggregator feed to update. Since some services are rate-limited (e.g. Twitter limits requests to 150 per hour) this could lead to a denial of service.
This issue affects Drupal 6.x and 7.x.
OpenID not verifying signed attributes in SREG and AX
CVE: CVE-2012-0825
A group of security researchers identified a flaw in how some OpenID relying parties implement Attribute Exchange (AX). Not verifying that attributes being passed through AX have been signed could allow an attacker to modify users' information.
This issue affects Drupal 6.x and 7.x.
Access bypass in File module
CVE: CVE-2012-0827
When using private files in combination with certain field access modules, the File module will allow users to download the file even if they do not have access to view the field it was attached to.
This issue affects Drupal 7.x only.
A Bugzilla Security Advisory reports:
The following security issues have been discovered in Bugzilla:
- Account Impersonation: When a user creates a new account, Bugzilla doesn't correctly reject email addresses containing non-ASCII characters, which could be used to impersonate another user account. Such email addresses could look visually identical to other valid email addresses, and an attacker could try to confuse other users and be added to bugs he shouldn't have access to.
- Cross-Site Request Forgery: Due to a lack of validation of the Content-Type head when making POST requests to jsonrpc.cgi, a possible CSRF vulnerability was discovered. If a user visits an HTML page with some malicious JS code in it, an attacker could make changes to a remote Bugzilla installation on behalf of the victim's account by using the JSON-RPC API. The user would have had to be already logged in to the target site for the vulnerability to work.
All affected installations are encouraged to upgrade as soon as possible.
Secunia reports:
A vulnerability has been reported in PHP, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a logic error within the "php_register_variable_ex()" function (php_variables.c) when hashing form posts and updating a hash table, which can be exploited to execute arbitrary code.

CVE MITRE reports:
An exposure was found when using mod_proxy in reverse proxy mode. In certain configurations using RewriteRule with proxy flag or ProxyPassMatch, a remote attacker could cause the reverse proxy to connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to attacker.
Integer overflow in the ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, allows local users to gain privileges via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, leading to a heap-based buffer overflow.
An additional exposure was found when using mod_proxy in reverse proxy mode. In certain configurations using RewriteRule with proxy flag or ProxyPassMatch, a remote attacker could cause the reverse proxy to connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to attacker.
A flaw was found in mod_log_config. If the '%{cookiename}C' log format string is in use, a remote attacker could send a specific cookie causing a crash. This crash would only be a denial of service if using a threaded MPM.
A flaw was found in the handling of the scoreboard. An unprivileged child process could cause the parent process to crash at shutdown rather than terminate cleanly.
A flaw was found in the default error response for status code 400. This flaw could be used by an attacker to expose "httpOnly" cookies when no custom ErrorDocument is specified.

Todd Miller reports:
Sudo 1.8.0 introduced simple debugging support that was primarily intended for use when developing policy or I/O logging plugins. The sudo_debug() function contains a flaw where the program name is used as part of the format string passed to the fprintf() function. The program name can be controlled by the caller, either via a symbolic link or, on some systems, by setting argv[0] when executing sudo.
Using standard format string vulnerability exploitation techniques it is possible to leverage this bug to achieve root privileges.
Exploitation of the bug does not require that the attacker be listed in the sudoers file. As such, we strongly suggest that affected sites upgrade from affected sudo versions as soon as possible.
Problem Description:
Some third-party applications, including KDE's kcheckpass command, allow the user to specify the name of the policy on the command line. Since OpenPAM treats the policy name as a path relative to /etc/pam.d or /usr/local/etc/pam.d, users who are permitted to run such an application can craft their own policies and cause the application to load and execute their own modules.
Problem Description:
The OpenSSL library call used to decrypt private keys ignores the passphrase argument if the key is not encrypted. Because the pam_ssh module only checks whether the passphrase provided by the user is null, users with unencrypted SSH private keys may successfully authenticate themselves by providing a dummy passphrase.
Problem Description:
When a UNIX-domain socket is attached to a location using the bind(2) system call, the length of the provided path is not validated. Later, when this address was returned via other system calls, it is copied into a fixed-length buffer.
Linux uses a larger socket address structure for UNIX-domain sockets than FreeBSD, and the FreeBSD's linux emulation code did not translate UNIX-domain socket addresses into the correct size of structure.
Problem Description:
The code used to decompress a file created by compress(1) does not do sufficient boundary checks on compressed code words, allowing reference beyond the decompression table, which may result in a stack overflow or an infinite loop when the decompressor encounters a corrupted file.
Problem Description:
While parsing the exports(5) table, a network mask in the form of "-network=netname/prefixlength" results in an incorrect network mask being computed if the prefix length is not a multiple of 8.
For example, specifying the ACL for an export as "-network 192.0.2.0/23" would result in a netmask of 255.255.127.0 being used instead of the correct netmask of 255.255.254.0.

Secunia reports:
Fixed a number of very serious errors in the usage of snprintf()/vsnprintf().
The return value was being used as the length of the string printed into the buffer, but the return value really indicates the length of the string that *could* be printed if the buffer were of infinite size. Because the returned value could be larger than the buffer's size, this meant remotely exploitable buffer overflows were possible, depending on spamdyke's configuration.
The OpenSSL Team reports:
A flaw in the fix to CVE-2011-4108 can be exploited in a denial of service attack. Only DTLS applications using OpenSSL 1.0.0f and 0.9.8s are affected.
Asterisk project reports:

The Tomcat security team reports:
Analysis of the recent hash collision vulnerability identified unrelated inefficiencies with Apache Tomcat's handling of large numbers of parameters and parameter values. These inefficiencies could allow an attacker, via a specially crafted request, to cause large amounts of CPU to be used which in turn could create a denial of service. The issue was addressed by modifying the Tomcat parameter handling code to efficiently process large numbers of parameters and parameter values.
The OpenTTD Team reports:
Using a slow read type attack it is possible to prevent anyone from joining a server with virtually no resources. Once downloading the map no other downloads of the map can start, so downloading really slowly will prevent others from joining. This can be further aggravated by the pause-on-join setting in which case the game is paused and the players cannot continue the game during such an attack. This attack requires that the user is not banned and passes the authorization to the server, although for many servers there is no server password and thus authorization is easy.
oCERT reports:
A variety of programming languages suffer from a denial-of-service (DoS) condition against storage functions of key/value pairs in hash data structures, the condition can be leveraged by exploiting predictable collisions in the underlying hashing algorithms.
The issue finds particular exposure in web server applications and/or frameworks. In particular, the lack of sufficient limits for the number of parameters in POST requests in conjunction with the predictable collision properties in the hashing functions of the underlying languages can render web applications vulnerable to the DoS condition. The attacker, using specially crafted HTTP requests, can lead to a 100% of CPU usage which can last up to several hours depending on the targeted application and server performance, the amplification effect is considerable and requires little bandwidth and time on the attacker side.
The condition for predictable collisions in the hashing functions has been reported for the following language implementations: Java, JRuby, PHP, Python, Rubinius, Ruby. In the case of the Ruby language, the 1.9.x branch is not affected by the predictable collision condition since this version includes a randomization of the hashing function.
The vulnerability outlined in this advisory is practically identical to the one reported in 2003 and described in the paper Denial of Service via Algorithmic Complexity Attacks which affected the Perl language.
Ubuntu Security Notice USN-1320-1 reports:
Phillip Langlois discovered that FFmpeg incorrectly handled certain malformed QDM2 streams. If a user were tricked into opening a crafted QDM2 stream file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2011-4351)
Phillip Langlois discovered that FFmpeg incorrectly handled certain malformed VP3 streams. If a user were tricked into opening a crafted file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2011-4352)
Phillip Langlois discovered that FFmpeg incorrectly handled certain malformed VP5 and VP6 streams. If a user were tricked into opening a crafted file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2011-4353)
It was discovered that FFmpeg incorrectly handled certain malformed VMD files. If a user were tricked into opening a crafted VMD file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2011-4364)
Phillip Langlois discovered that FFmpeg incorrectly handled certain malformed SVQ1 streams. If a user were tricked into opening a crafted SVQ1 stream file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2011-4579)
The OpenSSL Team reports:
6 security flaws have been fixed in OpenSSL 1.0.0f:
If X509_V_FLAG_POLICY_CHECK is set in OpenSSL 0.9.8, then a policy check failure can lead to a double-free.
OpenSSL prior to 1.0.0f and 0.9.8s failed to clear the bytes used as block cipher padding in SSL 3.0 records. As a result, in each record, up to 15 bytes of uninitialized memory may be sent, encrypted, to the SSL peer. This could include sensitive contents of previously freed memory.
RFC 3779 data can be included in certificates, and if it is malformed, may trigger an assertion failure. This could be used in a denial-of-service attack.
Support for handshake restarts for server gated cryptograpy (SGC) can be used in a denial-of-service attack.
A malicious TLS client can send an invalid set of GOST parameters which will cause the server to crash due to lack of error checking. This could be used in a denial-of-service attack.
ISC reports:
Due to improper handling of a DHCPv6 lease structure, ISC DHCP servers that are serving IPv6 address pools AND using Dynamic DNS can encounter a segmentation fault error while updating lease status under certain conditions.
The potential exists for this condition to be intentionally triggered, resulting in effective denial of service to clients expecting service from the affected server.
The PowerDNS Team reports:
Using well crafted UDP packets, one or more PowerDNS servers could be made to enter a tight packet loop, causing temporary denial of service.
php development team reports:
Security Enhancements and Fixes in PHP 5.3.9:
- Added max_input_vars directive to prevent attacks based on hash collisions. (CVE-2011-4885)
- Fixed bug #60150 (Integer overflow during the parsing of invalid exif header). (CVE-2011-4566)
TORCS News reports:
An insecure change to LD_LIBRARY_PATH allows loading of libraries in directories other than the standard paths. This can be a problem when downloading and installing untrusted content from the Internet.
Secunia reports:
The vulnerability is caused due to the TLS implementation not properly clearing transport layer buffers when upgrading from plaintext to ciphertext after receiving the "STARTTLS" command. This can be exploited to insert arbitrary plaintext data (e.g. SMTP commands) during the plaintext phase, which will then be executed after upgrading to the TLS ciphertext phase.
A Bugzilla Security Advisory reports:
The following security issues have been discovered in Bugzilla:
- Tabular and graphical reports, as well as new charts have a debug mode which displays raw data as plain text. This text is not correctly escaped and a crafted URL could use this vulnerability to inject code leading to XSS.
- The User.offer_account_by_email WebService method ignores the user_can_create_account setting of the authentication method and generates an email with a token in it which the user can use to create an account. Depending on the authentication method being active, this could allow the user to log in using this account. Installations where the createemailregexp parameter is empty are not vulnerable to this issue.
- The creation of bug reports and of attachments is not protected by a token and so they can be created without the consent of a user if the relevant code is embedded in an HTML page and the user visits this page. This behavior was intentional to let third-party applications submit new bug reports and attachments easily. But as this behavior can be abused by a malicious user, it has been decided to block submissions with no valid token starting from version 4.2rc1. Older branches are not patched to not break these third-party applications after the upgrade.
All affected installations are encouraged to upgrade as soon as possible.
WordPress development team reports:
WordPress 3.3.1 is now available. This maintenance release fixes 15 issues with WordPress 3.3, as well as a fix for a cross-site scripting vulnerability that affected version 3.3. Thanks to Joshua H., Hoang T., Stefan Zimmerman, Chris K., and the Go Daddy security team for responsibly disclosing the bug to our security team.
Martina Matari reports:
These URLs (hostgroups.php, usergrps.php) are vulnerable to persistent XSS attacks due to improper sanitation of gname variable when creating user and host groups.
US-CERT/NIST reports:
Integer signedness error in the base64_decode function in the HTTP authentication functionality (http_auth.c) in lighttpd 1.4 before 1.4.30 and 1.5 before SVN revision 2806 allows remote attackers to cause a denial of service (segmentation fault) via crafted base64 input that triggers an out-of-bounds read with a negative index.
The MIT Kerberos Team reports:
When an encryption key is supplied via the TELNET protocol, its length is not validated before the key is copied into a fixed-size buffer. Also see MITKRB5-SA-2011-008.
The FreeBSD security advisory FreeBSD-SA-11:07.chroot reports:
If ftpd is configured to place a user in a chroot environment, then an attacker who can log in as that user may be able to run arbitrary code(...).
Proftpd shares the same problem of a similar nature.
The phpMyAdmin development team reports:
Using crafted url parameters, it was possible to produce XSS on the export panels in the server, database and table sections.
Crafted values entered in the setup interface can produce XSS; also, if the config directory exists and is writeable, the XSS payload can be saved to this directory.
The Mozilla Project reports:
MFSA 2011-53 Miscellaneous memory safety hazards (rv:9.0)
MFSA 2011-54 Potentially exploitable crash in the YARR regular expression library
MFSA 2011-55 nsSVGValue out-of-bounds access
MFSA 2011-56 Key detection without JavaScript via SVG animation
MFSA 2011-58 Crash scaling video to extreme sizes
Unbound developer reports:
Unbound crashes when confronted with a non-standard response from a server for a domain. This domain produces duplicate RRs from a certain type and is DNSSEC signed. Unbound also crashes when confronted with a query that eventually, and under specific circumstances, resolves to a domain that misses expected NSEC3 records.
The typo3 security team reports:
A crafted request to a vulnerable TYPO3 installation will allow an attacker to load PHP code from an external source and to execute it on the TYPO3 installation.
This is caused by a PHP file, which is part of the workspaces system extension, that does not validate passed arguments.
The MIT Kerberos Team reports:
In releases krb5-1.9 and later, the KDC can crash due to a NULL pointer dereference in code that handles TGS (Ticket Granting Service) requests. The trigger condition is trivial to produce using unmodified client software, but requires the ability to authenticate as a principal in the KDC's realm.
Opera software reports:
- Fixed a moderately severe issue; details will be disclosed at a later date
- Fixed an issue that could allow pages to set cookies or communicate cross-site for some top level domains; see our advisory
- Improved handling of certificate revocation corner cases
- Added a fix for a weakness in the SSL v3.0 and TLS 1.0 specifications, as reported by Thai Duong and Juliano Rizzo; see our advisory
- Fixed an issue where the JavaScript "in" operator allowed leakage of cross-domain information, as reported by David Bloom; see our advisory
Simon Tatham reports:
PuTTY 0.62 fixes a security issue present in 0.59, 0.60 and 0.61. If you log in using SSH-2 keyboard-interactive authentication (which is the usual method used by modern servers to request a password), the password you type was accidentally kept in PuTTY's memory for the rest of its run, where it could be retrieved by other processes reading PuTTY's memory, or written out to swap files or crash dumps.
Asterisk project reports:
It is possible to enumerate SIP usernames when the general and user/peer NAT settings differ in whether to respond to the port a request is sent from or the port listed for responses in the Via header.
When the "automon" feature is enabled in features.conf, it is possible to send a sequence of SIP requests that cause Asterisk to dereference a NULL pointer and crash.
ISC reports:
A bug exists which allows an attacker who is able to send DHCP Request packets, either directly or through a relay, to remotely crash an ISC DHCP server if that server is configured to evaluate expressions using a regular expression (i.e. uses the "~=" or "~~" comparison operators).
The phpMyAdmin development team reports:
Using crafted database names, it was possible to produce XSS in the Database Synchronize and Database rename panels. Using an invalid and crafted SQL query, it was possible to produce XSS when editing a query on a table overview panel or when using the view creation dialog. Using a crafted column type, it was possible to produce XSS in the table search and create index dialogs.
Hugo Leisink reports via private mail to maintainer:
The memory leak was introduced in version 7.6. It is in the routing that checks for SQL injections. So, if you have set PreventSQLi to 'no', there is no problem.
The Internet Systems Consortium reports:
Organizations across the Internet reported crashes interrupting service on BIND 9 nameservers performing recursive queries. Affected servers crashed after logging an error in query.c with the following message: "INSIST(! dns_rdataset_isassociated(sigrdataset))" Multiple versions were reported being affected, including all currently supported release versions of ISC BIND 9.
Because it may be possible to trigger this bug even on networks that do not allow untrusted users to access the recursive name servers (perhaps via specially crafted e-mail messages, and/or malicious web sites) it is recommended that ALL operators of recursive name servers upgrade immediately.
Apache HTTP server project reports:
An exposure was found when using mod_proxy in reverse proxy mode. In certain configurations using RewriteRule with proxy flag, a remote attacker could cause the reverse proxy to connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to attacker. There is no patch against this issue!
Tim Brown from Nth Dimention reports:
I recently discovered that the Ark archiving tool is vulnerable to directory traversal via malformed. When attempts are made to view files within the malformed Zip file in Ark's default view, the wrong file may be displayed due to incorrect construction of the temporary file name. Whilst this does not allow the wrong file to be overwritten, after closing the default view, Ark will then attempt to delete the temporary file which could result in the deletion of the incorrect file.
The Apache Portable Runtime Project reports:
Reimplement apr_fnmatch() from scratch using a non-recursive algorithm; now has improved compliance with the fnmatch() spec.
Jan Lieskovsky reports:
Importing a specially-crafted XML file which contains an XML entity injection permits to retrieve a local file (limited by the privileges of the user running the web server).
Adobe Product Security Incident Response Team reports:
Critical vulnerabilities have been identified in Adobe Flash Player 11.0.1.152 and earlier versions for Windows, Macintosh, Linux and Solaris, and Adobe Flash Player 11.0.1.153 and earlier versions for Android.

The phpMyFAQ project reports:
The phpMyFAQ Team has learned of a serious security issue that has been discovered in our bundled ImageManager library we use in phpMyFAQ 2.6 and 2.7. The bundled ImageManager library allows injection of arbitrary PHP code via POST requests.
EgiX (n0b0d13s at gmail dot com) reports:
The $sortby parameter passed to 'masort' function in file lib/functions.php isn't properly sanitized before being used in a call to create_function() at line 1080. This can be exploited to inject and execute arbitrary PHP code. The only possible attack vector is when handling the 'query_engine' command, in which input passed through $_REQUEST['orderby'] is passed as $sortby parameter to 'masort' function.
KDE Security Advisory reports:
The default rendering type for a QLabel is QLabel::AutoText, which uses heuristics to determine whether to render the given content as plain text or rich text. KSSL and Rekonq did not properly force its QLabels to use QLabel::PlainText. As a result, if given a certificate containing rich text in its fields, they would render the rich text. Specifically, a certificate containing a common name (CN) that has a table element will cause the second line of the table to be displayed. This can allow spoofing of the certificate's common name.
Secunia reports:
Multiple vulnerabilities with an unknown impact have been reported in Piwik. The vulnerabilities are caused due to unspecified errors. No further information is currently available.
Matthieu Herrb reports:
It is possible to deduce if a file exists or not by exploiting the way that Xorg creates its lock files. This is caused by the fact that the X server is behaving differently if the lock file already exists as a symbolic link pointing to an existing or non-existing file.
It is possible for a non-root user to set the permissions for all users on any file or directory to 444, giving unwanted read access or causing denies of service (by removing execute permission). This is caused by a race between creating the lock file and setting its access modes.
Asterisk project reports:
A remote authenticated user can cause a crash with a malformed request due to an unitialized variable.
The PivotX team reports:
TimThumb domain name security bypass and insecure cache handling. PivotX before 2.3.0 includes a vulnerable version of TimThumb.
If you are still running PivotX 2.2.6, you might be vulnerable to a security exploit, that was patched previously. Version 2.3.0 doesn't have this issue, but any older version of PivotX might be vulnerable.
The OpenTTD Team reports:
Multiple buffer overflows in OpenTTD before 1.1.3 allow local users to cause a denial of service (daemon crash) or possibly gain privileges via (1) a crafted BMP file with RLE compression or (2) crafted dimensions in a BMP file.
The OpenTTD Team reports:
Multiple buffer overflows in OpenTTD before 1.1.3 allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors related to (1) NAME, (2) PLYR, (3) CHTS, or (4) AIPL (aka AI config) chunk loading from a savegame.
The OpenTTD Team reports:
Multiple off-by-one errors in order_cmd.cpp in OpenTTD before 1.1.3 allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted CMD_INSERT_ORDER command.
CERT-FI reports:
Five vulnerabilities have been found in the BGP, OSPF, and OSPFv3 components of Quagga. The vulnerabilities allow an attacker to cause a denial of service or potentially to execute his own code by sending a specially modified packets to an affected server. Routing messages are typically accepted from the routing peers. Exploiting these vulnerabilities may require an established routing session (BGP peering or OSPF/OSPFv3 adjacency) to the router.
The vulnerability CVE-2011-3327 is related to the extended communities handling in BGP messages. Receiving a malformed BGP update can result in a buffer overflow and disruption of IPv4 routing.
The vulnerability CVE-2011-3326 results from the handling of LSA (Link State Advertisement) states in the OSPF service. Receiving a modified Link State Update message with malicious state information can result in denial of service in IPv4 routing.
The vulnerability CVE-2011-3325 is a denial of service vulnerability related to Hello message handling by the OSPF service. As Hello messages are used to initiate adjacencies, exploiting the vulnerability may be feasible from the same broadcast domain without an established adjacency. A malformed packet may result in denial of service in IPv4 routing.
The vulnerabilities CVE-2011-3324 and CVE-2011-3323 are related to the IPv6 routing protocol (OSPFv3) implemented in ospf6d daemon. Receiving modified Database Description and Link State Update messages, respectively, can result in denial of service in IPv6 routing.

Secunia reports:
Hossein Lotfi has discovered a vulnerability in libsndfile, which can be exploited by malicious people to potentially compromise an application using the library. The vulnerability is caused due to an integer overflow error in the "paf24_init()" function (src/paf.c) when processing Paris Audio (PAF) files. This can be exploited to cause a heap-based buffer overflow via a specially crafted file. Successful exploitation may allow execution of arbitrary code. The vulnerability is confirmed in version 1.0.24. Other versions may also be affected.
OpenSSL Team reports:
Two security flaws have been fixed in OpenSSL 1.0.0e
Under certain circumstances OpenSSL's internal certificate verification routines can incorrectly accept a CRL whose nextUpdate field is in the past. (CVE-2011-3207)
OpenSSL server code for ephemeral ECDH ciphersuites is not thread-safe, and furthermore can crash if a client violates the protocol by sending handshake messages in incorrect order. (CVE-2011-3210)
Net.Edit0r from BlACK Hat Group reported an XSS issue in search.php. All MantisBT users (including anonymous users that are not logged in to public bug trackers) could be impacted by this vulnerability.
Debian reports:
Zorgon found several buffer overflows in cfsd, a daemon that pushes encryption services into the Unix(tm) file system. We are not yet sure if these overflows can successfully be exploited to gain root access to the machine running the CFS daemon. However, since cfsd can easily be forced to die, a malicious user can easily perform a denial of service attack to it.
Matthias Andree reports that the ca-bundle.pl used in older versions of the ca_root_nss FreeBSD port before 3.12.11 did not take the Mozilla/NSS/CKBI untrusted markers into account and would add certificates to the trust bundle that were marked unsafe by Mozilla.
Heather Adkins, Google's Information Security Manager, reported that Google received
[...] reports of attempted SSL man-in-the-middle (MITM) attacks against Google users, whereby someone tried to get between them and encrypted Google services. The people affected were primarily located in Iran. The attacker used a fraudulent SSL certificate issued by DigiNotar, a root certificate authority that should not issue certificates for Google (and has since revoked it). [...]
VASCO Data Security International Inc., owner of DigiNotar, issued a press statement confirming this incident:
On July 19th 2011, DigiNotar detected an intrusion into its Certificate Authority (CA) infrastructure, which resulted in the fraudulent issuance of public key certificate requests for a number of domains, including Google.com. [...] an external security audit concluded that all fraudulently issued certificates were revoked. Recently, it was discovered that at least one fraudulent certificate had not been revoked at the time. [...]
Mozilla, maintainer of the NSS package, from which FreeBSD derived ca_root_nss, stated that they:
revoked our trust in the DigiNotar certificate authority from all Mozilla software. This is not a temporary suspension, it is a complete removal from our trusted root program. Complete revocation of trust is a decision we treat with careful consideration, and employ as a last resort.
Three central issues informed our decision:
- Failure to notify. [...]
- The scope of the breach remains unknown. [...]
- The attack is not theoretical.

ISC reports:
A pair of defects cause the server to halt upon processing certain packets. The patch is to properly discard or process those packets.
A Bugzilla Security Advisory reports:
The following security issues have been discovered in Bugzilla:
- Internet Explorer 8 and older, and Safari before 5.0.6 do content sniffing when viewing a patch in "Raw Unified" mode, which could trigger a cross-site scripting attack due to the execution of malicious code in the attachment.
- It is possible to determine whether or not certain group names exist while creating or updating bugs.
- Attachment descriptions with a newline in them could lead to the injection of crafted headers in email notifications sent to the requestee or the requester when editing an attachment flag.
- If an attacker has access to a user's session, he can modify that user's email address without that user being notified of the change.
- Temporary files for uploaded attachments are not deleted on Windows, which could let a user with local access to the server read them.
- Up to Bugzilla 3.4.11, if a BUGLIST cookie is compromised, it can be used to inject HTML code when viewing a bug report, leading to a cross-site scripting attack.
All affected installations are encouraged to upgrade as soon as possible.
Ansgar Burchardt reports:
Ansgar Burchardt discovered several vulnerabilities in DTC, a web control panel for admin and accounting hosting services: The bw_per_moth.php graph contains an SQL injection vulnerability; insufficient checks in bw_per_month.php can lead to bandwidth usage information disclosure; after a registration, passwords are sent in cleartext email messages and Authenticated users could delete accounts using an obsolete interface which was incorrectly included in the package.
Tomas Hoger reports:
The compress/ LZW decompress implentation does not correctly handle compressed streams that contain code words that were not yet added to the decompression table. This may lead to arbitrary memory corruption. Successfull exploitation may possible lead to a local privilege escalation.
Vincent Danen reports:
Due to an error within the t1_decoder_parse_charstrings() function (src/psaux/t1decode.c) and can be exploited to corrupt memory by tricking a user into processing a specially-crafted postscript Type1 font in an application that uses the freetype library.
Adobe Product Security Incident Response Team reports:
Critical vulnerabilities have been identified in Adobe Flash Player 10.3.181.36 and earlier versions for Windows, Macintosh, Linux and Solaris, and Adobe Flash Player 10.3.185.25 and earlier versions for Android. These vulnerabilities could cause a crash and potentially allow an attacker to take control of the affected system.
Dan Winship reports:
Fixed a security hole that caused some SoupServer users to unintentionally allow accessing the entire local filesystem when they thought they were only providing access to a single directory.
The phpMyAdmin development team reports:
XSS in table Print view.
Via a crafted MIME-type transformation parameter, an attacker can perform a local file inclusion.
In the 'relational schema' code a parameter was not sanitized before being used to concatenate a class name.
The end result is a local file inclusion vulnerability and code execution.
It was possible to manipulate the PHP session superglobal using some of the Swekey authentication code.
This is very similar to PMASA-2011-5, documented in 7e4e5c53-a56c-11e0-b180-00216aa06fc2
OpenSAML developer reports:
The Shibboleth software relies on the OpenSAML libraries to perform verification of signed XML messages such as attribute queries or SAML assertions. Both the Java and C++ versions are vulnerable to a so-called "wrapping attack" that allows a remote, unauthenticated attacker to craft specially formed messages that can be successfully verified, but contain arbitrary content.
rsync development team reports:
Fixed a data-corruption issue when preserving hard-links without preserving file ownership, and doing deletions either before or during the transfer (CVE-2011-1097). This fixes some assert errors in the hard-linking code, and some potential failed checksums (via -c) that should have matched.
ISC reports:
A defect in the affected BIND 9 versions allows an attacker to remotely cause the "named" process to exit using a specially crafted packet.
This defect affects both recursive and authoritative servers.
ISC reports:
Two defects were discovered in ISC's BIND 9.8 code. These defects only affect BIND 9.8 servers which have recursion enabled and which use a specific feature of the software known as Response Policy Zones (RPZ) and where the RPZ zone contains a specific rule/action pattern.
The phpMyAdmin development team reports:
It was possible to manipulate the PHP session superglobal using some of the Swekey authentication code. This could open a path for other attacks.
An unsanitized key from the Servers array is written in a comment of the generated config. An attacker can modify this key by modifying the SESSION superglobal array. This allows the attacker to close the comment and inject code.
Through a possible bug in PHP running on Windows systems a NULL byte can truncate the pattern string allowing an attacker to inject the /e modifier causing the preg_replace function to execute its second argument as PHP code.
Fixed filtering of a file path in the MIME-type transformation code, which allowed for directory traversal.
The Asterisk Development Team reports:
AST-2011-008: If a remote user sends a SIP packet containing a NULL, Asterisk assumes available data extends past the null to the end of the packet when the buffer is actually truncated when copied. This causes SIP header parsing to modify data past the end of the buffer altering unrelated memory structures. This vulnerability does not affect TCP/TLS connections.
AST-2011-009: A remote user sending a SIP packet containing a Contact header with a missing left angle bracket causes Asterisk to access a null pointer.
AST-2011-010: A memory address was inadvertently transmitted over the network via IAX2 via an option control frame and the remote party would try to access it.
Possible enumeration of SIP users due to differing authentication responses.
It's reported in CVE advisory that:
expat_erl.c in ejabberd before 2.1.7 and 3.x before 3.0.0-alpha-3, and exmpp before 0.9.7, does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.

The Samba team reports:
Samba is vulnerable to a denial of service, caused by a memory corruption error related to missing range checks on file descriptors being used in the "FD_SET" macro. By performing a select on a bad file descriptor set, a remote attacker could exploit this vulnerability to cause the application to crash or possibly execute arbitrary code on the system.
The Piwik security advisory reports:
The Piwik 1.5 release addresses a critical security vulnerability, which affect all Piwik users that have let granted some access to the "anonymous" user.
Piwik contains a remotely exploitable vulnerability that could allow a remote attacker to execute arbitrary code. Only installations that have granted untrusted view access to their stats (ie. grant "view" access to a website to anonymous) are at risk.
Dokuwiki reports:
We just released a Hotfix Release "2011-05-25a Rincewind". It contains the following changes:
Security fix for a Cross Site Scripting vulnerability. Malicious users could abuse DokuWiki's RSS embedding mechanism to create links containing arbitrary JavaScript. Note: this security problem is present in at least Anteater and Rincewind but probably in older releases as well.
Adobe Product Security Incident Response Team reports:
A critical vulnerability has been identified in Adobe Flash Player 10.3.181.23 and earlier versions for Windows, Macintosh, Linux and Solaris, and Adobe Flash Player 10.3.185.23 and earlier versions for Android. This memory corruption vulnerability (CVE-2011-2110) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being exploited in the wild in targeted attacks via malicious Web pages.
The IkiWiki development team reports:
Ludwig Nussel discovered a way for users to hijack root's tty when ikiwiki-mass-rebuild was run. Additionally, there was some potential for information disclosure via symlinks.
Adobe Product Security Incident Response Team reports:
An important vulnerability has been identified in Adobe Flash Player 10.3.181.16 and earlier versions for Windows, Macintosh, Linux and Solaris, and Adobe Flash Player 10.3.185.22 and earlier versions for Android. This universal cross-site scripting vulnerability (CVE-2011-2107) could be used to take actions on a user's behalf on any website or webmail provider, if the user visits a malicious website. There are reports that this vulnerability is being exploited in the wild in active targeted attacks designed to trick the user into clicking on a malicious link delivered in an email message.
ISC reports:
A BIND 9 DNS server set up to be a caching resolver is vulnerable to a user querying a domain with very large resource record sets (RRSets) when trying to negatively cache a response. This can cause the BIND 9 DNS server (named process) to crash.
Matthias Andree reports:
Fetchmail version 5.9.9 introduced STLS support for POP3, version 6.0.0 added STARTTLS for IMAP. However, the actual S(TART)TLS-initiated in-band SSL/TLS negotiation was not guarded by a timeout.
Depending on the operating system defaults as to TCP stream keepalive mode, fetchmail hangs in excess of one week after sending STARTTLS were observed if the connection failed without notifying the operating system, for instance, through network outages or hard server crashes.
A malicious server that does not respond, at the network level, after acknowledging fetchmail's STARTTLS or STLS request, can hold fetchmail in this protocol state, and thus render fetchmail unable to complete the poll, or proceed to the next server, effecting a denial of service.
SSL-wrapped mode on dedicated ports was unaffected by this problem, so can be used as a workaround.
The Asterisk Development Team reports:
If a remote user initiates a SIP call and the recipient picks up, the remote user can reply with a malformed Contact header that Asterisk will improperly handle and cause a crash due to a segmentation fault.
Subversion team reports:
Subversion's mod_dav_svn Apache HTTPD server module will dereference a NULL pointer if asked to deliver baselined WebDAV resources.
This can lead to a DoS. An exploit has been tested, and tools or users have been observed triggering this problem in the wild.
Subversion's mod_dav_svn Apache HTTPD server module may in certain scenarios enter a logic loop which does not exit and which allocates memory in each iteration, ultimately exhausting all the available memory on the server.
This can lead to a DoS. There are no known instances of this problem being observed in the wild, but an exploit has been tested.
Subversion's mod_dav_svn Apache HTTPD server module may leak to remote users the file contents of files configured to be unreadable by those users.
There are no known instances of this problem being observed in the wild, but an exploit has been tested.
Drupal Team reports:
A reflected cross site scripting vulnerability was discovered in Drupal's error handler. Drupal displays PHP errors in the messages area, and a specially crafted URL can cause malicious scripts to be injected into the message. The issue can be mitigated by disabling on-screen error display at admin / settings / error-reporting. This is the recommended setting for production sites.
When using re-colorable themes, color inputs are not sanitized. Malicious color values can be used to insert arbitrary CSS and script code. Successful exploitation requires the "Administer themes" permission.
US-CERT reports:
The Erlang/OTP ssh library implements a number of cryptographic operations that depend on cryptographically strong random numbers. Unfortunately the RNG used by the library is not cryptographically strong, and is further weakened by the use of predictable seed material. The RNG (Wichman-Hill) is not mixed with an entropy source.
Unbound developer reports:
NLnet Labs was notified of an error in Unbound's code-path for error replies which is triggered under special conditions. The error causes the program to abort.
Nathan Dors, Pubcookie Project reports:
A new non-persistent XSS vulnerability was found in the Pubcookie login server's compiled binary "index.cgi" CGI program. The CGI program mishandles untrusted data when printing responses to the browser. This makes the program vulnerable to carefully crafted requests containing script or HTML. If an attacker can lure an unsuspecting user to visit carefully staged content, the attacker can use it to redirect the user to his or her local Pubcookie login page and attempt to exploit the XSS vulnerability.
Nathan Dors, Pubcookie Project reports:
An Abuse of Functionality vulnerability in the Pubcookie authentication process was found. This vulnerability allows an attacker to appear as if he or she were authenticated using an empty userid when such a userid isn't expected. Unauthorized access to web content and applications may result where access is restricted to users who can authenticate successfully but where no additional authorization is performed after authentication.
ViewVC.org reports:
Security fix: remove user-reachable override of cvsdb row limit.
The Apache Portable Runtime Project reports:
A flaw was discovered in the apr_fnmatch() function in the Apache Portable Runtime (APR) library 1.4.4 (or any backported versions that contained the upstream fix for CVE-2011-0419). This could cause httpd workers to enter a hung state (100% CPU utilization).
apr-util 1.3.11 could cause crashes with httpd's mod_authnz_ldap in some situations.
Adobe Product Security Incident Response Team reports:
Critical vulnerabilities have been identified in Adobe Flash Player 10.2.159.1 and earlier versions (Adobe Flash Player 10.2.154.28 and earlier for Chrome users) for Windows, Macintosh, Linux and Solaris, and Adobe Flash Player 10.2.157.51 and earlier versions for Android. These vulnerabilities could cause the application to crash and could potentially allow an attacker to take control of the affected system. There are reports of malware attempting to exploit one of the vulnerabilities, CVE-2011-0627, in the wild via a Flash (.swf) file embedded in a Microsoft Word (.doc) or Microsoft Excel (.xls) file delivered as an email attachment targeting the Windows platform. However, to date, Adobe has not obtained a sample that successfully completes an attack.
Opera Software ASA reports:
Fixed an issue with framesets that could allow execution of arbitrary code, as reported by an anonymous contributor working with the SecuriTeam Secure Disclosure program.
Pure-FTPd development team reports:
Support for braces expansion in directory listings has been disabled -- Cf. CVE-2011-0418.
Fix a STARTTLS flaw similar to Postfix's CVE-2011-0411. If you're using TLS, upgrading is recommended.
Release notes for Exim 4.76 says:
Bugzilla 1106: CVE-2011-1764 - DKIM log line was subject to a format-string attack -- SECURITY: remote arbitrary code execution.
DKIM signature header parsing was double-expanded, second time unintentionally subject to list matching rules, letting the header cause arbitrary Exim lookups (of items which can occur in lists, *not* arbitrary string expansion). This allowed for information disclosure.
Also, impact assessment was redone shortly after the original announcement:
Further analysis revealed that the second security was more severe than I realised at the time that I wrote the announcement. The second security issue has been assigned CVE-2011-1407 and is also a remote code execution flaw. For clarity: both issues were introduced with 4.70.
The Apache Portable Runtime Project reports:
Note especially a security fix to APR 1.4.4, excessive CPU consumption was possible due to an unconstrained, recursive invocation of apr_fnmatch, as apr_fnmatch processed '*' wildcards. Reimplement apr_fnmatch() from scratch using a non-recursive algorithm now has improved compliance with the fnmatch() spec. (William Rowe)
The Zend Framework team reports:
Developers using non-ASCII-compatible encodings in conjunction with the MySQL PDO driver of PHP may be vulnerable to SQL injection attacks. Developers using ASCII-compatible encodings like UTF8 or latin1 are not affected by this PHP issue.
Mediawiki reports:
(Bug 28534) XSS vulnerability for IE 6 clients. This is the third attempt at fixing bug 28235.
(Bug 28639) Potential privilege escalation when $wgBlockDisablesLogin is enabled.
The Postfix SMTP server has a memory corruption error, when the Cyrus SASL library is used with authentication mechanisms other than PLAIN and LOGIN (ANONYMOUS is not affected, but should not be used for other reasons). This memory corruption is known to result in a program crash (SIGSEV).

The Asterisk Development Team reports:
It is possible for a user of the Asterisk Manager Interface to bypass a security check and execute shell commands when they should not have that ability. Sending the "Async" header with the "Application" header during an Originate action, allows authenticated manager users to execute shell commands. Only users with the "system" privilege should be able to do this.
On systems that have the Asterisk Manager Interface, Skinny, SIP over TCP, or the built in HTTP server enabled, it is possible for an attacker to open as many connections to asterisk as he wishes. This will cause Asterisk to run out of available file descriptors and stop processing any new calls. Additionally, disk space can be exhausted as Asterisk logs failures to open new file descriptors.
VideoLAN project reports:
When parsing some MP4 (MPEG-4 Part 14) files, insufficient buffer size might lead to corruption of the heap.
Adobe Product Security Incident Response Team reports:
A critical vulnerability exists in Flash Player 10.2.153.1 and earlier versions (Adobe Flash Player 10.2.154.25 and earlier for Chrome users) for Windows, Macintosh, Linux and Solaris, Adobe Flash Player 10.2.156.12 and earlier versions for Android, and the Authplay.dll component that ships with Adobe Reader and Acrobat X (10.0.2) and earlier 10.x and 9.x versions for Windows and Macintosh operating systems.
This vulnerability (CVE-2011-0611) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being exploited in the wild in targeted attacks via a malicious Web page or a Flash (.swf) file embedded in a Microsoft Word (.doc) or Microsoft Excel (.xls) file delivered as an email attachment, targeting the Windows platform. At this time, Adobe is not aware of any attacks via PDF targeting Adobe Reader and Acrobat. Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing.
Best Practical reports:
In the process of preparing the release of RT 4.0.0, we performed an extensive security audit of RT's source code. During this audit, several vulnerabilities were found which affect earlier releases of RT.
An advisory published by the MIT Kerberos team says:
The password-changing capability of the MIT krb5 administration daemon (kadmind) has a bug that can cause it to attempt to free() an invalid pointer under certain error conditions. This can cause the daemon to crash or induce the execution of arbitrary code (which is believed to be difficult). No exploit that executes arbitrary code is known to exist, but it is easy to trigger a denial of service manually.
Some platforms detect attempted freeing of invalid pointers and protectively terminate the process, preventing arbitrary code execution on those platforms.
An advisory published by the MIT Kerberos team says:
The MIT Kerberos 5 Key Distribution Center (KDC) daemon is vulnerable to a double-free condition if the Public Key Cryptography for Initial Authentication (PKINIT) capability is enabled, resulting in daemon crash or arbitrary code execution (which is believed to be difficult).
An unauthenticated remote attacker can induce a double-free event, causing the KDC daemon to crash (denial of service), or to execute arbitrary code. Exploiting a double-free event to execute arbitrary code is believed to be difficult.
An advisory published by the MIT Kerberos team says:
The MIT krb5 Key Distribution Center (KDC) daemon is vulnerable to denial of service attacks from unauthenticated remote attackers. CVE-2011-0281 and CVE-2011-0282 occur only in KDCs using LDAP back ends, but CVE-2011-0283 occurs in all krb5-1.9 KDCs.
Exploit code is not known to exist, but the vulnerabilities are easy to trigger manually. The trigger for CVE-2011-0281 has already been disclosed publicly, but that fact might not be obvious to casual readers of the message in which it was disclosed. The triggers for CVE-2011-0282 and CVE-2011-0283 have not yet been disclosed publicly, but they are also trivial.
CVE-2011-0281: An unauthenticated remote attacker can cause a KDC configured with an LDAP back end to become completely unresponsive until restarted.
CVE-2011-0282: An unauthenticated remote attacker can cause a KDC configured with an LDAP back end to crash with a null pointer dereference.
CVE-2011-0283: An unauthenticated remote attacker can cause a krb5-1.9 KDC with any back end to crash with a null pointer dereference.
An advisory published by the MIT Kerberos team says:
The MIT krb5 KDC database propagation daemon (kpropd) is vulnerable to a denial-of-service attack triggered by invalid network input. If a kpropd worker process receives invalid input that causes it to exit with an abnormal status, it can cause the termination of the listening process that spawned it, preventing the slave KDC it was running on from receiving database updates from the master KDC.
Exploit code is not known to exist, but the vulnerabilities are easy to trigger manually.
An unauthenticated remote attacker can cause kpropd running in standalone mode (the "-S" option) to terminate its listening process, preventing database propagations to the KDC host on which it was running. Configurations where kpropd runs in incremental propagation mode ("iprop") or as an inetd server are not affected.
Matthias Hopf reports:
By crafting hostnames with shell escape characters, arbitrary commands can be executed in a root environment when a display manager reads in the resource database via xrdb.
These specially crafted hostnames can occur in two environments:
Systems are affected are: systems set their hostname via DHCP, and the used DHCP client allows setting of hostnames with illegal characters. And systems that allow remote logins via xdmcp.
OTRS Security Advisory reports:
- Several XSS attacks possible: An attacker could trick a logged in user to following a prepared URL inside of the OTRS system which causes a page to be shown that possibly includes malicious !JavaScript code because of incorrect escaping during the generation of the HTML page.
ISC reports:
ISC dhclient did not strip or escape certain shell meta-characters in responses from the dhcp server (like hostname) before passing the responses on to dhclient-script. Depending on the script and OS, this can result in execution of exploit code on the client.
When including a line to allow a network of IP addresses, the access to tinyproxy 56 is actually allowed for all IP addresses.
Quagga developers report:
Quagga 0.99.18 has been released. This release fixes 2 denial of services in bgpd, which can be remotely triggered by malformed AS-Pathlimit or Extended-Community attributes. These issues have been assigned CVE-2010-1674 and CVE-2010-1675. Support for AS-Pathlimit has been removed with this release.
Sebastian Krahmer reports:
It was discovered that the GNOME Display Manager (gdm) cleared the cache directory, which is owned by an unprivileged user, with the privileges of the root user. A race condition exists in gdm where a local user could take advantage of this by writing to the cache directory between ending the session and the signal to clean up the session, which could lead to the execution of arbitrary code as the root user.
US-CERT/NIST reports:
The _zip_name_locate function in zip_name_locate.c in the Zip extension in PHP before 5.3.6 does not properly handle a ZIPARCHIVE::FL_UNCHANGED argument, which might allow context-dependent attackers to cause a denial of service (application crash) via an empty ZIP archive that is processed with a (1) locateName or (2) statName operation.
US-CERT/NIST reports:
exif.c in the Exif extension in PHP before 5.3.6 on 64-bit platforms performs an incorrect cast, which allows remote attackers to cause a denial of service (application crash) via an image with a crafted Image File Directory (IFD) that triggers a buffer over-read.
Adobe Product Security Incident Response Team reports:
A critical vulnerability exists in Adobe Flash Player 10.2.152.33 and earlier versions (Adobe Flash Player 10.2.154.18 and earlier for Chrome users) for Windows, Macintosh, Linux and Solaris operating systems, Adobe Flash Player 10.1.106.16 and earlier versions for Android, and the Authplay.dll component that ships with Adobe Reader and Acrobat X (10.0.1) and earlier 10.x and 9.x versions of Reader and Acrobat for Windows and Macintosh operating systems.
This vulnerability (CVE-2011-0609) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being exploited in the wild in targeted attacks via a Flash (.swf) file embedded in a Microsoft Excel (.xls) file delivered as an email attachment.
The Mozilla Project reports:
MFSA 2011-11 Update to HTTPS certificate blacklist
Wietse Venema has discovered a software flaw that allows an attacker to inject client commands into an SMTP session during the unprotected plaintext SMTP protocol phase, such that the server will execute those commands during the SMTP- over-TLS protocol phase when all communication is supposed to be protected.
Hugo Leisink reports:
A bug has been found in version 7.4 of the Hiawatha webserver, which could lead to a server crash. This is caused by an integer overflow in the routine that reads the HTTP request. A too large value of the Content-Length HTTP header results in an overflow.

US CERT reports:
PivotX contains a vulnerability that allows an attacker to change the password of any account just by guessing the username. Version 2.2.4 has been reported to not be affected. This vulnerability is being exploited in the wild and users should immediately upgrade to 2.2.5 or later. Mitigation steps for users that have been compromised have been posted to the PivotX Support Community.
The Tomcat security team reports:
The HTML Manager interface displayed web applciation provided data, such as display names, without filtering. A malicious web application could trigger script execution by an administartive user when viewing the manager pages.
phpMyAdmin team reports:
It was possible to create a bookmark which would be executed unintentionally by other users.
When the files README, ChangeLog or LICENSE have been removed from their original place (possibly by the distributor), the scripts used to display these files can show their full path, leading to possible further attacks.
Adobe Product Security Incident Response Team reports:
Critical vulnerabilities have been identified in Adobe Flash Player 10.1.102.64 and earlier versions for Windows, Macintosh, Linux, and Solaris. These vulnerabilities could cause the application to crash and could potentially allow an attacker to take control of the affected system.
Secunia reports:
The vulnerability is caused due to an error within the "closedctd()" function in fitz/filt_dctd.c when processing PDF files containing certain malformed JPEG images. This can be exploited to cause a stack corruption by e.g. tricking a user into opening a specially crafted PDF file.
Secunia reports:
Input passed via an email from address is not properly sanitised in the "deliver()" function (lib/mail/network/delivery_methods/sendmail.rb) before being used as a command line argument. This can be exploited to inject arbitrary shell commands.
Plone developer reports:
This is an escalation of privileges attack that can be used by anonymous users to gain access to a Plone site's administration controls, view unpublished content, create new content and modify a site's skin. The sandbox protecting access to the underlying system is still in place, and it does not grant access to other applications running on the same Zope instance.

Opera reports:
Opera 11.01 is a recommended upgrade offering security and stability enhancements.
The following security vulnerabilities have been fixed:
- Removed support for "
javascript:
" URLs in CSS -o-link values, to make it easier for sites to filter untrusted CSS.- Fixed an issue where large form inputs could allow execution of arbitrary code, as reported by Jordi Chancel; see our advisory.
- Fixed an issue which made it possible to carry out clickjacking attacks against internal opera: URLs; see our advisory.
- Fixed issues which allowed web pages to gain limited access to files on the user's computer; see our advisory.
- Fixed an issue where email passwords were not immediately deleted when deleting private data; see our advisory.
Django project reports:
Today the Django team is issuing multiple releases -- Django 1.2.5 and Django 1.1.4 -- to remedy three security issues reported to us. All users of affected versions of Django are urged to upgrade immediately.
Medawiki reports:
An arbitrary script inclusion vulnerability was discovered. The vulnerability only allows execution of files with names ending in ".php" which are already present in the local filesystem. Only servers running Microsoft Windows and possibly Novell Netware are affected. Despite these mitigating factors, all users are advised to upgrade, since there is a risk of complete server compromise. MediaWiki 1.8.0 and later is affected.
Security researcher mghack discovered a CSS injection vulnerability. For Internet Explorer and similar browsers, this is equivalent to an XSS vulnerability, that is to say, it allows the compromise of wiki user accounts. For other browsers, it allows private data such as IP addresses and browsing patterns to be sent to a malicious external web server. It affects all versions of MediaWiki. All users are advised to upgrade.
Vendor reports:
SQL injection vulnerability in the do_trackbacks function in wp-includes/comment.php in WordPress before 3.0.2 allows remote authenticated users to execute arbitrary SQL commands via the Send Trackbacks field.
VLC team reports:
When parsing an invalid MKV (Matroska or WebM) file, input validation are insufficient.
MaraDNS developer Sam Trenholme reports:
... a mistake in allocating an array of integers, allocating it in bytes instead of sizeof(int) units. This resulted in a buffer being too small, allowing it to be overwritten. The impact of this programming error is that MaraDNS can be crashed by sending MaraDNS a single "packet of death". Since the data placed in the overwritten array cannot be remotely controlled (it is a list of increasing integers), there is no way to increase privileges exploiting this bug.
ISC reports:
When the DHCPv6 server code processes a message for an address that was previously declined and internally tagged as abandoned it can trigger an assert failure resulting in the server crashing. This could be used to crash DHCPv6 servers remotely. This issue only affects DHCPv6 servers. DHCPv4 servers are unaffected.
A Bugzilla Security Advisory reports:
This advisory covers three security issues that have recently been fixed in the Bugzilla code:
- A weakness in Bugzilla could allow a user to gain unauthorized access to another Bugzilla account.
- A weakness in the Perl CGI.pm module allows injecting HTTP headers and content to users via several pages in Bugzilla.
- If you put a harmful "javascript:" or "data:" URL into Bugzilla's "URL" field, then there are multiple situations in which Bugzilla will unintentionally make that link clickable.
- Various pages lack protection against cross-site request forgeries.
All affected installations are encouraged to upgrade as soon as possible.
Dokuwiki reports:
This security update fixes problems in the XMLRPC interface where ACLs where not checked correctly sometimes, making it possible to access and write information that should not have been accessible/writable. This only affects users who have enabled the XMLRPC interface (default is off) and have enabled XMLRPC access for users who can't access/write all content anyway (default is nobody, see http://www.dokuwiki.org/config:xmlrpcuser for details).
This update also includes a fix for a problem in the general ACL checking function that could be exploited to gain access to restricted pages and media files in rare conditions (when you had rights for an id you could get the same rights on ids where one character has been replaced by a ".").
The Asterisk Development Team reports:
The releases of Asterisk 1.4.38.1, 1.4.39.1, 1.6.1.21, 1.6.2.15.1, 1.6.2.16.2, 1.8.1.2, and 1.8.2.1 resolve an issue when forming an outgoing SIP request while in pedantic mode, which can cause a stack buffer to be made to overflow if supplied with carefully crafted caller ID information. The issue and resolution are described in the AST-2011-001 security advisory.
Colin Percival reports:
In versions 1.0.22 through 1.0.27 of Tarsnap, the CTR nonce value is not incremented after each chunk is encrypted. (The CTR counter is correctly incremented after each 16 bytes of data was processed, but this counter is reset to zero for each new chunk.)
Note that since the Tarsnap client-server protocol is encrypted, being able to intercept Tarsnap client-server traffic does not provide an attacker with access to the data.
The MoinMoin developers reports:

The Tor Project reports:
A remote heap overflow vulnerability that can allow remote code execution. Other fixes address a variety of assert and crash bugs, most of which we think are hard to exploit remotely. All Tor users should upgrade.
Todd Miller reports:
Beginning with sudo version 1.7.0 it has been possible to grant permission to run a command using a specified group via sudo's -g option (run as group), if allowed by the sudoers file. A flaw exists in sudo's password checking logic that allows a user to run a command with only the group changed without being prompted for a password.
Entry for CVE-2010-4539 says:
The walk function in repos.c in the mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion before 1.6.15, allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that trigger the walking of SVNParentPath collections.
Entry for CVE-2010-4644 says:
Multiple memory leaks in rev_hunt.c in Apache Subversion before 1.6.15 allow remote authenticated users to cause a denial of service (memory consumption and daemon crash) via the -g option to the blame command.
PHP developers reports:
Security Enhancements and Fixes in PHP 5.3.5:
- Fixed bug #53632 (PHP hangs on numeric value 2.2250738585072011e-308). (CVE-2010-4645)
Security Enhancements and Fixes in PHP 5.2.17:
- Fixed bug #53632 (PHP hangs on numeric value 2.2250738585072011e-308). (CVE-2010-4645)
David Woodhouse reports:
Secondly a privilege escalation where the trusted 'exim' user is able to tell Exim to use arbitrary config files, in which further ${run ...} commands will be invoked as root.
Clickjacking vulnerabilities:
Clickjacking is a type of vulnerability discovered in 2008, which is similar to CSRF. The attack involves displaying the target webpage in a iframe embedded in a malicious website. Using CSS, the submit button of the form on the targeit webpage is made invisible, and then overlaid with some button or link on the malicious website that encourages the user to click on it.
Gustavo Noronha Silva reports:
The patches to fix the following CVEs are included with help from Huzaifa Sidhpurwala from the Red Hat security team.
Django project reports:
Today the Django team is issuing multiple releases -- Django 1.2.4, Django 1.1.3 and Django 1.3 beta 1 -- to remedy two security issues reported to us. All users of affected versions of Django are urged to upgrade immediately.
Information leakage in Django administrative interface
The Django administrative interface, django.contrib.admin supports filtering of displayed lists of objects by fields on the corresponding models, including across database-level relationships. This is implemented by passing lookup arguments in the querystring portion of the URL, and options on the ModelAdmin class allow developers to specify particular fields or relationships which will generate automatic links for filtering.
Denial-of-service attack in password-reset mechanism
Django's bundled authentication framework, django.contrib.auth, offers views which allow users to reset a forgotten password. The reset mechanism involves generating a one-time token composed from the user's ID, the timestamp of the reset request converted to a base36 integer, and a hash derived from the user's current password hash (which will change once the reset is complete, thus invalidating the token).
Drupal security team reports:
The Views module provides a flexible method for Drupal site designers to control how lists and tables of content are presented. Under certain circumstances, Views could display parts of the page path without escaping, resulting in a relected Cross Site Scripting (XSS) vulnerability. An attacker could exploit this to gain full administrative access.
Mitigating factors: This vulnerability only occurs with a specific combination of configuration options for a specific View, but this combination is used in the default Views provided by some additional modules. A malicious user would need to get an authenticated administrative user to visit a specially crafted URL.
Jean-Philippe Lang reports:
This release also fixes 3 security issues reported by joernchen of Phenoelit:
- logged in users may be able to access private data (affected versions: 1.0.x)
- persistent XSS vulnerability in textile formatter (affected versions: all previous releases)
- remote command execution in bazaar repository adapter (affected versions: 0.9.x, 1.0.x)
The Tor Project reports:
Remotely exploitable bug that could be used to crash instances of Tor remotely by overflowing on the heap. Remote-code execution hasn't been confirmed, but can't be ruled out. Everyone should upgrade.
The YUI team reports:
A security-related defect was introduced in the YUI 2 Flash component infrastructure beginning with the YUI 2.4.0 release. This defect allows JavaScript injection exploits to be created against domains that host affected YUI .swf files.
The following DoS conditions in Zip extension were fixed in PHP 5.3.4 and PHP 5.2.15:
Fixed crash in zip extract method (possible CWE-170).
The ZipArchive::getArchiveComment function in PHP 5.2.x through 5.2.14 and 5.3.x through 5.3.3 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted ZIP archive.
The following DoS condition in filter extension was fixed in PHP 5.3.4 and PHP 5.2.15:
Stack consumption vulnerability in the filter_var function in PHP 5.2.x through 5.2.14 and 5.3.x through 5.3.3, when FILTER_VALIDATE_EMAIL mode is used, allows remote attackers to cause a denial of service (memory consumption and application crash) via a long e-mail address string.
The following DoS condition in IMAP extension was fixed in PHP 5.3.4 and PHP 5.2.15:
A remote user can send specially crafted IMAP user name or password data to trigger a double free memory error in 'ext/imap/php_imap.c' and cause the target service to crash.
It may be possible to execute arbitrary code. However, code execution was not confirmed.
Entry for CVE-2010-2094 says:
Multiple format string vulnerabilities in the phar extension in PHP 5.3 before 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the (1) phar_stream_flush, (2) phar_wrapper_unlink, (3) phar_parse_url, or (4) phar_wrapper_open_url functions in ext/phar/stream.c; and the (5) phar_wrapper_open_dir function in ext/phar/dirstream.c, which triggers errors in the php_stream_wrapper_log_error function.
PECL source code for PHAR extension shares the same code, so it is vulnerable too.
PHP-specific version of NULL-byte poisoning was briefly described by ShAnKaR:
Poison NULL byte vulnerability for perl CGI applications was described in [1]. ShAnKaR noted, that same vulnerability also affects different PHP applications.
PHP developers report that branch 5.3 received a fix:
Paths with NULL in them (foo\0bar.txt) are now considered as invalid (CVE-2006-7243).
MITRE reports:
fopen_wrappers.c in PHP 5.3.x through 5.3.3 might allow remote attackers to bypass open_basedir restrictions via vectors related to the length of a filename.
Off-by-one error in the sanity validator for the extract() method allowed attackers to replace the values of $GLOBALS and $this when mode EXTR_OVERWRITE was used.

The MIT Kerberos team reports:
MIT krb5 KDC may issue tickets not requested by a client, based on an attacker-chosen KrbFastArmoredReq.
An authenticated remote attacker that controls a legitimate service principal could obtain a valid service ticket to itself containing valid KDC-generated authorization data for a client whose TGS-REQ it has intercepted. The attacker could then use this ticket for S4U2Proxy to impersonate the targeted client even if the client never authenticated to the subverted service. The vulnerable configuration is believed to be rare.
The MIT Kerberos team reports:
MIT krb5 (releases incorrectly accepts RFC 3961 key-derivation checksums using RC4 keys when verifying AD-SIGNEDPATH and AD-KDC-ISSUED authorization data.
An authenticated remote attacker that controls a legitimate service principal has a 1/256 chance of forging the AD-SIGNEDPATH signature if the TGT key is RC4, allowing it to use self-generated "evidence" tickets for S4U2Proxy, instead of tickets obtained from the user or with S4U2Self. Configurations using RC4 for the TGT key are believed to be rare.
An authenticated remote attacker has a 1/256 chance of forging AD-KDC-ISSUED signatures on authdata elements in tickets having an RC4 service key, resulting in privilege escalation against a service that relies on these signatures. There are no known uses of the KDC-ISSUED authdata container at this time.
The MIT Kerberos team reports:
MIT krb5 incorrectly accepts an unkeyed checksum for PAC signatures.
An authenticated remote attacker can forge PACs if using a KDC that does not filter client-provided PAC data. This can result in privilege escalation against a service that relies on PAC contents to make authorization decisions.
The MIT Kerberos team reports:
MIT krb incorrectly accepts an unkeyed checksum with DES session keys for version 2 (RFC 4121) of the GSS-API krb5 mechanism.
An unauthenticated remote attacker can forge GSS tokens that are intended to be integrity-protected but unencrypted, if the targeted pre-existing application session uses a DES session key.
MIT krb5 KDC incorrectly accepts RFC 3961 key-derivation checksums using RC4 keys when verifying the req-checksum in a KrbFastArmoredReq.
An unauthenticated remote attacker has a 1/256 chance of swapping a client-issued KrbFastReq into a different KDC-REQ, if the armor key is RC4. The consequences are believed to be minor.
The MIT Kerberos team reports:
MIT krb5 clients incorrectly accept an unkeyed checksums in the SAM-2 preauthentication challenge.
An unauthenticated remote attacker could alter a SAM-2 challenge, affecting the prompt text seen by the user or the kind of response sent to the KDC. Under some circumstances, this can negate the incremental security benefit of using a single-use authentication mechanism token.
MIT krb5 incorrectly accepts RFC 3961 key-derivation checksums using RC4 keys when verifying KRB-SAFE messages.
An unauthenticated remote attacker has a 1/256 chance of forging KRB-SAFE messages in an application protocol if the targeted pre-existing session uses an RC4 session key. Few application protocols use KRB-SAFE messages.
The ProFTPD Project team reports:
The security issue is caused due to the distribution of compromised ProFTPD 1.3.3c source code packages via the project's main FTP server and all of the mirror servers, which contain a backdoor allowing remote root access.
phpMyAdmin team reports:
It was possible to conduct a XSS attack using spoofed request on the db search script.
ISC reports:
If the server receives a DHCPv6 packet containing one or more Relay-Forward messages, and none of them supply an address in the Relay-Forward link-address field, then the server will crash. This can be used as a single packet crash attack vector.
The OpenTTD Team reports:
When a client disconnects, without sending the "quit" or "client error" message, the server has a chance of reading and writing a just freed piece of memory. The writing can only happen while the server is sending the map. Depending on what happens directly after freeing the memory there is a chance of segmentation fault, and thus a denial of service.
The Horde team reports:
The major changes compared to Horde version 3.3.10 are:
* Fixed XSS vulnerability when viewing details of a vCard.
Tippingpoint reports:
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of ProFTPD. Authentication is not required to exploit this vulnerability.
The flaw exists within the proftpd server component which listens by default on TCP port 21. When reading user input if a TELNET_IAC escape sequence is encountered the process miscalculates a buffer length counter value allowing a user controlled copy of data to a stack buffer. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the proftpd process.
OpenSSL Team reports:
Rob Hulswit has found a flaw in the OpenSSL TLS server extension code parsing which on affected servers can be exploited in a buffer overrun attack.
Any OpenSSL based TLS server is vulnerable if it is multi-threaded and uses OpenSSL's internal caching mechanism. Servers that are multi-process and/or disable internal session caching are NOT affected.
In particular the Apache HTTP server (which never uses OpenSSL internal caching) and Stunnel (which includes its own workaround) are NOT affected.
Adobe Product Security Incident Response Team reports:
Critical vulnerabilities have been identified in Adobe Flash Player 10.1.85.3 and earlier versions for Windows, Macintosh, Linux, and Solaris, and Adobe Flash Player 10.1.95.1 for Android. These vulnerabilities, including CVE-2010-3654 referenced in Security Advisory APSA10-05, could cause the application to crash and could potentially allow an attacker to take control of the affected system.
Secunia reports:
A vulnerability has been discovered in Wireshark, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an infinite recursion error in the "dissect_unknown_ber()" function in epan/dissectors/packet-ber.c and can be exploited to cause a stack overflow e.g. via a specially crafted SNMP packet.
The vulnerability is confirmed in version 1.4.0 and reported in version 1.2.11 and prior and version 1.4.0 and prior.
Secunia reports:
Two vulnerabilities have been reported in Mailman, which can be exploited by malicious users to conduct script insertion attacks.
Certain input passed via the list descriptions is not properly sanitised before being displayed to the user. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
Successful exploitation requires "list owner" permissions.
OTRS Security Advisory reports:
- Multiple Cross Site Scripting issues: Missing HTML quoting allows authenticated agents or customers to inject HTML tags. This vulnerability allows an attacker to inject script code into the OTRS web-interface which will be loaded and executed in the browsers of system users.
- Possible Denial of Service Attack: Perl's regular expressions consume 100% CPU time on the server if an agent or customer views an affected article. To exploit this vulnerability the malicious user needs to send extremely large HTML emails to your system address.
AgentTicketZoom is vulnerable to XSS attacks from HTML e-mails:
Whenever a customer sends an HTML e-mail and RichText is enabled in OTRS, javascript contained in the email can do everything in the OTRS agent interface that the agent himself could do.
Most relevant is that this type of exploit can be used in such a way that the agent won't even detect he is being exploited.
The Mozilla Project reports:
MFSA 2010-73 Heap buffer overflow mixing document.write and DOM insertion
The Opera Desktop Team reports:
- Fixed an issue that allowed cross-domain checks to be bypassed, allowing limited data theft using CSS, as reported by Isaac Dawson.
- Fixed an issue where manipulating the window could be used to spoof the page address.
- Fixed an issue with reloads and redirects that could allow spoofing and cross-site scripting.
- Fixed an issue that allowed private video streams to be intercepted, as reported by Nirankush Panchbhai of Microsoft Vulnerability Research.
- Fixed an issue that caused JavaScript to run in the wrong security context after manual interaction.
Secunia reports:
A vulnerability has been reported in bzip2, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.
The vulnerability is caused due to an integer overflow in the "BZ2_decompress()" function in decompress.c and can be exploited to cause a crash or potentially execute arbitrary code.
When decompressing data, the run-length encoded values are not adequately sanity-checked, allowing for an integer overflow.
The read-only flag is not correctly copied when a mbuf buffer reference is duplicated. When the sendfile(2) system call is used to transmit data over the loopback interface, this can result in the backing pages for the transmitted file being modified, causing data corruption.
The NFS client subsystem fails to correctly validate the length of a parameter provided by the user when a filesystem is mounted.
A programming error in the OPIE library could allow an off-by-one buffer overflow to write a single zero byte beyond the end of an on-stack buffer.
The jail(8) utility does not change the current working directory while imprisoning. The current working directory can be accessed by its descendants.
When replaying setattr transaction, the replay code would set the attributes with certain insecure defaults, when the logged transaction did not touch these attributes.
If ntpd receives a mode 7 (MODE_PRIVATE) request or error response from a source address not listed in either a 'restrict ... noquery' or a 'restrict ... ignore' section it will log the even and send a mode 7 error response.
If a client requests DNSSEC records with the Checking Disabled (CD) flag set, BIND may cache the unvalidated responses. These responses may later be returned to another client that has not set the CD flag.
When downloading updates to FreeBSD via 'freebsd-update fetch' or 'freebsd-update upgrade', the freebsd-update(8) utility copies currently installed files into its working directory (/var/db/freebsd-update by default) both for the purpose of merging changes to configuration files and in order to be able to roll back installed updates.
The default working directory used by freebsd-update(8) is normally created during the installation of FreeBSD with permissions which allow all local users to see its contents, and freebsd-update(8) does not take any steps to restrict access to files stored in said directory.
When running setuid programs rtld will normally remove potentially dangerous environment variables. Due to recent changes in FreeBSD environment variable handling code, a corrupt environment may result in attempts to unset environment variables failing.
The SSL version 3 and TLS protocols support session renegotiation without cryptographically tying the new session parameters to the old parameters.
The monotone developers report:
Running "mtn ''" or "mtn ls ''" doesn't cause an internal error anymore. In monotone 0.48 and earlier this behavior could be used to crash a server remotely (but only if it was configured to allow execution of remote commands).

Gustavo Noronha Silva reports:
The patches to fix the following CVEs are included with help from Vincent Danen and other members of the Red Hat security team:
Secunia reports:
Multiple vulnerabilities have been reported in APR-util, which can be exploited by malicious people to cause a DoS (Denial of Service).
Two XML parsing vulnerabilities exist in the bundled version of expat.
An error within the "apr_brigade_split_line()" function in buckets/apr_brigade.c can be exploited to cause high memory consumption.
The phpMyFAQ project reports:
The phpMyFAQ Team has learned of a security issue that has been discovered in phpMyFAQ 2.6.x: phpMyFAQ doesn't sanitize some variables in different pages correctly. With a properly crafted URL it is e.g. possible to inject JavaScript code into the output of a page, which could result in the leakage of domain cookies (f.e. session identifiers)..
The Horde team reports:
The major changes compared to Gollem version H3 (1.1.1) are:
* Fixed an XSS vulnerability in the file viewer.
The Horde team reports:
Thanks to Naumann IT Security Consulting for reporting the XSS vulnerability.
The major changes compared to IMP version H3 (4.3.7) are:
* Fixed an XSS vulnerability in the Fetchmail configuration.
The Horde team reports:
Thanks to Naumann IT Security Consulting for reporting the XSS vulnerability.
Thanks to Secunia for releasing an advisory for the new CSRF protection in the preference interface
The major changes compared to Horde version 3.3.8 are:
* Fixed XSS vulnerability in util/icon_browser.php.
* Protected preference forms against CSRF attacks.
The OpenX project reported:
It has been brought to our attention that there is a vulnerability in the 2.8 downloadable version of OpenX that can result in a server running the downloaded version of OpenX being compromised.
This vulnerability exists in the file upload functionality and allows attackers to upload and execute PHP code of their choice.
Squid security advisory 2010:3 reports:
Due to an internal error in string handling Squid is vulnerable to a denial of service attack when processing specially crafted requests.
This problem allows any trusted client to perform a denial of service attack on the Squid service.
Adobe Product Security Incident Response Team reports:
A critical vulnerability exists in Adobe Flash Player 10.1.82.76 and earlier versions for Windows, Macintosh, Linux, Solaris, and Adobe Flash Player 10.1.92.10 for Android. This vulnerability also affects Adobe Reader 9.3.4 and earlier versions for Windows, Macintosh and UNIX, and Adobe Acrobat 9.3.4 and earlier versions for Windows and Macintosh. This vulnerability (CVE-2010-2884) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being actively exploited in the wild against Adobe Flash Player on Windows. Adobe is not aware of any attacks exploiting this vulnerability against Adobe Reader or Acrobat to date.
Django project reports:
The provided template tag for inserting the CSRF token into forms -- {% csrf_token %} -- explicitly trusts the cookie value, and displays it as-is. Thus, an attacker who is able to tamper with the value of the CSRF cookie can cause arbitrary content to be inserted, unescaped, into the outgoing HTML of the form, enabling cross-site scripting (XSS) attacks.
Gustavo Noronha Silva reports:
With help from Vincent Danen and other members of the Red Hat security team, the following CVE's where fixed.
Description for CVE-2008-3432 says:
Heap-based buffer overflow in the mch_expand_wildcards function in os_unix.c in Vim 6.2 and 6.3 allows user-assisted attackers to execute arbitrary code via shell metacharacters in filenames, as demonstrated by the netrw.v3 test case.

Todd Miller reports:
Beginning with sudo version 1.7.0 it has been possible to grant permission to run a command using a specified group via sudo -g option (run as group). A flaw exists in the logic that matches Runas groups in the sudoers file when the -u option is also specified (run as user). This flaw results in a positive match for the user specified via -u so long as the group specified via -g is allowed by the sudoers file.
Exploitation of the flaw requires that Sudo be configured with sudoers entries that contain a Runas group. Entries that do not contain a Runas group, or only contain a Runas user are not affected.
The get1 command, as used by lftpget, in LFTP before 4.0.6 does not properly validate a server-provided filename before determining the destination filename of a download, which allows remote servers to create or overwrite arbitrary files via a Content-Disposition header that suggests a crafted filename, and possibly execute arbitrary code as a consequence of writing to a dotfile in a home directory.
GNU Wget version 1.12 and earlier uses a server-provided filename instead of the original URL to determine the destination filename of a download, which allows remote servers to create or overwrite arbitrary files via a 3xx redirect to a URL with a .wgetrc filename followed by a 3xx redirect to a URL with a crafted filename, and possibly execute arbitrary code as a consequence of writing to a dotfile in a home directory.
lwp-download in libwww-perl before 5.835 does not reject downloads to filenames that begin with a `.' (dot) character, which allows remote servers to create or overwrite files via a 3xx redirect to a URL with a crafted filename or a Content-Disposition header that suggests a crafted filename, and possibly execute arbitrary code as a consequence of writing to a dotfile in a home directory.
The Red Hat security team reported two vulnerabilities:
A stack buffer overflow flaw was found in the way Quagga's bgpd daemon processed Route-Refresh messages. A configured Border Gateway Protocol (BGP) peer could send a Route-Refresh message with specially-crafted Outbound Route Filtering (ORF) record, which would cause the master BGP daemon (bgpd) to crash or, possibly, execute arbitrary code with the privileges of the user running bgpd.
A NULL pointer dereference flaw was found in the way Quagga's bgpd daemon parsed paths of autonomous systems (AS). A configured BGP peer could send a BGP update AS path request with unknown AS type, which could lead to denial of service (bgpd daemon crash).
A Bugzilla Security Advisory reports:
- Remote Information Disclosure: An unprivileged user is normally not allowed to view other users' group membership. But boolean charts let the user use group-based pronouns, indirectly disclosing group membership. This security fix restricts the use of pronouns to groups the user belongs to.
- Notification Bypass: Normally, when a user is impersonated, he receives an email informing him that he is being impersonated, containing the identity of the impersonator. However, it was possible to impersonate a user without this notification being sent.
- Remote Information Disclosure: An error message thrown by the "Reports" and "Duplicates" page confirmed the non-existence of products, thus allowing users to guess confidential product names. (Note that the "Duplicates" page was not vulnerable in Bugzilla 3.6rc1 and above though.)
- Denial of Service: If a comment contained the phrases "bug X" or "attachment X", where X was an integer larger than the maximum 32-bit signed integer size, PostgreSQL would throw an error, and any page containing that comment would not be viewable. On most Bugzillas, any user can enter a comment on any bug, so any user could have used this to deny access to one or all bugs. Bugzillas running on databases other than PostgreSQL are not affected.
The OpenTTD Team reports:
When multiple commands are queued (at the server) for execution in the next game tick and an client joins the server can get into an infinite loop. With the default settings triggering this bug is difficult (if not impossible), however the larger value of the "frame_freq" setting is easier it is to trigger the bug.
The affected corkscrew versions use sscanf calls without proper bounds checking. In the authentication file parsing routine this can cause an exploitable buffer overflow condition. A similar but issue exists in the server response code but appears to be non-exploitable.
phpMyAdmin Team reports:
It was possible to conduct a XSS attack using crafted URLs org POST parameters on several pages.
SLiM assigns logged on users a PATH in which the current working directory ("./") is included. This PATH can allow unintentional code execution through planted binaries and has therefore been fixed SLiM version 1.3.2.
The official ruby site reports:
WEBrick have had a cross-site scripting vulnerability that allows an attacker to inject arbitrary script or HTML via a crafted URI. This does not affect user agents that strictly implement HTTP/1.1, however, some user agents do not.
Isolate currently suffers from some bad security bugs! These are local root privilege escalation bugs. Thanks to the helpful person who reported them (email Chris if you want credit!). We're working to fix them ASAP, but until then, isolate is unsafe and you should uninstall it. Sorry!
VideoLAN project reports:
VLC fails to perform sufficient input validation when trying to extract some meta-informations about input media through ID3v2 tags. In the failure case, VLC attempt dereference an invalid memory address, and a crash will ensure.
Adobe Product Security Incident Response Team reports:
Critical vulnerabilities have been identified in Adobe Flash Player version 10.1.53.64 and earlier. These vulnerabilities could cause the application to crash and could potentially allow an attacker to take control of the affected system.
The Opera Destkop Team reports:
- Fixed an issue where heap buffer overflow in HTML5 canvas could be used to execute arbitrary code, as reported by Kuzzcc.
- Fixed an issue where unexpected changes in tab focus could be used to run programs from the Internet, as reported by Jakob Balle and Sven Krewitt of Secunia.
- Fixed an issue where news feed preview could subscribe to feeds without interaction, as reported by Alexios Fakos.

MFSA 2010-48 Dangling pointer crash regression from plugin parameter array fix
Piwik versions 0.6 through 0.6.3 are vulnerable to arbitrary, remote file inclusion using a directory traversal pattern infinite a crafted request for a data renderer.
A vulnerability has been reported in Piwik, which can before exploited by malicious people to disclose potentially sensitive information. Input passed to unspecified parameters when requesting a data renderer is not properly verified before being used to include files. This can be exploited to includes arbitrary files from local resources via directory traversal attacks.
There is a denial of service vulnerability in libmspack. The libmspack code is built into cabextract, so it is also vulnerable.
Secunia reports:
The vulnerability is caused due to an error when copying data from an uncompressed block (block type 0) and can be exploited to trigger an infinite loop by tricking an application using the library into processing specially crafted MS-ZIP archives.
Apache ChangeLog reports:
mod_dav, mod_cache: Fix Handling of requests without a path segment.
Greg Brockman reports:
If an attacker were to create a crafted working copy where the user runs any git command, the attacker could force execution of arbitrary code.
Derek Jones reports:
A fix has been implemented for a security flaw in CodeIgniter 1.7.2. All applications using the File Upload class should install the patch to ensure that their application is not subject to a vulnerability.

Janne Snabb discovered that applications using VTE, such as gnome-terminal, did not correctly filter window and icon title request escape codes. If a user were tricked into viewing specially crafted output in their terminal, a remote attacker could execute arbitrary commands with user privileges.
Gustavo Noronha reports:
Debian's Michael Gilbert has done a great job going through all CVEs released about WebKit, and including patches in the Debian package. 1.2.3 includes all of the commits from trunk to fix those, too.
Eric Davis reports:
This security release addresses some security vulnerabilities found in the advanced subversion integration module (Redmine.pm perl script).
Julius Plenz reports:
I found a bug in the base64_decode function which may cause memory corruption when the function is executed on a malformed base64 encoded string.
If a string starting with an equal-sign is passed to the base64_decode function it triggers a memory corruption that in some cases makes bogofilter crash.
A Bugzilla Security Advisory reports:
- Normally, information about time-tracking (estimated hours, actual hours, hours worked, and deadlines) is restricted to users in the "time-tracking group". However, any user was able, by crafting their own search URL, to search for bugs based using those fields as criteria, thus possibly exposing sensitive time-tracking information by a user seeing that a bug matched their search.
- If $use_suexec was set to "1" in the localconfig file, then the localconfig file's permissions were set as world-readable by checksetup.pl. This allowed any user with local shell access to see the contents of the file, including the database password and the site_wide_secret variable used for CSRF protection.
Two security vulnerabilities have been discovered:
Multiple format string vulnerabilities in the DCC functionality in KVIrc 3.4 and 4.0 have unspecified impact and remote attack vectors.
Directory traversal vulnerability in the DCC functionality in KVIrc 3.4 and 4.0 allows remote attackers to overwrite arbitrary files via unknown vectors.
The PNG project describes the problem in an advisory:
Several versions of libpng through 1.4.2 (and through 1.2.43 in the older series) contain a bug whereby progressive applications such as web browsers (or the rpng2 demo app included in libpng) could receive an extra row of image data beyond the height reported in the header, potentially leading to an out-of-bounds write to memory (depending on how the application is written) and the possibility of execution of an attacker's code with the privileges of the libpng user (including remote compromise in the case of a libpng-based browser visiting a hostile web site).
The Moodle release notes report multiple vulnerabilities which could allow cross site scripting, XSS attacks, unauthorised deletion of attempts in some instances.
Juli Mallett reports:
mdnsd will crash on some systems with a corrupt stack and once that's fixed it will still leak a file descriptor when parsing resolv.conf. The crash is because scanf is used with %10s for a buffer that is only 10 chars long. The buffer size needs increased to 11 chars to hold the trailing NUL. To fix the leak, an fclose needs added.
The Opera Desktop Team reports:
Data URIs are allowed to run scripts that manipulate pages from the site that directly opened them. In some cases, the opening site is not correctly detected. In these cases, Data URIs may erroneously be able to run scripts so that they interact with sites that did not directly cause them to be opened.
Multiple vulnerabilities have been reported to exist in older version of Cacti. The release notes of Cacti 0.8.7f summarizes the problems as follows:
- SQL injection and shell escaping issues

Fixed security vulnerability (heap-related) in PNG decoder. (new bug from 3.1.0)
Tielei Wang:
Multiple integer overflows in inter-color spaces conversion tools in libtiff 3.8 through 3.8.2, 3.9, and 4.0 allow context-dependent attackers to execute arbitrary code via a TIFF image with large (1) width and (2) height values, which triggers a heap-based buffer overflow in the (a) cvt_whole_image function in tiff2rgba and (b) tiffcvt function in rgb2ycbcr.
Adobe Product Security Incident Response Team reports:
Critical vulnerabilities have been identified in Adobe Flash Player version 10.0.45.2 and earlier. These vulnerabilities could cause the application to crash and could potentially allow an attacker to take control of the affected system.
Kevin Finisterre reports:
Multiple integer overflows in the handling of TIFF files may result in a heap buffer overflow. Opening a maliciously crafted TIFF file may lead to an unexpected application termination or arbitrary code execution. The issues are addressed through improved bounds checking. Credit to Kevin Finisterre of digitalmunition.com for reporting these issues.
Todd Miller reports:
Most versions of the C library function getenv() return the first instance of an environment variable to the caller. However, some programs, notably the GNU Bourne Again SHell (bash), do their own environment parsing and may choose the last instance of a variable rather than the first one.
An attacker may manipulate the environment of the process that executes Sudo such that a second PATH variable is present. When Sudo runs a bash script, it is this second PATH variable that is used by bash, regardless of whether or not Sudo has overwritten the first instance of PATH. This may allow an attacker to subvert the program being run under Sudo and execute commands he/she would not otherwise be allowed to run.
Ziproxy 3.0.1 release fixes a security vulnerability related to atypical huge picture files (>4GB of size once expanded).
Two security vulnerabilities were discovered:
Noncompliant CSS parsing behaviour in Internet Explorer allows attackers to construct CSS strings which are treated as safe by previous versions of MediaWiki, but are decoded to unsafe strings by Internet Explorer.
A CSRF vulnerability was discovered in our login interface. Although regular logins are protected as of 1.15.3, it was discovered that the account creation and password reset reset features were not protected from CSRF. This could lead to unauthorised access to private wikis.
The Redmine release announcement reports that several cross side scripting vulnerabilities and a potential data disclosure vulnerability have been fixed in the latest release.
A vulnerability found in the DOCSIS dissector can cause Wireshark to crash when a malformed packet trace file is opened. This means that an attacker will have to trick a victim into opening such a trace file before being able to crash the application
The Piwik security advisory reports:
A non-persistent, cross-site scripting vulnerability (XSS) was found in Piwik's Login form that reflected the form_url parameter without being properly escaped or filtered.
The spamassassin milter plugin contains a vulnerability that can allow remote attackers to execute commands on affected systems.
The vulnerability can be exploited trough a special-crafted email header when the plugin was started with the '-x' (expand) flag.
A MediaWiki security announcement reports:
MediaWiki was found to be vulnerable to login CSRF. An attacker who controls a user account on the target wiki can force the victim to log in as the attacker, via a script on an external website.
If the wiki is configured to allow user scripts, say with "$wgAllowUserJs = true" in LocalSettings.php, then the attacker can proceed to mount a phishing-style attack against the victim to obtain their password.
Dan Rosenberg reports:
There are several cross-site scripting vulnerabilities in LXR. These vulnerabilities could allow an attacker to execute scripts in a user's browser, steal cookies associated with vulnerable domains, redirect the user to malicious websites, etc.
VideoLAN project reports:
VLC media player suffers from various vulnerabilities when attempting to parse malformatted or overly long byte streams.
Joomla! reported the following vulnerabilities:
If a user entered a URL with a negative query limit or offset, a PHP notice would display revealing information about the system..
The migration script in the Joomla! installer does not check the file type being uploaded. If the installation application is present, an attacker could use it to upload malicious files to a server.
Session id doesn't get modified when user logs in. A remote site may be able to forward a visitor to the Joomla! site and set a specific cookie. If the user then logs in, the remote site can use that cookie to authenticate as that user.
When a user requests a password reset, the reset tokens were stored in plain text in the database. While this is not a vulnerability in itself, it allows user accounts to be compromised if there is an extension on the site with an SQL injection vulnerability.
Bonsai information security reports:
A Vulnerability has been discovered in Cacti, which can be exploited by any user to conduct SQL Injection attacks. Input passed via the "export_item_id" parameter to "templates_export.php" script is not properly sanitized before being used in a SQL query.
The same source also reported a command execution vulnerability. This second issue can be exploited by Cacti users who have the rights to modify device or graph configurations.
The Moodle release notes report multiple vulnerabilities which could allow remote attackers to perform, amongst others, cross site scripting, user enumeration and SQL injection attacks.
The Apache software foundation reports:
The "WWW-Authenticate" header for BASIC and DIGEST authentication includes a realm name. If a <realm-name> element is specified for the application in web.xml it will be used. However, a <realm-name> is not specified then Tomcat will generate one.
In some circumstances this can expose the local hostname or IP address of the machine running Tomcat.
The MIT Kerberos team reports:
An authenticated remote attacker can crash the KDC by inducing the KDC to perform a double free. Under some circumstances on some platforms, this could also allow malicious code execution.
Secunia Research reported two vulnerabilities in e107:
The first problem affects installations that have the Content Manager plugin enabled. This plugin does not sanitize the "content_heading" parameter correctly and is therefore vulnerable to a cross site scripting attack.
The second vulnerability is related to the avatar upload functionality. Images containing PHP code can be uploaded and executed.
Fetchmail developer Matthias Andree reported a vulnerability that allows remote attackers to crash the application when it is runs in verbose mode.
Fetchmail before release 6.3.17 did not properly sanitize external input (mail headers and UID). When a multi-character locale (such as UTF-8) was in use, this could cause memory exhaustion and thus a denial of service.
Three denial of service vulnerabilities where found in pidgin and allow remote attackers to crash the application. The developers summarized these problems as follows:
Pidgin can become unresponsive when displaying large numbers of smileys
Certain nicknames in group chat rooms can trigger a crash in Finch
Failure to validate all fields of an incoming message can trigger a crash
A vulnerability in libpng can result in denial of service conditions when a remote attacker tricks a victim to open a specially-crafted PNG file.
The PNG project describes the problem in an advisory:
Because of the efficient compression method used in Portable Network Graphics (PNG) files, a small PNG file can expand tremendously, acting as a "decompression bomb".
Malformed PNG chunks can consume a large amount of CPU and wall-clock time and large amounts of memory, up to all memory available on a system
The cURL project reports in a security advisory:
Using the affected libcurl version to download compressed content over HTTP, an application can ask libcurl to automatically uncompress data. When doing so, libcurl can wrongly send data up to 64K in size to the callback which thus is much larger than the documented maximum size.
An application that blindly trusts libcurl's max limit for a fixed buffer size or similar is then a possible target for a buffer overflow vulnerability.
The Red Hat security response team reports:
A remotely exploitable DoS from XMPP client to ejabberd server via too many "client2server" messages (causing the message queue on the server to get overloaded, leading to server crash) has been found.
Two vulnerabilities have found in irssi. The first issue could allow man-in-the-middle attacks due to a missing comparison of SSL server hostnames and the certificate domain names (e.g. CN).
A second vulnerability, related to the nick matching code, could be triggered by remote attackers in order to crash an irssi client when leaving a channel.
An authenticated remote attacker can causing a denial of service by using a newer version of the kadmin protocol than the server supports.
The MIT Kerberos team also reports the cause:
The Kerberos administration daemon (kadmind) can crash due to referencing freed memory.
Two vulnerabilities in krb5 can be used by remote attackers in denial of service attacks. The MIT security advisories report this as follows:
An unauthenticated remote attacker can send an invalid request to a KDC process that will cause it to crash due to an assertion failure, creating a denial of service.
An unauthenticated remote attacker could cause a GSS-API application, including the Kerberos administration daemon (kadmind) to crash.
The Debian security team reports:
It was discovered that mahara, an electronic portfolio, weblog, and resume builder is not properly escaping input when generating a unique username based on a remote user name from a single sign-on application. An attacker can use this to compromise the mahara database via crafted user names.
Todd Miller reports:
Sudo's command matching routine expects actual commands to include one or more slash ('/') characters. The flaw is that sudo's path resolution code did not add a "./" prefix to commands found in the current working directory. This creates an ambiguity between a "sudoedit" command found in the cwd and the "sudoedit" pseudo-command in the sudoers file. As a result, a user may be able to run an arbitrary command named "sudoedit" in the current working directory. For the attack to be successful, the PATH environment variable must include "." and may not include any other directory that contains a "sudoedit" command.
KDE Security Advisory reports:
KDM contains a race condition that allows local attackers to make arbitrary files on the system world-writeable. This can happen while KDM tries to create its control socket during user login. A local attacker with a valid local account can under certain circumstances make use of this vulnerability to execute arbitrary code as root.
The Dojo Toolkit team reports:
Some PHP files did not properly escape input.
Some files could operate like "open redirects". A bad actor could form an URL that looks like it came from a trusted site, but the user would be redirected or load content from the bad actor's site.
A file exposed a more serious cross-site scripting vulnerability with the possibility of executing code on the domain where the file exists.
The Dojo build process defaulted to copying over tests and demos, which are normally not needed and just increased the number of files that could be targets of attacks.
The Zend Framework team reports:
Several files in the bundled Dojo library were identified as having potential exploits, and the Dojo team also advised disabling or removing any PHP scripts in the Dojo library tree when deploying to production.

Egroupware Team report:
Nahuel Grisolia from CYBSEC S.A. Security Systems found two security problems in EGroupware:
Serious remote command execution (allowing to run arbitrary command on the web server by simply issuing a HTTP request!).
A reflected cross-site scripting (XSS).
Both require NO valid EGroupware account and work without being logged in!
Drupal Team reports:
A user-supplied value is directly output during installation allowing a malicious user to craft a URL and perform a cross-site scripting attack. The exploit can only be conducted on sites not yet installed.
The API function drupal_goto() is susceptible to a phishing attack. An attacker could formulate a redirect in a way that gets the Drupal site to send the user to an arbitrarily provided URL. No user submitted data will be sent to that URL.
Locale module and dependent contributed modules do not sanitize the display of language codes, native and English language names properly. While these usually come from a preselected list, arbitrary administrator input is allowed. This vulnerability is mitigated by the fact that the attacker must have a role with the 'administer languages' permission.
Under certain circumstances, a user with an open session that is blocked can maintain his/her session on the Drupal site, despite being blocked.
Todd Miller reports:
When sudo performs its command matching, there is a special case for pseudo-commands in the sudoers file (currently, the only pseudo-command is sudoedit). Unlike a regular command, pseudo-commands do not begin with a slash ('/'). The flaw is that sudo's the matching code would only check against the list of pseudo-commands if the user-specified command also contained no slashes. As a result, if the user ran "sudo ./sudoedit" the normal matching code path was followed, which uses stat(2) to verify that the user-specified command matches the one in sudoers. In this case, it would compare the "./sudoedit" specified by the user with "sudoedit" from the sudoers file, resulting in a positive match.

Lighttpd security advisory reports:
If you send the request data very slow (e.g. sleep 0.01 after each byte), lighttpd will easily use all available memory and die (especially for parallel requests), allowing a DoS within minutes.
Squid security advisory 2010:2 reports:
Due to incorrect processing Squid is vulnerable to a denial of service attack when receiving specially crafted HTCP packets.
This problem allows any machine to perform a denial of service attack on the Squid service when its HTCP port is open.
Adobe Product Security Incident Response Team reports:
A critical vulnerability has been identified in Adobe Flash Player version 10.0.42.34 and earlier. This vulnerability (CVE-2010-0186) could subvert the domain sandbox and make unauthorized cross-domain requests. This update also resolves a potential Denial of Service issue (CVE-2010-0187).
Ray Strode reports:
Under certain circumstances it is possible to circumvent the security of screen locking functionality of gnome-screensaver by changing the systems physical monitor configuration.
gnome-screensaver can lose its keyboard grab when locked, exposing the system to intrusion by adding and removing monitors.
Matthias Andree reports:
In verbose mode, fetchmail prints X.509 certificate subject and issuer information to the user, and counts and allocates a malloc() buffer for that purpose.
If the material to be displayed contains characters with high bit set and the platform treats the "char" type as signed, this can cause a heap buffer overrun because non-printing characters are escaped as \xFF..FFnn, where nn is 80..FF in hex.
Wireshark project reports:
Babi discovered several buffer overflows in the LWRES dissector.
It may be possible to make Wireshark crash remotely or by convincing someone to read a malformed packet trace file.
OTRS Security Advisory reports:
Missing security quoting for SQL statements allows agents and customers to manipulate SQL queries. So it's possible for authenticated users to inject SQL queries via string manipulation of statements.
A malicious user may be able to manipulate SQL queries to read or modify records in the database. This way it could also be possible to get access to more permissions (e. g. administrator permissions).
To use this vulnerability the malicious user needs to have a valid Agent- or Customer-session.
Apache ChangeLog reports:
Integer overflow in the ap_proxy_send_fb function in proxy/proxy_util.c in mod_proxy in the Apache HTTP Server before 1.3.42 on 64-bit platforms allows remote origin servers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a large chunk size that triggers a heap-based buffer overflow.
Squid security advisory 2010:1 reports:
Due to incorrect data validation Squid is vulnerable to a denial of service attack when processing specially crafted DNS packets.
This problem allows any trusted client or external server who can determine the squid receiving port to perform a short-term denial of service attack on the Squid service.
A Bugzilla Security Advisory reports:
When moving a bug from one product to another, an intermediate page is displayed letting you select the groups the bug should be restricted to in the new product. However, a regression in the 3.4.x series made it ignore all groups which are not available in both products. As a workaround, you had to move the bug to the new product first and then restrict it to the desired groups, in two distinct steps, which could make the bug temporarily public.
SecurityFocus reports:
The first affects the /quote HELP module and allows a user to trigger an IRCD crash on some platforms.
The second affects the /links processing module when the flatten_links configuration option is not enabled.
Dokuwiki reports:
The plugin does no checks against cross-site request forgeries (CSRF) which can be exploited to e.g. change the access control rules by tricking a logged in administrator into visiting a malicious web site.
The bug allows listing the names of arbitrary file on the webserver - not their contents. This could leak private information about wiki pages and server structure.
The Zend Framework team reports:
Potential XSS or HTML Injection vector in Zend_Json.
Potential XSS vector in Zend_Service_ReCaptcha_MailHide.

PowerDNS Security Advisory reports:
PowerDNS Recursor up to and including 3.1.7.1 can be brought down and probably exploited.
PowerDNS Recursor up to and including 3.1.7.1 can be spoofed into accepting bogus data
PEAR Security Advisory reports:
Multiple remote arbitrary command injections have been found in the Net_Ping and Net_Traceroute.
When input from forms are used directly, the attacker could pass variables that would allow him to execute remote arbitrary command injections.
Drupal Team reports:
The Contact module does not correctly handle certain user input when displaying category information. Users privileged to create contact categories can insert arbitrary HTML and script code into the contact module administration page. Such a cross-site scripting attack may lead to the malicious user gaining administrative access.
The Menu module does not correctly handle certain user input when displaying the menu administration overview. Users privileged to create new menus can insert arbitrary HTML and script code into the menu module administration page. Such a cross-site scripting attack may lead to the malicious user gaining administrative access.
Denis Barov reports:

secunia reports:
Russ McRee has discovered some vulnerabilities in Pligg, which can be exploited by malicious people to conduct cross-site scripting and request forgery attacks.
Input passed via the "Referer" HTTP header to various scripts (e.g. admin/admin_config.php, admin/admin_modules.php, delete.php, editlink.php, submit.php, submit_groups.php, user_add_remove_links.php, and user_settings.php) is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. create an arbitrary user with administrative privileges if a logged-in administrative user visits a malicious web site.
secunia reports:
Stefan Esser has reported a vulnerability in Piwik, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to the core/Cookie.php script using "unserialize()" with user controlled input. This can be exploited to e.g. execute arbitrary PHP code via the "__wakeup()" or "__destruct()" methods of a serialized object passed via an HTTP cookie.

The Ubuntu security team reports:
It was discovered that libvorbis did not correctly handle certain malformed vorbis files. If a user were tricked into opening a specially crafted vorbis file with an application that uses libvorbis, an attacker could cause a denial of service or possibly execute arbitrary code with the user's privileges.
A Bugzilla Security Advisory reports:
When a bug is in a group, none of its information (other than its status and resolution) should be visible to users outside that group. It was discovered that as of 3.3.2, Bugzilla was showing the alias of the bug (a very short string used as a shortcut for looking up the bug) to users outside of the group, if the protected bug ended up in the "Depends On" or "Blocks" list of any other bug.
The cacti development team reports:
The Cross-Site Scripting patch has been posted.
This patch addresses cross-site scripting issues reported by Moritz Naumann.
secunia reports:
The security issue is caused due to the wp_check_filetype() function in /wp-includes/functions.php improperly validating uploaded files. This can be exploited to execute arbitrary PHP code by uploading a malicious PHP script with multiple extensions.
Successful exploitation of this vulnerability requires that Apache is not configured to handle the mime-type for media files with an e.g. "gif", "jpg", "png", "tif", "wmv" extension.
Input passed via certain parameters to press-this.php is not properly sanitised before being displayed to the user. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
CVE reports:
The decode_entities function in util.c in HTML-Parser before 3.63 allows context-dependent attackers to cause a denial of service (infinite loop) via an incomplete SGML numeric character reference, which triggers generation of an invalid UTF-8 character.
CVE reports:
The _gdGetColors function in gd_gd.c in PHP 5.2.11 and 5.3.0, and the GD Graphics Library 2.x, does not properly verify a certain colorsTotal structure member, which might allow remote attackers to conduct buffer overflow or buffer over-read attacks via a crafted GD file, a different vulnerability than CVE-2009-3293.
TYPO3 develop team reports:
Affected versions: TYPO3 versions 4.0.13 and below, 4.1.12 and below, 4.2.9 and below, 4.3.0beta1 and below.

VideoLAN reports:
When parsing a MP4, ASF or AVI file with an overly deep box structure, a stack overflow might occur. It would overwrite the return address and thus redirect the execution flow.
If successful, a malicious third party could trigger execution of arbitrary code within the context of the VLC media player.
oCERT reports:
Ark input sanitization errors: The KDE archiving tool, Ark, performs insufficient validation which leads to specially crafted archive files, using unknown MIME types, to be rendered using a KHTML instance, this can trigger uncontrolled XMLHTTPRequests to remote sites.
IO Slaves input sanitization errors: KDE protocol handlers perform insufficient input validation, an attacker can craft malicious URI that would trigger JavaScript execution. Additionally the 'help://' protocol handler suffer from directory traversal. It should be noted that the scope of this issue is limited as the malicious URIs cannot be embedded in Internet hosted content.
KMail input sanitization errors: The KDE mail client, KMail, performs insufficient validation which leads to specially crafted email attachments, using unknown MIME types, to be rendered using a KHTML instance, this can trigger uncontrolled XMLHTTPRequests to remote sites.
The exploitation of these vulnerabilities is unlikely according to Portcullis and KDE but the execution of active content is nonetheless unexpected and might pose a threat.
Opera Team Reports:
- Fixed an issue where certain domain names could allow execution of arbitrary code, as reported by Chris Weber of Casaba Security
- Fixed an issue where scripts can run on the feed subscription page, as reported by Inferno
Securityfocus reports:
cTorrent and dTorrent are prone to a remote buffer-overflow vulnerability because the software fails to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.
Successful exploits allow remote attackers to execute arbitrary machine code in the context of a vulnerable application. Failed exploit attempts will likely result in denial-of-service conditions.

Attackers may leverage this issue to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions.
SquidGuard website reports:
Patch 20091015 fixes one buffer overflow problem in sgLog.c when overlong URLs are requested. SquidGuard will then go into emergency mode were no blocking occurs. This is not required in this situation.
Patch 20091019 fixes two bypass problems with URLs which length is close to the limit defined by MAX_BUF (default: 4096) in squidGuard and MAX_URL (default: 4096 in squid 2.x and 8192 in squid 3.x) in squid. For this kind of URLs the proxy request exceeds MAX_BUF causing squidGuard to complain about not being able to parse the squid request. Increasing the buffer limit to be higher than the one defined in MAX_URL solves the issue.

mybb team reports:
Input passed via avatar extensions is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by uploading specially named avatars.
The script allows to sign up with usernames containing zero width space characters, which can be exploited to e.g. conduct spoofing attacks.
Drupal Team reports:
The core OpenID module does not correctly implement Form API for the form that allows one to link user accounts with OpenID identifiers. A malicious user is therefore able to use cross site request forgeries to add attacker controlled OpenID identities to existing accounts. These OpenID identities can then be used to gain access to the affected accounts.
The OpenID module is not a compliant implementation of the OpenID Authentication 2.0 specification. An implementation error allows a user to access the account of another user when they share the same OpenID 2.0 provider.
File uploads with certain extensions are not correctly processed by the File API. This may lead to the creation of files that are executable by Apache. The .htaccess that is saved into the files directory by Drupal should normally prevent execution. The files are only executable when the server is configured to ignore the directives in the .htaccess file.
Drupal doesn't regenerate the session ID when an anonymous user follows the one time login link used to confirm email addresses and reset forgotten passwords. This enables a malicious user to fix and reuse the session id of a victim under certain circumstances.
Firewall Builder release notes reports:

SecurityFocus reports:
GnuTLS is prone to multiple remote vulnerabilities:
- A remote code-execution vulnerability.
- A denial-of-service vulnerability.
- A signature-generation vulnerability.
- A signature-verification vulnerability.
An attacker can exploit these issues to potentially execute arbitrary code, trigger denial-of-service conditions, carry out attacks against data signed with weak signatures, and cause clients to accept expired or invalid certificates from servers.
GnuTLS reports:
By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS into 1) not printing the entire CN/SAN field value when printing a certificate and 2) cause incorrect positive matches when matching a hostname against a certificate.
Secunia reports:
A weakness has been reported in memcached, which can be exploited by malicious people to disclose system information.
The weakness is caused due to the application disclosing the content of /proc/self/maps if a stats maps command is received. This can be exploited to disclose e.g. the addresses of allocated memory regions.
WordPress reports:
A specially crafted URL could be requested that would allow an attacker to bypass a security check to verify a user requested a password reset. As a result, the first account without a key in the database (usually the admin account) would have its password reset and a new password would be emailed to the account owner.
Matthias Andree reports:
Moxie Marlinspike demonstrated in July 2009 that some CAs would sign certificates that contain embedded NUL characters in the Common Name or subjectAltName fields of ITU-T X.509 certificates.
Applications that would treat such X.509 strings as NUL-terminated C strings (rather than strings that contain an explicit length field) would only check the part up to and excluding the NUL character, so that certificate names such as www.good.example\0www.bad.example.com would be mistaken as a certificate name for www.good.example. fetchmail also had this design and implementation flaw.
Joomla! Security Center reports:
In com_mailto, it was possible to bypass timeout protection against sending automated emails.
A Subversion Security Advisory reports:
Subversion clients and servers have multiple heap overflow issues in the parsing of binary deltas. This is related to an allocation vulnerability in the APR library used by Subversion.
Clients with commit access to a vulnerable server can cause a remote heap overflow; servers can cause a heap overflow on vulnerable clients that try to do a checkout or update.
This can lead to a DoS (an exploit has been tested) and to arbitrary code execution (no exploit tested, but the possibility is clear).
A Bugzilla Security Advisory reports:
Normally, users are only supposed to see products that they can file bugs against in the "Product" drop-down on the bug-editing page. Instead, users were being shown all products, even those that they normally could not see. Any user who could edit any bug could see all product names.

SILC changelog reports:
An unspecified format string vulnerability exists in silc-client.
The SquirrelMail Web Server has been compromised, and three plugins are affected.
The port of squirrelmail-sasql-plugin is safe (right MD5), and change_pass is not in the FreeBSD ports tree, but multilogin has a wrong MD5.
When named(8) receives a specially crafted dynamic update message an internal assertion check is triggered which causes named(8) to exit.
To trigger the problem, the dynamic update message must contains a record of type "ANY" and at least one resource record set (RRset) for this fully qualified domain name (FQDN) must exist on the server.
An attacker which can send DNS requests to a nameserver can cause it to exit, thus creating a Denial of Service situation.
No generally applicable workaround is available, but some firewalls may be able to prevent nsupdate DNS packets from reaching the nameserver.
NOTE WELL: Merely configuring named(8) to ignore dynamic updates is NOT sufficient to protect it from this vulnerability.
Secunia reports:
A security issue has been reported in Mono, which can be exploited by malicious people to conduct spoofing attacks.
The security issue is caused due to an error when processing certain XML signatures.
Squid security advisory 2009:2 reports:
Due to incorrect buffer limits and related bound checks Squid is vulnerable to a denial of service attack when processing specially crafted requests or responses.
Due to incorrect data validation Squid is vulnerable to a denial of service attack when processing specially crafted responses.
These problems allow any trusted client or external server to perform a denial of service attack on the Squid service.
Squid-2.x releases are not affected.
Mozilla Project reports:
Firefox user zbyte reported a crash that we determined could result in an exploitable memory corruption problem. In certain cases after a return from a native function, such as escape(), the Just-in-Time (JIT) compiler could get into a corrupt state. This could be exploited by an attacker to run arbitrary code such as installing malware.
This vulnerability does not affect earlier versions of Firefox which do not support the JIT feature.
US-CERT reports:
The ISC DHCP dhclient application contains a stack buffer overflow, which may allow a remote, unauthenticated attacker to execute arbitrary code with root privileges.
The Drupal Security Team reports:
Cross-site scripting
The Forum module does not correctly handle certain arguments obtained from the URL. By enticing a suitably privileged user to visit a specially crafted URL, a malicious user is able to insert arbitrary HTML and script code into forum pages. Such a cross-site scripting attack may lead to the malicious user gaining administrative access. Wikipedia has more information about cross-site scripting (XSS).
User signatures have no separate input format, they use the format of the comment with which they are displayed. A user will no longer be able to edit a comment when an administrator changes the comment's input format to a format that is not accessible to the user. However they will still be able to modify their signature, which will then be processed by the new input format.
If the new format is very permissive, via their signature, the user may be able to insert arbitrary HTML and script code into pages or, when the PHP filter is enabled for the new format, execute PHP code. This issue affects Drupal 6.x only.
When an anonymous user fails to login due to mistyping his username or password, and the page he is on contains a sortable table, the (incorrect) username and password are included in links on the table. If the user visits these links the password may then be leaked to external sites via the HTTP referer.
In addition, if the anonymous user is enticed to visit the site via a specially crafted URL while the Drupal page cache is enabled, a malicious user might be able to retrieve the (incorrect) username and password from the page cache.
nfsen reports:
Due to double input checking, a remote command execution security bug exists in all NfSen versions 1.3 and 1.3.1. Users are requested to update to nfsen-1.3.2.

The Drupal Security Team reports:
When outputting user-supplied data Drupal strips potentially dangerous HTML attributes and tags or escapes characters which have a special meaning in HTML. This output filtering secures the site against cross site scripting attacks via user input.
Certain byte sequences that are valid in the UTF-8 specification are potentially dangerous when interpreted as UTF-7. Internet Explorer 6 and 7 may decode these characters as UTF-7 if they appear before the <meta http-equiv="Content-Type" /> tag that specifies the page content as UTF-8, despite the fact that Drupal also sends a real HTTP header specifying the content as UTF-8. This enables attackers to execute cross site scripting attacks with UTF-7. SA-CORE-2009-005 - Drupal core - Cross site scripting contained an incomplete fix for the issue. HTML exports of books are still vulnerable, which means that anyone with edit permissions for pages in outlines is able to insert arbitrary HTML and script code in these exports.
Additionally, the taxonomy module allows users with the 'administer taxonomy' permission to inject arbitrary HTML and script code in the help text of any vocabulary.
US-CERT reports:
The sasl_encode64() function converts a string into base64. The Cyrus SASL library contains buffer overflows that occur because of unsafe use of the sasl_encode64() function.

SecurityFocus reports:
Ghostscript is prone to a remote buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before copying it into a finite-sized buffer.
Exploiting this issue allows remote attackers to overwrite a sensitive memory buffer with arbitrary data, potentially allowing them to execute malicious machine code in the context of the affected application. This vulnerability may facilitate the compromise of affected computers.
oCERT reports:
Pango suffers from a multiplicative integer overflow which may lead to a potentially exploitable, heap overflow depending on the calling conditions.
For example, this vulnerability is remotely reachable in Firefox by creating an overly large document.location value but only results in a process-terminating, allocation error (denial of service).
The affected function is pango_glyph_string_set_size. An overflow check when doubling the size neglects the overflow possible on the subsequent allocation.
Wireshark team reports:
Wireshark 1.0.7 fixes the following vulnerabilities:
- The PROFINET dissector was vulnerable to a format string overflow. (Bug 3382) Versions affected: 0.99.6 to 1.0.6, CVE-2009-1210.
- The Check Point High-Availability Protocol (CPHAP) dissector could crash. (Bug 3269) Versions affected: 0.9.6 to 1.0.6; CVE-2009-1268.
- Wireshark could crash while loading a Tektronix .rf5 file. (Bug 3366) Versions affected: 0.99.6 to 1.0.6, CVE-2009-1269.
Gentoo security team summarizes:
The following issues were reported in CUPS:
- iDefense reported an integer overflow in the _cupsImageReadTIFF() function in the "imagetops" filter, leading to a heap-based buffer overflow (CVE-2009-0163).
- Aaron Siegel of Apple Product Security reported that the CUPS web interface does not verify the content of the "Host" HTTP header properly (CVE-2009-0164).
- Braden Thomas and Drew Yao of Apple Product Security reported that CUPS is vulnerable to CVE-2009-0146, CVE-2009-0147 and CVE-2009-0166, found earlier in xpdf and poppler.
A remote attacker might send or entice a user to send a specially crafted print job to CUPS, possibly resulting in the execution of arbitrary code with the privileges of the configured CUPS user -- by default this is "lp", or a Denial of Service. Furthermore, the web interface could be used to conduct DNS rebinding attacks.
The function ASN1_STRING_print_ex does not properly validate the lengths of BMPString or UniversalString objects before attempting to print them.
An application which attempts to print a BMPString or UniversalString which has an invalid length will crash as a result of OpenSSL accessing invalid memory locations. This could be used by an attacker to crash a remote application.
No workaround is available, but applications which do not use the ASN1_STRING_print_ex function (either directly or indirectly) are not affected.
Debian Security Team reports:
It was discovered that Quagga, an IP routing daemon, could no longer process the Internet routing table due to broken handling of multiple 4-byte AS numbers in an AS path. If such a prefix is received, the BGP daemon crashes with an assert failure leading to a denial of service.
Secunia reports:
A vulnerability has been reported in Openfire which can be exploited by malicious users to bypass certain security restrictions. The vulnerability is caused due to Openfire not properly respecting the no password changes setting which can be exploited to change passwords by sending jabber:iq:auth passwd_change requests to the server.
Drupal Security Team reports:
When outputting user-supplied data Drupal strips potentially dangerous HTML attributes and tags or escapes characters which have a special meaning in HTML. This output filtering secures the site against cross site scripting attacks via user input.
Certain byte sequences that are valid in the UTF-8 specification are potentially dangerous when interpreted as UTF-7. Internet Explorer 6 and 7 may decode these characters as UTF-7 if they appear before the meta http-equiv="Content-Type" tag that specifies the page content as UTF-8, despite the fact that Drupal also sends a real HTTP header specifying the content as UTF-8. This behaviour enables malicious users to insert and execute Javascript in the context of the website if site visitors are allowed to post content.
In addition, Drupal core also has a very limited information disclosure vulnerability under very specific conditions. If a user is tricked into visiting the site via a specially crafted URL and then submits a form (such as the search box) from that page, the information in their form submission may be directed to a third-party site determined by the URL and thus disclosed to the third party. The third party site may then execute a CSRF attack against the submitted form.

A buffer-overflow in Grip occurs when the software processes a response to a CDDB query that has more than 16 matches.
To exploit this issue, an attacker must be able to influence the response to a CDDB query, either by controlling a malicious CDDB server or through some other means. Successful exploits will allow arbitrary code to run.
Some function pointers for netgraph and bluetooth sockets are not properly initialized.
A local user can cause the FreeBSD kernel to execute arbitrary code. This could be used by an attacker directly; or it could be used to gain root privilege or to escape from a jail.
No workaround is available, but systems without local untrusted users are not vulnerable. Furthermore, systems are not vulnerable if they have neither the ng_socket nor ng_bluetooth kernel modules loaded or compiled into the kernel.
Systems with the security.jail.socket_unixiproute_only sysctl set to 1 (the default) are only vulnerable if they have local untrusted users outside of jails.
If the command
# kldstat -v | grep ng_
produces no output, the system is not vulnerable.
The ftpd(8) server splits long commands into several requests. This may result in the server executing a command which is hidden inside another very long command.
This could, with a specifically crafted command, be used in a cross-site request forgery attack.
FreeBSD systems running ftpd(8) server could act as a point of privilege escalation in an attack against users using web browser to access trusted FTP sites.
No workaround is available, but systems not running FTP servers are not vulnerable. Systems not running the FreeBSD ftp(8) server are not affected, but users of other ftp daemons are advised to take care since several other ftp daemons are known to have related bugs.
IPv6 routers may allow "on-link" IPv6 nodes to create and update the router's neighbor cache and forwarding information. A malicious IPv6 node sharing a common router but on a different physical segment from another node may be able to spoof Neighbor Discovery messages, allowing it to update router information for the victim node.
An attacker on a different physical network connected to the same IPv6 router as another node could redirect IPv6 traffic intended for that node. This could lead to denial of service or improper access to private network traffic.
Firewall packet filters can be used to filter incoming Neighbor Solicitation messages but may interfere with normal IPv6 operation if not configured carefully.
Reverse path forwarding checks could be used to make gateways, such as routers or firewalls, drop Neighbor Solicitation messages from nodes with unexpected source addresses on a particular interface.
IPv6 router administrators are encouraged to read RFC 3756 for further discussion of Neighbor Discovery security implications.
When the arc4random(9) random number generator is initialized, there may be inadequate entropy to meet the needs of kernel systems which rely on arc4random(9); and it may take up to 5 minutes before arc4random(9) is reseeded with secure entropy from the Yarrow random number generator.
All security-related kernel subsystems that rely on a quality random number generator are subject to a wide range of possible attacks for the 300 seconds after boot or until 64k of random data is consumed. The list includes:
* GEOM ELI providers with onetime keys. When a provider is configured in a way so that it gets attached at the same time during boot (e.g. it uses the rc subsystem to initialize) it might be possible for an attacker to recover the encrypted data.
* GEOM shsec providers. The GEOM shsec subsytem is used to split a shared secret between two providers so that it can be recovered when both of them are present. This is done by writing the random sequence to one of providers while appending the result of the random sequence on the other host to the original data. If the provider was created within the first 300 seconds after booting, it might be possible for an attacker to extract the original data with access to only one of the two providers between which the secret data is split.
* System processes started early after boot may receive predictable IDs.
* The 802.11 network stack uses arc4random(9) to generate initial vectors (IV) for WEP encryption when operating in client mode and WEP authentication challenges when operating in hostap mode, which may be insecure.
* The IPv4, IPv6 and TCP/UDP protocol implementations rely on a quality random number generator to produce unpredictable IP packet identifiers, initial TCP sequence numbers and outgoing port numbers. During the first 300 seconds after booting, it may be easier for an attacker to execute IP session hijacking, OS fingerprinting, idle scanning, or in some cases DNS cache poisoning and blind TCP data injection attacks.
* The kernel RPC code uses arc4random(9) to retrieve transaction identifiers, which might make RPC clients vulnerable to hijacking attacks.
No workaround is available for affected systems.
SecurityFocus reports:
The xterm program is prone to a remote command-execution vulnerability because it fails to sufficiently validate user input.
Successfully exploiting this issue would allow an attacker to execute arbitrary commands on an affected computer in the context of the affected application.
According to CVE-2008-5498 entry:
Array index error in the "imageRotate" function in PHP 5.2.8 and earlier allows context-dependent attackers to read the contents of arbitrary memory locations via a crafted value of the third argument (aka the "bgd_color" or "clrBack" argument) for an indexed image.
Secunia reports:
Morgan Todd has discovered a vulnerability in AWStats, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed in the URL to awstats.pl is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Successful exploitation requires that the application is running as a CGI script.
Jan Lieskovsky reports:
perl-File-Path rmtree race condition (CVE-2005-0448 was assigned to address this)
This vulnerability was fixed in 5.8.4-7 but re-introduced in 5.8.8-1. It's also present in File::Path 2.xx, up to and including 2.07 which has only a partial fix.
Jan Minar reports:
Applying the ``D'' to a file with a crafted file name, or inside a directory with a crafted directory name, can lead to arbitrary code execution.
Lack of sanitization throughout Netrw can lead to arbitrary code execution upon opening a directory with a crafted name.
The Vim Netrw Plugin shares the FTP user name and password across all FTP sessions. Every time Vim makes a new FTP connection, it sends the user name and password of the previous FTP session to the FTP server.
CORE Security Technologies reports:
A format string error has been found on the vinagre_utils_show_error() function that can be exploited via commands issued from a malicious server containing format string specifiers on the VNC name.
In a web based attack scenario, the user would be required to connect to a malicious server. Successful exploitation would then allow the attacker to execute arbitrary code with the privileges of the Vinagre user.
Marc Schoenefeld and Steve Milner of RedHat SRT and Peter Allor of IBM ISS report:
XSS vulnerability with URLPARAM variable
SEARCH variable allows arbitrary shell command execution
Entry for CVE-2008-5619 says:
html2text.php in RoundCube Webmail (roundcubemail) 0.2-1.alpha and 0.2-3.beta allows remote attackers to execute arbitrary code via crafted input that is processed by the preg_replace function with the eval switch.
MySQL Team reports:
Additional corrections were made for the symlink-related privilege problem originally addressed. The original fix did not correctly handle the data directory pathname if it contained symlinked directories in its path, and the check was made only at table-creation time, not at table-opening time later.
A trapkit reports:
MPlayer contains a stack buffer overflow vulnerability while parsing malformed TwinVQ media files. The vulnerability may be exploited by a (remote) attacker to execute arbitrary code in the context of MPlayer.
Secunia reports:
A security issue has been reported in Ampache, which can be exploited by malicious, local users to perform certain actions with escalated privileges.
The security issue is caused due to the "gather-messages.sh" script handling temporary files in an insecure manner. This can be exploited via symlink attacks to overwrite arbitrary files with the privileges of the user running the script.
The Opera Team reports:
Manipulating certain text-area contents can cause a buffer overflow, which may be exploited to execute arbitrary code.
Certain HTML constructs can cause the resulting DOM to change unexpectedly, which triggers a crash. To inject code, additional techniques will have to be employed.
Exceptionally long host names in file: URLs can cause a buffer overflow, which may be exploited to execute arbitrary code. Remote Web pages cannot refer to file: URLs, so successful exploitation involves tricking users into manually opening the exploit URL, or a local file that refers to it.
When Opera is previewing a news feed, some scripted URLs are not correctly blocked. These can execute scripts which are able to subscribe the user to any feed URL that the attacker chooses, and can also view the contents of any feeds that the user is subscribed to. These may contain sensitive information.
Built-in XSLT templates incorrectly handle escaped content and can cause it to be treated as markup. If a site accepts content from untrusted users, which it then displays using XSLT as escaped strings, this can allow scripted markup to be injected. The scripts will then be executed in the security context of that site.
The MediaWiki development team reports:
Certain unspecified input is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Certain unspecified input related to uploads is not properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when a malicious data is opened. Successful exploitation may require that uploads are enabled and the victim uses an Internet Explorer based browser.
Certain SVG scripts are not properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when a malicious data is opened. Successful exploitation may require that SVG uploads are enabled and the victim uses a browser supporting SVG scripting.
The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain operations when a logged in user visits a malicious site.
The Drupal Project reports:
The update system is vulnerable to Cross site request forgeries. Malicious users may cause the superuser (user 1) to execute old updates that may damage the database.
When an input format is deleted, not all existing content on a site is updated to reflect this deletion. Such content is then displayed unfiltered. This may lead to cross site scripting attacks when harmful tags are no longer stripped from 'malicious' content that was posted earlier.

Secunia reports:
Input passed via the HTTP "Host" header is not properly sanitised before being used. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site if malicious data is viewed.
Samba Team reports:
Samba 3.0.29 and beyond contain a change to deal with gcc 4 optimizations. Part of the change modified range checking for client-generated offsets of secondary trans, trans2 and nttrans requests. These requests are used to transfer arbitrary amounts of memory from clients to servers and back using small SMB requests and contain two offsets: One offset (A) pointing into the PDU sent by the client and one (B) to direct the transferred contents into the buffer built on the server side. While the range checking for offset (B) is correct, a cut and paste error lets offset (A) pass completely unchecked against overflow.
The buffers passed into trans, trans2 and nttrans undergo higher-level processing like DCE/RPC requests or listing directories. The missing bounds check means that a malicious client can make the server do this higher-level processing on arbitrary memory contents of the smbd process handling the request. It is unknown if that can be abused to pass arbitrary memory contents back to the client, but an important barrier is missing from the affected Samba versions.
Secunia reports:
A security issue has been reported in hplip, which can be exploited by malicious, local users to cause a DoS.
The security issue is caused due to an error within hpssd.py when parsing certain requests. This can be exploited to crash the service by sending specially crafted requests to the default port 2207/TCP.

Secunia reports:
A vulnerability has been discovered in imlib2, which can be exploited by malicious people to potentially compromise an application using the library.
The vulnerability is caused due to a pointer arithmetic error within the "load()" function provided by the XPM loader. This can be exploited to cause a heap-based buffer overflow via a specially crafted XPM file.
Successful exploitation may allow execution of arbitrary code.

A boundary error exists within http_get_m3u() in lib/http.c when parsing a specially crafted m3u playlist containing an overly long "File" entry.
The mantis Team reports:
When configuring a web application to use only ssl (e. g. by forwarding all http-requests to https), a user would expect that sniffing and hijacking the session is impossible. Though, for this to be secure, one needs to set the session cookie to have the secure flag. Else the cookie will be transferred through http if the victim's browser does a single http-request on the same domain.

Successful exploitation may allow execution of arbitrary code, but requires e.g. that the user is tricked into processing an overly large XML file (2GB or more).
2) An integer overflow error in the "xmlBufferResize()" function can be exploited to trigger the execution of an infinite loop. The vulnerabilities are reported in version 2.7.2.
Other versions may also be affected.
Andreas Kurtz reports:
The jabber server Openfire (<= version 3.6.0a) contains several serious vulnerabilities. Depending on the particular runtime environment these issues can potentially even be used by an attacker to execute code on operating system level.
- Authentication bypass - This vulnerability provides an attacker full access to all functions in the admin webinterface without providing any user credentials. The Tomcat filter which is responsible for authentication could be completely circumvented.
- SQL injection - It is possible to pass SQL statements to the backend database through a SQL injection vulnerability. Depending on the particular runtime environment and database permissions it is even possible to write files to disk and execute code on operating system level.
- Multiple Cross-Site Scripting - Permits arbitrary insertion of HTML- and JavaScript code in login.jsp. An attacker could also manipulate a parameter to specify a destination to which a user will be forwarded to after successful authentication.
Florian Grandel reports:
I have not had the time to analyze all of syslog-ng code. But by reading the code section near the chroot call and looking at strace results I believe that syslog-ng does not chdir to the chroot jail's location before chrooting into it.
This opens up ways to work around the chroot jail.
Ulf Harnhammar of Secunia Research reports:
Stack-based buffer overflow in the read_special_escape function in src/psgen.c in GNU Enscript 1.6.1 and 1.6.4 beta, when the -e (aka special escapes processing) option is enabled, allows user-assisted remote attackers to execute arbitrary code via a crafted ASCII file, related to the setfilename command.
SecurityFocus reports:
GnuTLS is prone to a security-bypass vulnerability because the application fails to properly validate chained X.509 certificates. Successfully exploiting this issue allows attackers to perform man-in-the-middle attacks by impersonating trusted servers. Unsuspecting users may be under a false sense of security that can aid attackers in launching further attacks.
Wes Hardaker reports through sourceforge.net forum:
SECURITY ISSUE: A bug in the getbulk handling code could let anyone with even minimal access crash the agent. If you have open access to your snmp agents (bad bad bad; stop doing that!) or if you don't trust everyone that does have access to your agents you should updated immediately to prevent potential denial of service attacks.
Description at cve.mitre.org additionally clarifies:
Integer overflow in the netsnmp_create_subtree_cache function in agent/snmp_agent.c in net-snmp 5.4 before 5.4.2.1, 5.3 before 5.3.2.3, and 5.2 before 5.2.5.1 allows remote attackers to cause a denial of service (crash) via a crafted SNMP GETBULK request, which triggers a heap-based buffer overflow, related to the number of responses or repeats.

CVE reports:
Heap-based buffer overflow in the decodeMP4file function (frontend/main.c) in FAAD2 2.6.1 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted MPEG-4 (MP4) file.
Emacs developers report:
The Emacs command `run-python' launches an interactive Python interpreter. After the Python process starts up, Emacs automatically sends it the line:
import emacs
which normally imports a script named emacs.py which is distributed with Emacs. This script, which is typically located in a write-protected installation directory with other Emacs program files, defines various functions to help the Python process communicate with Emacs.
The vulnerability arises because Python, by default, prepends '' to the module search path, so modules are looked for in the current directory. If the current directory is world-writable, an attacker may insert malicious code by adding a fake Python module named emacs.py into that directory.
Advisory from Moritz Jodeit, November 8th, 2008:
ClamAV contains an off-by-one heap overflow vulnerability in the code responsible for parsing VBA project files. Successful exploitation could allow an attacker to execute arbitrary code with the privileges of the `clamd' process by sending an email with a prepared attachment.
A VBA project file embedded inside an OLE2 office document send as an attachment can trigger the off-by-one.

The VLC Team reports:
The VLC media player contains a stack overflow vulnerability while parsing malformed cue files. The vulnerability may be exploited by a (remote) attacker to execute arbitrary code in the context of VLC media player.
Opera reports:
When certain parameters are passed to Opera's History Search, they can cause content not to be correctly sanitized. This can allow scripts to be injected into the History Search results page. Such scripts can then run with elevated privileges and interact with Opera's configuration, allowing them to execute arbitrary code.
The links panel shows links in all frames on the current page, including links with JavaScript URLs. When a page is held in a frame, the script is incorrectly executed on the outermost page, not the page where the URL was located. This can be used to execute scripts in the context of an unrelated frame, which allows cross-site scripting.
Aurelien Jarno reports:
CVE-2008-4539: fix a heap overflow in Cirrus emulation
The code in hw/cirrus_vga.c has changed a lot between CVE-2007-1320 has been announced and the patch has been applied. As a consequence it has wrongly applied and QEMU is still vulnerable to this bug if using VNC.
SecurityFocus reports:
phpMyAdmin is prone to a cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied data.
An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.
Opera reports:
Certain constructs are not escaped correctly by Opera's History Search results. These can be used to inject scripts into the page, which can then be used to look through the user's browsing history, including the contents of the pages they have visited. These may contain sensitive information.
If a link that uses a JavaScript URL triggers Opera's Fast Forward feature, when the user activates Fast Forward, the script should run on the current page. When a page is held in a frame, the script is incorrectly executed on the outermost page, not the page where the URL was located. This can be used to execute scripts in the context of an unrelated frame, which allows cross-site scripting.
When Opera is previewing a news feed, some scripts are not correctly blocked. These scripts are able to subscribe the user to any feed URL that the attacker chooses, and can also view the contents of any feeds that the user is subscribed to. These may contain sensitive information.
CVE reports:
Heap-based buffer overflow in the SPF_dns_resolv_lookup function in Spf_dns_resolv.c in libspf2 before 1.2.8 allows remote attackers to execute arbitrary code via a long DNS TXT record with a modified length field.
Secunia reports:
OpenX can be exploited by malicious people to conduct SQL injection attacks.
Input passed to the "bannerid" parameter in www/delivery/ac.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The Flyspray Project reports:
Flyspray is affected by a Cross Site scripting Vulnerability due to an error escaping PHP's $_SERVER['QUERY_STRING'] superglobal, that can be maliciously used to inject arbitrary code into the savesearch() javascript function.
There is an XSS problem in the history tab, the application fails to sanitize the "details" parameter correctly, leading to the possibility of arbitrary code injection into the getHistory() javascript function.
Flyspray is affected by a Cross Site scripting Vulnerability due missing escaping of SQL error messages. By including HTML code in a query and at the same time causing it to fail by submitting invalid data, an XSS hole can be exploited.
There is an XSS problem in the task history attached to comments, since the application fails to sanitize the old_value and new_value database fields for changed task summaries.
Input passed via the "item_summary" parameter to "index.php?do=details" is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The Wordpress development team reports:
A vulnerability in the Snoopy library was announced today. WordPress uses Snoopy to fetch the feeds shown in the Dashboard. Although this seems to be a low risk vulnerability for WordPress users, we wanted to get an update out immediately.
The Drupal Project reports:
On a server configured for IP-based virtual hosts, Drupal may be caused to include and execute specifically named files outside of its root directory. This bug affects both Drupal 5 and Drupal 6.
The title of book pages is not always properly escaped, enabling users with the "create book content" permission or the permission to edit any node in the book hierarchy to insert arbitrary HTML and script code into pages. Such a Cross site scripting attack may lead to the attacker gaining administrator access. This bug affects Drupal 6.
xine team reports:
A new xine-lib version is now available. This release contains some security fixes, notably a DoS via corrupted Ogg files (CVE-2008-3231), some related fixes, and fixes for a few possible buffer overflows.
Adobe Product Security Incident Response Team reports:
Potential vulnerabilities have been identified in Adobe Flash Player 9.0.124.0 and earlier that could allow an attacker who successfully exploits these potential vulnerabilities to bypass Flash Player security controls. Adobe recommends users update to the most current version of Flash Player available for their platform.
Secunia reports:
Two vulnerabilities have been reported in Libxml2, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise an application using the library.
1) A recursion error exists when processing certain XML content. This can be exploited to e.g. exhaust all available memory and CPU resources by tricking an application using Libxml2 into processing specially crafted XML documents.
2) A boundary error in the processing of long XML entity names in parser.c can be exploited to cause a heap-based buffer overflow when specially crafted XML content is parsed.
Successful exploitation may allow execution of arbitrary code.
The Drupal Project reports:
A logic error in the core upload module validation allowed unprivileged users to attach files to content. Users can view files attached to content which they do not otherwise have access to. If the core upload module is not enabled, your site will not be affected.
A deficiency in the user module allowed users who had been blocked by access rules to continue logging into the site under certain conditions. If you do not use the 'access rules' functionality in core, your site will not be affected.
The BlogAPI module does not implement correct validation for certain content fields, allowing for values to be set for fields which would otherwise be inaccessible on an internal Drupal form. We have hardened these checks in BlogAPI module for this release, but the security team would like to re-iterate that the 'Administer content with BlogAPI' permission should only be given to trusted users. If the core BlogAPI module is not enabled, your site will not be affected.
A weakness in the node module API allowed for node validation to be bypassed in certain circumstances for contributed modules implementing the API. Additional checks have been added to ensure that validation is performed in all cases. This vulnerability only affects sites using one of a very small number of contributed modules, all of which will continue to work correctly with the improved API. None of them were found vulnerable, so our correction is a preventative measure.
The release note of cups 1.3.9 reports:
It contains the following fixes:
- SECURITY: The HP-GL/2 filter did not range check pen numbers (STR #2911)
- SECURITY: The SGI image file reader did not range check 16-bit run lengths (STR #2918)
- SECURITY: The text filter did not range check cpi, lpi, or column values (STR #2919)
Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the affected service.
Opera reports:
If a malicious page redirects Opera to a specially crafted address (URL), it can cause Opera to crash. Given sufficient address content, the crash could cause execution of code controlled by the attacking page.
Once a Java applet has been cached, if a page can predict the cache path for that applet, it can load the applet from the cache, causing it to run in the context of the local machine. This allows it to read other cache files on the computer or perform other normally more restrictive actions. These files could contain sensitive information, which could then be sent to the attacker.
Thomas Henlich reports:
The mysql command-line client does not quote HTML special characters like < in its output. This allows an attacker who is able to write data into a table to hide or modify records in the output, and to inject potentially dangerous code, e. g. Javascript to perform cross-site scripting or cross-site request forgery attacks.
The oCERT team reports:
The MPlayer multimedia player suffers from a vulnerability which could result in arbitrary code execution and at the least, in unexpected process termination. Three integer underflows located in the Real demuxer code can be used to exploit a heap overflow, a specific video file can be crafted in order to make the stream_read function reading or writing arbitrary amounts of memory.
Lighttpd seurity annoucement:
lighttpd 1.4.19, and possibly other versions before 1.5.0, does not decode the url before matching against rewrite and redirect patterns, which allows attackers to bypass rewrites rules. this can be a security problem in certain configurations if these rules are used to hide certain urls.
lighttpd 1.4.19, and possibly other versions before 1.5.0, does not lowercase the filename after generating it from the url in mod_userdir on case insensitive (file)systems.
As other modules are case sensitive, this may lead to information disclosure; for example if one configured php to handle files ending on ".php", an attacker will get the php source with http://example.com/~user/file.PHP
lighttpd 1.4.19 does not always release a header if it triggered a 400 (Bad Request) due to a duplicate header.

Hanno Boeck reports:
When configuring a web application to use only ssl (e.g. by forwarding all http-requests to https), a user would expect that sniffing and hijacking the session is impossible.
Though, for this to be secure, one needs to set the session cookie to have the secure flag. Otherwise the cookie will be transferred through HTTP if the victim's browser does a single HTTP request on the same domain.
Squirrelmail does not set that flag. It is fixed in the 1.5 test versions, but current 1.4.15 is vulnerable.
Secunia reports:
The vulnerability is caused due to the application truncating an overly long FTP command, and improperly interpreting the remainder string as a new FTP command. This can be exploited to execute arbitrary FTP commands with the privileges of another user by e.g. tricking the user into following malicious link.
Secunia reports:
An error exists in the "PMA_escapeJsString()" function in libraries/js_escape.lib.php, which can be exploited to bypass certain filters and execute arbitrary HTML and script code in a user's browser session in context of an affected site when e.g. Microsoft Internet Explorer is used.
Secunia reports:
An error in the handing of ZIP archives with symbolic links can be exploited to disclose the contents of arbitrary files.
Input from uploaded Flash animations is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed.
A phpMyAdmin security announcement:
The server_databases.php script was vulnerable to an attack coming from a user who is already logged-on to phpMyAdmin, where he can execute shell code (if the PHP configuration permits commands like exec).
Th1nk3r reports:
The version of TWiki installed on the remote host allows access to the 'configure' script and fails to sanitize the 'image' parameter of that script of directory traversal sequences before returning the file contents when the 'action' parameter is set to 'image'. An unauthenticated attacker can leverage this issue to view arbitrary files on the remote host subject to the privileges of the web server user id. .

Some vulnerabilities have been reported in various Horde products, which can be exploited by malicious people to conduct script insertion attacks
Input via MIME attachment linking is not properly sanitised in the MIME library before being used. This can be exploited to execute arbitrary HTML and script code in a user's browser session if e.g. a malicious email is viewed.
Certain unspecified input in HTML messages is not properly sanitised before being used. This can be exploited to execute arbitrary HTML and script in a user's browser session if e.g. a malicious HTML email is viewed.
Secunia reports:
Some vulnerabilities have been reported in Python, where some have unknown impact and others can potentially be exploited by malicious people to cause a DoS (Denial of Service) or to compromise a vulnerable system.
Various integer overflow errors exist in core modules e.g. stringobject, unicodeobject, bufferobject, longobject, tupleobject, stropmodule, gcmodule, mmapmodule.
An integer overflow in the hashlib module can lead to an unreliable cryptographic digest results.
Integer overflow errors in the processing of unicode strings can be exploited to cause buffer overflows on 32-bit systems.
An integer overflow exists in the PyOS_vsnprintf() function on architectures that do not have a "vsnprintf()" function.
An integer underflow error in the PyOS_vsnprintf() function when passing zero-length strings can lead to memory corruption.
SecurityFocus reports:
MySQL is prone to a security-bypass vulnerability. An attacker can exploit this issue to overwrite existing table files in the MySQL data directory, bypassing certain security restrictions.
Jonathan Weiss reports, that it is possible to perform an SQL injection in Rails applications via not correctly sanitized :limit and :offset parameters. It is possible to change arbitrary values in affected tables or gain access to the sensitive data.
The Wordpress development team reports:
With open registration enabled, it is possible in WordPress versions 2.6.1 and earlier to craft a username such that it will allow resetting another users password to a randomly generated password. The randomly generated password is not disclosed to the attacker, so this problem by itself is annoying but not a security exploit. However, this attack coupled with a weakness in the random number seeding in mt_rand() could be used to predict the randomly generated password.
In case of an incoming ICMPv6 'Packet Too Big Message', there is an insufficient check on the proposed new MTU for a path to the destination.
When the kernel is configured to process IPv6 packets and has active IPv6 TCP sockets, a specifically crafted ICMPv6 'Packet Too Big Message' could cause the TCP stack of the kernel to panic.
Systems without INET6 / IPv6 support are not vulnerable and neither are systems which do not listen on any IPv6 TCP sockets and have no active IPv6 connections.
Filter ICMPv6 'Packet Too Big Messages' using a firewall, but this will at the same time break PMTU support for IPv6 connections.
Various user defined input such as mount points, devices, and mount options are prepared and passed as arguments to nmount(2) into the kernel. Under certain error conditions, user defined data will be copied into a stack allocated buffer stored in the kernel without sufficient bounds checking.
If the system is configured to allow unprivileged users to mount file systems, it is possible for a local adversary to exploit this vulnerability and execute code in the context of the kernel.
It is possible to work around this issue by allowing only privileged users to mount file systems by running the following sysctl(8) command:
# sysctl vfs.usermount=0
If a General Protection Fault happens on a FreeBSD/amd64 system while it is returning from an interrupt, trap or system call, the swapgs CPU instruction may be called one extra time when it should not resulting in userland and kernel state being mixed.
A local attacker can by causing a General Protection Fault while the kernel is returning from an interrupt, trap or system call while manipulating stack frames and, run arbitrary code with kernel privileges.
The vulnerability can be used to gain kernel / supervisor privilege. This can for example be used by normal users to gain root privileges, to break out of jails, or bypass Mandatory Access Control (MAC) restrictions.
No workaround is available, but only systems running the 64 bit FreeBSD/amd64 kernels are vulnerable.
Systems with 64 bit capable CPUs, but running the 32 bit FreeBSD/i386 kernel are not vulnerable.
The Opera Team reports:
Scripts are able to change the addresses of framed pages that come from the same site. Due to a flaw in the way that Opera checks what frames can be changed, a site can change the address of frames on other sites inside any window that it has opened. This allows sites to open pages from other sites, and display misleading information on them.
Custom shortcut and menu commands can be used to activate external applications. In some cases, the parameters passed to these applications are not prepared correctly, and may be created from uninitialized memory. These may be misinterpreted as additional parameters, and depending on the application, this could allow execution of arbitrary code.
Successful exploitation requires convincing the user to modify their shortcuts or menu files appropriately, pointing to an appropriate target application, then to activate that shortcut at an appropriate time. To inject code, additional means will have to be employed.
When insecure pages load content from secure sites into a frame, they can cause Opera to incorrectly report the insecure site as being secure. The padlock icon will incorrectly be shown, and the security information dialog will state that the connection is secure, but without any certificate information.
As a security precaution, Opera does not allow Web pages to link to files on the user's local disk. However, a flaw exists that allows Web pages to link to feed source files on the user's computer. Suitable detection of JavaScript events and appropriate manipulation can unreliably allow a script to detect the difference between successful and unsuccessful subscriptions to these files, to allow it to discover if the file exists or not. In most cases the attempt will fail.
It has been reported that when a user subscribes to a news feed using the feed subscription button, the page address can be changed. This causes the address field not to update correctly. Although this can mean that misleading information can be displayed in the address field, it can only leave the attacking page's address in the address bar, not a trusted third party address.
Secunia reports:
A vulnerability has been reported in GnuTLS, which can potentially be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to a use-after-free error when an application calls "gnutls_handshake()" for an already valid session and can potentially be exploited, e.g. during re-handshakes.
Joomla project reports:
A flaw in the reset token validation mechanism allows for non-validating tokens to be forged. This will allow an unauthenticated, unauthorized user to reset the password of the first enabled user (lowest id). Typically, this is an administrator user. Note, that changing the first users username may lessen the impact of this exploit (since the person who changed the password does not know the login associated with the new password). However, the only way to completely rectify the issue is to upgrade to 1.5.6 (or patch the /components/com_user/models/reset.php file).
NASA Goddard Space Flight Center reports:
The libraries for the scientific data file format, Common Data Format (CDF) version 3.2 and earlier, have the potential for a buffer overflow vulnerability when reading specially-crafted (invalid) CDF files. If successful, this could trigger execution of arbitrary code within the context of the CDF-reading program that could be exploited to compromise a system, or otherwise crash the program. While it's unlikely that you would open CDFs from untrusted sources, we recommend everyone upgrade to the latest CDF libraries on their systems, including the IDL and Matlab plugins. Most worrisome is any service that enables the general public to submit CDF files for processing.
The vulnerability is in the CDF library routines not properly checking the length tags on a CDF file before copying data to a stack buffer. Exploitation requires the user to explicitly open a specially-crafted file. CDF users should not open files from untrusted third parties until the patch is applied (and continue then to exercise normal caution for files from untrusted third parties).
The Drupal Project reports:
A bug in the output filter employed by Drupal makes it possible for malicious users to insert script code into pages (cross site scripting or XSS). A bug in the private filesystem trusts the MIME type sent by the browser, enabling malicious users with the ability to upload files to execute cross site scripting attacks.
The BlogAPI module does not validate the extension of uploaded files, enabling users with the "administer content with blog api" permission to upload harmful files. This bug affects both Drupal 5.x and 6.x.
Drupal forms contain a token to protect against cross site request forgeries (CSRF). The token may not be validated properly for cached forms and forms containing AHAH elements. This bug affects Drupal 6.x.
User access rules can be added or deleted upon accessing a properly formatted URL, making such modifications vulnerable to cross site request forgeries (CSRF). This may lead to unintended addition or deletion of an access rule when a sufficiently privileged user visits a page or site created by a malicious person. This bug affects both Drupal 5.x and 6.x.
The Upload module in Drupal 6 contains privilege escalation vulnerabilities for users with the "upload files" permission. This can lead to users being able to edit nodes which they are normally not allowed to, delete any file to which the webserver has sufficient rights, and download attachments of nodes to which they have no access. Harmful files may also be uploaded via cross site request forgeries (CSRF). These bugs affect Drupal 6.x.
The official ruby site reports:
Several vulnerabilities in safe level have been discovereds:.
- untrace_var is permitted at safe level 4;
- $PROGRAM_NAME may be modified at safe level 4;
- insecure methods may be called at safe level 1-3;
- syslog operations are permitted at safe level 4;
- dl doesn't check taintness, so it could allow attackers to call dangerous functions.

resolv.rb allow remote attackers to spoof DNS answers. This risk can be reduced by randomness of DNS transaction IDs and source ports.
A Bugzilla Security Advisory reports:
When importing bugs using importxml.pl, the --attach_path option can be specified, pointing to the directory where attachments to import are stored. If the XML file being read by importxml.pl contains a malicious
../relative_path/to/local_filenode, the script follows this relative path and attaches the local file pointed by it to the bug, making the file public. The security fix makes sure the relative path is always ignored.
James Yonan reports:
Security Fix - affects non-Windows OpenVPN clients running OpenVPN 2.1-beta14 through 2.1-rc8 (OpenVPN 2.0.x clients are NOT vulnerable nor are any versions of the OpenVPN server vulnerable).
An OpenVPN client connecting to a malicious or compromised server could potentially receive an "lladdr" or "iproute" configuration directive from the server which could cause arbitrary code execution on the client. A successful attack requires that (a) the client has agreed to allow the server to push configuration directives to it by including "pull" or the macro "client" in its configuration file, (b) the client succesfully authenticates the server, (c) the server is malicious or has been compromised and is under the control of the attacker, and (d) the client is running a non-Windows OS.
A phpMyAdmin security announcement:
A logged-in user, if abused into clicking a crafted link or loading an attack page, would create a database he did not intend to, or would change his connection character set.
The Drupal Project reports:
Free tagging taxonomy terms can be used to insert arbitrary script and HTML code (cross site scripting or XSS) on node preview pages. A successful exploit requires that the victim selects a term containing script code and chooses to preview the node. This issue affects Drupal 6.x only. Some values from OpenID providers are output without being properly escaped, allowing malicious providers to insert arbitrary script and HTML code (XSS) into user pages. This issue affects Drupal 6.x only. filter_xss_admin() has been hardened to prevent use of the object HTML tag in administrator input.
Translated strings (5.x, 6.x) and OpenID identities (6.x) are immediately deleted upon accessing a properly formatted URL, making such deletion vulnerable to cross site request forgeries (CSRF). This may lead to unintended deletion of translated strings or OpenID identities when a sufficiently privileged user visits a page or site created by a malicious person.
When contributed modules such as Workflow NG terminate the current request during a login event, user module is not able to regenerate the user's session. This may lead to a session fixation attack, when a malicious user is able to control another users' initial session ID. As the session is not regenerated, the malicious user may use the 'fixed' session ID after the victim authenticates and will have the same access. This issue affects both Drupal 5 and Drupal 6.
Schema API uses an inappropriate placeholder for 'numeric' fields enabling SQL injection when user-supplied data is used for such fields.This issue affects Drupal 6 only.
The BIND DNS implementation does not randomize the UDP source port when doing remote queries, and the query id alone does not provide adequate randomization.
The lack of source port randomization reduces the amount of data the attacker needs to guess in order to successfully execute a DNS cache poisoning attack. This allows the attacker to influence or control the results of DNS queries being returned to users from target systems.
Limiting the group of machines that can do recursive queries on the DNS server will make it more difficult, but not impossible, for this vulnerability to be exploited.
To limit the machines able to perform recursive queries, add an ACL in named.conf and limit recursion like the following:
acl example-acl {
192.0.2.0/24;
};
options {
recursion yes;
allow-recursion { example-acl; };
};
Felipe Andres Manzano reports:
The libpoppler pdf rendering library, can free uninitialized pointers, leading to arbitrary code execution. This vulnerability results from memory management bugs in the Page class constructor/destructor.
Pylons team reports:
The error.py controller uses paste.fileapp to serve the static resources to the browser. The default error.py controller uses os.path.join to combine the id from Routes with the media path. Routes prior to 1.8 double unquoted the PATH_INFO, resulting in FileApp returning files from the filesystem that can be outside of the intended media path directory.
An attacker can craft URL's which utilize the double escaping to pass in a name to the error.py controller which contains a leading slash thus escaping the intended media path and serving files from any location on the filesystem that the Pylons application has access to.
Secunia reports:
- An integer overflow error exists in the processing of PFB font files. This can be exploited to cause a heap-based buffer overflow via a PFB file containing a specially crafted "Private" dictionary table.
- An error in the processing of PFB font files can be exploited to trigger the "free()" of memory areas that are not allocated on the heap.
- An off-by-one error exists in the processing of PFB font files. This can be exploited to cause a one-byte heap-based buffer overflow via a specially crafted PFB file.
- An off-by-one error exists in the implementation of the "SHC" instruction while processing TTF files. This can be exploited to cause a one-byte heap-based buffer overflow via a specially crafted TTF file.
Successful exploitation of the vulnerabilities may allow execution of arbitrary code.
Matthias Andree reports:

Secunia report:
Some vulnerabilities have been reported in phpMyAdmin, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via unspecified parameters to files in /libraries is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Successful exploitation requires that "register_globals" is enabled and support for ".htaccess" files is disabled.
Apache HTTP server project reports:
The following potential security flaws are addressed:
- CVE-2008-2364: mod_proxy_http: Better handling of excessive interim responses from origin server to prevent potential denial of service and high memory usage. Reported by Ryujiro Shibuya.

According to Maksymilian Arciemowicz research,
it is possible to bypass security restrictions
of safe_mode
in various
functions via directory traversal vulnerability. The attacker
can use this attack to gain access to sensitive
information. Functions utilizing
expand_filepath()
may be affected.
It should be noted that this vulnerability is not
considered to be serious by the FreeBSD Security Team,
since safe_mode
and open_basedir
are insecure by design and should not be relied upon.
Rdancer.org reports:
Improper quoting in some parts of Vim written in the Vim Script can lead to arbitrary code execution upon opening a crafted file.

Multiple vulnerabilities in Ruby may lead to a denial of service (DoS) condition or allow execution of arbitrary code.
Matthias Andree reports:
Gunter Nau reported fetchmail crashing on some messages; further debugging by Petr Uzel and Petr Cerny at Novell/SUSE Czech Republic dug up that this happened when fetchmail was trying to print, in -v -v verbose level, headers exceeding 2048 bytes. In this situation, fetchmail would resize the buffer and fill in further parts of the message, but forget to reinitialize its va_list typed source pointer, thus reading data from a garbage address found on the stack at addresses above the function arguments the caller passed in; usually that would be the caller's stack frame.
Matthieu Herrb of X.Org reports:
Several vulnerabilities have been found in the server-side code of some extensions in the X Window System. Improper validation of client-provided data can cause data corruption.
Exploiting these overflows will crash the X server or, under certain circumstances allow the execution of arbitray machine code.
When the X server is running with root privileges (which is the case for the Xorg server and for most kdrive based servers), these vulnerabilities can thus also be used to raise privileges.
All these vulnerabilities, to be exploited successfully, require either an already established connection to a running X server (and normally running X servers are only accepting authenticated connections), or a shell access with a valid user on the machine where the vulnerable server is installed.
MoinMoin team reports:
A check in the userform processing was not working as expected and could be abused for ACL and superuser privilege escalation.
Secunia reports:
A vulnerability has been reported in the Courier Authentication Library, which can be exploited by malicious people to conduct SQL injection attacks.
Input passed via e.g. the username to the library is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code and e.g. potentially bypass authentication.
Successful exploitation requires that a MySQL database is used for authentication and that a Non-Latin character set is selected.
The ikiwiki development team reports:
Until version 2.48, ikiwiki stored passwords in cleartext in the userdb. That risks exposing all users' passwords if the file is somehow exposed. To pre-emtively guard against that, current versions of ikiwiki store password hashes (using Eksblowfish).
The ikiwiki development team reports:
This hole allowed ikiwiki to accept logins using empty passwords to openid accounts that didn't use a password.
Upgrading to a non-vulnerable ikiwiki version immediatly is recommended if your wiki allows both password and openid logins.
Adobe Product Security Incident Response Team reports:
An exploit appears to be taking advantage of a known vulnerability, reported by Mark Dowd of the ISS X-Force and wushi of team509, that was resolved in Flash Player 9.0.124.0 (CVE-2007-0071). This exploit does NOT appear to include a new, unpatched vulnerability as has been reported elsewhere - customers with Flash Player 9.0.124.0 should not be vulnerable to this exploit.
Secunia reports:
A vulnerability has been reported in Nagios, which can be exploited by malicious people to conduct cross-site scripting attacks.
Spamdyke Team reports:
Fixed smtp_filter() to reject the DATA command if no valid recipients have been specified. Otherwise, a specific scenario could result in every spamdyke installation being used as an open relay. If the remote server connects and gives one or more recipients that are rejected (for relaying or blacklisting), then gives the DATA command, spamdyke will ignore all other commands, assuming that message data is being transmitted. However, because all of the recipients were rejected, qmail will reject the DATA command. From that point on, the remote server can give as many recipients as it likes and spamdyke will ignore them all -- they will not be filtered at all. After that, the remote server can give the DATA command and send the actual message data. Because spamdyke is controlling relaying, the RELAYCLIENT environment variable is set and qmail won't check for relaying either. Thanks to Mirko Buffoni for reporting this one.
Nico Golde discovered that PeerCast, a P2P audio and video streaming server, is vulnerable to a buffer overflow in the HTTP Basic Authentication code, allowing a remote attacker to crash PeerCast or execure arbitrary code.
Red Hat reports:
Will Drewry of the Google Security Team reported several flaws in the way libvorbis processed audio data. An attacker could create a carefully crafted [Vorbis] audio file in such a way that it could cause an application linked with libvorbis to crash, or execute arbitrary code when it was opened.
Django project reports:
The Django administration application will, when accessed by a user who is not sufficiently authenticated, display a login form and ask the user to provide the necessary credentials before displaying the requested page. This form will be submitted to the URL the user attempted to access, by supplying the current request path as the value of the form's "action" attribute.
The value of the request path was not being escaped, creating an opportunity for a cross-site scripting (XSS) attack by leading a user to a URL which contained URL-encoded HTML and/or JavaScript in the request path.
Secunia reports:
A vulnerability has been reported in vorbis-tools, which can potentially be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an input validation error when processing Speex headers, which can be exploited via a specially crafted Speex stream containing a negative "modeID" field in the header.
Successful exploitation may allow execution of arbitrary code.
Secunia reports:
A vulnerability has been reported in QEMU, which can be exploited by malicious, local users to bypass certain security restrictions.
The vulnerability is caused due to the "drive_init()" function in vl.c determining the format of a disk from data contained in the disk's header. This can be exploited by a malicious user in a guest system to e.g. read arbitrary files on the host by writing a fake header to a raw formatted disk image.
Secunia reports:
A vulnerability has been reported in swfdec, which can be exploited by malicious people to disclose sensitive information.
The vulnerability is caused due to swfdec not properly restricting untrusted sandboxes from reading local files, which can be exploited to disclose the content of arbitrary local files by e.g. tricking a user into visiting a malicious website.
FrSIRT reports:
A vulnerability has been identified in mt-daapd which could be exploited by remote attackers to cause a denial of service or compromise an affected system. This issue is caused by a buffer overflow error in the ws_getpostvars() function when processing a negative Content-Length: header value, which could be exploited by remote unauthenticated attackers to crash an affected application or execute arbitrary code.
Secunia reports:
Two vulnerabilities have been reported in SDL_image, which can be exploited by malicious people to cause a Denial of Service or potentially compromise an application using the library.
A boundary error within the LWZReadByte() function in IMG_gif.c can be exploited to trigger the overflow of a static buffer via a specially crafted GIF file.
A boundary error within the "IMG_LoadLBM_RW()" function in IMG_lbm.c can be exploited to cause a heap-based buffer overflow via a specially crafted IFF ILBM file.
Secunia reports:
A vulnerability has been reported in GnuPG, which can potentially be exploited to compromise a vulnerable system.
The vulnerability is caused due to an error when importing keys with duplicated IDs. This can be exploited to cause a memory corruption when importing keys via --refresh-keys or --import.
Successful exploitation potentially allows execution of arbitrary code, but has not been proven yet.
Extmail team reports:
Emergency update #4 fixes a serious security vulnerability.
Successful exploit of this vulnerability would allow attacker to change user's password without knowing it by using specifically crafted HTTP request.
Secunia reports:
A vulnerability has been reported in Mailman, which can be exploited by malicious users to conduct script insertion attacks.
Certain input when editing the list templates and the list info attribute is not properly sanitised before being stored. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the malicious website is accessed.
Secunia reports:
The vulnerability is caused due to an error when attaching to a TTY via the -T command line switch. This can be exploited to execute arbitrary commands with the privileges of the user running mksh via characters previously written to the attached virtual console.
Hanno Boeck reports:
The installer of serendipity 1.3 has various Cross Site Scripting issues. This is considered low priority, as attack scenarios are very unlikely.
Various path fields are not escaped properly, thus filling them with javascript code will lead to XSS. MySQL error messages are not escaped, thus the database host field can also be filled with javascript.
In the referrer plugin of the blog application serendipity, the referrer string is not escaped, thus leading to a permanent XSS.
Mozilla Foundation reports:
Fixes for security problems in the JavaScript engine described in MFSA 2008-15 introduced a stability problem, where some users experienced crashes during JavaScript garbage collection. This is being fixed primarily to address stability concerns. We have no demonstration that this particular crash is exploitable but are issuing this advisory because some crashes of this type have been shown to be exploitable in the past.
Secunia reports:
Tavis Ormandy has reported a vulnerability in libpng, which can be exploited by malicious people to cause a Denial of Service, disclose potentially sensitive information, or potentially compromise an application using the library.
The vulnerability is caused due to the improper handling of PNG chunks unknown to the library. This can be exploited to trigger the use of uninitialized memory in e.g. a free() call via unknown PNG chunks having a length of zero.
Successful exploitation may allow execution of arbitrary code, but requires that the application calls the png_set_read_user_chunk_fn() function or the png_set_keep_unknown_chunks() function under specific conditions.
Secunia reports:
A vulnerability has been reported in Openfire, which can be exploited by malicious people to cause a Denial of Service.
The vulnerability is caused due to an unspecified error and can be exploited to cause a Denial of Service.
CVE reports:
Integer overflow in PHP 5.2.5 and earlier allows context-dependent attackers to cause a denial of service and possibly have unspecified other impact via a printf format parameter with a large width specifier, related to the php_sprintf_appendstring function in formatted_print.c and probably other functions for formatted strings (aka *printf functions).
Justin Ferguson reports:
Integer signedness error in the zlib extension module in Python 2.5.2 and earlier allows remote attackers to execute arbitrary code via a negative signed integer, which triggers insufficient memory allocation and a buffer overflow.
The PostgreSQL developers report:
PostgreSQL allows users to create indexes on the results of user-defined functions, known as "expression indexes". This provided two vulnerabilities to privilege escalation: (1) index functions were executed as the superuser and not the table owner during VACUUM and ANALYZE, and (2) that SET ROLE and SET SESSION AUTHORIZATION were permitted within index functions. Both of these holes have now been closed.
PostgreSQL allowed malicious users to initiate a denial-of-service by passing certain regular expressions in SQL queries. First, users could create infinite loops using some specific regular expressions. Second, certain complex regular expressions could consume excessive amounts of memory. Third, out-of-range backref numbers could be used to crash the backend.
DBLink functions combined with local trust or ident authentication could be used by a malicious user to gain superuser privileges. This issue has been fixed, and does not affect users who have not installed DBLink (an optional module), or who are using password authentication for local access. This same problem was addressed in the previous release cycle, but that patch failed to close all forms of the loophole.
A phpMyAdmin security announcement report:
It is possible to read the contents of any file that the web server's user can access. The exact mechanism to achieve this won't be disclosed. If a user can upload on the same host where phpMyAdmin is running a PHP script that can read files with the rights of the web server's user, the current advisory does not describe an additional threat.
A phpMyAdmin security announcement report:
phpMyAdmin saves sensitive information like the MySQL username and password and the Blowfish secret key in session data, which might be unprotected on a shared host.
xine Team reports:
A new xine-lib version is now available. This release contains a security fix (an unchecked array index that could allows remote attackers to execute arbitrary code via a header structure containing a negative offset, which is used to dereference a function pointer.)
Secunia reports:
Some vulnerabilities have been reported in ClamAV, which can be exploited by malicious people to cause a DoS (Denial of Service) or to compromise a vulnerable system.
1) A boundary error exists within the "cli_scanpe()" function in libclamav/pe.c. This can be exploited to cause a heap-based buffer overflow via a specially crafted "Upack" executable.
Successful exploitation allows execution of arbitrary code.
2) A boundary error within the processing of PeSpin packed executables in libclamav/spin.c can be exploited to cause a heap-based buffer overflow.
Successful exploitation may allow execution of arbitrary code.
3) An unspecified error in the processing of ARJ files can be exploited to hang ClamAV.
Secunia reports:
A vulnerability has been reported in lighttpd, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to lighttpd not properly clearing the OpenSSL error queue. This can be exploited to close concurrent SSL connections of lighttpd by terminating one SSL connection.
The ikiwiki development team reports:
Cross Site Request Forging could be used to construct a link that would change a logged-in user's password or other preferences if they clicked on the link. It could also be used to construct a link that would cause a wiki page to be modified by a logged-in user.
postfix-policyd-weight does not check for symlink for its working directory. If the working directory is not already setup by the super root, an unprivileged user can link it to another directories in the system. This results in ownership/permission changes on the target directory.
If the system random number generator can be predicted by its past output, then an attacker may spoof Recursor to accept mallicious data. This leads to DNS cache poisoning and client redirection.
Multiple local privilege escalation are found in the symlink verification code. An attacker may use it to run a PHP script with the victim's privilege. This attack is a little harder when suphp operates in paranoid mode. For suphp that runs in owner mode which is the default in ports, immediate upgrade to latest version is advised.
Opera Software reports of multiple security issues in Opera. All of them can lead to arbitrary code execution. Details are as the following:
The Mozilla Foundation reports of multiple security issues in Firefox, Seamonkey, and Thunderbird. Several of these issues can probably be used to run arbitrary code with the privilege of the user running the program.
- MFSA 2008-19 XUL popup spoofing variant (cross-tab popups)
- MFSA 2008-18 Java socket connection to any local port via LiveConnect
- MFSA 2008-17 Privacy issue with SSL Client Authentication
- MFSA 2008-16 HTTP Referrer spoofing with malformed URLs
- MFSA 2008-15 Crashes with evidence of memory corruption (rv:1.8.1.13)
- MFSA 2008-14 JavaScript privilege escalation and arbitrary code execution
Core Security Technologies reports:
A remote buffer overflow vulnerability found in a library used by both the SILC server and client to process packets containing cryptographic material may allow an un-authenticated client to executearbitrary code on the server with the privileges of the user account running the server, or a malicious SILC server to compromise client systems and execute arbitrary code with the privileges of the user account running the SILC client program.
SecurityFocus reports:
The 'bzip2' application is prone to a remote file-handling vulnerability because the application fails to properly handle malformed files.
Exploit attempts likely result in application crashes.
Ian Jackson reports on the debian-security mailinglist:
When a block device read or write request is made by the guest, nothing checks that the request is within the range supported by the backend, but the code in the backend typically assumes that the request is sensible.
Depending on the backend, this can allow the guest to read and write arbitrary memory locations in qemu, and possibly gain control over the qemu process, escaping from the emulation/virtualisation.
Dovecot reports:
Security hole in blocking passdbs (MySQL always. PAM, passwd and shadow if blocking=yes) where user could specify extra fields in the password. The main problem here is when specifying "skip_password_check" introduced in v1.0.11 for fixing master user logins, allowing the user to log in as anyone without a valid password.
The Mplayer team reports:
A buffer overflow was found in the code used to extract album titles from CDDB server answers. When parsing answers from the CDDB server, the album title is copied into a fixed-size buffer with insufficient size checks, which may cause a buffer overflow. A malicious database entry could trigger a buffer overflow in the program. That can lead to arbitrary code execution with the UID of the user running MPlayer.
A buffer overflow was found in the code used to escape URL strings. The code used to skip over IPv6 addresses can be tricked into leaving a pointer to a temporary buffer with a non-NULL value; this causes the unescape code to reuse the buffer, and may lead to a buffer overflow if the old buffer is smaller than required. A malicious URL string may be used to trigger a buffer overflow in the program, that can lead to arbitrary code execution with the UID of the user running MPlayer.
A buffer overflow was found in the code used to parse MOV file headers. The code read some values from the file and used them as indexes into as array allocated on the heap without performing any boundary check. A malicious file may be used to trigger a buffer overflow in the program. That can lead to arbitrary code execution with the UID of the user running MPlayer.
Chris Evans from the Google Security Team reports:
Severity: parsing of evil PostScript file will result in arbitrary code execution.
A stack-based buffer overflow in the zseticcspace() function in zicc.c allows remote arbitrary code execution via a malicious PostScript file (.ps) that contains a long Range array.
A phpMyAdmin security announcement report:
phpMyAdmin used the $_REQUEST superglobal as a source for its parameters, instead of $_GET and $_POST. This means that on most servers, a cookie with the same name as one of phpMyAdmin's parameters can interfere.
Another application could set a cookie for the root path "/" with a "sql_query" name, therefore overriding the user-submitted sql_query because by default, the $_REQUEST superglobal imports first GET, then POST then COOKIE data.
Mitigation factor
An attacker must trick the victim into visiting a page on the same web server where he has placed code that creates a malicious cookie.
PCRE developers report:
A character class containing a very large number of characters with codepoints greater than 255 (in UTF-8 mode, of course) caused a buffer overflow.
xine Team reports:
A new xine-lib version is now available. This release contains a security fix (array index vulnerability which may lead to a stack buffer overflow.

- Crashes with evidence of memory corruption (rv:1.8.1.12)
Secunia Advisory reports:
A vulnerability has been reported in OpenLDAP, which can be exploited by malicious users to cause a DoS (Denial of Service).
iDefense Security Advisory 02.12.08:
Remote exploitation of an integer overflow vulnerability in Clam AntiVirus' ClamAV, as included in various vendors' operating system distributions, allows attackers to execute arbitrary code with the privileges of the affected process.
The vulnerability exists within the code responsible for parsing and scanning PE files. While iterating through all sections contained in the PE file, several attacker controlled values are extracted from the file. On each iteration, arithmetic operations are performed without taking into consideration 32-bit integer wrap.
Since insufficient integer overflow checks are present, an attacker can cause a heap overflow by causing a specially crafted Petite packed PE binary to be scanned. This results in an exploitable memory corruption condition.
Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the process using libclamav. In the case of the clamd program, this will result in code execution with the privileges of the clamav user. Unsuccessful exploitation results in the clamd process crashing.
Disabling the scanning of PE files will prevent exploitation.
If using clamscan, this can be done by running clamscan with the '--no-pe' option.
If using clamdscan, set the 'ScanPE' option in the clamd.conf file to 'no'.
The cacti development team reports:
Multiple security vulnerabilities have been discovered in Cacti's web interface:
- XSS vulnerabilities
- Path disclosure vulnerabilities
- SQL injection vulnerabilities
- HTTP response splitting vulnerabilities
The ikiwiki development team reports:
The htmlscrubber did not block javascript in uris. This was fixed by adding a whitelist of valid uri types, which does not include javascript. Some urls specifyable by the meta plugin could also theoretically have been used to inject javascript; this was also blocked.
zenphoto project reports:
A new zenphoto version is now available. This release contains security fixes for HTML, XSS, and SQL injection vulnerabilities.
Greg Wilkins reports:
jetty allows remote attackers to bypass protection mechanisms and read the source of files via multiple '/' characters in the URI.
xine project reports:
A new xine-lib version is now available. This release contains a security fix (remotely-expoitable buffer overflow, CVE-2006-1664). (This is not the first time that that bug has been fixed...) It also fixes a few more recent bugs, such as the audio output problems in 1.1.9.
Matthieu Herrb of X.Org reports:
Several vulnerabilities have been identified in server code of the X window system caused by lack of proper input validation on user controlled data in various parts of the software, causing various kinds of overflows.
Exploiting these overflows will crash the X server or, under certain circumstances allow the execution of arbitray machine code.
When the X server is running with root privileges (which is the case for the Xorg server and for most kdrive based servers), these vulnerabilities can thus also be used to raise privileges.
All these vulnerabilities, to be exploited succesfully, require either an already established connection to a running X server (and normally running X servers are only accepting authenticated connections), or a shell access with a valid user on the machine where the vulnerable server is installed.
Gentoo reports:
A remote attacker could entice a user to install a specially crafted "rc" file to execute arbitrary code via long strings in the "Name" and "Comment" fields or via unspecified vectors involving the second vulnerability.
Nico Golde reports:
A local attacker could exploit this vulnerability to conduct symlink attacks to overwrite files with the privileges of the user running Claws Mail.
Secunia reports:
A vulnerability has been reported in IRC Services, which can be exploited by malicious people to cause a Denial of Service. The vulnerability is caused due to the improper handling of overly long passwords within the "default_encrypt()" function in encrypt.c and can be exploited to crash an affected server.
xine project reports:
A new xine-lib version is now available. This release contains a security fix (remotely-expoitable buffer overflow, CVE-2008-0225). It also contains a read-past-end fix for an internal library function which is only used if the OS does not supply it and a rendering fix for Darwin/PPC.
Geeklog reports:
MustLive pointed out a possible XSS in the form to email an article to a friend that we're fixing with this release.
Please note that this problem only exists in Geeklog 1.4.0 - neither Geeklog 1.4.1 nor any older versions (1.3.x series) have that problem.
The Drupal Project reports:
The aggregator module fetches items from RSS feeds and makes them available on the site. The module provides an option to remove items from a particular feed. This has been implemented as a simple GET request and is therefore vulnerable to cross site request forgeries. For example: Should a privileged user view a page containing an <img> tag with a specially constructed src pointing to a remove items URL, the items would be removed.
The Drupal Project reports:
When outputting plaintext Drupal strips potentially dangerous HTML tags and attributes from HTML, and escapes characters which have a special meaning in HTML. This output filtering secures the site against cross site scripting attacks via user input.
Certain byte sequences that are invalid in the UTF8 specification are not handled properly by Internet Explorer 6 and may lead it to see a multibyte start character where none is present. Internet Explorer 6 then consumes a number of subsequent UTF-8 characters. This may lead to unsafe attributes that were outside a tag for the filter to appear inside a tag for Internet Explorer 6. This behaviour can then be used to insert and execute javascript in the context of the website.
The Drupal Project reports:
When theme .tpl.php files are accessible via the web and the PHP setting register_globals is set to enabled, anonymous users are able to execute cross site scripting attacks via specially crafted links.
Drupal's .htaccess attempts to set register_globals to disabled and also prevents access to .tpl.php files. Only when both these measures are not effective and your PHP interpreter is configured with register_globals set to enabled, will this issue affect you.
Secunia reports:
A vulnerability has been reported in MaraDNS, which can be exploited by malicious people to cause a Denial of Service.
The vulnerability is caused due to an error within the handling of certain DNS packets. This can be exploited to cause a resource rotation by sending specially crafted DNS packets, which cause an authoritative CNAME record to not resolve, resulting in a Denial of Sevices.
Secunia reports:
Multiple vulnerabilities have been reported in RealPlayer/RealOne/HelixPlayer, which can be exploited by malicious people to compromise a user's system.
An input validation error when processing .RA/.RAM files can be exploited to cause a heap corruption via a specially crafted .RA/.RAM file with an overly large size field in the header.
An error in the processing of .PLS files can be exploited to cause a memory corruption and execute arbitrary code via a specially crafted .PLS file.
An input validation error when parsing .SWF files can be exploited to cause a buffer overflow via a specially crafted .SWF file with malformed record headers.
A boundary error when processing rm files can be exploited to cause a buffer overflow.
Adobe Security bulletin:
Critical vulnerabilities have been identified in Adobe Flash Player that could allow an attacker who successfully exploits these potential vulnerabilities to take control of the affected system. A malicious SWF must be loaded in Flash Player by the user for an attacker to exploit these potential vulnerabilities. Users are recommended to update to the most current version of Flash Player available for their platform.
Dovecot reports:
If two users with the same password and same pass_filter variables log in within auth_cache_ttl seconds (1h by default), the second user may get logged in with the first user's cached pass_attrs. For example if pass_attrs contained the user's home/mail directory, this would mean that the second user will be accessing the first user's mails.
The Gallery team reports:

- WebCam module - Fixed proxied request weakness.
Theodore Y. Ts'o reports:
Fix a potential security vulnerability where an untrusted filesystem can be corrupted in such a way that a program using libext2fs will allocate a buffer which is far too small. This can lead to either a crash or potentially a heap-based buffer overflow crash. No known exploits exist, but main concern is where an untrusted user who possesses privileged access in a guest Xen environment could corrupt a filesystem which is then accessed by thus allowing the untrusted user to gain privileged access in the host OS. Thanks to the McAfee AVERT Research group for reporting this issue.
The Wireshark team reports of multiple vulnerabilities:
- Wireshark could crash when reading an MP3 file.
- Beyond Security discovered that Wireshark could loop excessively while reading a malformed DNP packet.
- Stefan Esser discovered a buffer overflow in the SSL dissector.
- The ANSI MAP dissector could be susceptible to a buffer overflow on some platforms.
- The Firebird/Interbase dissector could go into an infinite loop or crash.
- The NCP dissector could cause a crash.
- The HTTP dissector could crash on some systems while decoding chunked messages.
- The MEGACO dissector could enter a large loop and consume system resources.
- The DCP ETSI dissector could enter a large loop and consume system resources.
- Fabiodds discovered a buffer overflow in the iSeries (OS/400) Communication trace file parser.
- The PPP dissector could overflow a buffer.
- The Bluetooth SDP dissector could go into an infinite loop.
- A malformed RPC Portmap packet could cause a crash.
- The IPv6 dissector could loop excessively.
- The USB dissector could loop excessively or crash.
- The SMB dissector could crash.
- The RPL dissector could go into an infinite loop.
- The WiMAX dissector could crash due to unaligned access on some platforms.
- The CIP dissector could attempt to allocate a huge amount of memory and crash.
Impact
It may be possible to make Wireshark or Ethereal crash or use up available memory by injecting a purposefully malformed packet onto the wire or by convincing someone to read a malformed packet trace file.
Opera Software ASA reports about multiple security fixes:
- Fixed an issue where plug-ins could be used to allow cross domain scripting, as reported by David Bloom. Details will be disclosed at a later date.
- Fixed an issue with TLS certificates that could be used to execute arbitrary code, as reported by Alexander Klink (Cynops GmbH). Details will be disclosed at a later date.
- Rich text editing can no longer be used to allow cross domain scripting, as reported by David Bloom. See our advisory.
- Prevented bitmaps from revealing random data from memory, as reported by Gynvael Coldwind. Details will be disclosed at a later date.
Luigi Auriemma reports that peercast is vulnerable to a buffer overflow which could lead to a DoS or potentially remote code execution:
The handshakeHTTP function which handles all the requests received by the other clients is vulnerable to a heap overflow which allows an attacker to fill the loginPassword and loginMount buffers located in the Servent class with how much data he wants.
The Ganglia project reports:
The Ganglia development team is pleased to release Ganglia 3.0.6 (Foss) which is available[...]. This release includes a security fix for web frontend cross-scripting vulnerability.
SecurityFocus reports:
QEMU is prone to a local denial-of-service vulnerability because it fails to perform adequate boundary checks when handling user-supplied input.
Attackers can exploit this issue to cause denial-of-service conditions. Given the nature of the issue, attackers may also be able to execute arbitrary code, but this has not been confirmed.
The Drupal Project reports:
The function taxonomy_select_nodes() directly injects variables into SQL queries instead of using placeholders. While taxonomy module itself validates the input passed to taxonomy_select_nodes(), this is a weakness in Drupal core. Several contributed modules, such as taxonomy_menu, ajaxLoader, and ubrowser, directly pass user input to taxonomy_select_nodes(), enabling SQL injection attacks by anonymous users.
Secuna Research reports:
Secunia Research has discovered a vulnerability in Samba, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to a boundary error within the "send_mailslot()" function. This can be exploited to cause a stack-based buffer overflow with zero bytes via a specially crafted "SAMLOGON" domain logon packet containing a username string placed at an odd offset followed by an overly long GETDC string. Successful exploitation allows execution of arbitrary code, but requires that the "domain logons" option is enabled.
Secunia reports:
Format string vulnerability in the SMBDirList function in dirlist.c in SmbFTPD 0.96 allows remote attackers to execute arbitrary code via format string specifiers in a directory name.
Cross-site scripting (XSS) vulnerability in Dump Servlet in Mortbay Jetty before 6.1.6rc1 allows remote attackers to inject arbitrary web script or HTML via unspecified parameters and cookies.
Mortbay Jetty before 6.1.6rc1 does not properly handle "certain quote sequences" in HTML cookie parameters, which allows remote attackers to hijack browser sessions via unspecified vectors.
CRLF injection vulnerability in Mortbay Jetty before 6.1.6rc0 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.
The live555 development team reports:
Fixed a bounds-checking error in "parseRTSPRequestString()" caused by an int vs. unsigned problem.
The function which handles the incoming queries from the clients is affected by a vulnerability which allows an attacker to crash the server remotely using the smallest RTSP query possible to use.
GNU security announcement:
GNU Finger unfortunately has not been updated in many years, and has known security vulnerabilities. Please do not use it in production environments.
Squid secuirty advisory reports:
Due to incorrect bounds checking Squid is vulnerable to a denial of service check during some cache update reply processing.
This problem allows any client trusted to use the service to perform a denial of service attack on the Squid service.
Rails core team reports:
The rails core team has released ruby on rails 1.2.6 to address a bug in the fix for session fixation attacks (CVE-2007-5380). The CVE Identifier for this new issue is CVE-2007-6077.
Rails core team reports:
All users of Rails 1.2.4 or earlier are advised to upgrade to 1.2.5, though it isn't strictly necessary if you aren't working with JSON. For more information the JSON vulnerability, see CVE-2007-3227.
The ikiwiki development team reports:
Ikiwiki did not check if path to the srcdir to contained a symlink. If an attacker had commit access to the directories in the path, they could change it to a symlink, causing ikiwiki to read and publish files that were not intended to be published. (But not write to them due to other checks.)
Mozilla Foundation reports:
The Firefox 2.0.0.10 update contains fixes for three bugs that improve the stability of the product. These crashes showed some evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code.
phpMyAdmin security announcement:
The login page auth_type cookie was vulnerable to XSS via the convcharset parameter. An attacker could use this to execute malicious code on the visitors computer
The Samba Team reports:
Secunia Research reported a vulnerability that allows for the execution of arbitrary code in nmbd. This defect may only be exploited when the "wins support" parameter has been enabled in smb.conf.
Samba developers have discovered what is believed to be a non-exploitable buffer over in nmbd during the processing of GETDC logon server requests. This code is only used when the Samba server is configured as a Primary or Backup Domain Controller.
PHP project reports:
Security Enhancements and Fixes in PHP 5.2.5:
- Fixed dl() to only accept filenames. Reported by Laurent Gaffie.
- Fixed dl() to limit argument size to MAXPATHLEN (CVE-2007-4887). Reported by Laurent Gaffie.
- Fixed htmlentities/htmlspecialchars not to accept partial multibyte sequences. Reported by Rasmus Lerdorf
- Fixed possible triggering of buffer overflows inside glibc implementations of the fnmatch(), setlocale() and glob() functions. Reported by Laurent Gaffie.
- Fixed "mail.force_extra_parameters" php.ini directive not to be modifiable in .htaccess due to the security implications. Reported by SecurityReason.
- Fixed bug #42869 (automatic session id insertion adds sessions id to non-local forms).
- Fixed bug #41561 (Values set with php_admin_* in httpd.conf can be overwritten with ini_set()).
US-CERT reports:
webserver.c in mt-dappd in Firefly Media Server 0.2.4 and earlier allows remote attackers to cause a denial of service (NULL dereference and daemon crash) via a stats method action to /xml-rpc with (1) an empty Authorization header line, which triggers a crash in the ws_decodepassword function; or (2) a header line without a ':' character, which triggers a crash in the ws_getheaders function.
CVE reports:
The SNMP agent (snmp_agent.c) in net-snmp before 5.4.1 allows remote attackers to cause a denial of service (CPU and memory consumption) via a GETBULK request with a large max-repeaters value.
iDefense Laps reports:
Remote exploitation of multiple integer overflow vulnerabilities in libFLAC, as included with various vendor's software distributions, allows attackers to execute arbitrary code in the context of the currently logged in user.
These vulnerabilities specifically exist in the handling of malformed FLAC media files. In each case, an integer overflow can occur while calculating the amount of memory to allocate. As such, insufficient memory is allocated for the data that is subsequently read in from the file, and a heap based buffer overflow occurs.
Secunia Research reports:
Secunia Research has discovered some vulnerabilities in Xpdf, which can be exploited by malicious people to compromise a user's system.
- An array indexing error within the "DCTStream::readProgressiveDataUnit()" method in xpdf/Stream.cc can be exploited to corrupt memory via a specially crafted PDF file.
- An integer overflow error within the "DCTStream::reset()" method in xpdf/Stream.cc can be exploited to cause a heap-based buffer overflow via a specially crafted PDF file.
- A boundary error within the "CCITTFaxStream::lookChar()" method in xpdf/Stream.cc can be exploited to cause a heap-based buffer overflow by tricking a user into opening a PDF file containing a specially crafted "CCITTFaxDecode" filter.
Successful exploitation may allow execution of arbitrary code.
Plone projectreports:
This hotfix corrects a vulnerability in the statusmessages and linkintegrity modules, where unsafe network data was interpreted as python pickles. This allows an attacker to run arbitrary python code within the Zope/Plone process.
The DigiTrust Group reports:
When creating a new database, a malicious user can use a client-side Web proxy to place malicious code in the db parameter of the POST request. Since db_create.php does not properly sanitize user-supplied input, an administrator could face a persistent XSS attack when the database names are displayed.
Gallery project reports:
Gallery 2.2.3 addresses the following security vulnerabilities:
- Unauthorized renaming of items possible with WebDAV (reported by Merrick Manalastas)
- Unauthorized modification and retrieval of item properties possible with WebDAV
- Unauthorized locking and replacing of items possible with WebDAV
- Unauthorized editing of data file possible via linked items with Reupload and WebDAV (reported by Nicklous Roberts)
Secunia reports:
Some vulnerabilities have been reported in TikiWiki, which can be exploited by malicious people to conduct cross-site scripting and script insertion attacks and disclose potentially sensitive information.
Input passed to the username parameter in tiki-remind_password.php (when remind is set to send me my password) is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code (for example with meta refreshes to a javascript: URL) in a user's browser session in context of an affected site.
Input passed to the local_php and error_handler parameters in tiki-index.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.
Input passed to the imp_language parameter in tiki-imexport_languages.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.
Certain img src elements are not properly santised before being used. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed.
Secunia reports:
Secunia Research has discovered a vulnerability in CUPS, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the "ippReadIO()" function in cups/ipp.c when processing IPP (Internet Printing Protocol) tags. This can be exploited to overwrite one byte on the stack with a zero by sending an IPP request containing specially crafted "textWithLanguage" or "nameWithLanguage" tags.
Successful exploitation allows execution of arbitrary code.
Red Hat reports:
A flaw was found in Perl's regular expression engine. Specially crafted input to a regular expression can cause Perl to improperly allocate memory, possibly resulting in arbitrary code running with the permissions of the user running Perl.
Debian project reports:
Tavis Ormandy of the Google Security Team has discovered several security issues in PCRE, the Perl-Compatible Regular Expression library, which potentially allow attackers to execute arbitrary code by compiling specially crafted regular expressions.
SEC-Consult reports:
Perdition IMAP is affected by a format string bug in one of its IMAP output-string formatting functions. The bug allows the execution of arbitrary code on the affected server. A successful exploit does not require prior authentication.
Gentoo reports:
Kalle Olavi Niemitalo discovered two boundary errors in fsplib code included in gFTP when processing overly long directory or file names.
A remote attacker could trigger these vulnerabilities by enticing a user to download a file with a specially crafted directory or file name, possibly resulting in the execution of arbitrary code or a Denial of Service.
Securiweb reports:
dircproxy allows remote attackers to cause a denial of service (segmentation fault) via an ACTION command without a parameter, which triggers a NULL pointer dereference, as demonstrated using a blank /me message from irssi.
A Secunia Advisory report:
Input passed to the "posts_columns" parameter in wp-admin/edit-post-rows.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
BugTraq reports:
OpenLDAP is prone to multiple remote denial-of-service vulnerabilities because of an incorrect NULL-termination issue and a double-free issue.
Django project reports:
A per-process cache used by Django's internationalization ("i18n") system to store the results of translation lookups for particular values of the HTTP Accept-Language header used the full value of that header as a key. An attacker could take advantage of this by sending repeated requests with extremely large strings in the Accept-Language header, potentially causing a denial of service by filling available memory.
Due to limitations imposed by Web server software on the size of HTTP header fields, combined with reasonable limits on the number of requests which may be handled by a single server process over its lifetime, this vulnerability may be difficult to exploit. Additionally, it is only present when the "USE_I18N" setting in Django is "True" and the i18n middleware component is enabled*. Nonetheless, all users of affected versions of Django are encouraged to update.
An advisory from Opera reports:
If a user has configured Opera to use an external newsgroup client or e-mail application, specially crafted Web pages can cause Opera to run that application incorrectly. In some cases this can lead to execution of arbitrary code.
When accesing frames from different Web sites, specially crafted scripts can bypass the same-origin policy, and overwrite functions from those frames. If scripts on the page then run those functions, this can cause the script of the attacker's choice to run in the context of the target Web site.
The Drupal Project reports:
In some circumstances Drupal allows user-supplied data to become part of response headers. As this user-supplied data is not always properly escaped, this can be exploited by malicious users to execute HTTP response splitting attacks which may lead to a variety of issues, among them cache poisoning, cross-user defacement and injection of arbitrary code.
The Drupal installer allows any visitor to provide credentials for a database when the site's own database is not reachable. This allows attackers to run arbitrary code on the site's server. An immediate workaround is the removal of the file install.php in the Drupal root directory.
The allowed extension list of the core Upload module contains the extension HTML by default. Such files can be used to execute arbitrary script code in the context of the affected site when a user views the file. Revoking upload permissions or removing the .html extension from the allowed extension list will stop uploads of malicious files. but will do nothing to protect your site againstfiles that are already present. Carefully inspect the file system path for any HTML files. We recommend you remove any HTML file you did not update yourself. You should look for , CSS includes, Javascript includes, and onerror="" attributes if you need to review files individually.
The Drupal Forms API protects against cross site request forgeries (CSRF), where a malicious site can cause a user to unintentionally submit a form to a site where he is authenticated. The user deletion form does not follow the standard Forms API submission model and is therefore not protected against this type of attack. A CSRF attack may result in the deletion of users.
The publication status of comments is not passed during the hook_comments API operation, causing various modules that rely on the publication status (such as Organic groups, or Subscriptions) to mail out unpublished comments.
Ganael Laplanche reports:
Up to now, each ldap* command was called with the -w parameter, which allows to specify the bind password on the command line. Unfortunately, this could make the password appear to anybody performing a `ps` during the call. This is now avoided by using the -y parameter and a password file.
RedHat reports:
Several flaws were found in the way in which Firefox displayed malformed web content. A web page containing specially-crafted content could potentially trick a user into surrendering sensitive information. (CVE-2007-1095, CVE-2007-3844, CVE-2007-3511, CVE-2007-5334)
The DigiTrust Group discovered serious XSS vulnerability in the phpMyAdmin server_status.php script. According to their report
vulnerability can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
SecurityFocus reports:
phpMyAdmin is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input.
An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal potentially sensitive information and launch other attacks.
A Secunia Advisory reports:
The vulnerability is caused due to a boundary error within the redir() function in check_http.c when processing HTTP Location: header information. This can be exploited to cause a buffer overflow by returning an overly long string in the "Location:" header to a vulnerable system.
A Secunia Advisory reports:
Some vulnerabilities have been reported in libpng, which can be exploited by malicious people to cause a DoS (Denial of Service).
Certain errors within libpng, including a logical NOT instead of a bitwise NOT in pngtrtran.c, an error in the 16bit cheap transparency extension, and an incorrect use of sizeof() may be exploited to crash an application using the library.
Various out-of-bounds read errors exist within the functions png_handle_pCAL(), png_handle_sCAL(), png_push_read_tEXt(), png_handle_iTXt(), and png_handle_ztXt(), which may be exploited by exploited to crash an application using the library.
The vulnerability is caused due to an off-by-one error within the ICC profile chunk handling, which potentially can be exploited to crash an application using the library.
Multiple vulnerabilities have been discovered in ImageMagick.
ImageMagick before 6.3.5-9 allows context-dependent attackers to cause a denial of service via a crafted image file that triggers (1) an infinite loop in the ReadDCMImage function, related to ReadBlobByte function calls; or (2) an infinite loop in the ReadXCFImage function, related to ReadBlobMSBLong function calls.
Multiple integer overflows in ImageMagick before 6.3.5-9 allow context-dependent attackers to execute arbitrary code via a crafted (1) .dcm, (2) .dib, (3) .xbm, (4) .xcf, or (5) .xwd image file, which triggers a heap-based buffer overflow.
Off-by-one error in the ReadBlobString function in blob.c in ImageMagick before 6.3.5-9 allows context-dependent attackers to execute arbitrary code via a crafted image file, which triggers the writing of a '\0' character to an out-of-bounds address.
Sign extension error in the ReadDIBImage function in ImageMagick before 6.3.5-9 allows context-dependent attackers to execute arbitrary code via a crafted width value in an image file, which triggers an integer overflow and a heap-based buffer overflow.
SUN reports:
A vulnerability in the Java Runtime Environment (JRE) with applet caching may allow an untrusted applet that is downloaded from a malicious website to make network connections to network services on machines other than the one that the applet was downloaded from. This may allow network resources (such as web pages) and vulnerabilities (that exist on these network services) which are not otherwise normally accessible to be accessed or exploited.
Matthieu Herrb reports:
Problem Description:
Several vulnerabilities have been identified in xfs, the X font server. The QueryXBitmaps and QueryXExtents protocol requests suffer from lack of validation of their 'length' parameters.
Impact:
On most modern systems, the font server is accessible only for local clients and runs with reduced privileges, but on some systems it may still be accessible from remote clients and possibly running with root privileges, creating an opportunity for remote privilege escalation.
A Buffer overflow in the ReadImage function in generic/tkImgGIF.c in Tcl/Tk, allows remote attackers to execute arbitrary code via multi-frame interlaced GIF files in which later frames are smaller than the first.
RISE Security reports:
There exists multiple vulnerabilities within functions of Firebird Relational Database, which when properly exploited can lead to remote compromise of the vulnerable system.
Debian Bug report log reports:
When tagging file $foo, a temporary copy of the file is created, and for some reason, libid3 doesn't use mkstemp but just creates $foo.XXXXXX literally, without any checking.
This would silently truncate and overwrite an existing $foo.XXXXXX.
The MediaWiki development team reports:
A possible HTML/XSS injection vector in the API pretty-printing mode has been found and fixed.
The vulnerability may be worked around in an unfixed version by simply disabling the API interface if it is not in use, by adding this to LocalSettings.php:
$wgEnableAPI = false;
(This is the default setting in 1.8.x.)
Alexander Concha reports:
While testing WordPress, it has been discovered a SQL Injection vulnerability that allows an attacker to retrieve remotely any user credentials from a vulnerable site, this bug is caused because of early database escaping and the lack of validation in query string like parameters.
The Samba development team reports:
The idmap_ad.so library provides an nss_info extension to Winbind for retrieving a user's home directory path, login shell and primary group id from an Active Directory domain controller. This functionality is enabled by defining the "winbind nss info" smb.conf option to either "sfu" or "rfc2307".
Both the Windows "Identity Management for Unix" and "Services for Unix" MMC plug-ins allow a user to be assigned a primary group for Unix clients that differs from the user's Windows primary group. When the rfc2307 or sfu nss_info plugin has been enabled, in the absence of either the RFC2307 or SFU primary group attribute, Winbind will assign a primary group ID of 0 to the domain user queried using the getpwnam() C library call.
A Bugzilla Security Advisory reports:
This advisory covers three security issues that have recently been fixed in the Bugzilla code:
- A possible cross-site scripting (XSS) vulnerability when filing bugs using the guided form.
- When using email_in.pl, insufficiently escaped data may be passed to sendmail.
- Users using the WebService interface may access Bugzilla's time-tracking fields even if they normally cannot see them.
We strongly advise that 2.20.x and 2.22.x users should upgrade to 2.20.5 and 2.22.3 respectively. 3.0 users, and users of 2.18.x or below, should upgrade to 3.0.1.
BugTraq reports:
ClamAV is prone to multiple denial-of-service vulnerabilities.
A successful attack may allow an attacker to crash the application and deny service to users.
The coppermine development team reports two vulnerabilities with the coppermine application. These vulnerabilities are caused by improper checking of the log variable in "viewlog.php" and improper checking of the referer variable in "mode.php". This could allow local file inclusion, potentially disclosing valuable information and could lead to an attacker conducting a cross site scripting attack against the targeted site.
iDefense reports:
Remote exploitation of multiple integer overflow vulnerabilities within OpenOffice, as included in various vendors' operating system distributions, allows attackers to execute arbitrary code.
These vulnerabilities exist within the TIFF parsing code of the OpenOffice suite. When parsing the TIFF directory entries for certain tags, the parser uses untrusted values from the file to calculate the amount of memory to allocate. By providing specially crafted values, an integer overflow occurs in this calculation. This results in the allocation of a buffer of insufficient size, which in turn leads to a heap overflow.
The Bugzilla development team reports:
Bugzilla::WebService::User::offer_account_by_email does not check the "createemailregexp" parameter, and thus allows users to create accounts who would normally be denied account creation. The "emailregexp" parameter is still checked. If you do not have the SOAP::Lite Perl module installed on your Bugzilla system, your system is not vulnerable (because the Bugzilla WebService will not be enabled).
The KDE development team reports:
The Konqueror address bar is vulnerable to spoofing attacks that are based on embedding white spaces in the url. In addition the address bar could be tricked to show an URL which it is intending to visit for a short amount of time instead of the current URL.
The KDE development team reports:
KDM can be tricked into performing a password-less login even for accounts with a password set under certain circumstances, namely autologin to be configured and "shutdown with password" enabled.
The Flyspray Project reports:
Flyspray authentication system can be bypassed by sending a carefully crafted post request.
To be vulnerable, PHP configuration directive output_buffering has to be disabled or set to a low value.
The Mozilla Foundation reports a vulnerability within the mozilla browser. This vulnerability also affects various other browsers like firefox and seamonkey. The vulnerability is caused by QuickTime Media-Link files that contain a qtnext attribute. This could allow an attacker to start the browser with arbitrary command-line options. This could allow the attacker to install malware, steal local data and possibly execute and/or do other arbitrary things within the users context.

lighttpd maintainer reports:
Lighttpd is prone to a header overflow when using the mod_fastcgi extension, this can lead to arbitrary code execution in the fastcgi application. For a detailed description of the bug see the external reference.
This bug was found by Mattias Bengtsson and Philip Olausson
Gentoo reports:
Sune Kloppenborg Jeppesen and Tavis Ormandy of the Gentoo Linux Security Team have reported that the check_update.sh script and the main rkhunter script insecurely creates several temporary files with predictable filenames.
A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When rkhunter or the check_update.sh script runs, this would result in the file being overwritten with the rights of the user running the utility, which could be the root user.
Secunia reports:
A vulnerability has been reported in LSH, which potentially can be exploited by malicious people to cause a DoS (Denial of Service).
Matthias Andree reports:
fetchmail will generate warning messages in certain circumstances (for instance, when leaving oversized messages on the server or login to the upstream fails) and send them to the local postmaster or the user running it.
If this warning message is then refused by the SMTP listener that fetchmail is forwarding the message to, fetchmail crashes and does not collect further messages until it is restarted.
Red Hat reports:
A path traversal flaw was discovered in the way GNU tar extracted archives. A malicious user could create a tar archive that could write to arbitrary files to which the user running GNU tar had write access.
Red Hat credits Dmitry V. Levin for reporting the issue.
A Secunia Advisory reports:
A format string error in the "inc_put_error()" function in src/inc.c when displaying a POP3 server's error response can be exploited via specially crafted POP3 server replies containing format specifiers.
Successful exploitation may allow execution of arbitrary code, but requires that the user is tricked into connecting to a malicious POP3 server.
BugTraq reports:
The rsync utility is prone to an off-by-one buffer-overflow vulnerability. This issue is due to a failure of the application to properly bounds-check user-supplied input.
Successfully exploiting this issue may allow arbitrary code-execution in the context of the affected utility.
An advisory from Opera reports:
A specially crafted JavaScript can make Opera execute arbitrary code.
A Secunia Advisory reports:
fsplib can be exploited to compromise an application using the library.
A boundary error exists in the processing of file names in fsp_readdir_native, which can be exploited to cause a stack-based buffer overflow if the defined MAXNAMLEN is bigger than 256.
A boundary error exists in the processing of directory entries in fsp_readdir, which can be exploited to cause a stack-based buffer overflow on systems with an insufficient size allocated for the d_name field of directory entries.
A Secunia Advisory reports:
joomla can be exploited to conduct session fixation attacks, cross-site scripting attacks or HTTP response splitting attacks.
Certain unspecified input passed in com_search, com_content and mod_login is not properly sanitised before being returned to a user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Input passed to the url parameter is not properly sanitised before being returned to the user. This can be exploited to insert arbitrary HTTP headers, which will be included in a response sent to the user, allowing for execution of arbitrary HTML and script code in a user's browser session in context of an affected site.
An error exists in the handling of sessions and can be exploited to hijack another user's session by tricking the user into logging in after following a specially crafted link.
An un-checked return value in the BGP dissector code can result in an integer overflow. This value is used in subsequent buffer management operations, resulting in a stack based buffer overflow under certain circumstances.
By crafting malicious BGP packets, an attacker could exploit this vulnerability to execute code or crash the tcpdump process on the target system. This code would be executed in the context of the user running tcpdump(1). It should be noted that tcpdump(1) requires privileges in order to open live network interfaces.
No workaround is available.
When named(8) is operating as a recursive DNS server or sending NOTIFY requests to slave DNS servers, named(8) uses a predictable query id.
An attacker who can see the query id for some request(s) sent by named(8) is likely to be able to perform DNS cache poisoning by predicting the query id for other request(s).
No workaround is available.
The KDE Team reports:
kpdf, the KDE pdf viewer, shares code with xpdf. xpdf contains a vulnerability that can cause a stack based buffer overflow via a PDF file that exploits an integer overflow in StreamPredictor::StreamPredictor(). Remotely supplied pdf files can be used to disrupt the kpdf viewer on the client machine and possibly execute arbitrary code.
Securityfocus reports:
Mutt is prone to a local buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before using it in a memory copy operation. An attacker can exploit this issue to execute arbitrary code with the with the privileges of the victim. Failed exploit attempts will result in a denial of service.
A Secunia Advisory reports:
An error exists in the handling of DNS queries where IDs are incremented with a fixed value and are additionally used for child processes in a forking server. This can be exploited to poison the DNS cache of an application using the module if a valid ID is guessed.
An error in the PP implementation within the "dn_expand()" function can be exploited to cause a stack overflow due to an endless loop via a specially crafted DNS packet.
Doz reports:
A Input passed in the URL to index.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The Drupal Project reports:
Several parts in Drupal core are not protected against cross site request forgeries due to inproper use of the Forms API, or by taking action solely on GET requests. Malicious users are able to delete comments and content revisions and disable menu items by enticing a privileged users to visit certain URLs while the victim is logged-in to the targeted site.
The Drupal Project reports:
Some server variables are not escaped consistently. When a malicious user is able to entice a victim to visit a specially crafted link or webpage, arbitrary HTML and script code can be injected and executed in the context of the victim's session on the targeted website.
Custom content type names are not escaped consistently. A malicious user with the 'administer content types' permission would be able to inject and execute arbitrary HTML and script code on the website. Revoking the 'administer content types' permission provides an immediate workaround.
A Secunia Advisory reports:
A format string error in the "helptags_one()" function in src/ex_cmds.c when running the "helptags" command can be exploited to execute arbitrary code via specially crafted help files.
isecpartners reports:
libvorbis contains several vulnerabilities allowing heap overwrite, read violations and a function pointer overwrite. These bugs cause a at least a denial of service, and potentially code execution.
The Apache Project reports:
The JSP and Servlet included in the sample application within the Tomcat documentation webapp did not escape user provided data before including it in the output. This enabled a XSS attack. These pages have been simplified not to use any user provided data in the output.
Apache Project reports:
The Apache Tomcat team is proud to announce the immediate availability of Tomcat 4.1.36 stable. This build contains numerous library updates, A small number of bug fixes and two important security fixes.
DokuWiki reports:
The spellchecker tests the UTF-8 capabilities of the used browser by sending an UTF-8 string to the backend, which will send it back unfiltered. By comparing string length the spellchecker can work around broken implementations. An attacker could construct a form to let users send JavaScript to the spellchecker backend, resulting in malicious JavaScript being executed in their browser.
Affected are all versions up to and including 2007-06-26 even when the spell checker is disabled.
Secunia Advisory reports:
Some vulnerabilities have been reported in lighttpd, which can be exploited by malicious people to bypass certain security restrictions or cause a DoS (Denial of Service).
Opera Software ASA reports of multiple security fixes in Opera, including an arbitrary code execute vulnerability:
Opera for Linux, FreeBSD, and Solaris has a flaw in the createPattern function that leaves old data that was in the memory before Opera allocated it in the new pattern. The pattern can be read and analyzed by JavaScript, so an attacker can get random samples of the user's memory, which may contain data.
Removing a specially crafted torrent from the download manager can crash Opera. The crash is caused by an erroneous memory access.
An attacker needs to entice the user to accept the malicious BitTorrent download, and later remove it from Opera's download manager. To inject code, additional means will have to be employed.
Users clicking a BitTorrent link and rejecting the download are not affected.
data: URLs embed data inside them, instead of linking to an external resource. Opera can mistakenly display the end of a data URL instead of the beginning. This allows an attacker to spoof the URL of a trusted site.
Opera's HTTP authentication dialog is displayed when the user enters a Web page that requires a login name and a password. To inform the user which server it was that asked for login credentials, the dialog displays the server name.
The user has to see the entire server name. A truncated name can be misleading. Opera's authentication dialog cuts off the long server names at the right hand side, adding an ellipsis (...) to indicate that it has been cut off.
The dialog has a predictable size, allowing an attacker to create a server name which will look almost like a trusted site, because the real domain name has been cut off. The three dots at the end will not be obvious to all users.
This flaw can be exploited by phishers who can set up custom sub-domains, for example by hosting their own public DNS.
The Mozilla Foundation reports of multiple security issues in Firefox, Seamonkey, and Thunderbird. Several of these issues can probably be used to run arbitrary code with the privilege of the user running the program.
- MFSA 2007-25 XPCNativeWrapper pollution
- MFSA 2007-24 Unauthorized access to wyciwyg:// documents
- MFSA 2007-21 Privilege escalation using an event handler attached to an element not in the document
- MFSA 2007-20 Frame spoofing while window is loading
- MFSA 2007-19 XSS using addEventListener and setTimeout
- MFSA 2007-18 Crashes with evidence of memory corruption
Adobe reports:
Critical vulnerabilities have been identified in Adobe Flash Player that could allow an attacker who successfully exploits these potential vulnerabilities to take control of the affected system. A malicious SWF must be loaded in Flash Player by the user for an attacker to exploit these potential vulnerabilities.
wireshark Team reports:
It may be possible to make Wireshark or Ethereal crash or use up available memory by injecting a purposefully malformed packet onto the wire or by convincing someone to read a malformed packet trace file.
Debian reports:
Ulf Härnhammar from the Debian Security Audit Project discovered a problem in typespeed, a touch-typist trainer disguised as game. This could lead to a local attacker executing arbitrary code.
isecpartners reports:
VLC is vulnerable to a format string attack in the parsing of Vorbis comments in Ogg Vorbis and Ogg Theora files, CDDA data or SAP/SDP service discovery messages. Additionally, there are two errors in the handling of wav files, one a denial of service due to an uninitialized variable, and one integer overflow in sampling frequency calculations.
isecpartners reports:
flac123, also known as flac-tools, is vulnerable to a buffer overflow in vorbis comment parsing. This allows for the execution of arbitrary code.
gd had been reported vulnerable to several vulnerabilities:
Debian project reports:
It was discovered that the IMAP code in the Evolution Data Server performs insufficient sanitising of a value later used an array index, which can lead to the execution of arbitrary code.
Debian Project reports:
Erik Sjolund discovered a buffer overflow in pcdsvgaview, an SVGA PhotoCD viewer. xpcd-svga is part of xpcd and uses svgalib to display graphics on the Linux console for which root permissions are required. A malicious user could overflow a fixed-size buffer and may cause the program to execute arbitrary code with elevated privileges.
Clamav had been found vulnerable to multiple vulnerabilities:
SpamAssassin website reports:
A local user symlink-attack DoS vulnerability in SpamAssassin has been found, affecting versions 3.1.x, 3.2.0, and SVN trunk.
Secunia reports:
CUPS is not using multiple workers to handle connections. This can be exploited to stop CUPS from accepting new connections by starting but never completing an SSL negotiation.
Secunia reports:
The vulnerability is caused due to predictable DNS "Transaction ID" field in DNS queries and can be exploited to poison the DNS cache of an application using the library if a valid ID is guessed.
Secunia reports:
Slappter has discovered a vulnerability in WordPress, which can be exploited by malicious users to conduct SQL injection attacks.
Input passed to the "wp.suggestCategories" method in xmlrpc.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation allows e.g. retrieving usernames and password hashes, but requires valid user credentials and knowledge of the database table prefix.
Blogsecurity reports:
An attacker can read comments on posts that have not been moderated. This can be a real security risk if blog admins are using unmoderated comments (comments that have not been made public) to hide sensitive notes regarding posts, future work, passwords etc. So please be careful if you are one of these blog admins.
Secunia reports:
Input passed to unspecified parameters in pam_login.cgi is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Mplayer Team reports:
A stack overflow was found in the code used to handle cddb queries. When copying the album title and category, no checking was performed on the size of the strings before storing them in a fixed-size array. A malicious entry in the database could trigger a stack overflow in the program, leading to arbitrary code execution with the uid of the user running MPlayer.
Kazu Nambo reports:
URL decoding the the Apache webserver prior to decoding in the Tomcat server could pypass access control rules and give access to pages on a different AJP by sending a crafted URL.
Olivier Dobberkau, Andreas Otto, and Thorsten Kahler report:
An unspecified error in the internal form engine can be used for sending arbitrary mail headers, using it for purposes which it is not meant for, e.g. sending spam messages.
SecurityFocus reports about phppgadmin:
Exploiting this vulnerability may allow an attacker to perform cross-site scripting attacks on unsuspecting users in the context of the affected website. As a result, the attacker may be able to steal cookie-based authentication credentials and to launch other attacks.
James Youngman reports:
When GNU locate reads filenames from an old-format locate database, they are read into a fixed-length buffer allocated on the heap. Filenames longer than the 1026-byte buffer can cause a buffer overrun. The overrunning data can be chosen by any person able to control the names of filenames created on the local system. This will normally include all local users, but in many cases also remote users (for example in the case of FTP servers allowing uploads).
Integer signedness error in truetype/ttgload.c in Freetype 2.3.4 and earlier might allow remote attackers to execute arbitrary code via a crafted TTF image with a negative n_points value, which leads to an integer overflow and heap-based buffer overflow.
When writing data into a buffer in the file_printf function, the length of the unused portion of the buffer is not correctly tracked, resulting in a buffer overflow when processing certain files.
An attacker who can cause file(1) to be run on a maliciously constructed input can cause file(1) to crash. It may be possible for such an attacker to execute arbitrary code with the privileges of the user running file(1).
The above also applies to any other applications using the libmagic(3) library.
No workaround is available, but systems where file(1) and other libmagic(3)-using applications are never run on untrusted input are not vulnerable.
The SquirrelMail developers report:
Multiple cross-site scripting (XSS) vulnerabilities in the HTML filter in SquirrelMail 1.4.0 through 1.4.9a allow remote attackers to inject arbitrary web script or HTML via the (1) data: URI in an HTML e-mail attachment or (2) various non-ASCII character sets that are not properly filtered when viewed with Microsoft Internet Explorer.
A Libpng Security Advisory reports:
A grayscale PNG image with a malformed (bad CRC) tRNS chunk will crash some libpng applications.
This vulnerability could be used to crash a browser when a user tries to view such a malformed PNG file. It is not known whether the vulnerability could be exploited otherwise.
The Samba Team reports:
A bug in the local SID/Name translation routines may potentially result in a user being able to issue SMB/CIFS protocol operations as root.
When translating SIDs to/from names using Samba local list of user and group accounts, a logic error in the smbd daemon's internal security stack may result in a transition to the root user id rather than the non-root user. The user is then able to temporarily issue SMB/CIFS protocol operations as the root user. This window of opportunity may allow the attacker to establish additional means of gaining root access to the server.
Various bugs in Samba's NDR parsing can allow a user to send specially crafted MS-RPC requests that will overwrite the heap space with user defined data.
Unescaped user input parameters are passed as arguments to /bin/sh allowing for remote command execution.
This bug was originally reported against the anonymous calls to the SamrChangePassword() MS-RPC function in combination with the "username map script" smb.conf option (which is not enabled by default).
After further investigation by Samba developers, it was determined that the problem was much broader and impacts remote printer and file share management as well. The root cause is passing unfiltered user input provided via MS-RPC calls to /bin/sh when invoking externals scripts defined in smb.conf. However, unlike the "username map script" vulnerability, the remote file and printer management scripts require an authenticated user session.
The PHP development team reports:

The Debian Security Team reports:
Several vulnerabilities have been discovered in the QEMU processor emulator, which may lead to the execution of arbitrary code or denial of service. The Common Vulnerabilities and Exposures project identifies the following problems:
CVE-2007-1320
Tavis Ormandy discovered that a memory management routine of the Cirrus video driver performs insufficient bounds checking, which might allow the execution of arbitrary code through a heap overflow.CVE-2007-1321
Tavis Ormandy discovered that the NE2000 network driver and the socket code perform insufficient input validation, which might allow the execution of arbitrary code through a heap overflow.CVE-2007-1322
Tavis Ormandy discovered that the "icebp" instruction can be abused to terminate the emulation, resulting in denial of service.CVE-2007-1323
Tavis Ormandy discovered that the NE2000 network driver and the socket code perform insufficient input validation, which might allow the execution of arbitrary code through a heap overflow.CVE-2007-1366
Tavis Ormandy discovered that the "aam" instruction can be abused to crash qemu through a division by zero, resulting in denial of service.
Imager 0.56 and all earlier versions with BMP support have a security issue when reading compressed 8-bit per pixel BMP files where either a compressed run of data or a literal run of data overflows the scan-line.
Such an overflow causes a buffer overflow in a malloc() allocated memory buffer, possibly corrupting the memory arena headers.
The effect depends on your system memory allocator, with glibc this typically results in an abort, but with other memory allocators it may be possible to cause local code execution.
There is no mechanism for preventing IPv6 routing headers from being used to route packets over the same link(s) many times.
An attacker can "amplify" a denial of service attack against a link between two vulnerable hosts; that is, by sending a small volume of traffic the attacker can consume a much larger amount of bandwidth between the two vulnerable hosts.
An attacker can use vulnerable hosts to "concentrate" a denial of service attack against a victim host or network; that is, a set of packets sent over a period of 30 seconds or more could be constructed such that they all arrive at the victim within a period of 1 second or less over a period of 30 seconds or more could be constructed such that they all arrive at the victim within a period of 1 second or less.
Other attacks may also be possible.
No workaround is available.
Mandriva reports:
PerlRun.pm in Apache mod_perl 1.29 and earlier, and RegistryCooker.pm in mod_perl 2.x, does not properly escape PATH_INFO before use in a regular expression, which allows remote attackers to cause a denial of service (resource consumption) via a crafted URI.
CVE reports:
The APOP protocol allows remote attackers to guess the first 3 characters of a password via man-in-the-middle (MITM) attacks that use crafted message IDs and MD5 collisions.
Lighttpd SA:
Lighttpd caches the rendered string for mtime. The cache key has as a default value 0. At that point the pointer to the string are still NULL. If a file with an mtime of 0 is requested it tries to access the pointer and crashes.
The bug requires that a malicious user can either upload files or manipulate the mtime of the files.
The bug was reported by cubiq and fixed by Marcus Rueckert.
Lighttpd SA:
If the connection aborts during parsing "\r\n\r\n" the server might get into a infinite loop and use 100% of the CPU time. lighttpd still responses to other requests. This can be repeated until either the server limit for concurrent connections or file descriptors is reached.
The bug was reported and fixed by Robert Jakabosky.
The freeradius development team reports:
A malicious 802.1x supplicant could send malformed Diameter format attributes inside of an EAP-TTLS tunnel. The server would reject the authentication request, but would leak one VALUE_PAIR data structure, of approximately 300 bytes. If an attacker performed the attack many times (e.g. thousands or more over a period of minutes to hours), the server could leak megabytes of memory, potentially leading to an "out of memory" condition, and early process exit.
Matthias Andree reports:
The POP3 standard, currently RFC-1939, has specified an optional, MD5-based authentication scheme called "APOP" which no longer should be considered secure.
Additionally, fetchmail's POP3 client implementation has been validating the APOP challenge too lightly and accepted random garbage as a POP3 server's APOP challenge. This made it easier than necessary for man-in-the-middle attackers to retrieve by several probing and guessing the first three characters of the APOP secret, bringing brute forcing the remaining characters well within reach.
CVE reports:
Buffer overflow in eject.c in Jason W. Bacon mcweject 0.9 on FreeBSD, and possibly other versions, allows local users to execute arbitrary code via a long command line argument, possibly involving the device name.
Secunia reports:
A vulnerability has been discovered in WebCalendar, which can be exploited by malicious people to compromise a vulnerable system.
Input passed to unspecified parameters is not properly verified before being used with the "noSet" parameter set. This can be exploited to overwrite certain variables, and allows e.g. the inclusion of arbitrary PHP files from internal or external resources.
The Zope Team reports:
A vulnerability has been discovered in Zope, where by certain types of misuse of HTTP GET, an attacker could gain elevated privileges. All Zope versions up to and including 2.10.2 are affected.
Squid advisory 2007:1 notes:
Due to an internal error Squid-2.6 is vulnerable to a denial of service attack when processing the TRACE request method.
Workarounds:
To work around the problem deny access to using the TRACE method by inserting the following two lines before your first http_access rule.
acl TRACE method TRACE
http_access deny TRACE
Chris Travers reports:
George Theall of Tenable Security notified the LedgerSMB core team today of an authentication bypass vulnerability allowing full access to the administrator interface of LedgerSMB 1.1 and SQL-Ledger 2.x. The problem is caused by the password checking routine failing to enforce a password check under certain circumstances. The user can then create accounts or effect denial of service attacks.
This is not related to any previous CVE.
We have coordinated with the SQL-Ledger vendor and today both of us released security patches correcting the problem. SQL-Ledger users who can upgrade to 2.6.26 should do so, and LedgerSMB 1.1 or 1.0 users should upgrade to 1.1.9. Users who cannot upgrade should configure their web servers to use http authentication for the admin.pl script in the main root directory.
The Samba Team reports:
Internally Samba's file server daemon, smbd, implements support for deferred file open calls in an attempt to serve client requests that would otherwise fail due to a share mode violation. When renaming a file under certain circumstances it is possible that the request is never removed from the deferred open queue. smbd will then become stuck is a loop trying to service the open request.
This bug may allow an authenticated user to exhaust resources such as memory and CPU on the server by opening multiple CIFS sessions, each of which will normally spawn a new smbd process, and sending each connection into an infinite loop.
The Samba Team reports:
NOTE: This security advisory only impacts Samba servers that share AFS file systems to CIFS clients and which have been explicitly instructed in smb.conf to load the afsacl.so VFS module.
The source defect results in the name of a file stored on disk being used as the format string in a call to snprintf(). This bug becomes exploitable only when a user is able to write to a share which utilizes Samba's afsacl.so library for setting Windows NT access control lists on files residing on an AFS file system.
Two problems have been found in KTorrent:
"Moritz Jodeit reports:
There's an exploitable buffer overflow in the current version of MPlayer (v1.0rc1) which can be exploited with a maliciously crafted video file. It is hidden in the DMO_VideoDecoder() function of `loader/dmo/DMO_VideoDecoder.c' file.
Secunia reports:
The vulnerability is caused due to an error within the "download wiki page as text" function, which can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Successful exploitation may require that the victim uses IE.
TippingPoint and The Zero Day Initiative reports:
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apache Tomcat JK Web Server Connector. Authentication is not required to exploit this vulnerability.
The specific flaw exists in the URI handler for the mod_jk.so library, map_uri_to_worker(), defined in native/common/jk_uri_worker_map.c. When parsing a long URL request, the URI worker map routine performs an unsafe memory copy. This results in a stack overflow condition which can be leveraged to execute arbitrary code.
A type * (ANY) query response containing multiple RRsets can trigger an assertion failure.
Certain recursive queries can cause the nameserver to crash by using memory which has already been freed.
A remote attacker sending a type * (ANY) query to an authoritative DNS server for a DNSSEC signed zone can cause the named(8) daemon to exit, resulting in a Denial of Service.
A remote attacker sending recursive queries can cause the nameserver to crash, resulting in a Denial of Service.
There is no workaround available, but systems which are not authoritative servers for DNSSEC signed zones are not affected by the first issue; and systems which do not permit untrusted users to perform recursive DNS resolution are not affected by the second issue. Note that the default configuration for named(8) in FreeBSD allows local access only (which on many systems is equivalent to refusing access to untrusted users).
In multiple situations the host's jail rc.d(8) script does not check if a path inside the jail file system structure is a symbolic link before using the path. In particular this is the case when writing the output from the jail start-up to /var/log/console.log and when mounting and unmounting file systems inside the jail directory structure.
Due to the lack of handling of potential symbolic links the host's jail rc.d(8) script is vulnerable to "symlink attacks". By replacing /var/log/console.log inside the jail with a symbolic link it is possible for the superuser (root) inside the jail to overwrite files on the host system outside the jail with arbitrary content. This in turn can be used to execute arbitrary commands with non-jailed superuser privileges.
Similarly, by changing directory mount points inside the jail file system structure into symbolic links, it may be possible for a jailed attacker to mount file systems which were meant to be mounted inside the jail at arbitrary points in the host file system structure, or to unmount arbitrary file systems on the host system.
NOTE WELL: The above vulnerabilities occur only when a jail is being started or stopped using the host's jail rc.d(8) script; once started (and until stopped), running jails cannot exploit this.
If the sysctl(8) variable security.jail.chflags_allowed is set to 0 (the default), setting the "sunlnk" system flag on /var, /var/log, /var/log/console.log, and all file system mount points and their parent directories inside the jail(s) will ensure that the console log file and mount points are not replaced by symbolic links. If this is done while jails are running, the administrator must check that an attacker has not replaced any directories with symlinks after setting the "sunlnk" flag.
Symlinks created using the "GNUTYPE_NAMES" tar extension can be absolute due to lack of proper sanity checks.
If an attacker can get a user to extract a specially crafted tar archive the attacker can overwrite arbitrary files with the permissions of the user running gtar. If file system permissions allow it, this may allow the attacker to overwrite important system file (if gtar is being run as root), or important user configuration files such as .tcshrc or .bashrc, which would allow the attacker to run arbitrary commands.
Use "bsdtar", which is the default tar implementation in FreeBSD 5.3 and higher. For FreeBSD 4.x, bsdtar is available in the FreeBSD Ports Collection as ports/archivers/libarchive.
In the FW_GCROM ioctl, a signed integer comparison is used instead of an unsigned integer comparison when computing the length of a buffer to be copied from the kernel into the calling application.
A user in the "operator" group can read the contents of kernel memory. Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way; for example, a terminal buffer might include a user-entered password.
No workaround is available, but systems without IEEE 1394 ("FireWire") interfaces are not vulnerable. (Note that systems with IEEE 1394 interfaces are affected regardless of whether any devices are attached.)
Note also that FreeBSD does not have any non-root users in the "operator" group by default; systems on which no users have been added to this group are therefore also not vulnerable.
If the end of an archive is reached while attempting to "skip" past a region of an archive, libarchive will enter an infinite loop wherein it repeatedly attempts (and fails) to read further data.
An attacker able to cause a system to extract (via "tar -x" or another application which uses libarchive) or list the contents (via "tar -t" or another libarchive-using application) of an archive provided by the attacker can cause libarchive to enter an infinite loop and use all available CPU time.
No workaround is available.
Several problems have been found in OpenSSL:
In addition, many applications using OpenSSL do not perform any validation of the lengths of public keys being used.
Servers which parse ASN1 data from untrusted sources may be vulnerable to a denial of service attack.
An attacker accessing a server which uses SSL version 2 may be able to execute arbitrary code with the privileges of that server.
A malicious SSL server can cause clients connecting using SSL version 2 to crash.
Applications which perform public key operations using untrusted keys may be vulnerable to a denial of service attack.
No workaround is available, but not all of the vulnerabilities mentioned affect all applications.
The Mozilla Foundation reports of multiple security issues in Firefox, Seamonkey, and Thunderbird. Several of these issues can probably be used to run arbitrary code with the privilege of the user running the program.

A IBM Internet Security Systems Protection Advisory reports:
Snort is vulnerable to a stack-based buffer overflow as a result of DCE/RPC reassembly. This vulnerability is in a dynamic-preprocessor enabled in the default configuration, and the configuration for this preprocessor allows for auto-recognition of SMB traffic to perform reassembly on. No checks are performed to see if the traffic is part of a valid TCP session, and multiple Write AndX requests can be chained in the same TCP segment. As a result, an attacker can exploit this overflow with a single TCP PDU sent across a network monitored by Snort or Sourcefire.
Snort users who cannot upgrade immediately are advised to disable the DCE/RPC preprocessor by removing the DCE/RPC preprocessor directives from snort.conf and restarting Snort. However, be advised that disabling the DCE/RPC preprocessor reduces detection capabilities for attacks in DCE/RPC traffic. After upgrading, customers should re-enable the DCE/RPC preprocessor.
iDefense reports:
Remote exploitation of a stack based buffer overflow vulnerability in RARLabs Unrar may allow an attacker to execute arbitrary code with the privileges of the user opening the archive.
Unrar is prone to a stack based buffer overflow when processing specially crafted password protected archives.
If users are using the vulnerable command line based unrar, they still need to interact with the program in order to trigger the vulnerability. They must respond to the prompt asking for the password, after which the vulnerability will be triggered. They do not need to enter a correct password, but they must at least push the enter key.
Multiple vulnerabilities have been found in PHP, including: buffer overflows, stack overflows, format string, and information disclosure vulnerabilities.
The session extension contained safe_mode
and
open_basedir
bypasses, but the FreeBSD Security
Officer does not consider these real security
vulnerabilities, since safe_mode
and
open_basedir
are insecure by design and should
not be relied upon.
Secunia reports:
Some vulnerabilities have been reported in Joomla!, where some have unknown impacts and one can be exploited by malicious people to conduct cross-site scripting attacks.
- Input passed to an unspecified parameter is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
- The vulnerabilities are caused due to unspecified errors in Joomla!. The vendor describes them as "several low level security issues". No further information is currently available.
Secunia reports:
A vulnerability in sircd can be exploited by a malicious person to compromise a vulnerable system. The vulnerability is caused by a boundary error in the code handling reverse DNS lookups, when a user connects to the service. If the FQDN (Fully Qualified Domain Name) returned is excessively long, the allocated buffer is overflowed making it possible to execute arbitrary code on the system with the privileges of the sircd daemon.
Secunia reports:
A vulnerability has been reported in sircd, which can be exploited by malicious users to gain operator privileges. The problem is that any user reportedly can set their usermode to operator. The vulnerability has been reported in versions 0.5.2 and 0.5.3. Other versions may also be affected.
Secunia reports:
rgod has discovered four vulnerabilities in Cacti, which can be exploited by malicious people to bypass certain security restrictions, manipulate data and compromise vulnerable systems.
A potential buffer overflow was found in the code used to handle RealMedia RTSP streams. When checking for matching asm rules, the code stores the results in a fixed-size array, but no boundary checks are performed. This may lead to a buffer overflow if the user is tricked into connecting to a malicious server. Since the attacker cannot write arbitrary data into the buffer, creating an exploit is very hard; but a DoS attack is easily made. A fix for this problem was committed to SVN on Sun Dec 31 13:27:53 2006 UTC as r21799. The fix involves three files: stream/realrtsp/asmrp.c, stream/realrtsp/asmrp.h and stream/realrtsp/real.c.
Matthias Andree reports:
When delivering messages to a message delivery agent by means of the "mda" option, fetchmail can crash (by passing a NULL pointer to ferror() and fflush()) when refusing a message. SMTP and LMTP delivery modes aren't affected.
Matthias Andree reports:
Fetchmail has had several longstanding password disclosure vulnerabilities.
- sslcertck/sslfingerprint options should have implied "sslproto tls1" in order to enforce TLS negotiation, but did not.
- Even with "sslproto tls1" in the config, fetches would go ahead in plain text if STLS/STARTTLS wasn't available (not advertised, or advertised but rejected).
- POP3 fetches could completely ignore all TLS options whether available or not because it didn't reliably issue CAPA before checking for STLS support - but CAPA is a requisite for STLS. Whether or not CAPAbilities were probed, depended on the "auth" option. (Fetchmail only tried CAPA if the auth option was not set at all, was set to gssapi, kerberos, kerberos_v4, otp, or cram-md5.)
- POP3 could fall back to using plain text passwords, even if strong authentication had been configured.
- POP2 would not complain if strong authentication or TLS had been requested.
iDefense reports:
The vulnerability specifically exists due to Opera improperly processing a JPEG DHT marker. The DHT marker is used to define a Huffman Table which is used for decoding the image data. An invalid number of index bytes in the DHT marker will trigger a heap overflow with partially user controlled data.
Exploitation of this vulnerability would allow an attacker to execute arbitrary code on the affected host. The attacker would first need to construct a website containing the malicious image and trick the vulnerable user into visiting the site. This would trigger the vulnerability and allow the code to execute with the privileges of the local user.
A flaw exists within Opera's Javascript SVG implementation. When processing a createSVGTransformFromMatrix request Opera does not properly validate the type of object passed to the function. Passing an incorrect object to this function can result in it using a pointer that is user controlled when it attempts to make the virtual function call.
Exploitation of this vulnerability would allow an attacker to execute arbitrary code on the affected host. The attacker would first need to construct a website containing the malicious JavaScript and trick the vulnerable user into visiting the site. This would trigger the vulnerability and allow the code to execute with the privileges of the local user.
The Drupal security team reports:
A few arguments passed via URLs are not properly sanitized before display. When an attacker is able to entice an administrator to follow a specially crafted link, arbitrary HTML and script code can be injected and executed in the victim's session. Such an attack may lead to administrator access if certain conditions are met.
The way page caching was implemented allows a denial of service attack. An attacker has to have the ability to post content on the site. He or she would then be able to poison the page cache, so that it returns cached 404 page not found errors for existing pages.
If the page cache is not enabled, your site is not vulnerable. The vulnerability only affects sites running on top of MySQL.
An anonymous person reports:
w3m-0.5.1 crashes when using the -dump or -backend options to open a HTTPS URL with a SSL certificate where the CN contains "%n%n%n%n%n%n".
Plone.org reports:
PlonePAS-using Plone releases (Plone 2.5 and Plone 2.5.1) has a potential vulnerability that allows a user to masquerade as a group. Please update your sites.
The proftpd development team reports that several remote buffer overflows had been found in the proftpd server.
Multiple programming errors have been found in gzip which can be triggered when gzip is decompressing files. These errors include insufficient bounds checks in buffer use, a NULL pointer dereference, and a potential infinite loop.
The insufficient bounds checks in buffer use can cause gzip to crash, and may permit the execution of arbitrary code. The NULL pointer deference can cause gzip to crash. The infinite loop can cause a Denial-of-Service situation where gzip uses all available CPU time.
No workaround is available.
For a recursive DNS server, a remote attacker sending enough recursive queries for the replies to arrive after all the interested clients have left the recursion queue will trigger an INSIST failure in the named(8) daemon. Also for a recursive DNS server, an assertion failure can occur when processing a query whose reply will contain more than one SIG(covered) RRset.
For an authoritative DNS server serving a RFC 2535 DNSSEC zone which is queried for the SIG records where there are multiple SIG(covered) RRsets (e.g. a zone apex), named(8) will trigger an assertion failure when it tries to construct the response.
An attacker who can perform recursive lookups on a DNS server and is able to send a sufficiently large number of recursive queries, or is able to get the DNS server to return more than one SIG(covered) RRsets can stop the functionality of the DNS service.
An attacker querying an authoritative DNS server serving a RFC 2535 DNSSEC zone may be able to crash the DNS server.
A possible workaround is to only allow trusted clients to perform recursive queries.
When verifying a PKCS#1 v1.5 signature, OpenSSL ignores any bytes which follow the cryptographic hash being signed. In a valid signature there will be no such bytes.
OpenSSL will incorrectly report some invalid signatures as valid. When an RSA public exponent of 3 is used, or more generally when a small public exponent is used with a relatively large modulus (e.g., a public exponent of 17 with a 4096-bit modulus), an attacker can construct a signature which OpenSSL will accept as a valid PKCS#1 v1.5 signature.
No workaround is available.
The Debian security Team reports:
Several remote vulnerabilities have been discovered in SQL Ledger, a web based double-entry accounting program, which may lead to the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems:
Chris Travers discovered that the session management can be tricked into hijacking existing sessions.
Chris Travers discovered that directory traversal vulnerabilities can be exploited to execute arbitrary Perl code.
It was discovered that missing input sanitising allows execution of arbitrary Perl code.
Secunia reports:
D-Bus have a weakness, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
An error within the "match_rule_equal()" function can be exploited to disable the ability of other processes to receive messages by removing their matches from D-Bus.
Secunia reports:
A vulnerability has been discovered in Evince, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error within the "get_next_text()" function in ps/ps.c. This can be exploited to cause a buffer overflow by e.g. tricking a user into opening a specially crafted PostScript file.
An undisclosed eRuby injection vulnerability had been discovered in tDiary.
Secunia reports:
Some vulnerabilities have been reported in wvWare, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise an application using the library.
The vulnerabilities are caused due to integer overflows within the "wvGetLFO_records()" and "wvGetLFO_PLF()" functions. These can be exploited to cause heap-based buffer overflows by e.g. tricking a user to open a specially crafted Microsoft Word document with an application using the library.
Secunia reports:
A vulnerability has been reported in wvWare wv2 Library, which potentially can be exploited by malicious people to compromise an application using the library.
The vulnerability is caused due to an integer overflow error in "word_helper.h" when handling a Word document. This can be exploited to cause a buffer overflow and may allow arbitrary code execution via a specially crafted Word document.
The tnftpd port suffer from a remote stack overrun, which can lead to a root compromise.
Secunia reports:
Clam AntiVirus have a vulnerability, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to a stack overflow when scanning messages with deeply nested multipart content. This can be exploited to crash the service by sending specially crafted emails to a vulnerable system.
The libxine development team reports that several vulnerabilities had been found in the libxine library. The first vulnerability is caused by improper checking of the src/input/libreal/real.c "real_parse_sdp()" function. A remote attacker could exploit this by tricking an user to connect to a preparated server potentially causing a buffer overflow. Another buffer overflow had been found in the libmms library, potentially allowing a remote attacker to cause a denial of service vulnerability, and possible remote code execution through the following functions: send_command, string_utf16, get_data and get_media_packets. Other functions might be affected as well.
Werner Koch reports:
GnuPG uses data structures called filters to process OpenPGP messages. These filters are used in a similar way as a pipelines in the shell. For communication between these filters context structures are used. These are usually allocated on the stack and passed to the filter functions. At most places the OpenPGP data stream fed into these filters is closed before the context structure gets deallocated. While decrypting encrypted packets, this may not happen in all cases and the filter may use a void contest structure filled with garbage. An attacker may control this garbage. The filter context includes another context used by the low-level decryption to access the decryption algorithm. This is done using a function pointer. By carefully crafting an OpenPGP message, an attacker may control this function pointer and call an arbitrary function of the process. Obviously an exploit needs to prepared for a specific version, compiler, libc, etc to be successful - but it is definitely doable.
Fixing this is obvious: We need to allocate the context on the heap and use a reference count to keep it valid as long as either the controlling code or the filter code needs it.
We have checked all other usages of such a stack based filter contexts but fortunately found no other vulnerable places. This allows to release a relatively small patch. However, for reasons of code cleanness and easier audits we will soon start to change all these stack based filter contexts to heap based ones.
The official ruby site reports:
Another vulnerability has been discovered in the CGI library (cgi.rb) that ships with Ruby which could be used by a malicious user to create a denial of service attack (DoS).
A specific HTTP request for any web application using cgi.rb causes CPU consumption on the machine on which the web application is running. Many such requests result in a denial of service.
SecurityFocus reports about libmusicbrainz:
The libmusicbrainz library is prone to multiple buffer-overflow vulnerabilities because the application fails to check the size of the data before copying it into a finite-sized internal memory buffer.
An attacker can exploit these issues to execute arbitrary code within the context of the application or to cause a denial-of-service condition.
tDiary was vulnerable to an unspecified Cross-Site Scripting vulnerability
SecurityFocus reports about ImageMagick:
ImageMagick is prone to a remote heap-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.
Exploiting this issue allows attackers to execute arbitrary machine code in the context of applications that use the ImageMagick library.
Teemu Salmela reports:
There is a tar record type, called GNUTYPE_NAMES (an obsolete GNU extension), that allows the creation of symbolic links pointing to arbitrary locations in the filesystem, which makes it possible to create/overwrite arbitrary files.
iDefense Labs reports:
Remote exploitation of a design error in Horde's Kronolith could allow an authenticated web mail user to execute arbitrary PHP code under the security context of the running web server.
The vulnerability specifically exists due to a design error in the way it includes certain files. Specifically, the 'lib/FBView.php' file contains a function 'Kronolith_FreeBusy_View::factory' which will include local files that are supplied via the 'view' HTTP GET request parameter.
Werner Koch reports:
When running GnuPG interactively, special crafted messages may be used to crash gpg or gpg2. Running gpg in batch mode, as done by all software using gpg as a backend (e.g. mailers), is not affected by this bug.
Exploiting this overflow seems to be possible.
gpg-agent, gpgsm, gpgv or other tools from the GnuPG suite are not affected.
FrSIRT reports:
A vulnerability has been identified in ProFTPD, which could be exploited by attackers to cause a denial of service or execute arbitrary commands. This flaw is due to a buffer overflow error in the "main.c" file where the "cmd_buf_size" size of the buffer used to handle FTP commands sent by clients is not properly set to the size configured via the "CommandBufferSize" directive, which could be exploited by attackers to compromise a vulnerable server via a specially crafted FTP command.
Secunia reports:
Doubles has discovered a vulnerability in Unzoo, which potentially can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an input validation error when unpacking archives. This can be exploited via a directory traversal attack to overwrite files outside the directory, where the files are extracted to, if a user is tricked into extracting a malicious archive using Unzoo.
A Bugzilla Security Advisory reports:
- Sometimes the information put into the <h1> and <h2> tags in Bugzilla was not properly escaped, leading to a possible XSS vulnerability.
- Bugzilla administrators were allowed to put raw, unfiltered HTML into many fields in Bugzilla, leading to a possible XSS vulnerability. Now, the HTML allowed in those fields is limited.
- attachment.cgi could leak the names of private attachments
- The "deadline" field was visible in the XML format of a bug, even to users who were not a member of the "timetrackinggroup."
- A malicious user could pass a URL to an admin, and make the admin delete or change something that he had not intended to delete or change.
- It is possible to inject arbitrary HTML into the showdependencygraph.cgi page, allowing for a cross-site scripting attack.
Secunia reports:
Some vulnerabilities have been reported in imlib2, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise an application using the library.
The vulnerabilities are caused due to unspecified errors within the processing of JPG, ARGB, PNG, LBM, PNM, TIFF, and TGA images. This may be exploited to execute arbitrary code by e.g. tricking a user into opening a specially crafted image file with an application using imlib2.
Official ruby site reports:
A vulnerability has been discovered in the CGI library (cgi.rb) that ships with Ruby which could be used by a malicious user to create a denial of service attack (DoS). The problem is triggered by sending the library an HTTP request that uses multipart MIME encoding and as an invalid boundary specifier that begins with "-" instead of "--". Once triggered it will exhaust all available memory resources effectively creating a DoS condition.
A vulnerability in the handling of combined UTF-8 characters in screen may allow an user-assisted attacker to crash screen or potentially allow code execution as the user running screen. To exploit this issue the user running scren must in some way interact with the attacker.
Dmitri Lenev reports a privilege escalation in MySQL. MySQL evaluates arguments of suid routines in the security context of the routine's definer instead of the routine's caller, which allows remote and local authenticated users to gain privileges through a routine that has been made available using GRANT EXECUTE.
Michal Prokopiuk reports a privilege escalation in MySQL. The vulnerability causes MySQL, when run on case-sensitive filesystems, to allow remote and local authenticated users to create or access a database when the database name differs only in case from a database for which they have permissions.
The Serendipity Team reports:
Serendipity failed to correctly sanitize user input on the media manager administration page. The content of GET variables were written into JavaScript strings. By using standard string evasion techniques it was possible to execute arbitrary JavaScript.
Additionally Serendipity dynamically created a HTML form on the media manager administration page that contained all variables found in the URL as hidden fields. While the variable values were correctly escaped it was possible to break out by specifying strange variable names.
Red Hat reports:
An integer overflow flaw was found in the way Qt handled pixmap images. The KDE khtml library uses Qt in such a way that untrusted parameters could be passed to Qt, triggering the overflow. An attacker could for example create a malicious web page that when viewed by a victim in the Konqueror browser would cause Konqueror to crash or possibly execute arbitrary code with the privileges of the victim.
iDefense Labs reports:
Remote exploitation of a heap overflow vulnerability within version 9 of Opera Software's Opera Web browser could allow an attacker to execute arbitrary code on the affected host.
A flaw exists within Opera when parsing a tag that contains a URL. A heap buffer with a constant size of 256 bytes is allocated to store the URL, and the tag's URL is copied into this buffer without sufficient bounds checking of its length.
Adam Boileau of Security-Assessment.com reports:
The Asterisk Skinny channel driver for Cisco SCCP phones (chan_skinny.so) incorrectly validates a length value in the packet header. An integer wrap-around leads to heap overwrite, and arbitrary remote code execution as root.
The Plone Team reports:
Plone 2.0.5, 2.1.2, and 2.5-beta1 does not restrict access to the:
- changeMemberPortrait
- deletePersonalPortrait
- testCurrentPassword
methods, which allows remote attackers to modify portraits.
The Drupal Team reports:
A malicious user may entice users to visit a specially crafted URL that may result in the redirection of Drupal form submission to a third-party site. A user visiting the user registration page via such a url, for example, will submit all data, such as his/her e-mail address, but also possible private profile data, to a third-party site.
The Drupal Team reports:
Visiting a specially crafted page, anywhere on the web, may allow that page to post forms to a Drupal site in the context of the visitor's session. To illustrate; suppose one has an active user 1 session, the most powerful administrator account for a site, to a Drupal site while visiting a website created by an attacker. This website will now be able to submit any form to the Drupal site with the privileges of user 1, either by enticing the user to submit a form or by automated means.
An attacker can exploit this vulnerability by changing passwords, posting PHP code or creating new users, for example. The attack is only limited by the privileges of the session it executes in.
The Drupal Team reports:
A bug in input validation and lack of output validation allows HTML and script insertion on several pages.
Drupal's XML parser passes unescaped data to watchdog under certain circumstances. A malicious user may execute an XSS attack via a specially crafted RSS feed. This vulnerability exists on systems that do not use PHP's mb_string extension (to check if mb_string is being used, navigate to admin/settings and look under "String handling"). Disabling the aggregator module provides an immediate workaround.
The aggregator module, profile module, and forum module do not properly escape output of certain fields.
Note: XSS attacks may lead to administrator access if certain conditions are met.
The Horde team reports a vulnerability within Ingo, the filter management suite. The vulnerability is caused due to inadequete escaping, possibly allowing a local user to execute arbitrary shell commands via procmail.
Rapid7 reports:
The NVIDIA Binary Graphics Driver for Linux is vulnerable to a buffer overflow that allows an attacker to run arbitrary code as root. This bug can be exploited both locally or remotely (via a remote X client or an X client which visits a malicious web page). A working proof-of-concept root exploit is included with this advisory.
The NVIDIA drivers for Solaris and FreeBSD are also likely to be vulnerable.
Disabling Render acceleration in the "nvidia" driver, via the "RenderAccel" X configuration option, can be used as a workaround for this issue.
Secunia reports:
Two vulnerabilities have been reported in Clam AntiVirus, which potentially can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
1) An unspecified error in the CHM unpacker in chmunpack.c can be exploited to cause a DoS.
2) An unspecified error in rebuildpe.c when rebuilding PE files after unpacking can be exploited to cause a heap-based buffer overflow.
Javier Fernández-Sanguino Peña reports a vulnerability in tkdiff which allows local users to gain priveleges of the user running tkdiff due to insecure temporary file creation.
Dedi Dwianto a.k.a the_day reports:
Input passed to the "$calpath" parameter in update.php is not properly verified before being used. This can be exploited to execute arbitrary PHP code by including files from local or external resources.
JAAScois reports:
While processing KML/KMZ data Google Earth fails to verify its size prior to copying it into a fixed-sized buffer. This can be exploited as a buffer-overflow vulnerability to cause the application to crash and/or to execute arbitrary code.
Steven Roddis reports that User-Agent string is not properly escaped when handled by torrentflux. This allows for arbitrary code insertion.
Benjamin C. Wiley Sittler reports:
I discovered a [buffer overrun in repr() for unicode strings]. This causes an unpatched non-debug wide (UTF-32/UCS-4) build of python to abort.
Ubuntu security team reports:
If an application uses repr() on arbitrary untrusted data, this [bug] could be exploited to execute arbitrary code with the privileges of the python application.
Stefan Esser reports:
The PHP 5 branch of the PHP source code lacks the protection against possible integer overflows inside ecalloc() that is present in the PHP 4 branch and also for several years part of our Hardening-Patch and our new Suhosin-Patch.
It was discovered that such an integer overflow can be triggered when user input is passed to the unserialize() function. Earlier vulnerabilities in PHP's unserialize() that were also discovered by one of our audits in December 2004 are unrelated to the newly discovered flaw, but they have shown, that the unserialize() function is exposed to user-input in many popular PHP applications. Examples for applications that use the content of COOKIE variables with unserialize() are phpBB and Serendipity.
The successful exploitation of this integer overflow will result in arbitrary code execution.
James Bercegay reports:
Mambo is vulnerable to an Authentication Bypass issue that is due to an SQL Injection in the login function. The SQL Injection is possible because the $passwd variable is only sanitized when it is not passed as an argument to the function.
Omid reports:
There are several sql injections in Mambo 4.6 RC2 & Joomla 1.0.10 (and maybe other versions):
- When a user edits a content, the "id" parameter is not checked properly in /components/com_content/content.php, which can cause 2 sql injections.
- The "limit" parameter in the administration section is not checked. This affects many pages of administration section
- In the administration section, while editing/creating a user, the "gid" parameter is not checked properly.
Urs Janssen and Aleksey Salow report possible buffer overflows in tin versions 1.8.0 and 1.8.1.
OpenPKG project elaborates there is an allocation off-by-one bug in version 1.8.0 which can lead to a buffer overflow.
Howard Chu reports:
An ACL of the form 'access to dn.subtree="ou=groups, dc=example,dc=com" attr=member by * selfwrite' is intended to only allow users to add/delete their own DN to the target attribute. Currently it allows any DNs to be modified.
Sebastian Krahmer reports:
Sebastian Krahmer of the SuSE security team discovered that the System.CodeDom.Compiler classes used temporary files in an insecure way. This could allow a symbolic link attack to create or overwrite arbitrary files with the privileges of the user invoking the program. Under some circumstances, a local attacker could also exploit this to inject arbitrary code into running Mono processes.
Stefan Esser reports:
PHP's open_basedir feature is meant to disallow scripts to access files outside a set of configured base directories. The checks for this are placed within PHP functions dealing with files before the actual open call is performed.
Obviously there is a little span of time between the check and the actual open call. During this time span the checked path could have been altered and point to a file that is forbidden to be accessed due to open_basedir restrictions.
Because the open_basedir restrictions often not call PHP functions but 3rd party library functions to actually open the file it is impossible to close this time span in a general way. It would only be possible to close it when PHP handles the actual opening on it's own.
While it seems hard to change the path during this little time span it is very simple with the use of the symlink() function combined with a little trick. PHP's symlink() function ensures that source and target of the symlink operation are allowed by open_basedir restrictions (and safe_mode). However it is possible to point a symlink to any file by the use of mkdir(), unlink() and at least two symlinks.
Secunia reports:
ShAnKaR has discovered a vulnerability in phpBB, which can be exploited by malicious users to compromise a vulnerable system.
Input passed to the "avatar_path" parameter in admin/admin_board.php is not properly sanitised before being used as a configuration variable to store avatar images. This can be exploited to upload and execute arbitrary PHP code by changing "avatar_path" to a file with a trailing NULL byte.
Successful exploitation requires privileges to the administration section.
ISS X-Force reports:
PostNuke is vulnerable to SQL injection. A remote attacker could send specially-crafted SQL statements to the admin section using the hits parameter, which could allow the attacker to view, add, modify or delete information in the back-end database.
SecurityTracker reports:
A vulnerability was reported in FreeType. A remote user can cause arbitrary code to be executed on the target user's system.
A remote user can create a specially crafted font file that, when loaded by the target user's system, will trigger an integer underflow or integer overflow and crash the application or execute arbitrary code on the target system.
Chris Evans reported these vulnerabilities.
Impact: A remote user can create a file that, when loaded by the target user, will execute arbitrary code on the target user's system.
Secunia reports:
Will Drewry has reported some vulnerabilities in Cscope, which potentially can be exploited by malicious people to compromise a vulnerable system.
Various boundary errors within the parsing of file lists or the expansion of environment variables can be exploited to cause stack-based buffer overflows when parsing specially crafted "cscope.lists" files or directories.
A boundary error within the parsing of command line arguments can be exploited to cause a stack-based buffer overflow when supplying an overly long "reffile" argument.
Successful exploitation may allow execution of arbitrary code.
Secunia reports:
A vulnerability has been reported in GnuTLS, which can be exploited by malicious people to bypass certain security restrictions.
The vulnerability is caused due to an error in the verification of certain signatures. If a RSA key with exponent 3 is used, it may be possible to forge PKCS #1 v1.5 signatures signed with that key.
Secunia reports:
Arai has reported a vulnerability in Movable Type and Movable Type Enterprise, which can be exploited by malicious people to conduct cross-site scripting attacks.
Some unspecified input passed via the search functionality isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
phpMyAdmin team reports:
We received a security advisory from Stefan Esser (sesser@hardened-php.net) and we wish to thank him for his work.
It was possible to inject arbitrary SQL commands by forcing an authenticated user to follow a crafted link.
The CRC compensation attack detector in the sshd(8) daemon, upon receipt of duplicate blocks, uses CPU time cubic in the number of duplicate blocks received. [CVE-2006-4924]
A race condition exists in a signal handler used by the sshd(8) daemon to handle the LoginGraceTime option, which can potentially cause some cleanup routines to be executed multiple times. [CVE-2006-5051]
An attacker sending specially crafted packets to sshd(8) can cause a Denial of Service by using 100% of CPU time until a connection timeout occurs. Since this attack can be performed over multiple connections simultaneously, it is possible to cause up to MaxStartups (10 by default) sshd processes to use all the CPU time they can obtain. [CVE-2006-4924]
The OpenSSH project believe that the race condition can lead to a Denial of Service or potentially remote code execution, but the FreeBSD Security Team has been unable to verify the exact impact. [CVE-2006-5051]
The attack against the CRC compensation attack detector can be avoided by disabling SSH Protocol version 1 support in sshd_config(5).
There is no workaround for the second issue.
Secunia reports:
rgod has discovered a vulnerability in DokuWiki, which can be exploited by malicious people to compromise a vulnerable system.
Input passed to the "TARGET_FN" parameter in bin/dwpage.php is not properly sanitised before being used to copy files. This can be exploited via directory traversal attacks in combination with DokuWiki's file upload feature to execute arbitrary PHP code.

DokuWiki before 2006-03-09c enables the debug feature by default, which allows remote attackers to obtain sensitive information by calling doku.php with the X-DOKUWIKI-DO HTTP header set to "debug".
Secunia reports:
Some vulnerabilities have been reported in DokuWiki, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.
Input passed to the "w" and "h" parameters in lib/exec/fetch.php is not properly sanitised before being passed as resize parameters to the "convert" application. This can be exploited to cause a DoS due to excessive CPU and memory consumption by passing very large numbers, or to inject arbitrary shell commands by passing specially crafted strings to the "w" and "h" parameter.
Successful exploitation requires that the "$conf[imconvert]" option is set.
Secunia reports:
Thomas Pollet has discovered a vulnerability in TikiWiki, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "highlight" parameter in tiki-searchindex.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
rgod has discovered a vulnerability in TikiWiki, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to the "jhot.php" script not correctly verifying uploaded files. This can e.g. be exploited to execute arbitrary PHP code by uploading a malicious PHP script to the "img/wiki" directory.
CVE Mitre reports:
PunBB 1.2.12 does not properly handle an avatar directory pathname ending in %00, which allows remote authenticated administrative users to upload arbitrary files and execute code, as demonstrated by a query to admin_options.php with an avatars_dir parameter ending in %00. NOTE: this issue was originally disputed by the vendor, but the dispute was withdrawn on 20060926.
Secunia reports:
Luigi Auriemma has reported a vulnerability in Freeciv, which can be exploited by malicious people to cause a DoS (Denial of Service).
An error in the "generic_handle_player_attribute_chunk()" function in common/packets.c can be exploited to crash the service via a specially crafted PACKET_PLAYER_ATTRIBUTE_CHUNK packet sent to the server.
An error in the "handle_unit_orders()" function in server/unithand.c can be exploited to crash the service via a specially crafted packet.
Secunia reports:
Luigi Auriemma has reported a vulnerability in Freeciv, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error within the handling of the packet length in "common/packets.c". This can be exploited to crash the Freeciv server via a specially- crafted packet with the size set to "0xffff".
Secunia reports:
A vulnerability has been reported in Plans, which can be exploited by malicious people to conduct SQL injection attacks.
Input passed to the "evt_id" parameter in "plans.cgi" isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation requires that SQL database support has been enabled in "plans_config.pl" (the default setting is flat files).
Some vulnerabilities have been reported in Plans, which can be exploited by malicious people to conduct cross-site scripting attacks or gain knowledge of sensitive information.
Input passed to various unspecified parameters is not properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of a vulnerable site.
An unspecified error can be exploited to gain knowledge of the MySQL password.
eyeOS team reports:
[EyeOS 0.9.1] release fixes two XSS security bugs, so we recommend all users to upgrade to this new version in order to have the best security. These two bugs were discovered by Jose Carlos Norte, who is a new eyeOS developer.
Secunia reports:
A vulnerability has been reported in Zope, which can be exploited by malicious people to disclose potentially sensitive information.
The vulnerability is caused due to an error in the use of the docutils module to parse and render "restructured" text. This can be exploited to disclose certain information via the "csv_table" reStructuredText directive.
Mitre CVE reports:
Stack-based buffer overflow in libmms, as used by (a) MiMMS 0.0.9 and (b) xine-lib 1.1.0 and earlier, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via the (1) send_command, (2) string_utf16, (3) get_data, and (4) get_media_packet functions, and possibly other functions.
Opera reports:
A specially crafted digital certificate can bypass Opera's certificate signature verification. Forged certificates can contain any false information the forger chooses, and Opera will still present it as valid. Opera will not present any warning dialogs in this case, and the security status will be the highest possible (3). This defeats the protection against "man in the middle", the attacks that SSL was designed to prevent.
There is a flaw in OpenSSL's RSA signature verification that affects digital certificates using 3 as the public exponent. Some of the certificate issuers that are on Opera's list of trusted signers have root certificates with 3 as the public exponent. The forged certificate can appear to be signed by one of these.
The Mozilla Foundation reports of multiple security issues in Firefox, Seamonkey, and Thunderbird. Several of these issues can probably be used to run arbitrary code with the privilege of the user running the program.

2) An error in the processing of malformed headers which does not follow the RFC 2231 standard can be exploited to cause a DoS (Denial of Service).
3) Some unspecified input isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Kefka reports multiple cross site scripting vulnerabilities within hlstats. The vulnerabilities are caused due to improper checking of variables, allowing an attacker to perform cross site scripting.
The Debian Security Team reports:
Michael Gehring discovered several potential out-of-bounds index accesses in gtetrinet, a multiplayer Tetris-like game, which may allow a remote server to execute arbitrary code
The Joomla development team reports multiple vulnerabilities within the joomla application. Joomla is vulnerable to the following vulnerabilities:
While processing Link Control Protocol (LCP) configuration options received from the remote host, sppp(4) fails to correctly validate option lengths. This may result in data being read or written beyond the allocated kernel memory buffer.
An attacker able to send LCP packets, including the remote end of a sppp(4) connection, can cause the FreeBSD kernel to panic. Such an attacker may also be able to obtain sensitive information or gain elevated privileges.
No workaround is available, but systems which do not use sppp(4) are not vulnerable.
Secunia reports:
Some vulnerabilities have been reported in Horde, which can be exploited by malicious people to conduct phishing and cross-site scripting attacks.
- Input passed to the "url" parameter in index.php isn't properly verified before it is being used to include an arbitrary web site in a frameset. This can e.g. be exploited to trick a user into believing certain malicious content is served from a trusted web site.
- Some unspecified input passed in index.php isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The Globus Alliance reports:
The proxy generation tool (grid-proxy-init) creates the file, secures the file to provide access only to owner and writes proxy to the file. A race condition exists between the opening of the proxy credentials file, and making sure it is safe file to write to. The checks to ensure this file is accessible only to the owner take place using the filename after the file is opened for writing, but before any data is written.
Various components of the toolkit use files in shared directories to store information, some being sensitive information. For example, the tool to create proxy certificates, stores the generated proxy certificate by default in /tmp. Specific vulnerabilities in handling such files were reported in myproxy-admin-adduser, grid-ca-sign and grid-security-config.
Ludwig Nussel reports that x11vnc is vulnerable to an authentication bypass vulnerability. The vulnerability is caused by an error in auth.c. This could allow a remote attacker to gain unauthorized and unauthenticated access to the system.
Luigi Auriemma reports three vulnerabilities within alsaplayer:
- The function which handles the HTTP connections is vulnerable to a buffer-overflow that happens when it uses sscanf for copying the URL in the Location's field received from the server into the redirect buffer of only 1024 bytes declared in http_open.
- A buffer-overflow exists in the functions which add items to the playlist when the GTK interface is used (so the other interfaces are not affected by this problem): new_list_item and CbUpdated in interface/gtk/PlaylistWindow.cpp.
- AlsaPlayer automatically queries the CDDB server specified in its configuration (by default freedb.freedb.org) when the user choices the CDDA function for playing audio CDs. The function which queries the server uses a buffer of 20 bytes and one of 9 for storing the category and ID strings received from the server while the buffer which contains this server's response is 32768 bytes long. Naturally for exploiting this bug the attacker must have control of the freedb server specified in the AlsaPlayer's configuration.
These vulnerabilities could allow a remote attacker to execute arbitrary code, possibly gaining access to the system.
The PostgreSQL development team reports:
An attacker able to submit crafted strings to an application that will embed those strings in SQL commands can use invalidly-encoded multibyte characters to bypass standard string-escaping methods, resulting in possible injection of hostile SQL commands into the database. The attacks covered here work in any multibyte encoding.
The widely-used practice of escaping ASCII single quote "'" by turning it into "\'" is unsafe when operating in multibyte encodings that allow 0x5c (ASCII code for backslash) as the trailing byte of a multibyte character; this includes at least SJIS, BIG5, GBK, GB18030, and UHC. An application that uses this conversion while embedding untrusted strings in SQL commands is vulnerable to SQL-injection attacks if it communicates with the server in one of these encodings. While the standard client libraries used with PostgreSQL have escaped "'" in the safe, SQL-standard way of "''" for some time, the older practice remains common.
Multiple vulnerabilities had been reported in various versions of PostgreSQL:
Jean-David Maillefer reports a Denial of Service vulnerability
within MySQL. The vulnerability is caused by improper checking
of the data_format routine, which cause the MySQL server to
crash. The crash is triggered by the following code:
"SELECT date_format('%d%s', 1);
The SquirrelMail developers report:
A logged in user could overwrite random variables in compose.php, which might make it possible to read/write other users' preferences or attachments.
The Ruby on Rails blog reports:
With Rails 1.1.0 through 1.1.5 (minus the short-lived 1.1.3), you can trigger the evaluation of Ruby code through the URL because of a bug in the routing code of Rails. This means that you can essentially take down a Rails process by starting something like /script/profiler, as the code will run for a long time and that process will be hung while it happens. Other URLs can even cause data loss.
Clamav team reports:
A heap overflow vulnerability was discovered in libclamav which could cause a denial of service or allow the execution of arbitrary code.
The problem is specifically located in the PE file rebuild function used by the UPX unpacker.
Relevant code from libclamav/upx.c:
memcpy(dst, newbuf, foffset); *dsize = foffset; free(newbuf); cli_dbgmsg("UPX: PE structure rebuilt from compressed file\n"); return 1;
Due to improper validation it is possible to overflow the above memcpy() beyond the allocated memory block.
The Drupal project reports:
A malicious user can execute a cross site scripting attack by enticing someone to visit a Drupal site via a specially crafted link.
Author reports:
Fixed 2 more possible memory allocation attacks. They are similar to the problem we fixed with 1.4.4. This bug can easily be exploted for a DoS; remote code execution is not entirely impossible.
Secunia reports:
Two vulnerabilities have been reported in Ruby, which can be exploited by malicious people to bypass certain security restrictions.
- An error in the handling of the "alias" functionality can be exploited to bypass the safe level protection and replace methods called in the trusted level.
- An error caused due to directory operations not being properly checked can be exploited to bypass the safe level protection and close untainted directory streams.
The Apache Software Foundation and The Apache HTTP Server Project reports:
An off-by-one flaw exists in the Rewrite module, mod_rewrite, as shipped with Apache 1.3 since 1.3.28, 2.0 since 2.0.46, and 2.2 since 2.2.0.
Depending on the manner in which Apache HTTP Server was compiled, this software defect may result in a vulnerability which, in combination with certain types of Rewrite rules in the web server configuration files, could be triggered remotely. For vulnerable builds, the nature of the vulnerability can be denial of service (crashing of web server processes) or potentially allow arbitrary code execution. This issue has been rated as having important security impact by the Apache HTTP Server Security Team.
This flaw does not affect a default installation of Apache HTTP Server. Users who do not use, or have not enabled, the Rewrite module mod_rewrite are not affected by this issue. This issue only affects installations using a Rewrite rule with the following characteristics:
- The RewriteRule allows the attacker to control the initial part of the rewritten URL (for example if the substitution URL starts with $1)
- The RewriteRule flags do NOT include any of the following flags: Forbidden (F), Gone (G), or NoEscape (NE).
Please note that ability to exploit this issue is dependent on the stack layout for a particular compiled version of mod_rewrite. If the compiler used to compile Apache HTTP Server has added padding to the stack immediately after the buffer being overwritten, it will not be possible to exploit this issue, and Apache HTTP Server will continue operating normally.
The Apache HTTP Server project thanks Mark Dowd of McAfee Avert Labs for the responsible reporting of this vulnerability.
A Mozilla Foundation Security Advisory reports of multiple issues. Several of which can be used to run arbitrary code with the privilege of the user running the program.

The Drupal team reports:
Vulnerability: XSS Vulnerability in taxonomy module
It is possible for a malicious user to insert and execute XSS into terms, due to lack of validation on output of the page title. The fix wraps the display of terms in check_plain().
Goober's advisory reports reports that shoutcast is vulnerable to an arbitrary file reading vulnerability:
Impact of the vulnerability depends on the way the product was installed. In general, the vulnerability allows the attacker to read any file which can be read by the Shoutcast server process.
The Samba Team reports:
The smbd daemon maintains internal data structures used track active connections to file and printer shares. In certain circumstances an attacker may be able to continually increase the memory usage of an smbd process by issuing a large number of share connection requests. This defect affects all Samba configurations.
A TWiki Security Alert reports:
The TWiki upload filter already prevents executable scripts such as .php, .php1, .phps, .pl from potentially getting executed by appending a .txt suffix to the uploaded filename. However, PHP and some other types allows additional file suffixes, such as .php.en, .php.1, and .php.2. TWiki does not check for these suffixes, e.g. it is possible to upload php scripts with such suffixes without the .txt filename padding.
This issue can also be worked around with a restrictive web server configuration. See the TWiki Security Alert for more information about how to do this.
The Trac 0.9.6 Release Notes reports:
Fixed reStructuredText breach of privacy and denial of service vulnerability found by Felix Wiemann.
The discovered vulnerability requires docutils to be installed and enabled. Systems that do not have docutils installed or enabled are not vulnerable. As of this version version 0.3.9 or greater of docutils is required for using reStructuredText markup in Trac.
Horde 3.1.2 release announcement:
Security Fixes:

phpmyadmin Site reports:
It was possible to craft a request that contains XSS by attacking the "table" parameter.
The webmin development team reports:
An attacker without a login to Webmin can read the contents of any file on the server using a specially crafted URL. All users should upgrade to version 1.290 as soon as possible, or setup IP access control in Webmin.
SecurityFocus reports:
Mutt is prone to a remote buffer-overflow vulnerability. This issue is due to the application's failure to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.
This issue may allow remote attackers to execute arbitrary machine code in the context of the affected application. Failed exploit attempts will likely crash the application, denying further service to legitimate users.

Andreas Seltenreich reports that hashcash is prone to a heap overflow vulnerability. This vulnerability is caused by improper checking of memory allocations within the "array_push()" function. An attacker could trigger this vulnerability by passing a lot of "-r" or "-j" flags from the command line, this only applies when the application is configured to allow command line options, or by passing a lot of resource names when the application was started with the "-m" flag set. This could lead to a Denial or Service or could allow remote access to the targeted system.
If GnuPG processes a userid with a very long packet length, GnuPG can crash due to insufficient bounds check. This can result in a denial-of-service condition or potentially execution of arbitrary code with the privileges of the user running GnuPG.
FrSIRT advisory ADV-2006-2356 reports:
Multiple vulnerabilities have been identified in Horde Application Framework, which may be exploited by attackers to execute arbitrary scripting code. These flaws are due to input validation errors in the "test.php" and "templates/problem/problem.inc" scripts that do not validate the "url", "name", "email", "subject" and "message" parameters, which could be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser in the security context of an affected Web site.
Secunia reports:
socsam has discovered a vulnerability in WebCalendar, which can be exploited by malicious people to bypass certain security restrictions and disclose sensitive information.
Input passed to the "includedir" parameter isn't properly verified, before it is used in an "fopen()" call. This can be exploited to load an arbitrary setting file from an external web site.
This can further be exploited to disclose the content of arbitrary files by defining the "user_inc" variable in a malicious setting file.
Successful exploitation requires that "register_globals" is enabled.
A suitably malformed multipart MIME message can cause sendmail to exceed predefined limits on its stack usage.
An attacker able to send mail to, or via, a server can cause queued messages on the system to not be delivered, by causing the sendmail process which handles queued messages to crash. Note that this will not stop new messages from entering the queue (either from local processes, or incoming via SMTP).
No workaround is available, but systems which do not receive email from untrusted sources are not vulnerable.
Multiple vulnerabilities have been reported within dokuwiki. dokuwiki is proven vulnerable to:
A Secunia Advisory reports:
Federico L. Bossi Bonin has discovered a weakness in xine-lib, which can be exploited by malicious people to crash certain applications on a user's system.
The weakness is cause due to a heap corruption within the "xineplug_inp_http.so" plugin when handling an overly large reply from the HTTP server. This can be exploited to crash an application that uses the plugin (e.g. gxine).
smbfs does not properly sanitize paths containing a backslash character; in particular the directory name '..\' is interpreted as the parent directory by the SMB/CIFS server, but smbfs handles it in the same manner as any other directory.
When inside a chroot environment which resides on a smbfs mounted file-system it is possible for an attacker to escape out of this chroot to any other directory on the smbfs mounted file-system.
Mount the smbfs file-systems which need to be used with chroot on top, in a way so the chroot directory is exactly on the mount point and not a sub directory
There are two documented methods of restricting access to NIS maps through ypserv(8): through the use of the /var/yp/securenets file, and through the /etc/hosts.allow file. While both mechanisms are implemented in the server, a change in the build process caused the "securenets" access restrictions to be inadvertantly disabled.
ypserv(8) will not load or process any of the networks or hosts specified in the /var/yp/securenets file, rendering those access controls ineffective.
One possible workaround is to use /etc/hosts.allow for access control, as shown by examples in that file.
Another workaround is to use a firewall (e.g., ipfw(4), ipf(4), or pf(4)) to limit access to RPC functions from untrusted systems or networks, but due to the complexities of RPC, it might be difficult to create a set of firewall rules which accomplish this without blocking all access to the machine in question.
The freeradious development team reports:
Multiple issues exist with version 1.0.4, and all prior versions of the server. Externally exploitable vulnerabilities exist only for sites that use the rlm_sqlcounter module. Those sites may be vulnerable to SQL injection attacks, similar to the issues noted below. All sites that have not deployed the rlm_sqlcounter module are not vulnerable to external exploits.
The issues are:
SQL Injection attack in the rlm_sqlcounter module.
Buffer overflow in the rlm_sqlcounter module, that may cause a server crash.
Buffer overflow while expanding %t, that may cause a server crash.
The freeradius development team reports:
A validation issue exists with the EAP-MSCHAPv2 module in all versions from 1.0.0 (where the module first appeared) to 1.1.0. Insufficient input validation was being done in the EAP-MSCHAPv2 state machine. A malicious attacker could manipulate their EAP-MSCHAPv2 client state machine to potentially convince the server to bypass authentication checks. This bypassing could also result in the server crashing
The SquirrelMail Project Team reports:
A security issue has been uncovered in functions/plugin.php that could allow a remote user to access local files on the server without requiring login. This issue manifests itself if register_globals is enabled, and magic_quotes_gpc is disabled.
Stefan Esser reports:
During the evaluation of DokuWiki for a german/korean wiki of mine a flaw in DokuWiki's spellchecker was discovered, that allows injecting arbitrary PHP commands, by requesting a spellcheck on PHP commands in 'complex curly syntax'.
Because the spellchecker is written as part of the AJAX functionality of DokuWiki, it can be directly called by any website visitor, without the need for a wiki account.
The Drupal team reports:
Vulnerability: SQL injection
A security vulnerability in the database layer allowed certain queries to be submitted to the database without going through Drupal's query sanitizer.
Vulnerability: Execution of arbitrary files
Certain -- alas, typical -- configurations of Apache allows execution of carefully named arbitrary scripts in the files directory. Drupal now will attempt to automatically create a .htaccess file in your "files" directory to protect you.
MySQL reports:
An SQL-injection security hole has been found in multibyte encoding processing. An SQL-injection security hole can include a situation whereby when inserting user supplied data into a database, the user might inject his own SQL statements that the server will execute. With regards to this vulnerability discovered, when character set unaware escaping is used (e.g., addslashes() in PHP), it is possible to bypass it in some multibyte character sets (e.g., SJIS, BIG5 and GBK). As a result, a function like addslashes() is not able to prevent SQL injection attacks. It is impossible to fix this on the server side. The best solution is for applications to use character set aware escaping offered in a function like mysql_real_escape().
Workarounds:
One can use NO_BACKSLASH_ESCAPES mode as a workaround for a bug in mysql_real_escape_string(), if you cannot upgrade your server for some reason. It will enable SQL standard compatibility mode, where backslash is not considered a special character.
Secunia reports:
MySQL have some vulnerabilities, which can be exploited by malicious users to disclose potentially sensitive information and compromise a vulnerable system.
1) An error within the code that generates an error response to an invalid COM_TABLE_DUMP packet can be exploited by an authenticated client to disclosure certain memory content of the server process.
2) A boundary error within the handling of specially crafted invalid COM_TABLE_DUMP packets can be exploited by an authenticated client to cause a buffer overflow and allows arbitrary code execution.
3) An error within the handling of malformed login packets can be exploited to disclosure certain memory content of the server process in the error messages.
Esteban Martinez Fayo reports:
The FrontPage Server Extensions 2002 (included in Windows Sever 2003 IIS 6.0 and available as a separate download for Windows 2000 and XP) has a web page /_vti_bin/_vti_adm/fpadmdll.dll that is used for administrative purposes. This web page is vulnerable to cross site scripting attacks allowing an attacker to run client-side script on behalf of an FPSE user. If the victim is an administrator, the attacker could take complete control of a Front Page Server Extensions 2002 server.
To exploit the vulnerability an attacker can send a specially crafted e-mail message to a FPSE user and then persuade the user to click a link in the e-mail message.
In addition, this vulnerability can be exploited if an attacker hosts a malicious website and persuade the user to visit it.
Jason Duell reports:
Cscope contains an alarming number of buffer overflow vulnerabilities. By a rough count, there are at least 48 places where we blindly sprintf() a file name into a fixed-length buffer of size PATHLEN without checking to see if the file's name is <= PATHLEN. We do similar things with environment variable values.
Secunia reports:
Coppermine Photo Gallery have a vulnerability, which can be exploited by malicious users to compromise a vulnerable system.
The vulnerability is caused due to an error in the handling of file uploads where a filename has multiple file extensions. This can be exploited to upload malicious script files inside the web root (e.g. a PHP script).
Successful exploitation may allow execution of script code depending on the HTTP server configuration (it requires e.g. an Apache server with the "mod_mime" module installed).
Secunia reports:
Coppermine Photo Gallery have a vulnerability, which can be exploited by malicious people to disclose sensitive information.
Input passed to the "file" parameter in "index.php" isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources.
Example: http://[host]/index.php?file=.//././/././/././/./[file]%00
Successful exploitation requires that "magic_quotes_gpc" is disabled.
Secunia reports:
Coppermine Photo Gallery have a vulnerability, which can be exploited by malicious people and by malicious users to compromise a vulnerable system.
1) Input passed to the "lang" parameter in include/init.inc.php isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources. The vulnerability can be further exploited by users who are allowed to upload image files to execute arbitrary PHP code.
2) Input passed to the "f" parameter in docs/showdoc.php isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources on the Windows platform, and remote files from Windows shared folders.
phpMyAdmin security team reports:
It was possible to inject arbitrary SQL commands by forcing an authenticated user to follow a crafted link.
Such issue is quite common in many PHP applications and users should take care what links they follow. We consider these vulnerabilities to be quite dangerous.
RealVNC is susceptible to an authentication-bypass vulnerability. A malicious VNC client can cause a VNC server to allow it to connect without any authentication regardless of the authentication settings configured in the server. Exploiting this issue allows attackers to gain unauthenticated, remote access to the VNC servers.
Secunia reports:
phpLDAPadmin have some vulnerabilities, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to conduct cross-site scripting attacks.
1) Some input isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) Input passed to the "Container DN", "Machine Name", and "UID Number" parameters in "template_engine.php" isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed.
JVN reports:
FreeStyleWiki has XSS vulnerability.
Stefano Di Paola reports:
An authenticated user could remotely execute arbitrary commands by taking advantage of a stack overflow.
To take advantage of these flaws an attacker should have direct access to MySQL server communication layer (port 3306 or unix socket). But if used in conjuction with some web application flaws (i.e. php code injection) an attacker could use socket programming (i.e. php sockets) to gain access to that layer.
OS Reviews reports:
If the update of the stats via web front-end is allowed, a remote attacker can execute arbitrary code on the server using a specially crafted request involving the migrate parameter. Input starting with a pipe character ("|") leads to an insecure call to Perl's open function and the rest of the input being executed in a shell. The code is run in the context of the process running the AWStats CGI.
Arbitrary code can be executed by uploading a specially crafted configuration file if an attacker can put a file on the server with chosen file name and content (e.g. by using an FTP account on a shared hosting server). In this configuration file, the LogFile directive can be used to execute shell code following a pipe character. As above, an open call on unsanitized input is the source of this vulnerability.
Secunia reports:
phpWebFTP have a vulnerability, which can be exploited by malicious people to disclose sensitive information.
Input passed to the "language" parameter in index.php isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources.
Successful exploitation requires that "magic_quotes_gpc" is disabled.
A Mozilla Foundation Security Advisory reports for deleted object reference when designMode="on"
Martijn Wargers and Nick Mott each described crashes that were discovered to ultimately stem from the same root cause: attempting to use a deleted controller context when designMode was turned on. This generally results in crashing the browser, but in theory references to deleted objects can be abused to run malicious code.
"splices" reported the same crash at the fan site MozillaZine and on Bugtraq, incorrectly describing it as a buffer overflow.
Secunia reports:
A vulnerability has been reported, which can be exploited by malicious people to conduct script insertion attacks.
Input passed using the wiki macro isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed.
Secunia reports:
A vulnerability has been reported in ClamAV, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the HTTP client in the Freshclam command line utility. This can be exploited to cause a stack-based buffer overflow when the HTTP headers received from a web server exceeds 8KB.
Successful exploitation requires that Freshclam is used to download virus signature updates from a malicious mirror web server e.g. via DNS poisoning.
Secunia reports:
A vulnerability has been reported in jabberd, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error within the handling of SASL negotiation. This can be exploited to cause a crash by sending a "response" stanza before an "auth" stanza.
Secunia reports:
Cacti have a security issue, which can be exploited by malicious people to execute arbitrary SQL code and potentially compromise a vulnerable system.
The problem is caused due to the presence of the insecure "server.php" test script.
Secunia reports:
Amaya have two vulnerabilities, which can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to boundary errors within the parsing of various attribute values. This can be exploited to cause stack-based buffer overflows when a user opens a specially crafted HTML document containing certain tags with overly long attribute values.
Successful exploitation allows execution of arbitrary code.
Secunia reports:
A security issue has been discovered in LifeType, which can be exploited by malicious people to execute arbitrary SQL code and potentially compromise a vulnerable system.
The problem is caused due to the presence of the insecure "server.php" test script.
Secunia reports:
Multiple vulnerabilities have been reported in Ethereal, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
The vulnerabilities are caused due to various types of errors including boundary errors, an off-by-one error, an infinite loop error, and several unspecified errors in a multitude of protocol dissectors.
Successful exploitation causes Ethereal to stop responding, consume a large amount of system resources, crash, or execute arbitrary code.
Emmanouel Kellenis reports a denial of service vulnerability within asterisk. The vulnerability is caused by a buffer overflow in "format_jpeg.c". A large JPEG image could trigger this bug, potentially allowing a local attacker to execute arbitrary code.
Gentoo reports:
Andrea Barisani of Gentoo Linux discovered xzgv and zgv allocate insufficient memory when rendering images with more than 3 output components, such as images using the YCCK or CMYK colour space. When xzgv or zgv attempt to render the image, data from the image overruns a heap allocated buffer.
An attacker may be able to construct a malicious image that executes arbitrary code with the permissions of the xzgv or zgv user when attempting to render the image.
FRSIRT reports:
A vulnerability has been identified in CrossFire, which could be exploited by remote attackers to execute arbitrary commands or cause a denial of service. This flaw is due to a buffer overflow error in the "oldsocketmode" module that fails to properly handle overly large requests, which could be exploited by a malicious client to crash or compromise a vulnerable system.
Javier Fernández-Sanguino Peña reports:
The DBI library, the Perl5 database interface, creates a temporary PID file in an insecure manner. This can be exploited by a malicious user to overwrite arbitrary files owned by the person executing the parts of the library.
Dedi Dwianto reports:
A remote user can access the file directly to cause the system to display an error message that indicates the installation path. The resulting error message will disclose potentially sensitive installation path information to the remote attacker.
c0ntexb reports:
There are 2 format string bugs in the latest version of Xine that could be exploited by a malicious person to execute code on the system of a remote user running the media player against a malicious playlist file. By passing a format specifier in the path of a file that is embedded in a remote playlist, it is possible to trigger this bug.
Unspecified vulnerability in the CMU Cyrus Simple Authentication and Security Layer (SASL) library, has unknown impact and remote unauthenticated attack vectors, related to DIGEST-MD5 negotiation.
On "7th generation" and "8th generation" processors manufactured by AMD, including the AMD Athlon, Duron, Athlon MP, Athlon XP, Athlon64, Athlon64 FX, Opteron, Turion, and Sempron, the fxsave and fxrstor instructions do not save and restore the FOP, FIP, and FDP registers unless the exception summary bit (ES) in the x87 status word is set to 1, indicating that an unmasked x87 exception has occurred.
This behaviour is consistent with documentation provided by AMD, but is different from processors from other vendors, which save and restore the FOP, FIP, and FDP registers regardless of the value of the ES bit. As a result of this discrepancy remaining unnoticed until now, the FreeBSD kernel does not restore the contents of the FOP, FIP, and FDP registers between context switches.
On affected processors, a local attacker can monitor the execution path of a process which uses floating-point operations. This may allow an attacker to steal cryptographic keys or other sensitive information.
No workaround is available, but systems which do not use AMD Athlon, Duron, Athlon MP, Athlon XP, Athlon64, Athlon64 FX, Opteron, Turion, or Sempron processors are not vulnerable.
Secunia reports:
The vulnerability is caused due to missing security declarations in "changeMemberPortrait" and "deletePersonalPortrait". This can be exploited to manipulate or delete another user's portrait via the "member_id" parameter.
A Mozilla Foundation Security Advisory reports of multiple issues. Several of which can be used to run arbitrary code with the privilege of the user running the program.

Secunia reports:
A vulnerability has been reported in Mailman, which can be exploited by malicious people to conduct cross-site scripting attacks.
Unspecified input passed to the private archive script is not properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of a vulnerable site.
Javier Fernández-Sanguino Peña reports two temporary file vulnerability within f2c. The vulnerabilities are caused due to weak temporary file handling. An attacker could create an symbolic link, causing a local user running f2c to overwrite the symlinked file. This could give the attacker elevated privileges.
Secunia reports:
The vulnerabilities are caused due to integer overflow errors in "libmpdemux/asfheader.c" within the handling of an ASF file, and in "libmpdemux/aviheader.c" when parsing the "indx" chunk in an AVI file. This can be exploited to cause heap-based buffer overflows via a malicious ASF file, or via a AVI file with specially-crafted "wLongsPerEntry" and "nEntriesInUse" values in the "indx" chunk.
The KDE team reports:
Kaffeine can produce a buffer overflow in http_peek() while creating HTTP request headers for fetching remote playlists, which under certain circumstances could be used to crash the application and/or execute arbitrary code.
Renaud Lifchitz reports a vulnerability within thunderbird. The vulnerability is caused by improper checking of javascript scripts. This could lead to javascript code execution which can lead to information disclosure or a denial of service (application crash). This vulnerability is present even if javascript had been disabled in the preferences.
phpMyAdmin security announcement:
It was possible to conduct an XSS attack with a direct call to some scripts under the themes directory.
Secunia reports:
A vulnerability has been reported in phpMyAdmin, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "set_theme" parameter isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Secunia reports:
Some vulnerabilities have been reported in ClamAV, which potentially can be exploited by malicious people to cause a DoS (Denial of Service) and compromise a vulnerable system.
An unspecified integer overflow error exists in the PE header parser in "libclamav/pe.c". Successful exploitation requires that the ArchiveMaxFileSize option is disabled.
Some format string errors in the logging handling in "shared/output.c" may be exploited to execute arbitrary code.
An out-of-bounds memory access error in the "cli_bitset_test()" function in "ibclamav/others.c" may be exploited to cause a crash.
The mediawiki development team reports a vulnerability within the mediawiki application. The vulnerability is caused by improper checking of inline style attributes. This could result in the execution of arbitrary javascript code in Microsoft Internet Explorer. It appears that other browsers are not affected by this vulnerability.
Ubuntu reports:
A buffer overflow was found in the "pnmtopng" conversion program. By tricking an user (or automated system) to process a specially crafted PNM image with pnmtopng, this could be exploited to execute arbitrary code with the privileges of the user running pnmtopng.
Jean-Sébastien Guay-Leroux report a vulnerability within the zoo archiver. The vulnerability which is present in the fullpath() function (from the misc.c file) is caused by improper checking of user supplied data. The data returned to the buffer can be up to 512 bytes, while the buffer is created to hold 256 bytes. This could result in a buffer overflow which could allow remote code execution.
The mediawiki development team reports that there is an site scripting vulnerability within mediawiki. The vulnerability is caused by improper checking of encoded links which could allow the injection of html in the output generated by mediawiki. This could lead to cross site scripting attacks against mediawiki installations.
Secunia reports:
Some vulnerabilities have been reported in Dia, which potentially can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to boundary errors within the XFig import plugin. This can be exploited to cause buffer overflows and may allow arbitrary code execution when a specially-crafted FIG file is imported.
Hendrik Weimer reports:
OpenVPN clients are a bit too generous when accepting configuration options from a server. It is possible to transmit environment variables to client-side shell scripts. There are some filters in place to prevent obvious nonsense, however they don't catch the good old LD_PRELOAD trick. All we need is to put a file onto the client under a known location (e.g. by returning a specially crafted document upon web access) and we have a remote root exploit. But since the attack may only come from authenticated servers, this threat is greatly reduced.
Samba Security Advisory:
The machine trust account password is the secret shared between a domain controller and a specific member server. Access to the member server machine credentials allows an attacker to impersonate the server in the domain and gain access to additional information regarding domain users and groups.
The winbindd daemon writes the clear text of server's machine credentials to its log file at level 5. The winbindd log files are world readable by default and often log files are requested on open mailing lists as tools used to debug server misconfigurations.
This affects servers configured to use domain or ads security and possibly Samba domain controllers as well (if configured to use winbindd).
Nathan Dors of the Pubcookie Project reports:
Non-persistent XSS vulnerabilities were found in the Pubcookie Apache module (mod_pubcookie) and ISAPI filter. These components mishandle untrusted data when printing responses to the browser. This makes them vulnerable to carefully crafted requests containing script or HTML. If an attacker can lure an unsuspecting user to visit carefully staged content, the attacker can use it to redirect the user to a vulnerable Pubcookie application server and attempt to exploit the XSS vulnerabilities.
These vulnerabilities are classified as *high* due to the nature and purpose of Pubcookie application servers for user authentication and Web Single Sign-on (SSO). An attacker who injects malicious script through the vulnerabilities might steal private Pubcookie data including a user's authentication assertion ("granting") cookies and application session cookies.
Nathan Dors of the Pubcookie Project reports:
Multiple non-persistent XSS vulnerabilities were found in the Pubcookie login server's compiled binary "index.cgi" CGI program. The CGI program mishandles untrusted data when printing responses to the browser. This makes the program vulnerable to carefully crafted requests containing script or HTML. If an attacker can lure an unsuspecting user to visit carefully staged content, the attacker can use it to redirect the user to his or her local Pubcookie login page and attempt to exploit the XSS vulnerabilities.
These vulnerabilities are classified as *critical* due to the nature and purpose of the Pubcookie login server for user authentication and Web Single Sign-on (SSO). Specific threats include:
- An attacker who injects malicious script through the vulnerabilities might steal senstive user data including a user's authentication credentials (usernames and passwords);
- An attacker who injects malicious script through the vulnerabilities might steal private Pubcookie data including a user's authentication assertion ("granting") cookies and SSO ("login") session cookies;
- An attacker who injects HTML tags through the vulnerabilities might deface a site's Pubcookie login page for a single visit by a single user (i.e. a non-persistent defacement).
At the heart of these threats lies a violation of the user's trust in the Pubcookie login server.
Freeradius Security Contact reports:
Insufficient input validation was being done in the EAP-MSCHAPv2 state machine. A malicious attacker could manipulate their EAP-MSCHAPv2 client state machine to potentially convince the server to bypass authentication checks. This bypassing could also result in the server crashing.
Horde 3.1.1 release announcement:
Major changes compared to Horde 3.1 are:
- Fix for remote code execution vulnerability in the help viewer, discovered by Jan Schneider from the Horde team.
Secunia Advisories Reports:
A boundary error when processing SWF files can be exploited to cause a buffer overflow. This may allow execution of arbitrary code on the user's system.
iDefense Reports:
Remote exploitation of a heap-based buffer overflow in RealNetwork Inc's RealPlayer could allow the execution of arbitrary code in the context of the currently logged in user.
In order to exploit this vulnerability, an attacker would need to entice a user to follow a link to a malicious server. Once the user visits a website under the control of an attacker, it is possible in a default install of RealPlayer to force a web-browser to use RealPlayer to connect to an arbitrary server, even when it is not the default application for handling those types, by the use of embedded object tags in a webpage. This may allow automated exploitation when the page is viewed.
A race condition has been reported to exist in the handling by sendmail of asynchronous signals.
A remote attacker may be able to execute arbitrary code with the privileges of the user running sendmail, typically root.
There is no known workaround other than disabling sendmail.
The opiepasswd(1) program uses getlogin(2) to identify the user calling opiepasswd(1). In some circumstances getlogin(2) will return "root" even when running as an unprivileged user. This causes opiepasswd(1) to allow an unpriviled user to configure OPIE authentication for the root user.
In certain cases an attacker able to run commands as a non privileged users which have not explicitly logged in, for example CGI scripts run by a web server, is able to configure OPIE access for the root user. If the attacker is able to authenticate as root using OPIE authentication, for example if "PermitRootLogin" is set to "yes" in sshd_config or the attacker has access to a local user in the "wheel" group, the attacker can gain root privileges.
Disable OPIE authentication in PAM:
# sed -i "" -e /opie/s/^/#/ /etc/pam.d/*
or
Remove the setuid bit from opiepasswd:
# chflags noschg /usr/bin/opiepasswd
# chmod 555 /usr/bin/opiepasswd
# chflags schg /usr/bin/opiepasswd
IPsec provides an anti-replay service which when enabled prevents an attacker from successfully executing a replay attack. This is done through the verification of sequence numbers. A programming error in the fast_ipsec(4) implementation results in the sequence number associated with a Security Association not being updated, allowing packets to unconditionally pass sequence number verification checks.
An attacker able to intercept IPSec packets can replay them. If higher level protocols which do not provide any protection against packet replays (e.g., UDP) are used, this may have a variety of effects.
No workaround is available.
Daniel Stone of X.Org reports:
During the analysis of results from the Coverity code review of X.Org, we discovered a flaw in the server that allows local users to execute arbitrary code with root privileges, or cause a denial of service by overwriting files on the system, again with root privileges.
A Project heimdal Security Advisory reports:
The telnet client program in Heimdal has buffer overflows in the functions slc_add_reply() and env_opt_add(), which may lead to remote code execution.
The telnetd server program in Heimdal has buffer overflows in the function getterminaltype, which may lead to remote code execution.
The rshd server in Heimdal has a privilege escalation bug when storing forwarded credentials. The code allowes a user to overwrite a file with its credential cache, and get ownership of the file.
A Project cURL Security Advisory reports:
libcurl uses the given file part of a TFTP URL in a manner that allows a malicious user to overflow a heap-based memory buffer due to the lack of boundary check.
This overflow happens if you pass in a URL with a TFTP protocol prefix ("tftp://"), using a valid host and a path part that is longer than 512 bytes.
The affected flaw can be triggered by a redirect, if curl/libcurl is told to follow redirects and an HTTP server points the client to a tftp URL with the characteristics described above.
Drupal reports:
Mail header injection vulnerability.
Linefeeds and carriage returns were not being stripped from email headers, raising the possibility of bogus headers being inserted into outgoing email.
This could lead to Drupal sites being used to send unwanted email.
Session fixation vulnerability.
If someone creates a clever enough URL and convinces you to click on it, and you later log in but you do not log off then the attacker may be able to impersonate you.
XSS vulnerabilities.
Some user input sanity checking was missing. This could lead to possible cross-site scripting (XSS) attacks.
XSS can lead to user tracking and theft of accounts and services.
Security bypass in menu.module.
If you use menu.module to create a menu item, the page you point to will be accessible to all, even if it is an admin page.
Secunia advisory SA19246:
Paul Craig has discovered a vulnerability in Horde, which can be exploited by malicious people to disclose sensitive information. Input passed to the "url" parameter in "services/go.php" isn't properly verified, before it is used in a "readfile()" call. This can be exploited to disclose the content of arbitrary files via e.g. the "php://" protocol wrapper.
The vulnerability has been confirmed in version 3.0.9 and has also been reported in prior versions.
Provided and/or discovered by: Paul Craig, Security-Assessment.com.
Adobe reports:
Critical vulnerabilities have been identified in Flash Player that could allow an attacker who successfully exploits these vulnerabilities to take control of the affected system. A malicious SWF must be loaded in Flash Player by the user for an attacker to exploit these vulnerabilities.
Flash Player 8 update (8.0.24.0), and Flash Player 7 update (7.0.63.0) address security vulnerabilities in previous versions of Flash Player, which could lead to the potential execution of arbitrary code. These vulnerabilities could be accessed through content delivered from a remote location via the users web browser, email client, or other applications that include or reference the Flash Player.
A part of the NFS server code charged with handling incoming RPC messages via TCP had an error which, when the server received a message with a zero-length payload, would cause a NULL pointer dereference which results in a kernel panic. The kernel will only process the RPC messages if a userland nfsd daemon is running.
The NULL pointer deference allows a remote attacker capable of sending RPC messages to an affected FreeBSD system to crash the FreeBSD system.
Disable the NFS server: set the nfs_server_enable variable to "NO" in /etc/rc.conf, and reboot.
Alternatively, if there are no active NFS clients (as listed by the showmount(8) utility), simply killing the mountd and nfsd processes should suffice.
Add firewall rules to block RPC traffic to the NFS server from untrusted hosts.
Because OpenSSH and OpenPAM have conflicting designs (one is event- driven while the other is callback-driven), it is necessary for OpenSSH to fork a child process to handle calls to the PAM framework. However, if the unprivileged child terminates while PAM authentication is under way, the parent process incorrectly believes that the PAM child also terminated. The parent process then terminates, and the PAM child is left behind.
Due to the way OpenSSH performs internal accounting, these orphaned PAM children are counted as pending connections by the master OpenSSH server process. Once a certain number of orphans has accumulated, the master decides that it is overloaded and stops accepting client connections.
By repeatedly connecting to a vulnerable server, waiting for a password prompt, and closing the connection, an attacker can cause OpenSSH to stop accepting client connections until the system restarts or an administrator manually kills the orphaned PAM processes.
The following command will show a list of orphaned PAM processes:
# pgrep -lf 'sshd.*\[pam\]'
The following command will kill orphaned PAM processes:
# pkill -f 'sshd.*\[pam\]'
To prevent OpenSSH from leaving orphaned PAM processes behind, perform one of the following:
Disable PAM authentication in OpenSSH. Users will still be able to log in using their Unix password, OPIE or SSH keys.
To do this, execute the following commands as root:
# echo 'UsePAM no' >>/etc/ssh/sshd_config
# echo 'PasswordAuthentication yes' >>/etc/ssh/sshd_config
# /etc/rc.d/sshd restart
If disabling PAM is not an option - if, for instance, you use RADIUS authentication, or store user passwords in an SQL database - you may instead disable privilege separation. However, this may leave OpenSSH vulnerable to hitherto unknown bugs, and should be considered a last resort.
To do this, execute the following commands as root:
# echo 'UsePrivilegeSeparation no' >>/etc/ssh/sshd_config
# /etc/rc.d/sshd restart
Werner Koch reports:
In the aftermath of the false positive signature verfication bug (announced 2006-02-15) more thorough testing of the fix has been done and another vulnerability has been detected. This new problem affects the use of *gpg* for verification of signatures which are _not_ detached signatures. The problem also affects verification of signatures embedded in encrypted messages; i.e. standard use of gpg for mails.
The Mplayer team reports:
A potential buffer overflow was found in the ASF demuxer. Arbitrary remote code execution is possible (under the user ID running the player) when streaming an ASF file from a malicious server or local code execution (under the user ID running the player) if a malicious ASF file is played locally.
SSH Communications Security Corp reports a format string vulnerability in their SFTP server. This vulnerability could cause a user with SCP/SFTP access only to get permission to execute also other commands. It could also allow user A to create a special file that when accessed by user B allows user A to execute commands as user B.
GNU tar is vulnerable to a buffer overflow, caused by improper bounds checking of the PAX extended headers. By tricking an user into processing a specially crafted tar archive, this could be exploited to execute arbitrary code with the privileges of the user.
Some vulnerabilities have been reported in Bugzilla, which can be exploited by malicious users to conduct SQL injection attacks, and by malicious people to disclose sensitive information and conduct script insertion attacks.
Multiple vulnerabilities has been discovered since 1.4.5, including IMAP injection as well as some XSS issues.
Yan Feng reports a format string vulnerability in gedit. This vulnerability could cause a denial of service with a binary file that contains format string characters within the filename. It had been reported that web browsers and email clients can be configured to provide a filename as an argument to gedit.:
SecurityFocus reports that WebCalendar is affected by an unauthorized access vulnerability. The vulnerability is caused by improper checking of the authentication mechanism before access is being permitted to the "assistant_edit.php" file.
Chris Evans reports that AbiWord is vulnerable to multiple stack-based buffer overflow vulnerabilities. This is caused by improper checking of the user-supplied data before it is being copied to an too small buffer. The vulnerability is triggered when someone is importing RTF files.
The PostgreSQL team reports:
Due to inadequate validity checking, a user could exploit the special case that SET ROLE normally uses to restore the previous role setting after an error. This allowed ordinary users to acquire superuser status, for example.
Werner Koch reports:
The Gentoo project identified a security related bug in GnuPG. When using any current version of GnuPG for unattended signature verification (e.g. by scripts and mail programs), false positive signature verification of detached signatures may occur.
This problem affects the tool *gpgv*, as well as using "gpg --verify" to imitate gpgv, if only the exit code of the process is used to decide whether a detached signature is valid. This is a plausible mode of operation for gpgv.
If, as suggested, the --status-fd generated output is used to decide whether a signature is valid, no problem exists. In particular applications making use of the GPGME library[2] are not affected.
Pizzashack reports:
Max Vozeler has reported a problem whereby rssh can allow users who have shell access to systems where rssh is installed (and rssh_chroot_helper is installed SUID) to gain root access to the system, due to the ability to chroot to arbitrary locations. There are a lot of potentially mitigating factors, but to be safe you should upgrade immediately.
Roger Dingledine reports:
If you offer a Tor hidden service, an adversary who can run a fast Tor server and who knows some basic statistics can find the location of your hidden service in a matter of minutes to hours.
Tavis Ormandy reports:
The bash shell uses the value of the PS4 environment variable (after expansion) as a prefix for commands run in execution trace mode. Execution trace mode (xtrace) is normally set via bash's -x command line option or interactively by running "set -o xtrace". However, it may also be enabled by placing the string "xtrace" in the SHELLOPTS environment variable before bash is started.
A malicious user with sudo access to a shell script that uses bash can use this feature to run arbitrary commands for each line of the script.
The Secure Science Corporation reports that libtomcrypt is vulnerable to a weak signature scheme. This allows an attacker to create a valid random signature and use that to sign arbitrary messages without requiring the private key.
r0t reports:
Mantis contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to "target_field" parameter in "view_filters_page.php" is not properly sanitised before being returned to the user. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Multiple vulnerabilities have been reported within phpbb. phpbb is proven vulnerable to:
The postgresql development team reports:
The more severe of the two errors is that the functions that support client-to-server character set conversion can be called from SQL commands by unprivileged users, but these functions are not designed to be safe against malicious choices of argument values. This problem exists in PostgreSQL 7.3.* through 8.0.*. The recommended fix is to disable public EXECUTE access for these functions. This does not affect normal usage of the functions for character set conversion, but it will prevent misuse.
The other error is that the contrib/tsearch2 module misdeclares several functions as returning type "internal" when they do not have any "internal" argument. This breaks the type safety of "internal" by allowing users to construct SQL commands that invoke other functions accepting "internal" arguments. The consequences of this have not been investigated in detail, but it is certainly at least possible to crash the backend.
Eric Romang reports a temporary file creation vulnerability within heartbeat. The vulnerability is caused by hardcoded temporary file usage. This can cause an attacker to create an arbitrary symlink causing the application to overwrite the symlinked file with the permissions of the user executing the application.
The KDE team reports:
kpdf, the KDE pdf viewer, shares code with xpdf. xpdf contains a heap based buffer overflow in the splash rasterizer engine that can crash kpdf or even execute arbitrary code.
The Perl Development page reports:
Dyad Security recently released a security advisory explaining how in certain cases, a carefully crafted format string passed to sprintf can cause a buffer overflow. This buffer overflow can then be used by an attacker to execute code on the machine. This was discovered in the context of a design problem with the Webmin administration package that allowed a malicious user to pass unchecked data into sprintf.
Francesco Ongaro reports that phpicalendar is vulnerable for a cross site scripting attack. The vulnerability is caused by improper validation of the index.php file allowing attackers to include an arbitrary file with the .php extension
The phpicalendar team reports that there is an unspecified vulnerability within phpicalendar. This seems to be a file disclosure vulnerability caused by improper checking of the template parsing function. This would allow an attacker to disclose any file readable by the user under which the webserver runs.
Problem description:
When insufficient memory is available to handle an incoming selective acknowledgement, the TCP/IP stack may enter an infinite loop.
Impact:
By opening a TCP connection and sending a carefully crafted series of packets, an attacker may be able to cause a denial of service.
Workaround:
On FreeBSD 5.4, the net.inet.tcp.sack.enable sysctl can be used to disable the use of SACK:
# sysctl net.inet.tcp.sack.enable=0
No workaround is available for FreeBSD 5.3.
Problem description:
A logic bug in pf's IP fragment cache may result in a packet fragment being inserted twice, violating a kernel invariant.
Impact:
By sending carefully crafted sequence of IP packet fragments, a remote attacker can cause a system running pf with a ruleset containing a 'scrub fragment crop' or 'scrub fragment drop-ovl' rule to crash.
Workaround:
Do not use 'scrub fragment crop' or 'scrub fragment drop-ovl' rules on systems running pf. In most cases, such rules can be replaced by 'scrub fragment reassemble' rules; see the pf.conf(5) manual page for more details.
Systems which do not use pf, or use pf but do not use the aforementioned rules, are not affected by this issue.
Problem description:
A buffer allocated from the kernel stack may not be completely initialized before being copied to userland. [CVE-2006-0379]
A logic error in computing a buffer length may allow too much data to be copied into userland. [CVE-2006-0380]
Impact:
Portions of kernel memory may be disclosed to local users. Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way. For example, a terminal buffer might include a user-entered password.
Workaround:
No workaround is available.
Problem description:
An integer overflow in the handling of corrupt IEEE 802.11 beacon or probe response frames when scanning for existing wireless networks can result in the frame overflowing a buffer.
Impact:
An attacker able broadcast a carefully crafted beacon or probe response frame may be able to execute arbitrary code within the context of the FreeBSD kernel on any system scanning for wireless networks.
Workaround:
No workaround is available, but systems without IEEE 802.11 hardware or drivers loaded are not vulnerable.
Problem description:
The firewall maintains a pointer to layer 4 header information in the event that it needs to send a TCP reset or ICMP error message to discard packets. Due to incorrect handling of IP fragments, this pointer fails to get initialized.
Impact:
An attacker can cause the firewall to crash by sending ICMP IP fragments to or through firewalls which match any reset, reject or unreach actions.
Workaround:
Change any reset, reject or unreach actions to deny. It should be noted that this will result in packets being silently discarded.
Mitre CVE reports:
Format string vulnerability in main.cpp in kpopup 0.9.1-0.9.5pre2 allows local users to cause a denial of service (segmentation fault) and possibly execute arbitrary code via format string specifiers in command line arguments.
misc.cpp in KPopup 0.9.1 trusts the PATH variable when executing killall, which allows local users to elevate their privileges by modifying the PATH variable to reference a malicious killall program.

Problem description:
A number of issues has been discovered in cpio:
When creating a new file, cpio closes the file before setting its permissions. (CVE-2005-1111)
When extracting files cpio does not properly sanitize file names to filter out ".." components, even if the --no-absolute-filenames option is used. (CVE-2005-1229)
When adding large files (larger than 4 GB) to a cpio archive on 64-bit platforms an internal buffer might overflow. (CVE-2005-4268)
Impact
The first problem can allow a local attacker to change the permissions of files owned by the user executing cpio providing that they have write access to the directory in which the file is being extracted. (CVE-2005-1111)
The lack of proper file name sanitation can allow an attacker to overwrite arbitrary local files when extracting files from a cpio archive. (CVE-2005-1229)
The buffer-overflow on 64-bit platforms could lead cpio to a Denial-of-Service situation (crash) or possibly execute arbitrary code with the permissions of the user running cpio. (CVE-2005-4268)
Workaround
Use a different utility to create and extract cpio archives, for example pax(1) or (on FreeBSD 5.3 or later) tar(1). If this is not possible, do not extract untrusted archives and when running on 64-bit platforms do not add untrusted files to cpio archives.
Problem description
The ispell_op function used by ee(1) while executing spell
check operations employs an insecure method of temporary file
generation. This method produces predictable file names based
on the process ID and fails to confirm which path will be over
written with the user.
It should be noted that ispell does not have to be installed
in order for this to be exploited. The option simply needs to
be selected.
Impact
These predictable temporary file names are problematic because they allow an attacker to take advantage of a race condition in order to execute a symlink attack, which could allow them to overwrite files on the system in the context of the user running the ee(1) editor.
Workaround
Instead of invoking ispell through ee(1), invoke it directly.
Problem description
The "sort_offline" function used by texindex(1) employs the "maketempname" function, which produces predictable file names and fails to validate that the paths do not exist.
Impact
These predictable temporary file names are problematic because they allow an attacker to take advantage of a race condition in order to execute a symlink attack, which could enable them to overwrite files on the system in the context of the user running the texindex(1) utility.
Workaround
No workaround is available, but the problematic code is only executed if the input file being processed is 500kB or more in length; as a result, users working with documents of less than several hundred pages are very unlikely to be affected.
Problem description
A temporary file is created, used, deleted, and then
re-created with the same name. This creates a window during
which an attacker could replace the file with a link to
another file. While cvsbug(1) is based on the send-pr(1)
utility, this problem does not exist in the version of
send-pr(1) distributed with FreeBSD.
In FreeBSD 4.10 and 5.3, some additional problems exist
concerning temporary file usage in both cvsbug(1) and
send-pr(1).
Impact
A local attacker could cause data to be written to any file to which the user running cvsbug(1) (or send-pr(1) in FreeBSD 4.10 and 5.3) has write access. This may cause damage in itself (e.g., by destroying important system files or documents) or may be used to obtain elevated privileges.
Workaround
Do not use the cvsbug(1) utility on any system with untrusted
users.
Do not use the send-pr(1) utility on a FreeBSD 4.10 or 5.3
system with untrusted users.
Sun Microsystems reports:
The SGE 6.0u7_1 release fixes a security bug which can allow malicious users to gain root access.
Matthias Andree reports:
Fetchmail contains a bug that causes itself to crash when bouncing a message to the originator or to the local postmaster. The crash happens after the bounce message has been sent, when fetchmail tries to free the dynamic array of failed addresses, and calls the free() function with an invalid pointer.
The Zero Day Initiative reports:
This vulnerability allows remote attackers to execute arbitrary code on vulnerable Clam AntiVirus installations. Authentication is not required to exploit this vulnerability.
This specific flaw exists within libclamav/upx.c during the unpacking of executable files compressed with UPX. Due to an invalid size calculation during a data copy from the user-controlled file to heap allocated memory, an exploitable memory corruption condition is created.
Juan J. Marítnez reports:
The milter crashes while processing a headerless message
Impact: bogom crashes and sendmail moves it to error state
Matthias Andree reports:
Bogofilter's/bogolexer's input handling in version 0.96.2 was not keeping track of its output buffers properly and could overrun a heap buffer if the input contained words whose length exceeded 16,384 bytes, the size of flex's input buffer. A "word" here refers to a contiguous run of input octets that was not '_' and did not match at least one of ispunct(), iscntrl() or isspace().
Matthias Andree reports:
When using Unicode databases (default in more recent bogofilter installations), upon encountering invalid input sequences, bogofilter or bogolexer could overrun a malloc()'d buffer, corrupting the heap, while converting character sets. Bogofilter would usually be processing untrusted data received from the network at that time.
This problem was aggravated by an unrelated bug that made bogofilter process binary attachments as though they were text, and attempt charset conversion on them. Given the MIME default character set, US-ASCII, all input octets in the range 0x80...0xff were considered invalid input sequences and could trigger the heap corruption.
A rxvt-unicode changelog reports:
SECURITY FIX: on systems using openpty, permissions were not correctly updated on the tty device and were left as world-readable and world-writable (likely in original rxvt, too), and were not restored properly. Affected are only systems where non-unix ptys were used (such as most BSDs). Found, patched and debugged by Ryan Beasley.
The Apache HTTP Server Project reports:
A flaw in mod_imap when using the Referer directive with image maps. In certain site configurations a remote attacker could perform a cross-site scripting attack if a victim can be forced to visit a malicious URL using certain web browsers.
Kurt Fitzner reports a buffer overflow vulnerability within nbd. This could potentially allow the execution of arbitrary code on the nbd server.
Max Vozeler reports:
If ALL the following conditions are true, administrators using scponly-4.1 or older may be at risk of a local privilege escalation exploit:
- the chrooted setuid scponlyc binary is installed
- regular non-scponly users have interactive shell access to the box
- a user executable dynamically linked setuid binary (such as ping) exists on the same file system mount as the user's home directory
- the operating system supports an LD_PRELOAD style mechanism to overload dynamic library loading
Pekka Pessi also reports:
If ANY the following conditions are true, administrators using scponly-4.1 or older may be at risk of a local privilege escalation exploit:
- scp compatibility is enabled
- rsync compatibility is enabled
The fetchmail team reports:
Fetchmail contains a bug that causes an application crash when fetchmail is configured for multidrop mode and the upstream mail server sends a message without headers. As fetchmail does not record this message as "previously fetched", it will crash with the same message if it is re-executed, so it cannot make progress. A malicious or broken-into upstream server could thus cause a denial of service in fetchmail clients.
Secunia Research reports:
Input passed to the "t_core_path" parameter in "bug_sponsorship_list_view_inc.php" isn't properly verified, before it used to include files. This can be exploited to include arbitrary files from external and local resources.
r0t reports:
Mantis contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to "target_field" parameter in "view_filters_page.php" isn't properly sanitised before being returned to the user. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Announce of Mnemo H3 (2.0.3) (final):
This [2.0.3] is a security release that fixes cross site scripting vulnerabilities in several of the notepad name and note data fields. None of the vulnerabilities can be exploited by unauthenticated users; however, we strongly recommend that all users of Mnemo 2.0.2 upgrade to 2.0.3 as soon as possible.
Announce of Nag H3 (2.0.4) (final):
This [2.0.4] is a security release that fixes cross site scripting vulnerabilities in several of the tasklist name and task data fields. None of the vulnerabilities can be exploited by unauthenticated users; however, we strongly recommend that all users of Nag 2.0.3 upgrade to 2.0.4 as soon as possible.
Announce of Turba H3 (2.0.5) (final):
This [2.0.5] is a security release that fixes cross site scripting vulnerabilities in several of the address book name and contact data fields. None of the vulnerabilities can be exploited by unauthenticated users; however, we strongly recommend that all users of Turba 2.0.4 upgrade to 2.0.5 as soon as possible.
Announce of Kronolith H3 (2.0.6) (final):
This [2.0.6] is a security release that fixes cross site scripting vulnerabilities in several of the calendar name and event data fields. None of the vulnerabilities can be exploited by unauthenticated users; however, we strongly recommend that all users of Kronolith 2.0.5 upgrade to 2.0.6 as soon as possible.
Announce of Horde H3 3.0.8 (final):
This [3.0.8] is a security release that fixes cross site scripting vulnerabilities in several of Horde's templates. None of the vulnerabilities can be exploited by unauthenticated users; however, we strongly recommend that all users of Horde 3.0.7 upgrade to 3.0.8 as soon as possible.
A Project cURL Security Advisory reports:
libcurl's URL parser function can overflow a malloced buffer in two ways, if given a too long URL.
1 - pass in a URL with no protocol (like "http://") prefix, using no slash and the string is 256 bytes or longer. This leads to a single zero byte overflow of the malloced buffer.
2 - pass in a URL with only a question mark as separator (no slash) between the host and the query part of the URL. This leads to a single zero byte overflow of the malloced buffer.
Both overflows can be made with the same input string, leading to two single zero byte overwrites.
The affected flaw cannot be triggered by a redirect, but the long URL must be passed in "directly" to libcurl. It makes this a "local" problem. Of course, lots of programs may still pass in user-provided URLs to libcurl without doing much syntax checking of their own, allowing a user to exploit this vulnerability.
Secunia reports:
Stefan Esser has reported a vulnerability in phpMyAdmin, which can be exploited by malicious people to conduct cross-site scripting attacks, disclose sensitive information, and compromise a vulnerable system.
The vulnerability is caused due to an error in the register_globals emulation layer in "grab_globals.php" where the "import_blacklist" variable is not properly protected from being overwritten. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site, and include arbitrary files from external and local resources.
A phpMyAdmin security advisory reports:
It was possible to conduct an XSS attack via the HTTP_HOST variable; also, some scripts in the libraries directory that handle header generation were vulnerable to XSS.
Secunia reports:
Simon Kilvington has reported a vulnerability in FFmpeg libavcodec, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially to compromise a user's system.
The vulnerability is caused due to a boundary error in the "avcodec_default_get_buffer()" function of "utils.c" in libavcodec. This can be exploited to cause a heap-based buffer overflow when a specially-crafted 1x1 ".png" file containing a palette is read.
Secunia reports:
A vulnerability has been reported in Trac, which can be exploited by malicious people to conduct SQL injection attacks.
Some unspecified input passed in the search module isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Secunia reports:
Some vulnerabilities have been reported in Drupal, which can be exploited by malicious people to bypass certain security restrictions, and conduct script insertion and HTTP response splitting attacks.
1) An input validation error in the filtering of HTML code can be exploited to inject arbitrary JavaScript code in submitted content, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed. Successful exploitation requires that the user has access to the full HTML input format. Ref: sa-2005-007
2) An input validation error in the attachment handling can be exploited to upload a malicious image with embedded HTML and script content, which will be executed in a user's browser session in context of an affected site when viewed directly with the Microsoft Internet Explorer browser. This can also be exploited to inject arbitrary HTTP headers, which will be included in the response sent to the user. Ref: sa-2005-008
3) The problem is that it is possible to bypass the "access user profile" permission. However, this cannot be exploited to modify data. Successful exploitation requires that the server runs PHP 5. Ref: sa-2005-009
Opera reports:
It is possible to make a form input that looks like an image link. If the form input has a "title" attribute, the status bar will show the "title". A "title" which looks like a URL can mislead the user, since the title can say http://nice.familiar.com/, while the form action can be something else.
Opera's tooltip says "Title:" before the title text, making a spoof URL less convincing. A user who has enabled the status bar and disabled tooltips can be affected by this. Neither of these settings are Opera's defaults.
This exploit is mostly of interest to users who disable JavaScript. If JavaScript is enabled, any link target or form action can be overridden by the script. The tooltip and the statusbar can only be trusted to show the true location if JavaScript is disabled.
Java code using LiveConnect methods to remove a property of a JavaScript object may in some cases use null pointers that can make Opera crash. This crash is not exploitable and such code is rare on the web.
An Opera Advisory reports:
Opera for UNIX uses a wrapper shell script to start up Opera. This shell script reads the input arguments, like the file names or URLs that Opera is to open. It also performs some environment checks, for example whether Java is available and if so, where it is located.
This wrapper script can also run commands embedded in the URL, so that a specially crafted URL can make arbitrary commands run on the recipient's machine. Users who have other programs set up to use Opera to open Web links are vulnerable to this flaw. For these users, clicking a Web link in for example OpenOffice.org or Evolution can run a command that was put into the link.
A Secunia Advisory reports:
peter MC tachatte has discovered a vulnerability in Mambo, which can be exploited by malicious people to manipulate certain information and compromise a vulnerable system.
The vulnerability is caused due to an error in the "register_globals" emulation layer in "globals.php" where certain arrays used by the system can be overwritten. This can be exploited to include arbitrary files from external and local resources via the "mosConfig_absolute_path" parameter.
Successful exploitation requires that "register_globals" is disabled.
Ghostscript is affected by an insecure temporary file creation vulnerability. This issue is likely due to a design error that causes the application to fail to verify the existence of a file before writing to it.
An attacker may leverage this issue to overwrite arbitrary files with the privileges of an unsuspecting user that activates the vulnerable application. Reportedly this issue is unlikely to facilitate privilege escalation.
Announce of Horde 3.0.7 (final):
This [3.0.7] is a security release that fixes cross site scripting vulnerabilities in two of Horde's MIME viewers. These holes could for example be exploited by an attacker sending specially crafted emails to Horde's webmail client IMP. The attack could be used to steal users' identity information, taking over users' sessions, or changing users' settings.
As a hotfix the css and tgz MIME drivers can be disabled by removing their entries from the $mime_drivers_map['horde']['registered'] list in horde/config/mime_drivers.php.
A phpMyAdmin security advisory reports:
Some scripts in phpMyAdmin are vulnerable to an HTTP Response Splitting attack.
Severity:
We consider these vulnerabilities to be serious. However, they can only be triggered on systems running with register_globals = on.
A Secunia Advisory reports:
Christopher Kunz has reported a vulnerability in phpSysInfo, which can be exploited by malicious people to manipulate certain information.
The vulnerability is caused due to an error in the "register_globals" emulation layer where certain arrays used by the system can be overwritten. This can be exploited to execute arbitrary HTML and script code in a user's browser session and include arbitrary files from local resources.
A Secunia Advisory reports:
A vulnerability has been reported in Macromedia Flash Player, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to missing validation of the frame type identifier that is read from a SWF file. This value is used as an index in Flash.ocx to reference an array of function pointers. This can be exploited via a specially crafted SWF file to cause the index to reference memory that is under the attacker's control, which causes Flash Player to use attacker supplied values as function pointers.
Successful exploitation allows execution of arbitrary code.
A Secunia Advisory reports:
Lostmon has reported some vulnerabilities in Flyspray, which can be exploited by malicious people to conduct cross-site scripting attacks.
Some input isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
A Secunia Advisory reports:
A vulnerability has been reported in SpamAssassin, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to the use of an inefficient regular expression in "/SpamAssassin/Message.pm" to parse email headers. This can cause perl to crash when it runs out of stack space and can be exploited via a malicious email that contains a large number of recipients.
Jens Steube reports that qpopper is vulnerable to a privilege escalation vulnerability. qpopper does not properly drop root privileges so that user supplied configuration and trace files can be processed with root privileges. This could allow a local attacker to create or modify arbitrary files.
qpopper is also affected by improper umask settings which could allow users to create group or world-writeable files, possibly allowing an attacker to overwrite arbitrary files.
Gregory Beaver reports:
A standard feature of the PEAR installer implemented in all versions of PEAR can lead to the execution of arbitrary PHP code upon running the "pear" command or loading the Web/Gtk frontend.
To be vulnerable, a user must explicitly install a publicly released malicious package using the PEAR installer, or explicitly install a package that depends on a malicious package.
James Yonan reports:
If the TCP server accept() call returns an error status, the resulting exception handler may attempt to indirect through a NULL pointer, causing a segfault. Affects all OpenVPN 2.0 versions.
James Yonan reports:
A format string vulnerability in the foreign_option function in options.c could potentially allow a malicious or compromised server to execute arbitrary code on the client. Only non-Windows clients are affected. The vulnerability only exists if (a) the client's TLS negotiation with the server succeeds, (b) the server is malicious or has been compromised such that it is configured to push a maliciously crafted options string to the client, and (c) the client indicates its willingness to accept pushed options from the server by having "pull" or "client" in its configuration file (Credit: Vade79).
A Secunia Advisory reports:
Some vulnerabilities have been reported in PHP, which can be exploited by malicious people to conduct cross-site scripting attacks, bypass certain security restrictions, and potentially compromise a vulnerable system.
A Secunia Advisory reports:
Some vulnerabilities have been reported in Skype, which can be exploited by malicious people to cause a DoS or to compromise a user's system.
A Secunia Advisory reports:
M.A.Young has reported a vulnerability in Squid, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in handling certain FTP server responses. This can be exploited to crash Squid by visiting a malicious FTP server via the proxy.
A Secunia Advisory reports:
Remco Verhoef has discovered a vulnerability in Basic Analysis and Security Engine (BASE), which can be exploited by malicious users to conduct SQL injection attacks.
The fetchmail team reports:
The fetchmailconf program before and excluding version 1.49 opened the run control file, wrote the configuration to it, and only then changed the mode to 0600 (rw-------). Writing the file, which usually contains passwords, before making it unreadable to other users, can expose sensitive password information.
Ulf Härnhammar reports:
When Lynx connects to an NNTP server to fetch information about the available articles in a newsgroup, it will call a function called HTrjis() with the information from certain article headers. The function adds missing ESC characters to certain data, to support Asian character sets. However, it does not check if it writes outside of the char array buf, and that causes a remote stack-based buffer overflow.
Ruby home page reports:
The Object Oriented Scripting Language Ruby supports safely executing an untrusted code with two mechanisms: safe level and taint flag on objects.
A vulnerability has been found that allows bypassing these mechanisms.
By using the vulnerability, arbitrary code can be executed beyond the restrictions specified in each safe level. Therefore, Ruby has to be updated on all systems that use safe level to execute untrusted code.
Ariel Berkman reports:
Unlike most of the supported image formats in xloadimage, the NIFF image format can store a title name of arbitrary length as part of the image file.
When xloadimage is processing a loaded image, it is creating a new Image object and then writing the processed image to it. At that point, it will also copy the title from the old image to the newly created image.
The 'zoom', 'reduce', and 'rotate' functions are using a fixed length buffer to construct the new title name when an image processing is done. Since the title name in a NIFF format is of varying length, and there are insufficient buffer size validations, the buffer can be overflowed.
Jennifer Steffens reports:
The Back Orifice preprocessor contains a stack-based buffer overflow. This vulnerability could be leveraged by an attacker to execute code remotely on a Snort sensor where the Back Orifice preprocessor is enabled. However, there are a number of factors that make remote code execution difficult to achieve across different builds of Snort on different platforms, even on the same platform with different compiler versions, and it is more likely that an attacker could use the vulnerability as a denial of service attack.
The Back Orifice preprocessor can be disabled by commenting out the line "preprocessor bo" in snort.conf. This can be done in any text editor using the following procedure:
- Locate the line "preprocessor bo"
- Comment out this line by preceding it with a hash (#). The new line will look like "#preprocessor bo"
- Save the file
- Restart snort
WebCalendar is proven vulnerable to a remote file inclusion vulnerability. The send_reminders.php does not properly verify the "includedir" parameter, giving remote attackers the possibility to include local and remote files. These files can be used by the attacker to gain access to the system.
Michael Dipper wrote:
A vulnerability has been discovered in gallery, which allows remote users unauthorized access to files on the webserver.
A remote user accessing gallery over the web may use specially crafted HTTP parameters to access arbitrary files located on the webserver. All files readable by the webserver process are subject to disclosure. The vulnerability is *not* restricted to the webserver's document root but extends to the whole server file space.
The vulnerability may be used by any anonymous user, there is no login to the application required.
Vulnerability:
Such applications are affected if they use the option SSL_OP_MSIE_SSLV2_RSA_PADDING. This option is implied by use of SSL_OP_ALL, which is intended to work around various bugs in third-party software that might prevent interoperability. The SSL_OP_MSIE_SSLV2_RSA_PADDING option disables a verification step in the SSL 2.0 server supposed to prevent active protocol-version rollback attacks. With this verification step disabled, an attacker acting as a "man in the middle" can force a client and a server to negotiate the SSL 2.0 protocol even if these parties both support SSL 3.0 or TLS 1.0. The SSL 2.0 protocol is known to have severe cryptographic weaknesses and is supported as a fallback only.
Applications using neither SSL_OP_MSIE_SSLV2_RSA_PADDING nor SSL_OP_ALL are not affected. Also, applications that disable use of SSL 2.0 are not affected.
A phpMyAdmin security announcement reports:
In libraries/grab_globals.lib.php, the $__redirect parameter was not correctly validated, opening the door to a local file inclusion attack.
We consider this vulnerability to be serious.
A Zope Hotfix Alert reports:
This hotfix resolves a security issue with docutils.
Affected are possibly all Zope instances that expose RestructuredText functionalies to untrusted users through the web.
Gentoo Linux Security Advisory reports:
Ulf Harnhammar discovered a format string bug in the routines handling CDDB server response contents.
An attacker could submit malicious information about an audio CD to a public CDDB server (or impersonate a public CDDB server). When the victim plays this CD on a multimedia frontend relying on xine-lib, it could end up executing arbitrary code.
FrSIRT reports:
A vulnerability has been identified in UW-IMAP, which could be exploited by remote attackers to execute arbitrary commands. This flaw is due to a stack overflow error in the "mail_valid_net_parse_work()" [src/c-client/mail.c] function that does not properly handle specially crafted mailbox names containing a quote (") character, which could be exploited by authenticated remote attackers to execute arbitrary commands with the privileges of the IMAP server.
Emanuel Haupt reports:
Someone who controls an FTP server that weex will log in to can set up malicious data in the account that weex will use, and that will cause a format string bug that will allow remote code execution. It will only happen when weex is first run or when its cache files are rebuilt with the -r option, though. The vulnerability was found by Ulf Harnhammar.
Shaun Colley reports:
When generating error and warning messages, picasm copies strings into fixed length buffers without bounds checking.
If an attacker could trick a user into assembling a source file with a malformed 'error' directive, arbitrary code could be executed with the privileges of the user. This could result in full system compromise.
The uim developers reports:
Masanari Yamamoto discovered that incorrect use of environment variables in uim. This bug causes privilege escalation if setuid/setgid applications was linked to libuim.
This bug appears in 'immodule for Qt' enabled Qt. (Normal Qt is also safe.) In some distribution, mlterm is also an setuid/setgid application.
A Debian Security Advisory reports:
Javier Fernández-Sanguino Peña discovered several insecure temporary file uses in cfengine, a tool for configuring and maintaining networked machines, that can be exploited by a symlink attack to overwrite arbitrary files owned by the user executing cfengine, which is probably root.
Gentoo Linux Security Advisory reports:
Clam AntiVirus is vulnerable to a buffer overflow in "libclamav/upx.c" when processing malformed UPX-packed executables. It can also be sent into an infinite loop in "libclamav/fsg.c" when processing specially-crafted FSG-packed executables.
By sending a specially-crafted file an attacker could execute arbitrary code with the permissions of the user running Clam AntiVirus, or cause a Denial of Service.
A Mozilla Foundation Security Advisory reports of multiple issues:
Heap overrun in XBM image processing
jackerror reports that an improperly terminated XBM image ending with space characters instead of the expected end tag can lead to a heap buffer overrun. This appears to be exploitable to install or run malicious code on the user's machine.
Thunderbird does not support the XBM format and is not affected by this flaw.
Crash on "zero-width non-joiner" sequence
Mats Palmgren discovered that a reported crash on Unicode sequences with "zero-width non-joiner" characters was due to stack corruption that may be exploitable.
XMLHttpRequest header spoofing
It was possible to add illegal and malformed headers to an XMLHttpRequest. This could have been used to exploit server or proxy flaws from the user's machine, or to fool a server or proxy into thinking a single request was a stream of separate requests. The severity of this vulnerability depends on the value of servers which might be vulnerable to HTTP request smuggling and similar attacks, or which share an IP address (virtual hosting) with the attacker's page.
For users connecting to the web through a proxy this flaw could be used to bypass the same-origin restriction on XMLHttpRequests by fooling the proxy into handling a single request as multiple pipe-lined requests directed at arbitrary hosts. This could be used, for example, to read files on intranet servers behind a firewall.
Object spoofing using XBL <implements>
moz_bug_r_a4 demonstrated a DOM object spoofing bug similar to MFSA 2005-55 using an XBL control that <implements> an internal interface. The severity depends on the version of Firefox: investigation so far indicates Firefox 1.0.x releases don't expose any vulnerable functionality to interfaces spoofed in this way, but that early Deer Park Alpha 1 versions did.
XBL was changed to no longer allow unprivileged controls from web content to implement XPCOM interfaces.
JavaScript integer overflow
Georgi Guninski reported an integer overflow in the JavaScript engine. We presume this could be exploited to run arbitrary code under favorable conditions.
Privilege escalation using about: scheme
heatsync and shutdown report two different ways to bypass the restriction on loading high privileged "chrome" pages from an unprivileged "about:" page. By itself this is harmless--once the "about" page's privilege is raised the original page no longer has access--but should this be combined with a same-origin violation this could lead to arbitrary code execution.
Chrome window spoofing
moz_bug_r_a4 demonstrates a way to get a blank "chrome" canvas by opening a window from a reference to a closed window. The resulting window is not privileged, but the normal browser UI is missing and can be used to construct a spoof page without any of the safety features of the browser chrome designed to alert users to phishing sites, such as the address bar and the status bar.
A Secunia Advisory reports:
Peter Zelezny has discovered a vulnerability in Firefox, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to the shell script used to launch Firefox parsing shell commands that are enclosed within backticks in the URL provided via the command line. This can e.g. be exploited to execute arbitrary shell commands by tricking a user into following a malicious link in an external application which uses Firefox as the default browser.
Marc Stern reports an off-by-one vulnerability in within mod_ssl. The vulnerability lies in mod_ssl's Certificate Revocation List (CRL). If Apache is configured to use a CRL this could allow an attacker to crash a child process causing a Denial of Service.
A Squirrelmail Advisory reports:
An extract($_POST) was done in options_identities.php which allowed for an attacker to set random variables in that file. This could lead to the reading (and possible writing) of other people's preferences, cross site scripting or writing files in webserver-writable locations.
Allocating large pixmaps by a client can trigger an integer overflow in the X server, potentially leading to execution of arbitrary code with elevated (root) privileges.
Imran Ghory reports a vulnerability within unzip. The vulnerability is caused by a race condition between extracting an archive and changing the permissions of the extracted files. This would give an attacker enough time to remove a file and hardlink it to another file owned by the user running unzip. When unzip changes the permissions of the file it could give the attacker access to files that normally would not have been accessible for others.
Tom Ferris reports:
A buffer overflow vulnerability exists within Firefox version 1.0.6 and all other prior versions which allows for an attacker to remotely execute arbitrary code on an affected host.
The problem seems to be when a hostname which has all dashes causes the NormalizeIDN call in nsStandardURL::BuildNormalizedSpec to return true, but is sets encHost to an empty string. Meaning, Firefox appends 0 to approxLen and then appends the long string of dashes to the buffer instead.
Note: It is possible to disable IDN support as a workaround to protect against this buffer overflow. How to do this is described on the What Firefox and Mozilla users should know about the IDN buffer overflow security issue web page.
Michael Krax reports a vulnerability within htdig. The vulnerability lies within an unsanitized config parameter, allowing a malicious attacker to execute arbitrary scripting code on the target's browser. This might allow the attacker to obtain the user's cookies which are associated with the site, including cookies used for authentication.
The squid patches page notes:
After certain slightly odd requests Squid crashes with a segmentation fault in sslConnectTimeout.
The squid patches page notes:
Squid crashes with the above assertion failure [assertion failed: store.c:523: "e->store_status == STORE_PENDING"] in certain conditions involving aborted requests.
Problem description
A DNSSEC-related validator function in BIND 9.3.0 contains an inappropriate internal consistency test. When this test is triggered, named(8) will exit.
Impact
On systems with DNSSEC enabled, a remote attacker may be able to inject a specially crafted packet that will cause the internal consistency test to trigger, and named(8) to terminate. As a result, the name server will no longer be available to service requests.
Workaround
DNSSEC is not enabled by default, and the "dnssec-enable" directive is not normally present. If DNSSEC has been enabled, disable it by changing the "dnssec-enable" directive to "dnssec-enable no;" in the named.conf(5) configuration file.
An ISC advisory reports a buffer overrun vulnerability within bind. The vulnerability could result in a Denial of Service. A workaround is available by disabling recursion and glue fetching.
Several filename-related stack overflow bugs allow a local attacker to elevate its privileges to the games group, since urban is installed setgid games.
Issue discovered and fixed by <shaun@rsc.cx>.
There is a command injection vulnerability in admin page of fswiki.
A SITIC Vulnerability Advisory reports:
Evolution suffers from several format string bugs when handling data from remote sources. These bugs lead to crashes or the execution of arbitrary assembly language code.
- The first format string bug occurs when viewing the full vCard data attached to an e-mail message.
- The second format string bug occurs when displaying contact data from remote LDAP servers.
- The third format string bug occurs when displaying task list data from remote servers.
- The fourth, and least serious, format string bug occurs when the user goes to the Calendars tab to save task list data that is vulnerable to problem 3 above. Other calendar entries that do not come from task lists are also affected.
Luke Howard reports:
If a pam_ldap client authenticates against an LDAP server that returns a passwordPolicyResponse control, but omits the optional "error" field of the PasswordPolicyResponseValue, then the LDAP authentication result will be ignored and the authentication step will always succeed.
The pcre library is vulnerable to a buffer overflow vulnerability due to insufficient validation of quantifier values. This could lead execution of arbitrary code with the permissions of the program using pcre by way of a specially crated regular expression.
Ulf Harnhammar has discovered a remotely exploitable buffer overflow in Elm e-mail client when parsing the Expires header of an e-mail message:
The attacker only needs to send the victim an e-mail message. When the victim with that message in his or her inbox starts Elm or simply views the inbox in an already started copy of Elm, the buffer overflow will happen immediately. The overflow is stack-based, and it gives full control over EIP, EBP and EBX. It is caused by a bad sscanf(3) call, using a format string containing "%s" to copy from a long char array to a shorter array.
James Yonan reports:
If two or more client machines try to connect to the server at the same time via TCP, using the same client certificate, and when --duplicate-cn is not enabled on the server, a race condition can crash the server with "Assertion failed at mtcp.c:411"
James Yonan reports:
A malicious [authenticated] client in "dev tap" ethernet bridging mode could theoretically flood the server with packets appearing to come from hundreds of thousands of different MAC addresses, causing the OpenVPN process to deplete system virtual memory as it expands its internal routing table.
James Yonan reports:
If the client sends a packet which fails to decrypt on the server, the OpenSSL error queue is not properly flushed, which can result in another unrelated client instance on the server seeing the error and responding to it, resulting in disconnection of the unrelated client.
James Yonan reports:
DoS attack against server when run with "verb 0" and without "tls-auth". If a client connection to the server fails certificate verification, the OpenSSL error queue is not properly flushed, which can result in another unrelated client instance on the server seeing the error and responding to it, resulting in disconnection of the unrelated client.
A tor advisory reports
Tor clients can completely loose anonymity, confidentiality, and data integrity if the first Tor server in their path is malicious. Specifically, if the Tor client chooses a malicious Tor server for her first hop in the circuit, that server can learn all the keys she negotiates for the rest of the circuit (or just spoof the whole circuit), and then read and/or modify all her traffic over that circuit.
A Adobe Security Advisory reports:
The identified vulnerability is a buffer overflow within a core application plug-in, which is part of Adobe Acrobat and Adobe Reader. If a malicious file were opened it could trigger a buffer overflow as the file is being loaded into Adobe Acrobat and Adobe Reader. A buffer overflow can cause the application to crash and increase the risk of malicious code execution.
A Hardened-PHP Project Security Advisory reports:
When the library parses XMLRPC requests/responses, it constructs a string of PHP code, that is later evaluated. This means any failure to properly handle the construction of this string can result in arbitrary execution of PHP code.
This new injection vulnerability is cause by not properly handling the situation, when certain XML tags are nested in the parsed document, that were never meant to be nested at all. This can be easily exploited in a way, that user-input is placed outside of string delimiters within the evaluation string, which obviously results in arbitrary code execution.
Note that several applications contains an embedded version on XML_RPC, therefor making them the vulnerable to the same code injection vulnerability.
An iDEFENSE Security Advisory reports:
Remote exploitation of an input validation vulnerability in AWStats allows remote attackers to execute arbitrary commands.
The problem specifically exists because of insufficient input filtering before passing user-supplied data to an
eval()
function. As part of the statistics reporting function, AWStats displays information about the most common referrer values that caused users to visit the website. The referrer data is used without proper sanitation in aneval()
statement, resulting in the execution of arbitrary perl code.Successful exploitation results in the execution of arbitrary commands with permissions of the web service. Exploitation will not occur until the stats page has been regenerated with the tainted referrer values from the http access log. Note that AWStats is only vulnerable in situations where at least one URLPlugin is enabled.
Wojtek Kaniewski reports:
Multiple vulnerabilities have been found in libgadu, a library for handling Gadu-Gadu instant messaging protocol. It is a part of ekg, a Gadu-Gadu client, but is widely used in other clients. Also some of the user contributed scripts were found to behave in an insecure manner.
- integer overflow in libgadu (CVE-2005-1852) that could be triggered by an incomming message and lead to application crash and/or remote code execution
- insecure file creation (CVE-2005-1850) and shell command injection (CVE-2005-1851) in other user contributed scripts (discovered by Marcin Owsiany and Wojtek Kaniewski)
- several signedness errors in libgadu that could be triggered by an incomming network data or an application passing invalid user input to the library
- memory alignment errors in libgadu that could be triggered by an incomming message and lead to bus errors on architectures like SPARC
- endianness errors in libgadu that could cause invalid behaviour of applications on big-endian architectures
The GAIM team reports:
A remote user could cause Gaim to crash on some systems by sending the Gaim user a file whose filename contains certain invalid characters. It is unknown what combination of systems are affected, but it is suspected that Windows users and systems with older versions of GTK+ are especially susceptible.
The GAIM team reports:
A remote AIM or ICQ user can cause a buffer overflow in Gaim by setting an away message containing many AIM substitution strings (such as %t or %n).
xpdf is vulnerable to a denial of service vulnerability which can cause xpdf to create an infinitely large file, thereby filling up the /tmp partition, when opening a specially crafted PDF file.
Note that several applications contains an embedded version of xpdf, therefor making them the vulnerable to the same DoS. In CUPS this vulnerability would cause the pdftops filter to crash.
Jose Antonio Coret reports that GForge contains multiple Cross Site Scripting vulnerabilities and an e-mail flood vulnerability:
The login form is also vulnerable to XSS (Cross Site Scripting) attacks. This may be used to launch phising attacks by sending HTML e-mails (i.e.: saying that you need to upgrade to the latest GForge version due to a security problem) and putting in the e-mail an HTML link that points to an specially crafted url that inserts an html form in the GForge login page and when the user press the login button, he/she send the credentials to the attackers website.
The 'forgot your password?' feature allows a remote user to load a certain URL to cause the service to send a validation e-mail to the specified user's e-mail address. There is no limit to the number of messages sent over a period of time, so a remote user can flood the target user's secondary e-mail address. E-Mail Flood, E-Mail bomber.
Postnuke Security Announcementss reports of the following vulnerabilities:
- missing input validation within /modules/Messages/readpmsg.php
- possible path disclosure within /user.php
- possible path disclosure within /modules/News/article.php
- possible remote code injection within /includes/pnMod.php
- possible cross-site-scripting in /index.php
- remote code injection via xml rpc library
A Secunia Advisory reports:
Some vulnerabilities have been reported in Mambo, where some have unknown impacts and others can be exploited by malicious people to conduct spoofing and SQL injection attacks.
- Input passed to the "user_rating" parameter when voting isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
- Some unspecified vulnerabilities in the "mosDBTable" class and the "DOMIT" library have an unknown impact.
- An unspecified error in the "administrator/index3.php" script can be exploited to spoof session IDs.
A programming error in the implementation of the AES-XCBC-MAC algorithm for authentication resulted in a constant key being used instead of the key specified by the system administrator.
If the AES-XCBC-MAC algorithm is used for authentication in the absence of any encryption, then an attacker may be able to forge packets which appear to originate from a different system and thereby succeed in establishing an IPsec session. If access to sensitive information or systems is controlled based on the identity of the source system, this may result in information disclosure or privilege escalation.
A fixed-size buffer is used in the decompression of data streams. Due to erronous analysis performed when zlib was written, this buffer, which was belived to be sufficiently large to handle any possible input stream, is in fact too small.
A carefully constructed compressed data stream can result in zlib overwriting some data structures. This may cause applications to halt, resulting in a denial of service; or it may result in an attacker gaining elevated privileges.
Due to insufficient parameter checking of the node type during device creation, any user can expose hidden device nodes on devfs mounted file systems within their jail. Device nodes will be created in the jail with their normal default access permissions.
Jailed processes can get access to restricted resources on the host system. For jailed processes running with superuser privileges this implies access to all devices on the system. This level of access can lead to information leakage and privilege escalation.
The ProFTPD release notes states:
sean <infamous42md at hotpop.com> found two format string vulnerabilities, one in mod_sql's SQLShowInfo directive, and one involving the 'ftpshut' utility. Both can be considered low risk, as they require active involvement on the part of the site administrator in order to be exploited.
These vulnerabilities could potentially lead to information disclosure, a denial-of-server situation, or execution of arbitrary code with the permissions of the user running ProFTPD.
When nbsmtp is executed in debug mode, server messages will be printed to stdout and logged via syslog. Syslog is used insecurely and user-supplied format characters are directly fed to the syslog function, which results in a format string vulnerability.
Under some circumstances, an SMTP server may be able to abuse this vulnerability in order to alter the nbsmtp process and execute malicious code.
Sylpheed is vulnerable to a buffer overflow when displaying emails with attachments that have MIME-encoded file names. This could be used by a remote attacker to crash sylpheed potentially allowing execution of arbitrary code with the permissions of the user running sylpheed.
A phpMyAdmin security announcement reports:
The convcharset parameter was not correctly validated, opening the door to a XSS attack.
Serge Mister and Robert Zuccherato reports that the OpenPGP protocol is vulnerable to a cryptographic attack when using symmetric encryption in an automated way.
David Shaw reports about the impact:
This attack, while very significant from a cryptographic point of view, is not generally effective in the real world. To be specific, unless you have your OpenPGP program set up as part of an automated system to accept encrypted messages, decrypt them, and then provide a response to the submitter, then this does not affect you at all.
Note that the fix
in GnuPG does note completely
eliminate the potential problem:
These patches disable a portion of the OpenPGP protocol that the attack is exploiting. This change should not be user visible. With the patch in place, this attack will not work using a public-key encrypted message. It will still work using a passphrase-encrypted message.
Georgi Guninski discovered a way to construct Vim modelines that execute arbitrary shell commands. The vulnerability can be exploited by including shell commands in modelines that call the glob() or expand() functions. An attacker could trick an user to read or edit a trojaned file with modelines enabled, after which the attacker is able to execute arbitrary commands with the privileges of the user.
Note: It is generally recommended that VIM
users use set nomodeline
in
~/.vimrc
to avoid the possibility of trojaned
text files.
A Gentoo Linux Security Advisory reports:
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a stack based buffer overflow in the libTIFF library when reading a TIFF image with a malformed BitsPerSample tag.
Successful exploitation would require the victim to open a specially crafted TIFF image, resulting in the execution of arbitrary code.
A Secunia Advisory reports:
Secunia Research has discovered a vulnerability in Opera, which can be exploited by malicious people to conduct cross-site scripting attacks and retrieve a user's files.
The vulnerability is caused due to Opera allowing a user to drag e.g. an image, which is actually a "javascript:" URI, resulting in cross-site scripting if dropped over another site. This may also be used to populate a file upload form, resulting in uploading of arbitrary files to a malicious web site.
Successful exploitation requires that the user is tricked into dragging and dropping e.g. an image or a link.
A Secunia Advisory reports:
Secunia Research has discovered a vulnerability in Opera, which can be exploited by malicious people to trick users into executing malicious files.
The vulnerability is caused due to an error in the handling of extended ASCII codes in the download dialog. This can be exploited to spoof the file extension in the file download dialog via a specially crafted "Content-Disposition" HTTP header.
Successful exploitation may result in users being tricked into executing a malicious file via the download dialog, but requires that the "Arial Unicode MS" font (ARIALUNI.TTF) has been installed on the system.
An Ethreal Security Advisories reports:
Our testing program has turned up several more security issues:
- The LDAP dissector could free static memory and crash.
- The AgentX dissector could crash.
- The 802.3 dissector could go into an infinite loop.
- The PER dissector could abort.
- The DHCP dissector could go into an infinite loop.
- The BER dissector could abort or loop infinitely.
- The MEGACO dissector could go into an infinite loop.

- The DHCP dissector could crash.
- The CAMEL dissector could crash.
- The PER dissector could crash.
- The RADIUS dissector could crash.
- The Telnet dissector could crash.
- The IS-IS LSP dissector could crash.
- The NCP dissector could crash.
iDEFENSE found the following issues:
- Several dissectors were susceptible to a format string overflow.
Impact:
It may be possible to make Ethereal crash, use up available memory, or run arbitrary code by injecting a purposefully malformed packet onto the wire or by convincing someone to read a malformed packet trace file.
A Watchfire whitepaper reports an vulnerability in the Apache webserver. The vulnerability can be exploited by malicious people causing cross site scripting, web cache poisoining, session hijacking and most importantly the ability to bypass web application firewall protection. Exploiting this vulnerability requires multiple carefully crafted HTTP requests, taking advantage of an caching server, proxy server, web application firewall etc. This only affects installations where Apache is used as HTTP proxy in combination with the following web servers:
An Secunia Advisory reports:
Neel Mehta and Alex Wheeler have reported some vulnerabilities in Clam AntiVirus, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
- Two integer overflow errors in "libclamav/tnef.c" when processing TNEF files can be exploited to cause a heap-based buffer overflow via a specially crafted TNEF file with a length value of -1 in the header.
- An integer overflow error in "libclamav/chmunpack.c" can be exploited to cause a heap-based buffer overflow via a specially crafted CHM file with a chunk entry that has a filename length of -1.
- A boundary error in "libclamav/fsg.c" when processing a FSG compressed file can cause a heap-based buffer overflow.
The ISC DHCP programs are vulnerable to several format string vulnerabilities which may allow a remote attacker to execute arbitrary code with the permissions of the DHCP programs, typically root for the DHCP server.
Multiple cross-site scripting (XSS) vulnerabilities in eGroupware before 1.0.0.007 allow remote attackers to inject arbitrary web script or HTML via the (1) ab_id, (2) page, (3) type, or (4) lang parameter to index.php or (5) category_id parameter.
Multiple SQL injection vulnerabilities in index.php in eGroupware before 1.0.0.007 allow remote attackers to execute arbitrary SQL commands via the (1) filter or (2) cats_app parameter.
In fetchmail 6.2.5.1, the remote code injection via POP3 UIDL was fixed, but a denial of service attack was introduced:
Two possible NULL-pointer dereferences allow a malicious POP3 server to crash fetchmail by respondig with UID lines containing only the article number but no UID (in violation of RFC-1939), or a message without Message-ID when no UIDL support is available.
Natanael Copa reports that dnrd is vulnerable to a remote buffer overflow and a remote stack overflow. These vulnerabilities can be triggered by sending invalid DNS packets to dnrd.
The buffer overflow could potentially be used to execute arbitrary code with the permissions of the dnrd daemon. Note that dnrd runs in an chroot environment and runs as non-root.
The stack overflow vulnerability can cause dnrd to crash.
The LDAP backend in PowerDNS has issues with escaping queries which could cause connection errors. This would make it possible for a malicious user to temporarily blank domains.
This is known to affect all releases prior to 2.9.18.
fetchmail's POP3/UIDL code does not truncate received UIDs properly. A malicious or compromised POP3 server can thus corrupt fetchmail's stack and inject code when fetchmail is using UIDL, either through configuration, or as a result of certain server capabilities. Note that fetchmail is run as root on some sites, so an attack might compromise the root account and thus the whole machine.
A KDE Security Advisory explains:
Kate / Kwrite create a file backup before saving a modified file. These backup files are created with default permissions, even if the original file had more strict permissions set.
Depending on the system security settings, backup files might be readable by other users. Kate / Kwrite are network transparent applications and therefore this vulnerability might not be restricted to local users.
The Mozilla Foundation reports of multiple security vulnerabilities in Firefox and Mozilla:
- MFSA 2005-56 Code execution through shared function objects
- MFSA 2005-55 XHTML node spoofing
- MFSA 2005-54 Javascript prompt origin spoofing

Kuba Zygmunt discovered a flaw in the input validation routines of Drupal's filter mechanism. An attacker could execute arbitrary PHP code on a target site when public comments or postings are allowed.
A Securityreason.com advisory reports that various cross site scripting vulnerabilities have been found in phpSysInfo. Input is not properly sanitised before it is returned to the user. A malicious person could exploit this to execute arbitrary HTML and script code in a users browser session. Also it is possible to view the full path of certain scripts by accessing them directly.
A Zataz advisory reports that MySQL contains a security flaw which could allow a malicious local user to inject arbitrary SQL commands during the initial database creation process.
The problem lies in the mysql_install_db script which creates temporary files based on the PID used by the script.
A Gentoo advisory reports:
Net-SNMP creates temporary files in an insecure manner, possibly allowing the execution of arbitrary code.
A malicious local attacker could exploit a race condition to change the content of the temporary files before they are executed by fixproc, possibly leading to the execution of arbitrary code. A local attacker could also create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When fixproc is executed, this would result in the file being overwritten.
phpBB is vulnerable to remote exploitation of an input validation vulnerability allows attackers to read the contents of arbitrary system files under the privileges of the webserver. This also allows remote attackers to unlink arbitrary system files under the privileges of the webserver.
A Zataz advisory reports that shtool contains a security flaw which could allow a malicious local user to create or overwrite the contents of arbitrary files. The attacker could fool a user into executing the arbitrary file possibly executing arbitrary code.
A Secunia Advisory reports:
A vulnerability has been reported in phpPgAdmin, which can be exploited by malicious people to disclose sensitive information.
Input passed to the "formLanguage" parameter in "index.php" isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources.
Successful exploitation requires that "magic_quotes_gpc" is disabled.
The pear-XML_RPC release notes reports that the following issues has been fixed:
Eliminate path disclosure vulnerabilities by suppressing error messages when eval()'ing.
Eliminate path disclosure vulnerability by catching bogus parameters submitted to
XML_RPC_Value::serializeval()
.
Eric Romang reports that ekg creates temporary files in an insecure manner. This can be exploited by an attacker using a symlink attack to overwrite arbitrary files and possibly execute arbitrary commands with the permissions of the user running ekg.
A Bugzilla Security Advisory reports:
Any user can change any flag on any bug, even if they don't have access to that bug, or even if they can't normally make bug changes. This also allows them to expose the summary of a bug.
Bugs are inserted into the database before they are marked as private, in Bugzilla code. Thus, MySQL replication can lag in between the time that the bug is inserted and when it is marked as private (usually less than a second). If replication lags at this point, the bug summary will be accessible to all users until replication catches up. Also, on a very slow machine, there may be a pause longer than a second that allows users to see the title of the newly-filed bug.
Insecure file permissions, network access control and DNS usage put systems that use Legato NetWorker at risk.
When the software is running, several files that contain sensitive information are created with insecure permissions. The information exposed include passwords and can therefore be used for privilege elevation.
An empty "servers" file, which should normally contain hostnames of authorized backup servers, may allow unauthorized backups to be made. Sensitive information can be extracted from these backups.
When reverse DNS fails for the Legato client IP a weak authorization scheme, containing a flaw that allows unauthorized access, is used. This may allow unauthorized access.
Secunia Research reports:
Secunia has discovered a security issue in Adobe Reader for Linux, which can be exploited by malicious, local users to gain knowledge of sensitive information.
The problem is caused due to temporary files being created with permissions based on a user's umask in the "/tmp" folder under certain circumstances when documents are opened.
Successful exploitation allows an unprivileged user to read arbitrary users' documents.
An iDEFENSE Security Advisory reports:
Remote exploitation of an input validation error in Clam AntiVirus ClamAV allows attackers to cause a denial of service condition.
The vulnerability specifically exists due to insufficient validation on cabinet file header data. The
ENSURE_BITS()
macro fails to check for zero length reads, allowing a carefully constructed cabinet file to cause an infinite loop.ClamAV is used in a number of mail gateway products. Successful exploitation requires an attacker to send a specially constructed CAB file through a mail gateway or personal anti-virus client utilizing the ClamAV scanning engine. The infinate loop will cause the ClamAV software to use all available processor resources, resulting in a denial of service or severe degradation to system performance. Remote exploitation can be achieved by sending a malicious file in an e-mail message or during an HTTP session.
An iDEFENSE Security Advisory reports:
Remote exploitation of an input validation error in Clam AntiVirus ClamAV allows attackers to cause a denial of service condition.
The vulnerability specifically exists due to improper behavior during exceptional conditions.
Successful exploitation allows attackers to exhaust file descriptors pool and memory. Anti-virus detection functionality will fail if there is no file descriptors available with which to open files. Remote exploitation can be achieved by sending a malicious file in an e-mail message or during an HTTP session.
An error in the handling of corrupt compressed data streams can result in a buffer being overflowed.
By carefully crafting a corrupt compressed data stream, an attacker can overwrite data structures in a zlib-using application. This may cause the application to halt, causing a denial of service; or it may result in the attacker gaining elevated privileges.
An Adobe Security Advisory reports:
A vulnerability within Adobe Reader has been identified. Under certain circumstances, remote exploitation of a buffer overflow in Adobe Reader could allow an attacker to execute arbitrary code.
If exploited, it could allow the execution of arbitrary code under the privileges of the local user. Remote exploitation is possible if the malicious PDF document is sent as an email attachment or if the PDF document is accessed via a web link.
A Net-SNMP release announcement reports:
A security vulnerability has been found in Net-SNMP releases that could allow a denial of service attack against Net-SNMP agent's which have opened a stream based protocol (EG, TCP but not UDP; it should be noted that Net-SNMP does not by default open a TCP port).
Stefan Esser reports:
Wrongly implemented user input filters lead to multiple SQL Injection vulnerabilities which can lead f.e. to disclosure of the admin password hash.
Wrongly implemented user input filters allows injection of user input into executed commandline.
Alberto Trivero posted his Remote Command Execution Exploit for Cacti <= 0.8.6d to Bugtraq on the 22th June. Having analysed his bug we come to the conclusion, that the malfunctioning input filters, which were already mentioned in the previous advisory are also responsible for this bug still being exploitable.
A HTTP headers bypass switch can also be used to completely bypass the authentification system of Cacti. As admin it is possible to execute shell commands with the permission of the webserver.
While looking at the source of Cacti a HTTP headers bypass switch was discovered, that also switches off a call to
session_start()
and the manual application ofaddslashes()
in case ofmagic_quotes_gpc=Off
.When register_globals is turned on* an attacker can use this switch to disables Cacti's use of PHP's session support and therefore supply the session variables on his own through f.e. the URL. Additionally using the switch renders several SQL statements vulnerable to SQL Injections attacks, when magic_quotes_gpc is turned off, which is the recommended setting.
Logged in as an admin it is possible to issue shell commands.
(*) register_globals is turned off by default since PHP 4.2 but is activated on most servers because of older scripts requiring it.
GulfTech Security Research reports:
There are a number of vulnerabilities in WordPress that may allow an attacker to ultimately run arbitrary code on the vulnerable system. These vulnerabilities include SQL Injection, Cross Site Scripting, and also issues that may aid an attacker in social engineering.
A Gentoo Linux Security Advisory reports:
Due to a lack of input validation, WordPress is vulnerable to SQL injection and XSS attacks.
An attacker could use the SQL injection vulnerabilities to gain information from the database. Furthermore the cross-site scripting issues give an attacker the ability to inject and execute malicious script code or to steal cookie-based authentication credentials, potentially compromising the victim's browser.
FrSIRT Advisory reports:
A vulnerability was identified in phpBB, which may be exploited by attackers to compromise a vulnerable web server. This flaw is due to an input validation error in the "viewtopic.php" script that does not properly filter the "highlight" parameter before calling the "preg_replace()" function, which may be exploited by remote attackers to execute arbitrary PHP commands with the privileges of the web server.
GulfTech Security Research Team reports:
PEAR XML_RPC is vulnerable to a very high risk php code injection vulnerability due to unsanatized data being passed into an eval() call.
The ipfw tables lookup code caches the result of the last query. The kernel may process multiple packets concurrently, performing several concurrent table lookups. Due to an insufficient locking, a cached result can become corrupted that could cause some addresses to be incorrectly matched against a lookup table.
When lookup tables are used with ipfw, packets may on very rare occasions incorrectly match a lookup table. This could result in a packet being treated contrary to the defined packet filtering ruleset. For example, a packet may be allowed to pass through when it should have been discarded.
The problem can only occur on Symmetric Multi-Processor (SMP) systems, or on Uni Processor (UP) systems with the PREEMPTION kernel option enabled (not the default).
a) Do not use lookup tables.
OR
b) Disable concurrent processing of packets in the network stack by setting the "debug.mpsafenet=0" tunable:
# echo "debug.mpsafenet=0" << /boot/loader.conf
Two problems have been discovered relating to the extraction of bzip2-compressed files. First, a carefully constructed invalid bzip2 archive can cause bzip2 to enter an infinite loop. Second, when creating a new file, bzip2 closes the file before setting its permissions.
The first problem can cause bzip2 to extract a bzip2 archive to an infinitely large file. If bzip2 is used in automated processing of untrusted files this could be exploited by an attacker to create an denial-of-service situation by exhausting disk space or by consuming all available cpu time.
The second problem can allow a local attacker to change the permissions of local files owned by the user executing bzip2 providing that they have write access to the directory in which the file is being extracted.
Do not uncompress bzip2 archives from untrusted sources and do not uncompress files in directories where untrusted users have write access.
Two problems have been discovered in the FreeBSD TCP stack.
First, when a TCP packets containing a timestamp is received, inadequate checking of sequence numbers is performed, allowing an attacker to artificially increase the internal "recent" timestamp for a connection.
Second, a TCP packet with the SYN flag set is accepted for established connections, allowing an attacker to overwrite certain TCP options.
Using either of the two problems an attacker with knowledge of the local and remote IP and port numbers associated with a connection can cause a denial of service situation by stalling the TCP connection. The stalled TCP connection my be closed after some time by the other host.
In some cases it may be possible to defend against these attacks by blocking the attack packets using a firewall. Packets used to effect either of these attacks would have spoofed source IP addresses.
An Ethreal Security Advisories reports:
An aggressive testing program as well as independent discovery has turned up a multitude of security issues
Please reference CVE/URL list for details
Roger Dingledine reports:
The Tor 0.1.0.10 release from a few days ago includes a fix for a bug that might allow an attacker to read arbitrary memory (maybe even keys) from an exit server's process space. We haven't heard any reports of exploits yet, but hey.
An iDEFENSE Security Advisory reports:
Remote exploitation of a heap-based buffer overflow vulnerability in the RealText file format parser within various versions of RealNetworks Inc.'s RealPlayer could allow attackers to execute arbitrary code.
Nobuhiro IMAI reports:
the default value modification on Module#public_instance_methods (from false to true) breaks s.add_handler(XMLRPC::iPIMethods("sample"), MyHandler.new) style security protection.
This problem could allow a remote attacker to execute arbitrary commands on XMLRPC server of libruby.
iDEFENSE security group disclosed potential SQL injection attacks from unchecked user input and two security holes regarding potential cross site scripting attacks
A Secunia Advisory reports:
Secunia Research has discovered a vulnerability in Opera, which can be exploited by malicious people to steal content or to perform actions on other web sites with the privileges of the user.
Normally, it should not be possible for the
XMLHttpRequest
object to access resources from outside the domain of which the object was opened. However, due to insufficient validation of server side redirects, it is possible to circumvent this restriction.
A Secunia Advisory reports:
Secunia Research has discovered a vulnerability in Opera, which can be exploited by malicious people to conduct cross-site scripting attacks and to read local files.
The vulnerability is caused due to Opera not properly restricting the privileges of "javascript:" URLs when opened in e.g. new windows or frames.
A Secunia Advisory reports:
Secunia Research has discovered a vulnerability in Opera, which can be exploited by malicious people to conduct cross-site scripting attacks against users.
The vulnerability is caused due to input not being sanitised, when Opera generates a temporary page for displaying a redirection when "Automatic redirection" is disabled (not default setting).
Todd C. Miller reports:
A race condition in Sudo's command pathname handling prior to Sudo version 1.6.8p9 that could allow a user with Sudo privileges to run arbitrary commands.
Exploitation of the bug requires that the user be allowed to run one or more commands via Sudo and be able to create symbolic links in the filesystem. Furthermore, a sudoers entry giving another user access to the ALL pseudo-command must follow the user's sudoers entry for the race to exist.
Stefan Esser reports:
Trac's wiki and ticket systems allows to add attachments to wiki entries and bug tracker tickets. These attachments are stored within directories that are determined by the id of the corresponding ticket or wiki entry.
Due to a missing validation of the id parameter it is possible for an attacker to supply arbitrary paths to the upload and attachment viewer scripts. This means that a potential attacker can retrieve any file accessible by the webserver user.
Additionally it is possible to upload arbitrary files (up to a configured file length) to any place the webserver has write access too.
For obvious reasons this can lead to the execution of arbitrary code if it possible to upload files to the document root or it's subdirectories. One example of a configuration would be f.e. running Trac and s9y/wordpress with writeable content directories on the same webserver.
Another potential usage of this exploit would be to abuse Trac powered webservers as storage for f.e. torrent files.
A Secunia security advisory reports:
Two vulnerabilities have been reported in Razor-agents, which can be exploited by malicious people to cause a DoS (Denial of Service).
- An unspecified error in the preprocessing of certain HTML messages can be exploited to crash the application.
- A bug in the discovery logic causes Razor-agents to go into an infinite loop and consume a large amount of memory when discovery fails.
Apache SpamAssassin Security Team reports:
Apache SpamAssassin 3.0.4 was recently released, and fixes a denial of service vulnerability in versions 3.0.1, 3.0.2, and 3.0.3. The vulnerability allows certain misformatted long message headers to cause spam checking to take a very long time.
While the exploit has yet to be seen in the wild, we are concerned that there may be attempts to abuse the vulnerability in the future. Therefore, we strongly recommend all users of these versions upgrade to Apache SpamAssassin 3.0.4 as soon as possible.
A SquirrelMail Security Advisory reports:
Several cross site scripting (XSS) vulnerabilities have been discovered in SquirrelMail versions 1.4.0 - 1.4.4.
The vulnerabilities are in two categories: the majority can be exploited through URL manipulation, and some by sending a specially crafted email to a victim. When done very carefully, this can cause the session of the user to be hijacked.
Sverre H. Huseby discovered a vulnerability in Adobe Acrobat and Adobe Reader. Under certain circumstances, using XML scripts it is possible to discover the existence of local files.
Two problems related to extraction of files exist in gzip:
The first problem is that gzip does not properly sanitize filenames containing "/" when uncompressing files using the -N command line option.
The second problem is that gzip does not set permissions on newly extracted files until after the file has been created and the file descriptor has been closed.
The first problem can allow an attacker to overwrite arbitrary local files when uncompressing a file using the -N command line option.
The second problem can allow a local attacker to change the permissions of arbitrary local files, on the same partition as the one the user is uncompressing a file on, by removing the file the user is uncompressing and replacing it with a hardlink before the uncompress operation is finished.
Do not use the -N command line option on untrusted files and do not uncompress files in directories where untrusted users have write access.
Several tcpdump protocol decoders contain programming errors which can cause them to go into infinite loops.
An attacker can inject specially crafted packets into the network which, when processed by tcpdump, could lead to a denial-of-service. After the attack, tcpdump would no longer capture traffic, and would potentially use all available processor time.
Jacopo Ottaviani reports that Gaim can be crashed by being offered files with names containing non-ASCII characters via the Yahoo! protocol.
The GAIM team reports:
Remote attackers can cause a denial of service (crash) via a malformed MSN message that leads to a memory allocation of a large size, possibly due to an integer signedness error.
A web server running Gallery can be exploited for arbitrary PHP code execution through the use of a maliciously crafted URL.
Gallery includes several cross-site scripting vulnerabilities that could allow malicious content to be injected.
A KDE Security Advisory explains:
Overview
KStars includes support for the Instrument Neutral Distributed Interface (INDI). The build system of this extra 3rd party software contained an installation hook to install fliccd (part of INDI) as SUID root application.
Erik Sjölund discovered that the code contains several vulnerabilities that allow stack based buffer overflows.
Impact
If the fliccd binary is installed as suid root, it enables root privilege escalation for local users, or, if the daemon is actually running (which it does not by default) and is running as root, remote root privilege escalation.
3APA3A reports:
If programmer fails to check socket number before using select() or fd_set macros, it's possible to overwrite memory behind fd_set structure. Very few select() based application actually check FD_SETSIZE value. [...]
Depending on vulnerable application it's possible to overwrite portions of memory. Impact is close to off-by-one overflows, code execution doesn't seems exploitable.
Matthias Andree reports:
A vulnerability was found in the fetchnews program (the NNTP client) that may under some circumstances cause a wait for input that never arrives, fetchnews "hangs". [...]
As only one fetchnews program can run at a time, subsequently started fetchnews and texpire programs will terminate. [...]
Upgrade your leafnode package to version 1.11.3.
An STG Security Advisory reports:
GForge CVS module made by Dragos Moinescu and another module made by Ronald Petty have a directory traversal vulnerability. [...] malicious attackers can read arbitrary directory lists.
The CRAM-MD5 authentication support of the University of Washington IMAP and POP3 servers contains a vulnerability that may allow an attacker to bypass authentication and impersonate arbitrary users. Only installations with CRAM-MD5 support configured are affected.
The Squid team reported several denial-of-service vulnerabilities related to the handling of DNS responses and NT Lan Manager messages. These may allow an attacker to crash the Squid cache.
Sebastian Krahmer discovered that the racoon ISAKMP daemon could be crashed with a maliciously crafted UDP packet. No authentication is required in order to perform the attack.
Tavis Ormandy discovered several integer overflows in xli's image size handling. A maliciously crafted image may be able to cause a heap buffer overflow and execute arbitrary code.
Tavis Ormandy discovered that xli and xloadimage attempt to
decompress images by piping them through gunzip
or similar decompression tools. Unfortunately, the
unsanitized file name is included as part of the command.
This is dangerous, as in some situations, such as mailcap
processing, an attacker may control the input file name. As a
result, an attacker may be able to cause arbitrary command
execution.
In 2001, zen-parse discovered a buffer overflow in xloadimage's FACES image loader. A maliciously crafted image could cause xloadimage to execute arbitrary code. A published exploit exists for this vulnerability.
In 2005, Rob Holland discovered that the same vulnerability was present in xli.
Stanislav Brabec discovered errors in yamt's path name handling that lead to buffer overflows and directory traversal issues. When processing a file with a maliciously crafted ID3 tag, yamt might overwrite arbitrary files or possibly execute arbitrary code.
The SuSE package ChangeLog contains:
- Several security fixes (#49337):
- directory traversal in rename
- directory traversal in sort
- buffer overflow in sort
- buffer overflow in rename
A Debian Security Advisory reports:
Erik Sjölund discovered that programs linked against xview are vulnerable to a number of buffer overflows in the XView library. When the overflow is triggered in a program which is installed setuid root a malicious user could perhaps execute arbitrary code as privileged user.
The X display locking program xtrlock
contains
an integer overflow bug. It is possible for an attacker with
physical access to the system to bypass the display lock.
Trevor Johnson reported that the Red Hat Linux RPMs used by linux_base contained multiple older vulnerabilities, such as a DNS resolver issue and critical bugs in X font handling and XPM image handling.
A SquirrelMail Security Advisory reports:
SquirrelMail 1.4.4 has been released to resolve a number of security issues disclosed below. It is strongly recommended that all running SquirrelMail prior to 1.4.4 upgrade to the latest release.
Remote File Inclusion
Manoel Zaninetti reported an issue in src/webmail.php which would allow a crafted URL to include a remote web page. This was assigned CAN-2005-0103 by the Common Vulnerabilities and Exposures.
Cross Site Scripting Issues
A possible cross site scripting issue exists in src/webmail.php that is only accessible when the PHP installation is running with register_globals set to On. This issue was uncovered internally by the SquirrelMail Development team. This isssue was assigned CAN-2005-0104 by the Common Vulnerabilities and Exposures.
A second issue which was resolved in the 1.4.4-rc1 release was uncovered and assigned CAN-2004-1036 by the Common Vulnerabilities and Exposures. This issue could allow a remote user to send a specially crafted header and cause execution of script (such as javascript) in the client browser.
Local File Inclusion
A possible local file inclusion issue was uncovered by one of our developers involving custom preference handlers. This issue is only active if the PHP installation is running with register_globals set to On.
Erik Sjölund discovered a vulnerability in Sympa. The
queue
application processes messages received via
aliases. It contains a buffer overflow in the usage of
sprintf
. In some configurations, it may allow an
attacker to execute arbitrary code as the sympa
user.
Florian Weimer wrote:
Mailman 2.1.5 uses weak auto-generated passwords for new subscribers. These passwords are assigned when members subscribe without specifying their own password (either by email or the web frontend). Knowledge of this password allows an attacker to gain access to the list archive even though she's not a member and the archive is restricted to members only. [...]
This means that only about 5 million different passwords are ever generated, a number that is in the range of brute force attacks -- you only have to guess one subscriber address (which is usually not that hard).
Barry Warsaw reports:
Today I am releasing Mailman 2.1.5, a bug fix release [...] This version also contains a fix for an exploit that could allow 3rd parties to retrieve member passwords. It is thus highly recommended that all existing sites upgrade to the latest version.
Oliver Karow discovered cross-site scripting issues in
the Apache Jakarta Tomcat manager. The developers refer to
the issues as minor
.
A Secunia security advisory reports:
A vulnerability has been reported in FreeStyle Wiki and FSWikiLite, which can be exploited by malicious people to conduct script insertion attacks.
Input passed in uploaded attachments is not properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious attachment is viewed.
A Gentoo Advisory reports:
The FreeRADIUS server is vulnerable to an SQL injection attack and a buffer overflow, possibly resulting in disclosure and modification of data and Denial of Service.
A Debian Advisory reports:
Jens Steube discovered that ppxp, yet another PPP program, does not release root privileges when opening potentially user supplied log files. This can be tricked into opening a root shell.
A RST/GHC Advisory reports that there is an format string vulnerability in oops. The vulnerability can be found in the MySQL/PgSQL authentication module. Succesful exploitation may allow execution of arbitrary code.
The developers of cdrdao report that there is a potential root exploit in the software. In order to be able to succesfully exploit this vulnerability cdrdao must be installed setuid root. When succesfully exploited a local user might get escalated privileges. By default this port is not installed setuid root.
The GAIM team reports:
Potential remote denial of service bug resulting from not checking a pointer for non-NULL before passing it to strncmp, which results in a crash. This can be triggered by a remote client sending an SLP message with an empty body.
The GAIM team reports that GAIM is vulnerable to a denial-of-service vulnerability which can cause GAIM to crash:
It is possible for a remote user to overflow a static buffer by sending an IM containing a very large URL (greater than 8192 bytes) to the Gaim user. This is not possible on all protocols, due to message length restrictions. Jabber are SILC are known to be vulnerable.
When running on processors supporting Hyper-Threading Technology, it is possible for a malicious thread to monitor the execution of another thread.
Information may be disclosed to local users, allowing in many cases for privilege escalation. For example, on a multi-user system, it may be possible to steal cryptographic keys used in applications such as OpenSSH or SSL-enabled web servers.
NOTE: Similar problems may exist in other simultaneous multithreading implementations, or even some systems in the absence of simultaneous multithreading. However, current research has only demonstrated this flaw in Hyper-Threading Technology, where shared memory caches are used.
Systems not using processors with Hyper-Threading Technology support are not affected by this issue. On systems which are affected, the security flaw can be eliminated by setting the "machdep.hlt_logical_cpus" tunable:
# echo "machdep.hlt_logical_cpus=1" >> /boot/loader.conf
The system must be rebooted in order for tunables to take effect.
Use of this workaround is not recommended on "dual-core" systems, as this workaround will also disable one of the processor cores.
When an upstream server aborts the transmission or stops sending data after the fetchnews program has requested an article header or body, fetchnews may crash, without querying further servers that are configured. This can prevent articles from being fetched.
A Mozilla Foundation Security Advisory reports:
Additional checks were added to make sure Javascript eval and Script objects are run with the privileges of the context that created them, not the potentially elevated privilege of the context calling them in order to protect against an additional variant of MFSA 2005-41.
The Mozilla Foundation Security Advisory MFSA 2005-41 reports:
moz_bug_r_a4 reported several exploits giving an attacker the ability to install malicious code or steal data, requiring only that the user do commonplace actions like click on a link or open the context menu.
A Mozilla Foundation Security Advisory reports:
Some security checks intended to prevent script injection were incorrect and could be bypassed by wrapping a javascript: url in the view-source: pseudo-protocol. Michael Krax demonstrated that a variant of his favicon exploit could still execute arbitrary code, and the same technique could also be used to perform cross-site scripting.
Georgi Guninski demonstrated the same flaw wrapping javascript: urls with the jar: pseudo-protocol.
L. David Baron discovered a nested variant that defeated checks in the script security manager.
Workaround: Disable Javascript
A Mozilla Foundation Security Advisory reports:
Two vulnerabilities have been discovered in Firefox, which can be exploited by malicious people to conduct cross-site scripting attacks and compromise a user's system.
- The problem is that "IFRAME" JavaScript URLs are not properly protected from being executed in context of another URL in the history list. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an arbitrary site.
- Input passed to the "IconURL" parameter in "InstallTrigger.install()" is not properly verified before being used. This can be exploited to execute arbitrary JavaScript code with escalated privileges via a specially crafted JavaScript URL.
Successful exploitation requires that the site is allowed to install software (default sites are "update.mozilla.org" and "addons.mozilla.org").
A combination of vulnerability 1 and 2 can be exploited to execute arbitrary code.
The eqn2graph and pic2graph scripts in groff 1.18.1 allow local users to overwrite arbitrary files via a symlink attack on temporary files.
The groffer script in the groff package 1.18 and later versions allows local users to overwrite files via a symlink attack on temporary files.
An Ubuntu Advisory reports:
Joey Hess discovered that "unshar" created temporary files in an insecure manner. This could allow a symbolic link attack to create or overwrite arbitrary files with the privileges of the user invoking the program.
An rsnapshot Advisory reports:
The copy_symlink() subroutine in rsnapshot incorrectly changes file ownership on the files pointed to by symlinks, not on the symlinks themselves. This would allow, under certain circumstances, an arbitrary user to take ownership of a file on the main filesystem.
GHC team reports about coppermine
The lack of sanitizing of user defined variables may result in undesirable consequences such as IP spoofing or XSS attack.
Generally users of Coppermine Gallery can post comments. Remote address & x-forwarded-for variables are logged for admin's eyes. X-Forwarded-for variable does not pass throu any filtration before logging into database. User can define/redefine this variable.
Damian Put reports about ImageMagick:
Remote exploitation of a heap overflow vulnerability could allow execution of arbitrary code or course denial of service.
A heap overflow exists in ReadPNMImage() function, that is used to decode a PNM image files.
A xine security announcement reports:
By a user receiving data from a malicious network streaming server, an attacker can overrun a heap buffer, which can, on some systems, lead to or help in executing attacker-chosen malicious code with the permissions of the user running a xine-lib based media application.
Both the MMS and Real RTSP streaming client code made some too-strong assumptions on the transferred data. Several critical bounds checks were missing, resulting in the possibility of heap overflows, should the remote server not adhere to these assumptions. In the MMS case, a remote server could present content with too many individual streams; in the RTSP case, a remote server's reply could have too many lines.
An attacker can set up a server delivering malicious data to the users. This can be used to overflow a heap buffer, which can, with certain implementations of heap management, lead to attacker chosen data written to the stack. This can cause attacker-chosen code being executed with the permissions of the user running the application. By tricking users to retrieve a stream, which can be as easy as providing a link on a website, this vulnerability can be exploited remotely.
The GAIM team reports that GAIM is vulnerable to a denial-of-service vulnerability which can cause GAIM to freeze:
Certain malformed SNAC packets sent by other AIM or ICQ users can trigger an infinite loop in Gaim when parsing the SNAC. The remote user would need a custom client, able to generate malformed SNACs.
The GAIM team reports:
Receiving malformed HTML can result in an invalid memory access causing Gaim to crash.
A KDE Security Advisory reports:
Kommander executes without user confirmation data files from possibly untrusted locations. As they contain scripts, the user might accidentally run arbitrary code.
Impact: Remotly supplied kommander files from untrusted sources are executed without confirmation.
A Debian advisory reports:
James Ranson discovered that an attacker can modify the referrer setting with a carefully crafted URL by accidently overwriting a global variable.
Tavis Ormandy from the Gentoo Security Team discovered several heap corruptions due to inconsistent use of an internal function that can crash the daemon or possibly lead to the execution of arbitrary code.
A KDE Security Advisory reports:
kimgio contains a PCX image file format reader that does not properly perform input validation. A source code audit performed by the KDE security team discovered several vulnerabilities in the PCX and other image file format readers, some of them exploitable to execute arbitrary code.
Impact: Remotely supplied, specially crafted image files can be used to execute arbitrary code.
Gld has been found vulnerable to multiple buffer overflows as well as multiple format string vulnerabilities.
An attacker could exploit this vulnerability to execute arbitrary code with the permissions of the user running Gld, the default user being root.
The FreeBSD port defaults to running gld as the root user. The risk of exploitation can be minimized by making gld listen on the loopback address only, or configure it to only accept connections from trusted smtp servers.
A Debian Security Advisory reports:
Ulf Härnhammar from the Debian Security Audit Project discovered a buffer overflow in axel, a light download accelerator. When reading remote input the program did not check if a part of the input can overflow a buffer and maybe trigger the execution of arbitrary code.
A Mozilla Foundation Security Advisory reports:
When a webpage requires a plugin that is not installed the user can click to launch the Plugin Finder Service (PFS) to find an appropriate plugin. If the service does not have an appropriate plugin the EMBED tag is checked for a PLUGINSPAGE attribute, and if one is found the PFS dialog will contain a "manual install" button that will load the PLUGINSPAGE url.
Omar Khan reported that if the PLUGINSPAGE attribute contains a javascript: url then pressing the button could launch arbitrary code capable of stealing local data or installing malicious code.
Doron Rosenberg reported a variant that injects script by appending it to a malformed URL of any protocol.
Pluf has discovered a vulnerability in Sun Java JDK/SDK, which potentially can be exploited by malicious people to compromise a user's system.
The jar tool does not check properly if the files to be extracted have the string "../" on its names, so it's possible for an attacker to create a malicious jar file in order to overwrite arbitrary files within the filesystem.
A Mozilla Foundation Security Advisory reports:
moz_bug_r_a4 reported several exploits giving an attacker the ability to install malicious code or steal data, requiring only that the user do commonplace actions like click on a link or open the context menu. The common cause in each case was privileged UI code ("chrome") being overly trusting of DOM nodes from the content window. Scripts in the web page can override properties and methods of DOM nodes and shadow the native values, unless steps are taken to get the true underlying values.
We found that most extensions also interacted with content DOM in a natural, but unsafe, manner. Changes were made so that chrome code using this natural DOM coding style will now automatically use the native DOM value if it exists without having to use cumbersome wrapper objects.
Most of the specific exploits involved tricking the privileged code into calling eval() on an attacker-supplied script string, or the equivalent using the Script() object. Checks were added in the security manager to make sure eval and Script objects are run with the privileges of the context that created them, not the potentially elevated privileges of the context calling them.
Workaround: Disable Javascript
A Mozilla Foundation Security Advisory reports:
Firefox and the Mozilla Suite support custom "favicons" through the <LINK rel="icon"> tag. If a link tag is added to the page programmatically and a javascript: url is used, then script will run with elevated privileges and could run or install malicious software.
Workaround: Disable Javascript
A Mozilla Foundation Security Advisory reports:
A bug in javascript's regular expression string replacement when using an anonymous function as the replacement argument allows a malicious script to capture blocks of memory allocated to the browser. A web site could capture data and transmit it to a server without user interaction or knowledge.
Workaround: Disable Javascript
A Mozilla Foundation Security Advisory reports:
Sites can use the _search target to open links in the Firefox sidebar. Two missing security checks allow malicious scripts to first open a privileged page (such as about:config) and then inject script using a javascript: url. This could be used to install malicious code or steal data without user interaction.
Workaround: Disable Javascript
AD-LAB reports that a heap-based buffer overflow vulnerability exists in OpenOffice's handling of DOC documents. When reading a DOC document 16 bit from a 32 bit integer is used for memory allocation, but the full 32 bit is used for further processing of the document. This can allow an attacker to crash OpenOffice, or potentially execute arbitrary code as the user running OpenOffice, by tricking an user into opening a specially crafted DOC document.
Simon L. Nielsen discovered that portupgrade handles temporary files in an insecure manner. This could allow an unprivileged local attacker to execute arbitrary commands or overwrite arbitrary files with the permissions of the user running portupgrade, typically root, by way of a symlink attack.
The following issues exist where the temporary files are created, by default in the world writeable directory /var/tmp, with the permissions of the user running portupgrade:
toucha temporary file with a constant filename (pkgdb.fixme) allowing an attacker to create arbitrary zero-byte files via a symlink attack.
A workaround for these issues is to set the
PKG_TMPDIR
environment variable to a directory
only write-able by the user running portupgrade.
The GAIM team reports:
A remote jabber user can cause Gaim to crash by sending a specific file transfer request.
The GAIM team reports:
The IRC protocol plugin in Gaim 1.2.0, and possibly earlier versions, allows (1) remote attackers to inject arbitrary Gaim markup via irc_msg_kick, irc_msg_mode, irc_msg_part, irc_msg_quit, (2) remote attackers to inject arbitrary Pango markup and pop up empty dialog boxes via irc_msg_invite, or (3) malicious IRC servers to cause a denial of service (application crash) by injecting certain Pango markup into irc_msg_badmode, irc_msg_banned, irc_msg_unknown, irc_msg_nochan functions.
The GAIM team reports:
The gaim_markup_strip_html function in Gaim 1.2.0, and possibly earlier versions, allows remote attackers to cause a denial of service (application crash) via a string that contains malformed HTML, which causes an out-of-bounds read.
A SUSE Security advisory reports:
A bug in the readfile() function of php4 could be used to to crash the httpd running the php4 code when accessing files with a multiple of the architectures page size leading to a denial of service.
The squid patches page notes:
An inconsistent state is entered on a failed PUT/POST request making a high risk for segmentation faults or other strange errors
Secunia Advisory: SA14730
A vulnerability has been reported in Horde, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed when setting the parent frame's page title via JavaScript is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerability has been reported in version 3.0.4-RC2. Prior versions may also be affected.
An iDEFENSE Security Advisory reports:
Remote exploitation of an input validation vulnerability in version 2.6.2 of WU-FPTD could allow for a denial of service of the system by resource exhaustion.
The vulnerability specifically exists in the
wu_fnmatch()
function in wu_fnmatch.c. When a pattern containing a '*' character is supplied as input, the function calls itself recursively on a smaller substring. By supplying a string which contains a large number of '*' characters, the system will take a long time to return the results, during which time it will be using a large amount of CPU time.
A Gentoo Linux Security Advisory reports:
Tavis Ormandy of the Gentoo Linux Security Audit Team identified a flaw in the Hashcash utility that an attacker could expose by specifying a malformed reply address.
Successful exploitation would permit an attacker to disrupt Hashcash users, and potentially execute arbitrary code.
The clamav daemon is vulnerable to a DoS vulnerability due to insufficient handling of malformed zip files which can crash the clamav daemon.
Due to insecure temporary file creation in the Wine Windows emulator, it is possible for any user to read potentially sensitive information from temporary registry files.
When a Win32 application is launched by wine, wine makes a dump of the Windows registry in /tmp with name regxxxxyyyy.tmp , where xxxxxx is the pid in hexadecimal value of the current wine process and yyyy is an integer value usually equal to zero.
regxxxxyyyy.tmp is created with 0644 (-rw-r--r--) permissions. This could represent a security problem in a multi-user environment. Indeed, any local user could access to windows regstry's dump and get sensitive information, like passwords and other private data.
A Mozilla Foundation Security Advisory states:
If a user bookmarked a malicious page as a Firefox sidebar panel that page could execute arbitrary programs by opening a privileged page and injecting javascript into it.
A Mozilla Foundation Security Advisory states:
An (sic) GIF processing error when parsing the obsolete Netscape extension 2 can lead to an exploitable heap overrun, allowing an attacker to run arbitrary code on the user's machine.
The Sylpheed web site states:
A buffer overflow which occurred when replying to a message with certain headers which contain non-ascii characters was fixed.
A Gentoo Linux Security Advisory reports:
Tavis Ormandy of the Gentoo Linux Security Audit Team identified a flaw in the handling of image filenames by xv.
Successful exploitation would require a victim to process a specially crafted image with a malformed filename, potentially resulting in the execution of arbitrary code.
A KDE Security Advisory reports:
Sebastian Krahmer of the SUSE LINUX Security Team reported a local denial of service vulnerability in KDE's Desktop Communication Protocol (DCOP) daemon better known as dcopserver.
A local user can lock up the dcopserver of arbitrary other users on the same machine. This can cause a significant reduction in desktop functionality for the affected users including, but not limited to, the inability to browse the internet and the inability to start new applications.
The phpMyAdmin team reports:
Escaping of the "_" character was not properly done, giving a wildcard privilege when editing db-specific privileges with phpMyAdmin.
An Ethreal Security Advisories reports:
Issues have been discovered in the following protocol dissectors:
- Matevz Pustisek discovered a buffer overflow in the Etheric dissector. CVE: CAN-2005-0704
- The GPRS-LLC dissector could crash if the "ignore cipher bit" option was enabled. CVE: CAN-2005-0705
- Diego Giago discovered a buffer overflow in the 3GPP2 A11 dissector. This flaw was later reported by Leon Juranic. CVE: CAN-2005-0699
- Leon Juranic discovered a buffer overflow in the IAPP dissector. CVE: CAN-2005-0739
- A bug in the JXTA dissector could make Ethereal crash.
- A bug in the sFlow dissector could make Ethereal crash.
Joseph VanAndel reports that grip is vulnerability to a buffer overflow vulnerability when receiving more than 16 CDDB responses. This could lead to a crash in grip and potentially execution arbitrary code.
A workaround is to disable CDDB lookups.
SecurityFocus reports:
MySQL is reported prone to an insecure temporary file creation vulnerability.
Reports indicate that an attacker that has 'CREATE TEMPORARY TABLE' privileges on an affected installation may leverage this vulnerability to corrupt files with the privileges of the MySQL process.
MySQL is reported prone to an input validation vulnerability that can be exploited by remote users that have INSERT and DELETE privileges on the 'mysql' administrative database.
Reports indicate that this issue may be leveraged to load an execute a malicious library in the context of the MySQL process.
Finally, MySQL is reported prone to a remote arbitrary code execution vulnerability. It is reported that the vulnerability may be triggered by employing the 'CREATE FUNCTION' statement to manipulate functions in order to control sensitive data structures.
This issue may be exploited to execute arbitrary code in the context of the database process.
A rxvt-unicode changelog reports:
Fix a bug that allowed to overflow a buffer via a long escape sequence, which is probably exploitable (fix by Rob Holland / Yoann Vandoorselaere / Gentoo Audit Team).
A phpMyAdmin security announcement reports:
By calling some scripts that are part of phpMyAdmin in an unexpected way (especially scripts in the libraries subdirectory), it is possible to trigger phpMyAdmin to display a PHP error message which contains the full path of the directory where phpMyAdmin is installed.
Mitigation factor: This path disclosure is possible on servers where the recommended setting of the PHP configuration directive
display_errors
is set to on, which is against the recommendations given in the PHP manual.
A phpMyAdmin security announcement reports:
We received two bug reports by Maksymilian Arciemowicz about those vulnerabilities and we wish to thank him for his work. The vulnerabilities apply to those points:
- css/phpmyadmin.css.php was vulnerable against
$cfg
andGLOBALS
variable injections. This way, a possible attacker could manipulate any configuration parameter. Using phpMyAdmin's theming mechanism, he was able to include arbitrary files. This is especially dangerous if php is not running in safe mode.- A possible attacker could manipulate phpMyAdmin's localized strings via the URL and inject harmful JavaScript code this way, which could be used for XSS attacks.
Sylvain Defresne reports that libexif is vulnerable to a buffer overflow vulnerability due to insufficient input checking. This could lead crash of applications using libexif.
Neo Security Team reports:
If we specify a variable in the html code (any type: hidden, text, radio, check, etc) with the name allowhtml, allowbbcode or allowsmilies, is going to be on the html, bbcode and smilies in our signature.
This is a low risk vulnerability that allows users to bypass forum-wide configuration.
Two separate SQL injection vulnerabilities have been identified in the PostNuke PHP content management system. An attacker can use this vulnerability to potentially insert executable PHP code into the content management system (to view all files within the PHP scope, for instance). Various other SQL injection vulnerabilities exist, which give attackers the ability to run SQL queries on any tables within the database.
A cross-site scripting vulnerability is present in the PostNuke PHP content management system. By passing data injected through exploitable errors in input validation, an attacker can insert code which will run on the machine of anybody viewing the page. It is feasible that this attack could be used to retrieve session information from cookies, thereby allowing the attacker to gain administrative access to the CMS.
Two exploits have been identified in the Linux RealPlayer client. RealNetworks states:
RealNetworks, Inc. has addressed recently discovered security vulnerabilities that offered the potential for an attacker to run arbitrary or malicious code on a customer's machine. RealNetworks has received no reports of machines compromised as a result of the now-remedied vulnerabilities. RealNetworks takes all security vulnerabilities very seriously.
The specific exploits were:
- Exploit 1: To fashion a malicious WAV file to cause a buffer overflow which could have allowed an attacker to execute arbitrary code on a customer's machine.
- Exploit 2: To fashion a malicious SMIL file to cause a buffer overflow which could have allowed an attacker to execute arbitrary code on a customer's machine.
Tavis Ormandy reports:
magemagick-6.2.0-3 fixes an potential issue handling malformed filenames, the flaw may affect webapps or scripts that use the imagemagick utilities for image processing, or applications linked with libMagick.
This vulnerability could crash ImageMagick or potentially lead to the execution of arbitrary code with the permissions of the user running ImageMagick.
The uim developers reports:
Takumi ASAKI discovered that uim always trusts environment variables. But this is not correct behavior, sometimes environment variables shouldn't be trusted. This bug causes privilege escalation when libuim is linked against setuid/setgid application. Since GTK+ prohibits setuid/setgid applications, the bug appears only in 'immodule for Qt' enabled Qt. (Normal Qt is also safe.)
The lighttpd website reports:
In lighttpd 1.3.7 and below it is possible to fetch the source files which should be handled by CGI or FastCGI applications.
The vulnerability is in the handling of urlencoded trailing NUL bytes. Installations that do not use CGI or FastCGI are not affected.
The phpbb developer group reports:
phpBB Group announces the release of phpBB 2.0.13, the "Beware of the furries" edition. This release addresses two recent security exploits, one of them critical. They were reported a few days after .12 was released and no one is more annoyed than us, having to release a new version ini such a short period of time. Fortunately both fixes are easy and in each case just one line needs to be edited.
Two iDEFENSE Security Advisories reports:
An exploitable stack-based buffer overflow condition exists when using NT Lan Manager (NTLM) authentication. The problem specifically exists within
Curl_input_ntlm()
defined in lib/http_ntlm.c.Successful exploitation allows remote attackers to execute arbitrary code under the privileges of the target user. Exploitation requires that an attacker either coerce or force a target to connect to a malicious server using NTLM authentication.
An exploitable stack-based buffer overflow condition exists when using Kerberos authentication. The problem specifically exists within the functions
Curl_krb_kauth()
andkrb4_auth()
defined in lib/krb4.c.Successful exploitation allows remote attackers to execute arbitrary code under the privileges of the target user. Exploitation requires that an attacker either coerce or force a target to connect to a malicious server using Kerberos authentication.
The Cyrus IMAP Server ChangeLog states:
- Fix possible single byte overflow in mailbox handling code.
- Fix possible single byte overflows in the imapd annotate extension.
- Fix stack buffer overflows in fetchnews (exploitable by peer news server), backend (exploitable by admin), and in imapd (exploitable by users though only on platforms where a filename may be larger than a mailbox name).
The 2.1.X series are reportedly only affected by the second issue.
These issues may lead to execution of arbitrary code with the permissions of the user running the Cyrus IMAP Server.
Debian Security Advisory reports:
jaguar@felinemenace.org discovered a format string vulnerability in sup, a set of programs to synchronize collections of files across a number of machines, whereby a remote attacker could potentially cause arbitrary code to be executed with the privileges of the supfilesrv process (this process does not run automatically by default).
A Mozilla Foundation Security Advisory reports:
A predictable name is used for the plugin temporary directory. A malicious local user could symlink this to the victim's home directory and wait for the victim to run Firefox. When Firefox shuts down the victim's directory would be erased.
A Mozilla Foundation Security Advisory reports:
Plugins (such as flash) can be used to load privileged content into a frame. Once loaded various spoofs can be applied to get the user to interact with the privileged content. Michael Krax's "Fireflashing" example demonstrates that an attacker can open about:config in a frame, hide it with an opacity setting, and if the attacker can get the victim to click at a particular spot (design some kind of simple game) you could toggle boolean preferences, some of which would make further attacks easier.
The "firescrolling" example demonstrates arbitrary code execution (in this case downloading a file) by convincing the user to scroll twice.
Workaround: Disable JavaScript.
The version 0.06_1 and prior have a format string vulnerability which can be triggered by using a carefully-crafted BDF font file.
psoTFX reports:
phpBB Group are pleased to announce the release of phpBB 2.0.12 the "Horray for Furrywood" release. This release addresses a number of bugs and a couple of potential exploits. [...] one of the potential exploits addressed in this release could be serious in certain situations and thus we urge all users, as always, to upgrade to this release as soon as possible. Mostly this release is concerned with eliminating disclosures of information which while useful in debug situations may allow third parties to gain information which could be used to do harm via unknown or unfixed exploits in this or other applications.
The ChangeLog for phpBB 2.0.12 states:
- Prevented full path display on critical messages
- Fixed full path disclosure in username handling caused by a PHP 4.3.10 bug - AnthraX101
- Added exclude list to unsetting globals (if register_globals is on) - SpoofedExistence
- Fixed arbitrary file disclosure vulnerability in avatar handling functions - AnthraX101
- Fixed arbitrary file unlink vulnerability in avatar handling functions - AnthraX101
- Fixed path disclosure bug in search.php caused by a PHP 4.3.10 bug (related to AnthraX101's discovery)
- Fixed path disclosure bug in viewtopic.php caused by a PHP 4.3.10 bug - matrix_killer
Ulf Härnhammar reports:
Secunia reports:
The vulnerabilities have been confirmed in version 1.2b. One of the buffer overflow vulnerabilities have also been reported in version 2.04, 2.2 and 2.5. Other versions may also be affected.
Successful exploitation may allow execution of arbitrary code.
Simon Tatham reports:
This version fixes a security hole in previous versions of PuTTY, which can allow a malicious SFTP server to attack your client. If you use either PSCP or PSFTP, you should upgrade. Users of the main PuTTY program are not affected. (However, note that the server must have passed host key verification before this attack can be launched, so a man-in-the-middle shouldn't be able to attack you if you're careful.)
Davide Madrisan reports:
The `dcopidlng' script in the KDE library package (kdelibs-3.3.2/dcop/dcopidlng/dcopidlng) creates temporary files in a unsecure manner.
Note: dcopidlng is only used at build time, so only users installing KDE are vulnerable, not users already running KDE.
A Debian Security Advisory reports:
Ulf Härnhammer from the Debian Security Audit Project discovered a format string vulnerability in bidwatcher, a tool for watching and bidding on eBay auctions. This problem can be triggered remotely by a web server of eBay, or someone pretending to be eBay, sending certain data back.
A Debian Security Advisory reports:
Albert Puigsech Galicia discovered a directory traversal vulnerability in a proprietary FTP client (CAN-2004-1376) which is also present in gftp, a GTK+ FTP client. A malicious server could provide a specially crafted filename that could cause arbitrary files to be overwritten or created by the client.
A Secunia Advisory reports:
Michael Holzt has discovered a vulnerability in Opera, which can be exploited by malicious people to trick users into executing malicious files.
The vulnerability is caused due to an error in the processing of "data:" URIs, causing wrong information to be shown in a download dialog. This can be exploited by e.g. a malicious website to trick users into executing a malicious file by supplying a specially crafted "data:" URI.
Giovanni Delvecchio reports:
Opera for linux uses "kfmclient exec" as "Default Application" to handle saved files. This could be used by malicious remote users to execute arbitrary shell commands on a target system.
The PL/PgSQL parser in postgresql is vulnerable to several buffer overflows. These could be exploited by a remote attacker to execute arbitrary code with the permissions of the postgresql server by running a specially crafted query.
Several input validation errors exist in AWStats that allow a
remote unauthenticated attacker to execute arbitrary commands
with the priviliges of the web server. These programming
errors involve CGI parameters including
loadplugin
, logfile
,
pluginmode
, update
, and possibly
others.
Additionally, the debug
and other CGI parameters
may be used to cause AWStats to disclose AWStats and system
configuration information.
PowerDNS is vulnerable to a temporary denial-of-service vulnerability that can be triggered using a random stream of bytes.
Max Vozeler discovered several format string vulnerabilities in the movemail utility of Emacs. They can be exploited when connecting to a malicious POP server and can allow an attacker can execute arbitrary code under the privileges of the user running Emacs.
A No System Group security advisory reports that ngircd is
vulnerable to a format string vulnerability in the
Log_Resolver()
function of log.c, if IDENT
support is enabled. This could allow a remote attacker to
execute arbitrary code with the permissions of the ngircd
daemon, which is root
by default.
Note: By default the FreeBSD ngircd port does not enable IDENT support.
Florian Westphal discovered a buffer overflow in ngircd which can be used remotely crash the server and possibly execute arbitrary code.
Mark J Cox reports:
Graham Dumpleton discovered a flaw which can affect anyone using the publisher handle of the Apache Software Foundation mod_python. The publisher handle lets you publish objects inside modules to make them callable via URL. The flaw allows a carefully crafted URL to obtain extra information that should not be visible (information leak).
A directory traversal vulnerability in mailman allow remote attackers to read arbitrary files due to inadequate input sanitizing. This could, among other things, lead remote attackers to gaining access to the mailman configuration database (which contains subscriber email addresses and passwords) or to the mail archives for private lists.
Erik Sjölund discovered several issues in enscript: it suffers from several buffer overflows, quotes and shell escape characters are insufficiently sanitized in filenames, and it supported taking input from an arbitrary command pipe, with unwanted side effects.
John Heasman and others disovered that non-privileged users
could use the LOAD
extension to load arbitrary
libraries into the postgres server process space. This
could be used by non-privileged local users to execute
arbitrary code with the privileges of the postgresql
server.
An Ethreal Security Advisories reports:
Issues have been discovered in the following protocol dissectors:
- The COPS dissector could go into an infinite loop. CVE: CAN-2005-0006
- The DLSw dissector could cause an assertion. CVE: CAN-2005-0007
- The DNP dissector could cause memory corruption. CVE: CAN-2005-0008
- The Gnutella dissector could cuase an assertion. CVE: CAN-2005-0009
- The MMSE dissector could free statically-allocated memory. CVE: CAN-2005-0010
- The X11 dissector is vulnerable to a string buffer overflow. CVE: CAN-2005-0084
Impact: It may be possible to make Ethereal crash or run arbitrary code by injecting a purposefully malformed packet onto the wire or by convincing someone to read a malformed packet trace file.
The squid patches page notes:
This patch addresses a HTTP protocol mismatch related to oversized reply headers. In addition it enhances the cache.log reporting on reply header parsing failures to make it easier to track down which sites are malfunctioning.
It is believed that this bug may lead to cache pollution or allow access controls to be bypassed.
According to Python Security Advisory PSF-2005-001,
The Python development team has discovered a flaw in the
SimpleXMLRPCServer
library module which can give remote attackers access to internals of the registered object or its module or possibly other modules. The flaw only affects Python XML-RPC servers that use theregister_instance()
method to register an object without a_dispatch()
method. Servers using onlyregister_function()
are not affected.On vulnerable XML-RPC servers, a remote attacker may be able to view or modify globals of the module(s) containing the registered instance's class(es), potentially leading to data loss or arbitrary code execution. If the registered object is a module, the danger is particularly serious. For example, if the registered module imports the
os
module, an attacker could invoke theos.system()
function.
Note: This vulnerability affects your
system only if you're running
SimpleXMLRPCServer
-based server. This isn't
harmful at all if you don't run any internet server written
in Python or your server doesn't serve in XML-RPC protocol.
Kevin Finisterre discovered bugs in perl's I/O debug support:
sperl
or suidperl
). As a
result, a local attacker may be able to gain elevated
privileges. (CVE-2005-0155)Note: By default, no set-user-ID perl
binary is installed. An administrator must enable it
manually at build time with the ENABLE_SUIDPERL
port flag.
The newsgrab script uses insecure permissions during the creation of the local output directory and downloaded files.
After a file is created, permissions on it are set using the mode value of the newsgroup posting. This can potentially be a problem when the mode is not restrictive enough. In addition, the output directory is created with world writable permissions allowing other users to drop symlinks or other files at that location.
The newsgrab script creates files by using the names provided in the newsgroup messages in a perl open() call. This is done without performing any security checks to prevent a directory traversal. A specially crafted newsgroup message could cause newsgrab to drop an attachment anywhere on the file system using the permissions of the user running the script.
The newspost program uses a function named socket_getline to read server responses from the network socket. Unfortunately this function does not check the length of the buffer in which the read data is stored and only stops reading when a newline character is found.
A malicious NNTP server could use this bug to cause a buffer overflow by sending an overly long response. Such an overflow allows arbitrary code to be executed, with the privileges of the newspost process, on the affected systems.
The newsfetch program uses the sscanf function to read information from server responses into static memory buffers. Unfortunately this is done without any proper bounds checking. As a result long server responses may cause an overflow when a newsgroup listing is requested from an NNTP server.
According to the Squid Proxy Cache Security Update Advisory SQUID-2005:3,
The WCCP recvfrom() call accepts more data than will fit in the allocated buffer. An attacker may send a larger-than-normal WCCP message to Squid and overflow this buffer.
Severity:
The bug is important because it allows remote attackers to crash Squid, causing a disription in service. However, the bug is exploitable only if you have configured Squid to send WCCP messages to, and expect WCCP replies from, a router.
Sites that do not use WCCP are not vulnerable.
Note that while the default configuration of the FreeBSD squid port enables WCCP support in general, the default configuration supplied does not actually configure squid to send and receive WCCP messages.
An iDEFENSE Security Advisory reports:
Remote exploitation of a buffer overflow vulnerability in the xpdf PDF viewer included in multiple Unix and Linux distributions could allow for arbitrary code execution as the user viewing a PDF file.
The vulnerability specifically exists due to insufficient bounds checking while processing a PDF file that provides malicious values in the /Encrypt /Length tag. The offending code can be found in the
Decrypt::makeFileKey2
function in the source file xpdf/Decrypt.cc.
Martin Joey
Schulze reports:
Erik Sjöund discovered that zhcon, a fast console CJK system using the Linux framebuffer, accesses a user-controlled configuration file with elevated privileges. Thus, it is possible to read arbitrary files.
When installed from the FreeBSD Ports Collection, zhcon is installed set-user-ID root.
Martin Joey
Schulze reports:
Max Vozeler discovered an integer overflow in the helper application camel-lock-helper which runs setuid root or setgid mail inside of Evolution, a free groupware suite. A local attacker can cause the setuid root helper to execute arbitrary code with elevated privileges via a malicious POP server.
An LSS Security Advisory reports:
When a denial of service attack is detected, mod_dosevasive will, among other things, create a temporary file which it will use to trace actions from the offensive IP address. This file is insecurely created in /tmp and it's name is easily predictable.
It is then easy for an attacker to create arbitrary files in any directory that the user under which apache runs has privileges to write.
[...] once the target file is opened, there is a race attack (although difficult to exploit) which can lead to mod_dosevasive overwriting any file that the user under which apache runs has privileges to write.
The squid patches page notes:
This patch makes Squid considerably stricter while parsing the HTTP protocol.
- A Content-length header should only appear once in a valid request or response. Multiple Content-length headers, in conjunction with specially crafted requests, may allow Squid's cache to be poisoned with bad content in certain situations.
- CR characters is only allowed as part of the CR NL line terminator, not alone. This to ensure that all involved agrees on the structure of HTTP headers.
- Rejects requests/responses that have whitespace in an HTTP header name.
To enable these strict parsing rules, update to at least
squid-2.5.7_9 and specify relaxed_header_parser
off
in squid.conf.
A Bugzilla advisory states:
This advisory covers a single cross-site scripting issue that has recently been discovered and fixed in the Bugzilla code: If a malicious user links to a Bugzilla site using a specially crafted URL, a script in the error page generated by Bugzilla will display the URL unaltered in the page, allowing scripts embedded in the URL to execute.
A Secunia Research advisory reports:
Secunia Research has reported a vulnerability in multiple browsers, which can be exploited by malicious people to spoof the content of websites.
The problem is that a website can inject content into another site's window if the target name of the window is known. This can e.g. be exploited by a malicious website to spoof the content of a pop-up window opened on a trusted website.
Secunia has constructed a test, which can be used to check if your browser is affected by this issue: http://secunia.com/multiple_browsers_window_injection_vulnerability_test/
A workaround for Mozilla-based browsers is available.
Manigandan Radhakrishnan discovered a security
vulnerability in YAMT which can lead to execution of
arbitrary commands with the privileges of the user running
YAMT when sorting based on MP3 tags. The problem exist in
the id3tag_sort()
routine which does not
properly sanitize the artist tag from the MP3 file before
using it as an argument to the mv command.
According to a whitepaper published by Sanctum, Inc., it is possible to mount cache poisoning attacks against, among others, squid proxies by inserting false replies into the HTTP stream.
The squid patches page notes:
This patch additionally strengthens Squid from the HTTP response attack described by Sanctum.
A Hyperdose Security Advisory reports:
Horde contains two XSS attacks that can be exploited through GET requests. Once exploited, these requests could be used to execute any javascript commands in the context of that user, potentially including but not limited to reading and deleting email, and stealing auth tokens.
Andrew V. Samoilov reported several vulnerabilities that were corrected in MidnightCommand 4.6.0:
Jeroen van Wolffelaar reports that the Perl module File::Path contains a race condition wherein traversed directories and files are temporarily made world-readable/writable.
Marc Schoenefeld reports:
Opera 7.54 is vulnerable to leakage of the java sandbox, allowing malicious applets to gain unacceptable privileges. This allows them to be used for information gathering (spying) of local identity information and system configurations as well as causing annoying crash effects.
Opera 754 [sic] which was released Aug 5,2004 is vulnerable to the XSLT processor covert channel attack, which was corrected with JRE 1.4.2_05 [released in July 04], but in disadvantage to the users the opera packaging guys chose to bundle the JRE 1.4.2_04 [...]
Internal pointer DoS exploitation: Opera.jar contains the opera replacement of the java plugin. It therefore handles communication between javascript and the Java VM via the liveconnect protocol. The public class EcmaScriptObject exposes a system memory pointer to the java address space, by constructing a special variant of this type an internal cache table can be polluted by false entries that infer proper function of the JSObject class and in the following proof-of-concept crash the browser.
Exposure of location of local java installation Sniffing the URL classpath allows to retrieve the URLs of the bootstrap class path and therefore the JDK installation directory.
Exposure of local user name to an untrusted applet An attacker could use the sun.security.krb5.Credentials class to retrieve the name of the currently logged in user and parse his home directory from the information which is provided by the thrown java.security.AccessControlException.
A sudo bug report says:
sudo doesn't unset the CDPATH variable, which leads to possible security problems.
An iDEFENSE Security Advisory states:
Multiple vulnerabilities have been found in Fcron.
- File contents disclosure
- Configuration Bypass Vulnerability
- File Removal and Empty File Creation Vulnerability
- Information Disclosure Vulnerability
An NGSSoftware Insight Security Research Advisory reports:
Two vulnerabilities have been discovered in RealPlayer which may potentially be leveraged to allow remote code execution, or may used in combination with the Real Metadata Package File Deletion vulnerability to reliably delete files from a users system.
Pavel Kankovsky reports:
Imlib affected by a variant of CAN-2004-0782 too.
I've discovered more vulnerabilities in Imlib (1.9.13). In particular, it appears to be affected by a variant of Chris Evans' libXpm flaw #1 (CAN-2004-0782, see http://scary.beasts.org/security/CESA-2004-003.txt). Look at the attached image, it kills ee on my 7.3.
The flaws also affect imlib2.
eGroupWare contains a bug in the JiNN component that allows a remote attacker to download arbitrary files.
An advisory published by Richard Stanway describes numerous critical vulnerabilities in the Quake II engine:
Due to unchecked input at various stages in the server, remote users are able to cause the server to crash, reveal sensitive information or potentially execute arbitrary code.
Konversation comes with Perl scripts that do not properly escape shell characters on executing a script. This makes it possible to attack Konversation with shell script command injection.
The LDAP authentication helper did not strip leading or trailing spaces from the login name. According to the squid patches page:
LDAP is very forgiving about spaces in search filters and this could be abused to log in using several variants of the login name, possibly bypassing explicit access controls or confusing accounting.
Workaround: Block logins with spaces
acl login_with_spaces proxy_auth_regex [:space:] http_access deny login_with_spaces
Kenshi Muto discovered that the CUPS server would enter an
infinite loop when processing a URL containing
./..
A US-CERT vulnerability note reports:
An Integer overflow in the LibTIFF library may allow a remote attacker to cause a divide-by-zero error that results in a denial-of-service condition.
infamous41md reports:
zgv uses malloc() frequently to allocate memory for storing image data. When calculating how much to allocate, user supplied data from image headers is multiplied and/or added without any checks for arithmetic overflows. We can overflow numerous calculations, and cause small buffers to be allocated. Then we can overflow the buffer, and eventually execute code. There are a total of 11 overflows that are exploitable to execute arbitrary code.
These bugs exist in both zgv and xzgv.
In a Mozilla bug report, Daniel Kleinsinger writes:
I was comparing treatment of attachments opened directly from emails on different platforms. I discovered that Linux builds save attachments in /tmp with world readable rights. This doesn't seem like a good thing. Couldn't someone else logged onto the same machine read your attachments?
This could expose the contents of downloaded files or email attachments to other users on a multi-user system.
An iDEFENSE Security Advisory reports:
Remote exploitation of an input validation vulnerability in AWStats allows attackers to execute arbitrary commands under the privileges of the web server.
The problem specifically exists when the application is running as a CGI script on a web server. The "configdir" parameter contains unfiltered user-supplied data that is utilized in a call to the Perl routine open()...
Successful exploitation allows remote attackers to execute arbitrary commands under the privileges of the web server. This can lead to further compromise as it provides remote attackers with local access.
An iDEFENSE Security Advisory reports:
Remote exploitation of a buffer overflow vulnerability in The ImageMagick's Project's ImageMagick PSD image-decoding module could allow an attacker to execute arbitrary code.
Exploitation may allow attackers to run arbitrary code on a victim's computer if the victim opens a specially formatted image. Such images could be delivered by e-mail or HTML, in some cases, and would likely not raise suspicion on the victim's part. Exploitation is also possible when a web-based application uses ImageMagick to process user-uploaded image files.
D. J. Bernstein reports that Bartlomiej Sieka has discovered several security vulnerabilities in lppasswd, which is part of CUPS. In the following excerpt from Bernstein's email, CVE names have been added for each issue:
First, lppasswd blithely ignores write errors in fputs(line,outfile) at lines 311 and 315 of lppasswd.c, and in fprintf(...) at line 346. An attacker who fills up the disk at the right moment can arrange for /usr/local/etc/cups/passwd to be truncated. (CAN-2004-1268)
Second, if lppasswd bumps into a file-size resource limit while writing passwd.new, it leaves passwd.new in place, disabling all subsequent invocations of lppasswd. Any local user can thus disable lppasswd... (CAN-2004-1269)
Third, line 306 of lppasswd.c prints an error message to stderr but does not exit. This is not a problem on systems that ensure that file descriptors 0, 1, and 2 are open for setuid programs, but it is a problem on other systems; lppasswd does not check that passwd.new is different from stderr, so it ends up writing a user-controlled error message to passwd if the user closes file descriptor 2. (CAN-2004-1270)
Note: The third issue, CVE-2004-1270, does not affect FreeBSD 4.6-RELEASE or later systems, as these systems ensure that the file descriptors 0, 1, and 2 are always open for set-user-ID and set-group-ID programs.
Ariel Berkman has discovered a buffer overflow vulnerability in CUPS's HPGL input driver. This vulnerability could be exploited to execute arbitrary code with the permission of the CUPS server by printing a specially crated HPGL file.
The Debian Security Team reports:
Javier Fernández-Sanguino Peña from the Debian Security Audit Project discovered a temporary file vulnerability in the mysqlaccess script of MySQL that could allow an unprivileged user to let root overwrite arbitrary files via a symlink attack and could also could unveil the contents of a temporary file which might contain sensitive information.
Yosef Klein and Limin Wang have found a buffer overflow vulnerability in unrtf that can allow an attacker to execute arbitrary code with the permissions of the user running unrtf, by running unrtf on a specially crafted rtf document.
Maurycy Prodeus reports a critical vulnerability in Mozilla-based browsers:
Mozilla browser supports NNTP urls. Remote side is able to trigger news:// connection to any server. I found a flaw in NNTP handling code which may cause heap overflow and allow remote attacker to execute arbitrary code on client machine.
Yuri D'Elia has found a buffer overflow vulnerability in mpg123's parsing of frame headers in input streams. This vulnerability can potentially lead to execution of arbitrary code with the permissions of the user running mpg123, if the user runs mpg123 on a specially crafted MP2 or MP3 file.
The squid patches page notes:
WCCP_I_SEE_YOU messages contain a 'number of caches' field which should be between 1 and 32. Values outside that range may crash Squid if WCCP is enabled, and if an attacker can spoof UDP packets with the WCCP router's IP address.
The squid patches page notes:
A malicious gopher server may return a response with very long lines that cause a buffer overflow in Squid.
Workaround: Since gopher is very obscure these days, do not allow Squid to any gopher servers. Use an ACL rule like:
acl Gopher proto gopher http_access deny Gopher
A xine security announcement states:
A heap overflow has been found in the DVD subpicture decoder of xine-lib. This can be used for a remote heap overflow exploit, which can, on some systems, lead to or help in executing malicious code with the permissions of the user running a xine-lib based media application.
A xine security announcement states:
Several string overflows on the stack have been fixed in xine-lib, some of them can be used for remote buffer overflow exploits leading to the execution of arbitrary code with the permissions of the user running a xine-lib based media application.
Stack-based string overflows have been found:
- in the code which handles VideoCD MRLs
- in VideoCD code reading the disc label
- in the code which parses text subtitles and prepares them for display
A xine security announcement states:
Multiple vulnerabilities have been found and fixed in the Real-Time Streaming Protocol (RTSP) client for RealNetworks servers, including a series of potentially remotely exploitable buffer overflows. This is a joint advisory by the MPlayer and xine teams as the code in question is common to these projects.
Severity: High (arbitrary remote code execution under the user ID running the player) when playing Real RTSP streams. At this time, there is no known exploit for these vulnerabilities.
A flaw in HylaFAX may allow an attacker to bypass normal authentication by spoofing their DNS PTR records.
Steve Kemp has found buffer overflows in the handling of the command line flag -KCONV and the XSHISENLIB environment variable. Ulf Härnhammer has detected an unbounded copy from the GECOS field to a char array. All overflows can be exploited to gain group games privileges.
The setuid root elvprsv utility, used to preserve recovery helvis files, can be abused by local users to delete with root privileges.
The problem is that elvprsv deletes files when it thinks they have become corrupt. When elvprsv is pointed to a normal file then it will almost always think the file is corrupt and deletes it. This behavior may be exploited by local attackers to delete critical files.
Once a recovery file has been preserved by the setuid root elvprsv utility it is placed in a worldreadable directory with worldreadable permissions. This possibly allows sensitive information to leak.
In addition to this information leak, it is possible for users to recover files that belong to other users by using elvrec, another setuid root binary.
dillo contains a format string vulnerability which could lead to execution of arbitrary code simply by viewing a web page or opening a HTML file.
When downloading a batch of files from an FTP server the mget command does not check for directory escapes. A specially crafted file on the FTP server could then potentially overwrite an existing file of the user.
Dmitry V. Levin found a potential integer overflow in the tiffdump utility which could lead to execution of arbitrary code. This could be exploited by tricking an user into executing tiffdump on a specially crafted tiff image.
In an iDEFENSE Security Advisory infamous41md reports:
Remote exploitation of a heap-based buffer overflow vulnerability within the LibTIFF package could allow attackers to execute arbitrary code.
The vulnerability specifically exists due to insufficient validation of user-supplied data when calculating the size of a directory entry. A TIFF file includes a number of directory entry header fields that describe the data in the file. Included in these entries is an entry count and offset value that are calculated to determine the size and location of the data for that entry.
Ciaran McCreesh discovered news ways in which a VIM modeline can be used to trojan a text file. The patch by Bram Moolenaar reads:
Problem: Unusual characters in an option value may cause unexpected behavior, especially for a modeline. (Ciaran McCreesh)
Solution: Don't allow setting termcap options or 'printdevice' or 'titleold' in a modeline. Don't list options for "termcap" and "all" in a modeline. Don't allow unusual characters in 'filetype', 'syntax', 'backupext', 'keymap', 'patchmode' and 'langmenu'.
Note: It is generally recommended that VIM
users use set nomodeline
in
~/.vimrc
to avoid the possibility of trojaned
text files.
Danny Lungstrom has found two buffer overflow vulnerabilities in pcal which can lead to execution of arbitrary code by making a user run pcal on a specially crafted calendar file.
1. The function host_aton() can overflow a buffer if it is presented with an illegal IPv6 address that has more than 8 components.
2. The second report described a buffer overflow in the function spa_base64_to_bits(), which is part of the code for SPA authentication.
A buffer overflow vulnerability exists in the playlist processing of mpg123. A specially crafted playlist entry can cause a stack overflow that can be used to inject arbitrary code into the mpg123 process.
Note that a malicious playlist, demonstrating this vulnerability, was released by the bug finder and may be used as a template by attackers.
A buffer overflow vulnerability has been detected in the greed URL handling code. This bug can especially be a problem when greed is used to process GRX (GetRight) files that originate from untrusted sources.
The bug finder, Manigandan Radhakrishnan, gave the following description:
Here are the bugs. First, in main.c, DownloadLoop() uses strcat() to copy an input filename to the end of a 128-byte COMMAND array. Second, DownloadLoop() passes the input filename to system() without checking for special characters such as semicolons.
Two buffer overflow vulnerabilities where detected. Both issues can be used by local users to gain group games privileges on affected systems.
The first overflow exists in the map name handling and can be triggered when a very long name is given to the program during command-line execution
The second overflow exists in the username processing while writing the players score to disk. Excessivly long usernames, set via the USER environment variable, are stored without any length checks in a memory buffer.
Timo Sirainen reports:
There are various bugs in up-imapproxy which can crash it. Since up-imapproxy runs in a single process with each connection handled in a separate thread, any crash kills all the connections and stops listening for new ones.
In 64bit systems it might be possible to make it leak data (mails, passwords, ..) from other connections to attacker's connection. However I don't think up-imapproxy actually works in any 64bit system so this is just a theoretical problem.
Albert Puigsech Galicia reports that Konqueror (more specifically kio_ftp) and Microsoft Internet Explorer are vulnerable to a FTP command injection vulnerability which can be exploited by tricking an user into clicking a specially crafted FTP URI.
It is also reported by Ian Gulliver and Emanuele Balla that this vulnerability can be used to tricking a client into sending out emails without user interaction.
A Secunia Security Advisory reports that Javier Fernández-Sanguino Peña has found temporary file creation vulnerabilities in the fixps and psmandup scripts which are part of a2ps. These vulnerabilities could lead to an attacker overwriting arbitrary files with the credentials of the user running the vulnerable scripts.
Due to a buffer overflow in the open_aiff_file function in demux_aiff.c, a remote attacker is able to execute arbitrary code via a modified AIFF file.
José Antonio Calvo discovered a bug in the Jabber 1.x server. According to Matthias Wimmer:
Without this patch, it is possible to remotly crash jabberd14, if there is access to one of the following types of network sockets:
- Socket accepting client connections
- Socket accepting connections from other servers
- Socket connecting to an other Jabber server
- Socket accepting connections from server components
- Socket connecting to server components
This is any socket on which the jabberd server parses XML!
The problem existed in the included expat XML parser code. This patch removes the included expat code from jabberd14 and links jabberd against an installed version of expat.
Applying an empty ACL list results in unexpected behavior: anything will match an empty ACL list. For example,
The meaning of the configuration gets very confusing when we encounter empty ACLs such as
acl something src "/path/to/empty_file.txt"
http_access allow something somewheregets parsed (with warnings) as
http_access allow somewhere
And similarily if you are using proxy_auth acls without having any auth schemes defined.
An Ethreal Security Advisories reports:
Issues have been discovered in the following protocol dissectors:
- Matthew Bing discovered a bug in DICOM dissection that could make Ethereal crash.
- An invalid RTP timestamp could make Ethereal hang and create a large temporary file, possibly filling available disk space.
- The HTTP dissector could access previously-freed memory, causing a crash.
- Brian Caswell discovered that an improperly formatted SMB packet could make Ethereal hang, maximizing CPU utilization.
Impact: It may be possible to make Ethereal crash or run arbitrary code by injecting a purposefully malformed packet onto the wire or by convincing someone to read a malformed packet trace file.
An iDEFENSE Security Advisory reports:
Remote exploitation of a buffer overflow vulnerability in the xpdf PDF viewer, as included in multiple Linux distributions, could allow attackers to execute arbitrary code as the user viewing a PDF file. The offending code can be found in the Gfx::doImage() function in the source file xpdf/Gfx.cc.
An iDEFENSE Security Advisory reports:
Remote exploitation of a buffer overflow in version 5.09 of Adobe Acrobat Reader for Unix could allow for execution of arbitrary code.
The vulnerability specifically exists in a the function mailListIsPdf(). This function checks if the input file is an email message containing a PDF. It unsafely copies user supplied data using strcat into a fixed sized buffer.
A Debian security advisory reports:
A problem has been discovered in ecartis, a mailing-list manager, which allows an attacker in the same domain as the list admin to gain administrator privileges and alter list settings.
iDEFENSE and the MPlayer Team have found multiple vulnerabilities in MPlayer:
These vulnerabilities could allow a remote attacker to execute arbitrary code as the user running MPlayer. The problem in the pnm streaming code also affects xine.
A MIT krb5 Security Advisory reports:
The MIT Kerberos 5 administration library (libkadm5srv) contains a heap buffer overflow in password history handling code which could be exploited to execute arbitrary code on a Key Distribution Center (KDC) host. The overflow occurs during a password change of a principal with a certain password history state. An administrator must have performed a certain password policy change in order to create the vulnerable state.
An authenticated user, not necessarily one with administrative privileges, could execute arbitrary code on the KDC host, compromising an entire Kerberos realm.
Greg MacManus, iDEFENSE Labs reports:
Remote exploitation of an integer overflow vulnerability in the smbd daemon included in Samba 2.0.x, Samba 2.2.x, and Samba 3.0.x prior to and including 3.0.9 could allow an attacker to cause controllable heap corruption, leading to execution of arbitrary commands with root privileges.
Successful remote exploitation allows an attacker to gain root privileges on a vulnerable system. In order to exploit this vulnerability an attacker must possess credentials that allow access to a share on the Samba server. Unsuccessful exploitation attempts will cause the process serving the request to crash with signal 11, and may leave evidence of an attack in logs.
Secunia reports:
Multiple vulnerabilities have been reported in PHP, which can be exploited to gain escalated privileges, bypass certain security restrictions, gain knowledge of sensitive information, or compromise a vulnerable system.
When a user is granted access to a database with a name containing an underscore and the underscore is not escaped then that user might also be able to access other, similarly named, databases on the affected system.
The problem is that the underscore is seen as a wildcard by MySQL and therefore it is possible that an admin might accidently GRANT a user access to multiple databases.
Dean Ellis reported a denial of service vulnerability in the MySQL server:
Multiple threads ALTERing the same (or different) MERGE tables to change the UNION eventually crash the server or hang the individual threads.
Note that a script demonstrating the problem is included in the MySQL bug report. Attackers that have control of a MySQL account can easily use a modified version of that script during an attack.
A special crafted MySQL FTS request can cause the server to crash. Malicious MySQL users can abuse this bug in a denial of service attack against systems running an affected MySQL daemon.
Note that because this bug is related to the parsing of requests, it may happen that this bug is triggered accidently by a user when he or she makes a typo.
The mysql_real_connect function doesn't properly handle DNS replies by copying the IP address into a buffer without any length checking. A specially crafted DNS reply may therefore be used to cause a buffer overflow on affected systems.
Note that whether this issue can be exploitable depends on the system library responsible for the gethostbyname function. The bug finder, Lukasz Wojtow, explaines this with the following words:
In glibc there is a limitation for an IP address to have only 4 bytes (obviously), but generally speaking the length of the address comes with a response for dns query (i know it sounds funny but read rfc1035 if you don't believe). This bug can occur on libraries where gethostbyname function takes length from dns's response
A Red Hat advisory reports:
Oleksandr Byelkin discovered that "ALTER TABLE ... RENAME" checked the CREATE/INSERT rights of the old table instead of the new one.
Table access restrictions, on the affected MySQL servers, may accidently or intentially be bypassed due to this bug.
A phpMyAdmin security announcement reports:
Command execution: since phpMyAdmin 2.6.0-pl2, on a system where external MIME-based transformations are activated, an attacker can put into MySQL data an offensive value that starts a shell command when browsed.
Enabling PHP safe mode
on the server can be used as
a workaround for this vulnerability.
A phpMyAdmin security announcement reports:
File disclosure: on systems where the UploadDir mecanism is active, read_dump.php can be called with a crafted form; using the fact that the sql_localfile variable is not sanitized can lead to a file disclosure.
Enabling PHP safe mode
on the server can be used as
a workaround for this vulnerability.
Jan Minar reports that there exists multiple vulnerabilities in wget:
Wget erroneously thinks that the current directory is a fair game, and will happily write in any file in and below it. Malicious HTTP response or malicious HTML file can redirect wget to a file that is vital to the system, and wget will create/append/overwrite it.
Wget apparently has at least two methods of ``sanitizing'' the potentially malicious data it receives from the HTTP stream, therefore a malicious redirects can pass the check. We haven't find a way to trick wget into writing above the parent directory, which doesn't mean it's not possible.
Malicious HTTP response can overwrite parts of the terminal so that the user will not notice anything wrong, or will believe the error was not fatal.
When browsing SMB shares with Konqueror, shares with authentication show up with hidden password in the browser bar. It is possible to store the URL as a shortcut on the desktop where the password is then available in plain text.
A malformed Referer
header field causes the Apache
ap_parse_uri_components function to discard it with the
result that a pointer is not initialized. The
mod_access_referer module does not take this into account
with the result that it may use such a pointer.
The null pointer vulnerability may possibly be used in a remote denial of service attack against affected Apache servers.
The squid-2.5 patches pages notes:
In certain conditions Squid returns random data as error messages in response to malformed host name, possibly leaking random internal information which may come from other requests.
The hide_cvsroot
and forbidden
configuration options are not properly honored by viewcvs
when exporting to a tar file which can lead to information
leakage.
cscope is vulnerable to a symlink attack which could lead to an attacker overwriting arbitrary files with the permissions of the user running cscope.
A LSS Security Advisory reports:
There is a buffer overflow vulnerability in getnickuserhost() function that is called when BNC is processing response from IRC server.
Vulnerability can be exploited if attacker tricks user to connect to his fake IRC server that will exploit this vulnerability. If the attacker has access to BNC proxy server, this vulnerability can be used to gain shell access on machine where BNC proxy server is set.
Jason Wies identified both rssh & scponly have a vulnerability that allows arbitrary command execution. He reports:
The problem is compounded when you recognize that the main use of rssh and scponly is to allow file transfers, which in turn allows a malicious user to transfer and execute entire custom scripts on the remote machine.
The environment variable HOME is copied without regard to buffer size, which can be used to gain elevated privilege if the binary is installed setgid games, and a string is read from the high score file without bounds check.
The port installs the binary without setgid, but with a world-writable high score file.
A HexView security advisory reports:
When zip performs recursive folder compression, it does not check for the length of resulting path. If the path is too long, a buffer overflow occurs leading to stack corruption and segmentation fault. It is possible to exploit this vulnerability by embedding a shellcode in directory or file name. While the issue is not of primary concern for regular users, it can be critical for environments where zip archives are re-compressed automatically using Info-Zip application.
If non-root access is enabled in sudoscript, any member of the ssers group can send a SIGHUP signal to any process.
Caused by improper bounds-checking of username and password in the C2S module, it is possible for an attacker to cause a remote buffer overflow. The server directly handles the userinput with SQL backend functions - malicious input may lead to buffer overflow.
Donato Ferrante reported an exploitable buffer overflow in this software package. Any user that can login with 'admin' privileges can abuse it, trough the $RedirectAll command, to execute arbitrary code.
Ludwig Nussel has discovered a buffer overflow vulnerability in unarj's handling of long filenames which could potentially lead to execution of arbitrary code with the permissions of the user running unarj.
unarj has insufficient checks for filenames that contain
..
. This can allow an attacker to overwrite
arbitrary files with the permissions of the user running
unarj.
The Sun Java Plugin capability in Java 2 Runtime Environment (JRE) 1.4.2_01, 1.4.2_04, and possibly earlier versions, does not properly restrict access between Javascript and Java applets during data transfer, which allows remote attackers to load unsafe classes and execute arbitrary code.
Buffer overflow vulnerabilities have been reported to exist in this software package. The vulnerabilities can be triggered by a remote server and can be used to inject malicious code in the ProZilla process.
To support MULTIAPPENDS the cmd_append handler uses the global stage array. This array is one of the things that gets destructed when the fatal() function is triggered. When the Cyrus IMAP code adds new entries to this array this is done with the help of the postfix increment operator in combination with memory allocation functions. The increment is performed on a global variable counting the number of allocated stages. Because the memory allocation function can fail and therefore internally call fatal() this construct is undefined arcording to ANSI C. This means that it is not clearly defined if the numstage counter is already increased when fatal() is called or not. While older gcc versions increase the counter after the memory allocation function has returned, on newer gcc versions (3.x) the counter gets actually increased before. In such a case the stage destructing process will try to free an uninitialised and maybe attacker supplied pointer. Which again could lead to remote code execution. (Because it is hard for an attacker to let the memory allocation functions fail in the right moment no PoC code for this problem was designed)
The argument parser of the fetch command suffers a bug very similiar to the partial command problem. Arguments like "body[p", "binary[p" or "binary[p" will be wrongly detected and the bufferposition can point outside of the allocated buffer for the rest of the parsing process. When the parser triggers the PARSE_PARTIAL macro after such a malformed argument was received this can lead to a similiar one byte memory corruption and allows remote code execution, when the heap layout was successfully controlled by the attacker.
Due to a bug within the argument parser of the partial command an argument like "body[p" will be wrongly detected as "body.peek". Because of this the bufferposition gets increased by 10 instead of 5 and could therefore point outside the allocated memory buffer for the rest of the parsing process. In imapd versions prior to 2.2.7 the handling of "body" or "bodypeek" arguments was broken so that the terminating ']' got overwritten by a '\0'. Combined the two problems allow a potential attacker to overwrite a single byte of malloc() control structures, which leads to remote code execution if the attacker successfully controls the heap layout.
When the option imapmagicplus is activated on a server the PROXY and LOGIN commands suffer a standard stack overflow, because the username is not checked against a maximum length when it is copied into a temporary stack buffer. This bug is especially dangerous because it can be triggered before any kind of authentification took place.
Multiple cross-site scripting vulnerabilities, caused by improper input parameter sanitizing, were detected in phpMyAdmin, which may enable an attacker to do cross-site scripting attacks.
An integer overflow condition in fetch(1) in the processing of HTTP headers can result in a buffer overflow.
A malicious server or CGI script can respond to an HTTP or HTTPS request in such a manner as to cause arbitrary portions of the client's memory to be overwritten, allowing for arbitrary code execution.
Caused by improper bounds checking of certain trans2 requests, there is a possible buffer overrun in smbd. The attacker needs to be able to create files with very specific Unicode filenames on the share to take advantage of this issue.
Hans Ulrich Niedermann reports:
The TWiki search function uses a user supplied search string to compose a command line executed by the Perl backtick (``) operator.
The search string is not checked properly for shell metacharacters and is thus vulnerable to search string containing quotes and shell commands.
IMPACT: An attacker is able to execute arbitrary shell commands with the privileges of the TWiki process.
A Gentoo Linux Security Advisory reports:
Florian Schilhabel of the Gentoo Linux Security Audit project found a format string vulnerability in Proxytunnel. When the program is started in daemon mode (-a [port]), it improperly logs invalid proxy answers to syslog.
A malicious remote server could send specially-crafted invalid answers to exploit the format string vulnerability, potentially allowing the execution of arbitrary code on the tunnelling host with the rights of the Proxytunnel process.
A Sudo Security Alerts reports:
A flaw in exists in sudo's environment sanitizing prior to sudo version 1.6.8p2 that could allow a malicious user with permission to run a shell script that utilized the bash shell to run arbitrary commands.
The Ruby CGI.rb module contains a bug which can cause the CGI module to go into an infinite loop, thereby causing a denial-of-service situation on the web server by using all available CPU time.
Karol Wiesek at iDEFENSE reports:
A remote attacker could cause an smbd process to consume abnormal amounts of system resources due to an input validation error when matching filenames containing wildcard characters.
Although samba.org classifies this as a DoS vulnerability, several members of the security community believe it may be exploitable for arbitrary code execution.
Gnats suffers from a format string bug, which may enable an attacker to execute arbitary code.
A SquirrelMail Security Notice reports:
There is a cross site scripting issue in the decoding of encoded text in certain headers. SquirrelMail correctly decodes the specially crafted header, but doesn't sanitize the decoded strings.
A siyahsapka.org advisory reads:
Hafiye-1.0 doesnt filter the payload when printing it to the terminal. A malicious attacker can send packets with escape sequence payloads to exploit this vulnerability.
If Hafiye has been started with -n packet count option , the vulnerability could allow remote code execution. For remote code execution the victim must press Enter after program exit.
Note that it appears that this bug can only be exploited in conjunction with a terminal emulator that honors the appropriate escape sequences.
Data supplied by a remote server is used as the format string instead of as parameters in a syslog() call. This may lead to crashes or potential running of arbitrary code. It is only a problem when running in daemon mode (very common) and when using some service types.
There exists a buffer overflow vulnerability in ImageMagick's EXIF parsing code which may lead to execution of arbitrary code.
It is possible for remote attackers to cause a denial-of-service scenario on Apache 2.0.52 and earlier by sending an HTTP GET request with a MIME header containing multiple lines full of whitespaces.
Socat Security Advisory 1 states:
socat up to version 1.4.0.2 contains a syslog() based format string vulnerability. This issue was originally reported by CoKi on 19 Oct.2004 http://www.nosystem.com.ar/advisories/advisory-07.txt. Further investigation showed that this vulnerability could under some circumstances lead to local or remote execution of arbitrary code with the privileges of the socat process.
infamous41md
reports that libxml contains multiple
buffer overflows in the URL parsing and DNS name resolving
functions. These vulnerabilities could lead to execution of
arbitrary code.
An AMaViS Security Announcement reports that a vulnerability exist in the Archive::Zip Perl module which may lead to bypass of malicious code in anti-virus programs by creating specially crafted ZIP files.
There is a buffer overflow in a function used by mod_include that may enable a local user to gain privileges of a httpd child. Only users that are able to create SSI documents can take advantage of that vulnerability.
The make_oidjoins_check script in the PostgreSQL RDBMS has insecure handling of temporary files, which could lead to an attacker overwriting arbitrary files with the credentials of the user running the make_oidjoins_check script.
infamous41md reports about the GD Graphics Library:
There is an integer overflow when allocating memory in the routine that handles loading PNG image files. This later leads to heap data structures being overwritten. If an attacker tricked a user into loading a malicious PNG image, they could leverage this into executing arbitrary code in the context of the user opening image.
There is a bug in SSH2 support that allows a server to execute malicious code on a connecting PuTTY client. This attack can be performed before host key verification happens, so a different machine -- man in the middle attack -- could fake the machine you are connecting to.
wzdftpd contains a potential remote Denial-of-Service.
There is a format string bug in rssh that enables an attacker to execute arbitrary code from an account configured to use rssh. On FreeBSD it is only possible to compromise the rssh running account, not root.
A Horde Team announcement states that a potential cross-site
scripting vulnerability in the help window has been
corrected. The vulnerability appears to involve the handling
of the topic
and module
parameters
of the help window template.
The bogofilter team has been provided with a test case of a malformatted (non-conformant) RFC-2047 encoded word that can cause bogofilter versions 0.92.7 and prior to try to write a NUL byte into a memory location that is either one byte past the end of a flex buffer or to a location that is the negative of the encoded word's start of payload data, causing a segmentation fault.
Chris Evans discovered several integer arithmetic overflows in the xpdf 2 and xpdf 3 code bases. The flaws have impacts ranging from denial-of-service to arbitrary code execution.
The Gaim team discovered denial-of-service vulnerabilities in the MSN protocol handler:
After accepting a file transfer request, Gaim will attempt to allocate a buffer of a size equal to the entire filesize, this allocation attempt will cause Gaim to crash if the size exceeds the amount of available memory.
Gaim allocates a buffer for the payload of each message received based on the size field in the header of the message. A malicious peer could specify an invalid size that exceeds the amount of available memory.
Sean infamous42md
reports:
When a remote server provides a large "content-length" header value, Gaim will attempt to allocate a buffer to store the content, however this allocation attempt will cause Gaim to crash if the length exceeds the amount of possible memory. This happens when reading profile information on some protocols. It also happens when smiley themes are installed via drag and drop.
Sean infamous42md
reports several situations in gaim
that may result in exploitable buffer overflows:
Sean infamous42md
reports that a malicious GroupWise
messaging server may be able to exploit a heap buffer
overflow in gaim, leading to arbitrary code execution.
The Gaim Security Issues page documents a problem with installing smiley themes from an untrusted source:
To install a new smiley theme, a user can drag a tarball from a graphical file manager, or a hypertext link to one from a web browser. When a tarball is dragged, Gaim executes a shell command to untar it. However, it does not escape the filename before sending it to the shell. Thus, a specially crafted filename could execute arbitrary commands if the user could be convinced to drag a file into the smiley theme selector.
Due to a buffer overflow in the MSN protocol support for gaim 0.79 to 1.0.1, it is possible for remote clients to do a denial-of-service attack on the application. This is caused by an unbounded copy operation, which writes to the wrong buffer.
It is possible for clients to use any cipher suite configured by the virtual host, whether or not a certain cipher suite is selected for a specific directory. This might result in clients using a weaker encryption than originally configured.
Carlos Barros reports that mpg123 contains two buffer overflows. These vulnerabilities can potentially lead to execution of arbitrary code.
The first buffer overflow can occur when mpg123 parses a URL with a user-name/password field that is more than 256 characters long. This problem can be triggered either locally or remotely via a specially crafted play list. The second potential buffer overflow may be triggered locally by a specially crafted symlink to the mpg123 binary. This problem is not as serious, since mpg123 is not installed setuid by default.
The Apache HTTP Server 2.0.51 release notes report that the following issues have been fixed:
A segfault in mod_ssl which can be triggered by a malicious remote server, if proxying to SSL servers has been configured. [CAN-2004-0751]
A potential infinite loop in mod_ssl which could be triggered given particular timing of a connection abort. [CAN-2004-0748]
From the phpMyAdmin 2.6.0p2 release notes:
If PHP is not running in safe mode, a problem in the MIME-based transformation system (with an "external" transformation) allows to execute any command with the privileges of the web server's user.
cabextract has insufficient checks for file names that
contain ../
. This can cause files to be extracted to
the parent directory.
Rudolf Polzer reports:
a2ps builds a command line for file() containing an unescaped version of the file name, thus might call external programs described by the file name. Running a cronjob over a public writable directory a2ps-ing all files in it - or simply typing "a2ps *.txt" in /tmp - is therefore dangerous.
Niels Heinen reports that ifmail allows one to specify a configuration file. Since ifmail runs set-user-ID `news', this may allow a local attacker to write to arbitrary files or execute arbitrary commands as the `news' user.
A Computer Academic Underground advisory describes the consequences of imwheel's handling of the process ID file (PID file):
imwheel exclusively uses a predictably named PID file for management of multiple imwheel processes. A race condition exists when the -k command-line option is used to kill existing imwheel processes. This race condition may be used by a local user to Denial of Service another user using imwheel, lead to resource exhaustion of the host system, or append data to arbitrary files.
A remote attacker is able to cause a denial-of-service situation, when NTLM authentication is enabled in squid. NTLM authentication uses two functions which lack correct offset checking.
Fernando Quintero reports that Cacti 0.8.5a suffers from a SQL injection attack where an attacker can change the password for any Cacti user. This attack is not possible if the PHP option magic_quotes_gpc is set to On, which is the default for PHP in FreeBSD.
A OpenPKG Security Advisory reports:
Triggered by a report to Packet Storm from Virulent, a format string vulnerability was found in mod_ssl, the Apache SSL/TLS interface to OpenSSL, version (up to and including) 2.8.18 for Apache 1.3. The mod_ssl in Apache 2.x is not affected. The vulnerability could be exploitable if Apache is used as a proxy for HTTPS URLs and the attacker established a own specially prepared DNS and origin server environment.
Tor has various remote crashes which could lead to a remote denial-of-service and be used to defeat clients anonymity. It is not expected that these vulnerabilities are exploitable for arbitrary code execution.
Caused by improper filtering of HTML code in the status display, it is possible for a remote user to execute scripting code in the target user's browser.
It is possible to execute remote code simply using HTTP request plus 31 headers followed by a shellcode that will be executed directly.
A remote attacker may be able to crash the freeRADIUS Server due to three independant bugs in the function which does improper checking values while processing RADIUS attributes.
Amit Klein reports about Xerces-C++:
An attacker can craft a malicious XML document, which uses XML attributes in a way that inflicts a denial of service condition on the target machine (XML parser). The result of this attack is that the XML parser consumes all the CPU.
Pages in the administration panel of Wordpress are vulnerable for XSS attacks.
Dmitry V. Levin discovered numerous integer overflow bugs in libtiff. Most of these bugs are related to memory management, and are believed to be exploitable for arbitrary code execution.
Certain methods of authenticated remote printing in CUPS can disclose user names and passwords in the log files.
A workaround for this problem is to set more strict access permissions on the CUPS logfiles.
The audio player Zinf is vulnerable to a buffer-overflow bug in the management of the playlist files.
Chris Evans discovered several heap buffer overflows in libtiff's RLE decoder. These overflows could be triggered by a specially-crafted TIFF image file, resulting in an application crash and possibly arbitrary code execution.
From Gentoo advisory GLSA 200410-01:
sharutils contains two buffer overflows. Ulf Harnhammar discovered a buffer overflow in shar.c, where the length of data returned by the wc command is not checked. Florian Schilhabel discovered another buffer overflow in unshar.c.
An attacker could exploit these vulnerabilities to execute arbitrary code as the user running one of the sharutils programs.
Caused by an untested return value, and a resulting null pointer dereference, it is possible for an attacker to crash the application. However, the attacker must first hijack the connection between Mail Notification and the Gmail or IMAP server.
The Squid-2.5 patches page notes:
If a certain malformed SNMP request is received squid restarts with a Segmentation Fault error.
This only affects squid installations where SNMP is explicitly enabled via "make config". As a workaround, SNMP can be disabled by defining "snmp_port 0" in squid.conf.
Squid security advisory SQUID-2008:1 explains that Squid-3 versions up to and including Squid-3.0.STABLE6 are affected by this error, too.
The Cyrus SASL DIGEST-MD5 plugin contains a potential buffer overflow when quoting is required in the output.
The Cyrus SASL library, libsasl, contains functions which may load dynamic libraries. These libraries may be loaded from the path specified by the environmental variable SASL_PATH, which in some situations may be fully controlled by a local attacker. Thus, if a set-user-ID application (such as chsh) utilizes libsasl, it may be possible for a local attacker to gain superuser privileges.
The script vulnerabilities can only be exposed with certain browsers and allow XSS attacks when viewing HTML messages with the HTML MIME viewer
Jon Nistor reported that the FreeBSD port of bmon was installed set-user-ID root, and executes commands using relative paths. This could allow local user to easily obtain root privileges.
Patric Hornik reports on a problem in the certificate chain verification procedures of GnuTLS that may result in a denial-of-service vulnerability:
The certificate chain should be verified from last root certificate to the first certificate. Otherwise a lot of unauthorized CPU processing can be forced to check certificate signatures signed with arbitrary RSA/DSA keys chosen by attacker.
In GnuTLS the signatures are checked from first to last certificate, there is no limit on size of keys and no limit on length of certificate chain.
Stefano Di Paola discovered an issue with PHP that could allow someone to upload a file to any directory writeable by the httpd process. Any sanitizing performed on the prepended directory path is ignored. This bug can only be triggered if the $_FILES element name contains an underscore.
Stefano Di Paola reports:
Bad array parsing in php_variables.c could lead to show arbitrary memory content such as pieces of php code and other data. This affects all GET, POST or COOKIES variables.
In a Bugtraq posting, infamous41md(at)hotpop.com reported:
there are at least 5 exploitable buffer and heap overflows in the image handling code. this allows someone to craft a malicious image, trick a user into viewing the file in xv, and upon viewing that image execute arbitrary code under privileges of the user viewing image. note the AT LEAST part of the above sentence. there is such a plethora of bad code that I just stopped reading after a while. there are at least 100 calls to sprintf() and strcpy() with no regards for bounds of buffers. 95% of these deal with program arguments or filenames, so they are of no interest to exploit. however I just got sick of reading this code after not too long. so im sure there are still other overflows in the image handling code for other image types.
The posting also included an exploit.
David Watson reports a symlink vulnerability in getmail. If run as root (not the recommended mode of operation), a local user may be able to cause getmail to write files in arbitrary directories via a symlink attack on subdirectories of the maildir.
The syscons CONS_SCRSHOT ioctl(2) does insufficient validation of its input arguments. In particular, negative coordinates or large coordinates may cause unexpected behavior.
It may be possible to cause the CONS_SCRSHOT ioctl to return portions of kernel memory. Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way. For example, a terminal buffer might include a user-entered password.
This bug may be exploitable by users who have access to the physical console or can otherwise open a /dev/ttyv* device node.
Thomas Walpuski noted when OpenSSL would detect an error condition for a peer certificate, racoon mistakenly ignored the error. This could allow five invalid certificate states to properly be used for authentication.
Fix bug that might cause IP-based access control rules not to be interpreted correctly on 64-bit platforms.
Several scripting vulnerabilities were discovered and corrected in Mozilla:
javascript; links dragged onto another frame or page allows an attacker to steal or modify sensitive information from other sites. The user could be convinced to drag obscurred links in the context of a game or even a fake scrollbar. If the user could be convinced to drag two links in sequence into a separate window (not frame) the attacker would be able to run arbitrary programs.
Untrusted javascript code can read and write to the clipboard, stealing any sensitive data the user might have copied. Workaround: disable javascript
Signed scripts requesting enhanced abilities could construct the request in a way that led to a confusing grant dialog, possibly fooling the user into thinking the privilege requested was inconsequential while actually obtaining explicit permission to run and install software. Workaround: Never grant enhanced abilities of any kind to untrusted web pages.
According to the Mozilla project:
An attacker who could lure users into clicking in particular places, or typing specific text, could cause a security permission or software installation dialog to pop up under the user's mouse click, clicking on the grant (or install) button.
When processing URIs that contain an unqualified host name-- specifically, a domain name of only one component-- Mozilla will perform matching against the first component of the domain name in SSL certificates. In other words, in some situations, a certificate issued to "www.example.com" will be accepted as matching "www".
According to a Samba Team security notice:
A security vulnerability has been located in Samba 2.2.x <= 2.2.11 and Samba 3.0.x <= 3.0.5. A remote attacker may be able to gain access to files which exist outside of the share's defined path. Such files must still be readable by the account used for the connection.
The original notice for CAN-2004-0815 indicated that Samba 3.0.x <= 3.0.5 was vulnerable to the security issue. After further research, Samba developers have confirmed that only Samba 3.0.2a and earlier releases contain the exploitable code.
Gael Delalleau discovered several integer overflows in Mozilla's BMP decoder that can result in denial-of-service or arbitrary code execution.
Georgi Guninski discovered a stack buffer overflow which may be triggered when viewing email messages with vCard attachments.
Several heap buffer overflows were discovered and fixed in the most recent versions of Mozilla, Firefox, and Thunderbird. These overflows may occur when:
Each of these vulnerabilities may be exploited for remote code execution.
Stefan Esser of e-matters discovered that PHP's strip_tags() function would ignore certain characters during parsing of tags, allowing these tags to pass through. Select browsers could then parse these tags, possibly allowing cross-site scripting attacks.
Stefan Esser of e-matters discovered a condition within PHP that may lead to remote execution of arbitrary code. The memory_limit facility is used to notify functions when memory contraints have been met. Under certain conditions, the entry into this facility is able to interrupt functions such as zend_hash_init() at locations not suitable for interruption. The result would leave these functions in a vulnerable state.
An attacker that is able to trigger the memory_limit abort within zend_hash_init() and is additionally able to control the heap before the HashTable itself is allocated, is able to supply his own HashTable destructor pointer. [...]
All mentioned places outside of the extensions are quite easy to exploit, because the memory allocation up to those places is deterministic and quite static throughout different PHP versions. [...]
Because the exploit itself consist of supplying an arbitrary destructor pointer this bug is exploitable on any platform.
In some situations, subversion metadata may be unexpectedly disclosed via WebDAV. A subversion advisory states:
mod_authz_svn, the Apache httpd module which does path-based authorization on Subversion repositories, is not correctly protecting all metadata on unreadable paths.
This security issue is not about revealing the contents of protected files: it only reveals metadata about protected areas such as paths and log messages. This may or may not be important to your organization, depending on how you're using path-based authorization, and the sensitivity of the metadata.
Source code reviews of lha by Lukasz Wojtow, Thomas Biege, and others uncovered a number of vulnerabilities affecting lha:
There is a buffer overflow in the prepared statements API (libmysqlclient) when a statement containing thousands of placeholders is executed.
Under certain situations it is possible for the security icon which Mozilla displays when connected to a site using SSL to be spoofed. This could be used to make so-called "phishing attacks" more difficult to detect.
When handling FTP URLs containing NULL bytes, Mozilla will interpret the file content as HTML. This may allow unexpected execution of Javascript when viewing plain text or other file types via FTP.
A malicious web page can cause an automated file upload from the victim's machine when viewed with Mozilla with Javascript enabled. This is due to a bug permitting default values for type="file" <input> elements in certain situations.
Under some situations, Mozilla will automatically import a certificate from an email message or web site. This behavior can be used as a denial-of-service attack: if the certificate has a distinguished name (DN) identical to one of the built-in Certificate Authorities (CAs), then Mozilla will no longer be able to certify sites with certificates issued from that CA.
rssh expands command line paramters before invoking chroot. This could result in the disclosure to the client of file names outside of the chroot directory. A posting by the rssh author explains:
The cause of the problem identified by Mr. McCaw is that rssh expanded command-line arguments prior to entering the chroot jail. This bug DOES NOT allow a user to access any of the files outside the jail, but can allow them to discover what files are in a directory which is outside the jail, if their credentials on the server would normally allow them read/execute access in the specified directory.
An iDEFENSE security advisory reports:
Remote exploitation of an input validation error in version 1.2 of GNU radiusd could allow a denial of service.
The vulnerability specifically exists within the asn_decode_string() function defined in snmplib/asn1.c. When a very large unsigned number is supplied, it is possible that an integer overflow will occur in the bounds-checking code. The daemon will then attempt to reference unallocated memory, resulting in an access violation that causes the process to terminate.
A new feature of sudo 1.6.8 called "sudoedit" (a safe editing facility) may allow users to read files to which they normally have no access.
A buffer overflow exists in mod_proxy which may allow an attacker to launch local DoS attacks and possibly execute arbitrary code.
A number of vulnerabilities were discovered in CVS by Stefan Esser, Sebastian Krahmer, and Derek Price.
Additionally, iDEFENSE reports an undocumented command-line flag used in debugging does not perform input validation on the given path names.
CVS servers ("cvs server" or :pserver: modes) are affected by these vulnerabilities. They vary in impact but include information disclosure (the iDEFENSE-reported bug), denial-of-service (CVE-2004-0414, CVE-2004-0416, CVE-2004-0417 and other bugs), or possibly arbitrary code execution (CVE-2004-0418). In very special situations where the attacker may somehow influence the contents of CVS configuration files in CVSROOT, additional attacks may be possible.
Chris Evans discovered several flaws in the gdk-pixbuf XPM image decoder:
Some of these flaws are believed to be exploitable.
Chris Evans discovered several vulnerabilities in the libXpm image decoder:
The X11R6.8.1 release announcement reads:
This version is purely a security release, addressing multiple integer and stack overflows in libXpm, the X Pixmap library; all known versions of X (both XFree86 and X.Org) are affected, so all users of X are strongly encouraged to upgrade.
If the CUPS server (cupsd) receives a zero-length UDP message, it will disable its print queue browser service.
The Apache Software Foundation Security Team discovered a programming error in the apr-util library function apr_uri_parse. When parsing IPv6 literal addresses, it is possible that a length is incorrectly calculated to be negative, and this value is passed to memcpy. This may result in an exploitable vulnerability on some platforms, including FreeBSD.
A malicious user with DAV write privileges can trigger a null pointer dereference in the Apache mod_dav module. This could cause the server to become unavailable.
SITIC discovered a vulnerability in Apache 2's handling of environmental variable settings in the httpd configuration files (the main `httpd.conf' and `.htaccess' files). According to a SITIC advisory:
The buffer overflow occurs when expanding ${ENVVAR} constructs in .htaccess or httpd.conf files. The function ap_resolve_env() in server/util.c copies data from environment variables to the character array tmp with strcat(3), leading to a buffer overflow.
The Webmin developers documented a security issue in the release notes for version 1.160:
Fixed a security hole in the maketemp.pl script, used to create the /tmp/.webmin directory at install time. If an un-trusted user creates this directory before Webmin is installed, he could create in it a symbolic link pointing to a critical file on the system, which would be overwritten when Webmin writes to the link filename.
Code found in nmbd and smbd may allow a remote attacker to effectively crash the nmbd server or use the smbd server to exhaust the system memory.
zen-parse discovered a heap buffer overflow in Mozilla's POP client implementation. A malicious POP server could exploit this vulnerability to cause Mozilla to execute arbitrary code.
zen-parse discovered and iDEFENSE reported an exploitable integer overflow in a scriptable Mozilla component `SOAPParameter':
Improper input validation to the SOAPParameter object constructor in Netscape and Mozilla allows execution of arbitrary code. The SOAPParameter object's constructor contains an integer overflow which allows controllable heap corruption. A web page can be constructed to leverage this into remote execution of arbitrary code.
OpenOffice creates a working directory in /tmp on startup, and uses this directory to temporarily store document content. However, the permissions of the created directory may allow other user on the system to read these files, potentially exposing information the user likely assumed was inaccessible.
The mpg123 software version 0.59r contains a buffer overflow vulnerability which may permit the execution of arbitrary code as the owner of the mpg123 process.
Marcus Meissner discovered that ImageMagick's BMP decoder would crash when loading the test BMP file created by Chris Evans for testing the previous Qt vulnerability.
A class of bugs affecting many web browsers in the same way was discovered. A Secunia advisory reports:
The problem is that the browsers don't check if a target frame belongs to a website containing a malicious link, which therefore doesn't prevent one browser window from loading content in a named frame in another window.
Successful exploitation allows a malicious website to load arbitrary content in an arbitrary frame in another browser window owned by e.g. a trusted site.
A KDE Security Advisory reports:
A malicious website could abuse Konqueror to insert its own frames into the page of an otherwise trusted website. As a result the user may unknowingly send confidential information intended for the trusted website to the malicious website.
Secunia has provided a demonstration of the vulnerability at http://secunia.com/multiple_browsers_frame_injection_vulnerability_test/.
Numerous errors in isakmpd's input packet validation lead to denial-of-service vulnerabilities. From the Rapid7 advisory:
The ISAKMP packet processing functions in OpenBSD's isakmpd daemon contain multiple payload handling flaws that allow a remote attacker to launch a denial of service attack against the daemon.
Carefully crafted ISAKMP packets will cause the isakmpd daemon to attempt out-of-bounds reads, exhaust available memory, or loop endlessly (consuming 100% of the CPU).
Marcus Meissner discovered that imlib's BMP decoder would crash when loading the test BMP file created by Chris Evans for testing the previous Qt vulnerability. It is believed that this bug could be exploited for arbitrary code execution.
An advisory published by the MIT Kerberos team says:
The MIT Kerberos 5 implementation's Key Distribution Center (KDC) program contains a double-free vulnerability that potentially allows a remote attacker to execute arbitrary code. Compromise of a KDC host compromises the security of the entire authentication realm served by the KDC. Additionally, double-free vulnerabilities exist in MIT Kerberos 5 library code, making client programs and application servers vulnerable.
Double-free vulnerabilities of this type are not believed to be exploitable for code execution on FreeBSD systems. However, the potential for other ill effects may exist.
An advisory published by the MIT Kerberos team says:
The ASN.1 decoder library in the MIT Kerberos 5 distribution is vulnerable to a denial-of-service attack causing an infinite loop in the decoder. The KDC is vulnerable to this attack.
An unauthenticated remote attacker can cause a KDC or application server to hang inside an infinite loop.
An attacker impersonating a legitimate KDC or application server may cause a client program to hang inside an infinite loop.
Marcus Meissner discovered that imlib2's BMP decoder would crash when loading the test BMP file created by Chris Evans for testing the previous Qt vulnerability. There appears to be both a stack-based and a heap-based buffer overflow that are believed to be exploitable for arbitrary code execution.
According to the SpamAssassin 2.64 release announcement:
Security fix prevents a denial of service attack open to certain malformed messages; this DoS affects all SpamAssassin 2.5x and 2.6x versions to date.
The issue appears to be triggered by overly long message headers.
lukemftpd(8) is an enhanced BSD FTP server produced within the NetBSD project. The sources for lukemftpd are shipped with some versions of FreeBSD, however it is not built or installed by default. The build system option WANT_LUKEMFTPD must be set to build and install lukemftpd. [NOTE: An exception is FreeBSD 4.7-RELEASE, wherein lukemftpd was installed, but not enabled, by default.]
Przemyslaw Frasunek discovered several vulnerabilities in lukemftpd arising from races in the out-of-band signal handling code used to implement the ABOR command. As a result of these races, the internal state of the FTP server may be manipulated in unexpected ways.
A remote attacker may be able to cause FTP commands to be executed with the privileges of the running lukemftpd process. This may be a low-privilege `ftp' user if the `-r' command line option is specified, or it may be superuser privileges if `-r' is *not* specified.
By submitting a carefully crafted authentication packet, it is possible for an attacker to bypass password authentication in MySQL 4.1. Using a similar method, a stack buffer used in the authentication mechanism can be overflowed.
According to a Debian Security Advisory:
Andres Salomon noticed a problem in the CGI session management of Ruby, an object-oriented scripting language. CGI::Session's FileStore (and presumably PStore [...]) implementations store session information insecurely. They simply create files, ignoring permission issues. This can lead an attacker who has also shell access to the webserver to take over a session.
ISS X-Force reports that a remotely exploitable buffer overflow exists in the Netscape Security Services (NSS) library's implementation of SSLv2. From their advisory:
The NSS library contains a flaw in SSLv2 record parsing that may lead to remote compromise. When parsing the first record in an SSLv2 negotiation, the client hello message, the server fails to validate the length of a record field. As a result, it is possible for an attacker to trigger a heap-based overflow of arbitrary length.
Note that the vulnerable NSS library is also present in Mozilla-based browsers. However, it is not believed that browsers are affected, as the vulnerability is present only in code used by SSLv2 *servers*.
ripMIME may prematurely terminate decoding Base64 encoded messages when it encounters multiple blank lines or other non-standard Base64 constructs. Virus scanning and content filtering tools that use ripMIME may therefore be bypassed.
The ripMIME CHANGELOG file says:
There's viruses going around exploiting the ability to hide the majority of their data in an attachment by using blank lines and other tricks to make scanning systems prematurely terminate their base64 decoding.
The moinmoin package contains two bugs with ACLs and anonymous users. Both bugs may permit anonymous users to gain access to administrative functions; for example the delete function.
There is no known workaround, the vulnerability exists regardless if a site is using ACLs or not.
An rsync security advisory reports:
There is a path-sanitizing bug that affects daemon mode in all recent rsync versions (including 2.6.2) but only if chroot is disabled.
The bug may allow a remote user to access files outside of an rsync module's configured path with the privileges configured for that module.
Alexander Larsson reports that some versions of gnome-vfs and MidnightCommander contain a number of `extfs' scripts that do not properly validate user input. If an attacker can cause her victim to process a specially-crafted URI, arbitrary commands can be executed with the privileges of the victim.
Ulf Härnhammar discovered a pair of buffer overflows in the WAV file handling code of SoX. If an attacker can cause her victim to process a specially-crafted WAV file with SoX (e.g. through social engineering or through some other program that relies on SoX), arbitrary code can be executed with the privileges of the victim.
According to a KDE Security Advisory:
WESTPOINT internet reconnaissance services alerted the KDE security team that the KDE web browser Konqueror allows websites to set cookies for certain country specific secondary top level domains.
Web sites operating under the affected domains can set HTTP cookies in such a way that the Konqueror web browser will send them to all other web sites operating under the same domain. A malicious website can use this as part of a session fixation attack. See e.g. http://www.acros.si/papers/session_fixation.pdf
Affected are all country specific secondary top level domains that use more than 2 characters in the secondary part of the domain name and that use a secondary part other than com, net, mil, org, gov, edu or int. Examples of affected domains are .ltd.uk, .plc.uk and .firm.in
It should be noted that popular domains such as .co.uk, .co.in and .com are NOT affected.
Neils Heinen reports that the setuid `news' binaries installed as part of fidogate may be used to create files or append to file with the privileges of the `news' user by setting the LOGFILE environmental variable.
The log functions in jftpgw may allow remotely authenticated user to execute arbitrary code via the format string specifiers in certain syslog messages.
Qt contains several vulnerabilities related to image loading, including possible crashes when loading corrupt GIF, BMP, or JPEG images. Most seriously, Chris Evans reports that the BMP crash is actually due to a heap buffer overflow. It is believed that an attacker may be able to construct a BMP image that could cause a Qt-using application to execute arbitrary code when it is loaded.
An iDEFENSE security advisory describes a format string vulnerability that could be exploited when Courier-IMAP is run in debug mode (DEBUG_LOGIN set).
According to Christian Hammers:
[mysqlhotcopy created] temporary files in /tmp which had predictable filenames and such could be used for a tempfile run attack.
Jeroen van Wolffelaar is credited with discovering the issue.
Evgeny Demidov discovered that the Samba server has a buffer overflow in the Samba Web Administration Tool (SWAT) on decoding Base64 data during HTTP Basic Authentication. Versions 3.0.2 through 3.0.4 are affected.
Another buffer overflow bug has been found in the code used to support the "mangling method = hash" smb.conf option. The default setting for this parameter is "mangling method = hash2" and therefore not vulnerable. Versions between 2.2.0 through 2.2.9 and 3.0.0 through 3.0.4 are affected.
The Mozilla project's family of browsers contain a design flaw that can allow a website to spoof almost perfectly any part of the Mozilla user interface, including spoofing web sites for phishing or internal elements such as the "Master Password" dialog box. This achieved by manipulating "chrome" through remote XUL content. Recent versions of Mozilla have been fixed to not allow untrusted documents to utilize "chrome" in this way.
Chris Evans has discovered multiple vulnerabilities in libpng, which can be exploited by malicious people to compromise a vulnerable system or cause a DoS (Denial of Service).
According to a KDE Security Advisory, KDE may sometimes create temporary files without properly checking the ownership and type of the target path. This could allow a local attacker to cause KDE applications to overwrite arbitrary files.
Sebastian Krahmer discovered several remotely exploitable buffer overflow vulnerabilities in the MSN component of gaim.
In two places in the MSN protocol plugins (object.c and slp.c), strncpy was used incorrectly; the size of the array was not checked before copying to it. Both bugs affect MSN's MSNSLP protocol, which is peer-to-peer, so this could potentially be easy to exploit.
An iDEFENSE security advisory reports:
Remote exploitation of an input validation error in the uudecoding feature of Adobe Acrobat Reader (Unix) 5.0 allows an attacker to execute arbitrary code.
The Unix and Linux versions of Adobe Acrobat Reader 5.0 automatically attempt to convert uuencoded documents back into their original format. The vulnerability specifically exists in the failure of Acrobat Reader to check for the backtick shell metacharacter in the filename before executing a command with a shell. This allows a maliciously constructed filename to execute arbitrary programs.
John Graham-Cumming reports that certain configurations of POPFile may allow the retrieval of any files with the extensions .gif, .png, .ico, .css, as well as some files with the extension .html.
A buffer overflow exists in the logging functionality of the DHCP daemon which could lead to Denial of Service attacks and has the potential to allow attackers to execute arbitrary code.
Steve Grubb reports a buffer read overrun in libpng's png_format_buffer function. A specially constructed PNG image processed by an application using libpng may trigger the buffer read overrun and possibly result in an application crash.
Mozilla and Mozilla Firefox contains a flaw that may allow a malicious user to spoof SSL certification.
Glenn Randers-Pehrson has contributed a fix for the png vulnerabilities discovered by Chris Evans.
The Courier set of mail services use a common Unicode library. This library contains buffer overflows in the converters for two popular Japanese character encodings. These overflows may be remotely exploitable, triggered by a maliciously formatted email message that is later processed by one of the Courier mail services. From the release notes for the corrected versions of the Courier set of mail services:
iso2022jp.c: Converters became (upper-)compatible with ISO-2022-JP (RFC1468 / JIS X 0208:1997 Annex 2) and ISO-2022-JP-1 (RFC2237). Buffer overflow vulnerability (when Unicode character is out of BMP range) has been closed. Convert error handling was implemented.
shiftjis.c: Broken SHIFT_JIS converters has been fixed and became (upper-)compatible with Shifted Encoding Method (JIS X 0208:1997 Annex 1). Buffer overflow vulnerability (when Unicode character is out of BMP range) has been closed. Convert error handling was implemented.
Stefan Esser of e-matters Security discovered a baker's dozen of buffer overflows in Ethereal's decoders, including:
In addition, a vulnerability in the RADIUS decoder was found by Jonathan Heusser.
Finally, there is one uncredited vulnerability described by the Ethereal team as:
A zero-length Presentation protocol selector could make Ethereal crash.
Issues have been discovered in multiple protocol dissectors.
Issues have been discovered in multiple protocol dissectors.
SSLtelnet contains a format string vulnerability that could allow remote code execution and privilege escalation.
Roman Medina-Heigl Hernandez did a survey which other webmail systems where vulnerable to a bug he discovered in SquirrelMail. This advisory summarizes the results.
When pavuk sends a request to a web server and the server sends back the HTTP status code 305 (Use Proxy), pavuk copies data from the HTTP Location header in an unsafe manner. This leads to a stack-based buffer overflow with control over EIP.
Janek Vind "waraxe" reports that several issues in the PHPNuke software may be exploited via carefully crafted URL requests. These URLs will permit the injection of SQL code, cookie theft, and the readability of the PHPNuke administrator account.
This vulnerability would allow remote user to inject PHP code to be executed by eval() function. This vulnerability is only exploitable if variable $cfg['LeftFrameLight'] is set to FALSE (in file config.inc.php).
GNATS 3.113.1 contains multiple buffer overflows, through which a local attacker could gain elevated privileges on the system.
A programming error in the handling of some Linux system calls may result in memory locations being accessed without proper validation.
It may be possible for a local attacker to read and/or overwrite portions of kernel memory, resulting in disclosure of sensitive information or potential privilege escalation. A local attacker can cause a system panic.
giFT-FastTrack is susceptible to a remote Denial of Service attack which could allow a remote attacker to render HTTP services unusable. According to the developers, no code execution is possible; however, they recommend an immediate upgrade.
When the IPv6 code was added to xdm a critical test to disable xdmcp was accidentally removed. This caused xdm to create the chooser socket regardless if DisplayManager.requestPort was disabled in xdm-config or not.
A serious flaw exists in the MoinMoin software which may allow a malicious user to gain access to unauthorized privileges.
In December 2002, Timo Sirainen reported:
Cyrus IMAP server has a remotely exploitable pre-login buffer overflow. [...] Note that you don't have to log in before exploiting this, and since Cyrus runs everything under one UID, it's possible to read every user's mail in the system.
It is unknown whether this vulnerability is exploitable for code execution on FreeBSD systems.
The Cyrus team reported multiple vulnerabilities in older versions of Cyrus IMSPd:
These releases correct a recently discovered buffer overflow vulnerability, as well as clean up a significant amount of buffer handling throughout the code.
A remotely exploitable heap buffer overflow vulnerability was found in MPlayer's URL decoding code. If an attacker can cause MPlayer to visit a specially crafted URL, arbitrary code execution with the privileges of the user running MPlayer may occur. A `visit' might be caused by social engineering, or a malicious web server could use HTTP redirects which MPlayer would then process.
Timo Sirainen reports multiple buffer overflows that may be triggered while parsing messages, as well as input validation errors that could result in disclosure of mailing list passwords.
These bugs were resolved in the August 2003 snapshot of ecartis.
When the directive "SecFilterScanPost" is enabled, the Apache 2.x version of ModSecurity is vulnerable to an off-by-one overflow
clamav will exit when a programming assertion is not met. A malformed uuencoded message can trigger this assertion, allowing an attacker to trivially crash clamd or other components of clamav.
Stefan Esser reports:
A vulnerability within a libneon date parsing function could cause a heap overflow which could lead to remote code execution, depending on the application using libneon.
The vulnerability is in the function ne_rfc1036_parse, which is in turn used by the function ne_httpdate_parse. Applications using either of these neon functions may be vulnerable.
Greuff reports that the neon WebDAV client library contains several format string bugs within error reporting code. A malicious server may exploit these bugs by sending specially crafted PROPFIND or PROPPATCH responses.
Although several applications include neon, such as cadaver and subversion, the FreeBSD Ports of these applications are not impacted. They are specifically configured to NOT use the included neon. Only packages listed as affected in this notice are believed to be impacted.
A flaw exists in Gallery versions previous to 1.4.3-pl1 and post 1.2 which may give an attacker the potential to log in under the "admin" account. Data outside of the gallery is unaffected and the attacker cannot modify any data other than the photos or photo albums.
Jakub Jelinek reports several security related bugs in Midnight Commander, including:
Remote exploitation of a buffer overflow vulnerability in the NTLM authentication helper routine of the Squid Web Proxy Cache could allow a remote attacker to execute arbitrary code. A remote attacker can compromise a target system if the Squid Proxy is configured to use the NTLM authentication helper. The attacker can send an overly long password to overflow the buffer and execute arbitrary code.
The NISCC and the OUSPG developed a test suite for the H.323 protocol. This test suite has uncovered vulnerabilities in several H.323 implementations with impacts ranging from denial-of-service to arbitrary code execution.
In the FreeBSD Ports Collection, `pwlib' is directly affected. Other applications such as `asterisk' and `openh323' incorporate `pwlib' statically and so are also independently affected.
A programming error resulting in a failure to verify that an attempt to manipulate routing tables originated from a non-jailed process.
Jailed processes running with superuser privileges could modify host routing tables. This could result in a variety of consequences including packets being sent via an incorrect network interface and packets being discarded entirely.
Programming errors in the implementation of the msync(2) system call involving the MS_INVALIDATE operation lead to cache consistency problems between the virtual memory system and on-disk contents.
In some situations, a user with read access to a file may be able to prevent changes to that file from being committed to disk.
The leafnode NNTP server may go into an unterminated loop with 100% CPU use when an article is requested by Message-ID that has been crossposted to several news groups when one of the group names is the prefix of another group name that the article was cross-posted to. Found by Jan Knutar.
Fetchnews could hang when a news article to be downloaded lacked one of the mandatory headers. Found by Joshua Crawford.
When a downloaded news article ends prematurely, i. e. when the server sends [CR]LF.[CR]LF before sending a blank line, fetchnews may wait indefinitely for data that never arrives. Workaround: configure "minlines=1" (or use a bigger value) in the configuration file. Found by Toni Viemerö.
Shaun Colley reports that the script `mysqlbug' included with MySQL sometimes creates temporary files in an unsafe manner. As a result, an attacker may create a symlink in /tmp so that if another user invokes `mysqlbug' and quits without making any changes, an arbitrary file may be overwritten with the bug report template.
Stefan Esser reports:
Subversion versions up to 1.0.2 are vulnerable to a date parsing vulnerability which can be abused to allow remote code execution on Subversion servers and therefore could lead to a repository compromise.
NOTE: This vulnerability is similar to the date parsing issue that affected neon. However, it is a different and distinct bug.
Due to a programming error in code used to parse data received from the client, malformed data can cause a heap buffer to overflow, allowing the client to overwrite arbitrary portions of the server's memory.
A malicious CVS client can exploit this to run arbitrary code on the server at the privilege level of the CVS server software.
Joe Orton reports a memory leak in Apache 2's mod_ssl. A remote attacker may issue HTTP requests on an HTTPS port, causing an error. Due to a bug in processing this condition, memory associated with the connection is not freed. Repeated requests can result in consuming all available memory resources, probably resulting in termination of the Apache process.
Karol Wiesek and Greg MacManus reported via iDEFENSE that the Opera web browser contains a flaw in the handling of certain URIs. When presented with these URIs, Opera would invoke external commands to process them after some validation. However, if the hostname component of a URI begins with a `-', it may be treated as an option by an external command. This could have undesirable side-effects, from denial-of-service to code execution. The impact is very dependent on local configuration.
After the iDEFENSE advisory was published, the KDE team discovered similar problems in KDE's URI handlers.
The Debian security team reported a pair of vulnerabilities in fsp:
A vulnerability was discovered in fsp, client utilities for File Service Protocol (FSP), whereby a remote user could both escape from the FSP root directory (CAN-2003-1022), and also overflow a fixed-length buffer to execute arbitrary code (CAN-2004-0011).
Jindrich Makovicka reports a regression in proftpd's handling of IP address access control lists (IP ACLs). Due to this regression, some IP ACLs are treated as ``allow all''.
Some scripts installed with xine create temporary files insecurely. It is recommended that these scripts (xine-check, xine-bugreport) not be used. They are not needed for normal operation.
A remote exploitable buffer overflow has been discovered in exim when verify = header_syntax is used in the configuration file. This does not affect the default configuration.
The includes/sessions.php unnecessarily adds session item into session table and therefore vulnerable to a denial-of-service attack.
An input validation error was discovered in the kadmind code that handles the framing of Kerberos 4 compatibility administration requests. The code assumed that the length given in the framing was always two or more bytes. Smaller lengths will cause kadmind to read an arbitrary amount of data into a minimally-sized buffer on the heap.
A remote attacker may send a specially formatted message to kadmind, causing it to crash or possibly resulting in arbitrary code execution.
The kadmind daemon is part of Kerberos 5 support. However, this bug will only be present if kadmind was built with additional Kerberos 4 support. Thus, only systems that have *both* Heimdal Kerberos 5 and Kerberos 4 installed might be affected.
NOTE: On FreeBSD 4 systems, `kadmind' may be installed as `k5admind'.
Two programming errors were discovered in which path names handled by CVS were not properly validated. In one case, the CVS client accepts absolute path names from the server when determining which files to update. In another case, the CVS server accepts relative path names from the client when determining which files to transmit, including those containing references to parent directories (`../').
These programming errors generally only have a security impact when dealing with remote CVS repositories.
A malicious CVS server may cause a CVS client to overwrite arbitrary files on the client's system.
A CVS client may request RCS files from a remote system other than those in the repository specified by $CVSROOT. These RCS files need not be part of any CVS repository themselves.
The kernel interface for creating a snapshot of a filesystem is the same as that for changing the flags on that filesystem. Due to an oversight, the mksnap_ffs(8) command called that interface with only the snapshot flag set, causing all other flags to be reset to the default value.
A regularly scheduled backup of a live filesystem, or any other process that uses the mksnap_ffs command (for instance, to provide a rough undelete functionality on a file server), will clear any flags in effect on the filesystem being snapshot. Possible consequences depend on local usage, but can include disabling extended access control lists or enabling the use of setuid executables stored on an untrusted filesystem.
The mksnap_ffs command is normally only available to the superuser and members of the `operator' group. There is therefore no risk of a user gaining elevated privileges directly through use of the mksnap_ffs command unless it has been intentionally made available to unprivileged users.
A programming error in the shmat(2) system call can result in a shared memory segment's reference count being erroneously incremented.
It may be possible to cause a shared memory segment to reference unallocated kernel memory, but remain valid. This could allow a local attacker to gain read or write access to a portion of kernel memory, resulting in sensitive information disclosure, bypass of access control mechanisms, or privilege escalation.
A programming error has been found in the jail_attach(2) system call which affects the way that system call verifies the privilege level of the calling process. Instead of failing immediately if the calling process was already jailed, the jail_attach system call would fail only after changing the calling process's root directory.
A process with superuser privileges inside a jail could change its root directory to that of a different jail, and thus gain full read and write access to files and directories within the target jail.
FreeBSD does not limit the number of TCP segments that may be held in a reassembly queue. A remote attacker may conduct a low-bandwidth denial-of-service attack against a machine providing services based on TCP (there are many such services, including HTTP, SMTP, and FTP). By sending many out-of-sequence TCP segments, the attacker can cause the target machine to consume all available memory buffers (``mbufs''), likely leading to a system crash.
From the FreeBSD Security Advisory:
A programming error in the handling of some IPv6 socket options within the setsockopt(2) system call may result in memory locations being accessed without proper validation.
It may be possible for a local attacker to read portions of kernel memory, resulting in disclosure of sensitive information. A local attacker can cause a system panic.
A remote attacker could cause an application using OpenSSL to crash by performing a specially crafted SSL/TLS handshake.
A programming error in BIND 8 named can result in a DNS message being incorrectly cached as a negative response. As a result, an attacker may arrange for malicious DNS messages to be delivered to a target name server, and cause that name server to cache a negative response for some target domain name. The name server would thereafter respond negatively to legitimate queries for that domain name, resulting in a denial-of-service for applications that require DNS.
Heimdal does not correctly validate the `transited' field of Kerberos tickets when computing the authentication path. This could allow a rogue KDC with which cross-realm relationships have been established to impersonate any KDC in the authentication path.
Ulf Härnhammar discovered several vulnerabilities in LHa for UNIX's path name handling code. Specially constructed archive files may cause LHa to overwrite files or execute arbitrary code with the privileges of the user invoking LHa. This could be particularly harmful for automated systems that might handle archives such as virus scanning processes.
A straightforward stack buffer overflow exists in XChat's Socks5 proxy support.
The XChat developers report that `tsifra' discovered this issue.
NOTE: XChat Socks5 support is disabled by support in the FreeBSD Ports Collection.
When running rsync in daemon mode, no checks were made to prevent clients from writing outside of a module's `path' setting.
From the xinehq advisory:
By opening a malicious MRL in any xine-lib based media player, an attacker can write arbitrary content to an arbitrary file, only restricted by the permissions of the user running the application.
The flaw is a result of a feature that allows MRLs (media resource locator URIs) to specify arbitrary configuration options.
An unknown remotely exploitable vulnerability was disclosed. Robert Segall writes:
a security vulnerability was brought to my attention (many thanks to Akira Higuchi). Everyone running any previous version should upgrade to 1.6 immediately - the vulnerability may allow a remote exploit. No exploits are currently known and none have been observed in the wild till now. The danger is minimised if you run Pound in a root jail and/or you run Pound as non-root user.
The common.php script always trusts the `X-Forwarded-For' header in the client's HTTP request. A remote user could forge this header in order to bypass any IP address access control lists (ACLs).
Jack of RaptureSecurity reported a double byte buffer overflow in ident2. The bug may allow a remote attacker to execute arbitrary code within the context of the ident2 daemon. The daemon typically runs as user-ID `nobody', but with group-ID `wheel'.
A buffer overflow is present in some versions of the KDE personal information manager (kdepim) which may be triggered when processing a specially crafted VCF file.
When racoon receives an ISAKMP header, it will attempt to allocate sufficient memory for the entire ISAKMP message according to the header's length field. If an attacker crafts an ISAKMP header with a ridiculously large value in the length field, racoon may exceed operating system resource limits and be terminated, resulting in a denial of service.
When racoon receives an IKE message with an incorrectly constructed Generic Payload Header, it may behave erratically, going into a tight loop and dropping connections.
Chad Loder has discovered vulnerabilities in tcpdump's ISAKMP protocol handler. During an audit to repair these issues, Bill Fenner discovered some related problems.
These vulnerabilities may be used by an attacker to crash a running `tcpdump' process. They can only be triggered if the `-v' command line option is being used.
NOTE: the racoon ISAKMP/IKE daemon incorporates the ISAKMP protocol handler from tcpdump, and so is also affected by this issue.
Midnight Commander uses a fixed sized stack buffer while resolving symbolic links within file archives (tar or cpio). If an attacker can cause a user to process a specially crafted file archive with Midnight Commander, the attacker may be able to obtain the privileges of the target user.
Ralf Spenneberg discovered a serious flaw in racoon. When using Phase 1 main or aggressive mode, racoon does not verify the client's RSA signature. Any installations using X.509 authentication are strongly urged to upgrade.
Installations using pre-shared keys are believed to be unaffected.
Stefan Esser of e-matters found almost a dozen remotely exploitable vulnerabilities in Gaim. From the e-matters advisory:
While developing a custom add-on, an integer overflow in the handling of AIM DirectIM packets was revealed that could lead to a remote compromise of the IM client. After disclosing this bug to the vendor, they had to make a hurried release because of a change in the Yahoo connection procedure that rendered GAIM useless. Unfourtunately at the same time a closer look onto the sourcecode revealed 11 more vulnerabilities.
The 12 identified problems range from simple standard stack overflows, over heap overflows to an integer overflow that can be abused to cause a heap overflow. Due to the nature of instant messaging many of these bugs require man-in-the-middle attacks between client and server. But the underlying protocols are easy to implement and MIM attacks on ordinary TCP sessions is a fairly simple task.
In combination with the latest kernel vulnerabilities or the habit of users to work as root/administrator these bugs can result in remote root compromises.
Philippe Oechslin reported a denial-of-service vulnerability in oftpd. The oftpd server can be crashed by sending a PORT command containing an integer over 8 bits long (over 255).
From the Squid advisory:
Squid versions 2.5.STABLE4 and earlier contain a bug in the "%xx" URL decoding function. It may insert a NUL character into decoded URLs, which may allow users to bypass url_regex ACLs.
A remote attacker could cause zebra/quagga to crash by sending a malformed telnet command to their management port.
Users with admin rights can severly damage an phpBB installation, potentially triggered by viewing a page with a malicious link sent by an attacker.
A security hole exists that can be used to crash the proxy and execute arbitrary code. An exploit is circulating that takes advantage of this, and in some cases succeeds in obtaining a login shell on the machine.
A remote attacker may use specially crafted IKE/ISAKMP messages to cause racoon to delete security associations. This could result in denial-of-service or possibly cause sensitive traffic to be transmitted in plaintext, depending upon configuration.
Glenn Stewart reports a bug in wu-ftpd's ftpaccess `restricted-uid'/`restricted-gid' directives:
Users can get around the restriction to their home directory by issuing a simple chmod command on their home directory. On the next ftp log in, the user will have '/' as their root directory.
Matt Zimmerman discovered that the cause of the bug was a missing check for a restricted user within a code path that is executed only when a certain error is encountered.
Ulf Härnhammar discovered several vulnerabilities in GNU Anubis.
Ulf notes that these vulnerabilities can be exploited by a malicious IDENT server as a denial-of-service attack.
A number of buffer overflows were recently discovered in XFree86, prompted by initial discoveries by iDEFENSE. These buffer overflows are present in the font alias handling. An attacker with authenticated access to a running X server may exploit these vulnerabilities to obtain root privileges on the machine running the X server.
Steve Kemp reports (in a Debian bug submission):
Due to improper bounds checking it is possible for a malicious user to gain a shell with membership group 'games'. (The binary is installed setgid games).
Environmental variables are used without being bounds-checked in any way, from the source code:
highscore.c: /* Use the environment variable if it exists */ if ((str = getenv("XBOING_SCORE_FILE")) != NULL) strcpy(filename, str); else strcpy(filename, HIGH_SCORE_FILE); misc.c: if ((ptr = getenv("HOME")) != NULL) (void) strcpy(dest, ptr);Neither of these checks are boundschecked, and will allow arbitary shell code to be run.
Ulf Härnhammar reported four bugs in metamail: two are format string bugs and two are buffer overflows. The bugs are in SaveSquirrelFile(), PrintHeader(), and ShareThisHeader().
These vulnerabilities could be triggered by a maliciously formatted email message if `metamail' or `splitmail' is used to process it, possibly resulting in arbitrary code execution with the privileges of the user reading mail.
Ulf Härnhammar reports multiple buffer overflows in Emil, some of which are triggered during the parsing of attachment filenames. In addition, some format string bugs are present in the error reporting code.
Depending upon local configuration, these vulnerabilities may be exploited using specially crafted messages in order to execute arbitrary code running with the privileges of the user invoking Emil.
Anyone can get admin's username and password's md5 hash via a single web request. A working example is provided in the advisory.
The authors of UUDeview report repairing two buffer overflows in their software.
Henning Brauer discovered a programming error in Apache 1.3's mod_access that results in the netmasks in IP address access control rules being interpreted incorrectly on 64-bit, big-endian platforms. In some cases, this could cause a `deny from' IP address access control rule including a netmask to fail.
An attacker may cause Apache with mod_python to crash by using a specially constructed query string.
In 2003, two vulnerabilities were discovered in mpg123 that could result in remote code execution when using untrusted input or streaming from an untrusted server.
Dave Jones discovered a denial-of-service vulnerability in fetchmail. An email message containing a very long line could cause fetchmail to segfault due to missing NUL termination in transact.c.
Eric Raymond decided not to mention this issue in the release notes for fetchmail 6.2.5, but it was fixed there.
A malformed message could cause mailman to crash.
Dirk Mueller reports:
I've found a cross-site scripting vulnerability in the admin interface of mailman 2.1.3 that allows, under certain circumstances, for anyone to retrieve the (valid) session cookie.
From the 2.1.3 release notes:
Closed a cross-site scripting exploit in the create cgi script.
From the 2.1.1 release notes:
Closed a cross-site scripting vulnerability in the user options page.
Multiple researchers have discovered multiple SQL injection vulnerabilities in some versions of Php-Nuke. These vulnerabilities may lead to information disclosure, compromise of the Php-Nuke site, or compromise of the back-end database.
Ulf Härnhammar discovered an exploitable vulnerability in lbreakout2's environmental variable handling. In several instances, the contents of the HOME environmental variable are copied to a stack or global buffer without range checking. A local attacker may use this vulnerability to acquire group-ID `games' privileges.
An exploit for this vulnerability has been published by ``Li0n7 voila fr''.
Ulf Härnhammar discovered a format string bug in hsftp's file listing code may allow a malicious server to cause arbitrary code execution by the client.
An attacker can cause an assertion to trigger by sending a long User-Agent field in a request.
Yuuichi Teranishi reported a crash in libxml2's URI handling when a long URL is supplied. The implementation in nanohttp.c and nanoftp.c uses a 4K stack buffer, and longer URLs will overwrite the stack. This could result in denial-of-service or arbitrary code execution in applications using libxml2 to parse documents.
Lack of proper input validation in phpMyAdmin may allow an attacker to obtain the contents of any file on the target system that is readable by the web server.
Jedi/Sector One <j@pureftpd.org> reported the following on the full-disclosure list:
Every document is stored in multiple parts according to its sections (description, body, etc) in databases. And when the content has to be sent to the client, UdmDocToTextBuf() concatenates those parts together and skips metadata.
Unfortunately, that function lacks bounds checking and a buffer overflow can be triggered by indexing a large enough document.
'len' is fixed to 10K [in UdmDocToTextBuf] in searchd.c . S->val length depends on the length of the original document and on the indexer settings (the sample configuration file has low limits that work around the bug, though).
Exploitation should be easy, moreover textbuf points to the stack.
libtool attempts to create a temporary directory in which to write scratch files needed during processing. A malicious user may create a symlink and then manipulate the directory so as to write to files to which she normally has no permissions.
This has been reported as a ``symlink vulnerability'', although I do not think that is an accurate description.
This vulnerability could possibly be used on a multi-user system to gain elevated privileges, e.g. root builds some packages, and another user successfully exploits this vulnerability to write to a system file.
The seti@home client contains a buffer overflow in the HTTP response handler. A malicious, spoofed seti@home server can exploit this buffer overflow to cause remote code execution on the client. Exploit programs are widely available.
icecast 1.3.11 and earlier contained numerous security vulnerabilities, the most severe allowing a remote attacker to execute arbitrary code as root.
According to the author:
Fixed security loophole which allowed remote clients to access arbitrary files on our system.
The Chinese Console Environment contains exploitable buffer overflows.
Niels Heinen reports that ChiTeX installs set-user-id root executables that invoked system(3) without setting up the environment, trivially allowing local root compromise.
Kris Kennaway reports a remotely exploitable buffer overflow in newmail.c. Mike Silbersack submitted the fix.
An attacker may send an email message containing a specially constructed URL that will execute arbitrary commands when viewed.
An attacker may send a specially-formatted email message that will cause pine to crash.
Pine versions prior to 4.58 are affected by two vulnerabilities discovered by iDEFENSE, a buffer overflow in mailview.c and an integer overflow in strings.c. Both vulnerabilities can result in arbitrary code execution when processing a malicious message.
When rsync is run in server mode, a buffer overflow could allow a remote attacker to execute arbitrary code with the privileges of the rsync server. Anonymous rsync servers are at the highest risk.
From the Samba 3.0.2 release notes:
Security Announcement: It has been confirmed that previous versions of Samba 3.0 are susceptible to a password initialization bug that could grant an attacker unauthorized access to a user account created by the mksmbpasswd.sh shell script.
Mutt 1.4 contains a buffer overflow that could be exploited with a specially formed message, causing Mutt to crash or possibly execute arbitrary code.
From the Apache-SSL security advisory:
If configured with SSLVerifyClient set to 1 or 3 (client certificates optional) and SSLFakeBasicAuth, Apache-SSL 1.3.28+1.52 and all earlier versions would permit a client to use real basic authentication to forge a client certificate.
All the attacker needed is the "one-line DN" of a valid user, as used by faked basic auth in Apache-SSL, and the fixed password ("password" by default).
Jonathan Heusser discovered vulnerabilities in tcpdump's L2TP, ISAKMP, and RADIUS protocol handlers. These vulnerabilities may be used by an attacker to crash a running `tcpdump' process.
A small, fixed-size stack buffer is used to construct a filename based on a received control message. This could result in a stack buffer overflow.
A buffer overflow exists in the ProFTPD code that handles translation of newline characters during ASCII-mode file uploads. An attacker may exploit this buffer overflow by uploading a specially crafted file, resulting in code execution and ultimately a remote root compromise.
Any ElGamal sign+encrypt keys created by GnuPG contain a cryptographic weakness that may allow someone to obtain the private key. These keys should be considered unusable and should be revoked.
The following summary was written by Werner Koch, GnuPG author:
Phong Nguyen identified a severe bug in the way GnuPG creates and uses ElGamal keys for signing. This is a significant security failure which can lead to a compromise of almost all ElGamal keys used for signing. Note that this is a real world vulnerability which will reveal your private key within a few seconds.
...
Please take immediate action and revoke your ElGamal signing keys. Furthermore you should take whatever measures necessary to limit the damage done for signed or encrypted documents using that key.
Note that the standard keys as generated by GnuPG (DSA and ElGamal encryption) as well as RSA keys are NOT vulnerable. Note also that ElGamal signing keys cannot be generated without the use of a special flag to enable hidden options and even then overriding a warning message about this key type. See below for details on how to identify vulnerable keys.
Mathopd contains a buffer overflow in the prepare_reply() function that may be remotely exploitable.
A buffer overflow exists in lftp which may be triggered when requesting a directory listing from a malicious server over HTTP.
An authenticated user may trigger a format string vulnerability present in qpopper's UIDL code, resulting in arbitrary code execution with group ID `mail' privileges.
Fetchmail can be crashed by a malicious email message.
Applications utilizing pam_smb can be compromised by any user who can enter a password. In many cases, this is a remote root compromise.
libmcrypt does incomplete input validation, leading to several buffer overflows. Additionally, a memory leak is present. Both of these problems may be exploited in a denial-of-service attack.
The ChangeLog for phpBB 2.0.11 states:
Changes since 2.0.10

- Fixed unsetting global vars - Matt Kavanagh
- Fixed XSS vulnerability in username handling - AnthraX101
- Fixed not confirmed sql injection in username handling - warmth
- Added check for empty topic id in topic_review function
- Added visual confirmation mod to code base
Additionally, a US-CERT Technical Cyber Security Alert reports:
phpBB contains an user input validation problem with regard to the parsing of the URL. An intruder can deface a phpBB website, execute arbitrary commands, or gain administrative privileges on a compromised bulletin board.
The squid patches page notes:
This patch adds access controls to the cachemgr.cgi script, preventing it from being abused to reach other servers than allowed in a local configuration file.
The squid patches page notes:
Malicious users may spoof DNS lookups if the DNS client UDP port (random, assigned by OS as startup) is unfiltered and your network is not protected from IP spoofing.
There are 3 buffer overflows in jid.c that are triggered during parsing of JID strings when components (user, host or resource) are too long.
strcpy()
when "user" part is too long.strcpy()
when "host" part is too long.strcpy()
when "resource" part is too
long.These overflows can be used to perform a DoS attack on the server (sm process segfaults) and can possible be used for arbitrary code execution.
The squid patches page notes:
Squid may crash with the above error [FATAL: Incorrect scheme in auth header] when given certain request sentences.
Workaround: disable NTLM authentication.
If magic quotes are off there's a SQL injection when sending a forgotten password. It's possible to overwrite the admin password and to take over the whole system. In some files in the admin section there are some cross site scripting vulnerabilities. In the public frontend it's possible to include arbitrary php files.
