[RT #21918] * Introduces a new tool "dnssec-verify" that validates a signed zone, checking for the correctness of signatures and NSEC/NSEC3 chains. [RT #23673] * BIND now recognizes the TLSA resource record type, created to support IETF DANE (DNS-based Authentication of Named Entities) [RT #28989] * The new "inline-signing" option, in combination with the "auto-dnssec" option that was introduced in BIND 9.7, allows named to sign zones completely transparently.

When set to "warn", checks SPF and TXT records in spf format, warning if either resource record type occurs without a corresponding record of the other resource record type. [RT #33355] Adds support for Uniform Resource Identifier (URI) resource records. [RT #23386] Adds support for the EUI48 and EUI64 RR types. [RT #33082] Adds support for the RFC 6742 ILNP record types (NID, LP, L32, and L64). [RT #31836] Feature Changes Changes timing of when slave zones send NOTIFY messages after loading a new copy of the zone. They now send the NOTIFY before writing the zone data to disk. This will result in quicker propagation of updates in multi-level server structures. [RT #27242] "named -V" can now report a source ID string. (This is will be of most interest to developers and troubleshooters). The source ID for ISC's production versions of BIND is defined in the "srcid" file in the build tree and is normally set to the most recent git hash. [RT #31494] Response Policy Zone performance enhancements. New "response-policy" option "min-ns-dots". "nsip" and "nsdname" now enabled by default with RPZ.

Approved by: delphij (mentor) MFC after: 3 days Security: CVE-2012-5688 Sponsored by: DK Hostmaster A/S 2012-09-20T04:12:09Z Doug Barton dougb@FreeBSD.org 2012-09-20T04:12:09Z urn:sha1:8888cf1ddc96d2c9d9fae50cd84da8e325999de0 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.

CVE: CVE-2012-3817 Posting date: 24 July, 2012 2012-06-04T22:11:20Z Doug Barton dougb@FreeBSD.org 2012-06-04T22:11:20Z urn:sha1:fe5cfeb46bdfc05b7e0a7e78d5de976f6a4e2df4 a critical bugfix: 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. All BIND users are strongly encouraged to upgrade. 2012-05-28T19:47:56Z Doug Barton dougb@FreeBSD.org 2012-05-28T19:47:56Z urn:sha1:687aeb3821cb3144a06fb18268c456be2af6e4a7 Feature Change * BIND now recognizes the TLSA resource record type, created to support IETF DANE (DNS-based Authentication of Named Entities) Bug Fix * The locking strategy around the handling of iterative queries has been tuned to reduce unnecessary contention in a multi- threaded environment.
