+ <h1>Problem Description:</h1>
+ <p>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.</p>
+ <p>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.</p>
+ <h1>Impact:</h1>
+ <p>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.</p>
+ <p>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.</p>
+ <p>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.</p>
