This signature detects an attempt to exploit a known vulnerability against FreeBSD while processing certain packets. Successful exploitation could allow an attacker to perform Denial of Service attack.
FreeBSD 5.1 and earlier, and Mac OS X before 10.3.4, allows remote attackers to cause a denial of service (resource exhaustion of memory buffers and system crash) via a large number of out-of-sequence TCP packets, which prevents the operating system from creating new connections.
