It is possible for a remote attacker to conduct a low-bandwidth
denial-of-service attack against a machine providing TCP-based services,
filling up the target's memory buffers and potentially leading to a system
crash. This vulnerability has been addressed on the FreeBSD 4.9-RELEASE
security fix branch. Security advisory FreeBSD-SA-04:04 contains more
details, as well as information on patching existing systems.
