DESCRIPTION:
IOActive has discovered a vulnerability in FreeBSD, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is cause due to a NULL pointer dereference error
when handling ASCONF chunks and can be exploited to cause a kernel
panic via a specially crafted verification tag sent in a SCTP
packet.

The vulnerability is confirmed in version 8.1. Other versions may
also be affected.

SOLUTION:
No official solution is currently available.

PROVIDED AND/OR DISCOVERED BY:
