SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/36955/

DESCRIPTION:
Some vulnerabilities have been reported in FreeBSD, which can be
exploited by malicious, local users to cause a DoS (Denial of
Service) and potentially gain escalated privileges.

1) A use-after-free error caused by a race condition within the pipe
"close()" implementation related to kqueues can be exploited to e.g.
execute arbitrary code with kernel privileges.

2) A NULL pointer dereference error can be exploited to e.g. execute
arbitrary code with kernel privileges.

For more information:
SA36945

NOTE: Additionally, the vendor provides an enhancement against NULL
pointer exploits.

SOLUTION:
Update FreeBSD or apply patches.
