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.
