Description

OpenVZ has issued an update for kernel. This fixes a vulnerability, which can be exploited by 
malicious, local users to cause a DoS (Denial of Service) or potentially gain escalated privileges.

The vulnerability is caused due to an error within the "mountpoint_last()" function (fs/namei.c) 
and can be exploited to cause an out-of-memory or use-after-free condition.


Solution:
Update kernel branch RHEL6 to 042stab092.3.

Provided and/or discovered by:
Vasily Averin, Parallels.
