Upgrade RHEL:6 libcgroup-pam to version 0:0.36.1-6.el6_0.1 or higher.
This issue was patched in RHSA-2011:0320.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcgroup-pam package and not the libcgroup-pam package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The cgre_receive_netlink_msg function in daemon/cgrulesengd.c in cgrulesengd in the Control Group Configuration Library (aka libcgroup or libcg) before 0.37.1 does not verify that netlink messages originated in the kernel, which allows local users to bypass intended resource restrictions via a crafted message.
