CVE-2011-1022

Impact

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.
