DESCRIPTION:
Red Hat has issued an update for libcgroup. This fixes a weakness and
a vulnerability, which can be exploited by malicious, local users to
bypass certain security restrictions and gain escalated privileges.
The vulnerability is caused due to a boundary error in the
"parse_cgroup_spec()" function (src/tools/tools-common.c) and can be
exploited to cause a heap-based buffer overflow via a specially
crafted list of controllers.
NOTE: Additionally, a weakness exists in the cgrulesengd daemon when
handling NETLINK messages and can be exploited to put processes into
an existing control group allowing those tasks to run with more
resources (e.g. memory or CPU).
SOLUTION:
Updated packages are available via Red Hat Network.
