=====================================================================
Red Hat Security Advisory
Synopsis: Important: libcgroup security update
Advisory ID: RHSA-2011:0320-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0320.html
Issue date: 2011-03-03
CVE Names: CVE-2011-1006 CVE-2011-1022
=====================================================================
1. Summary:
Updated libcgroup packages that fix two security issues are now available
for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

3. Description:
The libcgroup packages provide tools and libraries to control and monitor
control groups.
A heap-based buffer overflow flaw was found in the way libcgroup converted
a list of user-provided controllers for a particular task into an array of
strings. A local attacker could use this flaw to escalate their privileges
via a specially-crafted list of controllers. (CVE-2011-1006)
It was discovered that libcgroup did not properly check the origin of
Netlink messages. A local attacker could use this flaw to send crafted
Netlink messages to the cgrulesengd daemon, causing it to put processes
into one or more existing control groups, based on the attacker's choosing,
possibly allowing the particular tasks to run with more resources (memory,
CPU, etc.) than originally intended. (CVE-2011-1022)
Red Hat would like to thank Nelson Elhage for reporting the CVE-2011-1006
issue.
All libcgroup users should upgrade to these updated packages, which contain
backported patches to correct these issues.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
