  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.");
