  A buffer overflow flaw was found in the way the libXfont library, used by
  the X.Org server, handled malformed font files compressed using UNIX
  compress. A malicious, local user could exploit this issue to potentially
  execute arbitrary code with the privileges of the X.Org server.
  (CVE-2011-2895)

  Users of libXfont should upgrade to these updated packages, which contain a
  backported patch to resolve this issue. All running X.Org server instances
  must be restarted for the update to take effect.");
