tag_insight = "X.Org is an open source implementation of the X Window System. It provides
  the basic low-level functionality that full-fledged graphical user
  interfaces are designed upon. These xorg-x11 packages also provide the
  X.Org libXfont runtime library.

  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 xorg-x11 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.";
