tag_insight = "The GNOME Display Manager (GDM) provides the graphical login screen, shown
  shortly after boot up, log out, and when user-switching.

  A race condition flaw was found in the way GDM handled the cache
  directories used to store users' dmrc and face icon files. A local attacker
  could use this flaw to trick GDM into changing the ownership of an
  arbitrary file via a symbolic link attack, allowing them to escalate their
  privileges. (CVE-2011-0727)

  Red Hat would like to thank Sebastian Krahmer of the SuSE Security Team for
  reporting this issue.

  All users should upgrade to these updated packages, which contain a
  backported patch to correct this issue. GDM must be restarted for this
  update to take effect. Rebooting achieves this, but changing the runlevel
  from 5 to 3 and back to 5 also restarts GDM.";
