"A flaw was found in the way the gdm package was built. The gdm package
was missing TCP wrappers support on 64-bit platforms, which could
result in an administrator believing they had access restrictions
enabled when they did not. (CVE-2007-5079)

This update also fixes the following bug :

  - sometimes the system would hang instead of properly
    shutting down when a user chose 'Shut down' from the
    login screen. (BZ#625818)

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."
