gdm vulnerability

Details

Marcus Meissner discovered a race condition in gdm’s handling of the
~/.ICEauthority file permissions. A local attacker could exploit this
to become the owner of an arbitrary file in the system. When getting
control over automatically executed scripts (like cron jobs), the
attacker could eventually leverage this flaw to execute arbitrary
commands with root privileges.
