http://secunia.com/advisories/37632/

DESCRIPTION:
Ubuntu has issued an update for grub2. This fixes a vulnerability
which can be exploited by malicious people with physical access to
conduct brute force attacks.

exploited to bypass authentication via brute force attacks using 1
character long passwords.
