Bonjour,
une petite faille de sécurité ''amusante''
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=555195
GRUB accepts user input as valid password as long as user enters some first
characters of password correctly.
I.e. if /boot/grub/grub.cfg reads:
set superusers="user1"
password user1 password1
Then user can enter "p", "pa", "pas" etc, and GRUB will 'eat it' as correct
password.
Considering that this 'feature' effectively lowers password length to 1 (one),
I've set severity of this bug to 'important'. Feel free to add 'security' tag,
if appropriate.
