Hi, Locking the screen with xlock, then pressing ctrl+alt+numeric* unlocks the screen as described at: http://www.h-online.com/security/news/item/X-org-server-allows-anyone-to-unlock-computer-1417864.html
This happens on amd64 week-old-current, tried with both fvwm (from base) and with jwm window manager. I suppose if anyone has physical access to a machine, they could get access to hard drive with a boot cd, but this vulnerability makes it pretty easy. Brett.
