Vigil@nce: GNOME, unlocking gnome-screensaver

February 2010 by Vigil@nce

A local attacker can plug a second screen, in order to stop
gnome-screensaver.

 Severity: 1/4
 Consequences: user access/rights
 Provenance: user console
 Means of attack: 1 attack
 Ability of attacker: technician (2/4)
 Confidence: confirmed by the editor (5/5)
 Diffusion of the vulnerable configuration: high (3/3)
 Creation date: 15/02/2010

IMPACTED PRODUCTS

 Unix - plateform

DESCRIPTION OF THE VULNERABILITY

The gnome-screensaver program locks the screen and displays a
drawing.

When a system is locked, an attacker can:
 plug a second screen
 wait for its autodetection, and wait for the password input
form to be displayed on this screen
 unplug the secondary screen
 press a few keyboard keys
The gnome-screensaver then tries to handle keys associated to a
non existing screen, which stops it.

A local attacker can therefore plug a second screen, in order to
stop gnome-screensaver, and to access to user’s session.
