    gnome-screensaver vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.10
    
    Summary:
    
    gnome-screensaver would allow unintended access to the user session.
    
    Software Description:
    - gnome-screensaver: GNOME screen saver and locker
    
    Details:
    
    It was discovered that gnome-screensaver did not start automatically after
    logging in. This may result in the screen not being automatically locked
    after the inactivity timeout is reached, permitting an attacker with
    physical access to gain access to an unlocked session.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.10:
      gnome-screensaver               3.6.0-0ubuntu2.1
    
    After a standard system update you need to restart your session to make
    all the necessary changes.
