Package: xscreensaver

Severity: grave
Tags: security
Justification: user security hole
Hi,
I'm a bit new to this bugreporting stuff. I have however discovered that it
is possible to kill xscreensaver with Alt+SysRq+F (if this function is not
disabled). This may comprimise security when xscreensaver-command is used
with the -lock option, because the screen will be unlocked.
gnome-screensaver seems not to be vulnerable to this attack.
