/prog/ Challenge #1872 - Exploit slock

slock is a simple X display locker utility.

After invoking slock, the only way to get out of it is to enter your password.

The challenge: find a way to exploit it, so that the you get out of slock without knowing the victim's password.

The source code is less than 400 LOCs.

Good luck.

Gave me a kernel panic and I had to shutdown the computer.
Not an exploit unless it kills slock only and puts the attacker back at the X11 session or a logged in tty.
