/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.

Wasn't there a thread where some /prog/rider did a test and found the cost of stripping comments is non-negligible for sufficiently large amounts of comments? How much more time is wasted by preprocessing? As they say in the FIOC community "programmer seconds are valuabler the computer seconds". How long are you willing to spend compiling before #ifdef bloat gets out of hand?
