wargames

ugh, /g/ has proven to be too incompetent and full of dilettantes to crack a crackme together, so I'm hoping /prog/ won't disappoint.

Here's a wargame, a hacking puzzle where you get from level to level using knowledge of programming and computers.

The only problem I see there is that %s is not checked for null-terminality, and thus if you send e. g. 64kB of 0x36 there is some chance that it will go on printing garbage from stack until it either crashes with SIGSEGV or (more likely) just stops printing if there was a single zero anywhere on the stack.

Not sageing because I'm curious if I'm a blind retard.
