FOSDEM

This talk will present zzuf's internals and give a few examples of real life bugs in various widespread end-user applications that zzuf is able to find automatically.

About Zzuf:

zzuf is a transparent application input fuzzer. Its purpose is to find bugs in applications by corrupting their user-contributed input. It works by intercepting file and network operations and changing random bits in the program's input. zzuf's behaviour is deterministic, making it easier to reproduce bugs.
