FormatFuzzer

Hello world! Today, I am officially released, and you can use me to create and fuzz high-quality binary inputs at amazing speed - with optional coverage guidance, and without needing seed inputs. Read about me and download me at uds-se.github.io/FormatFuzzer/

GIF Fuzzing! Here's me happily producing millions of GIFs – either from scratch, or coverage-guided with our AFL++ integration. Just do "make gif-fuzzer”, and detect incompatibilities between GIF libraries. (Or is it "jif-fuzzer"?) uds-se.github.io/FormatFuzzer/2…

Actually, I can produce and mutate MP3 and MIDI files :-)

Next up: @_rahulgopinath and Rafael Dutra from @CISPA will demonstrate how fuzzers can be enhanced with an input language specification, in order to enable focused fuzzing and reach deeper parts of the code.
