%description
AFLNet is a greybox fuzzer for protocol implementations. Unlike existing
protocol fuzzers, it takes a mutational approach and uses state-feedback,
in addition to code-coverage feedback, to guide the fuzzing process. AFLNet
is seeded with a corpus of recorded message exchanges between the server and
an actual client. No protocol specification or message grammars are required.
It acts as a client and replays variations of the original sequence of
messages sent to the server and retains those variations that were effective
at increasing the coverage of the code or state space. To identify the server
states that are exercised by a message sequence, AFLNet uses the server’s
response codes. From this feedback, AFLNet identifies progressive regions in
the state space, and systematically steers towards such regions.
