2) Bug
======
Halo uses the Gamespy SDK and moreover the handshake algorithm provided
in this library (http://aluigi.altervista.org/papers/gssdkcr.h) to let
players to join servers.
The off-by-one bug is located just in the client's response (the last
stage of this handshake) because if it is longer than 32 bytes causes
the immediate crash of the server.
