1) Introduction
===============

2) Bugs
=======

------------------------------
A] cd-key hash buffer-overflow
------------------------------

The text field containing the client cd-key hash is the cause of a
buffer-overflow that affects the server.
Note: this is NOT the Gamespy cd-key SDK buffer-overflow.


--------------------------------
B] big nickname access violation
--------------------------------

If an attacker uses a too big nickname the server crashes for the
access to an arbitrary zone of the memory.
