===============
1) Introduction
===============
Dredd vs Death is a cool FPS game based on the homonym comic strip.
The game has been developed by Rebellion (http://www.rebellion.co.uk)
and has been released in October 2003.

======
2) Bug
======
The problem is a format string bug in the handling of the messages
received from clients like "player connected", chat messages and so on.
Like any in-game bug, the attacker must have access to the match (so if
the server is protected by password, he must know it).
#######################################################################
===========
3) The Code
===========
Launch a client and a server, go on the client side, join the server
and send the following chat message (by default pressing the 'T' key):
%n%n%n%n%n
The server will crash immediately.
You can do the same check running only the server and sending the chat
message from the same computer.

======
4) Fix
======
No fix.
Developers have not replied to my mails.
