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


Unreal Tournament III is currently the latest game (2007) of the Unreal
series created by Epic Games (http://www.epicgames.com).

2) Bug
======


The game implements a particular command called STEAMBLOB which is
handled in any case even if Steam is not running.

This command accepts three arguments that are C, N and B and just this
last one (doesn't matter what value it has) is the cause of a problem
during the handling of some pointers that are left unitialized.
The effect is the crash of the whole server due to the access to
invalid memory or a NULL pointer.

It's enough only one UDP packet to exploit the vulnerability so there
are no limitations.

3) The Code

unrealfp -x 2 -c "STEAMBLOB B=" SERVER PORT

4) Fix

No fix.
