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

World in conflict is a RTS game developed by Massive Entertainment
(http://www.massive.se) and released about a month ago.

#######################################################################

======
2) Bug
======

The server is vulneable to a Denial of Service attack (crash) caused by
the access to a NULL pointer.
The problem happens in the GetMagicNumberString function which takes
the third byte of the data received from the client on the VOIP port
52999 and returns a text string if this value is valid ("ABC" for type
0, "DEF" for 1, "GHI" for 2 and so on) or NULL if it's invalid.
Then the string returned by this function is compared with another one
and here happens the NULL pointer access.

#######################################################################

===========
3) The Code
===========

Connect to the VOIP port of the server (default 52999) with telnet or
netcat and type something like aaaaaaa.
The server will crash immediately.

#######################################################################

======
4) Fix
======

Patch v1.001 (aka Update #001)
