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

ZDaemon is one of the most played multiplayer ports of the Doom engine
and at the same time one of the most criticized too.

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

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

The ZDaemon server is affected by a NULL pointer vulnerability which
allows an attacker to crash it when a specific type of command (type 6)
is used.

The attacker needs to join the server for exploiting this bug so his IP
address must be not banned and he must know the right keyword if the
server is protected with a password.
