Chris Moneymaker's World Poker Championship is a poker game developed
and published by Valusoft (http://www.valusoft.com) in April 2005.

2) Bug
======

The game is affected by a buffer-overflow during the usage of sprintf()
for the creation of the string "%s has joined the game." (where %s is
replaced by the nickname passed by the client) with a destination
buffer of 256 bytes.

The vendor has handled this security bug as a "normal" bug so no patch
is planned.
