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

Halo is the great FPS game developed by Bungie Studios and ported on PC
by Gearbox Software (http://www.gearboxsoftware.com).
Although it has been released at the end of 2003, it's still one of the
most played games with hundreds of internet servers.

2) Bug
======

This vulnerability is exactly like the old one I found over 3 years ago
in version 1.06 (haloloop) and which was fixed (or it's the case of
saying partially fixed) in version 1.07: an endless loop caused by a
malformed in-game packet which freezes completely the server.
