Synopsis
========
The Crossfire game server is vulnerable to a Denial of Service and
potentially to the execution of arbitrary code.
Background
==========
Crossfire is a cooperative multiplayer graphical adventure and
role-playing game. The Crossfire game server allows various compatible
clients to connect to participate in a cooperative game.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 games-server/crossfire-server < 1.9.0 >= 1.9.0
Description
===========
Luigi Auriemma discovered a vulnerability in the Crossfire game server,
in the handling of the "oldsocketmode" option when processing overly
large requests.
Impact
======
An attacker can set up a malicious Crossfire client that would send a
large request in "oldsocketmode", resulting in a Denial of Service on
the Crossfire server and potentially in the execution of arbitrary code
on the server with the rights of the game server.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Crossfire server users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=games-server/crossfire-server-1.9.0"
