Severity:	high
Title:	Crossfire server: Denial of Service and potential arbitrary code execution
Date:	04/22/2006
Bugs:	#126169
ID:	200604-11

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	Architecture(s)
games-server/crossfire-server	< 1.9.0	>= 1.9.0	All supported architectures

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"
