Severity:	normal
Title:	Nexuiz: Multiple vulnerabilities
Date:	02/25/2007
Bugs:	#166044
ID:	200702-09

Synopsis

Two separate vulnerabilities have been found in Nexuiz allowing the remote execution of arbitrary code and a Denial of Service.

Background

Nexuiz is a multi-player FPS game which uses a modified version of the Quake 1 engine.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
games-fps/nexuiz	< 2.2.1	>= 2.2.1	All supported architectures

Description

Nexuiz fails to correctly validate input within "clientcommands". There is also a failure to correctly handle connection attempts from remote hosts.

Impact

Using a specially crafted "clientcommand" a remote attacker can cause a buffer overflow in Nexuiz which could result in the execution of arbitrary code. Additionally, there is a Denial of Service vulnerability in Nexuiz allowing an attacker to cause Nexuiz to crash or to run out of resources by overloading it with specially crafted connection requests.

Workaround

There is no known workaround at this time.

Resolution

All Nexuiz users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=games-fps/nexuiz-2.2.1"
