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: games-fps/nexuiz
Vulnerable: < 2.2.1
Unaffected: >= 2.2.1
Architectures: All supported architectures

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:
