Bug 166044 – games-fps/nexuiz: input validation errors

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Markus Rothe (RETIRED) 2007-02-09 09:41:14 UTC]

Nexuiz >=2.2.1 fixes a security issue resulting is a DOS. 2.2.3 is already in the tree, but not stable.

from http://www.frsirt.com/english/advisories/2006/4992 :


- Technical Description

Multiple vulnerabilities have been identified in Nexuiz, which could be exploited by attackers to execute arbitrary commands or cause a denial of service.

The first issue is due to an input validation error within "clientcommands", which could be exploited by remote attackers to inject arbitrary commands.

The second issue is due to an error when processing player connections, which could be exploited by attackers to crash a vulnerable application or exhaust all available memory resources, creating a denial of service condition.


- Affected Products

Nexuiz versions prior to 2.2.1

I removed 2.1

[Comment 2 Markus Rothe (RETIRED) 2007-02-09 17:48:20 UTC]

wasn't 2.1 the latest stable version for x86 and amd64?

[Comment 3 Markus Rothe (RETIRED) 2007-02-09 17:51:11 UTC]

whoops, you marked 2.2.3 stable, too. cool. thanks.

@security: what's next? glsa, no glsa?

[Comment 4 Mr. Bones. (RETIRED) 2007-02-09 17:55:11 UTC]

I think since 2.1 was stable a glsa would be good.

Yes, good, you should join the security team :)
