Description:
Two vulnerabilities have been reported in the Quake3 Engine, which can be exploited by malicious people to access arbitrary files on a vulnerable system and potentially to compromise a user's system.
1) A boundary error exists within the handling of the "remapShader" command. This can be exploited to cause a buffer overflow via specially crafted "remapShader" commands sent to a client.
Successful exploitation may allow arbitrary code execution, but requires that the user is e.g. tricked into connecting to a malicious game server.
The vulnerability has been reported in the following software:
* Quake III Arena 1.32b.
* Return to Castle Wolfenstein 1.41.
* Wolfenstein: Enemy Territory 2.60.
Other versions may also be affected.
2) An input validation error exists within the processing of ".pk3" file download requests from a client. This can be to download arbitrary files accessible to the server process via directory traversal attacks.
The vulnerability has been reported in the following software:
* Quake III Arena / Team Arena
* Return to Castle Wolfenstein
* Wolfenstein: Enemy Territory
* Star Trek Voyager: Elite Force
Other versions may also be affected.
