Quake 3 engine remapShader command buffer overflow
|quake3-remapshader-client-bo (26264)||High Risk|
Quake 3 is vulnerable to a buffer overflow, caused by improper bounds checking of the remapShader command. By sending a specially-crafted remapShader command, a remote attacker could overflow a buffer and execute arbitrary code on a Quake 3 client system, if the attacker could persuade a potential victim to connect to a malicious game server.
Note: This vulnerability affects any game that uses the Quake 3 Engine and the remapShader command.
