CVE-2006-2236 Buffer overflow in the Quake 3 Engine, as used by (1) ET 2.60, (2) Return to Castle Wolfenstein 1.41, and (3) Quake III Arena 1.32b allows remote attackers to execute arbitrary commands via a long remapShader command. from Thilo Schulz in ioquake3 svn 765 git d21411452ef32b86c0b79ddcaf49221701dcdb07 Add string length checking to function COM_StripExtension. This fixes the R_RemapShader buffer overflow exploit that can be found here: http://milw0rm.com/exploits/1750
