Call of Duty

Buffer overrun error
Most games based on the Quake 3 engine have this error on newer graphic cards. The buffer overrun happens when the game engine asks the graphic driver for a list of supported OpenGL extensions. The faulty game engine doesn’t allocate enough memory for the extension list

To fix it
Backup the executable. Open the executable in a hex editor (for example bless hex editor). Find the string GL_EXTENSIONS: %s and change it to GL_EXTENSIONS: %p.
