A vulnerability has been reported in Call of Duty, Call of Duty United Offensive, and Call of Duty 2, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the "callvote map" command. This can be exploited to cause a buffer overflow by calling the command with a long "MAP" parameter (more than 64 bytes).
Successful exploitation may allow the execution of arbitrary code.
The vulnerability has been reported in:
Call of Duty version 1.5b
Call of Duty United Offensive version 1.51b
Call of Duty 2 version 1.3
Other versions may also be affected.
Solution: Restrict access to game servers to trusted people only.
