Luigi Auriemma has reported a vulnerability in multiple games, 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 handling of secure Gamespy queries. This can be exploited to cause a buffer overflow by sending a specially crafted, overly long query to the server.
Successful exploitation may potentially allow execution of arbitrary code on the game server.
The vulnerability has been reported in the following products:
- Alien versus Predator 2, version 184.108.40.206.
- Blood 2, version 2.1.
- No one lives forever, version 1.004.
- Shogo, version 2.2.
Other versions may also be affected.
Solution: Grant only trusted clients access to matches on vulnerable game servers.
