Description: Luigi Auriemma reported a buffer overflow vulnerability in the GameSpy SDK in the CD key validation. Games using the SDK may be affected.
It is reported that a remote user can send a specially crafted response to the target server. If the target server does not properly validate (limit) user-supplied input, then the remote user may be able to cause the target service to crash or potentially execute arbitary code. Depending on the game, the remote user may need to be authenticated to exploit this flaw.
A demonstration exploit for the Gore game (which uses the GameSpy SDK) is available at:

Impact: A remote user may be able to cause the target service to crash or potentially execute arbitary code. The specific impact depends on the application that implements the affected SDK function.
Solution: The vendor issued a fix on November 19, 2004. |
