Description:
Luigi Auriemma has reported a vulnerability in the Unreal Engine, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the processing of secure queries, which are used to verify that a queried server is a legit Unreal server. This can be exploited to cause a buffer overflow by sending an overly long challenge string to a vulnerable server.
Successful exploitation may allow execution of arbitrary code.
The following games are reportedly affected:
* DeusEx (build 1.112fm and prior)
* Devastation (build 390 and prior)
* Mobile Forces (build 20000 and prior)
* Nerf Arena Blast (build 1.2 and prior)
* Postal 2 (build 1337 and prior)
* Rune (build 107 and prior)
* Tactical Ops (build 3.4.0 and prior)
* TNN Pro Hunter
* Unreal 1 (build 226f and prior)
* Unreal II XMP (build 7710 and prior)
* Unreal Tournament (build 451b and prior)
* Unreal Tournament 2003 (build 2225 and prior)
* Unreal Tournament 2004 (prior to build 3236)
* Wheel of Time (build 333b and prior)
* X-com Enforcer
Solution:
The vulnerability has been addressed in Unreal Tournament 2004 (build 3236 and later).
Only play multi-player games on trusted, local networks.
