Severity: High Title: Unreal Tournament 2003/2004: Buffer overflow in 'secure' queries Date: July 19, 2004 Bugs: #54726 ID: 200407-14

Synopsis ========
Game servers based on the Unreal engine are vulnerable to remote code execution through malformed 'secure' queries.
Background ==========
Unreal Tournament 2003 and 2004 are popular first-person-shooter games. They are both based on the Unreal engine, and can be used in a game server / client setup.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 games-fps/ut2003 <= 2225-r2 >= 2225-r3 2 games-server/ut2003-ded <= 2225-r1 >= 2225-r2 3 games-fps/ut2004 < 3236 >= 3236 4 games-fps/ut2004-demo <= 3120-r3 >= 3120-r4 ------------------------------------------------------------------- 4 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
The Unreal-based game servers support a specific type of query called 'secure'. Part of the Gamespy protocol, this query is used to ask if the game server is able to calculate an exact response using a provided string. Luigi Auriemma found that sending a long 'secure' query triggers a buffer overflow in the game server.
Impact ======
By sending a malicious UDP-based 'secure' query, an attacker could execute arbitrary code on the game server.
Workaround ==========
Users can avoid this vulnerability by not using Unreal Tournament to host games as a server. All users running a server should upgrade to the latest versions.
Resolution ==========
All Unreal Tournament users should upgrade to the latest available versions:
# emerge sync
# emerge -pv ">=games-fps/ut2003-2225-r3" # emerge ">=games-fps/ut2003-2225-r3"
# emerge -pv ">=games-server/ut2003-ded-2225-r2" # emerge ">=games-server/ut2003-ded-2225-r2"
# emerge -pv ">=games-fps/ut2004-3236" # emerge ">=games-fps/ut2004-3236"
# emerge -pv ">=games-fps/ut2004-demo-3120-r4" # emerge ">=games-fps/ut2004-demo-3120-r4"
