<title>Unreal Tournament 2003/2004: Buffer overflow in 'secure' queries</title>
|

<synopsis>

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.

|
|
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 type="high">
|
|
<p>
|
|
By sending a malicious UDP-based 'secure' query, an attacker could execute
|
|
arbitrary code on the game server.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
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.

All Unreal Tournament users should upgrade to the latest available
|
|
versions:
