[GLSA-200407-14] Unreal Tournament 2003/2004: Buffer overflow in \'secure\' queries

Vulnerability Assessment Summary
Unreal Tournament 2003/2004: Buffer overflow in 'secure' queries

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200407-14
(Unreal Tournament 2003/2004: Buffer overflow in 'secure' queries)


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, a possible hacker 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.
