"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, 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."
