Buffer overflow in the UGameEngine::UpdateConnectingMessage function in the Unreal engine 1, 2, and 2.5, as used in multiple games including Unreal Tournament 2004, Unreal tournament 2003, Postal 2, Raven Shield, and SWAT4, when downloads are enabled, allows remote attackers to execute arbitrary code via a long LEVEL field in a WELCOME response to a download request.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
