This signature detects attempts to exploit a known vulnerability against the GameSpy query protocol supported by Unreal game engine. Attackers can crash a game server running the Unreal game engine, or execute arbitrary code with permissions of the user running the server.
Unreal Engine is reportedly prone to a memory corruption vulnerability. This issue presents itself when a remote attacker sends an excessive value to a vulnerable game server through a '\secure\' query. An attacker can exploit this issue to potentially overwrite sensitive memory addresses leading to a variety of attacks including denial of service and possible remote code execution.
