There exists a denial of service vulnerability in the IDirectPlay4 application programming interface (API) of Microsoft DirectPlay, due to an insufficient input validation of incoming network data. In an attack case, where an attacker sends malformed DirectPlay packets, any applications using the component of DirectX (typically network capable games) can fail and has to be restarted to resume normal functionality. The attacked DirectPlay application on the target system will terminate with a memory access violation error upon receiving the malformed message.
