A buffer overflow vulnerability exists in the X360 VideoPlayer ActiveX control (VideoPlayer.ocx) version 2.6 when handling overly long arguments to the ConvertFile() method. An attacker can exploit this vulnerability by supplying crafted input to cause memory corruption and execute arbitrary code within the context of the current process.
