Who is Vulnerable?
Vulnerability Description Microsoft DirectX is a software component which contains a set of APIs that provide access to graphics acceleration chips and sound cards and other types of media hardware. These APIs control low-level functions including graphics acceleration, support for input devices (such as joysticks, keyboards, and mice), and control of sound mixing and sound output. A buffer overflow vulnerability exists in Microsoft DirectX application framework. The vulnerability is due to the way DirectX handles specially crafted MJPEG streams. A remote attacker could exploit this vulnerability by persuading a user to open a specially crafted ASF or AVI file, potentially causing arbitrary code to be injected and executed in the security context of the logged in user. In case of an attack where code injection is not successful, the application utilizing the vulnerable DirectX library will terminate. In case of an attack where injection and execution is successful, the behavior of the target host is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the current user.
