Who is Vulnerable?
Vulnerability Description Microsoft DirectX is a set of libraries that aim for accelerated video and audio experience on Microsoft Windows operating system. The three-dimension (3D) acceleration engine of DirectX is known as Direct3D. Direct3D include texture rendering, which displays bitmap images on the surface of 3D objects. The texture rendering can use many types of image formats, such as the Targa (TGA) format. A buffer overflow vulnerability exists in Microsoft DirectX application framework. The vulnerability is due to the way certain DirectX libraries handle specially crafted Targa (TGA) image files. A remote attacker could exploit this vulnerability by persuading a user to open a specially crafted TGA file, potentially causing arbitrary code to be injected and executed in the security context of the logged in user. In an attack case where code injection is not successful, the vulnerable application using the affected application will terminate immediately. In a more sophisticated attack where code injection is successful, the behavior of the target 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.
