Executive brief
Microsoft Windows Media Foundation is a core multimedia processing component in Windows that handles audio and video playback. A heap buffer overflow vulnerability in this component allows an attacker on the network to execute arbitrary code on a system without authorization, potentially leading to complete system compromise and data theft.
Technical details
A heap-based buffer overflow exists in Microsoft Windows Media Foundation, a multimedia framework used for audio/video codec processing. The vulnerability allows remote code execution over the network without requiring authentication or user interaction. An attacker can send a specially crafted media file or stream that triggers the overflow, overwriting adjacent heap memory and enabling arbitrary code execution with the privileges of the user running the media application. Microsoft has published patches through the Security Update Guide.
