Technical details

A heap-based buffer overflow in Windows Media allows an unauthenticated attacker to achieve remote code execution over the network. The vulnerability likely occurs during processing of malformed media files or streams, requiring user interaction (such as opening a crafted file or visiting a malicious website). Successful exploitation grants the attacker code execution with the privileges of the logged-in user.
