SYMPTOMS
The Microsoft Windows Media Encoder formats digital content into a streamable format. If a malformed (bad) Media Streaming Broadcast Distribution (MSBD) request is sent to the Media Encoder, a malicious user can cause the service to fail. Although, this doesn't directly affect the Windows Media Server, it can interfere with any real-time broadcasts.
