Title: Microsoft Windows Media Services Handshake Sequence DoS Vulnerability
Severity: MODERATE
Description:
Misordered handshake sequences sent to a Windows Media Unicast Server via Windows Media Player will cause the server to crash. Restarting the Unicast Service, including any open sessions during the time of the crash, is required in order to regain normal functionality. This is due to the dependency of the application on successfully completing asychronous handshake requests in a proper sequential order between the client and the server.
