Microsoft Security Bulletin (MS00-097) - Microsoft has released a patch that eliminates a security vulnerability in Microsoft Windows Media Server which allows malicious users to degrade the performance of a Windows Media server to the point where it could no longer provide useful service. When a connection to a Windows Media server is made, then severed, using a particular sequence of TCP/IP packets, the Windows Media Unicast Service does not release all of the resources allocated to the connection. When repeatedly making and then severing connections in this manner, malicious users can exhaust the resources of the server. Microsoft FAQ on this issue available here.
