Discussion
Microsoft Windows Server Service is prone to a remote buffer-overflow vulnerability.
This vulnerability arises when the service processes a malicious message in RPC communications.
A successful attack may result in arbitrary code execution with SYSTEM privileges leading to a full compromise. Attack attempts may result in denial-of-service conditions as well.
Microsoft has reported that this issue is being exploited in the wild.
Update (August 14, 2006): A worm named 'W32.Wargbot' that exploits this issue to spread is currently in the wild.
