Flaw in Windows NT 4, 2000 and XP

A security bug in a network function of Windows NT 4, 2000 and XP can expose computers running those operating systems to a denial of service attack, Microsoft has warned.

The flaw lies in Microsoft's implementation of a protocol called RPC (Remote Procedure Call) that allows applications on a computer to call applications on another computer in a network. An attack on the RPC service could cause the networking services on the system to fail. More informtion can be found at http://www.microsoft.com/technet/security/bulletin/MS03-010.asp
