Patches Released for Critical Security Issues for Microsoft Windows

From Tom's Hardware: The critical vulnerability, according to Microsoft, is caused by the operating system’s improper handling of specifically crafted remote procedure call (RPC) requests. The problem is already being exploited in the wild and can allow attackers to gain full control of a computer. Microsoft also added that the windows firewall can be used to block such an attack.

Quoting a Microsoft security bulletin:

“It is possible that this vulnerability could be used in the crafting of a wormable exploit. Firewall best practices and standard default firewall configurations can help protect network resources from attacks that originate outside the enterprise perimeter.”

On older Windows operating systems, 2000, XP, and Server 2003, attackers can gain access to networks as anonymous users. They would still be able to access networks using the Vista and Server 2008 exploits, but they need to be an authenticated user.
