Microsoft warns of critical Windows flaw | CNET News.com: "'It should be emphasized that this vulnerability poses an enormous threat, and appropriate patches provided by Microsoft should be immediately applied,' the group said in an advisory posted to its Web site. The group said that programs designed to exploit the vulnerability will likely be available on the Internet soon.

The flaw is in a component of the operating system that allows other computers to request the Windows system perform an action or service. The component, known as the remote procedure call (RPC) process, facilitates such activities such as sharing files and allowing others to use the computer's printer.

By sending too much data to the RPC process, an attacker can cause the system to grant full access to the system. "
