Microsoft Plugs Windows Hole Exploited By Stuxnet

Microsoft has patched a hole in its Windows operating system, which was being exploited by Stuxnet virus.

The security bulletin MS10-061, which was released as a part of the Patch Tuesday release, fixes a vulnerability in the Print Spooler service, which is capable of allowing remote code execution with the help of a maliciously crafted print request.

“This vulnerability in the Print Spooler Service is rated Critical for Windows XP and Important on all other affected platforms and is used by Stuxnet to spread to systems inside the network where the Print Spooler service is exposed without authentication,” the company wrote on the Microsoft Security Response Center blog.

According to security software makers Kaspersky and Symantec, the hole was being exploited by the Stuxnet worm and had been rated 'critical' for Windows XP operating system.

Microsoft has labelled the vulnerability as 'important' for newer versions of its Windows OS.

Tech news site Cnet reports that the vulnerability was being exploited by the Stuxnet worm to infect industrial control systems and could be spread from Windows to any other network.
