Microsoft released today an update to fix a flaw that allows a remote attacker to take over a computer with a Windows operating system without a user’s action.

Christopher Budd of Microsoft said, “This security update resolves a vulnerability in the Server service that affects all currently supported versions of Windows. Windows XP and older versions are rated as ‘Critical’ while Windows Vista and newer versions are rated as ‘Important.’ Because the vulnerability is potentially wormable on those older versions of Windows, we’re encouraging customers to test and deploy the update as soon as possible.”
