Online attackers are actively exploiting a vulnerability in Internet Explorer that allows them to execute malicious code on computers that visit booby-trapped websites, researchers said in an advisory that underscores the importance of installing a Microsoft patch as soon as possible.
The exploit of a critical IE bug, reported by researchers from antivirus provider McAfee, means there are two newly disclosed vulnerabilities in Microsoft products under attack. On Tuesday, Microsoft warned of a separate vulnerability in all supported versions of Windows that was also actively being exploited.
The most immediate significance of the McAfee report is this: If you run Windows and haven't installed Tuesday's batch of security fixes, you should stop whatever else you're doing and run them now.
