Microsoft is investigating new public reports of a vulnerability in supported versions of Microsoft Windows. Customers who are running Windows Server 2003 and Windows Server 2003 Service Pack 1 in their default configurations, with the Enhanced Security Configuration turned on, are not affected. We are also aware of proof of concept code published publicly. We are not aware of any attacks attempting to use the reported vulnerability or of customer impact at this time. We will continue to investigate these public reports.

The ActiveX control called out in the public reports and in the Proof of Concept code is the Microsoft WebViewFolderIcon ActiveX control (Web View). The vulnerability exists in Windows Shell and is exposed by Web View.

We are working on a security update currently scheduled for an October 10 release.

Customers are encouraged to keep their anti-virus software up to date.
