H D Moore has discovered a vulnerability in Microsoft Windows, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an error in the Windows Shell and is exposed via the "setSlice()" method in the WebViewFolderIcon ActiveX control (webvw.dll). This can e.g. be exploited via Internet Explorer by a malicious website to corrupt memory by passing specially crafted arguments to the "setSlice()" method.

Successful exploitation allows execution of arbitrary code.

NOTE: Exploit code is publicly available.

The vulnerability is confirmed on a fully patched system with Internet Explorer 6.0 and Microsoft Windows XP SP2. Other versions may also be affected.
