Integer overflow in Microsoft Internet Explorer 6
Flaw could cause a denial of service (crash) or allow remote access
There's a vulnerability within Microsoft Internet Explorer 6 while running on a fully patched Windows XP SP2 system that allows remote attackers to cause a denial of service (crash). This flaw is due to an integer overflow error in the Common Controls library "comctl32.dll" when processing a "WebViewFolderIcon" object with a specially crafted "setSlice()" method. Specifically, a 0x7fffffff argument to the setSlice method on a WebViewFolderIcon ActiveX object may lead to an invalid memory copy, which can be exploited by attackers. Successful execution, however, requires that the victim visit a specially crafted Web page.
