Firefox < 36.0.4 SVG Bypass Privilege Escalation (Mac OS X)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote Mac OS X host contains a web browser that is affected by a
privilege escalation vulnerability.

Description :

The version of Mozilla Firefox installed on the remote Mac OS X host
is prior to 36.0.4. It is, therefore, affected by a privilege
escalation vulnerability due to a flaw within
'docshell/base/nsDocShell.cpp', which relates to SVG format content
navigation. A remote attacker can exploit this to bypass same-origin
policy protections, allowing a possible execution of arbitrary scripts
in a privileged context.
