Firefox < 16.0.2 Multiple Vulnerabilities (Mac OS X)

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Mac OS X host contains a web browser that is affected by
multiple vulnerabilities.

Description :

The installed version of Firefox is earlier than 16.0.2 and is
therefore potentially affected by the following security issues :

- The true value of 'window.location' can be shadowed by
user content through the use of the 'valueOf' method,
which can be combined with some plugins to perform
cross-site scripting attacks. (CVE-2012-4194)

- The 'CheckURL' function of 'window.location' can be
forced to return the wrong calling document and
principal, allowing a cross-site scripting attack.
(CVE-2012-4195)

- It is possible to use property injection by prototype to
bypass security wrapper protections on the 'Location'
object, allowing the cross-origin reading of the
'Location' object. (CVE-2012-4196)
