Firefox ESR 31.x < 31.6 Multiple Vulnerabilities (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
multiple vulnerabilities.

Description :

The version of Firefox ESR 31.x installed on the remote Mac OS X host
is prior to 31.6. It is, therefore, affected by the following
vulnerabilities :

- A privilege escalation vulnerability exists which
relates to anchor navigation. A remote attacker can
exploit this to bypass same-origin policy protections,
allowing a possible execution of arbitrary scripts in a
privileged context. Note that this is a variant of
CVE-2015-0818 that was fixed in Firefox ESR 31.5.3.

- Access to certain privileged internal methods is
retained when navigating from windows created to contain
privileged UI content to unprivileged pages. An attacker
can exploit this to execute arbitrary JavaScript with
elevated privileges. (CVE-2015-0802)

- A cross-site request forgery (XSRF) vulnerability exists
in the sendBeacon() function due to cross-origin
resource sharing (CORS) requests following 30x
redirections. (CVE-2015-0807)

- Multiple memory safety issues exist within the browser
engine. A remote attacker can exploit these to corrupt
memory and possibly execute arbitrary code.

- A privilege escalation vulnerability exists related to
documents loaded through a 'resource:' URL. An attacker
can exploit this to load pages and execute JavaScript
with elevated privileges. (CVE-2015-0816)
