Firefox ESR 31.x < 31.4 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 31.4. It is, therefore, affected by the following
vulnerabilities :

- Multiple unspecified memory safety issues exist within
the browser engine. (CVE-2014-8634, CVE-2014-8635)

- A flaw exists in 'navigator.sendBeacon()' in which it
does not follow the cross-origin resource sharing
specification. This results in requests from
'sendBeacon()' lacking an 'origin' header, which allows
malicious sites to perform XSRF attacks. (CVE-2014-8638)

- A flaw exists when receiving 407 Proxy Authentication
responses with a 'set-cookie' header. This can allow
a session-fixation attack. (CVE-2014-8639)

- A read-after-free flaw exists in WebRTC due to the way
tracks are handled, which can result in a potentially
exploitable crash or incorrect WebRTC behavior.
