Firefox < 31.0 Multiple Vulnerabilities (Mac OS X)

This script is Copyright (C) 2014-2016 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 installed on the remote host is a version prior
to 31.0. It is, therefore, affected by the following vulnerabilities :

- When a pair of NSSCertificate structures are added to a
trust domain and then one of them is removed during use,
a use-after-free error occurs which may cause the
application to crash. This crash is potentially
exploitable. (CVE-2014-1544)

- There are multiple memory safety hazards within the
browser engine. These hazards may lead to memory
corruption vulnerabilities, which may allow attackers
to execute arbitrary code. (CVE-2014-1547,

- A buffer overflow exists when interacting with the Web
Audio buffer during playback due to an error with the
allocation of memory for the buffer. This may lead to
a potentially exploitable crash. (CVE-2014-1549)

- A use-after-free exists in Web Audio due to the way
control messages are handled. This may lead to a
potentially exploitable crash. (CVE-2014-1550)

- There is an issue with the IFRAME sandbox same-origin
access policy which allows sandboxed content to access
other content from the same origin without approval.
This may lead to a same-origin-bypass vulnerability.

- Triggering the FireOnStateChange event has the
potential to crash the application. This may lead to
a use-after-free and an exploitable crash.

- When using the Cesium JavaScript library to generate
WebGL content, the application may crash. This crash
is potentially exploitable. (CVE-2014-1556)

- There is a flaw in the Skia library when scaling images
of high quality. If the image data is discarded while
being processed, the library may crash. This crash
is potentially exploitable. (CVE-2014-1557)

- There are multiple issues with using invalid
characters in various certificates. These invalid
characters may cause certificates to be parsed
incorrectly which may lead to the inability to use
valid SSL certificates. (CVE-2014-1558, CVE-2014-1559,

- It may be possible to spoof drag and drop events in
web content. This may allow limited ability to interact
with the UI. (CVE-2014-1561)
