Mozilla Firefox < 50.0.2 nsSMILTimeContainer.cpp SVG Animation RCE (macOS)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

The remote macOS or Mac OS X host contains a web browser that is
affected by a remote code execution vulnerability.

Description :

The version of Mozilla Firefox installed on the remote macOS or Mac
OS X host is prior to 50.0.2. It is, therefore, affected by a
use-after-free error in dom/smil/nsSMILTimeContainer.cpp when handling
SVG animations. An unauthenticated, remote attacker can exploit this
issue, via a specially crafted web page, to deference already freed
memory, resulting in the execution of arbitrary code.
