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

Medium Nessus Plugin ID 95472

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.

Solution

Upgrade to Mozilla Firefox version 50.0.2 or later.
