New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 6.7


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


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.


Upgrade to Mozilla Firefox version 50.0.2 or later.
