Mozilla Firefox < 50.0.2 nsSMILTimeContainer.cpp SVG Animation RCE

High Nessus Plugin ID 95475


The remote Windows host contains a web browser that is affected by a remote code execution vulnerability.


The version of Mozilla Firefox installed on the remote Windows 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.
