Firefox < 37.0.2 Failed Plugin Memory Corruption

medium Nessus Plugin ID 82998
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Windows host contains a web browser that is affected by a memory corruption vulnerability.


The version of Firefox installed on the remote Windows host is prior to 37.0.2. It is, therefore, affected by a use-after-free error, related to the AsyncPaintWaitEvent() method, due to a race condition caused when plugin initialization fails. A remote attacker, using a crafted web page, can exploit this to execute arbitrary code.


Upgrade to Firefox 37.0.2 or later.
