Mozilla Firefox < 37.0.2 Failed Plugin Memory Corruption

high Nessus Network Monitor Plugin ID 8744
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 host has a web browser installed that is vulnerable to a use-after-free vulnerability.


Versions of Mozilla Firefox earlier than 37.0.2 are 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 specially crafted web page, can exploit this flaw to execute arbitrary code or cause a denial of service.


Upgrade to Firefox 37.0.2 or later.
