FreeBSD : mozilla -- corrupt JIT state after deep return from native function (c1ef9b33-72a6-11de-82ea-0030843d3802)

high Nessus Plugin ID 39867
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 FreeBSD host is missing a security-related update.


Mozilla Project reports :

Firefox user zbyte reported a crash that we determined could result in an exploitable memory corruption problem. In certain cases after a return from a native function, such as escape(), the Just-in-Time (JIT) compiler could get into a corrupt state. This could be exploited by an attacker to run arbitrary code such as installing malware.

This vulnerability does not affect earlier versions of Firefox which do not support the JIT feature.


Update the affected package.
