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

High Nessus Plugin ID 39867


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.
