Synopsis

The remote Red Hat host is missing one or more security updates for firefox.

Description

The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2018:3005 advisory.

Mozilla Firefox is an open-source web browser, designed for standards compliance, performance, and portability.

This update upgrades Firefox to version 60.3.0 ESR.

Security Fix(es):

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Christian Holler, Bob Owen, Boris Zbarsky, Calixte Denizet, Jason Kratzer, Jed Davis, Taegeon Lee, Philipp, Ronald Crane, Raul Gurzau, Gary Kwong, Tyson Smith, Raymond Forbes, Bogdan Tara, Nils, r, Rob Wu, Andrew Swan, and Daniel Veditz as the original reporters.

Bug Fix(es):

* Previously, passwords saved in the Firefox browser and encrypted by a master password were erased when Firefox was exited. This update ensures that NSS files used to decrypt stored login data are handled correctly. As a result, the affected passwords are no longer lost after restarting Firefox. (BZ#1638082)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
