RHEL 6 / 7 : firefox (RHSA-2018:0122)

critical Nessus Plugin ID 106329

Synopsis

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

Description

An update for firefox is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Critical. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Mozilla Firefox is an open source web browser.

This update upgrades Firefox to version 52.6.0 ESR.

Security Fix(es) :

* Multiple flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2018-5089, CVE-2018-5091, CVE-2018-5095, CVE-2018-5096, CVE-2018-5097, CVE-2018-5098, CVE-2018-5099, CVE-2018-5102, CVE-2018-5103, CVE-2018-5104, CVE-2018-5117)

* To mitigate timing-based side-channel attacks similar to 'Spectre' and 'Meltdown', the resolution of performance.now() has been reduced from 5ms to 20ms.

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Christian Holler, Jason Kratzer, Marcia Knous, Nathan Froyd, Oriol Brufau, Ronald Crane, Randell Jesup, Tyson Smith, Cobos Alvarez, Ryan VanderMeulen, Sebastian Hengst, Karl Tomlinson, Xidorn Quan, Ludovic Hirlimann, Jason Orendorff, Looben Yang, Anonymous, Nils, and Xisigr as the original reporters.

Solution

Update the affected firefox and / or firefox-debuginfo packages.
