An update for firefox is now available for Red Hat Enterprise Linux 5, 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 45.5.0 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-2016-5296, CVE-2016-5297, CVE-2016-9066, CVE-2016-5291, CVE-2016-5290)

  • A flaw was found in the way Add-on update process was handled by Firefox. A Man-in-the-Middle attacker could use this flaw to install a malicious signed add-on update. (CVE-2016-9064)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Abhishek Arya, Andre Bargull, Samuel Gross, Yuyang Zhou, Olli Pettay, Christian Holler, Ehsan Akhgari, Jon Coppeard, Gary Kwong, Tooru Fujisawa, Philipp, and Randell Jesup as the original reporters.
