"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 45.1.0 ESR.

Security Fix(es) :

* Multiple flaws were found in the processing of malformed web
content. A web page containing malicious content could cause Firefox

of the user running Firefox. (CVE-2016-2805, CVE-2016-2806,
CVE-2016-2807, CVE-2016-2808, CVE-2016-2814)
