Description


Updated firefox packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 5, 6, and 7.

Red Hat Product Security has rated this update as having Critical security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.

Multiple security flaws were found in the graphite2 font library shipped
with Firefox. 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-2016-1521, CVE-2016-1522, CVE-2016-1523)

All Firefox users should upgrade to these updated packages, which contain
Firefox version 38.6.1 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
