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.

Several 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-2015-4473, CVE-2015-4475, CVE-2015-4478, CVE-2015-4479,
CVE-2015-4480, CVE-2015-4493, CVE-2015-4484, CVE-2015-4491, CVE-2015-4485,
CVE-2015-4486, CVE-2015-4487, CVE-2015-4488, CVE-2015-4489, CVE-2015-4492)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Gary Kwong, Christian Holler, Byron Campen, Aki
Helin, André Bargull, Massimiliano Tomassoli, laf.intel, Massimiliano
Tomassoli, Tyson Smith, Jukka Jylänki, Gustavo Grieco, Abhishek Arya,
Ronald Crane, and Looben Yang as the original reporters of these issues.

All Firefox users should upgrade to these updated packages, which contain
Firefox version 38.2 ESR, which corrects these issues. After installing the
update, Firefox must be restarted for the changes to take effect.
