Synopsis :

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

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

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-2015-4488, 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, Andre Bargull, Massimiliano Tomassoli, laf.intel,
Massimiliano Tomassoli, Tyson Smith, Jukka Jylanki, 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.
