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 vulnerability from the CVE links in the References section.

[Updated 25 August 2014] This erratum previously included an incorrect list of fixed issues. The issue list has been updated to reflect the CVEs that were fixed in this update. The firefox packages provided by this advisory have not been modified in any way.

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-2015-4500, CVE-2015-4506, CVE-2015-4509, CVE-2015-4511, CVE-2015-4517, CVE-2015-4521, CVE-2015-4522, CVE-2015-7174, CVE-2015-7175, CVE-2015-7176, CVE-2015-7177, CVE-2015-7180)

Two information leak flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to disclose sensitive information or, in certain cases, crash.
(CVE-2015-4519, CVE-2015-4520)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Andrew Osmond, Olli Pettay, Andrew Sutherland, Christian Holler, David Major, Andrew McCreight, Cameron McCormack, Khalil Zhani, Atte Kettunen, Ronald Crane, Mario Gomes, and Ehsan Akhgari as the original reporters of these issues.

All Firefox users should upgrade to these updated packages, which contain Firefox version 38.3.0 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected firefox and / or firefox-debuginfo packages.
