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.

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-2015-0836, CVE-2015-0831, CVE-2015-0827)

An information leak flaw was found in the way Firefox implemented autocomplete forms. An attacker able to trick a user into specifying a local file in the form could use this flaw to access the contents of that file. (CVE-2015-0822)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Carsten Book, Christoph Diehl, Gary Kwong, Jan de Mooij, Liz Henry, Byron Campen, Tom Schuster, Ryan VanderMeulen, Paul Bandha, Abhishek Arya, and Armin Razmdjou as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 31.5.0 ESR. You can find a link to the Mozilla advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which contain Firefox version 31.5.0 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected packages.
