Synopsis

The remote Oracle Linux host is missing a security update.

Description

From Red Hat Security Advisory 2015:1207 :

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-2015-2724, CVE-2015-2725, CVE-2015-2722, CVE-2015-2727, CVE-2015-2728, CVE-2015-2729, CVE-2015-2731, CVE-2015-2733, CVE-2015-2734, CVE-2015-2735, CVE-2015-2736, CVE-2015-2737, CVE-2015-2738, CVE-2015-2739, CVE-2015-2740)

It was found that Firefox skipped key-pinning checks when handling an error that could be overridden by the user (for example an expired certificate error). This flaw allowed a user to override a pinned certificate, which is an action the user should not be able to perform. (CVE-2015-2741)

A flaw was discovered in Mozilla's PDF.js PDF file viewer. When combined with another vulnerability, it could allow execution of arbitrary code with the privileges of the user running Firefox.
(CVE-2015-2743)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Bob Clary, Christian Holler, Bobby Holley, Andrew McCreight, Terrence Cole, Steve Fink, Mats Palmgren, Wes Kocher, Andreas Pehrson, Jann Horn, Paul Bandha, Holger Fuhrmannek, Herre, Looben Yan, Ronald Crane, and Jonas Jenwald as the original reporters of these issues.

All Firefox users should upgrade to these updated packages, which contain Firefox version 38.1 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected firefox package.
