Synopsis

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

Description

The remote Redhat Enterprise Linux 6 / 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2015:1586 advisory.

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, Andr Bargull, Massimiliano Tomassoli, laf.intel, Massimiliano Tomassoli, Tyson Smith, Jukka Jylnki, 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL firefox package based on the guidance in RHSA-2015:1586.
