RHEL 5 / 6 / 7 : thunderbird (RHSA-2015:1455)

Synopsis

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

Description

The remote Redhat Enterprise Linux 5 / 6 / 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2015:1455 advisory.

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2015-2724, CVE-2015-2725, CVE-2015-2731, 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 Thunderbird 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)

Note: All of the above issues cannot be exploited by a specially crafted HTML mail message as JavaScript is disabled by default for mail messages.
They could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed.

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Bob Clary, Christian Holler, Bobby Holley, Andrew McCreight, Herre, Ronald Crane, and David Keeler as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 31.8. You can find a link to the Mozilla advisories in the References section of this erratum.

All Thunderbird users should upgrade to this updated package, which contains Thunderbird version 31.8, which corrects these issues.
After installing the update, Thunderbird 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 thunderbird package based on the guidance in RHSA-2015:1455.
