"An updated thunderbird package that fixes multiple security issues is
now available for Red Hat Enterprise Linux 5, 6, and 7.

Red Hat Product Security has rated this update as having Important
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 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."
