"An updated thunderbird package that fixes multiple security issues is
now available for Red Hat Enterprise Linux 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-2015-0836, CVE-2015-0831,
CVE-2015-0827)

An information leak flaw was found in the way Thunderbird 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)

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 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 Thunderbird 31.5.0. 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 31.5.0, which corrects these issues.
After installing the update, Thunderbird must be restarted for the
changes to take effect."
