Synopsis :

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

Description :

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

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-2016-1930, CVE-2016-1935)

Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Bob Clary, Christian Holler, Nils
Ohlmeier, Gary Kwong, Jesse Ruderman, Carsten Book, Randell Jesup, and
Aki Helin as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla
security advisories for Thunderbird 38.6.0. 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 38.6.0, which corrects these issues.
After installing the update, Thunderbird must be restarted for the
changes to take effect.
