Synopsis :

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

Description :

An updated thunderbird package that fixes several security issues is
now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate 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 HTML content.
Malicious HTML content could cause Thunderbird to crash or,
potentially, execute arbitrary code with the privileges of the user
running Thunderbird. (CVE-2010-3776, CVE-2010-3777)

Note: JavaScript support is disabled in Thunderbird for mail messages.
The above issues are believed to not be exploitable without
JavaScript.

This update adds support for the Sanitiser for OpenType (OTS) library
to Thunderbird. This library helps prevent potential exploits in
malformed OpenType fonts by verifying the font file prior to use.
(CVE-2010-3768)

All Thunderbird users should upgrade to this updated package, which
resolves these issues. All running instances of Thunderbird must be
restarted for the update to take effect.
