Synopsis :

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

Description :

An updated thunderbird package that fixes one security issue is now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
critical security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

Mozilla Thunderbird is a standalone mail and newsgroup client.

A flaw was found in the way Thunderbird handled security wrappers.
Malicious content could cause Thunderbird to execute arbitrary code
with the privileges of the user running Thunderbird. (CVE-2012-4193)

Red Hat would like to thank the Mozilla project for reporting this
issue. Upstream acknowledges moz_bug_r_a4 as the original reporter.

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

All Thunderbird users should upgrade to this updated package, which
corrects this issue. After installing the update, Thunderbird must be
restarted for the changes to take effect.
