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
important 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 processing of malformed content. Malicious content
could cause Thunderbird to crash or execute arbitrary code with the
privileges of the user running Thunderbird. (CVE-2013-0787)

Red Hat would like to thank the Mozilla project for reporting this issue.
Upstream acknowledges VUPEN Security via the TippingPoint Zero Day
Initiative project 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.
