Synopsis

Critical: thunderbird security update

Type/Severity

Security Advisory: Critical

Topic

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 critical
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.

Description

Mozilla Thunderbird is a standalone mail and newsgroup client.

A flaw was found in the way Thunderbird handled malformed JPEG images. An
HTML mail message containing a malicious JPEG image could cause Thunderbird
to crash or, potentially, execute arbitrary code with the privileges of the
user running Thunderbird. (CVE-2011-2377)

Multiple dangling pointer flaws were found in Thunderbird. Malicious HTML
content could cause Thunderbird to crash or, potentially, execute arbitrary
code with the privileges of the user running Thunderbird. (CVE-2011-0083,
CVE-2011-0085, CVE-2011-2363)

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-2011-2364, CVE-2011-2365, CVE-2011-2374, CVE-2011-2375, CVE-2011-2376)

It was found that Thunderbird could treat two separate cookies (for web
content) as interchangeable if both were for the same domain name but one
of those domain names had a trailing "." character. This violates the
same-origin policy and could possibly lead to data being leaked to the
wrong domain. (CVE-2011-2362)

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.
