 CVE-2011-0083
 CVE-2011-2362
 CVE-2011-2377

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.
