privileges of the user running Thunderbird. (CVE-2011-2377)

(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,
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.
