CVE-2015-2741

Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Thunderbird to crash or,
potentially, execute arbitrary code with the privileges of the user
running Thunderbird. (CVE-2015-2724, CVE-2015-2725, CVE-2015-2731,
CVE-2015-2734, CVE-2015-2735, CVE-2015-2736, CVE-2015-2737, CVE-2015-2738,
CVE-2015-2739, CVE-2015-2740)

It was found that Thunderbird skipped key-pinning checks when handling an
error that could be overridden by the user (for example an expired
certificate error). This flaw allowed a user to override a pinned
certificate, which is an action the user should not be able to perform.
(CVE-2015-2741)

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

After installing the update, Thunderbird must be restarted for the changes
to take effect.
