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-2015-0813, CVE-2015-0815, CVE-2015-0801)

A flaw was found in the way documents were loaded via resource URLs. An
attacker could use this flaw to bypass certain restrictions and under
certain conditions even execute arbitrary code with the privileges of the
user running Thunderbird. (CVE-2015-0816)

A flaw was found in the Beacon interface implementation in Thunderbird. A
web page containing malicious content could allow a remote attacker to
conduct a Cross-Site Request Forgery (CSRF) attack. (CVE-2015-0807)

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.
