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-2014-1518, CVE-2014-1524, CVE-2014-1529,
CVE-2014-1531)

A use-after-free flaw was found in the way Thunderbird resolved hosts in
certain circumstances. An attacker could use this flaw to crash
Thunderbird or, potentially, execute arbitrary code with the privileges of
the user running Thunderbird. (CVE-2014-1532)

An out-of-bounds read flaw was found in the way Thunderbird decoded JPEG
images. Loading an email or a web page containing a specially crafted JPEG
image could cause Thunderbird to crash. (CVE-2014-1523)

A flaw was found in the way Thunderbird handled browser navigations
through history. An attacker could possibly use this flaw to cause the
address bar of the browser to display a web page name while loading
content from an entirely different web page, which could allow for cross-
site scripting (XSS) attacks. (CVE-2014-1530)

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.
