Synopsis: Important: thunderbird security update
Advisory ID: SLSA-2015:1682-1
Issue Date: 2015-08-25
CVE Numbers: CVE-2015-4473
 CVE-2015-4491
 CVE-2015-4487
 CVE-2015-4488
 CVE-2015-4489
--

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-2015-4473, CVE-2015-4491, CVE-2015-4487,
CVE-2015-4488, CVE-2015-4489)

Note: All of the above issues cannot be exploited by a specially crafted
HTML mail message because JavaScript is disabled by default for mail
messages. However, they could be exploited in other ways in Thunderbird
(for example, by viewing the full remote content of an RSS feed).

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