Several flaws were found in the processing of malformed content. Malicious
content could cause Thunderbird to crash or, potentially, execute arbitrary
code with the privileges of the user running Thunderbird. (CVE-2012-4214,
CVE-2012-4215, CVE-2012-4216, CVE-2012-5829, CVE-2012-5830, CVE-2012-5833,
CVE-2012-5835, CVE-2012-5839, CVE-2012-5840, CVE-2012-5842)
A buffer overflow flaw was found in the way Thunderbird handled GIF
(Graphics Interchange Format) images. Content containing a malicious GIF
image could cause Thunderbird to crash or, possibly, execute arbitrary code
with the privileges of the user running Thunderbird. (CVE-2012-4202)
A flaw was found in the way Thunderbird decoded the HZ-GB-2312 character
encoding. Malicious content could cause Thunderbird to run JavaScript code
with the permissions of different content. (CVE-2012-4207)
A flaw was found in the location object implementation in Thunderbird.
Malicious content could possibly use this flaw to allow restricted content
to be loaded by plug-ins. (CVE-2012-4209)
A flaw was found in the way cross-origin wrappers were implemented.
Malicious content could use this flaw to perform cross-site scripting
attacks. (CVE-2012-5841)
A flaw was found in the evalInSandbox implementation in Thunderbird.
Malicious content could use this flaw to perform cross-site scripting
attacks. (CVE-2012-4201)
Note: All issues except CVE-2012-4202 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.
