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-2013-0788)

A flaw was found in the way Same Origin Wrappers were implemented in
Thunderbird. Malicious content could use this flaw to bypass the same-
origin policy and execute arbitrary code with the privileges of the user
running Thunderbird. (CVE-2013-0795)

A flaw was found in the embedded WebGL library in Thunderbird. Malicious
content could cause Thunderbird to crash or, potentially, execute
arbitrary code with the privileges of the user running Thunderbird. Note:
This issue only affected systems using the Intel Mesa graphics drivers.
(CVE-2013-0796)

An out-of-bounds write flaw was found in the embedded Cairo library in
Thunderbird. Malicious content could cause Thunderbird to crash or,
potentially, execute arbitrary code with the privileges of the user
running Thunderbird. (CVE-2013-0800)

A flaw was found in the way Thunderbird handled the JavaScript history
functions. Malicious content could cause a page to be displayed that has a
baseURI pointing to a different site, allowing cross-site scripting (XSS)
and phishing attacks. (CVE-2013-0793)

Note: All issues except CVE-2013-0800 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.
