3. Description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed HTML mail content.
An HTML mail message containing malicious content could cause Thunderbird
to crash or, potentially, execute arbitrary code as the user running
Thunderbird. (CVE-2009-1392, CVE-2009-1303, CVE-2009-1305, CVE-2009-1833,
CVE-2009-1838)

Several flaws were found in the way malformed HTML mail content was
processed. An HTML mail message containing malicious content could execute
arbitrary JavaScript in the context of the mail message, possibly
presenting misleading data to the user, or stealing sensitive information
such as login credentials. (CVE-2009-1306, CVE-2009-1307, CVE-2009-1309)

Note: JavaScript support is disabled by default in Thunderbird. None of the
above issues are exploitable unless JavaScript is enabled.

All Thunderbird users should upgrade to this updated package, which
resolves these issues. All running instances of Thunderbird must be
restarted for the update to take effect.

Before applying this update, make sure that all previously-released
