Issue date:	2009-06-25
CVE Names:	CVE-2009-1303 CVE-2009-1305 CVE-2009-1306
                   CVE-2009-1307 CVE-2009-1308 CVE-2009-1309
                   CVE-2009-1392 CVE-2009-1833 CVE-2009-1836
                   CVE-2009-1838

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-2009-1308, CVE-2009-1309)

A flaw was found in the way Thunderbird handled error responses returned
from proxy servers. If an attacker is able to conduct a 
man-in-the-middle attack against a Thunderbird instance that is using a 
proxy server, they may be able to steal sensitive information from the 
site Thunderbird is displaying. (CVE-2009-1836)

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

All running instances of Thunderbird must be restarted for the update to 
take effect.
