Mozilla Thunderbird 3.1 < 3.1.9 Invalid HTTP Certificates

Medium Nessus Plugin ID 52768


The remote Windows host contains a mail client with an out-of-date SSL certificate blacklist.


The installed version of Thunderbird 3.1 is earlier than 3.1.9. Such versions have an out-of-date SSL certificate blacklist.

A certificate authority (CA) has revoked a number of fraudulent SSL certificates for several prominent public websites.

If an attacker can trick someone into using the affected browser and visiting a malicious site using one of the fraudulent certificates, he may be able to fool that user into believing the site is a legitimate one. In turn, the user could send credentials to the malicious site or download and install applications.


Upgrade to Thunderbird 3.1.9 or later.
