Synopsis:    Important: thunderbird security update
Issue Date:  2011-08-31


Mozilla Thunderbird is a standalone mail and newsgroup client.

It was found that a Certificate Authority (CA) issued a fraudulent HTTPS
certificate. This update renders any HTTPS certificates signed by that
CA as untrusted, except for a select few. The now untrusted certificates
that were issued before July 1, 2011 can be manually re-enabled and used
again at your own risk in Thunderbird; however, affected certificates
issued after this date cannot be re-enabled or used.

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