3. Description:

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. (BZ#734316)

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

734316 - Fraudulent certificates signed by DigiNotar CA certificate (MFSA 2011-34)
