RHEL 4 / 5 / 6 : thunderbird (RHSA-2011:1267)

High Nessus Plugin ID 56113


The remote Red Hat host is missing one or more security updates.


An updated thunderbird package that fixes one security issue is now available for Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having important security impact.

Mozilla Thunderbird is a standalone mail and newsgroup client.

The RHSA-2011:1243 Thunderbird update rendered HTTPS certificates signed by a certain Certificate Authority (CA) as untrusted, but made an exception for a select few. This update removes that exception, rendering every HTTPS certificate signed by that CA as untrusted.

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.


Update the affected thunderbird and / or thunderbird-debuginfo packages.
