Red Hat issued an update the same day the vulnerability in bind became known.
If you want your system to be secure, you will want to keep track of all
updates, and probably subscribe to firstname.lastname@example.org and/or
The missing link in the CERT advisory is annoying, but there's nothing we can do
about that, CERT don't update their advisories once they have been issued.
