Yeah, but we are quite understaffed atm, plus it's holidays so we're doing what
we can here.
@bind: please bump as necessary.
Thanks a lot Tobias.
Hi arches, please test and mark stable bind-9.4.1_p1
Additionally, but it is not needed for a possible GLSA, arm and s390 will have
to keyword bind-9.4.* if they want to be safe, unless someone backports the
fix.

Plus the corresponding bind-tools-9.4.1_p1 ;)

1. Emerges on AMD64.
2. No collisions etc.
3. Works.
It have not been in the tree for long, but this corrects security issues. I
have upgraded it on my server and it have been running for around 3 hours
without problems. Please mark stable on AMD64.

How can this be seen as a minor issue? Just because ISC plays it down!? Quite
the opposite, imho.
Please read http://www.trusteer.com/docs/bind9dns_s.html, summary below.
DNS cache poisoning is a very potent attack, made possible (in the case of BIND
9) by a flawed implementation of the DNS server, enabling an attacker to
predict DNS transaction IDs. With DNS cache poisoning, an attacker can redirect
traffic originally destined to a host name, to an IP address under his/her
control, thus effectively conducting a large-scale pharming attack affecting
all clients of the DNS server (ISP-wide or enterprise-wide).
agreed, but currently this kind of attack isn't explicitely mentioned in our
policy, maybe we should think about updating it to take that into account.
cc'ing amd64 again, you forgot to stable bind-tools too.
Btw, time vor glsa vote, and obviously voting yes :)

1. Emerges on AMD64.
2. No collisions.
3. Test phase ok.
4. Works (can't test nsupdate) - and tested with net-analyzer/gnome-nettool
rdep.
