[arch-general] Bind 9.6.1-1 patched against dynamic update ddos?

Hi, I've seen that there's a dynamic update ddos attack that is widely available on the net and after looking for the solution it seems that bind's latest patch (9.6.1-P1) solves this problem. So my question is more like this, is extra/bind 9.6.1-1 in the repository the same as bind 9.6.1-P1? The build date of the current package in extra/ says the 18 July but the homepage of BIND says the latest patch was published the 28 July. Best regards Fredrik Eriksson
