This reporter is absurdly clueless. Firstly, it is in no way remarkable 
to work with vendors to release a patch and advisory. That is what is 
expected of security researchers. Secondly, holding a press conference 
announcing a critical flaw without providing users any relevant details 
is not "responsible disclosure" in the slightest. The patches have 
already been released, and people of all different hats are already 
working on determining the nature of the flaws. In the meantime, users 
are left unable to accurately gauge their risk.

The worst part is, the ISC "fix" is a joke - it doesn't even correctly 
randomize query source ports, instead using the same source port for the 
lifetime of the process. It's been commonly known for well over a decade 
that randomizing query source ports markedly increases difficulty of 
spoofing, and BIND *still* can't get it right.
