DUH? Those authors realized the implications years ago, and
took precautions that render them invulnerable today. Just
because others ignored logic does not make this 'new'.

But he was referring to their glibc, not ours;O

These 'revelations' only show the impact of rumors.

This IS the same old thing despite the newer codebase which
is affected, which adds more twists. Just because somebody
cracked a box in a lab does NOT constitute a good reason for
spreading alarm and panic.

I don't use Microsoft products, or Distributions as servers.
I don't even have a cache which can be poisoned.
I don't provide recursive DNS to the public. My DNS server
will reject out of zone queries. I don't need dnssec.
Source ports are randomized by design in my software.
Everything is behind firewalls on Nat. And I use HLFS.

You are crying wolf again. Take a Valium.
