You really need to take that bananna out of your mouth, I'm starting to feel
sorry for you.
The point is dhclient was vulnerable, and it was making peoples machines
vulnerable at the same time, and there were year old bug reports on it
getting ignored.
Any vulnerability is an attack vector. You are arguing semantics again,
the same as trying to say privacy and security is different then what makes
proprietary software "unethical".
Its not, they are the same thing. Stop arguing for the sake of argument.
Your community is what looks foolish.
