A. Kuznetsov's iputils is based on netkit-base. A quick glance at netkit-base source
would seem to indicate that static buffer problems (and naturally root dropping) are
still there in netkit-base.
Perhaps there should be an errata release which would tell people to move to inetd + iputils?
IF this is done, this would be a good place to fix the close-wait DoS issue if daytime server
is being used (#16729) -- a patch is available.
Hmm - I believe RedHat6.0 shipped with a patch closing the static buffer
It is called "ping-overflow.patch".
In summary: I think RH6.0 ping is safe as shipped.
