Can you be a bit more explicit about why this is whitelisted?

Something like
  BIND >= 9.11.2 need dhcpd >= 4.4.1, don't report it here since
  dhcpd is already recent enough.

Actual. checking isc dhcp sources, it appears the fix is sitting in
master and has not been merged to any of the stable branches. I have not
had the time to unpack and check in an OE env ti validate that.

Have you done that?

An like I said "it appears" and I alway verify with what sources get
unpacked. I finally got around to it doing that this morning and the
dhcp does have this fix.
