Hi List

dhcpcd-6.6.3 has been released with the following changes:
  *  Log which IP address we are ARPing.
  *  Only free other ARP states if not assinging an IPv4LL address.
  *  Reload global config when running per interface commands.
     This matches the signal behaviour.
  *  If we don't have a hardware address, fallback to creating a default
     IAID from the interface name and index as we used to.
  *  Loopback interfaces have routes scoped to the host only.
  *  If we don't have a hwlen and no clientid has been set, force a DUID
     based ClientID.
  *  Disable IPv6RS if a loopback, pointopoint or not a multicast 
interface.
  *  If allowinterfaces is not specified, allow all configured 
interfaces
     to work, such as loopback and ppp.
  *  When not daemonising, don't exit on timeout.
  *  Zero length UDP packets are not an error condition on the socket.
     Thanks to Michał Kępień.
  *  If the IP address is still on the interface when reading a lease,
     fake add the address and routes so the lease can be cleaned up if 
needed.

From dhcpcd-6.3.3 to 6.6.2, dhcpcd was vulnerable to a zero length UDP 
packet which would cause the socket to close resulting in a DoS.
For IPv4 sockets, triggering a carrier reset would be enough to re-open 
the socket.
For IPv6 sockets, dhcpcd would have to be restarted.
All users dhcpcd-6.3.3 and upwards are encouraged to upgrade or apply 
this patch:
