  Log Message:
  Update isc-dhcp4 package to 4.2.4p1 (ISC DHCP 4.2.4-P1).
  Fixes security problems.

  Changes since 4.2.4

  ! Previously the server code was relaxed to allow packets with zero
    length client ids to be processed.  Under some situations use of
    zero length client ids can cause the server to go into an infinite
    loop.  As such ids are not valid according to RFC 2132 section 9.14
    the server no longer accepts them.  Client ids with a length of 1
    are also invalid but the server still accepts them in order to
    minimize disruption.  The restriction will likely be tightened in
    the future to disallow ids with a length of 1.
    Thanks to Markus Hietava of Codenomicon CROSS project for the
    finding this issue and CERT-FI for vulnerability coordination.

  ! When attempting to convert a DUID from a client id option
    into a hardware address handle unexpected client ids properly.
