   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.
