- CVE-2015-8605: A remote attacker could have used badly formed packets
 with an invalid IPv4 UDP length field to cause a DHCP server, client, or
 relay program to terminate abnormally (bsc#961305)
The following bugs were fixed:
- bsc#936923: Improper lease duration checking
- bsc#880984: Integer overflows in the date and time handling code
- bsc#956159: fixed service files to start dhcpd after slapd
- bsc#960506: Improve exit reason and logging when /sbin/dhclient-script
 is unable to pre-init requested interface
- bsc#947780: DHCP server could abort with 'Unable to set up timer: out of
 range' on very long or infinite timer intervals / lease lifetimes
- bsc#912098: dhclient could pretend to run while silently declining leases
- bsc#919959: server: Do not log success report before send reported
 success
- bsc#928390: dhclient dit not expose next-server DHCPv4 option to script
- bsc#926159: DHCP preferrend and valid lifetime would be logged
 incorrectly
- bsc#910686: Prevent a dependency conflict of dhcp-devel with bind-devel
 package The following tracked changes affect the build of the package only:
- bsc#891961: Disabled /sbin/service legacy-action hooks");
