This update for dhcp fixes the following issues:

Security issue fixed:
- CVE-2016-2774: Fixed a denial of service attack against the DHCP server over the OMAPI TCP socket, which could be used
  by network adjacent attackers to make the DHCP server non-functional (bsc#969820).

Non security issues fixed:
- Rename freeaddrinfo(), getaddrinfo() and getnameinfo() in the internal libirs
  library that does not consider /etc/hosts and /etc/nsswitch.conf to use irs_
  prefix. This prevents name conflicts which would result in overriding standard
  glibc functions used by libldap. (bsc#972907)
