   An update that solves one vulnerability and has four fixes
   is now available.

Description:

    This update for dhcp fixes several issues.

   This security issue was fixed:

   - CVE-2017-3144: OMAPI code didn't free socket descriptors when empty
     message is received allowing DoS (bsc#1076119).

   These non-security issues were fixed:

   - Optimized if and when DNS client context and ports are initted
     (bsc#1073935)
   - Relax permission of dhclient-script for libguestfs (bsc#987170)
   - Modify dhclient-script to handle static route updates (bsc#1023415).
   - Use only the 12 least significant bits of an inbound packet's TCI value
     as the VLAN ID to fix some packages being wrongly discarded by the Linux
     packet filter. (bsc#1059061)
