An update that solves one vulnerability and has four security fixes can now be installed.

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)
