Summary
Security update for dhcp

Notes

Title of the patch
Security update for dhcp
Description of the patch
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)
