openSUSE Security Update : dhcp (openSUSE-2016-887)

Synopsis :

The remote openSUSE host is missing a security update.

Description :

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.
