openSUSE Security Update : dhcp (openSUSE-SU-2011:1021-1)

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.

Synopsis :

The remote openSUSE host is missing a security update.

Description :

This update of dhcp fixes two Denial of Service (CVE-2011-2748,
CVE-2011-2749) vulnerabilities caused by specially crafted BOOTP

Also following bugs were fixed :

- Moved server pid files into chroot directory even chroot
is not used and create a link in /var/run, so it can
write one when started as user without chroot and avoid
stop problems when the chroot sysconfig setting changed

- Fixed dhclient-script to not remove alias IP when it
didn't changed to not wipe out iptables connmark when
renewing the lease (bnc#700771). Thanks to James Carter
for the patch.

- Removed GPL licensed files (bind-*/contrib/dbus) from
bind.tgz to ensure, they're not used to build non-GPL

- Disabled log-info level messages in dhclient(6) quiet
mode to avoid excessive logging of non-critical messages
