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

High Nessus Plugin ID 75814


The remote openSUSE host is missing a security update.


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

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 (bnc#712438).

- 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 dhcp.

- Disabled log-info level messages in dhclient(6) quiet mode to avoid excessive logging of non-critical messages (bnc#711420).


Update the affected dhcp packages.
