- Updated to ISC dhcp-4.2.2 release, providing two security fixes
(CVE-2011-2748,CVE-2011-2749,[ISC-Bugs #24960],bnc#712653), that
allowed remote attackers to cause a denial of service (a daemon
exit) via crafted BOOTP packets. Further also DNS update fix to
detect overlapping pools or misconfigured fixed-address entries,
that caused a server crash during DNS update and other fixes.
For a complete list, please see the RELNOTES file provided in
the package and also available online at http://www.isc.org/.
- Merged/adopted dhclient option-checks, send-hostname-rml, ldap
patch, xen-checksum, close-on-exec patches and removed obsolete
in6_pktinfo-prototype and relay-no-ip-on-interface patches.
- 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).
- Disabled log-info level messages in dhclient(6) quiet mode to
avoid excessive logging of non-critical messages (bnc#711420).
- 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.
- Fixed DDNS-howto.txt reference in the config file; it has been
moved to the dhcp-doc package (bnc#697279).
- Removed GPL licensed files (bind-*/contrib/dbus) from bind.tgz
to ensure, they're not used to build non-GPL dhcp (bnc#714004).
- Changed to apply strict-aliasing/RELRO for >= 12.x only
