- 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

-it via the domain-search option; pretty escape semicolon as well
-(bnc#675052, CVE-2011-0997).

+- 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
