Multiple regressions in dnsmasq 2.43, merge to 2.45 needed

Binary package hint: dnsmasq

Release 2.43 has been merged in intrepid to fix a security issue.
However this release introduces multiple regressions that have been fixed in releases 2.44 and 2.45 :

version 2.44
            Fix crash when unknown client attempts to renew a DHCP
            lease, problem introduced in version 2.43. Thanks to
            Carlos Carvalho for help chasing this down.

     Fix potential crash when a host which doesn't have a lease
     does DHCPINFORM. Again introduced in 2.43. This bug has
     never been reported in the wild.

            Fix crash in netlink code introduced in 2.43. Thanks to
            Jean Wolter for finding this.

version 2.45
            Fix total DNS failure in release 2.43 unless --min-port
            specified. Thanks to Steven Barth and Grant Coady for
            bugreport. Also reject out-of-range port spec, which could
            break things too: suggestion from Gilles Espinasse.
