FL 7.3: dhcp 2.x CAN-2004-1006

[Ville Herva <vherva@xxxxxxxxxx>]

Regarding dhcp CAN-2004-1006: see
  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1006
  http://www.debian.org/security/2004/dsa-584
  and 
  http://secunia.com/advisories/13112/

I separated the fix for CAN-2004-1006 from the Debian dhcp package diff
  http://security.debian.org/pool/updates/main/d/dhcp/dhcp_2.0pl5-11woody1.diff.gz
See the attached patch dhcp.CAN-2004-1006. (I hope I got the whole hunk -
Debian does not mark individual fixes in their diff.)

The patch appears to apply cleanly to the dhcp-2.0pl5-8.src.rpm:
  ftp://ftp.redhat.com/pub/redhat/linux/7.3/en/os/i386/SRPMS/dhcp-2.0pl5-8.src.rpm
(which is the same that shipped with RH72 and RHEL21 afaict, and newer
doesn't seem to be available in the updates either.)

I merely added lines
  Patch3: dhcp.CAN-2004-1006
and 
  %patch3 -p1
to the .spec and upped Release.

Should this fix be pushed via FL73, too?
