A new version of the ISC dhcp daemon is now available, which fixes many
security concerns. Users of Red Hat 5.0 and 5.1 who use dhcp (which was
called dhcpd in Red Hat 5.0) should upgrade to the new release immediately.
After upgrading, be sure to restart the dhcp daemon with the following command:

	/etc/rc.d/init.d/dhcpd restart

Thanks to Chris Evans for pointing out these problems, and to the ISC for
the fix.
