The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2012:1140 :
Updated dhcp packages that fix one security issue are now available
for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.
The Dynamic Host Configuration Protocol (DHCP) is a protocol that
allows individual devices on an IP network to get their own network
configuration information, including an IP address, a subnet mask, and
a broadcast address.
A denial of service flaw was found in the way the dhcpd daemon handled
zero-length client identifiers. A remote attacker could use this flaw
to send a specially crafted request to dhcpd, possibly causing it to
enter an infinite loop and consume an excessive amount of CPU time.
Upstream acknowledges Markus Hietava of the Codenomicon CROSS project
as the original reporter of this issue.
Users of DHCP should upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing this
update, all DHCP servers will be restarted automatically.
