Oracle Linux 7 : dhcp (ELSA-2018-0158)

Low Nessus Plugin ID 106365

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

From Red Hat Security Advisory 2018:0158 :

An update for dhcp is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) 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. The dhcp packages provide a relay agent and ISC DHCP service required to enable and administer DHCP on a network.

Security Fix(es) :

* It was found that the DHCP daemon did not properly clean up closed OMAPI connections in certain cases. A remote attacker able to connect to the OMAPI port could use this flaw to exhaust file descriptors in the DHCP daemon, leading to a denial of service in the OMAPI functionality. (CVE-2017-3144)

Solution

Update the affected dhcp packages.
