RHEL 4 : dhcp (RHSA-2009:1136)

critical Nessus Plugin ID 39798

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated dhcp packages that fix a security issue are now available for Red Hat Enterprise Linux 4 and 4.7 Extended Update Support.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

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 Mandriva Linux Engineering Team discovered a stack-based buffer overflow flaw in the ISC DHCP client. If the DHCP client were to receive a malicious DHCP response, it could crash or execute arbitrary code with the permissions of the client (root). (CVE-2009-0692)

Users of DHCP should upgrade to these updated packages, which contain a backported patch to correct this issue.

Solution

Update the affected dhclient, dhcp and / or dhcp-devel packages.
