Security Advisory dhcp security update

Advisory: RHSA-2005:212-06
Type: Security Advisory
Severity: Moderate
Issued on: 2005-04-12
Last updated on: 2005-04-12
Affected Products: Red Hat Enterprise Linux AS (v. 2.1)
Red Hat Enterprise Linux ES (v. 2.1)
Red Hat Linux Advanced Workstation 2.1 for the Itanium Processor
CVEs (cve.mitre.org): CVE-2004-1006

Details

An updated dhcp package that fixes a string format issue is now available
for Red Hat Enterprise Linux 2.1.

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

The dhcp package provides the ISC Dynamic Host Configuration Protocol
(DHCP) server and relay agent, dhcpd. DHCP is a protocol that allows
devices to get their own network configuration information from a server.

A bug was found in the way dhcpd logs error messages. A malicious DNS
server could send a carefully crafted DNS reply and cause dhcpd to crash or
possibly execute arbitrary code. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2005-0446 to this issue.

All users of dhcp should upgrade to this updated package, which contains a
backported patch and is not vulnerable to this issue.
