Summary
Red Hat Security Advisory: dhcp security update
Severity
Moderate
Notes
Topic: 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.
Details: 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.

CVE-2004-1006
