Security Advisory Updated dhcp packages fix security vulnerabilities

Advisory: RHSA-2003:011-07
Type: Security Advisory
Severity: N/A
Issued on: 2003-01-16
Last updated on: 2003-01-16
Affected Products: Red Hat Linux 8.0
CVEs ( CVE-2003-0026


Several potential stack overflow vulnerabilities affect the ISC DHCPD
server. This advisory provides fixed packages for Red Hat Linux 8.0.

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

The Internet Software Consortium has detected several potential
vulnerabilities during an audit of the ISC DHCP server. These
vulnerabilities affect the minires library and may be exploitable as stack
buffer overflows, which could lead to remote code execution.

Red Hat Linux 8.0 shipped with a version of DHCP that is vulnerable to
these issues. All users of DHCP are advised to upgrade to the erratum
packages which contain a backported patch to correct this issue. Other
versions of Red Hat Linux and Red Hat Linux Advanced Server are based on
version 2 of DHCP, and are therefore not vulnerable to this issue.


Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
