Fedora Legacy Update Advisory

Synopsis: Updated iptables packages resolve security issues
Advisory ID: FLSA:2252
Issue date: 2005-02-10
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2252
CVE Names: CAN-2004-0986
---------------------------------------------------------------------


---------------------------------------------------------------------
1. Topic:

Updated iptables packages that correct a security problem are now available.

The iptables utility controls the network packet filtering code in the Linux kernel.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386

3. Problem description:

Under certain conditions, iptables did not properly load the required modules at system startup, which caused the firewall rules to fail to load and protect the system from remote attackers. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0986 to this issue.

Users of iptables are advised to upgrade to these errata packages, which contain backported patches correcting these issues.

4. Solution:

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 yum and apt. Many people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www fedoralegacy.org/docs for directions on how to configure yum and apt-get.

These packages are GPG signed by Fedora Legacy for security. Our key is available from http://www.fedoralegacy.org/about/security.php

You can verify each package with the following command:

rpm --checksig -v filename

If you only wish to verify that each package has not been corrupted or tampered with, examine only the sha1sum with the following command:

sha1sum filename
