Red Hat Linux Advisory: iptables

Red Hat Security Advisory

1. Topic:

Updated iptables packages which are fully compatible with recent
kernel updates are now available.

2. Relevant releases/architectures:

Red Hat Linux 7.1 – i386
Red Hat Linux 7.2 – i386
Red Hat Linux 7.3 – i386
Red Hat Linux 8.0 – i386

3. Problem description:

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

Recent updates to the kernel in Red Hat Linux versions 7.1, 7.2,
7.3 and 8.0 did not also update the iptables utility, causing
functions such as owner match to stop working.

These issues could in some circumstances cause a firewall to
fail to restart after a kernel upgrade.

Users are therefore advised to upgrade to these erratum packages
which contain an update to version 1.2.8 of iptables.

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 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:

up2date

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

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla
for more info):

91040 – iptables-1.2.6a-2 not compatible with
kernel-2.4.20-13.8

These packages are GPG signed by Red Hat for security. Our key
is available from https://www.redhat.com/security/keys.html

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 md5sum with the
following command:

md5sum <filename>
