1. Topic:

A new version of iptables fixing various minor security problems and some 
other bugs is available.

2. Relevant releases/architectures:

Red Hat Linux 7.1 - alpha, i386

Red Hat Linux 7.2 - i386

3. Problem description:

Some problems in earlier releases of iptables could lead to bad 
iptables-save files, causing the firewall not to come up when iptables 
was restarted (e.g. at system reboot).

This release also fixes some other problems.

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:


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):

42990 - iptables-save: -c option causing problems as of 1.2.2-1.i386
50500 - iptables-save saves --reject-with icmp-host-prohibited as --reject-with tcp-reset
53325 - Errata conversion of iptables .... -m limit ##/sec
54280 - string_to_number buglets
31133 - do not assume that nat, mangle tables exist
54160 - iptables-save and iptables-restore parse and produce quotes differently from each other

6. RPMs required:

Red Hat Linux 7.1:




Red Hat Linux 7.2:
