                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated postfix packages are available
Advisory ID:       RHSA-2001:156-05
Issue date:        2001-11-15
Updated on:        2001-11-27
Product:           Red Hat Powertools
Keywords:          postfix session log memory exhaustion denial of service
Cross references:  
Obsoletes:         
---------------------------------------------------------------------

1. Topic:

Updated postfix packages are now availble that will fix a possible
denial of service attack.

2. Relevant releases/architectures:

Red Hat Powertools 7.1 - alpha, i386

3. Problem description:

A malicious user could get postfix to exhaust a machine's memory by
abusing its session cache which could result in a denial of service
attack.  The updated postfix packages will fix these potential
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:

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):

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at:

You can verify each package with the following command:
    rpm --checksig  <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:
    rpm --checksig --nogpg <filename>
