---------------------------------------------------------------------
                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated mailman packages available
Advisory ID:       RHSA-2002:099-04
Issue date:        2002-05-22
Updated on:        2002-06-06
Product:           Red Hat Linux
Keywords:          mailman cross-site scripting
Cross references:  RHSA-2002:100 RHSA-2002:101
Obsoletes:         
CVE Names:         CAN-2002-0388
---------------------------------------------------------------------

1. Topic:

Updated mailman packages are now available for Red Hat Linux 7.2 and 7.3. 
These updates resolve a cross-site scripting vulnerability present in
versions of Mailman prior to 2.0.11.

2. Relevant releases/architectures:

Red Hat Linux 7.2 - i386, ia64

Red Hat Linux 7.3 - i386

3. Problem description:

Two cross-site scripting vulnerabilities have been discovered in versions
of Mailman prior to version 2.0.11.

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):



6. RPMs required:

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at:
    http://www.redhat.com/about/contact/pgpkey.html

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>

                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Relaxed LPRng job submission policy
Advisory ID:       RHSA-2002:089-07
Issue date:        2002-05-16
Updated on:        2002-06-09
Product:           Red Hat Linux
Keywords:          LPRng
Cross references:  
Obsoletes:         RHSA-2001:077
CVE Names:         CAN-2002-0378
---------------------------------------------------------------------

1. Topic:

The LPRng print spooler, as shipped in Red Hat Linux 7.x, accepts all
remote print jobs by default.

2. Relevant releases/architectures:

Red Hat Linux 7.0 - alpha, i386

Red Hat Linux 7.1 - alpha, i386, ia64

Red Hat Linux 7.2 - i386, ia64

Red Hat Linux 7.3 - i386

3. Problem description:

With its default configuration, LPRng will accept job submissions from
any host, which is not appropriate in a workstation environment.  We
are grateful to Matthew Caron for pointing out this configuration
problem.

The Common Vulnerabilities and Exposures project (cve.mitre.org/) has
assigned the name CAN-2002-0378 to this issue.

The updated packages from this advisory change the job submission
policy (in /etc/lpd.perms) so that jobs from remote hosts are refused
by default.

Those running print servers may want to adjust this policy as
appropriate, for example to give access to certain hosts or subnets.
For details on how to do this see the lpd.perms(5) man page.

Since Red Hat Linux 7.1, default installations include ipchains rules
blocking remote access to the print spooler IP port; as a result those
installations already reject remote job submissions.  However, Red Hat
Linux 7 machines and any machine upgraded to a later release (as 
opposed to
having been freshly installed) will not have ipchains rules in place
by default.

IMPORTANT: There are special instructions for installing this update at
the end of the "Solution" section below.

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.

After upgrading, you should check that the new configuration file is
activated. To  do this, type the following command:

grep "X NOT SERVER" /etc/lpd.perms

If this commad returns no output, you will need to put the new
configuration file in place by typing:

mv /etc/lpd.perms.rpmnew /etc/lpd.perms
