               Fedora Legacy Update Advisory

Synopsis:          Updated mailman resolves security vulnerability
Advisory ID:       FLSA:1734
Issue date:        2004-07-19
Product:           Red Hat Linux
Keywords:          Bugfix
Cross references:  https://bugzilla.fedora.us/show_bug.cgi?id=1734
CVE Names:         CAN-2004-0412

1. Topic:

Updated mailman packages that fixes a remote security vulnerability are now 

2. Relevent releases/architectures:

Red Hat Linux 9 - i386

3. Problem description:

Mailman is software to help manage email discussion lists, much like 
Majordomo and Smartmail. Unlike most similar products, Mailman gives each 
mailing list a webpage, and allows users to subscribe, unsubscribe, etc. 
over the Web. Even the list manager can administer his or her list 
entirely from the Web. Mailman also integrates most things people want to 
do with mailing lists, including archiving, mail <-> news gateways, and so 

A flaw in Mailman 2.1.* allows a remote attacker to retrieve the mailman 
password of any subscriber by sending a carefully crafted email request to 
the mailman server.

A simple patch is available and is fixed upstream in Mailman 2.1.5.

All users are advised to upgrade to these updated packages, which contain a 
backported fix and are not vulnerable to this issue.

Fedora Legacy would like to thank Marc Deslauriers for reporting this 

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.

5. Bug IDs fixed:

http://bugzilla.fedora.us - 1734 - CAN-2004-0412 Mailman password retrieval

6. RPMs required:

Red Hat Linux 9:



7. Verification:

SHA1 sum                                 Package Name
- - ---------------------------------------------------------------------------


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>
