---------------------------------------------------------------------
Fedora Legacy Update Advisory

Synopsis: Updated mailman package fixes security issue
Advisory ID: FLSA:152895
Issue date: 2005-07-10
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CAN-2005-0202
---------------------------------------------------------------------


---------------------------------------------------------------------
1. Topic:

Updated mailman packages that correct a mailman security issue are now available.

Mailman is software to help manage email discussion lists, much like Majordomo and Smartmail.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386

3. Problem description:

A flaw in the true_path function of Mailman was discovered. A remote attacker who is a member of a private mailman list could use a carefully crafted URL and gain access to arbitrary files on the server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0202 to this issue.

Note: Mailman installations running on Apache 2.0-based servers are not vulnerable to this issue.

Users of mailman should update to these erratum packages that contain a patch and are not vulnerable to this issue.

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.
