3. Problem description:

Mailman is software to help manage email discussion lists.

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 that all previously-released
errata relevant to your system have been applied.  Use Red Hat
