Description:
An input validation vulnerability was reported in Mailman in 'private.py'. A remote user can access arbitrary files on the target system.
The true_path() function does not properly validate user-supplied input. A remote user that is a member of a private mailman list can submit a specially crafted input value to access files on the system, including the mailman configuration files and passwords.
A demonsration exploit may contain the following string:
"/...../"
Marcus Meissner reported this flaw.

3. Problem description:
The mailman package 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
Network to download and update your packages. To launch the Red Hat
Update Agent, use the following command:
up2date
