Release: 20050224
Obsoletes: none

None.

Problem description

A directory traversal problem was found in the archive handling of the mailman list manager. This allowed a remote attacker with access to a mailarchive on the machine to read any file readable by the mailman cgi script, including the mailman config database with plaintext passwords, mailinglist archives of closed lists, or any worldreadable file on the system.
This issue has been assigned the Mitre CVE ID CAN-2005-0202.

Solution

Please install the updates provided at the location noted below.

Installation notes

This update is provided as an RPM package that can easily be installed onto a running system by using this command:
rpm -Fvh mailman.rpm
Note 1: The last security update introduced a new dependency on the mailman package. Please make sure that the "python-xml" RPM is installed, otherwise mailman will not work correctly.
Note 2: After installing the upgraded packages, please make sure that your mailinglist config databases have not been retrieved by attackers.
You can do so by checking for patterns like ".....///" in your webservers access logs.
If this is the case:
  • Reset all user passwords. The last security update includes a new "change_member_pw" script which can do that easily.
  • Change the mailinglist admin password.
  • Optionally: Look for members which should not be in the list
