DESCRIPTION
 Mailman is a mailing list manager.
 This update fixes two security problems and some other issues not
 related to security:
 
 1. Versions prior do 2.0.2 (affects CL<=6.0) have a vulnerability
 which allows a list administrador to obtain the list password of a
 subscriber. This is not a regular security problem because the list
 administrator does not need that password to gain access to a user's
 subscription, but it is quite possible that the user shares this
 password with other services, such as an email account, even though
 the web interface gives a clear warning about this password and how
 it is handled (by default, the password is mailed out every month).
 
 2. Versions prior do 2.0.6 (affects CL<=7.0) have a vulnerability
 which could allow non-authorized users to gain access to the
 administrative interface of a list. For this to happen, the global
 password (located in the data/adm.pw file) has to be empty, which is
 not very likely. If it is empty, the administrative interface will
 accept any password as valid.
 
 3. This update also brings a logrotate configuration file to our
 mailman package. This will regularly rotate the logs in
 /usr/lib/mailman/logs.
 
 4. Version 2.0.5 (affects CL<=7.0) fixed a problem with stale lock
 files which can cause a list to be inaccessible for long periods of
 time until the lock expires or is removed manually.


SOLUTION
 All mailman administrators should upgrade. It is recommended that the
 update be applied while the server is inactive, that is, the web
 interface should be disabled during this period as well as the MTA
 and crond, since many mailman processes are started at different
 times via cron.
