CONECTIVA LINUX SECURITY ANNOUNCEMENT

PACKAGE : mailman
SUMMARY :
DATE : 2001-09-05 17:58:00
ID : CLA-2001:420
RELEVANT
RELEASES : 4.1, 4.2, 5.0, 5.1, 6.0, 7.0

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.
