3. Problem description:

Mailman is a program used to help manage email discussion lists.

A flaw was found in Mailman. A remote attacker could spoof messages in
the error log, and possibly trick the administrator into visiting malicious
URLs via a carriage return/line feed sequence in the URI. (CVE-2006-4624)

As well, these updated packages fix the following bugs:

* canceling a subscription on the confirm subscription request page
caused mailman to crash.

* editing the sender filter caused all spam filter rules to be deleted.

* the migrate-fhs script was not included.

* the mailman init script returned a zero (success) exit code even when
an incorrect command was given. For example, the "mailman foo" command
returned a zero exit code. In these updated packages the mailmain init
script returns the correct exit codes.

Users of Mailman are advised to upgrade to these updated packages, which
resolve these issues.

4. Solution:

Before applying this update, make sure that all previously-released
