An update that fixes one vulnerability is now available.

Description:

This update for mailman to version 2.1.27 fixes the following issues:

This security issue was fixed:

- CVE-2018-0618: Additional protections against injecting scripts into
listinfo and error messages pages (bsc#1099510).

These non-security issues were fixed:

- The hash generated when SUBSCRIBE_FORM_SECRET is set could have been the
same as one generated at the same time for a different list and IP
address.
- An option has been added to bin/add_members to issue invitations instead
of immediately adding members.
- A new BLOCK_SPAMHAUS_LISTED_IP_SUBSCRIBE setting has been added to
enable blocking web subscribes from IPv4 addresses listed in Spamhaus
SBL, CSS or XBL. It will work with IPv6 addresses if Python's
py2-ipaddress module is installed. The module can be installed via pip
if not included in your Python.
- Mailman has a new 'security' log and logs authentication failures
to the
various web CGI functions. The logged data include the remote IP and
can be used to automate blocking of IPs with something like fail2ban.
Since Mailman 2.1.14, these have returned an http 401 status and the
information should be logged by the web server, but this new log makes
that more convenient. Also, the 'mischief' log entries for
'hostile
listname' noe include the remote IP if available.
- admin notices of (un)subscribes now may give the source of the action.
This consists of a %(whence)s replacement that has been added to the
admin(un)subscribeack.txt templates. Thanks to Yasuhito FUTATSUKI for
updating the non-English templates and help with internationalizing the
reasons.
- there is a new BLOCK_SPAMHAUS_LISTED_DBL_SUBSCRIBE setting to enable
blocking web subscribes for addresses in domains listed in the Spamhaus
DBL.
