Vulnerability Insight:
This update for mailman to version 2.1.34 fixes the following issues:

- The fix for lp#1859104 can result in ValueError being thrown
on attempts to subscribe to a list. This is fixed and extended to apply
REFUSE_SECOND_PENDING to unsubscription as well. (lp#1878458)

- DMARC mitigation no longer misses if the domain name returned by DNS
contains upper case. (lp#1881035)

- A new WARN_MEMBER_OF_SUBSCRIBE setting can be set to No to prevent
mailbombing of a member of a list with private rosters by repeated
subscribe attempts. (lp#1883017)

- Very long filenames for scrubbed attachments are now truncated.

- A content injection vulnerability via the private login page has been
fixed. CVE-2020-15011 (lp#1877379, bsc#1173369)

- A content injection vulnerability via the options login page has been
discovered and reported by Vishal Singh. CVE-2020-12108 (lp#1873722,

- Archiving workaround for non-ascii in string.lowercase in some Python

setting that can be used to apply dmarc_moderation_action to mail From:
addresses listed

addresses that don't accept external mail From: themselves.

installation in order to determine the maximum length of a legitimate
list name. It does this on every web access and on sites with a very
large number of lists, this can have performance implications. See the
description in for more information.

- Thanks to Ralf Jung there is now the ability to add text based captchas
(aka textchas) to the listinfo subscribe form. See the documentation
for the new CAPTCHA setting in for how to enable this. Also
note that if you have custom listinfo.html templates, you will have to
add a tag to those templates to make this work. This
feature can be used in combination with or instead of the Google
reCAPTCHA feature added in 2.1.26.

- Thanks to Ralf Hildebrandt the web admin Membership Management section
now has a feature to sync the list's membership with a list of email
addresses as with the bin/sync_members command.

- There is a new drop_cc list attribute set from DEFAULT_DROP_CC. This
controls the dropping of addresses from the Cc: header in delivered
messages by the duplicate avoidance ...
