"--

* It was found that mailman did not sanitize the list name before
passing it to certain MTAs. A local attacker could use this flaw to
execute arbitrary code as the user running mailman. (CVE-2015-2775)

* Previously, it was impossible to configure Mailman in a way that
Domain-based Message Authentication, Reporting & Conformance
(DMARC) would recognize Sender alignment for Domain Key Identified
Mail (DKIM) signatures. Consequently, Mailman list subscribers that
belonged to a mail server with a 'reject' policy for DMARC, such as
yahoo.com or AOL.com, were unable to receive Mailman forwarded
messages from senders residing in any domain that provided DKIM
signatures. With this update, domains with a 'reject' DMARC policy are
recognized correctly, and Mailman list administrators are able to
configure the way these messages are handled. As a result, after a
proper configuration, subscribers now correctly receive Mailman
forwarded messages in this scenario. (BZ#1229288)

* Previously, the /etc/mailman file had incorrectly set permissions,
which in some cases caused removing Mailman lists to fail with a
''NoneType' object has no attribute 'close'' message. With this
update, the permissions value for /etc/mailman is correctly set to
2775 instead of 0755, and removing Mailman lists now works as
expected. (BZ#1229307)

* Prior to this update, the mailman utility incorrectly installed the
tmpfiles configuration in the /etc/tmpfiles.d/ directory. As a
consequence, changes made to mailman tmpfiles configuration were
overwritten if the mailman packages were reinstalled or updated. The
mailman utility now installs the tmpfiles configuration in the
/usr/lib/tmpfiles.d/ directory, and changes made to them by the user
are preserved on reinstall or update. (BZ#1229306)

All mailman users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues."
