According to the versions of the mailman package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Cross-site scripting vulnerability in Mailman 2.1.26     and earlier allows remote authenticated attackers to     inject arbitrary web script or HTML via unspecified     vectors.(CVE-2018-0618)

  - An issue was discovered in GNU Mailman before 2.1.28. A     crafted URL can cause arbitrary text to be displayed on     a web page from a trusted site.(CVE-2018-13796)

  - /options/mailman in GNU Mailman before 2.1.31 allows     Arbitrary Content Injection.(CVE-2020-12108)

  - GNU Mailman 2.x before 2.1.30 uses the .obj extension     for scrubbed application/octet-stream MIME parts. This     behavior may contribute to XSS attacks against     list-archive visitors, because an HTTP reply from an     archive web server may lack a MIME type, and a web     browser may perform MIME sniffing, conclude that the     MIME type should have been text/html, and execute     JavaScript code.(CVE-2020-12137)

  - GNU Mailman before 2.1.33 allows arbitrary content     injection via the Cgi/private.py private archive login     page.(CVE-2020-15011)

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. (lp#1884456)

  - 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, bsc#1171363)

  - Bounce recognition for a non-compliant Yahoo format is     added.

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

  - Thanks to Jim Popovitch, there is now a     dmarc_moderation_addresses list setting that can be used     to apply dmarc_moderation_action to mail From: addresses     listed or matching listed regexps. This can be used to     modify mail to addresses that don't accept external mail     From: themselves.

  - There is a new MAX_LISTNAME_LENGTH setting. The fix for     lp#1780874 obtains a list of the names of all the all     the lists in the 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 Defaults.py 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 Defaults.py for how to enable this. Also note that if     you have custom listinfo.html templates, you will have     to add a <mm-captcha-ui> 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 process. (lp#1845751)

  - There is a new REFUSE_SECOND_PENDING mm_cfg.py setting     that will cause a second request to subscribe to a list     when there is already a pending confirmation for that     user. This can be set to Yes to prevent mailbombing of a     third-party by repeatedly posting the subscribe form.
    (lp#1859104)

  - Fixed the confirm CGI to catch a rare TypeError on     simultaneous confirmations of the same token.
    (lp#1785854)

  - Scrubbed application/octet-stream MIME parts will now be     given a .bin extension instead of .obj. CVE-2020-12137     (lp#1886117)

  - Added bounce recognition for a non-compliant opensmtpd     DSN with Action: error. (lp#1805137)

  - Corrected and augmented some security log messages.
    (lp#1810098)

  - Implemented use of QRUNNER_SLEEP_TIME for bin/qrunner

    --runner=All. (lp#1818205)

  - Leading/trailing spaces in provided email addresses for     login to private archives and the user options page are     now ignored. (lp#1818872)

  - Fixed the spelling of the --no-restart option for     mailmanctl.

  - Fixed an issue where certain combinations of charset and     invalid characters in a list's description could produce     a List-ID header without angle brackets. (lp#1831321)

  - With the Postfix MTA and virtual domains, mappings for     the site list -bounces and -request addresses in each     virtual domain are now added to data/virtual-mailman     (-owner was done in 2.1.24). (lp#1831777)

  - The paths.py module now extends sys.path with the result     of site.getsitepackages() if available. (lp#1838866)

  - A bug causing a UnicodeDecodeError in preparing to send     the confirmation request message to a new subscriber has     been fixed. (lp#1851442)

  - The SimpleMatch heuristic bounce recognizer has been     improved to not return most invalid email addresses.
    (lp#1859011)
