Jan. 12, 2020

Public bug reported: Various failed authentications are reported in the security log, but there are issues: 'options' identifies itself as 'private'. 'roster' doesn't report the user if available. 'create' and 'rmlist' don't log authentication failures. ** Affects: mailman Importance: Medium Assignee: Mark Sapiro (msapiro) Status: In Progress -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1810098 Title: Some security log messages have missing or incorrect information To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1810098/+subscriptions

[Bug 1818205] [NEW] qrunner --runners=All blocks one CPU core
by Michael Lutonsky Jan. 12, 2020

Jan. 12, 2020

Public bug reported: When runner qrunner with --runners=All it calls all defined runners in an endless loop[1]. Most of the time the runners have nothing to do and quickly reach the point where they shut down again[2]. Note that this happens before they sleep in self._snooze(), which is intended to prevent a busy-loop. After that, the runners get started again without delay, in an endless loop, eating up a CPU core. As far as I know this should happen in any mailman2.1 setup when using qrunner with --runners=All.

[Bug 1859104] [NEW] It is possible to mailbomb a third party by repeatedly posting the subscribe form.
by Mark Sapiro Jan. 12, 2020

Jan. 12, 2020

Public bug reported: This can be prevented by refusing to pend a subscription when one is already pending, but that means if a subscriber loses or doesn't receive the confirmation request email, she has to wait PENDING_REQUEST_LIFE (default 3 days) before she can request another. It can also be avoided by setting the list's subscribe_policy to Moderate, but that may not be desirable in many cases. Because of these considerations, I will implement the refusal to pend a subscription when one is already pending, but make that depend on a new REFUSE_SECOND_PENDING mm_cfg.py setting. ** Affects: mailman Importance: Medium Status: In Progress -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1859104 Title: It is possible to mailbomb a third party by repeatedly posting the subscribe form.

[Bug 1785854] [NEW] TypeError from confirm CGI.
by Mark Sapiro Jan. 12, 2020

Jan. 12, 2020

Public bug reported: We have seen some massive, robotic subscribes and confirmations. In rare cases a TypeError can be thrown. This occurs because in processing, the CGI script retrieves the pending entry more than once. If the initial retrieval returns None, an appropriate message is returned, but if two clients confirm the same token at the same time, both initial retrievals may succeed, but then subsequent processing locks the list and retrieves the data again. The first client to get there processes the confirmation which removes the token. Then when the list is unlocked, the second client gets None for the pending data and throws TypeError when retrieving things from None. ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1785854 Title: TypeError from confirm CGI.

[Bug 1805137] [NEW] Bounces sent from opensmtpd not parsed
by Cristiano de Paula Costa Jan. 12, 2020

Jan. 12, 2020

Public bug reported: Hi, We have updated our external MTA to use OpenBSD(6.4) and opensmptd. After we updated, mailman started to send "bounce message w/no discernable addresses" messages to us (list admins). It seems that mailman is not able to parse bounce messages sent from opensmtpd. Please check an example of a bounce message from opensmtpd: Hi! This is the MAILER-DAEMON, please DO NOT REPLY to this email. An error has occurred while attempting to deliver a message for the following list of recipients: XXXXXXXXX(a)live.com: 550 5.5.0 Requested action not taken: mailbox unavailable. [VE1EUR02FT047.eop-EUR02.prod.protection.outlook.com] Below is a copy of the original message: We are using mailman 2.1.11 and I could not test the issue on version 2.1.17. But, reading the code, it seem that the problem is still there. We managed to fix the problem by editing the file 'mailman/Mailman/Bouncers/SimpleMatch.py' and including the following lines: 191,194d190 < # opensmtpd < (_c('An error has occurred while attempting to deliver a message for'), < _c('Below is a copy of the original message'), < _c('^\s*(?P<addr>[^\s@]+@[^\s@]+)')), patch follows attached Regards, Cristiano ** Affects: mailman Importance: Undecided Status: New ** Patch added: "SimpleMatch.py.patch" https://bugs.launchpad.net/bugs/1805137/+attachment/5216458/+files/SimpleMa… -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1805137 Title: Bounces sent from opensmtpd not parsed To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1805137/+subscriptions

[Bug 1831321] [NEW] the List-Id field is filled without < and > around the list-id if the description contains unsupported characters
by Florian Schlegel Jan. 12, 2020

Jan. 12, 2020

Public bug reported: According to rfc2919 the List-Id field should be formated like this: list-id-header = "List-ID:" [phrase] "<" list-id ">" CRLF This works as long as description is left blank or contains supported characters. In my case the description was as follows: �ffentliche Supportliste As you can see the umlaut "Ö" got broken while importing the list from an old server. Unfortunately I don't know how the import was done. The field is still present but < and > around the list-id are missing. This is problematic with procmail and other mail filters. ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1831321 Title: the List-Id field is filled without < and > around the list-id if the description contains unsupported characters To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1831321/+subscriptions

[Bug 1845751] [NEW] cc modification due to nodup setting breaks DKIM & thus DMARC
by Ian Kelling Jan. 12, 2020

Jan. 12, 2020

Public bug reported: Keeping DKIM signature intact allows passing DMARC without from munging (I have references all about this if needed). However, mailman modifies the cc header when a subscriber has the nodup setting and someone sends to the list with that subscriber cced. Mailman doesn't email them and removes them from the cc, presumably so for further replies mailman can email them without it being a duplicate and they get all the good mailman headers instead of a plain email from the cc. Anyways, best if Mailman just not modify the cc if we are in the situation where it matters for passing DMARC. The attached patch does that. Note, I'm sending this as an employee of the Free Software Foundation and my copyright is already going to them. ** Affects: mailman Importance: Undecided Status: New ** Patch added: "nodup-dkim.patch" https://bugs.launchpad.net/bugs/1845751/+attachment/5292024/+files/nodup-dk… -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1845751 Title: cc modification due to nodup setting breaks DKIM & thus DMARC To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1845751/+subscriptions
