Server searches not working for 1 user only
by Ignacio García 07 Jan '21

07 Jan '21

Hi there I'm using dovecot version 2.3.4.1 precompiled in Debian stretch-backports (with Maildir, and Lucene FTS). Everything seems to be running fine but server searches by one user (precisely me) using roundcube 1.4.8. For all other checked users server searches work fine. My account is not particularly differnt from others, aprox same amount of mail. The only difference with others is that I use/check my mail constantly and from different devices at the same time (roundcube, a couple of instances of Thunderbird and Aquamail for Android always open). I only use IMAP. Googling around I read about deleting cache/index files with Dovecot recreating them automagically, but since I haven't found anything official on the Wiki, before I do something potentially stupid I wanted to confirm with you all for guidance on this Thanks so much in advance Ignacio

CVE-2020-24386: IMAP hibernation allows accessing other peoples mail
by Aki Tuomi 07 Jan '21

07 Jan '21

Open-Xchange Security Advisory 2021-01-04 Product: Dovecot Vendor: OX Software GmbH Internal reference: DOP-2009 (Bug ID) Vulnerability type: CWE-150: Improper Neutralization of Escape, Meta, or Control Sequences Vulnerable version: 2.2.26-2.3.11.3 Vulnerable component: imap Report confidence: Confirmed Solution status: Fixed by Vendor Fixed version: 2.3.13 Vendor notification: 2020-08-17 Solution date: 2020-08-27 Public disclosure: 2021-01-04 CVE reference: CVE-2020-24386 CVSS: 8.2 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N) Vulnerability Details: When imap hibernation is active, an attacker can cause Dovecot to discover file system directory structure and access other users' emails using specially crafted command. The attacker must have valid credentials to access the mail server. Risk: Attacker can access other users' emails and filesystem information. Workaround: Operators can choose to disable IMAP hibernation. IMAP hibernation is not on by default. To ensure imap hibernation is disabled, make sure imap_hibernate_timeout is set to 0 or unset. Solution: Operators should update to 2.3.13 or later version.

systemd-homed
by Yilin Wei 07 Jan '21

07 Jan '21

Hi, I’ve been looking into a problem with a local dovecot setup with ~systemd-homed~ and uses PAM authentication. To give a brief overview, ~systemd-homed~ mounts the users home directory upon particular authencation calls (which is configurable through ~/etc/pam.d~). Dovecot currently supports PAM authentication perfectly fine — the problem comes when a system has systemd-homed. This is because the session is created and deleted immediately afterwards [1]. This is a problem because if the server isn’t busy, systemd-homed can run it’s cleanup which causes the home directory to be unavailable once again [2]. To support this properly, ideally the whole of the imap/pop3/lda session needs to happen before the deletion of the session. Does the imap session happen within a ~verify_plain~ [3] call? If not, are there any other authentication backends which currently need to keep a live token?

Pigeonhole v0.5.13 released
by Aki Tuomi 06 Jan '21

06 Jan '21

We are pleased to release pigeonhole 0.5.13. You can download it from locations below: https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.13.t… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.13.t… Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Aki Tuomi Open-Xchange oy --- - duplicate: The test was handled badly in a multiscript (sieve_before, sieve_after) scenario in which an earlier script in the sequence with a duplicate test succeeded, while a later script caused a runtime failure. In that case, the message is recorded for duplicate tracking, while the message may not actually have been delivered in the end. - editheader: Sieve interpreter entered infinite loop at startup when the "editheader" configuration listed an invalid header name. This problem can only be triggered by the administrator. - relational: The Sieve relational extension can cause a segfault at compile time. This is triggered by invalid script syntax. The segfault happens when this match type is the last argument of the test command. This situation is not possible in a valid script; positional arguments are normally present after that, which would prevent the segfault. - sieve: For some Sieve commands the provided mailbox name is not properly checked for UTF-8 validity, which can cause assert crashes at runtime when an invalid mailbox name is encountered. This can be caused by the user by writing a bad Sieve script involving the affected commands ("mailboxexists", "specialuse_exists"). This can be triggered by the remote sender only when the user has written a Sieve script that passes message content to one of the affected commands. - sieve: Large sequences of 8-bit octets passed to certain Sieve commands that create or modify message headers that allow UTF-8 text (vacation, notify and addheader) can cause the delivery or IMAP process (when IMAPSieve is used) to enter a memory-consuming semi-infinite loop that ends when the process exceeds its memory limits. Logged in users can cause these hangs only for their own processes.

doveadm backup only working once?
by Engelbert Torremans 06 Jan '21

06 Jan '21

All, For the past 2 weeks I have been trying to get dovecot mail backup working between 2 debian 10 machines. Both machines are running the same OS (Debian 10) and configuration wise they are similar (except of course ip addresses, hostnames etc). My "main" machine is called "server" and the 2nd machine is "server2". See below for the dovecot -n output on server2. I created a testuser called synctest on both server1 and server2 and have sent a couple (2) email messages to synctest@server. Those testmessages are now present in /var/mail/synctest mbox file on server1. When trying to create a backup from server->server2 for user synctest I use this command: #doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345 (using something similar from server1 -> server2 like this: #doveadm -D -v backup -f -u synctest tcp:192.168.3.2:12345 has the same results btw) The first attempte appears to be working OK but the the 2nd attempt (nothing was changed on server1 before the 2nd attempt) fails with soemthing like: Error: Couldn't delete mailbox INBOX: Permission denied Before I can get a succesfull backup again I need to do this (on server2): #rm /var/mail/synctest #rm -r ~syncuser/mail/index/INBOX #doveadm mailbox delete -u synctest INBOX (if I don't do the rm /var/mail/synctest before the doveadm mailbox delete command I will also get a: Error: Can't delete mailbox INBOX: Permission denied Anybody any idea what is happening here? Should I enable replicator and/or aggregator?

Pigeonhole v0.5.13 build fails on OS X 10.11.6
by Steve Akerman 06 Jan '21

06 Jan '21

Hi, Dovecot 2.3.13 builds successfully on this old OS X, but pigeonhole v0.5.13fails as below: gcc -DHAVE_CONFIG_H -I. -I../.. -I/usr/local/include/dovecot -I../.. -I../../src/lib-managesieve -fPIE -DPIE -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wno-duplicate-decl-specifier -Wstrict-aliasing=2 -fstack-protector-strong -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -I../.. -MT managesieve_login-client.o -MD -MP -MF .deps/managesieve_login-client.Tpo -c -o managesieve_login-client.o `test -f 'client.c' || echo './'`client.c In file included from client.c:23: ./managesieve-proxy.h:8:15: warning: declaration of 'enum login_proxy_failure_type' will not be visible outside of this function [-Wvisibility] enum login_proxy_failure_type type, ^ client.c:518:3: error: field designator 'proxy_failed' does not refer to any field in type 'struct client_vfuncs' .proxy_failed = managesieve_proxy_failed, ^ 1 warning and 1 error generated. make: *** [managesieve_login-client.o] Error 1 This appears to be related to the change from manage sieve_proxy_ error to manage sieve_proxy_failed. Pigeonhole v0.5.11 builds without problem on the same machine. The warning appears to be related to the lack of a declaration, but I am no expert. The error I have no idea!!! Is this related to my old compiler, or is there an issue here? Can anyone propose a workaround, as I would like to use Dovecot 2.3.13, but will get version mismatch errors if I do not upgrade pigeonhole. Thanks in advance

Hi! Since Ubuntu 20.04 LTS is nowadays available, we have dropped 16.04 support from 2.3.13 as per policy of supporting two latest releases of operating system. Dovecot 2.3.11.3 is latest version we provide packages for 16.04. Please find Ubuntu 20.04 packages at https://repo.dovecot.org/ Kind regards, Aki Tuomi Open-Xchange oy
