Regression ACL & namespace prefix
by Michal Hlavinka 28 Mar '19

28 Mar '19

Hi tl;dr: Seems that for Global ACL directory, namespace prefix is not part of the path, when looking for acl file. Long version: We're planning to update dovecot in next os update to 2.2.36 and while going through regression testing, we found a problem with ACL configuration combined with namespace. Test uses "Global ACL directory" configuration. Relevant configuration part: mail_location = maildir:~/Maildir namespace inbox { hidden = no inbox = yes list = yes location = prefix = separator = / } namespace { hidden = no list = yes location = maildir:/var/mail/pub prefix = pub/ separator = / type = public } mail_plugins = acl protocol imap { mail_plugins = $mail_plugins acl imap_acl } plugin { acl = vfile:/etc/dovecot/global-acls } ACL config file is stored at: /etc/dovecot/global-acls/pub/.DEFAULT when trying to examine "pub", it is denied: fetchmail: IMAP> A0005 EXAMINE "pub" fetchmail: IMAP< A0005 NO Mailbox doesn't exist: pub (0.001 + 0.000 secs). # doveadm acl debug -u d2 pub doveadm(d2): Info: Mailbox '' is in namespace 'pub/' doveadm(d2): Info: Mailbox path: /var/mail/pub doveadm(d2): Info: All message flags are shared across users in mailbox doveadm(d2): Info: User d2 has no rights for mailbox doveadm(d2): Error: User d2 is missing 'lookup' right doveadm(d2): Info: Mailbox pub is NOT visible in LIST because it did not find acl file: imap(d2): Debug: Namespace : type=public, prefix=pub/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/var/mail/pub imap(d2): Debug: maildir++: root=/var/mail/pub, index=, indexpvt=, control=, inbox=, alt= imap(d2): Debug: acl: initializing backend with data: vfile:/etc/dovecot/global-acls imap(d2): Debug: acl: acl username = d2 imap(d2): Debug: acl: owner = 0 imap(d2): Debug: acl vfile: Global ACL legacy directory: /etc/dovecot/global-acls imap(d2): Debug: pub: Mailbox opened because: EXAMINE imap(d2): Debug: acl vfile: file /etc/dovecot/global-acls//.DEFAULT not found imap(d2): Debug: acl vfile: file /var/mail/pub/dovecot-acl not found see it's looking for: /etc/dovecot/global-acls//.DEFAULT instead of /etc/dovecot/global-acls/pub/.DEFAULT Checking with documentation https://wiki.dovecot.org/ACL it seems that prefix should still be part of the path, as it was before: """The filenames must start with namespace prefix (if it has one). For example with namespace prefix=INBOX/ containing mailbox "foo" use /etc/dovecot/acls/INBOX/foo.""" Just for comparison, previous version (2.2.10) would work fine: imap(d2): Debug: Namespace : type=public, prefix=pub/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/var/mail/pub imap(d2): Debug: maildir++: root=/var/mail/pub, index=, indexpvt=, control=, inbox=, alt= imap(d2): Debug: acl: initializing backend with data: vfile:/etc/dovecot/global-acls imap(d2): Debug: acl: acl username = d2 imap(d2): Debug: acl: owner = 0 imap(d2): Debug: acl vfile: Global ACL directory: /etc/dovecot/global-acls imap(d2): Debug: acl vfile: reading file /etc/dovecot/global-acls/pub/.DEFAULT imap(d2): Debug: acl vfile: file /var/mail/pub/dovecot-acl not found I've localized problem to: src/plugins/acl/acl-backend-vfile.c: acl_backend_vfile_object_init(...) and change from: vname = mailbox_list_get_vname(_backend->list, name); to: vname = *name == '\0' ? "" : mailbox_list_get_vname(_backend->list, name); that happened quite time ago during bigger acl changes and I don't know why exactly this line was changed previously. Anyway, reverting this line alone fixes the problem and while testing both per-mailbox ACL vfile and Global ACL file, reverting this did not affect them.

CVE-2019-7524 backport patch for 2.2.33.2
by Gerald Galster 28 Mar '19

28 Mar '19

Hello Aki, I'm currently stuck with 2.2.33.2 as 2.2.36 still duplicates mails after pop3 deletion on a two node dsync cluster. Therefore I've created a small patch and it seems only these two files are affected: dovecot-2.2.36.3/src/lib-storage/index/index-pop3-uidl.c dovecot-2.2.36.3/src/plugins/fts/fts-api.c Please correct me if I have missed something. Best regards Gerald

CVE-2019-7524: Buffer overflow when reading extension header from dovecot index files
by Aki Tuomi 28 Mar '19

28 Mar '19

Product: Dovecot Vendor: OX Software GmbH Internal reference: DOV-2964 (Bug ID) Vulnerability type: CWE-120 Vulnerable version: 2.0.14 - 2.3.5 Vulnerable component: fts, pop3-uidl-plugin Report confidence: Confirmed Researcher credits: Found in internal testing Solution status: Fixed by Vendor Fixed version: 2.3.5.1, 2.2.36.3 Vendor notification: 2019-02-05 Solution date: 2019-03-21 Public disclosure: 2019-03-28 CVE reference: CVE-2019-7524 CVSS: 3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C (8.8) Vulnerability Details: When reading FTS or POP3-UIDL header from dovecot index, the input buffer size is not bound, and data is copied to target structure causing stack overflow. Risk: This can be used for local root privilege escalation or executing arbitrary code in dovecot process context. This requires ability to directly modify dovecot indexes. Steps to reproduce: Produce dovecot.index.log entry that creates an FTS header which has more than 12 bytes of data. Trigger dovecot indexer-worker or run doveadm index. Dovecot will crash. Mitigations: Since 2.3.0 dovecot has been compiled with stack smash protection, ASLR, read-only GOT tables and other techniques that make exploiting this bug much harder. Solution: Operators should update to the latest Patch Release. The only workaround is to disable FTS and pop3-uidl plugin. -- Aki Tuomi Open-Xchange Oy

dovecot mailing list stopped delivering mail
by Christian Anthon 28 Mar '19

28 Mar '19

Strangest thing. Since some time Marts 25. I'm no longer receiving mails from the dovecot mailing list server. Mails from other sources are behaving fine. Instead I'm just seing Mar 26 08:27:54 dna01 postfix/smtpd[107746]: Anonymous TLS connection established from talvi.dovecot.org[94.237.25.159]: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) Mar 26 08:27:54 dna01 postfix/smtpd[107746]: disconnect from talvi.dovecot.org[94.237.25.159] ehlo=1 starttls=1 quit=1 commands=3 And then no more. I tried turning up the postfix verbosity, but I'm none the wiser. I realize that this is probably not a dovecot issue, but anybody with any ideas?

Hello. I have one account with heavy traffic (big mails) and quite often indexes get corrupted. This is dovecot 2.3.5 on local fs (xfs), Linux kernel 4.19.20, glibc 2.28. When corruption happens lmtp and pop3 segfault on accessing it like: > Mar 27 11:13:50 mbox dovecot[22370]: lmtp(24428): Connect from local [0/0] > Mar 27 11:13:50 mbox dovecot[22370]: lmtp(piast_efaktury): pid=<24428> session=<QLacCN5Mm1xsXwAA9fPEKQ>, Error: Index /var/mail/piast_efaktury/dovecot.index: Lost log for seq=13 offset=25648: Missing middle file seq=13 (between 13..4294967295, we have seqs 14,15): .log.2 contains file_seq=14 (initial_mapped=0, reason=Index mapped) > Mar 27 11:13:50 mbox dovecot[22370]: lmtp(piast_efaktury): pid=<24428> session=<QLacCN5Mm1xsXwAA9fPEKQ>, Warning: fscking index file /var/mail/piast_efaktury/dovecot.index > Mar 27 11:13:50 mbox dovecot[22370]: lmtp(piast_efaktury): pid=<24428> session=<QLacCN5Mm1xsXwAA9fPEKQ>, Error: Fixed index file /var/mail/piast_efaktury/dovecot.index: log_file_seq 13 -> 15 > Mar 27 11:13:50 mbox dovecot[22370]: lmtp(piast_efaktury): pid=<24428> session=<QLacCN5Mm1xsXwAA9fPEKQ>, Panic: file mail-transaction-log-file.c: line 105 (mail_transaction_log_file_free): assertion failed: (!file->locked) > Mar 27 11:13:50 mbox dovecot[22370]: lmtp(piast_efaktury): pid=<24428> session=<QLacCN5Mm1xsXwAA9fPEKQ>, Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0xe011b) [0x7f25fc82b11b] -> /usr/lib64/dovecot/libdovecot.so.0(+0xe01b1) [0x7f25fc82b1b1] -> /usr/lib64/dovecot/libdovecot.so.0(+0x4bf56) [0x7f25fc796f56] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x4b17e) [0x7f25fc92f17e] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_transaction_logs_clean+0x5c) [0x7f25fc9e6e3c] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_transaction_log_close+0x34) [0x7f25fc9e6f04] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_transaction_log_move_to_memory+0xed) [0x7f25fc9e709d] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_move_to_memory+0x60) [0x7f25fc9e10b0] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_write+0x1e1) [0x7f25fc9df3a1] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_fsck+0x68a) [0x7f25fc9ca13a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_sync_map+0x5b0) [0x7f25fc9d4090] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_map+0x13b) [0x7f25fc9cc1eb] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0xfcc96) [0x7f25fc9e0c96] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0xfd2a7) [0x7f25fc9e12a7] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_open+0x7a) [0x7f25fc9e13aa] -> /usr/lib64/dovecot/libdovecot-storage.so.0(index_storage_mailbox_open+0xac) [0x7f25fc9bac1c] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x84df9) [0x7f25fc968df9] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x84ecf) [0x7f25fc968ecf] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0xbe11c) [0x7f25fc9a211c] -> /usr/lib64/dovecot/plugins/lib20_zlib_plugin.so(+0x46ee) [0x7f25f8ff86ee] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x5bd56) [0x7f25fc93fd56] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_open+0x4a) [0x7f25fc93ff3a] -> /usr/lib64/dovecot/libdovecot-lda.so.0(mail_deliver_save_open+0x63) [0x7f25fca49cc3] -> /usr/lib64/dovecot/libdovecot-lda.so.0(mail_deliver_save+0xc9) [0x7f25fca49f29] -> /usr/lib64/dovecot/libdovecot-lda.so.0(mail_deliver+0x1c6) [0x7f25fca4a586] -> dovecot/lmtp [local DATA](lmtp_local_data+0x6a1) [0x55e3e295a551] -> dovecot/lmtp [local DATA](cmd_data_continue+0x25d) [0x55e3e295920d] -> /usr/lib64/dovecot/libdovecot.so.0(+0x65737) [0x7f25fc7b0737] > Mar 27 11:13:50 mbox dovecot[22370]: lmtp(piast_efaktury): pid=<24428> session=<QLacCN5Mm1xsXwAA9fPEKQ>, Fatal: master: service(lmtp): child 24428 killed with signal 6 (core dumped) > ~ lmtp backtrace: http://ixion.pld-linux.org/~arekm/dovecot/lmtp-gdb.txt log: http://ixion.pld-linux.org/~arekm/dovecot/lmtp.txt pop3 backtrace: http://ixion.pld-linux.org/~arekm/dovecot/pop3-gdb.txt log: http://ixion.pld-linux.org/~arekm/dovecot/pop3.txt deleting dovecot.index* helps until problem starts again like -

MailCrypt: Encrypted user keys configuration with LDAP & cryptokey generate
by FELINN 28 Mar '19

28 Mar '19

Hi, I try to use the MailCrypt plugin with Floder encryption and encrypted user keys, using LDAP. I use Dovecot 2.2.27 (c0f36b0) I follow the wiki: https://wiki2.dovecot.org/Plugins/MailCrypt doveconf -n and dovecot-ldap.conf.ext attached to this message. I well configured slapd to let dovecot's dn query the userPassword (hashed password SSHA). I use fusiondirectory-mail plugin: ------------------------------------------------------------------------ $ ldapsearch -D 'cn=dovecot,ou=dsa,dc=foo,dc=bar' -W -LLL '(&(objectClass=gosaMailAccount)(objectClass=posixAccount)(uid=<user>))' 'userPassword' dn: cn=<user>,ou=people,dc=foo,dc=bar userPassword:: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX ------------------------------------------------------------------------ The problem is that mails still readable and no keys are generated, even if a send a mail to this address, or login through webmail. I wait more than 1h until something happens, Cf: https://dovecot.org/list/dovecot/2018-September/112763.html If I try to generate keys manually I get this error: ------------------------------------------------------------------------ $ doeveadm mailbox cryptokey generate -u <user> doveadm(<user>): Error: mail_crypt_user_generate_keypair(<user>) failed: mail_crypt_require_encrypted_user_key set, cannot generate user keypair without password or key Folder Public ID x ERROR: mail_crypt_require_encrypted_user_key set, cannot generate user keypair without password or key doveadm(<user>): Warning: Timeout leak: 0x7f0c439c0180 (mail-index-alloc-cache.c:240) ------------------------------------------------------------------------ It works with -o plugin/mail_crypt_private_password=<password> of course, but by hand it's not the goal >< I probably miss something, I guess that the part of the wiki about sql and password_query is only for configuration that use SQL for dbuser. Is there similar things to do with LDAP? Thank you very much for your time. -- f00wl FELINN https://felinn.org

Weird things in the mail queue
by Lionel Elie Mamane 27 Mar '19

27 Mar '19

I noticed a mail stuck in my mail queue. dovecot-lda was returning error 64 Invalid parameter given. (EX_USAGE). Weird, weird, weird. After some sleuthing, I found the sender address was FirstLast(a)domain.tld, with a UTF8-encoded Unicode U+FEFF ZERO WIDTH NO-BREAK SPACE character (AKA byte order mark) between "First" and "Last" :) Since that is passed as the -f parameter to dovecot-lda, it was giving the 64 error.
