This updates to the latest version. According to the changelog 0.5.12
was skipped. The changes in this release are required to be compatible
with the latest dovecot release.
Changes:
- 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.
While we already had some test we might as well add the test for that
exact package to the tests attribute set. After all that should be what
(primarily) tests dovecot.
This fixes CVE_2020-24386, CVE-2020-25725 and a bunch of regular bugs
[1].
* CVE-2020-24386: Specially crafted command can cause IMAP hibernate to
allow logged in user to access other people's emails and filesystem
information.
* CVE-2020-25275: Mail delivery / parsing crashed when the 10 000th MIME part was
message/rfc822 (or if parent was multipart/digest). This happened
due to earlier MIME parsing changes for CVE-2020-12100.

Update to latest version & updated the patch file to match with the
lastest verison.
Fixes the following security issue:
* CVE-2019-19722: Mails with group addresses in From or To fields
caused crash in push notification drivers.
There ver very many conflicts, basically all due to
name -> pname+version. Fortunately, almost everything was auto-resolved
by kdiff3, and for now I just fixed up a couple evaluation problems,
as verified by the tarball job. There might be some fallback to these
conflicts, but I believe it should be minimal.
Hydra nixpkgs: ?compare=1538299
Rationale
---------
Currently, tests are hard to discover. For instance, someone updating
`dovecot` might not notice that the interaction of `dovecot` with
`opensmtpd` is handled in the `opensmtpd.nix` test.
And even for someone updating `opensmtpd`, it requires manual work to go
check in `nixos/tests` whether there is actually a test, especially
given not so many packages in `nixpkgs` have tests and this is thus most
of the time useless.
Finally, for the reviewer, it is much easier to check that the “Tested
via one or more NixOS test(s)” has been checked if the file modified
already includes the list of relevant tests.
Implementation
--------------
Currently, this commit only adds the metadata in the package. Each
element of the `meta.tests` attribute is a derivation that, when it
builds successfully, means the test has passed (ie. following the same
convention as NixOS tests).
Future Work
-----------
In the future, the tools could be made aware of this `meta.tests`
attribute, and for instance a `--with-tests` could be added to
`nix-build` so that it also builds all the tests. Or a `--without-tests`
to build without all the tests. @Profpatsch described in his NixCon talk
such systems.
Another thing that would help in the future would be the possibility to
reasonably easily have cross-derivation nix tests without the whole
NixOS VM stack. @7c6f434c already proposed such a system.
This RFC currently handles none of these concerns. Only the addition of
`meta.tests` as metadata to be used by maintainers to remember to run
relevant tests.
Dovecot has its own SASL implementation,
but needs Cyrus SASL's headers to bind to an LDAP server using SASL.
This is useful to avoid the need to manage a dnpass= in dovecot-ldap.conf
by using the Unix socket to authenticate.
This is done with sasl_mech=EXTERNAL in dovecot-ldap.conf, and some olcAccess: with
by dn="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" read
in the slapd's cn=config for the LDAP database queried by dovecot/auth (which runs as root).
Since years I'm not maintaining anything of the list below other
than some updates when I needed them for some reason. Other people
is doing that maintenance on my behalf so I better take me out but
for very few packages. Finally!
