fetchmail: Update to 6.1.25
upstream changes:
-----------------
fetchmail-6.4.25 (released 2021-12-10, 31653 LoC):
# BREAKING CHANGES:
* Since distributions continue patching for LibreSSL use, which cannot be
linked legally, block out LibreSSL in configure.ac and socket.c, and
refer to COPYING, unless on OpenBSD (which ships it in the base system).
OpenSSL and wolfSSL 5 can be used. SSL-related documentation was updated, do
re-read COPYING, INSTALL, README, README.packaging, README.SSL.
* Bump OpenSSL version requirement to 1.0.2f in order to safely remove
the obsolete OpenSSL flag SSL_OP_SINGLE_DH_USE. This blocks out 1.0.2e and
older 1.0.2 versions. 1.0.2f was a security fix release, and 1.0.2u is
publicly available from https://www.openssl.org/source/old/1.0.2/
* Some of the configure.ac fiddling MIGHT have broken cross-compilation
again. The maintainer does not test cross-compiling fetchmail; if you
have difficulties, try setting PKG_CONFIG_LIBDIR to the pkg-config path
containing your target/host libraries, or see if --with-ssl-prefix or
--with-wolfssl-prefix, or overriding LDFLAGS/LIBS/CPPFLAGS, can help.
Feedback solicited on compliant systems that are before end-of-life.
# BUG FIXES:
* 6.4.24's workaround for OpenSSL 1.0.2's X509_V_FLAG_TRUSTED_FIRST flag
contained a typo and would not kick in properly.
* Library and/or rpath setting from configure.ac was fixed.
# ADDITIONS:
* Added an example systemd unit file and instructions to contrib/systemd/
which runs fetchmail as a daemon with 5-minute poll intervals.
Courteously contributed by Barak A. Pearlmutter, Debian Bug#981464.
* fetchmail can now be used with wolfSSL 5's OpenSSL compatibility layer,
see INSTALL and README.SSL. This is considered experimental.
Feedback solicited.
# CHANGES:
* The getstats.py dist-tool now counts lines of .ac and .am files.
* ./configure --with-ssl now supports pkg-config module names, too. See INSTALL.

fetchmail-6.4.24 (released 2021-11-20, 30218 LoC):
# OPENSSL AND LICENSING NOTE:
> see fetchmail-6.4.22 below, and the file COPYING.
Note that distribution of packages linked with LibreSSL is not feasible
due to a missing GPLv2 clause 2(b) exception.
# COMPATIBILITY:
* Bison 3.8 dropped yytoknum altogether, breaking compilation due to a
warning workaround. Remove the cast of yytoknum to void. This may cause
a compiler warning to reappear with older Bison versions.
* OpenSSL 1.0.2: Workaround for systems that keep the expired DST Root CA X3
certificate in its trust store because OpenSSL by default prefers the
untrusted certificate and fails. Fetchmail now sets the
X509_V_FLAG_TRUSTED_FIRST flag (on OpenSSL 1.0.2 only).
This is workaround #2 from the OpenSSL Blog. For details, see both:
https://www.openssl.org/blog/blog/2021/09/13/LetsEncryptRootCertExpire/
https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/
NOTE: OpenSSL 1.0.2 is end of life, it is assumed that the OpenSSL library
is kept up to date by a distributor or via OpenSSL support contract.
Where this is not the case, please upgrade to a supported OpenSSL version.
# DOCUMENTATION:

igor. Some more revisions were made for clarity.

--------------------------------------------------------------------------------
fetchmail-6.4.23 (released 2021-10-31, 30206 LoC):
# USABILITY:
* For common ssh-based IMAP PREAUTH setups (i. e. those that use a plugin
- no matter its contents - and that set auth ssh), change the STARTTLS
error message to suggest sslproto '' instead.
This is a commonly reported issue after the CVE-2021-39272 fix in 6.4.22.
Fixes Redhat Bugzilla 2008160. Fixes GitLab #39.

--------------------------------------------------------------------------------
fetchmail-6.4.22 (released 2021-09-13, 30201 LoC):
# OPENSSL AND LICENSING NOTE:
* fetchmail 6.4.22 is compatible with OpenSSL 1.1.1 and 3.0.0.
OpenSSL's licensing changed between these releases from dual OpenSSL/SSLeay
license to Apache License v2.0, which is considered incompatible with GPL v2
by the FSF. For implications and details, see the file COPYING.
# SECURITY FIXES:
* CVE-2021-39272: fetchmail-SA-2021-02: On IMAP connections, without --ssl and
with nonempty --sslproto, meaning that fetchmail is to enforce TLS, and when
the server or an attacker sends a PREAUTH greeting, fetchmail used to continue
an unencrypted connection. Now, log the error and abort the connection.
--Recommendation for servers that support SSL/TLS-wrapped or \
"implicit" mode on
a dedicated port (default 993): use --ssl, or the ssl user option in an rcfile.
--Reported by: Andrew C. Aitchison, based on the USENIX Security 21 paper "Why
TLS is better without STARTTLS - A Security Analysis of STARTTLS in the Email
Context" by Damian Poddebniak, Fabian Ising, Hanno Böck, and Sebastian
Schinzel. The paper did not mention fetchmail.
* On IMAP and POP3 connections, --auth ssh no longer prevents STARTTLS
negotiation.
* On IMAP connections, fetchmail does not permit overriding a server-side
LOGINDISABLED with --auth password any more.
* On POP3 connections, the possibility for RPA authentication (by probing with
an AUTH command without arguments) no longer prevents STARTTLS negotiation.
* For POP3 connections, only attempt RPA if the authentication type is \
"any".
# BUG FIXES:
* On IMAP connections, when AUTHENTICATE EXTERNAL fails and we have received the
tagged (= final) response, do not send "*".
* On IMAP connections, AUTHENTICATE EXTERNAL without username will properly send
a "=" for protocol compliance.
* On IMAP connections, AUTHENTICATE EXTERNAL will now check if the server
advertised SASL-IR (RFC-4959) support and otherwise refuse (fetchmail <= 6.4
has not supported and does not support the separate challenge/response with
command continuation)
* On IMAP connections, when --auth external is requested but not advertised by
the server, log a proper error message.
* Fetchmail no longer crashes when attempting a connection with --plugin \
"" or
--plugout "".
* Fetchmail no longer leaks memory when processing the arguments of --plugin or
--plugout on connections.
* On POP3 connections, the CAPAbilities parser is now caseblind.
* Fix segfault on configurations with "defaults ... no envelope". \
Reported by
Bjørn Mork. Fixes Debian Bug#992400. This is a regression in fetchmail 6.4.3
and happened when plugging memory leaks, which did not account for that the
envelope parameter is special when set as "no envelope". The \
segfault happens
in a constant strlen(-1), triggered by trusted local input => no vulnerability.
* Fix program abort (SIGABRT) with "internal error" when invalid \
sslproto is
given with OpenSSL 1.1.0 API compatible SSL implementations.
# CHANGES:
* IMAP: When fetchmail is in not-authenticated state and the server volunteers
CAPABILITY information, use it and do not re-probe. (After STARTTLS, fetchmail
must and will re-probe explicitly.)
* For typical POP3/IMAP ports 110, 143, 993, 995, if port and --ssl option
do not match, emit a warning and continue. Closes Gitlab #31.
(cherry-picked from 6.5 beta branch "legacy_6x")
* fetchmail.man and README.SSL were updated in line with RFC-8314/8996/8997
recommendations to prefer Implicit TLS (--ssl/ssl) and TLS v1.2 or newer,
placing --sslproto tls1.2+ more prominently.
The defaults shall not change between 6.4.X releases for compatibility.

Log message:
fetchmail: Update to 6.4.19
upstream changes:
-----------------
fetchmail-6.4.19 (released 2021-04-24, 30026 LoC):
# CHANGE:
* fetchmailconf: properly catch and report option parsing errors
# BUG FIX:
* LMTP: do not try to validate the last component of a UNIX-domain LMTP socket
as though it were a TCP port. Reported by Christoph Heitkamp, Gitlab issue #33.
# TRANSLATION UPDATE:
This fine person has contributed an updated translation:
* sr: Мирослав Николић (Miroslav Nikolić) [Serbian]
--------------------------------------------------------------------------------
fetchmail-6.4.18 (released 2021-03-27, 30011 LoC):
# REGRESSION FIX:
* fetchmailconf: fetchmail 6.4.16 added --sslcertfile to the configuration dump,
but fetchmailconf support was incomplete in Git 7349f124 and it could not
parse sslcertfile, thus the user settings editor came up empty with console
errors printed. Fix configuration parser in fetchmailconf.
# ROBUSTNESS FIXES:
* fetchmailconf: do not require fetchmail for -V. do not require Tk (Tkinter)
for -d option. This is to fail more gracefully on incomplete installs.
* TLS code: remove OPENSSL_NO_DEPRECATED macros to avoid portability issues
with OpenSSL v3 - these are for development purposes, not production.
* TLS futureproofing: use SSL_use_PrivateKey_file instead of
SSL_use_RSAPrivateKey_file, the latter will be deprecated with OpenSSL v3,
and the user's key file might be something else than RSA.
# TRANSLATION UPDATE:
This fine person has contributed an updated translation:
* fi: Lauri Nurmi [Finnish]
--------------------------------------------------------------------------------
fetchmail-6.4.17 (released 2021-03-07, 29998 LoC):
# BUG FIXES
* IMAP client: it used to leak memory for username and password when trying
the LOGIN (password-based) authentication and encountered a timeout situation.
* dist-tools/getstats.py: also counts lines in *.py files, shown above.
# CHANGES
* fetchmail.man: now mentions that you may need to add --ssl when specifying
a TLS-wrapped port.
* fetchmailconf: --version (-V) now prints the Python version in use.
# TRANSLATION UPDATE:
This fine person has contributed an updated translation:
* ja: Takeshi Hamasaki [Japanese]
--------------------------------------------------------------------------------
fetchmail-6.4.16 (released 2021-02-08, 27707 LoC):
# BUG FIXES
* fetchmail's --configdump, and fetchmailconf, lacked support for the
sslcertfile option. --configdump support added by Earl Chew,
Gitlab issue #25, merge request !28.
* fetchmail's manual page was never updated to reflect 6.2.5's change about the
duplicate-killer code for multidrop mode, which read
"* Dup-killer code now keys on an MD5 hash of the raw headers."
...instead of just the Message-ID. [commit 9dd8400, 2003-10-10 by esr]
The manual page was now updated accordingly and documents
historic behaviour:
start to 5.0.7 no duplicate suppression;
5.0.8 to 6.2.4 duplicate suppression only by Message-ID;
6.2.5 to 6.4.X duplicate suppression by entire raw header.
Manpage bug found by Julian Bane debugging "duplicate message" behaviour.
* ./configure no longer runs AC_LIB_LINKFLAGS (how to link) checks
when called --without-ssl
# FEATURES
* fetchmail --version [fetchmail -V] now queries and prints the SSL/TLS
library's "SSL default trusted certificate" file or directory (mind \
the word
"default"), where the OpenSSL-compatible TLS implementation will look for
trusted root, meaning certification authority (CA), certificates.
NOTE 1: watch the output carefully if the line prints the defaults
or the configured path (without "default").
NOTE 2: SSL_CERT_DIR and SSL_CERT_FILE are documented environment variables
for OpenSSL 1.1.1 to override the *default* locations (those compiled into
OpenSSL or possibly in its configuration file).
This was added when Gene Heskett was debugging his setup and the
information "where does OpenSSL look" was missing.
* fetchmail --version now prints version of the OpenSSL library that
it was compiled against, and that it is using at runtime, and also
the OPENSSL_DIR and OPENSSL_ENGINES_DIR (if available).
