- Update to 6.4.20: [bsc#1188875, CVE-2021-36386]
* CVE-2021-36386: DoS or information disclosure in some configurations.
When a log message exceeds c. 2 kByte in size, for instance,
with very long header contents, and depending on verbosity
option, fetchmail can crash or misreport each first log message
that requires a buffer reallocation. fetchmail then reallocates
memory and re-runs vsnprintf() without another call to va_start(),
so it reads garbage. The exact impact depends on many factors
around the compiler and operating system configurations used and
the implementation details of the stdarg.h interfaces of the two
functions mentioned before.

- update to 6.4.18:
* 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.
* 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.
* 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.
* 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.

- update to 6.4.16:
* fetchmail's --configdump, and fetchmailconf, lacked support for
the sslcertfile option.
* 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.
* 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).

- update to 6.4.14:
* sr: Мирослав Николић (Miroslav Nikolić) [Serbian]
* Errors about lock file (= pidfile) creation could be lost in daemon
configurations (-d option, or set daemon) when using syslog. Now they are also
logged to syslog. Found verifying a pidfile creation issue on 6.4.12 that was
previously reported by Alex Hall of Automatic Distributors.
* If the lock file cannot be removed (no write permission on directory), try
to truncate it, and if that fails, report error.
* If the pidfile was non-default, fetchmail -q or --quit would malfunction and
claim no other fetchmail were running, because it did not read the
configuration files or merge the command line options, thus it would look for
the PID in the wrong file.

- update to 6.4.12:
# REGRESSION FIX:
* configure: fetchmail 6.4.9 and 6.4.10 would miss checking for TLS v1.2 and
TLS v1.3 support if AC_LIB_LINKFLAGS came up with something such as
/path/to/libssl.so, rather than -lssl. (For instance on FreeBSD)
* configure: fetchmail 6.4.9's configure was unable to pick up OpenSSL
if it wasn't announced by pkg-config, for instance, on FreeBSD

- Update fetchmail.keyring file
- Use %{_prefix}/lib instead of %{_libexecdir}
- update to 6.4.8:
* Add a test program fm_realpath, and a t.realpath script, neither to be
installed. These will test resolution of the current working directory.
* TRANSLATION UPDATES
* Plug memory leaks when parts of the configuration (defaults, rcfile, command
line) override one another.
* fetchmail terminated the placeholder command string too late and included
garbage from the heap at the end of the string. Workaround: don't use place-
holders %h or %p in the --plugin string. Bug added in 6.4.0 when merging
Gitlab merge request !5 in order to fix an input buffer overrun.
Faulty commit 418cda65f752e367fa663fd13884a45fcbc39ddd.
* Fetchmail now checks for errors when trying to read the .idfile
* Fetchmail's error messages that reports that the defaults entry isn't the
first was made more precise. It could be misleading if there was a poll or
skip statement before the defaults.
* Fetchmail documentation was updated to require OpenSSL 1.1.1.
OpenSSL 1.0.2 reached End Of Life status at the end of the year 2019.
Fetchmail will tolerate, but warn about, 1.0.2 for now on the assumption that
distributors backport security fixes as the need arises.
Fetchmail will also warn if another SSL library that is API-compatible
with OpenSSL lacks TLS v1.3 support.
* If the trust anchor is missing, fetchmail refers the user to README.SSL.
* The AC_DECLS(getenv) check was removed, its only user was broken and not
accounting for that AC_DECLS always defines HAVE_DECL_... to 0 or 1, so
fetchmail never declared a missing getenv() symbol (it was testing with
#ifdef). Remove the backup declaration. getenv is mandated by SUSv2 anyways.
* fetchmailconf now supports Python 3 and currently requires the "future"

- Update to 6.4.1 [bsc#1152964]
## REGRESSION FIXES:
* The bug fix Debian Bug#941129 was incomplete and caused
- a regression in the default file locations, so that fetchmail was
no longer able to find its configuration files in some situations.
- a regression under _FORTIFY_SOURCE where PATH_MAX > minimal _POSIX_PATH_MAX.
- Update to 6.4.0
## SECURITY FIXES THAT AFFECT BEHAVIOUR AND MAY REQUIRE RECONFIGURATION
* Fetchmail no longer supports SSLv2.
* Fetchmail no longer attempts to negotiate SSLv3 by default,
even with --sslproto ssl23. Fetchmail can now use SSLv3, or TLSv1.1 or a newer
TLS version, with STLS/STARTTLS (it would previously force TLSv1.0 with
STARTTLS). If the OpenSSL version used at build and run-time supports these
versions, --sslproto ssl3 and --sslproto ssl3+ can be used to re-enable SSLv3.
Doing so is discouraged because the SSLv3 protocol is broken.
While this change is supposed to be compatible with common configurations,
users may have to and are advised to change all explicit --sslproto ssl2
(change to newer protocols required), --sslproto ssl3, --sslproto tls1 to
--sslproto auto, so that they can benefit from TLSv1.1 and TLSv1.2 where
supported by the server.
The --sslproto option now understands the values auto, ssl3+, tls1+, tls1.1,
tls1.1+, tls1.2, tls1.2+, tls1.3, tls1.3+ (case insensitively), see CHANGES
below for details.
* Fetchmail defaults to --sslcertck behaviour. A new option --nosslcertck to
override this has been added, but may be removed in future fetchmail versions
in favour of another configuration option that makes the insecurity in using
this option clearer.
## SECURITY FIXES
* Fetchmail prevents buffer overruns in GSSAPI authentication with user names
beyond c. 6000 characters in length. Reported by Greg Hudson.
