exim exim-html: updated to 4.94

Exim version 4.94
-----------------

JH/01 Avoid costly startup code when not strictly needed.  This reduces time
      for some exim process initialisations.  It does mean that the logging
      of TLS configuration problems is only done for the daemon startup.

JH/02 Early-pipelining support code is now included unless disabled in Makefile.

JH/03 DKIM verification defaults no long accept sha1 hashes, to conform to
      RFC 8301.  They can still be enabled, using the dkim_verify_hashes main
      option.

JH/04 Support CHUNKING from an smtp transport using a transport_filter, when
      DKIM signing is being done.  Previously a transport_filter would always
      disable CHUNKING, falling back to traditional DATA.

JH/05 Regard command-line receipients as tainted.

JH/06 Bug 340: Remove the daemon pid file on exit, whe due to SIGTERM.

JH/07 Bug 2489: Fix crash in the "pam" expansion condition.  It seems that the
      PAM library frees one of the arguments given to it, despite the
      documentation.  Therefore a plain malloc must be used.

JH/08 Bug 2491: Use tainted buffers for the transport smtp context.  Previously
      on-stack buffers were used, resulting in a taint trap when DSN information
      copied from a received message was written into the buffer.

JH/09 Bug 2493: Harden ARC verify against Outlook, whick has been seen to mix
      the ordering of its ARC headers.  This caused a crash.

JH/10 Bug 2492: Use tainted memory for retry record when needed.  Previously when
      a new record was being constructed with information from the peer, a trap
      was taken.

JH/11 Bug 2494: Unset the default for dmarc_tld_file.  Previously a naiive
      installation would get error messages from DMARC verify, when it hit the
      nonexistent file indicated by the default.  Distros wanting DMARC enabled
      should both provide the file and set the option.
      Also enforce no DMARC verification for command-line sourced messages.

JH/12 Fix an uninitialised flag in early-pipelining.  Previously connections
      could, depending on the platform, hang at the STARTTLS response.

JH/13 Bug 2498: Reset a counter used for ARC verify before handling another
      message on a connection.  Previously if one message had ARC headers and
      the following one did not, a crash could result when adding an
      Authentication-Results: header.

JH/14 Bug 2500: Rewind some of the common-coding in string handling between the
      Exim main code and Exim-related utities.  The introduction of taint
      tracking also did many adjustments to string handling.  Since then, eximon
      frequently terminated with an assert failure.

JH/15 When PIPELINING, synch after every hundred or so RCPT commands sent and
      check for 452 responses.  This slightly helps the inefficieny of doing
      a large alias-expansion into a recipient-limited target.  The max_rcpt
      transport option still applies (and at the current default, will override
      the new feature).  The check is done for either cause of synch, and forces
      a fast-retry of all 452'd recipients using a new MAIL FROM on the same
      connection.  The new facility is not tunable at this time.

JH/16 Fix the variables set by the gsasl authenticator.  Previously a pointer to
      library live data was being used, so the results became garbage.  Make
      copies while it is still usable.

JH/17 Logging: when the deliver_time selector ise set, include the DT= field
      on delivery deferred (==) and failed (**) lines (if a delivery was
      attemtped).  Previously it was only on completion (=>) lines.

JH/18 Authentication: the gsasl driver not provides the $authN variables in time
      for the expansion of the server_scram_iter and server_scram_salt options.

WB/01 SPF: DNS lookups for the obsolete SPF RR type done by the libspf2 library
      are now specifically given a NO_DATA response without hitting the system
      resolver.  The library goes on to do the now-standard TXT lookup.
      Use of dnsdb lookups is not affected.

JH/19 Bug 2507: Modules: on handling a dynamic-module (lookups) open failure,
      only retrieve the errormessage once.  Previously two calls to dlerror()
      were used, and the second one (for mainlog/paniclog) retrieved null
      information.

JH/20 Taint checking: disallow use of tainted data for
      - the appendfile transport file and directory options
      - the pipe transport command
      - the autoreply transport file, log and once options
      - file names used by the redirect router (including filter files)
      - named-queue names
      - paths used by single-key lookups
      Previously this was permitted.

JH/21 Bug 2501: Fix init call in the heimdal authenticator.  Previously it
      adjusted the size of a major service buffer; this failed because the
      buffer was in use at the time.  Change to a compile-time increase in the
      buffer size, when this authenticator is compiled into exim.

JH/22 Taint-checking: move to safe-mode taint checking on all platforms.  The
      previous fast-mode was untenable in the face of glibs using mmap to
      support larger malloc requests.

PP/01 Update the openssl_options possible values through OpenSSL 1.1.1c.
      New values supported, if defined on system where compiled:
      allow_no_dhe_kex, cryptopro_tlsext_bug, enable_middlebox_compat,
      no_anti_replay, no_encrypt_then_mac, prioritize_chacha, tlsext_padding

JH/23 Performance improvement in the initial phase of a two-pass queue run.  By
      running a limited number of proceses in parallel, a benefit is gained. The
      amount varies with the platform hardware and load.  The use of the option
      queue_run_in_order means we cannot do this, as ordering becomes
      indeterminate.

JH/24 Bug 2524: fix the cyrus_sasl auth driver gssapi usage.  A previous fix
      had introduced a string-copy (for ensuring NUL-termination) which was not
      appropriate for that case, which can include embedded NUL bytes in the
      block of data.  Investigation showed the copy to actually be needless, the
      data being length-specified.

JH/25 Fix use of concurrent TLS connections under GnuTLS.  When a callout was
      done during a receiving connection, and both used TLS, global info was
      used rather than per-connection info for tracking the state of data
      queued for transmission.  This could result in a connection hang.

JH/26 Fix use of the SIZE parameter on MAIL commands, on continued connections.
      Previously, when delivering serveral messages down a single connection
      only the first would provide a SIZE.  This was due to the size information
      not being properly tracked.

JH/27 Bug 2530: When operating in a timezone with sub-minute offset, such as
      TAI (at 37 seconds currently), pretend to be in UTC for time-related
      expansion and logging.  Previously, spurious values such as a future
      minute could be seen.

JH/28 Bug 2533: Fix expansion of ${tr } item.  When called in some situations
      it could crash from a null-deref.  This could also affect the
      ${addresses: } operator and ${readsock } item.

JH/29 Bug 2537: Fix $mime_part_count.  When a single connection had a non-mime
      message following a mime one, the variable was not reset.

JH/30 When an pipelined-connect fails at the first response, assume incorrect
      cached capability (perhaps the peer reneged?) and immediately retry in
      non-pipelined mode.

JH/31 Fix spurious detection of timeout while writing to transport filter.

JH/32 Bug 2541: Fix segfault on bad cmdline -f (sender) argument.  Previously
      an attempt to copy the string was made before checking it.

JH/33 Fix the dsearch lookup to return an untainted result.  Previously the
      taint of the lookup key was maintained; we now regard the presence in the
      filesystem as sufficient validation.

JH/34 Fix the readsocket expansion to not segfault when an empty "options"
      argument is supplied.

JH/35 The dsearch lookup now requires that the directory is an absolute path.
      Previously this was not checked, and nonempty relative paths made an
      access under Exim's current working directory.

JH/36 Bug 2554: Fix msg:defer event for the hosts_max_try_hardlimit case.
      Previously no event was raised.

JH/37 Bug 2552: Fix the check on spool space during reception to use the SIZE
      parameter supplied by the sender MAIL FROM command.  Previously it was
      ignored, and only the check_spool_space option value for the required
      leeway checked.

JH/38 Fix $dkim_key_length.  This should, after a DKIM verification, present
      the size of the signing public-key.  Previously it was instead giving
      the size of the signature hash.

JH/39 DKIM verification: the RFC 8301 restriction on sizes of RSA keys is now
      the default.  See the (new) dkim_verify_min_keysizes option.

JH/40 Fix a memory-handling bug: when a connection carried multiple messages
      and an ACL use a lookup for checking either the local_part or domain,
      stale data could be accessed.  Ensure that variable references are
      dropped between messages.

JH/41 Bug 2571: Fix SPA authenticator.  Running as a server, an offset supplied
      by the client was not checked as pointing within response data before
      being used.  A malicious client could thus cause an out-of-bounds read and
      possibly gain authentication.  Fix by adding the check.

JH/42 Internationalisation: change the default for downconversion in the smtp
      transport to be "if needed".  Previously it was "as previously set" for
      the message, which usually meant "if needed" for message-submission but
      "no" for everything else.  However, MTAs have been seen using SMTPUTF8
      even when the envelope addresses did not need it, resulting in forwarding
      failures to non-supporting MTAs.  A downconvert in such cases will be
      a no-op on the addresses, merely dropping the use of SMTPUTF8 by the
      transport.  The change does mean that addresses needing conversion will
      be converted when previously a delivery failure would occur.

JH/43 Fix possible long line in DSN.  Previously when a very long SMTP error
      response was received it would be used unchecked in a fail-DSN, violating
      standards on line-length limits.  Truncate if needed.

HS/01 Remove parameters of the link to www.open-spf.org. The linked form
      doesn't work. (Additionally add a new main config option to configure the
      spf_smtp_comment)
