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

JH/02 Bug 2587: Fix pam expansion condition.  Tainted values are commonly used
      as arguments, so an implementation trying to copy these into a local
      buffer was taking a taint-enforcement trap.  Fix by using dynamically
      created buffers.  Similar fix for radius expansion condition.

JH/03 Bug 2586: Fix listcount expansion operator.  Using tainted arguments is
      reasonable, eg. to count headers.  Fix by using dynamically created
      buffers rather than a local.  Do similar fixes for ACL actions "dcc",
      "log_reject_target", "malware" and "spam"; \ 
the arguments are expanded
      so could be handling tainted values.

JH/04 Bug 2590: Fix -bi (newaliases).  A previous code rearrangement had
      broken the (no-op) support for this sendmail command.  Restore it
      to doing nothing, silently, and returning good status.

JH/05 Bug 2593: Fix "vacation" in Exim filter.  Previously, when a \ 
"once"
      record path was given (or the default used) without a leading directory
      path, an error occurred on trying to open it.  Use the transport's working
      directory.

JH/06 Bug 2594: Change the name used for certificate name checks in the smtp
      transport.  Previously it was the name on the DNS A-record; use instead
      the head of the CNAME chain leading there (if there is one).  This seems
      to align better with RFC 6125.

JH/07 Bug 2597: Fix a resource leak.  Using a lookup in obtaining a value for
      smtp_accept_max_per_host allocated resources which were not released
      when the limit was exceeded.  This eventually crashed the daemon.  Fix
      by adding a relase action in that path.

JH/08 Bug 2598: Fix verify ACL condition.  The options for the condition are
      expanded; previously using tainted values was rejected.  Fix by using
      dynamically-created buffers.

JH/10 Bug 2603: Fix coding of string copying to only evaluate arguments once.
      Previously a macro used one argument twice; when called with the
      argument as an expression having side-effects, incorrect operation
      resulted.  Use an inlineable function.

JH/11 Bug 2604: Fix request to cutthrough-deliver when a connection is already
      held open for a verify callout.  Previously this wan not accounted for
      and a corrupt onward SMTP conversation resulted.

JH/13 Fix dsearch "subdir" filter to ignore ".".  Previously \ 
only ".." was
      excluded, not matching the documentation.

JH/14 Bug 2606: Fix a segfault in sqlite lookups.  When no, or a bad, filename
      was given for the sqlite_dbfile a trap resulted.

JH/15 Bug 2620: Fix "spam" ACL condition.  Previously, tainted values \ 
for the
      "name" argument resulted in a trap.  There is no reason to \ 
disallow such;
      this was a coding error.

JH/16 Bug 2615: Fix pause during message reception, on systems that have been
      suspended/resumed.  The Linux CLOCK_MONOTONIC does not account for time
      spent suspended, ignoring the Posix definition.  Previously we assumed
      it did and a constant offset from real time could be used as a correction.
      Change to using the same clock source for the start-of-message and the
      post-message next-tick-wait.  Also change to using CLOCK_BOOTTIME if it
      exists, just to get a clock slightly more aligned to reality.

JH/17 Bug 2295: Fix DKIM signing to always semicolon-terminate.  Although the
      RFC says it is optional some validators care.  The missing char was not
      intended but triggered by a line-wrap alignement.  Discovery and fix by
      Guillaume Outters, hacked on by JH.

JH/18 Bug 2617: Fix a taint trap in parse_fix_phrase().  Previously when the
      name being quoted was tainted a trap would be taken.  Fix by using
      dynamicaly created buffers.  The routine could have been called by a
      rewrite with the "h" flag, by using the "-F" \ 
command-line option, or
      by using a "name=" option on a control=submission ACL modifier.

JH/21 Bug 2630: Fix eol-replacement string for the ${readsocket } expansion.
      Previously when a whitespace character was specified it was not inserted
      after removing the newline.

JH/24 Bug 2634: Fix a taint trap seen on NetBSD: the testing coded for
      is_tainted() had an off-by-one error in the overenthusiastic direction.
      Find and fix by Gavan.  Although NetBSD is not a supported platform for
      4.94 this bug could affect other platforms.

JH/21 Bug 2630: Fix eol-replacement string for the ${readsocket } expansion.
      Previously when a whitespace character was specified it was not inserted
      after removing the newline.

JH/22 Bug 2265: Force SNI usage for smtp transport DANE'd connections, to be
      the domain part of the recipient address.  This overrides any tls_sni
      option set, which was previously used.

JH/23 Logging: with the +tls_sni log_selector, do not wrap the received SNI
      in quotes.

JH/26 Bug 2646: fix a memory usage issue in ldap lookups.  Previously, when more
      than one server was defined and depending on the platform memory layout
      details, an internal consistency trap could be hit while walking the list
      of servers.

JH/27 Bug 2648: fix the passing of an authenticator public-name through spool
      files.  The value is used by the authresults expansion item.  Previously
      if this was used in a router or transport, a crash could result.

JH/30 Bug 2677: fix matching of long addresses. Since 4.93 a limit of 256 was
      applied. This resulted, if any header-line rewrite rules were configured,
      in a panic-log trigerrable by sending a message with a long address in
      a header.	Fix by increaing the arbitrary limit to larger than a single
      (dewrapped) 5322 header line maximum size.

JH/31 The ESMTP option name advertised for the SUPPORT_EARLY_PIPE build option
      is changed from X_PIPE_CONNECT to PIPE_CONNECT. This is in line with
      RFC 6648 which deprecates X- options in protocols as a general practice.
      Changeover between the implementations is handled by the mechanisms
      alrready coded.

JH/32 Bug 2599: fix delay of delivery to a local address where there is also
      a remote which uses callout/hold.  Previously the local was queued.

JH/33 Fix a taint trap in the ${listextract } expansion when the source data
      was tainted.

JH/35 Bug 2343: Harden exim_tidydb against corrupt wait- files.

JH/36 Bug 2687: Fix interpretation of multiple ^ chars in a plaintext
      authenticator client_send option.  Previously the next char, after a pair
      was collapsed, was taken verbatim (so ^^^foo became ^^foo; ^^^^foo became
      ^^\x00foo). Fixed to get ^\x00foo and ^^foo respectively to match the
      documentation.  There is still no way to get a leading ^ immediately
      after a NUL (ie. for the password of a PLAIN method authenticator.

JH/39 Bug 2691: fix $local_part_data.  When the matching list element
      referred to a file, bad data was returned.  This likely also affected
      $domain_part_data.

JH/41 Fix daemon SIGHUP on FreeBSD.  Previously, a named socket for IPC was
      left undeleted; the attempt to re-create it then failed - resulting in
      the usual "SIGHUP tp have daemon reload configuration" to not work.
      This affected any platform not supporting "abstract" Unix-domain
      sockets (i.e. not Linux).

JH/42 Bug 2692: Harden against a peer which reneges on a 452 "too many
      recipients" response to RCPT in a later response, with a 250.  The
      previous coding assumed this would not happen, and under PIPELINING
      would result in both lost and duplicate recipients for a message.

JH/43 Bug 2694: Fix weighted distribution of work to multiple spamd servers.
      Previously the weighting was incorrectly applied.  Similar fix for socks
      proxies.  Found and fixed by Heiko Schlichting.

JH/44 Bug 2701: Fix list-expansion of dns_ipv4_lookup.  Previously, it did
      not handle sub-lists included using the +namedlist syntax.  While
      investigating, the same found for dns_trust_aa, dns_again_means_nonexist,
      dnssec_require_domains, dnssec_request_domains, srv_fail_domains,
      mx_fail_domains.

HS/01 Enforce absolute PID file path name.

HS/02 Handle SIGINT as we handle SIGTERM: terminate the Exim process.

PP/01 Add a too-many-bad-recipients guard to the default config's RCPT ACL.

PP/02 Bug 2643: Correct TLS DH constants.
      A missing NUL termination in our code-generation tool had led to some
      incorrect Diffie-Hellman constants in the Exim source.
      Reported by kylon94, code-gen tool fix by Simon Arlott.

PP/03 Impose security length checks on various command-line options.
      Fixes CVE-2020-SPRSS reported by Qualys.

PP/04 Fix Linux security issue CVE-2020-SLCWD and guard against PATH_MAX
      better.  Reported by Qualys.

PP/05 Fix security issue CVE-2020-PFPSN and guard against cmdline invoker
      providing a particularly obnoxious sender full name.
      Reported by Qualys.

PP/06 Fix CVE-2020-28016 (PFPZA): Heap out-of-bounds write in parse_fix_phrase()

PP/07 Refuse to allocate too little memory, block negative/zero allocations.
      Security guard.

PP/08 Change default for recipients_max from unlimited to 50,000.

PP/09 Fix security issue with too many recipients on a message (to remove a
      known security problem if someone does set recipients_max to unlimited,
      or if local additions add to the recipient list).
      Fixes CVE-2020-RCPTL reported by Qualys.

PP/10 Fix security issue in SMTP verb option parsing
      Fixes CVE-2020-EXOPT reported by Qualys.

PP/11 Fix security issue in BDAT state confusion.
      Ensure we reset known-good where we know we need to not be reading BDAT
      data, as a general case fix, and move the places where we switch to BDAT
      mode until after various protocol state checks.
      Fixes CVE-2020-BDATA reported by Qualys.

HS/03 Die on "/../" in msglog file names

QS/01 Creation of (database) files in $spool_dir: only uid=0 or the uid of
      the Exim runtime user are allowed to create files.

QS/02 PID file creation/deletion: only possible if uid=0 or uid is the Exim
      runtime user.

QS/03 When reading the output from interpreted forward files we do not
      pass the pipe between the parent and the interpreting process to
      executed child processes (if any).

QS/04 Always die if requested from internal logging, even is logging is
      disabled.

Log message:
exim: fix crash on startup if log_buffer is allocated right after taint pool

The check whether a block of memory is tainted erroneously returns true
if the block in question starts the very next byte after a block in the
tainted pool. Depending on the memory allocator, this can cause problems.
For example, on NetBSD/amd64 9.0, this seems to allocate the first tainted
block immediately before log_buffer. This leads to a recursive error in
log_write the first time anything is written to the log, leading to a
segmentation fault when the stack fills up.
