not in 127.0.0.0/8 to help in spotting list domains taken over by a
domain-parking registrar.
+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/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.
+
+PP/01 Fix default prime selection to be consistent.
+ One path used ike23 still, instead of exim.dev.20160529.3; now both
+ execution flows will use the same DH primes (currently
+ exim.dev.20160529.3).
+
+JH/25 OpenSSL: Fix back-compatibility behaviour surrounding tls_certificates
+ option in smtp transport, to match the documentation. Previously
+ verification was not being done in some cases where it should have been.
+
+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/28 Fix spurious logging of select error. Some platforms, notably FreeBSD,
+ have a sufficient incidence of EINTR returns from select that an
+ interaction with other operations done by the main daemon loop exposed
+ a bug in the error-handling. This was benign apart from the log
+ messages.
+
+JH/29 Bug 2675: add outgoing-interface I= element to deferred "==" log lines,
+ for consistency with delivered "=>" and failed "**" lines. While we're
+ there, handle PRX and TFO.
+
+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/34 Fix the placement of a multiple-message delivery marker in the delivery
+ log line. The asterisk is now consistently appended to the remote IP
+ (and port, if given), and will also be provided on defer and fail log
+ lines. Previously it could be placed on the local IP if that was being
+ logged, and was only provided on delivery lines.
+
+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/37 Enforce the expected size, for fixed-size records read from hints-DB
+ files. For bad sizes read, delete the record and whine to paniclog.
+
+JH/38 When logging an AUTH failure, as server, do not include sensitive
+ information. Previously, the credentials would be included if given
+ as part of the AUTH command line and an ACL denied authentidcation.
+
+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/40 The gsasl authenticator now supports caching of the salted password
+ generated by the client-side implementation. This required the addition
+ of a new variable: $auth4.
+
+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 2693: 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.
+
+JH/45 Use a (new) separate store pool-pair for DKIM verify working data.
+ Previously the permanent pool was used, so the sore could not be freed.
+ This meant a connection with many messages would use continually-growing
+ memory.
+
+JH/46 Use an exponentially-increasing block size when malloc'ing store. Do it
+ per-pool so as not to waste too much space. Previously a constant size
+ was used which resulted in O(n^2) behaviour; now we get O(n log n) making
+ DOS attacks harder. The cost is wasted memory use in the larger blocks.
+
+JH/47 Use explicit alloc/free for DNS lookup workspace. This permits using the
+ same space repeatedly, and a smaller process footprint.
+
+JH/48 Use a less bogus-looking filename for a temporary used for DH-parameters
+ for GnuTLS. Previously the name started "%s" which, while not a bug,
+ looked as if if might be one.
+
+JH/49 Bug 2710: when using SOCKS for additional messages after the first (a
+ "continued connection") make the $proxy_* variables available. Previously
+ the information was not passed across the exec() call for subsequent
+ transport executions. This also mean that the log lines for the
+ messages can show the proxy information.
+
+JH/50 Bug 2672: QT elements in log lines, unless disabled, now exclude the
+ receive time. With modern systems the difference is significant.
+ The historical behaviour can be restored by disabling (a new) log_selector
+ "queue_time_exclusive".
+
+JH/51 Taint-check ACL line. Previously, only filenames (for out-of-line ACL
+ content) were specifically tested for. Now, also cover epxansions
+ rerulting in acl names and inline ACL content.
+
+JH/52 Fix ${ip6norm:} operator. Previously, any trailing line text was dropped,
+ making it unusable in complex expressions.
+
+JH/53 Bug 2743: fix immediate-delivery via named queue. Previously this would
+ fail with a taint-check on the spoolfile name, and leave the message
+ queued.
+
+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.
+
+JH/54 DMARC: recent versions of the OpenDMARC library appear to have broken
+ the API; compilation noo longer completes with DMARC support included.
+ This affects 1.4.1-1 on Fedora 33 (1.3.2-3 is functional); and has
+ been reported on other platforms.
+
+JH/55 TLS: as server, reject connections with ALPN indicating non-smtp use.
+
Exim version 4.94
-----------------
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/05 Regard command-line recipients as tainted.
-JH/06 Bug 340: Remove the daemon pid file on exit, whe due to SIGTERM.
+JH/06 Bug 340: Remove the daemon pid file on exit, when 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
"exim -d -bV". Previously only the compile-time version was shown.
JH/12 Bug 2230: Fix cutthrough routing for nonfirst messages in an initiating
- SMTP connection. Previously, when one had more receipients than the
+ SMTP connection. Previously, when one had more recipients than the
first, an abortive onward connection was made. Move to full support for
multiple onward connections in sequence, handling cutthrough connection
for all multi-message initiating connections.
