This is the Postfix 3.7 (stable) release.
The stable Postfix release is called postfix-3.7.x where 3=major
release number, 7=minor release number, x=patchlevel. The stable
release never changes except for patches that address bugs or
emergencies. Patches change the patchlevel and the release date.
New features are developed in snapshot releases. These are called
postfix-3.8-yyyymmdd where yyyymmdd is the release date (yyyy=year,
mm=month, dd=day). Patches are never issued for snapshot releases;
instead, a new snapshot is released.
The mail_release_date configuration parameter (format: yyyymmdd)
specifies the release date of a stable release or snapshot release.
If you upgrade from Postfix 3.5 or earlier, read RELEASE_NOTES-3.6
before proceeding.
License change
---------------
This software is distributed with a dual license: in addition to the
historical IBM Public License 1.0, it is now also distributed with the
more recent Eclipse Public License 2.0. Recipients can choose to take
the software under the license of their choice. Those who are more

Bugfix for messages not delivered after "warning: Unexpected record type 'X'
============================================================================
Due to a bug introduced in Postfix 3.7.0, a message could falsely
be flagged as corrupt with "warning: Unexpected record type 'X'".
Such messages were moved to the "corrupt" queue directory, where
they may still be found. See below for instructions to deal with
these falsely flagged messages.
This could happen for messages with 5000 or more recipients, or
with fewer recipients on a busy mail server. The problem was first
reported by Frank Brendel, reproduced by John Alex.
A file in the "corrupt" queue directory may be inspected with the
command "postcat /var/spool/postfix/corrupt/<filename>. If delivery
of the file is still desired, the file can be moved back to
/var/spool/postfix/incoming after updating Postfix and executing
"postfix reload".
Major changes - configuration
-----------------------------
[Feature 20210605] Support to inline the content of small cidr:,
pcre:, and regexp: tables in Postfix parameter values.
Example:
smtpd_forbidden_commands =
CONNECT GET POST regexp:{{/^[^A-Z]/ Thrash}}
This is the new smtpd_forbidden_commands default value. It will
immediately disconnect a remote SMTP client when a command does not
start with a letter (a-z or A-Z).
The basic syntax is:
/etc/postfix/main.cf:
parameter = .. map-type:{ { rule-1 }, { rule-2 } .. } ..
/etc/postfix/master.cf:
.. -o { parameter = .. map-type:{ { rule-1 }, { rule-2 } .. } .. } ..
where map-type is one of cidr, pcre, or regexp.
Postfix ignores whitespace after '{' and before '}', and writes each
rule as one text line to a nameless in-memory file:
in-memory file:
rule-1
rule-2
..
Postfix parses the result as if it is a file in /etc/postfix.
Note: if a rule contains $, specify $$ to keep Postfix from trying
to do $name expansion as it evaluates the parameter value.
Major changes - lmdb support
----------------------------
[Feature 20210605] Overhauled the LMDB client's error handling, and
added integration tests for future-proofing. There are no visible
changes in documented behavior.
Major changes - logging
-----------------------
[Feature 20210815] To make the maillog_file feature more useful,
the postlog(1) command is now set-gid postdrop, so that unprivileged
programs can use it to write logging through the postlogd(8) daemon.
This required hardening the postlog(1) command against privilege
escalation attacks. DO NOT turn on the set-gid bit with older
postlog(1) implementations.
Major changes - pcre2 support
-----------------------------
[Feature 20211127] Support for the pcre2 library (the legacy pcre
library is no longer maintained). The Postfix build procedure
automatically detects if the pcre2 library is installed, and if it
is unavailable, the Postfix build procedure will detect if the
legacy pcre library is installed. See PCRE_README if you need to
build Postfix with a specific library.
Visible differences: some error messages may have a different text,
and the 'X' pattern flag is no longer supported with pcre2.
Major changes - security
------------------------
[Feature 20220102] Postfix programs now randomize the initial state
of in-memory hash tables, to defend against hash collision attacks
involving a large number of attacker-chosen lookup keys. Presently,
the only known opportunity for such attacks involves remote SMTP
client IPv6 addresses in the anvil(8) service. The attack would
require making hundreds of short-lived connections per second from
thousands of different IP addresses, because the anvil(8) service
drops inactive counters after 100s. Other in-memory hash tables
with attacker-chosen lookup keys are by design limited in size. The
fix is cheap, and therefore implemented for all Postfix in-memory
hash tables. Problem reported by Pascal Junod.
[Feature 20211030] The postqueue command now sanitizes non-printable
characters (such as newlines) in strings before they are formatted
as json or as legacy output. These outputs are piped into other
programs that are run by administrative users. This closes a
hypothetical opportunity for privilege escalation.
[Feature 20210815] Updated defense against remote clients or servers
that 'trickle' SMTP or LMTP traffic, based on per-request deadlines
and minimum data rates.
Per-request deadlines:
The new {smtpd,smtp,lmtp}_per_request_deadline parameters replace
{smtpd,smtp,lmtp}_per_record_deadline, with backwards compatible
default settings. This defense is enabled by default in the Postfix
SMTP server in case of overload.
The new smtpd_per_record_deadline parameter limits the combined
time for the Postfix SMTP server to receive a request and to send
a response, while the new {smtp,lmtp}_per_record_deadline parameters
limit the combined time for the Postfix SMTP or LMTP client to send
a request and to receive a response.
Minimum data rates:
The new smtpd_min_data_rate parameter enforces a minimum plaintext
data transfer rate for DATA and BDAT requests, but only when
smtpd_per_record_deadline is enabled. After a read operation transfers
N plaintext bytes (possibly after TLS decryption), and after the
DATA or BDAT request deadline is decreased by the elapsed time of
that read operation, the DATA or BDAT request deadline is increased
by N/smtpd_min_data_rate seconds. However, the deadline is never
increased beyond the smtpd_timeout value. The default minimum data
rate is 500 (bytes/second) but is still subject to change.
The new {smtp,lmtp}_min_data_rate parameters enforce the corresponding
minimum DATA transfer rates for the Postfix SMTP and LMTP client.
Major changes - tls support
---------------------------
[Cleanup 20220121] The new tlsproxy_client_security_level parameter
replaces tlsproxy_client_level, and the new tlsproxy_client_policy_maps
parameter replaces tlsproxy_client_policy. This is for consistent
parameter naming (tlsproxy_client_xxx corresponds to smtp_tls_xxx).
This change was made with backwards-compatible default settings.
[Feature 20210926] Postfix was updated to support OpenSSL 3.0.0 API
features, and to work around OpenSSL 3.0.0 bit-rot (avoid using
deprecated API features).
Other code health
-----------------
[typos] Typo fixes by raf.
[pre-release checks] Added pre-release checks to detect a) new typos
in documentation and source-code comments, b) missing entries in
the postfix-files file (some documentation would not be installed),
c) missing rules in the postlink script (some text would not have
a hyperlink in documentation), and d) missing map-based $parameter
names in the proxy_read_maps default value (the proxymap daemon
would not automatically authorize some proxied maps).
[memory stream] Improved support for memory-based streams made it
possible to inline small cidr:, pcre:, and regexp: maps in Postfix
parameter values, and to eliminate some ad-hoc code that converted
tlsproxy(8) protocol data to or from serialized form.
*************************************************************************
This is the Postfix 3.6 (stable) release.
The stable Postfix release is called postfix-3.6.x where 3=major
release number, 6=minor release number, x=patchlevel. The stable
release never changes except for patches that address bugs or
emergencies. Patches change the patchlevel and the release date.
New features are developed in snapshot releases. These are called
postfix-3.7-yyyymmdd where yyyymmdd is the release date (yyyy=year,
mm=month, dd=day). Patches are never issued for snapshot releases;
instead, a new snapshot is released.
The mail_release_date configuration parameter (format: yyyymmdd)
specifies the release date of a stable release or snapshot release.
If you upgrade from Postfix 3.4 or earlier, read RELEASE_NOTES-3.5
before proceeding.
License change
---------------
This software is distributed with a dual license: in addition to the
historical IBM Public License 1.0, it is now also distributed with the
more recent Eclipse Public License 2.0. Recipients can choose to take
the software under the license of their choice. Those who are more
comfortable with the IPL can continue with that license.
Major changes - internal protocol identification
------------------------------------------------
[Incompat 20200920] Internal protocols have changed. You need to
"postfix stop" before updating, or before backing out to an earlier
release, otherwise long-running daemons (pickup, qmgr, verify, tlsproxy,
postscreen) may fail to communicate with the rest of Postfix, causing
mail delivery delays until Postfix is restarted.
This change does not affect message files in Postfix queue directories,
only the communication between running Postfix programs.
With this change, every Postfix internal service, including the postdrop
command, announces the name of its protocol before doing any other I/O.
Every Postfix client program, including the Postfix sendmail command,
will verify that the protocol name matches what it is supposed to be.
The purpose of this change is to produce better error messages, for
example, when someone configures the discard daemon as a bounce
service in master.cf, or vice versa.
This change may break third-party programs that implement a
Postfix-internal protocol such as qpsmtpd. Such programs have never
been supported. Fortunately, this will be an easy fix: look at the
first data from the cleanup daemon: if it is a protocol announcement,
you're talking to Postfix 3.6 or later. That's the only real change.
Major changes - tls
-------------------
[Incompat 20200705] The minimum supported OpenSSL version is 1.1.1,
which will reach the end of life by 2023-09-11. Postfix 3.6 is
expected to reach the end of support in 2025. Until then, Postfix
will be updated as needed for compatibility with OpenSSL.
The default fingerprint digest has changed from md5 to sha256 (Postfix
3.6 with compatibility_level >= 3.6). With a lower compatibility_level
setting, Postfix defaults to using md5, and logs a warning when a Postfix
configuration specifies no explicit digest type.
Export-grade Diffie-Hellman key exchange is no longer supported,
and the tlsproxy_tls_dh512_param_file parameter is ignored,
[Feature 20200906] The tlstype.pl helper script by Viktor Dukhovni
reports TLS information per message delivery. This processes output
from the collate.pl script. See auxiliary/collate/README.tlstype and
auxiliary/collate/tlstype.pl.
Major changes - compatibility level
-----------------------------------
[Feature 20210109] Starting with Postfix version 3.6, the compatibility
level is "3.6". In future Postfix releases, the compatibility level will
be the Postfix version that introduced the last incompatible change. The
level is formatted as 'major.minor.patch', where 'patch' is usually
omitted and defaults to zero. Earlier compatibility levels are 0, 1 and 2.
This also introduces main.cf and master.cf support for the <=level,
<level, and other operators to compare compatibility levels. With the
standard <=, <, etc. operators, compatibility level 3.10 would be less
than 3.9, which is undesirable.
Major changes - services(5) override
------------------------------------
[Feature 20210418] Postfix no longer uses the services(5) database
to look up the TCP ports for SMTP and LMTP services. Instead, this
information is configured with the new known_tcp_ports configuration
parameter (default: lmtp=24, smtp=25, smtps=submissions=465,
submission=587). When a service is not specified in known_tcp_ports,
Postfix will still query the services(5) database.
Major changes - local_login_sender_maps
---------------------------------------
[Feature 20201025] Fine-grained control over the envelope sender address
for submission with the Postfix sendmail (or postdrop) commands.
The local_login_sender_maps parameter (default: static:*) specifies
a list of lookup tables that are searched by the UNIX login name, and
that return a list of allowed envelope sender patterns separated by
space or comma. The default is backwards-compatible: every user may
specify any sender envelope address.
This feature is enforced by the postdrop command. When no UNIX login
name is available, the postdrop command will prepend "uid:" to the
numerical UID and use that instead.
This feature ignores address extensions in the user-specified
envelope sender address.
Besides the special pattern "*" which allows any sender address,
there are "<>" which matches an empty sender address, and the
"@domain" wildcard pattern. More information about those can be found
in the postconf(5) manpage.
Example:
/etc/postfix/main.cf:
# Allow root and postfix full control, anyone else can only
# send mail as themselves. Use "uid:" followed by the numerical
# UID when the UID has no entry in the UNIX password file.
local_login_sender_maps =
inline:{ { root = *}, { postfix = * } },
pcre:/etc/postfix/login_senders
/etc/postfix/login_senders:
# Allow both the bare username and the user@domain forms.
/(.+)/ $1 $1@example.com
Major changes - order of relay and recipient restrictions
---------------------------------------------------------
[Incompat 20210131] With smtpd_relay_before_recipient_restrictions=yes,
the Postfix SMTP server will evaluate smtpd_relay_restrictions before
smtpd_recipient_restrictions. This is the default behavior with
compatibility_level >= 3.6.
This change makes the implemented behavior consistent with existing
documentation. There is a backwards-compatibility warning that allows
users to freeze historical behavior. See COMPATIBILITY_README for
details.
Major changes - respectful logging
----------------------------------
[Feature 20210220] Postfix version 3.6 deprecates terminology
that implies white is better than black. Instead, Postfix prefers
'allowlist', 'denylist', and variations on those words. This change
affects Postfix documentation, and postscreen parameters and logging.
To keep the old postscreen logging set "respectful_logging = no"
in main.cf.
Noel Jones assisted with the initial transition.
Changes in documentation
------------------------
Postfix documentation was updated to use 'allowlist', 'denylist', etc.
These documentation changes do not affect Postfix behavior.
Changes in parameter names
--------------------------
The following postscreen parameters replace names that contain 'blacklist'
or 'whitelist':
postscreen_allowlist_interfaces
postscreen_denylist_action
postscreen_dnsbl_allowlist_threshold
These new parameters have backwards-compatible default settings
that support the old parameter names, so that the name change should
not affect Postfix behavior. This means that existing management tools
that use the old parameter names should keep working as before.
This compatibility safety net may break when some management tools
use the new parameter names, and some use the old names, such that
different tools will disagree on how Postfix works.
Changes in logging
------------------
The following logging replaces forms that contain 'blacklist' or
'whitelist':
postfix/postscreen[pid]: ALLOWLIST VETO [address]:port
postfix/postscreen[pid]: ALLOWLISTED [address]:port
postfix/postscreen[pid]: DENYLISTED [address]:port
To avoid breaking logfile analysis tools, Postfix keeps logging the old
forms by default, as long as the compatibility_level parameter setting
is less than 3.6, and the respectful_logging parameter is not explicitly
configured. As a reminder, Postfix will log the following:
postfix/postscreen[pid]: Using backwards-compatible default setting
respectful_logging=no for client [address]:port
To keep logging the old form, make the setting "respectful_logging =
no" permanent in main.cf, for example:
# postconf "respectful_logging = no"
# postfix reload
To stop the reminder, configure the respectful_logging parameter to
"yes" or "no", or configure "compatibility_level = 3.6".
Major changes - threaded bounces
--------------------------------
[Feature 20201205] Support for threaded bounces. This allows mail
readers to present a non-delivery, delayed delivery, or successful
delivery notification in the same email thread as the original
message.
Unfortunately, this also makes it easy for users to mistakenly delete
the whole email thread (all related messages), instead of deleting
only the delivery status notification.
To enable, specify "enable_threaded_bounces = yes".
Other changes - smtpd_sasl_mechanism_list
-----------------------------------------
[Feature 20200906] The smtpd_sasl_mechanism_list parameter (default:
!external, static:rest) prevents confusing errors when a SASL backend
announces EXTERNAL support which Postfix does not support.
Other changes - delivery logging
--------------------------------
[Incompat 20200531] Postfix delivery agents now log an explicit record
when delegating delivery to a different Postfix delivery agent.
For example, with "best_mx_transport = local", an SMTP delivery
agent will now log when a recipient will be delivered locally. This
makes the delegating delivery agent visible, where it would otherwise
have remained invisible, which would complicate troubleshooting.
postfix/smtp[pid]: queueid: passing <recipient> to transport=local
This will usually be followed by logging for an actual delivery:
postfix/local[pid]: queueid: to=<recipient>, relay=local, ...
Other examples: the local delivery agent will log a record that it
defers mailbox delivery through mailbox_transport or through
fallback_transport.
Other changes - error logging
-----------------------------
[Incompat 20200531] Postfix programs will now log "Application error"
instead of "Success" or "Unknown error: 0" when an operation fails with
errno == 0, i.e., the error originates from non-kernel code.
Other changes - dns lookups
---------------------------
[Feature 20200509] The threadsafe resolver API (res_nxxx() calls)
is now the default, not because the API is threadsafe, but because
this is the API where new features are being added.
To build old style, build with:
make makefiles CCARGS="-DNO_RES_NCALLS..."
This is the default for systems that are known not to support the
threadsafe resolver API.

6 May 2022: Wouter
- Merge PR #209: IXFR out
This adds IXFR out functionality to NSD. NSD can copy IXFRs from
upstream to downstream clients, or create IXFRs from zonefiles.
The options store-ixfr: yes and create-ixfr: yes can be used to
turn this on. Default is turned off. The options ixfr-number and
ixfr-size can be used to tune the number of IXFR transfers and
total data size stored. This is configured per zone, the IXFRs
are served to the hosts that are allowed to perform zone transfers.
And if TSIG is configured, signed with the same key. The content
is stored to file if a zonefile is configured for the zone, in
the zonefile.ixfr and zonefile.ixfr.2, .. files. They contain
readable text format. The number of IXFRs is num.rixfr in
statistics output, also per zone if per zone statistics are enabled.
If offline, nsd-checkzone -i can create ixfr files.
NSD already supports requesting IXFRs, this addition allows NSD
to serve IXFR transfers to clients.
NSD stops responding with NOTIMPL to IXFR requests, also for zones
that do not have IXFR enabled. The clients gets a full zone reply
or a status reply if the serial is up to date.

using the "in-view" statement, running "rndc freeze"
always reported an "already frozen" error even though
the zone was successfully frozen. [GL #2844]

metadata found in private key files: if a signature for
an RRset generated by the inactive predecessor exists
and does not need to be replaced, no additional
signature is now created for that RRset using the
successor key. This enables dnssec-signzone to gradually
replace RRSIGs during a ZSK rollover. [GL #1551]
This was never relevant on FreeBSD and I don't think it is relevant on
NetBSD either. The FreeBSD change to lift this restriction had the

This restriction was inherited from upstream but is not relevant on FreeBSD.
Furthermore, it hindered the tracing of locking primitive subroutines.
This way they match the mtree and make sense and don't cause editors
to ask to override read-only files when editing them.
Exception: Not sure /etc/bluetooth/protocols makes as much sense to

to change it in both places -- Makefile and mtree.

While here, correctly compare version numbers, correctly handling the

The GTZ version hadn't been updated (there was no real need, since the

For NetBSD/m68k, program header is erroneously readable from core dump,
although a page containing it is missing. This spoils relocation for
the main executable, and debugging with core dumps becomes impossible,
as described in the PR.
In order to avoid this failure, add consistency check for program header;
for NetBSD, 1st entry of program header refers program header itself. If
this is not the case, we should be reading random garbage from core dump.
Yes, this is a kind of the hackest hack. But, unable to debug with core
dump is critical. Therefore, I commit this workaround temporarily until
the real cause is found and fixed.
Note that this is not a recent regression for GDB nor kernel, as
mentioned in the PR. These from netbsd-8 and -9 fail in the same way
without this hack.

there's an extra check that we inherited from FreeBSD that tries to
detect KVA exhaustion on platforms with limited KVA, but the condition
that decided whether to use the extra check was using a FreeBSDism
that doesn't exist on NetBSD, resulting in this check being used on
all platforms. on amd64 systems with lots of memory, this extra check
would result in the ARC thinking that it constantly needed to reclaim memory,
resulting in all the xcall threads running all the time but not doing
anything useful. change this condition so that this extra check for
KVA exhaustion is only used on 32-bit platforms. fixes PR 55707.

Changes since 4.4.2-P1 (New Features)
- Two new OMAPI function calls were added, `dhcpctl_timed_connect()`
and `dhcpctl_timed_wait_for_completion()`. These provide timed
versions of creating a connection and waiting for an operation
to complete.
[GitLab #76]
- The BIND libraries have been updated to the latest version, 9.11.36.
This fixes a number of compilation issues on various systems, including
OpenWRT. Thanks to Philip Prindeville for testing on OpenWRT.
[GitLab #218, #171, #180, #192]
- Support was added for the new DHCPv4 option v6-only-preferred, specified
in RFC 8925. A new reason code, V6ONLY, was added to the client script
and the client Linux script sample was updated.
[GitLab #132]
Changes since 4.4.2-P1 (Bug Fixes)
- Minor corrections were made to allow compilation under gcc 10.
[GitLab #117]
- The logic in dhclient that causes it to decline DHCPv4 leases if the
client script exits abnormally (i.e. crashes) has been corrected.
[GitLab #123]
- The limit on the size of a lease file that can be loaded at startup
is now only enforced on 32-bit systems.
[GitLab #92]
- The PRNG initialization has been improved. It now uses the configure flag
`--with-randomdev=PATH`, which specifies the device from which to read the
initial seed. That is typically `/dev/random` (the default value) or
`/dev/urandom`, but may be specified otherwise on the local system. The old
behavior can be forced by disabling this feature (`--with-randomdev=no`).
If the initialization is disabled or reading from the random device fails,
the previous algorithm (retrieve the last four bytes of hardware addresses
from all network interfaces that have them, and use the current time and
process ID) is used.
[GitLab #197]
- A minor dhclient code fix was made to remove compilation warnings.
[GitLab #190]
- The hard-coded MD5 algorithm name was removed in OMAPI connection logic.
Previously, using any other algorithm via a key-algorithm statement would
allow OMAPI connections to be made, but subsequent actions such as updating
an object would fail.
[GitLab #148]
- The parallel build has been improved. Thanks to Sergei Trofimovich for
the patch. The parallel build is still experimental, as officially the
BIND 9 code does not support the parallel build for libraries.
[GitLab #91]
- Handling of LDAP options (`ldap-gssapi-principal` and `ldap-gssapi-keytab`)
has been improved. This is contributed code that has not been tested by ISC.
Thank you to Petr Mensik and Pavel Zhukov for the patches!
[GitLab !56,!75]
- It is now possible to use `option -g ipaddr` in the dhcrelay to replace the

(2022a comes from ftp://ftp.iana.org/tz/releases/tzdata2022a.tar.gz)
Note that 2022agtz is mechanically derived from 2022a by moving back
zone data from the "backzone" file that had been removed as "redundant"
(because differences to some other zone are all prior to 1970) so that
this pre 1970 data is restored. It isn't necessarily correct in all
cases, but it is usually better than using some other zone's data which
is just as likely to be incorrect for where it applies, and more so elsewhere.
Summary of changes in tzdata2022a (2022-03-15 23:02:01 -0700):
* Palestine will spring forward on 2022-03-27, not 2022-03-26.
* From 1992 through spring 1996, Ukraine's DST transitions were at
02:00 standard time, not at 01:00 UTC.
* Chile's Santiago Mean Time and its LMT precursor have been adjusted
eastward by 1 second to align with past and present law.
* Changes to commentary.
- Serialize updates to lockstat_enabled, lockstat_dev_enabled, and
lockstat_dtrace_enabled with a new __cpu_simple_lock.
- Use xc_barrier to obviate any need for additional membars in
lockstat_event.
- Use atomic_load/store_* for access that might not be serialized by
lockstat_lock or lockstat_enabled_lock.

Release 2.4.5 Fri February 18 2022
Security fixes:
#562 CVE-2022-25235 -- Passing malformed 2- and 3-byte UTF-8
sequences (e.g. from start tag names) to the XML
processing application on top of Expat can cause
arbitrary damage (e.g. code execution) depending
on how invalid UTF-8 is handled inside the XML
processor; validation was not their job but Expat's.
Exploits with code execution are known to exist.
#561 CVE-2022-25236 -- Passing (one or more) namespace separator
characters in "xmlns[:prefix]" attribute values
made Expat send malformed tag names to the XML
processor on top of Expat which can cause
arbitrary damage (e.g. code execution) depending
on such unexpectable cases are handled inside the XML
processor; validation was not their job but Expat's.
Exploits with code execution are known to exist.
#558 CVE-2022-25313 -- Fix stack exhaustion in doctype parsing
that could be triggered by e.g. a 2 megabytes
file with a large number of opening braces.
Expected impact is denial of service or potentially
arbitrary code execution.
#560 CVE-2022-25314 -- Fix integer overflow in function copyString;
only affects the encoding name parameter at parser creation
time which is often hardcoded (rather than user input),
takes a value in the gigabytes to trigger, and a 64-bit
machine. Expected impact is denial of service.
#559 CVE-2022-25315 -- Fix integer overflow in function storeRawNames;
needs input in the gigabytes and a 64-bit machine.
Expected impact is denial of service or potentially
arbitrary code execution.

common and default).
Impact is denial of service or more.
#551 CVE-2022-23990 -- Fix unsigned integer overflow in function
doProlog triggered by large content in element type
declarations when there is an element declaration handler
present (from a prior call to XML_SetElementDeclHandler).
Impact is denial of service or more.
Bug fixes:

Release 2.4.3 Sun January 16 2022
Security fixes:
#531#534 CVE-2021-45960 -- Fix issues with left shifts by >=29 places
resulting in
a) realloc acting as free
b) realloc allocating too few bytes
c) undefined behavior
depending on architecture and precise value
for XML documents with >=2^27+1 prefixed attributes
on a single XML tag a la
"<r xmlns:a='[..]' a:a123='[..]' [..] />"
where XML_ParserCreateNS is used to create the parser
(which needs argument "-n" when running xmlwf).
Impact is denial of service, or more.
#532#538 CVE-2021-46143 (ZDI-CAN-16157) -- Fix integer overflow
on variable m_groupSize in function doProlog leading
to realloc acting as free.
Impact is denial of service or more.
#539 CVE-2022-22822 to CVE-2022-22827 -- Prevent integer overflows
near memory allocation at multiple places. Mitre assigned

Release 2.4.0 Sun May 23 2021
Security fixes:
#34#466#484 CVE-2013-0340/CWE-776 -- Protect against billion laughs attacks
(denial-of-service; flavors targeting CPU time or RAM or both,
leveraging general entities or parameter entities or both)
by tracking and limiting the input amplification factor
(<amplification> := (<direct> + <indirect>) / <direct>).
By conservative default, amplification up to a factor of 100.0
is tolerated and rejection only starts after 8 MiB of output bytes
(=<direct> + <indirect>) have been processed.
The fix adds the following to the API:
- A new error code XML_ERROR_AMPLIFICATION_LIMIT_BREACH to
signals this specific condition.
- Two new API functions ..
- XML_SetBillionLaughsAttackProtectionMaximumAmplification and
- XML_SetBillionLaughsAttackProtectionActivationThreshold
.. to further tighten billion laughs protection parameters
when desired. Please see file "doc/reference.html" for details.
If you ever need to increase the defaults for non-attack XML
payload, please file a bug report with libexpat.
- Two new XML_FEATURE_* constants ..
- that can be queried using the XML_GetFeatureList function, and
- that are shown in "xmlwf -v" output.
- Two new environment variable switches ..
- EXPAT_ACCOUNTING_DEBUG=(0|1|2|3) and
- EXPAT_ENTITY_DEBUG=(0|1)
.. for runtime debugging of accounting and entity processing.
Specific behavior of these values may change in the future.
- Two new command line arguments "-a FACTOR" and "-b BYTES"
for xmlwf to further tighten billion laughs protection
parameters when desired.
If you ever need to increase the defaults for non-attack XML
payload, please file a bug report with libexpat.
Bug fixes:
#332#470 For (non-default) compilation with -DEXPAT_MIN_SIZE=ON (CMake)
or CPPFLAGS=-DXML_MIN_SIZE (GNU Autotools): Fix segfault
for UTF-16 payloads containing CDATA sections.

Release 2.3.0 Thu March 25 2021
Bug fixes:
#438 When calling XML_ParseBuffer without a prior successful call to
XML_GetBuffer as a user, no longer trigger undefined behavior
(by adding an integer to a NULL pointer) but rather return
XML_STATUS_ERROR and set the error code to (new) code
XML_ERROR_NO_BUFFER. Found by UBSan (UndefinedBehaviorSanitizer)
of Clang 11 (but not Clang 9).
#444 xmlwf: Exit status 2 was used for both:
- malformed input files (documented) and
- invalid command-line arguments (undocumented).
The case of invalid command-line arguments now
has its own exit status 4, resolving the ambiguity.
Other changes:
#439 xmlwf: Add argument -k to allow continuing after
non-fatal errors
#439 xmlwf: Add section about exit status to the -h help output
#422#426#447 Windows: Drop support for Visual Studio <=14.0/2015
#434 Windows: CMake: Detect unsupported Visual Studio at
configure time (rather than at compile time)
#382#428 testrunner: Make verbose mode (argument "-v") report
about passed tests, and make default mode report about
failures, as well.
#442 CMake: Call "enable_language(CXX)" prior to tinkering
with CMAKE_CXX_* variables
#448 Document use of libexpat from a CMake-based project
#451 Autotools: Install CMake files as generated by CMake 3.19.6
so that users with "find_package(expat [..] CONFIG [..])"
are served on distributions that are *not* using the CMake
build system inside for libexpat packaging
#436#437 Autotools: Drop obsolescent macro AC_HEADER_STDC
#450#452 Autotools: Resolve use of obsolete macro AC_CONFIG_HEADER
#441 Address compiler warnings
#443 Version info bumped from 7:12:6 to 8:0:7

when used with "-d DIRECTORY"
#356#359 MinGW: Provide declaration of rand_s for mingwrt <5.3.0
#383#392 Autotools: Use -Werror while configure tests the compiler
for supported compile flags to avoid false positives
#383#393#394 Autotools: Improve handling of user (C|CPP|CXX|LD)FLAGS,
e.g. ensure that they have the last word over flags added
while running ./configure
#360 CMake: Create libexpatw.{dll,so} and expatw.pc (with emphasis
on suffix "w") with -DEXPAT_CHAR_TYPE=(ushort|wchar_t)
#360 CMake: Detect and deny unsupported build combinations
involving -DEXPAT_CHAR_TYPE=(ushort|wchar_t)
#360 CMake: Install pre-compiled shipped xmlwf.1 manpage in case
of -DEXPAT_BUILD_DOCS=OFF
#375#380#419 CMake: Fix use of Expat by means of add_subdirectory
#407#408 CMake: Keep expat target name constant at "expat"
(i.e. refrain from using the target name to control
build artifact filenames)
#385 CMake: Fix compilation with -DEXPAT_SHARED_LIBS=OFF for
Windows
CMake: Expose man page compilation as target "xmlwf-manpage"
#413#414 CMake: Introduce option EXPAT_BUILD_PKGCONFIG

Other changes:
examples: Drop executable bits from elements.c
#349 Windows: Change the name of the Windows DLLs from expat*.dll
to libexpat*.dll once more (regression from 2.2.8, first
fixed in 1.95.3, issue #61 on SourceForge today,
was issue #432456 back then); needs a fix due
case-insensitive file systems on Windows and the fact that
Perl's XML::Parser::Expat compiles into Expat.dll.
#347 Windows: Only define _CRT_RAND_S if not defined

The manpages use unadorned libmansuffix instead of __libmansuffix__ or
@libmansuffix@ that the standard transformations handle.
Add ad-hoc s/// command for it. It has "3" hardcoded because there's
no easy way to look up that mapping, but then that very same "3" is
hardcoded in the file names anyway.
XShapeQueryExtension.3 and XShapeQueryVersion.3 are not conjoined twins.
While here split XShape.3 links into separate MLINKS += src dst assignments
and sort them.
