mail/postfix: upadte to 3.8.5

3.8.5 (2024-01-22)

Security: this release improves support to defend against an email
spoofing attack (SMTP smuggling) on recipients at a Postfix server. For
background, see https://www.postfix.org/smtp-smuggling.html.

The improvements provide better logging, and better compatibility with
existing SMTP clients (less need to allowlist clients).

Sites concerned about SMTP smuggling attacks should enable this feature
on Internet-facing Postfix servers. For compatibility with non-standard
clients, Postfix by default excludes clients in mynetworks from this
countermeasure.

The recommended settings are:

    # Require the standard End-of-DATA sequence \ 
<CR><LF>.<CR><LF>.
    # Otherwise, allow bare <LF> and process it as if the client sent
    # <CR><LF>.
    #
    # This maintains compatibility with many legitimate SMTP client
    # applications that send a mix of standard and non-standard line
    # endings, but will fail to receive email from client implementations
    # that do not terminate DATA content with the standard End-of-DATA
    # sequence <CR><LF>.<CR><LF>.
    #
    # Such clients can be allowlisted with smtpd_forbid_bare_newline_exclusions.
    # The example below allowlists SMTP clients in trusted networks.
    #
    smtpd_forbid_bare_newline = normalize
    smtpd_forbid_bare_newline_exclusions = $mynetworks

Notes:

  * The default setting is "smtpd_forbid_bare_newline = no" in Postfix
    releases < 3.9, for compatibility reasons. This means that Postfix
    is by default vulnerable to SMTP smuggling.

  * The new setting "smtpd_forbid_bare_newline = normalize" is the
    default for Postfix releases 3.9 and later.

  * The old setting "smtpd_forbid_bare_newline = yes" is now an alias for
    "smtpd_forbid_bare_newline = normalize".

  * The new setting "smtpd_forbid_bare_newline = reject" will refuse
    commands or message content with a bare newline. For details see
    the RELEASE_NOTES or the postconf(5) documentation.

	Bugfix (bug introduced: 20140218): when opportunistic TLS fails
	during or after the handshake, don't require that a probe
	message spent a minimum time-in-queue before falling back to
	plaintext. Problem reported by Serg. File: smtp/smtp.h.

20230819

	Bugfix (defect introduced: 19980207): the valid_hostname()
	check in the Postfix DNS client library was blocking unusual
	but legitimate wildcard names (*.name) in some DNS lookup
	results and lookup requests. Examples:

            name          class/type value
            *.one.example   IN CNAME *.other.example
            *.other.example IN A     10.0.0.1
            *.other.example IN TLSA  ..certificate info...

	Such syntax is blesed in RFC 1034 section 4.3.3.

	This problem was reported first in the context of TLSA
	record lookups. Files: util/valid_hostname.[hc],
	dns/dns_lookup.c.

20230929

	Bugfix (defect introduced Postfix 2.5, 20080104): the Postfix
	SMTP server was waiting for a client command instead of
	replying immediately, after a client certificate verification
	error in TLS wrappermode. Reported by Andreas Kinzler. File:
	smtpd/smtpd.c.

20231006

	Usability: the Postfix SMTP server now attempts to log the
	SASL username after authentication failure. In Postfix
	logging, this appends ", sasl_username=xxx" after the reason
	for SASL authentication failure. The logging replaces an
	unavailable reason with "(reason unavailable)", and replaces
	an unavailable sasl_username with "(unavailable)". Based
	on code by Jozsef Kadlecsik. Files: xsasl/xsasl_server.c,
	xsasl/xsasl_cyrus_server.c, smtpd/smtpd_sasl_glue.c.

20231026

	Bugfix (defect introduced: Postfix 2.11): in forward_path,
	the expression ${recipient_delimiter} would expand to an
	empty string when a recipient address had no recipient
	delimiter. Fixed by restoring Postfix 2.10 behavior to use
	a configured recipient delimiter value. Reported by Tod
	A. Sandman. Files: proto/postconf.proto, local/local_expand.c.

20231221

	Security: with "smtpd_forbid_bare_newline = yes" (default
	"no" for Postfix < 3.9), reply with "Error: bare <LF>
	received" and disconnect when an SMTP client sends a line
	ending in <LF>, violating the RFC 5321 requirement that
	lines must end in <CR><LF>. This prevents SMTP smuggling
	attacks that target a recipient at a Postfix server. For
	backwards compatibility, local clients are excluded by
	default with "smtpd_forbid_bare_newline_exclusions =
	$mynetworks". Files: mantools/postlink, proto/postconf.proto,
	global/mail_params.h, global/smtp_stream.c, global/smtp_stream.h,
	smtpd/smtpd.c.

postfix: Update to 3.8.1

Major changes with Postfix 3.8.1
================================

- Security: the Postfix SMTP server optionally disconnects remote SMTP clients
  that violate RFC 2920 (or 5321) command pipelining constraints. The server
  replies with "554 5.5.0 Error: SMTP protocol synchronization" and \ 
logs the
  unexpected remote SMTP client input. Specify "smtpd_forbid_unauth_pipelining
  = yes" to enable. This feature is enabled by default in Postfix 3.9 and
  later.

- Workaround to limit collateral damage from OS distributions that crank up
  security to 11, increasing the number of plaintext email deliveries. This
  introduces basic OpenSSL configuration file support, with two new parameters
  "tls_config_file" and "tls_config_name". Details are in \ 
the postconf(5)
  manpage under "tls_config_file" and "tls_config_name".

Log message:
postfix: Update to 3.8.0

upstream changes:
-----------------
Postfix 3.7.8
  o Support to look up DNS SRV records in the Postfix SMTP/LMTP client, Based
    on code by Tomas Korbar (Red Hat). For example, with "use_srv_lookup =
    submission" and "relayhost = example.com:submission", the \ 
Postfix SMTP
    client will look up DNS SRV records for _submission._tcp.example.com, and
    will relay email through the hosts and ports that are specified with those
    records.
  o TLS obsolescence: Postfix now treats the "export" and \ 
"low" cipher grade
    settings as "medium". The "export" and "low" \ 
grades are no longer supported
    in OpenSSL 1.1.1, the minimum version required in Postfix 3.6.0 and later.
    Also, Postfix default settings now exclude deprecated or unused ciphers
    (SEED, IDEA, 3DES, RC2, RC4, RC5), digest (MD5), key exchange algorithms
    (DH, ECDH), and public key algorithm (DSS).
  o Attack resistance: the Postfix SMTP server can now aggregate
    smtpd_client_*_rate and smtpd_client_*_count statistics by network block
    instead of by IP address, to raise the bar against a memory exhaustion
    attack in the anvil(8) server; Postfix TLS support unconditionally disables
    TLS renegotiation in the middle of an SMTP connection, to avoid a CPU
    exhaustion attack.
  o The PostgreSQL client encoding is now configurable with the "encoding"
    Postfix configuration file attribute. The default is "UTF8". \ 
Previously the
    encoding was hard-coded as "LATIN1", which is not useful in the \ 
context of
    SMTP.
  o The postconf command now warns for #comment in or after a Postfix parameter
    value. Postfix programs do not support #comment after other text, and treat
    that as input.

Log message:
mail/postfix: update to 3.7.4

Postfix 3.7.4 (2023-01-22)

  * Workaround: with OpenSSL 3 and later always turn on
    SSL_OP_IGNORE_UNEXPECTED_EOF, to avoid warning messages and missed
    opportunities for TLS session reuse. This is safe because the SMTP
    protocol implements application-level framing, and is therefore not
    affected by TLS truncation attacks. Fix by Viktor Dukhovni.

  * Workaround: OpenSSL 3.x EVP_get_digestbyname() can return
    lazily-bound handles for digest implementations. In sufficiently
    hostile configurations, Postfix could mistakenly believe that a digest
    algorithm is available, and fail when it is not. A similar workaround
    may be needed for EVP_get_cipherbyname(). Fix by Viktor Dukhovni.

  * Bugfix (bug introduced in Postfix 2.11): the checkok() macro in
    tls/tls_fprint.c evaluated its argument unconditionally; it should
    evaluate the argument only if there was no prior error. Found during
    code review.

  * Bugfix (bug introduced in Postfix 2.8): postscreen died with a
    segmentation violation when postscreen_dnsbl_threshold < 1. It
    should reject such input with a fatal error instead. Discovered by
    Benny Pedersen.

  * Bitrot: fixes for linker warnings from newer Darwin (MacOS)
    versions. Viktor Dukhovni.

  * Portability: Linux 6 support.

  * Added missing documentation that cidr:, pcre: and regexp: tables
    support inline specification only in Postfix 3.7 and later.
