   An update that fixes 30 vulnerabilities is now available.

Description:

   This update for exim fixes the following issues:

   exim was updated to 4.94.2:

   security update (boo#1185631)

     * CVE-2020-28007: Link attack in Exim's log directory
     * CVE-2020-28008: Assorted attacks in Exim's spool directory
     * CVE-2020-28014: Arbitrary PID file creation
     * CVE-2020-28011: Heap buffer overflow in queue_run()
     * CVE-2020-28010: Heap out-of-bounds write in main()
     * CVE-2020-28013: Heap buffer overflow in parse_fix_phrase()
     * CVE-2020-28016: Heap out-of-bounds write in parse_fix_phrase()
     * CVE-2020-28015: New-line injection into spool header file (local)
     * CVE-2020-28012: Missing close-on-exec flag for privileged pipe
     * CVE-2020-28009: Integer overflow in get_stdinput()
     * CVE-2020-28017: Integer overflow in receive_add_recipient()
     * CVE-2020-28020: Integer overflow in receive_msg()
     * CVE-2020-28023: Out-of-bounds read in smtp_setup_msg()
     * CVE-2020-28021: New-line injection into spool header file (remote)
     * CVE-2020-28022: Heap out-of-bounds read and write in extract_option()
     * CVE-2020-28026: Line truncation and injection in spool_read_header()
     * CVE-2020-28019: Failure to reset function pointer after BDAT error
     * CVE-2020-28024: Heap buffer underflow in smtp_ungetc()
     * CVE-2020-28018: Use-after-free in tls-openssl.c
     * CVE-2020-28025: Heap out-of-bounds read in pdkim_finish_bodyhash()

   update to exim-4.94.1

     * 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.
     * Fix security issue in SMTP verb option parsing (CVE-2020-EXOPT)
     * 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.
     * Fix CVE-2020-28016 (PFPZA): Heap out-of-bounds write in
       parse_fix_phrase()
     * Fix security issue CVE-2020-PFPSN and guard against cmdline invoker
       providing a particularly obnoxious sender full name.
     * Fix Linux security issue CVE-2020-SLCWD and guard against PATH_MAX
       better.

   - bring back missing exim_db.8 manual page (fixes boo#1173693)

   - bring in changes from current +fixes (lots of taint check fixes)
     * Bug 1329: Fix format of Maildir-format filenames to match other mail-
       related applications.  Previously an "H" was used where available info
       says that "M" should be, so change to match.
     * 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.
     * 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.
     * 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.

   update to exim 4.94

     * some transports now refuse to use tainted data in constructing their
       delivery location this WILL BREAK configurations which are not updated
       accordingly. In particular: any Transport use of $local_user which has
       been relying upon check_local_user far away in the Router to make it
       safe, should be updated to replace $local_user with $local_part_data.
     * Attempting to remove, in router or transport, a header name that ends
       with an asterisk (which is a standards-legal name) will now result in
       all headers named starting with the string before the asterisk being
       removed.

   - switch pretrans to use lua (fixes boo#1171877)


   - bring changes from current in +fixes branch
     (patch-exim-fixes-ee83de04d3087efaf808d1f2235a988275c2ee94)
     * fixes CVE-2020-12783 (boo#1171490)
     * Regard command-line recipients as tainted.
     * Bug 2489: Fix crash in the "pam" expansion condition.
     * Use tainted buffers for the transport smtp context.
     * Bug 2493: Harden ARC verify against Outlook, which has been seen to
       mix the ordering of its ARC headers.  This caused a crash.
     * 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.
     * Bug 2494: Unset the default for dmarc_tld_file.
     * Fix an uninitialised flag in early-pipelining.  Previously connections
       could, depending on the platform, hang at the STARTTLS response.
     * 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.
     * Bug 2500: Rewind some of the common-coding in string handling between
       the Exim main code and Exim-related utities.
     * Fix the variables set by the gsasl authenticator.
     * Bug 2507: Modules: on handling a dynamic-module (lookups) open failure,
       only retrieve the errormessage once.
     * 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.

   - don't create logfiles during install
     * fixes CVE-2020-8015 (boo#1154183)

   - add a spec-file workaround for boo#1160726

   - update to exim 4.93.0.4 (+fixes release)
     * 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.
     * Early-pipelining support code is now included unless disabled in
       Makefile.
     * 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.
     * 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.
     * Regard command-line receipients as tainted.
     * Bug 340: Remove the daemon pid file on exit, whe due to SIGTERM.
     * 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.
     * 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.
     * Bug 2493: Harden ARC verify against Outlook, whick has been seen to
       mix the ordering of its ARC headers.  This caused a crash.
     * 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.
     * 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.
     * Fix an uninitialised flag in early-pipelining.  Previously connections
       could, depending on the platform, hang at the STARTTLS response.
     * 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.
     * 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.
     * 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.
     * 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.
     * 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.
     * Authentication: the gsasl driver not provides the $authN variables in
       time for the expansion of the server_scram_iter and server_scram_salt
       options.

   spec file cleanup to make update work
   - add docdir to spec

   - update to exim 4.93
     * SUPPORT_DMARC replaces EXPERIMENTAL_DMARC
     * DISABLE_TLS replaces SUPPORT_TLS
     * Bump the version for the local_scan API.
     * smtp transport option hosts_try_fastopen defaults to "*".
     * DNSSec is requested (not required) for all queries. (This seemes to
       ask for trouble if your resolver is a systemd-resolved.)
     * Generic router option retry_use_local_part defaults to "true" under
       specific pre-conditions.
     * Introduce a tainting mechanism for values read from untrusted sources.
     * Use longer file names for temporary spool files (this avoids name
       conflicts with spool on a shared file system).
     * Use dsn_from main config option (was ignored previously).

   - update to exim 4.92.3
     * CVE-2019-16928: fix against Heap-based buffer overflow in
       string_vformat, remote code execution seems to be possible

     * CVE-2019-15846: fix against remote attackers executing arbitrary code
       as root via a trailing backslash

   - update to exim 4.92.1
    * CVE-2019-13917: Fixed an issue with ${sort} expansion which could allow
      remote attackers to execute other programs with root privileges
      (boo#1142207)

   - spec file cleanup
    * fix DANE inclusion guard condition
    * re-enable i18n and remove misleading comment

    * "pipelining" log_selector
    * JSON variants for ${extract } expansion
    * "noutf8" debug option
    * TCP Fast Open support on MacOS
    * CVE-2019-10149: Fixed a Remote Command Execution (boo#1136587)
   - add workaround patch for compile time error on missing printf format
     annotation (gnu_printf.patch)

   - update to 4.91
    * DEFER rather than ERROR on redis cluster MOVED response.
    * Catch and remove uninitialized value warning in exiqsumm
    * Disallow '/' characters in queue names specified for the "queue=" ACL
      modifier.  This matches the restriction on the commandline.
    * Fix pgsql lookup for multiple result-tuples with a single column.
      Previously only the last row was returned.
    * Bug 2217: Tighten up the parsing of DKIM signature headers.
    * Bug 2215: Fix crash associated with dnsdb lookup done from DKIM ACL.
    * Fix issue with continued-connections when the DNS shifts unreliably.
    * Bug 2214: Fix SMTP responses resulting from non-accept result of MIME
      ACL.
    * The "support for" informational output now, which built with Content
      Scanning support, has a line for the malware scanner interfaces
      compiled in.  Interface can be individually included or not at build
      time.
    * The "aveserver", "kavdaemon" and "mksd" interfaces are now not included
      by the template makefile "src/EDITME".  The "STREAM" support for an
      older ClamAV interface method is removed.
    * Bug 2223: Fix mysql lookup returns for the no-data case (when the
      number of rows affected is given instead).
    * The runtime Berkeley DB library version is now additionally output by
      "exim -d -bV".  Previously only the compile-time version was shown.
    * Bug 2230: Fix cutthrough routing for nonfirst messages in an initiating
      SMTP connection.
    * Bug 2229: Fix cutthrough routing for nonstandard port numbers defined
      by routers.
    * Bug 2174: A timeout on connect for a callout was also erroneously seen
      as a timeout on read on a GnuTLS initiating connection, resulting in
      the initiating connection being dropped.
    * Relax results from ACL control request to enable cutthrough, in
      unsupported situations, from error to silently (except under debug)
      ignoring.
    * Fix Buffer overflow in base64d() (CVE-2018-6789)
    * Fix bug in DKIM verify: a buffer overflow could corrupt the malloc
      metadata, resulting in a crash in free().
    * Fix broken Heimdal GSSAPI authenticator integration.
    * Bug 2113: Fix conversation closedown with the Avast malware scanner.
    * Bug 2239: Enforce non-usability of control=utf8_downconvert in the mail
      ACL.
    * Speed up macro lookups during configuration file read, by skipping non-
      macro text after a replacement (previously it was only once per line)
      and by skipping builtin macros when searching for an uppercase lead
      character.
    * DANE support moved from Experimental to mainline.  The Makefile control
      for the build is renamed.
    * Fix memory leak during multi-message connections using STARTTLS.
    * Bug 2236: When a DKIM verification result is overridden by ACL, DMARC
      reported the original.  Fix to report (as far as possible) the ACL
      result replacing the original.
    * Fix memory leak during multi-message connections using STARTTLS under
      OpenSSL
    * Bug 2242: Fix exim_dbmbuild to permit directoryless filenames.
    * Fix utf8_downconvert propagation through a redirect router.
    * Bug 2253: For logging delivery lines under PRDR, append the overall
      DATA response info to the (existing) per-recipient response info for
      the "C=" log element.
    * Bug 2251: Fix ldap lookups that return a single attribute having zero-
      length value.
    * Support Avast multiline protocol, this allows passing flags to newer
      versions of the scanner.
    *  Ensure that variables possibly set during message acceptance are
       marked dead before release of memory in the daemon loop.
    * Bug 2250: Fix a longstanding bug in heavily-pipelined SMTP input (such
      as a multi-recipient message from a mailinglist manager).
    * The (EXPERIMENTAL_DMARC) variable $dmarc_ar_header is withdrawn, being
      replaced by the ${authresults } expansion.
    * Bug 2257: Fix pipe transport to not use a socket-only syscall.
    * Set a handler for SIGTERM and call exit(3) if running as PID 1. This
      allows proper process termination in container environments.
    * Bug 2258: Fix spool_wireformat in combination with LMTP transport.
      Previously the "final dot" had a newline after it; ensure it is CR,LF.
    * SPF: remove support for the "spf" ACL condition outcome values
      "err_temp" and "err_perm", deprecated since 4.83 when the RFC-defined
      words " temperror" and "permerror" were introduced.
    * Re-introduce enforcement of no cutthrough delivery on transports having
      transport-filters or DKIM-signing.
    * Cutthrough: for a final-dot response timeout (and nonunderstood
      responses) in defer=pass mode supply a 450 to the initiator.
      Previously the message would be spooled.
    * DANE: add dane_require_tls_ciphers SMTP Transport option; if unset,
      tls_require_ciphers is used as before.
    * Malware Avast: Better match the Avast multiline protocol.
    * Fix reinitialisation of DKIM logging variable between messages.
    * Bug 2255: Revert the disable of the OpenSSL session caching.
    * Add util/renew-opendmarc-tlds.sh script for safe renewal of public
      suffix list.
    * DKIM: accept Ed25519 pubkeys in SubjectPublicKeyInfo-wrapped form,
      since the IETF WG has not yet settled on that versus the original
      "bare" representation.
    * Fix syslog logging for syslog_timestamp=no and log_selector +millisec.
      Previously the millisecond value corrupted the output. Fix also for
      syslog_pid=no and log_selector +pid, for which the pid corrupted the
      output.

   - Replace xorg-x11-devel by individual pkgconfig() buildrequires.

   - update to 4.90.1
     * Allow PKG_CONFIG_PATH to be set in Local/Makefile and use it correctly
       during configuration.  Wildcards are allowed and expanded.
     * Shorten the log line for daemon startup by collapsing adjacent sets of
       identical IP addresses on different listening ports.  Will also affect
       "exiwhat" output.
     * Tighten up the checking in isip4 (et al): dotted-quad components
       larger than 255 are no longer allowed.
     * Default openssl_options to include +no_ticket, to reduce load on
       peers. Disable the session-cache too, which might reduce our load.
       Since we currrectly use a new context for every connection, both as
       server and client, there is no benefit for these.
     * Add $SOURCE_DATE_EPOCH support for reproducible builds, per spec at
       .
     * Fix smtp transport use of limited max_rcpt under mua_wrapper.
       Previously the check for any unsuccessful recipients did not notice
       the limit, and erroneously found still-pending ones.
     * Pipeline CHUNKING command and data together, on kernels that support
       MSG_MORE.  Only in-clear (not on TLS connections).
     * Avoid using a temporary file during transport using dkim.  Unless a
       transport-filter is involved we can buffer the headers in memory for
       creating the signature, and read the spool data file once for the
       signature and again for transmission.
     * Enable use of sendfile in Linux builds as default.  It was disabled in
       4.77 as the kernel support then wasn't solid, having issues in 64bit
       mode.  Now, it's been long enough.  Add support for FreeBSD also.
     * Add commandline_checks_require_admin option.
     * Do pipelining under TLS.
     * For the "sock" variant of the malware scanner interface, accept an
       empty cmdline element to get the documented default one.  Previously
       it was inaccessible.
     * Prevent repeated use of -p/-oMr
     * DKIM: enforce the DNS pubkey record "h" permitted-hashes optional
       field, if present.
     * DKIM: when a message has multiple signatures matching an identity
       given in dkim_verify_signers, run the dkim acl once for each.
     * Support IDNA2008.
     * The path option on a pipe transport is now expanded before use
     * Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
