1.7 tb 273: <li>Security fixes
274: <ul>
275: <li>Disabled TLSv1.0 and TLSv1.1 in libssl so that they may no longer
276: be selected for use.

278: 32 kbits for primality. This mitigates various DoS vectors.
279: <li>Restricted the RFC 3779 code to IPv4 and IPv6. It was not written
280: to be able to deal with anything else.
281: </ul>
282: <li>Portable changes
283: <ul>
284: <li>Extended the endian.h compat header with hto* and *toh macros.

290: <li>Internal compatibility function symbols are no longer exported from
291: libcrypto. Instead, the libcompat library is linked to libcrypto,
292: libssl, and libtls separately. This increases size a little, but
293: ensures that the libraries are not exporting symbols to programs
294: unintentionally.
295: <li>Selective removal of CET implementation on platforms where it is
296: not supported (macOS).
297: <li>Integrated four more tests.
298: <li>Added Windows ARM64 architecture to tested platforms.

301: <code>--enable-libtls-only</code> is specified at configure time.
302: <li>Improved Windows compatibility library, namely handling of files vs
303: sockets, correcting an exception when operating on a closed socket.
304: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
305: instead using flags from the CMake build type instead.
306: <li>Set the CMake default build type to <code>Release</code>. This can be overridden
307: during configuration.
308: <li>Fixed broken ASM support with MinGW builds.
309: </ul>
1.1 deraadt 310: <li>New features
311: <ul>
1.7 tb 312: <li>Added support for truncated SHA-2 and for SHA-3.

1.7 tb 324: <li>Added a workaround for a poorly thought-out change in OpenSSL 3 that
325: broke privilege separation support in libtls.
326: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
327: <li>Removed GF2m support: BIGNUM no longer supports binary extension
328: field arithmetic and all binary elliptic builtin curves were removed.

338: <li>Removed SXNET and NETSCAPE_CERT_SEQUENCE support including the
1.8 tb 339: openssl(1) nseq command.
1.7 tb 340: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
341: of this, some stub functions are provided to avoid patching some
342: applications that do not honor OPENSSL_NO_ENGINE.
343: <li>The POLICY_TREE and its related structures and API were removed.
344: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
345: host list.
346: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
347: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
348: each other.
349: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
350: valid UTF-8 without embedded NUL.
351: <li>The explicitText user notice uses UTF8String instead of VisibleString
352: to reduce the risk of emitting certificates with invalid DER-encoding.
353: <li>Initial fixes for RSA-PSS support to make the TLSv1.3 stack more
354: compliant with RFC 8446.
355: <li>Fixed EVP_CIPHER_CTX_iv_length() to return what was set with

1.12 dtucker 438: <li>Potentially incompatible changes
1.1 deraadt 439: <ul>
1.12 dtucker 440: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
441: generate Ed25519 keys by default. Ed25519 public keys
442: are very convenient due to their small size. Ed25519 keys are
443: specified in RFC 8709 and OpenSSH has supported them since version 6.5
444: (January 2014).
445: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
446: the Subsystem directive now accurately preserves quoting of
447: subsystem commands and arguments. This may change behaviour for exotic
448: configurations, but the most common subsystem configuration
449: (sftp-server) is unlikely to be affected.
1.13 dtucker 450: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
451: PKCS#11 modules must now be specified by their full
452: paths. Previously dlopen(3) could search for them in system
453: library directories.
1.1 deraadt 454: </ul>
1.12 dtucker 455: <li>New features
1.1 deraadt 456: <ul>
1.12 dtucker 457: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
458: add keystroke timing obfuscation to the client. This attempts
459: to hide inter-keystroke timings by sending interactive traffic at
460: fixed intervals (default: every 20ms) when there is only a small
461: amount of data being sent. It also sends fake "chaff" keystrokes for
462: a random interval after the last real keystroke. These are
463: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
464: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
465: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
466: Introduce a transport-level ping facility. This adds
467: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
468: implement a ping capability. These messages use numbers in the "local
469: extensions" number space and are advertised using a "ping@openssh.com"
470: ext-info message with a string version number of "0".
1.13 dtucker 471: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
472: allow override of Subsystem directives in sshd Match blocks.
473: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
474: allow forwarding Unix Domain sockets via ssh -W.
475: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
476: add support for configuration tags to ssh(1).
477: This adds a ssh_config(5) "Tag" directive and corresponding
478: "Match tag" predicate that may be used to select blocks of
479: configuration similar to the pf.conf(5) keywords of the same
480: name.
481: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
482: add a "match localnetwork" predicate. This allows matching
483: on the addresses of available network interfaces and may be used to
484: vary the effective client configuration based on network location.
485: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
486: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
487: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
488: infrastructure support for KRL
489: extensions. This defines wire formats for optional KRL extensions
490: and implements parsing of the new submessages. No actual extensions
491: are supported at this point.
492: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
493: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
494: accept two additional %-expansion sequences: %D which expands to
495: the routing domain of the connected session and %C which expands
496: to the addresses and port numbers for the source and destination
497: of the connection.
498: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
499: increase the default work factor (rounds) for the
500: bcrypt KDF used to derive symmetric encryption keys for passphrase
501: protected key files by 50%.
1.1 deraadt 502: </ul>
503: <li>Bugfixes
504: <ul>
1.12 dtucker 505: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
506: fix scp in SFTP mode recursive upload and download of
507: directories that contain symlinks to other directories. In scp mode,
508: the links would be followed, but in SFTP mode they were not.
509: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
510: handle cr+lf (instead of just cr) line endings in
511: sshsig signature files.
512: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
513: interactive mode for ControlPersist sessions if they
514: originally requested a tty.
515: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
516: make PerSourceMaxStartups first-match-wins
517: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
518: limit artificial login delay to a reasonable maximum (5s)
519: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 520: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
521: Log errors in kex_exchange_identification() with level
1.12 dtucker 522: verbose instead of error to reduce preauth log spam. All of those
523: get logged with a more generic error message by sshpkt_fatal().
524: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
525: correct math for ClientAliveInterval that caused the probes
526: to be sent less frequently than configured.
1.13 dtucker 527: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
528: improve isolation between loaded PKCS#11 modules
529: by running separate ssh-pkcs11-helpers for each loaded provider.
530: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
531: make -f (fork after authentication) work correctly with
532: multiplexed connections, including ControlPersist.
533: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
534: make ConnectTimeout apply to multiplexing sockets and not
535: just to network connections.
536: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
537: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
538: improve defences against invalid PKCS#11
539: modules being loaded by checking that the requested module
540: contains the required symbol before loading it.
541: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
542: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
543: appears before it in sshd_config. Since OpenSSH 8.7 the
544: AuthorizedPrincipalsCommand directive was incorrectly ignored in
545: this situation.
546: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
547: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
548: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
549: remove vestigal support for KRL
550: signatures When the KRL format was originally defined, it included
551: support for signing of KRL objects. However, the code to sign KRLs
552: and verify KRL signatues was never completed in OpenSSH. This
553: release removes the partially-implemented code to verify KRLs.
554: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
555: KRL files.
556: <li>All: fix a number of memory leaks and unreachable/harmless integer
557: overflows.
558: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
559: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
560: don't truncate strings logged from PKCS#11 modules
561: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
562: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
563: better validate CASignatureAlgorithms in
564: ssh_config and sshd_config. Previously this directive would accept
565: certificate algorithm names, but these were unusable in practice as
566: OpenSSH does not support CA chains.
567: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
568: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
569: algorithms that are valid for CA signing. Previous behaviour was
570: to list all signing algorithms, including certificate algorithms.
571: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
572: gracefully handle systems where rlimits or the
573: maximum number of open files is larger than INT_MAX
574: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
575: fix "no comment" not showing on when running
576: <code>ssh-keygen -l</code> on multiple keys where one has a comment
577: and other following keys do not.
578: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 579: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 580: adjust ftruncate() logic to handle servers that
581: reorder requests. Previously, if the server reordered requests then
582: the resultant file would be erroneously truncated.
583: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
584: don't incorrectly disable hostname canonicalization when
585: CanonicalizeHostname=yes and ProxyJump was expicitly set to
586: "none".
587: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:

1.3 jsg 879: If you already have an OpenBSD 7.3 system, and do not want to reinstall,
1.1 deraadt 880: upgrade instructions and advice can be found in the

887: <h3>Notes about the source code</h3>
888: <p>
889: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
890: This file contains everything you need except for the kernel sources,
891: which are in a separate archive.
892: To extract:
893: <blockquote><pre>
894: # <kbd>mkdir -p /usr/src</kbd>
895: # <kbd>cd /usr/src</kbd>
896: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
897: </pre></blockquote>
898: <p>
899: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
900: This file contains all the kernel sources you need to rebuild kernels.
901: To extract:
902: <blockquote><pre>
903: # <kbd>mkdir -p /usr/src/sys</kbd>
904: # <kbd>cd /usr/src</kbd>
905: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
906: </pre></blockquote>
907: <p>
908: Both of these trees are a regular CVS checkout. Using these trees it
909: is possible to get a head-start on using the anoncvs servers as
910: described <a href="anoncvs.html">here</a>.
911: Using these files
912: results in a much faster initial CVS update than you could expect from
913: a fresh checkout of the full OpenBSD source tree.

919: <h3>Ports Tree</h3>
920: <p>
921: A ports tree archive is also provided. To extract:
922: <blockquote><pre>
923: # <kbd>cd /usr</kbd>
924: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
925: </pre></blockquote>
926: <p>
927: Go read the <a href="faq/ports/index.html">ports</a> page
928: if you know nothing about ports
929: at this point. This text is not a manual of how to use ports.
930: Rather, it is a set of notes meant to kickstart the user on the
931: OpenBSD ports system.
932: <p>
933: The <i>ports/</i> directory represents a CVS checkout of our ports.
934: As with our complete source tree, our ports tree is available via
935: <a href="anoncvs.html">AnonCVS</a>.
936: So, in order to keep up to date with the -stable branch, you must make
937: the <i>ports/</i> tree available on a read-write medium and update the tree
938: with a command like:
939: <blockquote><pre>
940: # <kbd>cd /usr/ports</kbd>
1.2 jsg 941: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 942: </pre></blockquote>
943: <p>
944: [Of course, you must replace the server name here with a nearby anoncvs
945: server.]
946: <p>
947: Note that most ports are available as packages on our mirrors. Updated
948: ports for the 7.4 release will be made available if problems arise.
949: <p>
950: If you're interested in seeing a port added, would like to help out, or just
951: would like to know more, the mailing list
952: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
