1.1 deraadt 519: <ul>
1.79 deraadt 520: <li>Security:
521: <ul>
522: <li>ssh-agent(1): Will now refuse to load PKCS#11 modules from paths
523: outside a trusted whitelist (run-time configurable). Requests to
524: load modules could be passed via agent forwarding and an attacker
525: could attempt to load a hostile PKCS#11 module across the forwarded
526: agent channel: PKCS#11 modules are shared libraries, so this would
527: result in code execution on the system running the ssh-agent if the
528: attacker has control of the forwarded agent-socket (on the host
529: running the sshd server) and the ability to write to the filesystem
530: of the host running ssh-agent (usually the host running the ssh
531: client).
532: <li>sshd(8): When privilege separation is disabled, forwarded Unix-
533: domain sockets would be created by sshd(8) with the privileges of
534: 'root' instead of the authenticated user. This release refuses
535: Unix-domain socket forwarding when privilege separation is disabled
536: (Privilege separation has been enabled by default for 14 years).
537: <li>sshd(8): Avoid theoretical leak of host private key material to
538: privilege-separated child processes via realloc() when reading
539: keys. No such leak was observed in practice for normal-sized keys,
540: nor does a leak to the child processes directly expose key material
541: to unprivileged users.
542: <li>sshd(8): The shared memory manager used by pre-authentication
543: compression support had a bounds checks that could be elided by
544: some optimising compilers. Additionally, this memory manager was
545: incorrectly accessible when pre-authentication compression was
546: disabled. This could potentially allow attacks against the
547: privileged monitor process from the sandboxed privilege-separation
548: process (a compromise of the latter would be required first).
549: This release removes support for pre-authentication compression
550: from sshd(8).
551: <li>sshd(8): Fix denial-of-service condition where an attacker who
552: sends multiple KEXINIT messages may consume up to 128MB per
553: connection.
554: <li>sshd(8): Validate address ranges for AllowUser and DenyUsers
555: directives at configuration load time and refuse to accept invalid
556: ones. It was previously possible to specify invalid CIDR address
557: ranges (e.g. user@127.1.2.3/55) and these would always match,
558: possibly resulting in granting access where it was not intended.
559: <li>ssh(1), sshd(8): Fix weakness in CBC padding oracle countermeasures
560: that allowed a variant of the attack fixed in OpenSSH 7.3 to proceed.
561: </ul>
562: <li>New/changed features:
563: <ul>
564: <li>Server support for the SSH v.1 protocol has been removed.
565: <li>ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit
566: block ciphers are not safe in 2016 and we don't want to wait until
567: attacks like SWEET32 are extended to SSH. As 3des-cbc was the
568: only mandatory cipher in the SSH RFCs, this may cause problems
569: connecting to older devices using the default configuration,
570: but it's highly likely that such devices already need explicit
571: configuration for key exchange and hostkey algorithms already
572: anyway.
573: <li>sshd(8): Remove support for pre-authentication compression.
574: Doing compression early in the protocol probably seemed reasonable
575: in the 1990s, but today it's clearly a bad idea in terms of both
576: cryptography (cf. multiple compression oracle attacks in TLS) and
577: attack surface. Pre-auth compression support has been disabled by
578: default for >10 years. Support remains in the client.
579: <li>ssh-agent will refuse to load PKCS#11 modules outside a whitelist
580: of trusted paths by default. The path whitelist may be specified
581: at run-time.
582: <li>sshd(8): When a forced-command appears in both a certificate and
583: an authorized keys/principals command= restriction, sshd will now
584: refuse to accept the certificate unless they are identical.
585: The previous (documented) behaviour of having the certificate
586: forced-command override the other could be a bit confusing and
587: error-prone.
588: <li>sshd(8): Remove the UseLogin configuration directive and support
589: for having /bin/login manage login sessions.
590: <li>ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by the
591: version in PuTTY by Simon Tatham. This allows a multiplexing
592: client to communicate with the master process using a subset of
593: the SSH packet and channels protocol over a Unix-domain socket,
594: with the main process acting as a proxy that translates channel
595: IDs, etc. This allows multiplexing mode to run on systems that
596: lack file- descriptor passing (used by current multiplexing
597: code) and potentially, in conjunction with Unix-domain socket
598: forwarding, with the client and multiplexing master process on
599: different machines. Multiplexing proxy mode may be invoked using
600: "ssh -O proxy ..."
601: <li>sshd(8): Add a sshd_config DisableForwarding option that disables
602: X11, agent, TCP, tunnel and Unix domain socket forwarding, as well
603: as anything else we might implement in the future. Like the
604: 'restrict' authorized_keys flag, this is intended to be a simple
605: and future-proof way of restricting an account.
606: <li>sshd(8), ssh(1): Support the "curve25519-sha256" key exchange
607: method. This is identical to the currently-supported method named
608: "curve25519-sha256@libssh.org".
609: <li>sshd(8): Improve handling of SIGHUP by checking to see if sshd is
610: already daemonised at startup and skipping the call to daemon(3)
611: if it is. This ensures that a SIGHUP restart of sshd(8) will
612: retain the same process-ID as the initial execution. sshd(8) will
613: also now unlink the PidFile prior to SIGHUP restart and re-create
614: it after a successful restart, rather than leaving a stale file in
615: the case of a configuration error.
616: <li>sshd(8): Allow ClientAliveInterval and ClientAliveCountMax
617: directives to appear in sshd_config Match blocks.
618: <li>sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to match
619: those supported by AuthorizedKeysCommand (key, key type,
620: fingerprint, etc.) and a few more to provide access to the
621: contents of the certificate being offered.
622: <li>Added regression tests for string matching, address matching and
623: string sanitisation functions.
624: <li>Improved the key exchange fuzzer harness.
625: <li>Deprecate the sshd_config UsePrivilegeSeparation
626: option, thereby making privilege separation mandatory. Privilege
627: separation has been on by default for almost 15 years and
628: sandboxing has been on by default for almost the last five.
629: <li>ssh(1), sshd(8): Support "=-" syntax to easily remove methods from
630: algorithm lists, e.g. Ciphers=-*cbc.
631: </ul>
632: <li>The following significant bugs have been fixed in this release:
633: <ul>
634: <li>ssh(1): Allow IdentityFile to successfully load and use
635: certificates that have no corresponding bare public key.
636: certificate id_rsa-cert.pub (and no id_rsa.pub).
637: <li>ssh(1): Fix public key authentication when multiple
638: authentication is in use and publickey is not just the first
639: method attempted.
640: <li>ssh-agent(1), ssh(1): improve reporting when attempting to load
641: keys from PKCS#11 tokens with fewer useless log messages and more
642: detail in debug messages.
643: <li>ssh(1): When tearing down ControlMaster connections, don't
644: pollute stderr when LogLevel=quiet.
645: <li>sftp(1): On ^Z wait for underlying ssh(1) to suspend before
646: suspending sftp(1) to ensure that ssh(1) restores the terminal mode
647: correctly if suspended during a password prompt.
648: <li>ssh(1): Avoid busy-wait when ssh(1) is suspended during a password
649: prompt.
650: <li>ssh(1), sshd(8): Correctly report errors during sending of ext-
651: info messages.
652: <li>sshd(8): fix NULL-deref crash if sshd(8) received an out-of-
653: sequence NEWKEYS message.
654: <li>sshd(8): Correct list of supported signature algorithms sent in
655: the server-sig-algs extension.
656: <li>sshd(8): Fix sending ext_info message if privsep is disabled.
657: <li>sshd(8): more strictly enforce the expected ordering of privilege
658: separation monitor calls used for authentication and allow them
659: only when their respective authentication methods are enabled
660: in the configuration
661: <li>sshd(8): Fix uninitialised optlen in getsockopt() call; harmless
662: on Unix/BSD but potentially crashy on Cygwin.
663: <li>Fix false positive reports caused by explicit_bzero(3) not being
664: recognised as a memory initialiser when compiled with
665: -fsanitize-memory.
666: <li>sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet for
667: configuration examples.
668: <li>sshd(1): Fix NULL dereference crash when key exchange start
669: messages are sent out of sequence.
670: <li>ssh(1), sshd(8): Allow form-feed characters to appear in
671: configuration files.
672: <li>sshd(8): Fix regression in OpenSSH 7.4 support for the
673: server-sig-algs extension, where SHA2 RSA signature methods were
674: not being correctly advertised.
675: <li>ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in
676: known_hosts processing.
677: <li>ssh(1): Allow ssh to use certificates accompanied by a private key
678: file but no corresponding plain *.pub public key.
679: <li>ssh(1): When updating hostkeys using the UpdateHostKeys option,
680: accept RSA keys if HostkeyAlgorithms contains any RSA keytype.
681: Previously, ssh could ignore RSA keys when only the ssh-rsa-sha2-*
682: methods were enabled in HostkeyAlgorithms and not the old ssh-rsa
683: method.
684: <li>ssh(1): Detect and report excessively long configuration file

690: <li>ssh(1), sshd(8): When logging long messages to stderr, don't truncate
691: "\r\n" if the length of the message exceeds the buffer.
692: <li>ssh(1): Fully quote [host]:port in generated ProxyJump/-J command-
693: line; avoid confusion over IPv6 addresses and shells that treat
694: square bracket characters specially.
695: <li>ssh-keygen(1): Fix corruption of known_hosts when running
696: "ssh-keygen -H" on a known_hosts containing already-hashed entries.
697: <li>Fix various fallout and sharp edges caused by removing SSH protocol
698: 1 support from the server, including the server banner string being
699: incorrectly terminated with only \n (instead of \r\n), confusing
700: error messages from ssh-keyscan a segfault in sshd
701: if protocol v.1 was enabled for the client and sshd_config
702: contained references to legacy keys.
703: <li>ssh(1), sshd(8): Free fd_set on connection timeout.
704: <li>sshd(8): Fix Unix domain socket forwarding for root (regression in
705: OpenSSH 7.4).
706: <li>sftp(1): Fix division by zero crash in "df" output when server
707: returns zero total filesystem blocks/inodes.
708: <li>ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors
709: encountered during key loading to more meaningful error codes.
710: <li>ssh-keygen(1): Sanitise escape sequences in key comments sent to
711: printf but preserve valid UTF-8 when the locale supports it.
712: <li>ssh(1), sshd(8): Return reason for port forwarding failures where
713: feasible rather than always "administratively prohibited".
714: <li>sshd(8): Fix deadlock when AuthorizedKeysCommand or
715: AuthorizedPrincipalsCommand produces a lot of output and a key is
716: matched early.
717: <li>ssh(1): Fix typo in ~C error message for bad port forward
718: cancellation.
719: <li>ssh(1): Show a useful error message when included config files
720: can't be opened.
721: <li>sshd(8): Make sshd set GSSAPIStrictAcceptorCheck=yes as the manual page
722: (previously incorrectly) advertised.
723: <li>sshd_config(5): Repair accidentally-deleted mention of %k token
724: in AuthorizedKeysCommand.
725: <li>sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM;
726: <li>ssh-agent(1): Relax PKCS#11 whitelist to include libexec and
727: common 32-bit compatibility library directories.
728: <li>sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME
729: response handling.
730: <li>ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted
731: keys. It was not possible to delete them except by specifying
732: their full physical path.

736:
1.61 beck 737: <li>LibreSSL 2.5.3
1.80 deraadt 738: <ul>
739: <li>libtls now supports ALPN and SNI
740: <li>libtls adds a new callback interface for integrating custom IO
741: functions. Thanks to Tobias Pape.
742: <li>libtls now handles 4 cipher suite groups:
743: <ul>
744: <li>"secure" (TLSv1.2+AEAD+PFS)
745: <li>"compat" (HIGH:!aNULL)
746: <li>"legacy" (HIGH:MEDIUM:!aNULL)
747: <li>"insecure" (ALL:!aNULL:!eNULL)
748: </ul>
749: This allows for flexibility and finer grained control, rather than
750: having two extremes (an issue raised by Marko Kreen some time ago).
751: <li>Tightened error handling for tls_config_set_ciphers().
752: <li>libtls now always loads CA, key and certificate files at the time the
753: configuration function is called. This simplifies code and results in
754: a single memory based code path being used to provide data to libssl.
1.84 jsing 755: <li>Added support for OCSP intermediate certificates.
756: <li>Added X509_check_host(), X509_check_email(), X509_check_ip(), and
757: X509_check_ip_asc() functions, via BoringSSL.
1.80 deraadt 758: <li>Added initial support for iOS, thanks to Jacob Berkman.
759: <li>Improved behavior of arc4random on Windows when using memory leak
760: analysis software.
761: <li>Correctly handle an EOF that occurs prior to the TLS handshake
762: completing. Reported by Vasily Kolobkov, based on a diff from Marko
763: Kreen.
1.84 jsing 764: <li>Limit the support of the "backward compatible" SSLv2 handshake to
1.80 deraadt 765: only be used if TLS 1.0 is enabled.
766: <li>Fix incorrect results in certain cases on 64-bit systems when
767: BN_mod_word() can return incorrect results. BN_mod_word() now can
768: return an error condition. Thanks to Brian Smith.
1.84 jsing 769: <li>Added constant-time updates to address CVE-2016-0702.
770: <li>Fixed undefined behavior in BN_GF2m_mod_arr().
771: <li>Removed unused Cryptographic Message Support (CMS).
772: <li>More conversions of long long idioms to time_t.
1.80 deraadt 773: <li>Improved compatibility by avoiding printing NULL strings with
774: printf.
775: <li>Reverted change that cleans up the EVP cipher context in
1.84 jsing 776: EVP_EncryptFinal() and EVP_DecryptFinal(). Some software relies on the
777: previous behaviour.
1.80 deraadt 778: <li>Avoid unbounded memory growth in libssl, which can be triggered
779: by a TLS client repeatedly renegotiating and sending OCSP Status
780: Request TLS extensions.
781: <li>Avoid falling back to a weak digest for (EC)DH when using SNI
782: with libssl.
783: <li>X509_cmp_time() now passes a malformed GeneralizedTime field as
784: an error. Reported by Theofilos Petsios.
785: <li>Check for and handle failure of HMAC_{Update,Final} or
786: EVP_DecryptUpdate().
787: <li>Massive update and normalization of manpages, conversion to
788: mandoc format. Many pages were rewritten for clarity and accuracy.
789: Portable doc links are up-to-date with a new conversion tool.
1.82 jsing 790: <li>Curve25519 and TLS X25519 Key Exchange support.
1.80 deraadt 791: <li>Support for alternate chains for certificate verification.
792: <li>Code cleanups, CBB conversions, further unification of DTLS/SSL
793: handshake code, further ASN1 macro expansion and removal.
794: <li>Private symbols are now hidden in libssl and libcrypto.
795: <li>Friendly certificate verification error messages in libtls, peer
796: verification is now always enabled.
797: <li>Added OCSP stapling support to libtls and nc.
798: <li>Added ocspcheck utility to validate a certificate against its OCSP
799: responder and save the reply for stapling
800: <li>Enhanced regression tests and error handling for libtls.
801: <li>Added explicit constant and non-constant time BN functions,
802: defaulting to constant time wherever possible.
803: <li>Moved many leaked implementation details in public structs behind
804: opaque pointers.
805: <li>Added ticket support to libtls.
806: <li>Added support for setting the supported EC curves via
807: SSL{_CTX}_set1_groups{_list}() - also provide defines for the
808: previous SSL{_CTX}_set1_curves{_list} names. This also changes
809: the default list of curves to be X25519, P-256 and P-384. All
810: other curves must be manually enabled.
811: <li>Added -groups option to openssl(1) s_client for specifying the
812: curves to be used in a colon-separated list.
813: <li>Merged client/server version negotiation code paths into one,
814: reducing much duplicate code.
815: <li>Removed error function codes from libssl and libcrypto.
816: <li>Fixed an issue where a truncated packet could crash via an OOB
817: read.
818: <li>Added SSL_OP_NO_CLIENT_RENEGOTIATION option that disallows
819: client-initiated renegotiation. This is the default for libtls
820: servers.
821: <li>Avoid a side-channel cache-timing attack that can leak the ECDSA
822: private keys when signing. This is due to BN_mod_inverse() being
823: used without the constant time flag being set. Reported by Cesar
824: Pereida Garcia and Billy Brumley (Tampere University of
825: Technology). The fix was developed by Cesar Pereida Garcia.
826: <li>iOS and MacOS compatibility updates from Simone Basso and Jacob
827: Berkman.
828: <li>Added the recallocarray(3) memory allocation function, and
829: converted various places in the library to use it, such as CBB
830: and BUF_MEM_grow. recallocarray(3) is similar to
831: reallocarray. Newly allocated memory is cleared similar to
832: calloc(3). Memory that becomes unallocated while shrinking or
833: moving existing allocations is explicitly discarded by unmapping
834: or clearing to 0.
835: <li>Added new root CAs from SECOM Trust Systems / Security
836: Communication of Japan.
837: <li>Added EVP interface for MD5+SHA1 hashes.
838: <li>Improved nc(1) TLS handshake CPU usage and server-side error
839: reporting.
1.84 jsing 840: <li>Added a constant time version of BN_gcd and use it default for
1.80 deraadt 841: BN_gcd to avoid the possibility of sidechannel timing attacks
842: against RSA private key generation - Thanks to Alejandro

1.92 tj 1232: So, in order to keep up to date with the -stable branch, you must make
1.1 deraadt 1233: the <i>ports/</i> tree available on a read-write medium and update the tree
1234: with a command like:
1235:
1236: <blockquote><pre>

1238: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_1</b>

1240:
1241: [Of course, you must replace the server name here with a nearby anoncvs
1242: server.]
1243: <p>
1244: Note that most ports are available as packages on our mirrors. Updated
1245: ports for the 6.1 release will be made available if problems arise.
1246: <p>
1247: If you're interested in seeing a port added, would like to help out, or just
1248: would like to know more, the mailing list
1249: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
