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

678: known_hosts processing.
679: <li>ssh(1): Allow ssh to use certificates accompanied by a private key
680: file but no corresponding plain *.pub public key.
681: <li>ssh(1): When updating hostkeys using the UpdateHostKeys option,
682: accept RSA keys if HostkeyAlgorithms contains any RSA keytype.
683: Previously, ssh could ignore RSA keys when only the ssh-rsa-sha2-*
684: methods were enabled in HostkeyAlgorithms and not the old ssh-rsa
685: method.
686: <li>ssh(1): Detect and report excessively long configuration file
687: lines.

692: <li>ssh(1), sshd(8): When logging long messages to stderr, don't truncate
693: "\r\n" if the length of the message exceeds the buffer.
694: <li>ssh(1): Fully quote [host]:port in generated ProxyJump/-J command-
695: line; avoid confusion over IPv6 addresses and shells that treat
696: square bracket characters specially.
697: <li>ssh-keygen(1): Fix corruption of known_hosts when running
698: "ssh-keygen -H" on a known_hosts containing already-hashed entries.
699: <li>Fix various fallout and sharp edges caused by removing SSH protocol
700: 1 support from the server, including the server banner string being
701: incorrectly terminated with only \n (instead of \r\n), confusing
702: error messages from ssh-keyscan a segfault in sshd
703: if protocol v.1 was enabled for the client and sshd_config
704: contained references to legacy keys.
705: <li>ssh(1), sshd(8): Free fd_set on connection timeout.
706: <li>sshd(8): Fix Unix domain socket forwarding for root (regression in
707: OpenSSH 7.4).
708: <li>sftp(1): Fix division by zero crash in "df" output when server
709: returns zero total filesystem blocks/inodes.
710: <li>ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors
711: encountered during key loading to more meaningful error codes.

713: printf but preserve valid UTF-8 when the locale supports it.
714: <li>ssh(1), sshd(8): Return reason for port forwarding failures where
715: feasible rather than always "administratively prohibited".

718: matched early.
719: <li>ssh(1): Fix typo in ~C error message for bad port forward
720: cancellation.
721: <li>ssh(1): Show a useful error message when included config files
722: can't be opened.

724: (previously incorrectly) advertised.
725: <li>sshd_config(5): Repair accidentally-deleted mention of %k token
726: in AuthorizedKeysCommand.
727: <li>sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM;
728: <li>ssh-agent(1): Relax PKCS#11 whitelist to include libexec and
729: common 32-bit compatibility library directories.
730: <li>sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME
731: response handling.
732: <li>ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted
733: keys. It was not possible to delete them except by specifying
734: their full physical path.

737: <p>
738:
1.61 beck 739: <li>LibreSSL 2.5.3
1.80 deraadt 740: <ul>
741: <li>libtls now supports ALPN and SNI
742: <li>libtls adds a new callback interface for integrating custom IO
743: functions. Thanks to Tobias Pape.
744: <li>libtls now handles 4 cipher suite groups:
745: <ul>
746: <li>"secure" (TLSv1.2+AEAD+PFS)
747: <li>"compat" (HIGH:!aNULL)
748: <li>"legacy" (HIGH:MEDIUM:!aNULL)
749: <li>"insecure" (ALL:!aNULL:!eNULL)
750: </ul>
751: This allows for flexibility and finer grained control, rather than
752: having two extremes (an issue raised by Marko Kreen some time ago).
753: <li>Tightened error handling for tls_config_set_ciphers().
754: <li>libtls now always loads CA, key and certificate files at the time the
755: configuration function is called. This simplifies code and results in
756: a single memory based code path being used to provide data to libssl.
1.84 jsing 757: <li>Added support for OCSP intermediate certificates.
758: <li>Added X509_check_host(), X509_check_email(), X509_check_ip(), and
759: X509_check_ip_asc() functions, via BoringSSL.
1.80 deraadt 760: <li>Added initial support for iOS, thanks to Jacob Berkman.
761: <li>Improved behavior of arc4random on Windows when using memory leak
762: analysis software.
763: <li>Correctly handle an EOF that occurs prior to the TLS handshake
764: completing. Reported by Vasily Kolobkov, based on a diff from Marko
765: Kreen.
1.84 jsing 766: <li>Limit the support of the "backward compatible" SSLv2 handshake to
1.80 deraadt 767: only be used if TLS 1.0 is enabled.
768: <li>Fix incorrect results in certain cases on 64-bit systems when
769: BN_mod_word() can return incorrect results. BN_mod_word() now can
770: return an error condition. Thanks to Brian Smith.
1.84 jsing 771: <li>Added constant-time updates to address CVE-2016-0702.
772: <li>Fixed undefined behavior in BN_GF2m_mod_arr().
773: <li>Removed unused Cryptographic Message Support (CMS).
774: <li>More conversions of long long idioms to time_t.
1.80 deraadt 775: <li>Improved compatibility by avoiding printing NULL strings with
776: printf.
777: <li>Reverted change that cleans up the EVP cipher context in
1.84 jsing 778: EVP_EncryptFinal() and EVP_DecryptFinal(). Some software relies on the
779: previous behaviour.
1.80 deraadt 780: <li>Avoid unbounded memory growth in libssl, which can be triggered
781: by a TLS client repeatedly renegotiating and sending OCSP Status
782: Request TLS extensions.
783: <li>Avoid falling back to a weak digest for (EC)DH when using SNI
784: with libssl.
785: <li>X509_cmp_time() now passes a malformed GeneralizedTime field as
786: an error. Reported by Theofilos Petsios.
787: <li>Check for and handle failure of HMAC_{Update,Final} or
788: EVP_DecryptUpdate().
789: <li>Massive update and normalization of manpages, conversion to
790: mandoc format. Many pages were rewritten for clarity and accuracy.
791: Portable doc links are up-to-date with a new conversion tool.
1.82 jsing 792: <li>Curve25519 and TLS X25519 Key Exchange support.
1.80 deraadt 793: <li>Support for alternate chains for certificate verification.
794: <li>Code cleanups, CBB conversions, further unification of DTLS/SSL
795: handshake code, further ASN1 macro expansion and removal.
796: <li>Private symbols are now hidden in libssl and libcrypto.
797: <li>Friendly certificate verification error messages in libtls, peer
798: verification is now always enabled.
799: <li>Added OCSP stapling support to libtls and nc.
800: <li>Added ocspcheck utility to validate a certificate against its OCSP
801: responder and save the reply for stapling
802: <li>Enhanced regression tests and error handling for libtls.
803: <li>Added explicit constant and non-constant time BN functions,
804: defaulting to constant time wherever possible.
805: <li>Moved many leaked implementation details in public structs behind
806: opaque pointers.
807: <li>Added ticket support to libtls.
808: <li>Added support for setting the supported EC curves via
809: SSL{_CTX}_set1_groups{_list}() - also provide defines for the
810: previous SSL{_CTX}_set1_curves{_list} names. This also changes
811: the default list of curves to be X25519, P-256 and P-384. All
812: other curves must be manually enabled.
813: <li>Added -groups option to openssl(1) s_client for specifying the
814: curves to be used in a colon-separated list.
815: <li>Merged client/server version negotiation code paths into one,
816: reducing much duplicate code.
817: <li>Removed error function codes from libssl and libcrypto.
818: <li>Fixed an issue where a truncated packet could crash via an OOB
819: read.
820: <li>Added SSL_OP_NO_CLIENT_RENEGOTIATION option that disallows
821: client-initiated renegotiation. This is the default for libtls
822: servers.
823: <li>Avoid a side-channel cache-timing attack that can leak the ECDSA
824: private keys when signing. This is due to BN_mod_inverse() being
825: used without the constant time flag being set. Reported by Cesar
826: Pereida Garcia and Billy Brumley (Tampere University of
827: Technology). The fix was developed by Cesar Pereida Garcia.
828: <li>iOS and MacOS compatibility updates from Simone Basso and Jacob
829: Berkman.
830: <li>Added the recallocarray(3) memory allocation function, and
831: converted various places in the library to use it, such as CBB
832: and BUF_MEM_grow. recallocarray(3) is similar to
833: reallocarray. Newly allocated memory is cleared similar to
834: calloc(3). Memory that becomes unallocated while shrinking or
835: moving existing allocations is explicitly discarded by unmapping
836: or clearing to 0.
837: <li>Added new root CAs from SECOM Trust Systems / Security
838: Communication of Japan.
839: <li>Added EVP interface for MD5+SHA1 hashes.
840: <li>Improved nc(1) TLS handshake CPU usage and server-side error
841: reporting.
1.84 jsing 842: <li>Added a constant time version of BN_gcd and use it default for
1.80 deraadt 843: BN_gcd to avoid the possibility of sidechannel timing attacks
844: against RSA private key generation - Thanks to Alejandro

1197: The <i>ports/</i> directory represents a CVS checkout of our ports.
1198: As with our complete source tree, our ports tree is available via
1199: <a href="anoncvs.html">AnonCVS</a>.
1.92 tj 1200: So, in order to keep up to date with the -stable branch, you must make
1.1 deraadt 1201: the <i>ports/</i> tree available on a read-write medium and update the tree
1202: with a command like:
1203:
1204: <blockquote><pre>
1205: # <b>cd /usr/ports</b>
1206: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_1</b>
1207: </pre></blockquote>
1208:
1209: [Of course, you must replace the server name here with a nearby anoncvs
1210: server.]
1211: <p>
1212: Note that most ports are available as packages on our mirrors. Updated
1213: ports for the 6.1 release will be made available if problems arise.
1214: <p>
1215: If you're interested in seeing a port added, would like to help out, or just
1216: would like to know more, the mailing list
1217: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
