1.1 deraadt 518: <ul>
1.79 deraadt 519: <li>Security:
520: <ul>
521: <li>ssh-agent(1): Will now refuse to load PKCS#11 modules from paths
522: outside a trusted whitelist (run-time configurable). Requests to
523: load modules could be passed via agent forwarding and an attacker
524: could attempt to load a hostile PKCS#11 module across the forwarded
525: agent channel: PKCS#11 modules are shared libraries, so this would
526: result in code execution on the system running the ssh-agent if the
527: attacker has control of the forwarded agent-socket (on the host
528: running the sshd server) and the ability to write to the filesystem
529: of the host running ssh-agent (usually the host running the ssh
530: client).
531: <li>sshd(8): When privilege separation is disabled, forwarded Unix-
532: domain sockets would be created by sshd(8) with the privileges of
533: 'root' instead of the authenticated user. This release refuses
534: Unix-domain socket forwarding when privilege separation is disabled
535: (Privilege separation has been enabled by default for 14 years).
536: <li>sshd(8): Avoid theoretical leak of host private key material to
537: privilege-separated child processes via realloc() when reading
538: keys. No such leak was observed in practice for normal-sized keys,
539: nor does a leak to the child processes directly expose key material
540: to unprivileged users.
541: <li>sshd(8): The shared memory manager used by pre-authentication
542: compression support had a bounds checks that could be elided by
543: some optimising compilers. Additionally, this memory manager was
544: incorrectly accessible when pre-authentication compression was
545: disabled. This could potentially allow attacks against the
546: privileged monitor process from the sandboxed privilege-separation
547: process (a compromise of the latter would be required first).
548: This release removes support for pre-authentication compression
549: from sshd(8).
550: <li>sshd(8): Fix denial-of-service condition where an attacker who
551: sends multiple KEXINIT messages may consume up to 128MB per
552: connection.
553: <li>sshd(8): Validate address ranges for AllowUser and DenyUsers
554: directives at configuration load time and refuse to accept invalid
555: ones. It was previously possible to specify invalid CIDR address
556: ranges (e.g. user@127.1.2.3/55) and these would always match,
557: possibly resulting in granting access where it was not intended.
558: <li>ssh(1), sshd(8): Fix weakness in CBC padding oracle countermeasures
559: that allowed a variant of the attack fixed in OpenSSH 7.3 to proceed.
560: </ul>
561: <li>New/changed features:
562: <ul>
563: <li>Server support for the SSH v.1 protocol has been removed.
564: <li>ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit
565: block ciphers are not safe in 2016 and we don't want to wait until
566: attacks like SWEET32 are extended to SSH. As 3des-cbc was the
567: only mandatory cipher in the SSH RFCs, this may cause problems
568: connecting to older devices using the default configuration,
569: but it's highly likely that such devices already need explicit
570: configuration for key exchange and hostkey algorithms already
571: anyway.
572: <li>sshd(8): Remove support for pre-authentication compression.
573: Doing compression early in the protocol probably seemed reasonable
574: in the 1990s, but today it's clearly a bad idea in terms of both
575: cryptography (cf. multiple compression oracle attacks in TLS) and
576: attack surface. Pre-auth compression support has been disabled by
577: default for >10 years. Support remains in the client.
578: <li>ssh-agent will refuse to load PKCS#11 modules outside a whitelist
579: of trusted paths by default. The path whitelist may be specified
580: at run-time.
581: <li>sshd(8): When a forced-command appears in both a certificate and
582: an authorized keys/principals command= restriction, sshd will now
583: refuse to accept the certificate unless they are identical.
584: The previous (documented) behaviour of having the certificate
585: forced-command override the other could be a bit confusing and
586: error-prone.
587: <li>sshd(8): Remove the UseLogin configuration directive and support
588: for having /bin/login manage login sessions.
589: <li>ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by the
590: version in PuTTY by Simon Tatham. This allows a multiplexing
591: client to communicate with the master process using a subset of
592: the SSH packet and channels protocol over a Unix-domain socket,
593: with the main process acting as a proxy that translates channel
594: IDs, etc. This allows multiplexing mode to run on systems that
595: lack file- descriptor passing (used by current multiplexing
596: code) and potentially, in conjunction with Unix-domain socket
597: forwarding, with the client and multiplexing master process on
598: different machines. Multiplexing proxy mode may be invoked using
599: "ssh -O proxy ..."
600: <li>sshd(8): Add a sshd_config DisableForwarding option that disables
601: X11, agent, TCP, tunnel and Unix domain socket forwarding, as well
602: as anything else we might implement in the future. Like the
603: 'restrict' authorized_keys flag, this is intended to be a simple
604: and future-proof way of restricting an account.
605: <li>sshd(8), ssh(1): Support the "curve25519-sha256" key exchange
606: method. This is identical to the currently-supported method named
607: "curve25519-sha256@libssh.org".
608: <li>sshd(8): Improve handling of SIGHUP by checking to see if sshd is
609: already daemonised at startup and skipping the call to daemon(3)
610: if it is. This ensures that a SIGHUP restart of sshd(8) will
611: retain the same process-ID as the initial execution. sshd(8) will
612: also now unlink the PidFile prior to SIGHUP restart and re-create
613: it after a successful restart, rather than leaving a stale file in
614: the case of a configuration error.
615: <li>sshd(8): Allow ClientAliveInterval and ClientAliveCountMax
616: directives to appear in sshd_config Match blocks.
617: <li>sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to match
618: those supported by AuthorizedKeysCommand (key, key type,
619: fingerprint, etc.) and a few more to provide access to the
620: contents of the certificate being offered.
621: <li>Added regression tests for string matching, address matching and
622: string sanitisation functions.
623: <li>Improved the key exchange fuzzer harness.
624: <li>Deprecate the sshd_config UsePrivilegeSeparation
625: option, thereby making privilege separation mandatory. Privilege
626: separation has been on by default for almost 15 years and
627: sandboxing has been on by default for almost the last five.
628: <li>ssh(1), sshd(8): Support "=-" syntax to easily remove methods from
629: algorithm lists, e.g. Ciphers=-*cbc.
630: </ul>
631: <li>The following significant bugs have been fixed in this release:
632: <ul>
633: <li>ssh(1): Allow IdentityFile to successfully load and use
634: certificates that have no corresponding bare public key.
635: certificate id_rsa-cert.pub (and no id_rsa.pub).
636: <li>ssh(1): Fix public key authentication when multiple
637: authentication is in use and publickey is not just the first
638: method attempted.
639: <li>ssh-agent(1), ssh(1): improve reporting when attempting to load
640: keys from PKCS#11 tokens with fewer useless log messages and more
641: detail in debug messages.
642: <li>ssh(1): When tearing down ControlMaster connections, don't
643: pollute stderr when LogLevel=quiet.
644: <li>sftp(1): On ^Z wait for underlying ssh(1) to suspend before
645: suspending sftp(1) to ensure that ssh(1) restores the terminal mode
646: correctly if suspended during a password prompt.
647: <li>ssh(1): Avoid busy-wait when ssh(1) is suspended during a password
648: prompt.
649: <li>ssh(1), sshd(8): Correctly report errors during sending of ext-
650: info messages.
651: <li>sshd(8): fix NULL-deref crash if sshd(8) received an out-of-
652: sequence NEWKEYS message.
653: <li>sshd(8): Correct list of supported signature algorithms sent in
654: the server-sig-algs extension.
655: <li>sshd(8): Fix sending ext_info message if privsep is disabled.
656: <li>sshd(8): more strictly enforce the expected ordering of privilege
657: separation monitor calls used for authentication and allow them
658: only when their respective authentication methods are enabled
659: in the configuration
660: <li>sshd(8): Fix uninitialised optlen in getsockopt() call; harmless
661: on Unix/BSD but potentially crashy on Cygwin.
662: <li>Fix false positive reports caused by explicit_bzero(3) not being
663: recognised as a memory initialiser when compiled with
664: -fsanitize-memory.
665: <li>sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet for
666: configuration examples.
667: <li>sshd(1): Fix NULL dereference crash when key exchange start
668: messages are sent out of sequence.
669: <li>ssh(1), sshd(8): Allow form-feed characters to appear in
670: configuration files.
671: <li>sshd(8): Fix regression in OpenSSH 7.4 support for the
672: server-sig-algs extension, where SHA2 RSA signature methods were
673: not being correctly advertised.
674: <li>ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in
675: known_hosts processing.
676: <li>ssh(1): Allow ssh to use certificates accompanied by a private key
677: file but no corresponding plain *.pub public key.
678: <li>ssh(1): When updating hostkeys using the UpdateHostKeys option,
679: accept RSA keys if HostkeyAlgorithms contains any RSA keytype.
680: Previously, ssh could ignore RSA keys when only the ssh-rsa-sha2-*
681: methods were enabled in HostkeyAlgorithms and not the old ssh-rsa
682: method.
683: <li>ssh(1): Detect and report excessively long configuration file
684: lines.

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

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

721: (previously incorrectly) advertised.
722: <li>sshd_config(5): Repair accidentally-deleted mention of %k token
723: in AuthorizedKeysCommand.
724: <li>sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM;
725: <li>ssh-agent(1): Relax PKCS#11 whitelist to include libexec and
726: common 32-bit compatibility library directories.
727: <li>sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME
728: response handling.
729: <li>ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted

734: <p>
735:
1.61 beck 736: <li>LibreSSL 2.5.3
1.80 deraadt 737: <ul>
738: <li>libtls now supports ALPN and SNI
739: <li>libtls adds a new callback interface for integrating custom IO
740: functions. Thanks to Tobias Pape.
741: <li>libtls now handles 4 cipher suite groups:
742: <ul>
743: <li>"secure" (TLSv1.2+AEAD+PFS)
744: <li>"compat" (HIGH:!aNULL)
745: <li>"legacy" (HIGH:MEDIUM:!aNULL)
746: <li>"insecure" (ALL:!aNULL:!eNULL)
747: </ul>
748: This allows for flexibility and finer grained control, rather than
749: having two extremes (an issue raised by Marko Kreen some time ago).
750: <li>Tightened error handling for tls_config_set_ciphers().
751: <li>libtls now always loads CA, key and certificate files at the time the
752: configuration function is called. This simplifies code and results in
753: a single memory based code path being used to provide data to libssl.
1.84 jsing 754: <li>Added support for OCSP intermediate certificates.
755: <li>Added X509_check_host(), X509_check_email(), X509_check_ip(), and
756: X509_check_ip_asc() functions, via BoringSSL.
1.80 deraadt 757: <li>Added initial support for iOS, thanks to Jacob Berkman.
758: <li>Improved behavior of arc4random on Windows when using memory leak
759: analysis software.
760: <li>Correctly handle an EOF that occurs prior to the TLS handshake
761: completing. Reported by Vasily Kolobkov, based on a diff from Marko
762: Kreen.
1.84 jsing 763: <li>Limit the support of the "backward compatible" SSLv2 handshake to
1.80 deraadt 764: only be used if TLS 1.0 is enabled.
765: <li>Fix incorrect results in certain cases on 64-bit systems when
766: BN_mod_word() can return incorrect results. BN_mod_word() now can
767: return an error condition. Thanks to Brian Smith.
1.84 jsing 768: <li>Added constant-time updates to address CVE-2016-0702.
769: <li>Fixed undefined behavior in BN_GF2m_mod_arr().
770: <li>Removed unused Cryptographic Message Support (CMS).
771: <li>More conversions of long long idioms to time_t.
1.80 deraadt 772: <li>Improved compatibility by avoiding printing NULL strings with
773: printf.
774: <li>Reverted change that cleans up the EVP cipher context in
1.84 jsing 775: EVP_EncryptFinal() and EVP_DecryptFinal(). Some software relies on the
776: previous behaviour.
1.80 deraadt 777: <li>Avoid unbounded memory growth in libssl, which can be triggered
778: by a TLS client repeatedly renegotiating and sending OCSP Status
779: Request TLS extensions.
780: <li>Avoid falling back to a weak digest for (EC)DH when using SNI
781: with libssl.
782: <li>X509_cmp_time() now passes a malformed GeneralizedTime field as
783: an error. Reported by Theofilos Petsios.
784: <li>Check for and handle failure of HMAC_{Update,Final} or
785: EVP_DecryptUpdate().
786: <li>Massive update and normalization of manpages, conversion to
787: mandoc format. Many pages were rewritten for clarity and accuracy.
788: Portable doc links are up-to-date with a new conversion tool.
1.82 jsing 789: <li>Curve25519 and TLS X25519 Key Exchange support.
1.80 deraadt 790: <li>Support for alternate chains for certificate verification.
791: <li>Code cleanups, CBB conversions, further unification of DTLS/SSL
792: handshake code, further ASN1 macro expansion and removal.
793: <li>Private symbols are now hidden in libssl and libcrypto.
794: <li>Friendly certificate verification error messages in libtls, peer
795: verification is now always enabled.
796: <li>Added OCSP stapling support to libtls and nc.
797: <li>Added ocspcheck utility to validate a certificate against its OCSP
798: responder and save the reply for stapling
799: <li>Enhanced regression tests and error handling for libtls.
800: <li>Added explicit constant and non-constant time BN functions,
801: defaulting to constant time wherever possible.
802: <li>Moved many leaked implementation details in public structs behind
803: opaque pointers.
804: <li>Added ticket support to libtls.
805: <li>Added support for setting the supported EC curves via
806: SSL{_CTX}_set1_groups{_list}() - also provide defines for the
807: previous SSL{_CTX}_set1_curves{_list} names. This also changes
808: the default list of curves to be X25519, P-256 and P-384. All
809: other curves must be manually enabled.
810: <li>Added -groups option to openssl(1) s_client for specifying the
811: curves to be used in a colon-separated list.
812: <li>Merged client/server version negotiation code paths into one,
813: reducing much duplicate code.
814: <li>Removed error function codes from libssl and libcrypto.
815: <li>Fixed an issue where a truncated packet could crash via an OOB
816: read.
817: <li>Added SSL_OP_NO_CLIENT_RENEGOTIATION option that disallows
818: client-initiated renegotiation. This is the default for libtls
819: servers.
820: <li>Avoid a side-channel cache-timing attack that can leak the ECDSA
821: private keys when signing. This is due to BN_mod_inverse() being
822: used without the constant time flag being set. Reported by Cesar
823: Pereida Garcia and Billy Brumley (Tampere University of
824: Technology). The fix was developed by Cesar Pereida Garcia.
825: <li>iOS and MacOS compatibility updates from Simone Basso and Jacob
826: Berkman.
827: <li>Added the recallocarray(3) memory allocation function, and
828: converted various places in the library to use it, such as CBB
829: and BUF_MEM_grow. recallocarray(3) is similar to
830: reallocarray. Newly allocated memory is cleared similar to
831: calloc(3). Memory that becomes unallocated while shrinking or
832: moving existing allocations is explicitly discarded by unmapping
833: or clearing to 0.
834: <li>Added new root CAs from SECOM Trust Systems / Security
835: Communication of Japan.
836: <li>Added EVP interface for MD5+SHA1 hashes.
837: <li>Improved nc(1) TLS handshake CPU usage and server-side error
838: reporting.
1.84 jsing 839: <li>Added a constant time version of BN_gcd and use it default for
1.80 deraadt 840: BN_gcd to avoid the possibility of sidechannel timing attacks
841: against RSA private key generation - Thanks to Alejandro

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.
