        !           568:           refuse to accept the certificate unless they are identical.
        !           569:           The previous (documented) behaviour of having the certificate
        !           570:           forced-command override the other could be a bit confusing and
        !           571:           error-prone.
        !           572:       <li>sshd(8): Remove the UseLogin configuration directive and support
        !           573:           for having /bin/login manage login sessions.
        !           574:       <li>ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by the
        !           575:           version in PuTTY by Simon Tatham. This allows a multiplexing
        !           576:           client to communicate with the master process using a subset of
        !           577:           the SSH packet and channels protocol over a Unix-domain socket,
        !           578:           with the main process acting as a proxy that translates channel
        !           579:           IDs, etc.  This allows multiplexing mode to run on systems that
        !           580:           lack file- descriptor passing (used by current multiplexing
        !           581:           code) and potentially, in conjunction with Unix-domain socket
        !           582:           forwarding, with the client and multiplexing master process on
        !           583:           different machines. Multiplexing proxy mode may be invoked using
        !           584:           "ssh -O proxy ..."
        !           585:       <li>sshd(8): Add a sshd_config DisableForwarding option that disables
        !           586:           X11, agent, TCP, tunnel and Unix domain socket forwarding, as well
        !           587:           as anything else we might implement in the future. Like the
        !           588:           'restrict' authorized_keys flag, this is intended to be a simple
        !           589:           and future-proof way of restricting an account.
        !           590:       <li>sshd(8), ssh(1): Support the "curve25519-sha256" key exchange
        !           591:           method. This is identical to the currently-supported method named
        !           592:           "curve25519-sha256@libssh.org".
        !           593:       <li>sshd(8): Improve handling of SIGHUP by checking to see if sshd is
        !           594:           already daemonised at startup and skipping the call to daemon(3)
        !           595:           if it is. This ensures that a SIGHUP restart of sshd(8) will
        !           596:           retain the same process-ID as the initial execution. sshd(8) will
        !           597:           also now unlink the PidFile prior to SIGHUP restart and re-create
        !           598:           it after a successful restart, rather than leaving a stale file in
        !           599:           the case of a configuration error.
        !           600:       <li>sshd(8): Allow ClientAliveInterval and ClientAliveCountMax
        !           601:           directives to appear in sshd_config Match blocks.
        !           602:       <li>sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to match
        !           603:           those supported by AuthorizedKeysCommand (key, key type,
        !           604:           fingerprint, etc.) and a few more to provide access to the
        !           605:           contents of the certificate being offered.
        !           606:       <li>Added regression tests for string matching, address matching and
        !           607:           string sanitisation functions.
        !           608:       <li>Improved the key exchange fuzzer harness.
        !           609:       <li>Deprecate the sshd_config UsePrivilegeSeparation
        !           610:           option, thereby making privilege separation mandatory. Privilege
        !           611:           separation has been on by default for almost 15 years and
        !           612:           sandboxing has been on by default for almost the last five.
        !           613:       <li>ssh(1), sshd(8): Support "=-" syntax to easily remove methods from
        !           614:           algorithm lists, e.g. Ciphers=-*cbc.
        !           615:       </ul>
        !           616:     <li>The following significant bugs have been fixed in this release:
        !           617:       <ul>
        !           618:       <li>ssh(1): Allow IdentityFile to successfully load and use

        !           621:       <li>ssh(1): Fix public key authentication when multiple
        !           622:           authentication is in use and publickey is not just the first

        !           624:       <li>ssh-agent(1), ssh(1): improve reporting when attempting to load
        !           625:           keys from PKCS#11 tokens with fewer useless log messages and more
        !           626:           detail in debug messages.
        !           627:       <li>ssh(1): When tearing down ControlMaster connections, don't

        !           630:           suspending sftp(1) to ensure that ssh(1) restores the terminal mode
        !           631:           correctly if suspended during a password prompt.
        !           632:       <li>ssh(1): Avoid busy-wait when ssh(1) is suspended during a password
        !           633:           prompt.
        !           634:       <li>ssh(1), sshd(8): Correctly report errors during sending of ext-
        !           635:           info messages.

        !           641:       <li>sshd(8): more strictly enforce the expected ordering of privilege
        !           642:           separation monitor calls used for authentication and allow them
        !           643:           only when their respective authentication methods are enabled
        !           644:           in the configuration
        !           645:       <li>sshd(8): Fix uninitialised optlen in getsockopt() call; harmless
        !           646:           on Unix/BSD but potentially crashy on Cygwin.
        !           647:       <li>Fix false positive reports caused by explicit_bzero(3) not being
        !           648:           recognised as a memory initialiser when compiled with

        !           657:           server-sig-algs extension, where SHA2 RSA signature methods were
        !           658:           not being correctly advertised.
        !           659:       <li>ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in
        !           660:           known_hosts processing.
        !           661:       <li>ssh(1): Allow ssh to use certificates accompanied by a private key
        !           662:           file but no corresponding plain *.pub public key.

        !           664:           accept RSA keys if HostkeyAlgorithms contains any RSA keytype.
        !           665:           Previously, ssh could ignore RSA keys when only the ssh-rsa-sha2-*
        !           666:           methods were enabled in HostkeyAlgorithms and not the old ssh-rsa
        !           667:           method.
        !           668:       <li>ssh(1): Detect and report excessively long configuration file

        !           679:       <li>ssh-keygen(1): Fix corruption of known_hosts when running
        !           680:           "ssh-keygen -H" on a known_hosts containing already-hashed entries.
        !           681:       <li>Fix various fallout and sharp edges caused by removing SSH protocol
        !           682:           1 support from the server, including the server banner string being
        !           683:           incorrectly terminated with only \n (instead of \r\n), confusing
        !           684:           error messages from ssh-keyscan a segfault in sshd
        !           685:           if protocol v.1 was enabled for the client and sshd_config
        !           686:           contained references to legacy keys.
        !           687:       <li>ssh(1), sshd(8): Free fd_set on connection timeout.
        !           688:       <li>sshd(8): Fix Unix domain socket forwarding for root (regression in
        !           689:           OpenSSH 7.4).
        !           690:       <li>sftp(1): Fix division by zero crash in "df" output when server
        !           691:           returns zero total filesystem blocks/inodes.
        !           692:       <li>ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors
        !           693:           encountered during key loading to more meaningful error codes.
        !           694:       <li>ssh-keygen(1): Sanitise escape sequences in key comments sent to
        !           695:           printf but preserve valid UTF-8 when the locale supports it.
        !           696:       <li>ssh(1), sshd(8): Return reason for port forwarding failures where
        !           697:           feasible rather than always "administratively prohibited".
        !           698:       <li>sshd(8): Fix deadlock when AuthorizedKeysCommand or
        !           699:           AuthorizedPrincipalsCommand produces a lot of output and a key is
        !           700:           matched early.
        !           701:       <li>ssh(1): Fix typo in ~C error message for bad port forward

        !           704:           can't be opened.
        !           705:       <li>sshd(8): Make sshd set GSSAPIStrictAcceptorCheck=yes as the manual page

        !           707:       <li>sshd_config(5): Repair accidentally-deleted mention of %k token
        !           708:           in AuthorizedKeysCommand.
        !           709:       <li>sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM;
        !           710:       <li>ssh-agent(1): Relax PKCS#11 whitelist to include libexec and
        !           711:           common 32-bit compatibility library directories.
        !           712:       <li>sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME
        !           713:           response handling.
        !           714:       <li>ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted
        !           715:           keys. It was not possible to delete them except by specifying
        !           716:           their full physical path.

                    722:   <ul>
                    723:
                    724:   <li> libtls now supports ALPN and SNI
                    725:
                    726:   <li> libtls adds a new callback interface for integrating custom IO
                    727:     functions. Thanks to Tobias Pape.
                    728:
                    729:   <li> libtls now handles 4 cipher suite groups:
                    730:     <Ul>
                    731:       <li> "secure" (TLSv1.2+AEAD+PFS)
                    732:       <li> "compat" (HIGH:!aNULL)
                    733:       <li> "legacy" (HIGH:MEDIUM:!aNULL)
                    734:       <li> "insecure" (ALL:!aNULL:!eNULL)
                    735:     </ul>
                    736:       This allows for flexibility and finer grained control, rather than
                    737:       having two extremes (an issue raised by Marko Kreen some time ago).
                    738:
                    739:   <li> Tightened error handling for tls_config_set_ciphers().
                    740:
                    741:   <li> libtls now always loads CA, key and certificate files at the time the
                    742:     configuration function is called. This simplifies code and results in
                    743:     a single memory based code path being used to provide data to libssl.
                    744:
                    745:   <li> Add support for OCSP intermediate certificates.
                    746:
                    747:   <li> Added functions used by stunnel and exim from BoringSSL - this
                    748:     brings in X509_check_host, X509_check_email, X509_check_ip, and
                    749:     X509_check_ip_asc.
                    750:
                    751:   <li> Added initial support for iOS, thanks to Jacob Berkman.
                    752:
                    753:   <li> Improved behavior of arc4random on Windows when using memory leak
                    754:     analysis software.
                    755:

                    757:     completing. Reported by Vasily Kolobkov, based on a diff from Marko
                    758:     Kreen.
                    759:
                    760:   <li> Limit the support of the "backward compatible" ssl2 handshake to
                    761:     only be used if TLS 1.0 is enabled.
                    762:
                    763:   <li> Fix incorrect results in certain cases on 64-bit systems when

                    832:       previous SSL{_CTX}_set1_curves{_list} names. This also changes
                    833:       the default list of curves to be X25519, P-256 and P-384. All
                    834:       other curves must be manually enabled.
                    835:
                    836:  <li> Added -groups option to openssl(1) s_client for specifying the

                    846:
                    847:  <li> Added SSL_OP_NO_CLIENT_RENEGOTIATION option that disallows
                    848:       client-initiated renegotiation. This is the default for libtls
                    849:       servers.
                    850:
                    851:  <li> Avoid a side-channel cache-timing attack that can leak the ECDSA
                    852:       private keys when signing. This is due to BN_mod_inverse() being
                    853:       used without the constant time flag being set. Reported by Cesar
                    854:       Pereida Garcia and Billy Brumley (Tampere University of
                    855:       Technology).  The fix was developed by Cesar Pereida Garcia.

                    857:  <li> iOS and MacOS compatibility updates from Simone Basso and Jacob
                    858:       Berkman.
                    859:
                    860:  <li> Added the recallocarray(3) memory allocation function, and
                    861:       converted various places in the library to use it, such as CBB
                    862:       and BUF_MEM_grow.  recallocarray(3) is similar to
                    863:       reallocarray. Newly allocated memory is cleared similar to
                    864:       calloc(3). Memory that becomes unallocated while shrinking or
                    865:       moving existing allocations is explicitly discarded by unmapping
                    866:       or clearing to 0.
                    867:
                    868:  <li> Added new root CAs from SECOM Trust Systems / Security
                    869:       Communication of Japan.
                    870:
                    871:  <li> Added EVP interface for MD5+SHA1 hashes.
                    872:
                    873:  <li> Fixed DTLS client failures when the server sends a certificate
                    874:       request.
                    875:
                    876:  <li> Correct handling of padding when upgrading an SSLv2 challenge
                    877:       into an SSLv3/TLS connection.
                    878:
                    879:  <li> Allow protocols and ciphers to be set on a TLS config object in
                    880:       libtls.
                    881:
                    882:  <li> Improved nc(1) TLS handshake CPU usage and server-side error
1.65      beck      883:    reporting.
                    884:
                    885:  <li> Add a constant time version of BN_gcd and use it default for
                    886:    BN_gcd to avoid the possibility of sidechannel timing attacks
                    887:    against RSA private key generation - Thanks to Alejandro
