Update security/openssh to 7.5p1.

Potentially-incompatible changes

This release includes a number of changes that may affect existing

 * This release deprecates the sshd_config UsePrivilegeSeparation
   option, thereby making privilege separation mandatory. Privilege
   separation has been on by default for almost 15 years and
   sandboxing has been on by default for almost the last five.

 * The format of several log messages emitted by the packet code has
   changed to include additional information about the user and
   their authentication state. Software that monitors ssh/sshd logs
   may need to account for these changes. For example:

   Connection closed by user x port 1234 [preauth]
   Connection closed by authenticating user x port 1234 [preauth]
   Connection closed by invalid user x port 1234 [preauth]

   Affected messages include connection closure, timeout, remote
   disconnection, negotiation failure and some other fatal messages
   generated by the packet code.

 * [Portable OpenSSH only] This version removes support for building
   against OpenSSL versions prior to 1.0.1. OpenSSL stopped supporting
   versions prior to 1.0.1 over 12 months ago (i.e. they no longer
   receive fixes for security bugs).

Changes since OpenSSH 7.4

This is a bugfix release.


 * ssh(1), sshd(8): Fix weakness in CBC padding oracle countermeasures
   that allowed a variant of the attack fixed in OpenSSH 7.3 to proceed.
   Note that the OpenSSH client disables CBC ciphers by default, sshd
   offers them as lowest-preference options and will remove them by
   default entriely in the next release. Reported by Jean Paul
   Degabriele, Kenny Paterson, Martin Albrecht and Torben Hansen of
   Royal Holloway, University of London.

 * sftp-client(1): [portable OpenSSH only] On Cygwin, a client making
   a recursive file transfer could be maniuplated by a hostile server to
   perform a path-traversal attack. creating or modifying files outside
   of the intended target directory. Reported by Jann Horn of Google
   Project Zero.

New Features

 * ssh(1), sshd(8): Support "=-" syntax to easily remove methods from
   algorithm lists, e.g. Ciphers=-*cbc. bz#2671


 * sshd(1): Fix NULL dereference crash when key exchange start
   messages are sent out of sequence.

 * ssh(1), sshd(8): Allow form-feed characters to appear in
   configuration files.

 * sshd(8): Fix regression in OpenSSH 7.4 support for the
   server-sig-algs extension, where SHA2 RSA signature methods were
   not being correctly advertised. bz#2680

 * ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in
   known_hosts processing. bz#2591 bz#2685

 * ssh(1): Allow ssh to use certificates accompanied by a private key
   file but no corresponding plain *.pub public key. bz#2617

 * ssh(1): When updating hostkeys using the UpdateHostKeys option,
   accept RSA keys if HostkeyAlgorithms contains any RSA keytype.
   Previously, ssh could ignore RSA keys when only the ssh-rsa-sha2-*
   methods were enabled in HostkeyAlgorithms and not the old ssh-rsa
   method. bz#2650

 * ssh(1): Detect and report excessively long configuration file
   lines. bz#2651

 * Merge a number of fixes found by Coverity and reported via Redhat
   and FreeBSD. Includes fixes for some memory and file descriptor
   leaks in error paths. bz#2687

 * ssh-keyscan(1): Correctly hash hosts with a port number. bz#2692

 * ssh(1), sshd(8): When logging long messages to stderr, don't truncate
   "\r\n" if the length of the message exceeds the buffer. bz#2688

 * ssh(1): Fully quote [host]:port in generated ProxyJump/-J command-
   line; avoid confusion over IPv6 addresses and shells that treat
   square bracket characters specially.

 * ssh-keygen(1): Fix corruption of known_hosts when running
   "ssh-keygen -H" on a known_hosts containing already-hashed entries.

 * Fix various fallout and sharp edges caused by removing SSH protocol
   1 support from the server, including the server banner string being
   incorrectly terminated with only \n (instead of \r\n), confusing
   error messages from ssh-keyscan bz#2583 and a segfault in sshd
   if protocol v.1 was enabled for the client and sshd_config
   contained references to legacy keys bz#2686.

 * ssh(1), sshd(8): Free fd_set on connection timeout. bz#2683

 * sshd(8): Fix Unix domain socket forwarding for root (regression in
   OpenSSH 7.4).

 * sftp(1): Fix division by zero crash in "df" output when server
   returns zero total filesystem blocks/inodes.

 * ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors
   encountered during key loading to more meaningful error codes.
   bz#2522 bz#2523

 * ssh-keygen(1): Sanitise escape sequences in key comments sent to
   printf but preserve valid UTF-8 when the locale supports it;

 * ssh(1), sshd(8): Return reason for port forwarding failures where
   feasible rather than always "administratively prohibited". bz#2674

 * sshd(8): Fix deadlock when AuthorizedKeysCommand or
   AuthorizedPrincipalsCommand produces a lot of output and a key is
   matched early. bz#2655

 * Regression tests: several reliability fixes. bz#2654 bz#2658 bz#2659

 * ssh(1): Fix typo in ~C error message for bad port forward
   cancellation. bz#2672

 * ssh(1): Show a useful error message when included config files
   can't be opened; bz#2653

 * sshd(8): Make sshd set GSSAPIStrictAcceptorCheck=yes as the manual page
   (previously incorrectly) advertised. bz#2637

 * sshd_config(5): Repair accidentally-deleted mention of %k token
   in AuthorizedKeysCommand; bz#2656

 * sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM; bz#2665

 * ssh-agent(1): Relax PKCS#11 whitelist to include libexec and
   common 32-bit compatibility library directories.

 * sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME
   response handling.

 * ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted
   keys. It was not possible to delete them except by specifying
   their full physical path. bz#2682


 * sshd(8): Avoid sandbox errors for Linux S390 systems using an ICA
   crypto coprocessor.

 * sshd(8): Fix non-exploitable weakness in seccomp-bpf sandbox arg

 * ssh(1): Fix X11 forwarding on OSX where X11 was being started by
   launchd. bz#2341

 * ssh-keygen(1), ssh(1), sftp(1): Fix output truncation for various that
   contain non-printable characters where the codeset in use is ASCII.

 * build: Fix builds that attempt to link a kerberised libldns. bz#2603

 * build: Fix compilation problems caused by unconditionally defining
   _XOPEN_SOURCE in wide character detection.

 * sshd(8): Fix sandbox violations for clock_gettime VSDO syscall
   fallback on some Linux/X32 kernels. bz#2142
