From djm at cvs.openbsd.org Fri Sep 13 17:43:25 2013 From: djm at cvs.openbsd.org (Damien Miller) Date: Fri, 13 Sep 2013 01:43:25 -0600 (MDT) Subject: [openssh-unix-announce] Announce: OpenSSH 6.3 released Message-ID: <201309130743.r8D7hPG5004471@cvs.openbsd.org> Changes since OpenSSH 6.2 ========================= This release is predominantly a bugfix release: Features: * sshd(8): add ssh-agent(1) support to sshd(8); allows encrypted hostkeys, or hostkeys on smartcards. * ssh(1)/sshd(8): allow optional time-based rekeying via a second argument to the existing RekeyLimit option. RekeyLimit is now supported in sshd_config as well as on the client. * sshd(8): standardise logging of information during user authentication. The presented key/cert and the remote username (if available) is now logged in the authentication success/failure message on the same log line as the local username, remote host/port and protocol in use. Certificates contents and the key fingerprint of the signing CA are logged too. Including all relevant information on a single line simplifies log analysis as it is no longer necessary to relate information scattered across multiple log entries. * ssh(1): add the ability to query which ciphers, MAC algorithms, key types and key exchange methods are supported in the binary. * ssh(1): support ProxyCommand=- to allow support cases where stdin and stdout already point to the proxy. * ssh(1): allow IdentityFile=none * ssh(1)/sshd(8): add -E option to ssh and sshd to append debugging logs to a specified file instead of stderr or syslog. * sftp(1): add support for resuming partial downloads using the "reget" command and on the sftp commandline or on the "get" commandline using the "-a" (append) option. * ssh(1): add an "IgnoreUnknown" configuration option to selectively suppress errors arising from unknown configuration directives. * sshd(8): add support for submethods to be appended to required authentication methods listed via AuthenticationMethods. Bugfixes: * sshd(8): fix refusal to accept certificate if a key of a different type to the CA key appeared in authorized_keys before the CA key. * ssh(1)/ssh-agent(1)/sshd(8): Use a monotonic time source for timers so that things like keepalives and rekeying will work properly over clock steps. * sftp(1): update progressmeter when data is acknowledged, not when it's sent. bz#2108 * ssh(1)/ssh-keygen(1): improve error messages when the current user does not exist in /etc/passwd; bz#2125 * ssh(1): reset the order in which public keys are tried after partial authentication success. * ssh-agent(1): clean up socket files after SIGINT when in debug mode; bz#2120 * ssh(1) and others: avoid confusing error messages in the case of broken system resolver configurations; bz#2122 * ssh(1): set TCP nodelay for connections started with -N; bz#2124 * ssh(1): correct manual for permission requirements on ~/.ssh/config; bz#2078 * ssh(1): fix ControlPersist timeout not triggering in cases where TCP connections have hung. bz#1917 * ssh(1): properly deatch a ControlPersist master from its controlling terminal. * sftp(1): avoid crashes in libedit when it has been compiled with multi- byte character support. bz#1990 * sshd(8): when running sshd -D, close stderr unless we have explicitly requested logging to stderr. bz#1976, * ssh(1): fix incomplete bzero; bz#2100 * sshd(8): log and error and exit if ChrootDirectory is specified and running without root privileges. * Many improvements to the regression test suite. In particular log files are now saved from ssh and sshd after failures. * Fix a number of memory leaks. bz#1967 bz#2096 and others * sshd(8): fix public key authentication when a :style is appended to the requested username. * ssh(1): do not fatally exit when attempting to cleanup multiplexing- created channels that are incompletely opened. bz#2079 Portable OpenSSH: * Major overhaul of contrib/cygwin/README * Fix unaligned accesses in umac.c for strict-alignment architectures. bz#2101 * Enable -Wsizeof-pointer-memaccess if the compiler supports it. bz#2100 * Fix broken incorrect commandline reporting errors. bz#1448 * Only include SHA256 and ECC-based key exchange methods if libcrypto has the required support. * Fix crash in SOCKS5 dynamic forwarding code on strict-alignment architectures. * A number of portability fixes for Android: * Don't try to use lastlog on Android; bz#2111 * Fall back to using openssl's DES_crypt function on platorms that don't have a native crypt() function; bz#2112 * Test for fd_mask, howmany and NFDBITS rather than trying to enumerate the plaforms that don't have them. bz#2085 * Replace S_IWRITE, which isn't standardized, with S_IWUSR, which is. bz#2085 * Add a null implementation of endgrent for platforms that don't have it (eg Android) bz#2087 * Support platforms, such as Android, that lack struct passwd.pw_gecos. bz#2086 Checksums: ========== - SHA1 (openssh-6.3.tar.gz) = 8a6ef99ffc80c19e9afe9fe1e857370f6adcf450 - SHA1 (openssh-6.3p1.tar.gz) = 70845ca79474258cab29dbefae13d93e41a83ccb Reporting Bugs: =============== - Please read http://www.openssh.com/report.html Security bugs should be reported directly to openssh at openssh.com OpenSSH is brought to you by Markus Friedl, Niels Provos, Theo de Raadt, Kevin Steves, Damien Miller, Darren Tucker, Jason McIntyre, Tim Rice and Ben Lindstrom.
