2011-09-06* New upstream release (http://www.openssh.org/txt/release-5.9).Colin Watson
- Introduce sandboxing of the pre-auth privsep child using an optional sshd_config(5) "UsePrivilegeSeparation=sandbox" mode that enables mandatory restrictions on the syscalls the privsep child can perform. - Add new SHA256-based HMAC transport integrity modes from http://www.ietf.org/id/draft-dbider-sha2-mac-for-ssh-02.txt. - The pre-authentication sshd(8) privilege separation slave process now logs via a socket shared with the master process, avoiding the need to maintain /dev/log inside the chroot (closes: #75043, #429243, #599240). - ssh(1) now warns when a server refuses X11 forwarding (closes: #504757). - sshd_config(5)'s AuthorizedKeysFile now accepts multiple paths, separated by whitespace (closes: #76312). The authorized_keys2 fallback is deprecated but documented (closes: #560156). - ssh(1) and sshd(8): set IPv6 traffic class from IPQoS, as well as IPv4 ToS/DSCP (closes: #498297). - ssh-add(1) now accepts keys piped from standard input. E.g. "ssh-add - < /path/to/key" (closes: #229124). - Clean up lost-passphrase text in ssh-keygen(1) (closes: #444691). - Say "required" rather than "recommended" in unprotected-private-key warning (LP: #663455).

2010-08-23* New upstream release (http://www.openssh.com/txt/release-5.6):Colin Watson
- Added a ControlPersist option to ssh_config(5) that automatically starts a background ssh(1) multiplex master when connecting. This connection can stay alive indefinitely, or can be set to automatically close after a user-specified duration of inactivity (closes: #335697, #350898, #454787, #500573, #550262). - Support AuthorizedKeysFile, AuthorizedPrincipalsFile, HostbasedUsesNameFromPacketOnly, and PermitTunnel in sshd_config(5) Match blocks (closes: #549858). - sftp(1): fix ls in working directories that contain globbing characters in their pathnames (LP: #530714).

[auth.c auth2-hostbased.c authfile.c authfile.h ssh-keysign.8] [ssh-keysign.c ssh.c] enable certificates for hostbased authentication, from Iain Morgan; "looks ok" markus@
2010-03-31* New upstream release (LP: #535029).Colin Watson
- After a transition period of about 10 years, this release disables SSH protocol 1 by default. Clients and servers that need to use the legacy protocol must explicitly enable it in ssh_config / sshd_config or on the command-line. - Remove the libsectok/OpenSC-based smartcard code and add support for PKCS#11 tokens. This support is enabled by default in the Debian packaging, since it now doesn't involve additional library dependencies (closes: #231472, LP: #16918). - Add support for certificate authentication of users and hosts using a new, minimal OpenSSH certificate format (closes: #482806). - Added a 'netcat mode' to ssh(1): "ssh -W host:port ...". - Add the ability to revoke keys in sshd(8) and ssh(1). (For the Debian package, this overlaps with the key blacklisting facility added in openssh 1:4.7p1-9, but with different file formats and slightly different scopes; for the moment, I've roughly merged the two.) - Various multiplexing improvements, including support for requesting port-forwardings via the multiplex protocol (closes: #360151). - Allow setting an explicit umask on the sftp-server(8) commandline to override whatever default the user has (closes: #496843). - Many sftp client improvements, including tab-completion, more options, and recursive transfer support for get/put (LP: #33378). The old mget/mput commands never worked properly and have been removed (closes: #270399, #428082). - Do not prompt for a passphrase if we fail to open a keyfile, and log the reason why the open failed to debug (closes: #431538). - Prevent sftp from crashing when given a "-" without a command. Also, allow whitespace to follow a "-" (closes: #531561).

Add a RevokedKeys option to sshd_config and a @revoked marker to known_hosts to allow keys to me revoked and banned for user or host authentication. feedback and ok markus@

reject_blacklisted_key function in auth.c (thanks, Dmitry V. Levin).
2008-05-25Check for blacklists in /usr/share/ssh/ as well as /etc/ssh/ (seeColin Watson
#481283).
2008-05-12* Mitigate OpenSSL security vulnerability:Colin Watson
- Add key blacklisting support. Keys listed in /etc/ssh/blacklist.TYPE-LENGTH will be rejected for authentication by sshd, unless "PermitBlacklistedKeys yes" is set in /etc/ssh/sshd_config. - Add a new program, ssh-vulnkey, which can be used to check keys against these blacklists. - Depend on openssh-blacklist. - Force dependencies on libssl0.9.8 / libcrypto0.9.8-udeb to at least 0.9.8g-9. - Automatically regenerate known-compromised host keys, with a critical-priority debconf note. (I regret that there was no time to gather translations.)

[authfile.c authfile.h pathnames.h ssh.c sshconnect.c sshconnect.h sshconnect1.c sshconnect2.c ssh-keysign.8 ssh-keysign.c Makefile.in] add /usr/libexec/ssh-keysign: a setuid helper program for hostbased authentication in protocol v2 (needs to access the hostkeys).
