2018-10-20Restore reading authorized_keys2 by defaultColin Watson
Upstream seems to intend to gradually phase this out, so don't assume that this will remain the default forever. However, we were late in adopting the upstream sshd_config changes, so it makes sense to extend the grace period.

2018-10-20Various Debian-specific configuration changesColin Watson
ssh: Enable ForwardX11Trusted, returning to earlier semantics which cause fewer problems with existing setups (http://bugs.debian.org/237021). ssh: Set 'SendEnv LANG LC_*' by default (http://bugs.debian.org/264024). ssh: Enable HashKnownHosts by default to try to limit the spread of ssh worms. ssh: Enable GSSAPIAuthentication by default. sshd: Enable PAM, disable ChallengeResponseAuthentication, and disable PrintMotd. sshd: Enable X11Forwarding. sshd: Set 'AcceptEnv LANG LC_*' by default. sshd: Change sftp subsystem path to /usr/lib/openssh/sftp-server.

2018-10-20Don't check the status field of the OpenSSL versionKurt Roeckx
There is no reason to check the version of OpenSSL (in Debian). If it's not compatible the soname will change. OpenSSH seems to want to do a check for the soname based on the version number, but wants to keep the status of the release the same. Remove that check on the status since it doesn't tell you anything about how compatible that version is.

2018-10-20ssh(1): Refer to ssh-argv0(1)Colin Watson
Old versions of OpenSSH (up to 2.5 or thereabouts) allowed creating symlinks to ssh with the name of the host you want to connect to. Debian ships an ssh-argv0 script restoring this feature; this patch refers to its manual page from ssh(1).

2018-10-20Include the Debian version in our identificationMatthew Vernon
This makes it easier to audit networks for versions patched against security vulnerabilities. It has little detrimental effect, as attackers will generally just try attacks rather than bothering to scan for vulnerable-looking version strings. (However, see debian-banner.patch.)

2018-10-20Allow harmless group-writabilityColin Watson
Allow secure files (~/.ssh/config, ~/.ssh/authorized_keys, etc.) to be group-writable, provided that the group in question contains only the file's owner. Rejected upstream for IMO incorrect reasons (e.g. a misunderstanding about the contents of gr->gr_mem). Given that per-user groups and umask 002 are the default setup in Debian (for good reasons - this makes operating in setgid directories with other groups much easier), we need to permit this by default.

2018-10-20"LogLevel SILENT" compatibilityJonathan David Amery
"LogLevel SILENT" (-qq) was introduced in Debian openssh 1:3.0.1p1-1 to match the behaviour of non-free SSH, in which -q does not suppress fatal errors. However, this was unintentionally broken in 1:4.6p1-2 and nobody complained, so we've dropped most of it. The parts that remain are basic configuration file compatibility, and an adjustment to "Pseudo-terminal will not be allocated ..." which should be split out into a separate patch.

2018-10-20Various keepalive extensionsRichard Kettlewell
Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported in previous versions of Debian's OpenSSH package but since superseded by ServerAliveInterval. (We're probably stuck with this bit for compatibility.) In batch mode, default ServerAliveInterval to five minutes. Adjust documentation to match and to give some more advice on use of keepalives.

2018-10-20Accept obsolete ssh-vulnkey configuration optionsColin Watson
These options were used as part of Debian's response to CVE-2008-0166. Nearly six years later, we no longer need to continue carrying the bulk of that patch, but we do need to avoid failing when the associated configuration options are still present.

2018-10-20Handle SELinux authorisation rolesManoj Srivastava
Rejected upstream due to discomfort with magic usernames; a better approach will need an SSH protocol change. In the meantime, this came from Debian's SELinux maintainer, so we'll keep it until we have something better. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1641 Bug-Debian: http://bugs.debian.org/394795 Last-Update: 2018-08-24 Patch-Name: selinux-role.patch
2018-10-20Restore TCP wrappers supportColin Watson
Support for TCP wrappers was dropped in OpenSSH 6.7. See this message and thread: https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-April/032497.html It is true that this reduces preauth attack surface in sshd. On the other hand, this support seems to be quite widely used, and abruptly dropping it (from the perspective of users who don't read openssh-unix-dev) could easily cause more serious problems in practice. It's not entirely clear what the right long-term answer for Debian is, but it at least probably doesn't involve dropping this feature shortly before a freeze. Forwarded: not-needed Last-Update: 2018-08-24 Patch-Name: restore-tcp-wrappers.patch
2018-10-20GSSAPI key exchange supportSimon Wilkinson
This patch has been rejected upstream: "None of the OpenSSH developers are in favour of adding this, and this situation has not changed for several years. This is not a slight on Simon's patch, which is of fine quality, but just that a) we don't trust GSSAPI implementations that much and b) we don't like adding new KEX since they are pre-auth attack surface. This one is particularly scary, since it requires hooks out to typically root-owned system resources." However, quite a lot of people rely on this in Debian, and it's better to have it merged into the main openssh package rather than having separate -krb5 packages (as we used to have). It seems to have a generally good security history. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1242 Last-Updated: 2018-10-20 Patch-Name: gssapi.patch

2018-10-11supply callback to PEM_read_bio_PrivateKeyDamien Miller
OpenSSL 1.1.0i has changed the behaviour of their PEM APIs, so that empty passphrases are interpreted differently. This probabalistically breaks loading some keys, because the PEM format is terrible and doesn't include a proper MAC. Avoid this by providing a basic callback to avoid passing empty passphrases to OpenSSL in cases where one is required. Based on patch from Jakub Jelen in bz#2913; ok dtucker@
