2015-09-17Various 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 and disable GSSAPIDelegateCredentials by default. sshd: Refer to /usr/share/doc/openssh-server/README.Debian.gz alongside PermitRootLogin default. Document all of this, along with several sshd defaults set in debian/openssh-server.postinst.

2015-09-17Don'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.

2015-09-17ssh(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).

Apparently this breaks some SVR4 packaging systems, so upstream can't win either way and opted to keep the status quo. We need this patch anyway. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1728 Last-Update: 2013-09-14 Patch-Name: lintian-symlink-pickiness.patch

2015-09-17Add DebianBanner server configuration optionKees Cook
Setting this to "no" causes sshd to omit the Debian revision from its initial protocol handshake, for those scared by package-versioning.patch. Bug-Debian: http://bugs.debian.org/562048 Forwarded: not-needed Last-Update: 2015-08-19 Patch-Name: debian-banner.patch
2015-09-17Include 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.)

2015-09-17Look for $SHELL on the path for ProxyCommand/LocalCommandColin Watson
There's some debate on the upstream bug about whether POSIX requires this. I (Colin Watson) agree with Vincent and think it does. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1494 Bug-Debian: http://bugs.debian.org/492728 Last-Update: 2013-09-14 Patch-Name: shell-path.patch

2015-09-17Allow 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.

2015-09-17Reduce severity of "Killed by signal %d"Peter Samuelson
This produces irritating messages when using ProxyCommand or other programs that use ssh under the covers (e.g. Subversion). These messages are more normally printed by the calling program, such as the shell. According to the upstream bug, the right way to avoid this is to use the -q option, so we may drop this patch after further investigation into whether any software in Debian is still relying on it. Author: Colin Watson <cjwatson@debian.org> Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1118 Bug-Debian: http://bugs.debian.org/313371 Last-Update: 2013-09-14 Patch-Name: quieter-signals.patch
2015-09-17"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. Author: Matthew Vernon <matthew@debian.org> Author: Colin Watson <cjwatson@debian.org> Last-Update: 2013-09-14 Patch-Name: syslog-level-silent.patch
2015-09-17Various 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.

2015-09-17Accept 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. Last-Update: 2014-02-09 Patch-Name: ssh-vulnkey-compat.patch
2015-09-17Handle 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: 2015-08-19 Patch-Name: selinux-role.patch
2015-09-17Restore 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: 2014-10-07 Patch-Name: restore-tcp-wrappers.patch
2015-09-17GSSAPI 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: 2015-09-17 Patch-Name: gssapi.patch
