unbreak authentication using lone certificate keys in ssh-agent: when attempting pubkey auth with a certificate, if no separate private key is found among the keys then try with the certificate key itself. bz#2550 reported by Peter Moody Upstream-ID: f939cd76d68e6a9a3d1711b5a943d6ed1e623966 Origin: upstream, https://anongit.mindrot.org/openssh.git/commit/?id=c38905ba391434834da86abfc988a2b8b9b62477 Bug-Ubuntu: https://bugs.launchpad.net/bugs/1575961 Last-Update: 2016-04-28 Patch-Name: unbreak-certificate-auth.patch
2016-04-13ignore PAM environment vars when UseLogin=yesDamien Miller
If PAM is configured to read user-specified environment variables and UseLogin=yes in sshd_config, then a hostile local user may attack /bin/login via LD_PRELOAD or similar environment variables set via PAM. CVE-2015-8325, found by Shayan Sadigh, via Colin Watson Origin: upstream, https://anongit.mindrot.org/openssh.git/commit/?id=85bdcd7c92fe7ff133bbc4e10a65c91810f88755 Last-Update: 2016-04-13 Patch-Name: CVE-2015-8325.patch
2016-03-21Various 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. Document all of this, along with several sshd defaults set in debian/openssh-server.postinst.

2016-03-21Don'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.

2016-03-21ssh(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).

This makes it easier to audit networks for versions patched against security vulnerabilities.

2016-03-21Allow 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.

2016-03-21Reduce 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.

2016-03-21"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.

2016-03-21Various 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.

2016-03-21Accept 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.

2016-03-21Handle 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.

2016-03-21Restore 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
2016-03-21GSSAPI 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: 2016-03-21 Patch-Name: gssapi.patch

2016-02-23Disable tests where fs perms are incorrectDamien Miller
Some tests have strict requirements on the filesystem permissions for certain files and directories. This adds a regress/check-perm tool that copies the relevant logic from sshd to exactly test the paths in question. This lets us skip tests when the local filesystem doesn't conform to our expectations rather than continuing and failing the test run. ok dtucker@
