- upgrade to 7.6p1
see main package changelog for details
- Update to vanilla 7.6p1
Most important changes (more details below):
* complete removal of the ancient SSHv1 protocol
* sshd(8) cannot run without privilege separation
* removal of suport for arcfourm blowfish and CAST ciphers
and RIPE-MD160 HMAC
* refuse RSA keys shorter than 1024 bits
Distilled upstream log:
- OpenSSH 7.3
---- Security
* sshd(8): Mitigate a potential denial-of-service attack
against the system's crypt(3) function via sshd(8). An
attacker could send very long passwords that would cause
excessive CPU use in crypt(3). sshd(8) now refuses to accept
password authentication requests of length greater than 1024
characters. Independently reported by Tomas Kuthan (Oracle),
Andres Rojas and Javier Nieto.
* sshd(8): Mitigate timing differences in password
authentication that could be used to discern valid from
invalid account names when long passwords were sent and
particular password hashing algorithms are in use on the
server. CVE-2016-6210, reported by EddieEzra.Harari at
verint.com
* ssh(1), sshd(8): Fix observable timing weakness in the CBC
padding oracle countermeasures. Reported by Jean Paul
Degabriele, Kenny Paterson, Torben Hansen and Martin
Albrecht. Note that CBC ciphers are disabled by default and

upstream package without any SUSE patches
Distilled upstream log:
- OpenSSH 6.7
Potentially-incompatible changes:
* sshd(8): The default set of ciphers and MACs has been
altered to remove unsafe algorithms. In particular, CBC
ciphers and arcfour* are disabled by default.
The full set of algorithms remains available if configured
explicitly via the Ciphers and MACs sshd_config options.
* sshd(8): Support for tcpwrappers/libwrap has been removed.
* OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of
connections using the curve25519-sha256@libssh.org KEX
exchange method to fail when connecting with something that
implements the specification correctly. OpenSSH 6.7 disables
this KEX method when speaking to one of the affected
versions.
New Features:
* ssh(1), sshd(8): Add support for Unix domain socket
forwarding. A remote TCP port may be forwarded to a local
Unix domain socket and vice versa or both ends may be a Unix
domain socket.
* ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for
ED25519 key types.

- Update of the underlying OpenSSH to 6.6p1
- update to 6.6p1
Security:
* sshd(8): when using environment passing with a sshd_config(5)
AcceptEnv pattern with a wildcard. OpenSSH prior to 6.6 could
be tricked into accepting any enviornment variable that
contains the characters before the wildcard character.
Features since 6.5p1:
* ssh(1), sshd(8): removal of the J-PAKE authentication code,
which was experimental, never enabled and has been
unmaintained for some time.
* ssh(1): skip 'exec' clauses other clauses predicates failed
to match while processing Match blocks.
* ssh(1): if hostname canonicalisation is enabled and results
in the destination hostname being changed, then re-parse
ssh_config(5) files using the new destination hostname. This
gives 'Host' and 'Match' directives that use the expanded
hostname a chance to be applied.
Bugfixes:
* ssh(1): avoid spurious "getsockname failed: Bad file
descriptor" in ssh -W. bz#2200, debian#738692
* sshd(8): allow the shutdown(2) syscall in seccomp-bpf and
systrace sandbox modes, as it is reachable if the connection
is terminated during the pre-auth phase.
* ssh(1), sshd(8): fix unsigned overflow that in SSH protocol 1
bignum parsing. Minimum key length checks render this bug
unexploitable to compromise SSH 1 sessions.
* sshd_config(5): clarify behaviour of a keyword that appears
in multiple matching Match blocks. bz#2184

- Update of the underlying OpenSSH to 6.5p1
- Update to 6.5p1
Features since 6.4p1:
* ssh(1), sshd(8): support for key exchange using ECDH in
Daniel Bernstein's Curve25519; default when both the client
and server support it.
* ssh(1), sshd(8): support for Ed25519 as a public key type fo
rboth server and client. Ed25519 is an EC signature offering
better security than ECDSA and DSA and good performance.
* Add a new private key format that uses a bcrypt KDF to better
protect keys at rest. Used unconditionally for Ed25519 keys,
on demand for other key types via the -o ssh-keygen(1)
option. Intended to become default in the near future.
Details documented in PROTOCOL.key.
* ssh(1), sshd(8): new transport cipher
"chacha20-poly1305@openssh.com" combining Daniel Bernstein's
ChaCha20 stream cipher and Poly1305 MAC to build an
authenticated encryption mode. Details documented
PROTOCOL.chacha20poly1305.
* ssh(1), sshd(8): refuse RSA keys from old proprietary clients
and servers that use the obsolete RSA+MD5 signature scheme.
It will still be possible to connect with these
clients/servers but only DSA keys will be accepted, and
OpenSSH will refuse connection entirely in a future release.
* ssh(1), sshd(8): refuse old proprietary clients and servers
that use a weaker key exchange hash calculation.
* ssh(1): increase the size of the Diffie-Hellman groups
requested for each symmetric key size. New values from NIST
Special Publication 800-57 with the upper limit specified by

- Update of the underlying OpenSSH to 6.4p1
- Update to 6.4p1
Features since 6.2p2:
* ssh-agent(1) support in 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.
* ssh(1) ability to query what cryptographic algorithms are
supported in the binary.
* ssh(1): ProxyCommand=- for cases where stdin and stdout
already point to the proxy.
* ssh(1): allow IdentityFile=none
* ssh(1)/sshd(8): -E option to append debugging logs to a
specified file instead of stderr or syslog.
* sftp(1): support resuming partial downloads with the "reget"
command and on the sftp commandline or on the "get"
commandline with the "-a" (append) option.
* ssh(1): "IgnoreUnknown" configuration option to selectively
suppress errors arising from unknown configuration directives.
* sshd(8): support for submethods to be appended to required
authentication methods listed via AuthenticationMethods.

OBS-URL: https://build.opensuse.org/request/show/185789
OBS-URL: https://build.opensuse.org/package/show/network/openssh?expand=0&rev=51
Features:
* sshd(8): This release turns on pre-auth sandboxing sshd by default for
new installs, by setting UsePrivilegeSeparation=sandbox in sshd_config.
* ssh-keygen(1): Add options to specify starting line number and number of
lines to process when screening moduli candidates, allowing processing
of different parts of a candidate moduli file in parallel
* sshd(8): The Match directive now supports matching on the local (listen)
address and port upon which the incoming connection was received via
LocalAddress and LocalPort clauses.
* sshd(8): Extend sshd_config Match directive to allow setting AcceptEnv
and {Allow,Deny}{Users,Groups}
* Add support for RFC6594 SSHFP DNS records for ECDSA key types. bz#1978
* ssh-keygen(1): Allow conversion of RSA1 keys to public PEM and PKCS8
* sshd(8): Allow the sshd_config PermitOpen directive to accept "none" as
an argument to refuse all port-forwarding requests.
* sshd(8): Support "none" as an argument for AuthorizedPrincipalsFile
* ssh-keyscan(1): Look for ECDSA keys by default. bz#1971
* sshd(8): Add "VersionAddendum" to sshd_config to allow server operators
to append some arbitrary text to the server SSH protocol banner.
Bugfixes:
* ssh(1)/sshd(8): Don't spin in accept() in situations of file
descriptor exhaustion. Instead back off for a while.
* ssh(1)/sshd(8): Remove hmac-sha2-256-96 and hmac-sha2-512-96 MACs as
they were removed from the specification. bz#2023,
* sshd(8): Handle long comments in config files better. bz#2025
* ssh(1): Delay setting tty_flag so RequestTTY options are correctly
picked up. bz#1995
* sshd(8): Fix handling of /etc/nologin incorrectly being applied to root
on platforms that use login_cap.
