- 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.

OBS-URL: https://build.opensuse.org/request/show/354941
OBS-URL: https://build.opensuse.org/package/show/network/openssh?expand=0&rev=95
- Update of the underlying OpenSSH to 6.6p1
- Remove uneeded dependency on the OpenLDAP server (openldap2)
from openssh-helpers. openssh-helpers just depends on the
openldap client libraries, which will be auto-generated by rpm.
- 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
