# enable trusted X11 forwarding by default in both sshd and sshsystem-wide
# configuration

Accepting request 230097 from home:pcerny:factory - 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 OBS-URL: https://build.opensuse.org/request/show/230097 OBS-URL: https://build.opensuse.org/package/show/network/openssh?expand=0&rev=76

Accepting request 222365 from home:pcerny:factory - 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 OBS-URL: https://build.opensuse.org/request/show/222365 OBS-URL: https://build.opensuse.org/package/show/network/openssh?expand=0&rev=63
