Changelog
openssh (1:7.2p1-1) unstable; urgency=medium
* New upstream release (http://www.openssh.com/txt/release-7.2):
- This release disables a number of legacy cryptographic algorithms by
default in ssh:
+ Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and
the rijndael-cbc aliases for AES.
+ MD5-based and truncated HMAC algorithms.
These algorithms are already disabled by default in sshd.
- ssh(1), sshd(8): Remove unfinished and unused roaming code (was
already forcibly disabled in OpenSSH 7.1p2).
- ssh(1): Eliminate fallback from untrusted X11 forwarding to trusted
forwarding when the X server disables the SECURITY extension.
- ssh(1), sshd(8): Increase the minimum modulus size supported for
diffie-hellman-group-exchange to 2048 bits.
- sshd(8): Pre-auth sandboxing is now enabled by default (previous
releases enabled it for new installations via sshd_config).
- all: Add support for RSA signatures using SHA-256/512 hash algorithms
based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt.
- ssh(1): Add an AddKeysToAgent client option which can be set to 'yes',
'no', 'ask', or 'confirm', and defaults to 'no'. When enabled, a
private key that is used during authentication will be added to
ssh-agent if it is running (with confirmation enabled if set to
'confirm').
- sshd(8): Add a new authorized_keys option "restrict" that includes all
current and future key restrictions (no-*-forwarding, etc.). Also add
permissive versions of the existing restrictions, e.g. "no-pty" ->
"pty". This simplifies the task of setting up restricted keys and
ensures they are maximally-restricted, regardless of any permissions
we might implement in the future.
- ssh(1): Add ssh_config CertificateFile option to explicitly list
certificates.
- ssh-keygen(1): Allow ssh-keygen to change the key comment for all
supported formats (closes: #811125).
- ssh-keygen(1): Allow fingerprinting from standard input, e.g.
"ssh-keygen -lf -" (closes: #509058).
- ssh-keygen(1): Allow fingerprinting multiple public keys in a file,
e.g. "ssh-keygen -lf ~/.ssh/authorized_keys".
- sshd(8): Support "none" as an argument for sshd_config Foreground and
ChrootDirectory. Useful inside Match blocks to override a global
default.
- ssh-keygen(1): Support multiple certificates (one per line) and
reading from standard input (using "-f -") for "ssh-keygen -L"
- ssh-keyscan(1): Add "ssh-keyscan -c ..." flag to allow fetching
certificates instead of plain keys.
- ssh(1): Better handle anchored FQDNs (e.g. 'cvs.openbsd.org.') in
hostname canonicalisation - treat them as already canonical and remove
the trailing '.' before matching ssh_config.
- sftp(1): Existing destination directories should not terminate
recursive uploads (regression in OpenSSH 6.8; LP: #1553378).
* Use HTTPS for Vcs-* URLs, and link to cgit rather than gitweb.
* Restore slogin symlinks for compatibility, although they were removed
upstream.
