1openssh (1:7.3p1-1) UNRELEASED; urgency=medium
2
3 * New upstream release (http://www.openssh.com/txt/release-7.3):
4 - SECURITY: sshd(8): Mitigate a potential denial-of-service attack
5 against the system's crypt(3) function via sshd(8). An attacker could
6 send very long passwords that would cause excessive CPU use in
7 crypt(3). sshd(8) now refuses to accept password authentication
8 requests of length greater than 1024 characters.
9 - SECURITY: ssh(1), sshd(8): Fix observable timing weakness in the CBC
10 padding oracle countermeasures. Note that CBC ciphers are disabled by
11 default and only included for legacy compatibility.
12 - SECURITY: ssh(1), sshd(8): Improve operation ordering of MAC
13 verification for Encrypt-then-MAC (EtM) mode transport MAC algorithms
14 to verify the MAC before decrypting any ciphertext. This removes the
15 possibility of timing differences leaking facts about the plaintext,
16 though no such leakage has been observed.
17 - ssh(1): Add a ProxyJump option and corresponding -J command-line flag
18 to allow simplified indirection through a one or more SSH bastions or
19 "jump hosts".
20 - ssh(1): Add an IdentityAgent option to allow specifying specific agent
21 sockets instead of accepting one from the environment.
22 - ssh(1): Allow ExitOnForwardFailure and ClearAllForwardings to be
23 optionally overridden when using ssh -W.
24 - ssh(1), sshd(8): Implement support for the IUTF8 terminal mode as per
25 draft-sgtatham-secsh-iutf8-00 (closes: #337041, LP: #394570).
26 - ssh(1), sshd(8): Add support for additional fixed Diffie-Hellman 2K,
27 4K and 8K groups from draft-ietf-curdle-ssh-kex-sha2-03.
28 - ssh-keygen(1), ssh(1), sshd(8): Support SHA256 and SHA512 RSA
29 signatures in certificates.
30 - ssh(1): Add an Include directive for ssh_config(5) files (closes:
31 #536031).
32 - ssh(1): Permit UTF-8 characters in pre-authentication banners sent
33 from the server.
34 - ssh(1), sshd(8): Reduce the syslog level of some relatively common
35 protocol events from LOG_CRIT.
36 - sshd(8): Refuse AuthenticationMethods="" in configurations and accept
37 AuthenticationMethods=any for the default behaviour of not requiring
38 multiple authentication.
39 - sshd(8): Remove obsolete and misleading "POSSIBLE BREAK-IN ATTEMPT!"
40 message when forward and reverse DNS don't match.
41 - ssh(1): Deduplicate LocalForward and RemoteForward entries to fix
42 failures when both ExitOnForwardFailure and hostname canonicalisation
43 are enabled.
44 - sshd(8): Remove fallback from moduli to obsolete "primes" file that
45 was deprecated in 2001 (LP: #1528251).
46 - sshd_config(5): Correct description of UseDNS: it affects ssh hostname
47 processing for authorized_keys, not known_hosts.
48 - sshd(8): Send ClientAliveInterval pings when a time-based RekeyLimit
49 is set; previously keepalive packets were not being sent.
50 - sshd(8): Whitelist more architectures to enable the seccomp-bpf
51 sandbox.
52 - scp(1): Respect the local user's LC_CTYPE locale (closes: #396295).
53 - Take character display widths into account for the progressmeter
54 (closes: #407088).
