- CVE-2007-4752: Prevent ssh(1) from using a trusted X11 cookie if
creation of an untrusted cookie fails; found and fixed by Jan Pechanec
(closes: #444738).
- sshd(8) in new installations defaults to SSH Protocol 2 only. Existing
installations are unchanged.
- The SSH channel window size has been increased, and both ssh(1)
sshd(8) now send window updates more aggressively. These improves
performance on high-BDP (Bandwidth Delay Product) networks.
- ssh(1) and sshd(8) now preserve MAC contexts between packets, which
saves 2 hash calls per packet and results in 12-16% speedup for
arcfour256/hmac-md5.
- A new MAC algorithm has been added, UMAC-64 (RFC4418) as
"umac-64@openssh.com". UMAC-64 has been measured to be approximately
20% faster than HMAC-MD5.
- Failure to establish a ssh(1) TunnelForward is now treated as a fatal
error when the ExitOnForwardFailure option is set.
- ssh(1) returns a sensible exit status if the control master goes away
without passing the full exit status.
- When using a ProxyCommand in ssh(1), set the outgoing hostname with
gethostname(2), allowing hostbased authentication to work.
- Make scp(1) skip FIFOs rather than hanging (closes: #246774).
- Encode non-printing characters in scp(1) filenames. These could cause
copies to be aborted with a "protocol error".
- Handle SIGINT in sshd(8) privilege separation child process to ensure
that wtmp and lastlog records are correctly updated.
- Report GSSAPI mechanism in errors, for libraries that support multiple
mechanisms.
- Improve documentation for ssh-add(1)'s -d option.
- Rearrange and tidy GSSAPI code, removing server-only code being linked
into the client.
- Delay execution of ssh(1)'s LocalCommand until after all forwardings
have been established.
- In scp(1), do not truncate non-regular files.
- Improve exit message from ControlMaster clients.
- Prevent sftp-server(8) from reading until it runs out of buffer space,
whereupon it would exit with a fatal error (closes: #365541).
- pam_end() was not being called if authentication failed
(closes: #405041).
- Manual page datestamps updated (closes: #433181).

changes not previously backported to 4.3p2:
- 4.4/4.4p1 (http://www.openssh.org/txt/release-4.4):
+ On portable OpenSSH, fix a GSSAPI authentication abort that could be
used to determine the validity of usernames on some platforms.
+ Implemented conditional configuration in sshd_config(5) using the
"Match" directive. This allows some configuration options to be
selectively overridden if specific criteria (based on user, group,
hostname and/or address) are met. So far a useful subset of
post-authentication options are supported and more are expected to
be added in future releases.
+ Add support for Diffie-Hellman group exchange key agreement with a
final hash of SHA256.
+ Added a "ForceCommand" directive to sshd_config(5). Similar to the
command="..." option accepted in ~/.ssh/authorized_keys, this forces
the execution of the specified command regardless of what the user
requested. This is very useful in conjunction with the new "Match"
option.
+ Add a "PermitOpen" directive to sshd_config(5). This mirrors the
permitopen="..." authorized_keys option, allowing fine-grained
control over the port-forwardings that a user is allowed to
establish.
+ Add optional logging of transactions to sftp-server(8).
+ ssh(1) will now record port numbers for hosts stored in
~/.ssh/known_hosts when a non-standard port has been requested
(closes: #50612).
+ Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a
non-zero exit code) when requested port forwardings could not be
established.
+ Extend sshd_config(5) "SubSystem" declarations to allow the
specification of command-line arguments.
+ Replacement of all integer overflow susceptible invocations of
malloc(3) and realloc(3) with overflow-checking equivalents.
+ Many manpage fixes and improvements.
+ Add optional support for OpenSSL hardware accelerators (engines),
enabled using the --with-ssl-engine configure option.
+ Tokens in configuration files may be double-quoted in order to
contain spaces (closes: #319639).
+ Move a debug() call out of a SIGCHLD handler, fixing a hang when the
session exits very quickly (closes: #307890).
+ Fix some incorrect buffer allocation calculations (closes: #410599).
+ ssh-add doesn't ask for a passphrase if key file permissions are too
liberal (closes: #103677).
+ Likewise, ssh doesn't ask either (closes: #99675).
- 4.6/4.6p1 (http://www.openssh.org/txt/release-4.6):
+ sshd now allows the enabling and disabling of authentication methods
on a per user, group, host and network basis via the Match directive
in sshd_config.
+ Fixed an inconsistent check for a terminal when displaying scp
progress meter (closes: #257524).
+ Fix "hang on exit" when background processes are running at the time
of exit on a ttyful/login session (closes: #88337).

library interfaces aren't very helpful. Fix up the DOPR_OUTCH macro
so it works properly and modify its callers so that they don't pre or
post decrement arguments that are conditionally evaluated. While there,
put SNPRINTF_CONST back as it prevents build failures in some
configurations. ok djm@ (for most of it)

loginsuccess on AIX immediately after authentication to clear the failed
login count. Previously this would only happen when an interactive
session starts (ie when a pty is allocated) but this means that accounts
that have primarily non-interactive sessions (eg scp's) may gradually
accumulate enough failures to lock out an account. This change may have
a side effect of creating two audit records, one with a tty of "ssh"
corresponding to the authentication and one with the allocated pty per
interactive session.
