* New upstream release (closes: #453367).
- 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).
