2007-12-24* New upstream release (closes: #453367).Colin Watson
- 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). * Update to current GSSAPI patch from http://www.sxw.org.uk/computing/patches/openssh-4.6p1-gsskex-20070312.patch; install ChangeLog.gssapi.

entropy.c needs seteuid(getuid()) for the setuid(original_uid) to succeed. Patch by gert@greenie.muc.de. This fixes one part of Bug 208

2002-01-22 - (djm) autoconf hacking:Damien Miller
- We don't support --without-zlib currently, so don't allow it. - Rework cryptographic random number support detection. We now detect whether OpenSSL seeds itself. If it does, then we don't bother with the ssh-rand-helper program. You can force the use of ssh-rand-helper using the --with-rand-helper configure argument - Simplify and clean up ssh-rand-helper configuration
2001-12-24 - (djm) Ignore fix & patchlevel in OpenSSL version check. Patch fromDamien Miller
solar@openwall.com - (djm) Rework entropy code. If the OpenSSL PRNG is has not been internally seeded, execute a subprogram "ssh-rand-helper" to obtain some entropy for us. Rewrite the old in-process entropy collecter as an example ssh-rand-helper. - (djm) Always perform ssh_prng_cmds path lookups in configure, even if we don't end up using ssh_prng_cmds (so we always get a valid file)
2001-08-06 - (djm) Fix interrupted read in entropy gatherer. Spotted by markus@ onDamien Miller
a fast UltraSPARC.
2001-06-27 - (djm) Fix a few warnings the above turned upDamien Miller
2001-03-19 - (djm) Seed PRNG at startup, rather than waiting for arc4random calls toDamien Miller
do it implicitly.
2001-03-04 - Allow PRNGd entropy collection from localhost TCP socket. ReplaceDamien Miller
"--with-egd-pool" configure option with "--with-prngd-socket" and "--with-prngd-port" options. Debugged and improved by Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>
