versions of libcrypto in sshd. This can happen if OpenSSH is linked with
pkgsrc's OpenSSL and if using nss_ldap, which pulls base-system OpenSSL
through kerberos libraries. One needs to disable the krb5 of nss_ldap
in order to fix that.

Cygwin-specific service installer script ssh-host-config. The actual
functionality is the same, the revisited version is just more
exact when it comes to check for problems which disallow to run
certain aspects of the script. So, part of this script and the also
rearranged service helper script library "csih" is to check if all
the tools required to run the script are available on the system.
The new script also is more thorough to inform the user why the
script failed. Patch from vinschen at redhat com.

For changes from 5.5 to 5.7, please refer http://openssh.com/txt/release-5.7
and http://openssh.com/txt/release-5.6 in detail.
Changes since OpenSSH 5.7
=========================
Security:
* Fix vulnerability in legacy certificate signing introduced in
OpenSSH-5.6 and found by Mateusz Kocielski.
Legacy certificates signed by OpenSSH 5.6 or 5.7 included data from
the stack in place of a random nonce field. The contents of the stack
do not appear to contain private data at this point, but this cannot
be stated with certainty for all platform, library and compiler
combinations. In particular, there exists a risk that some bytes from
the privileged CA key may be accidentally included.
A full advisory for this issue is available at:
http://www.openssh.com/txt/legacy-cert.adv
Portable OpenSSH Bugfixes:
* Fix compilation failure when enableing SELinux support.
* Do not attempt to call SELinux functions when SELinux is disabled.
bz#1851
|
|
* header file location of libbind is differ than SFU.
* treat all Interxi as same, not only interix3.
|
|
No PKGREVISION bump since this option never worked
with OpenSSH 5.5p1 before.
|
|
Lots of changes, including
* After a transition period of about 10 years, this release disables
SSH protocol 1 by default. Clients and servers that need to use the
legacy protocol must explicitly enable it in ssh_config / sshd_config
or on the command-line.
* Remove the libsectok/OpenSC-based smartcard code and add support for
PKCS#11 tokens. This support is automatically enabled on all
platforms that support dlopen(3) and was inspired by patches written
by Alon Bar-Lev. Details in the ssh(1) and ssh-add(1) manpages.
* Add support for certificate authentication of users and hosts using a
new, minimal OpenSSH certificate format (not X.509). Certificates
contain a public key, identity information and some validity
constraints and are signed with a standard SSH public key using
ssh-keygen(1). CA keys may be marked as trusted in authorized_keys
or via a TrustedUserCAKeys option in sshd_config(5) (for user
authentication), or in known_hosts (for host authentication).
Documentation for certificate support may be found in ssh-keygen(1),
sshd(8) and ssh(1) and a description of the protocol extensions in
PROTOCOL.certkeys.
* Added a 'netcat mode' to ssh(1): "ssh -W host:port ..." This connects
stdio on the client to a single port forward on the server. This
allows, for example, using ssh as a ProxyCommand to route connections
via intermediate servers. bz#1618

This is a bugfix release, no new features have been added.
Changes since OpenSSH 5.2
=========================
General Bugfixes:
* Do not limit home directory paths to 256 characters. bz#1615
* Several minor documentation and correctness fixes.
Portable OpenSSH Bugfixes:
* This release removes for support for very old versions of Cygwin and
for Windows 95/98/ME
* Move the deletion of PAM credentials on logout to after the session
close. bz#1534
* Make PrintLastLog work on AIX. bz#1595
* Avoid compile errors on FreeBSD from conflicts in glob.h. bz#1634
* Delay dropping of root privileges on AIX so chroot and pam_open_session
work correctly. bz#1249 and bz#1567
* Increase client IO buffer on Cygwin to 64K, realising a significant
performance improvement.
* Roll back bz#1241 (better handling for expired passwords on Tru64).
The change broke password logins on some configurations.
* Accept ENOSYS as a fallback error when attempting atomic
rename(). bz#1535
* Fix passing of variables to recursive make(1) invocations on Solaris.
bz#1505
* Skip the tcgetattr call on the pty master on Solaris, since it never
succeeds and can hang if large amounts of data is sent to the slave
(eg a copy-paste). bz#1528
* Fix detection of krb5-config. bz#1639
* Fix test for server-assigned remote forwarding port for non-root users.
bz#1578
* Fix detection of libresolv on OSX 10.6.

Changes since OpenSSH 5.1
=========================
Security:
* This release changes the default cipher order to prefer the AES CTR
modes and the revised "arcfour256" mode to CBC mode ciphers that are
susceptible to CPNI-957037 "Plaintext Recovery Attack Against SSH".
* This release also adds countermeasures to mitigate CPNI-957037-style
attacks against the SSH protocol's use of CBC-mode ciphers. Upon
detection of an invalid packet length or Message Authentication
Code, ssh/sshd will continue reading up to the maximum supported
packet length rather than immediately terminating the connection.
This eliminates most of the known differences in behaviour that
leaked information about the plaintext of injected data which formed
the basis of this attack. We believe that these attacks are rendered
infeasible by these changes.
New features:
* Added a -y option to ssh(1) to force logging to syslog rather than
stderr, which is useful when running daemonised (ssh -f)
* The sshd_config(5) ForceCommand directive now accepts commandline
arguments for the internal-sftp server.
* The ssh(1) ~C escape commandline now support runtime creation of
dynamic (-D) port forwards.
* Support the SOCKS4A protocol in ssh(1) dynamic (-D) forwards.
(bz#1482)
* Support remote port forwarding with a listen port of '0'. This
informs the server that it should dynamically allocate a listen
port and report it back to the client. (bz#1003)
* sshd(8) now supports setting PermitEmptyPasswords and
AllowAgentForwarding in Match blocks
Bug and documentation fixes
* Repair a ssh(1) crash introduced in openssh-5.1 when the client is
sent a zero-length banner (bz#1496)
* Due to interoperability problems with certain
broken SSH implementations, the eow@openssh.com and
no-more-sessions@openssh.com protocol extensions are now only sent
to peers that identify themselves as OpenSSH.
* Make ssh(1) send the correct channel number for
SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to
avoid triggering 'Non-public channel' error messages on sshd(8) in
openssh-5.1.
* Avoid printing 'Non-public channel' warnings in sshd(8), since the
ssh(1) has sent incorrect channel numbers since ~2004 (this reverts
a behaviour introduced in openssh-5.1).
* Avoid double-free in ssh(1) ~C escape -L handler (bz#1539)
* Correct fail-on-error behaviour in sftp(1) batchmode for remote
stat operations. (bz#1541)
* Disable nonfunctional ssh(1) ~C escape handler in multiplex slave
connections. (bz#1543)
* Avoid hang in ssh(1) when attempting to connect to a server that
has MaxSessions=0 set.
* Multiple fixes to sshd(8) configuration test (-T) mode
* Several core and portable OpenSSH bugs fixed: 1380, 1412, 1418,
1419, 1421, 1490, 1491, 1492, 1514, 1515, 1518, 1520, 1538, 1540
* Many manual page improvements.

Changes from OpenSSH 5.0 is huge to write here, please refer its
release note: http://www.openssh.com/txt/release-5.1.
I quote only Security section from the release note.
Security:
* sshd(8): Avoid X11 man-in-the-middle attack on HP/UX (and possibly
other platforms) when X11UseLocalhost=no
When attempting to bind(2) to a port that has previously been bound
with SO_REUSEADDR set, most operating systems check that either the
effective user-id matches the previous bind (common on BSD-derived
systems) or that the bind addresses do not overlap (Linux and
Solaris).
Some operating systems, such as HP/UX, do not perform these checks
and are vulnerable to an X11 man-in-the-middle attack when the
sshd_config(5) option X11UseLocalhost has been set to "no" - an
attacker may establish a more-specific bind, which will be used in
preference to sshd's wildcard listener.
Modern BSD operating systems, Linux, OS X and Solaris implement the
above checks and are not vulnerable to this attack, nor are systems
where the X11UseLocalhost has been left at the default value of
"yes".
Portable OpenSSH 5.1 avoids this problem for all operating systems
by not setting SO_REUSEADDR when X11UseLocalhost is set to no.
This vulnerability was reported by sway2004009 AT hotmail.com.

and to support the "inet6" option instead.
Remaining usage of USE_INET6 was solely for the benefit of the scripts
that generate the README.html files. Replace:
BUILD_DEFS+= USE_INET6
with
BUILD_DEFS+= IPV6_READY
and teach the README-generation tools to look for that instead.
This nukes USE_INET6 from pkgsrc proper. We leave a tiny bit of code
to continue to support USE_INET6 for pkgsrc-wip until it has been nuked
from there as well.
|
|
Changes since OpenSSH 4.6:
============================
Security bugs resolved in this release:
* Prevent ssh(1) from using a trusted X11 cookie if creation of an
untrusted cookie fails; found and fixed by Jan Pechanec.
Other changes, new functionality and fixes in this release:
* 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.
* A -K flag was added to ssh(1) to set GSSAPIAuthentication=Yes
* 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. (bz #1261)
* The following bugs have been fixed in this release:
- When using a ProxyCommand in ssh(1), set the outgoing hostname with
gethostname(2), allowing hostbased authentication to work (bz #616)
- Make scp(1) skip FIFOs rather than hanging (bz #856)
- Encode non-printing characters in scp(1) filenames.
these could cause copies to be aborted with a "protocol error"
(bz #891)
- Handle SIGINT in sshd(8) privilege separation child process to
ensure that wtmp and lastlog records are correctly updated
(bz #1196)
- Report GSSAPI mechanism in errors, for libraries that support
multiple mechanisms (bz #1220)
- Improve documentation for ssh-add(1)'s -d option (bz #1224)
- Rearrange and tidy GSSAPI code, removing server-only code being
linked into the client. (bz #1225)
- Delay execution of ssh(1)'s LocalCommand until after all forwadings
have been established. (bz #1232)
- In scp(1), do not truncate non-regular files (bz #1236)
- Improve exit message from ControlMaster clients. (bz #1262)
- Prevent sftp-server(8) from reading until it runs out of buffer
space, whereupon it would exit with a fatal error. (bz #1286)
* Portable OpenSSH bugs fixed:
- Fix multiple inclusion of paths.h on AIX 5.1 systems. (bz #1243)
- Implement getpeereid for Solaris using getpeerucred. Solaris
systems will now refuse ssh-agent(1) and ssh(1) ControlMaster
clients from different, non-root users (bz #1287)
- Fix compilation warnings by including string.h if found. (bz #1294)
- Remove redefinition of _res in getrrsetbyname.c for platforms that
already define it. (bz #1299)
- Fix spurious "chan_read_failed for istate 3" errors from sshd(8),
a side-effect of the "hang on exit" fix introduced in 4.6p1.
(bz #1306)
- pam_end() was not being called if authentication failed (bz #1322)
- Fix SELinux support when SELinux is in permissive mode. Previously
sshd(8) was treating SELinux errors as always fatal. (bz #1325)
- Ensure that pam_setcred(..., PAM_ESTABLISH_CRED) is called before
pam_setcred(..., PAM_REINITIALIZE_CRED), fixing pam_dhkeys.
(bz #1339)
- Fix privilege separation on QNX - pre-auth only, this platform does
not support file descriptior passing needed for post-auth privilege
separation. (bz #1343)

Fix nasty "error: channel 0: chan_read_failed for istate 3" message.

the owner of all installed files is a non-root user. This change
affects most packages that require special users or groups by making
them use the specified unprivileged user and group instead.
(1) Add two new variables PKG_GROUPS_VARS and PKG_USERS_VARS to
unprivileged.mk. These two variables are lists of other bmake
variables that define package-specific users and groups. Packages
that have user-settable variables for users and groups, e.g. apache
and APACHE_{USER,GROUP}, courier-mta and COURIER_{USER,GROUP},
etc., should list these variables in PKG_USERS_VARS and PKG_GROUPS_VARS
so that unprivileged.mk can know to set them to ${UNPRIVILEGED_USER}
and ${UNPRIVILEGED_GROUP}.
(2) Modify packages to use PKG_GROUPS_VARS and PKG_USERS_VARS.

Changes since OpenSSH 4.5:
============================
* 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.
* The following bugs have been fixed in this release:
- Clear SIGALRM when restarting due to SIGHUP. Prevents stray
signal from taking down sshd if a connection was pending at
the time SIGHUP was received
- sftp returned a zero exit status when upload failed due to write
errors (bugzilla #1252)
- fixed an inconsistent check for a terminal when displaying scp
progress meter (bugzilla #1265)
- Parsing of time values in Match blocks was incorrectly applied
to the global configuration (bugzilla #1275)
- Allow multiple forwarding options to work when specified in a
PermitOpen directive (bugzilla #1267)
- Interoperate with ssh.com versions that do not support binding
remote port forwarding sessions to a hostname (bugzilla #1019)
* Portable OpenSSH bugs fixed:
- "hang on exit" when background processes are running at the time
of exit on a ttyful/login session (bugzilla #52)
- Fix typos in the ssh-rand-helper(8) man page (bugzilla #1259)
- Check that some SIG records have been returned in getrrsetbyname
(bugzilla #1281)
- Fix contrib/findssl for platforms that lack "which" (bugzilla
#1237)
- Work around bug in OpenSSL 0.9.8e that broke aes256-ctr,
aes192-ctr, arcfour256 (bugzilla #1291)

This fixes the issue that, when "options edns0" is turned on (usually in
/etc/resolv.conf), ssh doesn't see it, and thus fails to request a DNSSEC
response, which in turn leads to SSHFP records being considered insecure.

Changes since OpenSSH 4.3:
============================
Security bugs resolved in this release:
* Fix a pre-authentication denial of service found by Tavis Ormandy,
that would cause sshd(8) to spin until the login grace time
expired.
* Fix an unsafe signal hander reported by Mark Dowd. The signal
handler was vulnerable to a race condition that could be exploited
to perform a pre-authentication denial of service. On portable
OpenSSH, this vulnerability could theoretically lead to
pre-authentication remote code execution if GSSAPI authentication
is enabled, but the likelihood of successful exploitation appears
remote.
* On portable OpenSSH, fix a GSSAPI authentication abort that could
be used to determine the validity of usernames on some platforms.
This release includes the following new functionality and fixes:
* 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/authorized_keys when a non-standard port has been requested.
* 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
* New portable OpenSSH-specific features:
- Add optional support for SELinux, controlled using the
--with-selinux configure option (experimental)
- Add optional support for Solaris process contracts, enabled
using the --with-solaris-contracts configure option (experimental)
This option will also include SMF metadata in Solaris packages
built using the "make package" target
- Add optional support for OpenSSL hardware accelerators (engines),
enabled using the --with-ssl-engine configure option.
