Changes since OpenSSH 9.4
=========================
This release fixes a number of bugs and adds some small features.
Potentially incompatible changes
--------------------------------
* ssh-keygen(1): generate Ed25519 keys by default. Ed25519 public keys
are very convenient due to their small size. Ed25519 keys are
specified in RFC 8709 and OpenSSH has supported them since version 6.5
(January 2014).
* sshd(8): the Subsystem directive now accurately preserves quoting of
subsystem commands and arguments. This may change behaviour for exotic
configurations, but the most common subsystem configuration
(sftp-server) is unlikely to be affected.
New features
------------
* ssh(1): add keystroke timing obfuscation to the client. This attempts
to hide inter-keystroke timings by sending interactive traffic at
fixed intervals (default: every 20ms) when there is only a small
amount of data being sent. It also sends fake "chaff" keystrokes for
a random interval after the last real keystroke. These are
controlled by a new ssh_config ObscureKeystrokeTiming keyword.
* ssh(1), sshd(8): Introduce a transport-level ping facility. This adds
a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
implement a ping capability. These messages use numbers in the "local
extensions" number space and are advertised using a "ping@openssh.com"
ext-info message with a string version number of "0".
* sshd(8): allow override of Subsystem directives in sshd Match blocks.
Bugfixes
--------
* scp(1): fix scp in SFTP mode recursive upload and download of
directories that contain symlinks to other directories. In scp mode,
the links would be followed, but in SFTP mode they were not. bz3611
* ssh-keygen(1): handle cr+lf (instead of just cr) line endings in
sshsig signature files.
* ssh(1): interactive mode for ControlPersist sessions if they
originally requested a tty.
* sshd(8): make PerSourceMaxStartups first-match-wins
* sshd(8): limit artificial login delay to a reasonable maximum (5s)
and don't delay at all for the "none" authentication mechanism.cw
bz3602
* sshd(8): Log errors in kex_exchange_identification() with level
verbose instead of error to reduce preauth log spam. All of those
get logged with a more generic error message by sshpkt_fatal().
* sshd(8): correct math for ClientAliveInterval that caused the probes
to be sent less frequently than configured.
* ssh(1): fix regression in OpenSSH 9.4 (mux.c r1.99) that caused
multiplexed sessions to ignore SIGINT under some circumstances.
Changes since OpenSSH 9.3p2
===========================
This release fixes a number of bugs and adds some small features.
Potentially incompatible changes
--------------------------------
* This release removes support for older versions of libcrypto.
OpenSSH now requires LibreSSL >= 3.1.0 or OpenSSL >= 1.1.1.
Note that these versions are already deprecated by their upstream
vendors.
* ssh-agent(1): PKCS#11 modules must now be specified by their full
paths. Previously dlopen(3) could search for them in system
library directories.
New features
------------
* ssh(1): allow forwarding Unix Domain sockets via ssh -W.
* ssh(1): add support for configuration tags to ssh(1).
This adds a ssh_config(5) "Tag" directive and corresponding
"Match tag" predicate that may be used to select blocks of
configuration similar to the pf.conf(5) keywords of the same
name.
* ssh(1): add a "match localnetwork" predicate. This allows matching
on the addresses of available network interfaces and may be used to
vary the effective client configuration based on network location.
* ssh(1), sshd(8), ssh-keygen(1): infrastructure support for KRL
extensions. This defines wire formats for optional KRL extensions
and implements parsing of the new submessages. No actual extensions
are supported at this point.
* sshd(8): AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
accept two additional %-expansion sequences: %D which expands to
the routing domain of the connected session and %C which expands
to the addresses and port numbers for the source and destination
of the connection.
* ssh-keygen(1): increase the default work factor (rounds) for the
bcrypt KDF used to derive symmetric encryption keys for passphrase
protected key files by 50%.
Bugfixes
--------
* ssh-agent(1): improve isolation between loaded PKCS#11 modules
by running separate ssh-pkcs11-helpers for each loaded provider.
* ssh(1): make -f (fork after authentication) work correctly with
multiplexed connections, including ControlPersist. bz3589 bz3589
* ssh(1): make ConnectTimeout apply to multiplexing sockets and not
just to network connections.
* ssh-agent(1), ssh(1): improve defences against invalid PKCS#11
modules being loaded by checking that the requested module
contains the required symbol before loading it.
* sshd(8): fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
appears before it in sshd_config. Since OpenSSH 8.7 the
AuthorizedPrincipalsCommand directive was incorrectly ignored in
this situation. bz3574
* sshd(8), ssh(1), ssh-keygen(1): remove vestigal support for KRL
signatures When the KRL format was originally defined, it included
support for signing of KRL objects. However, the code to sign KRLs
and verify KRL signatues was never completed in OpenSSH. This
release removes the partially-implemented code to verify KRLs.
All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
KRL files.
* All: fix a number of memory leaks and unreachable/harmless integer
overflows.
* ssh-agent(1), ssh(1): don't truncate strings logged from PKCS#11
modules; GHPR406
* sshd(8), ssh(1): better validate CASignatureAlgorithms in
ssh_config and sshd_config. Previously this directive would accept
certificate algorithm names, but these were unusable in practice as
OpenSSH does not support CA chains. bz3577
* ssh(1): make `ssh -Q CASignatureAlgorithms` only list signature
algorithms that are valid for CA signing. Previous behaviour was
to list all signing algorithms, including certificate algorithms.
* ssh-keyscan(1): gracefully handle systems where rlimits or the
maximum number of open files is larger than INT_MAX; bz3581
* ssh-keygen(1): fix "no comment" not showing on when running
`ssh-keygen -l` on multiple keys where one has a comment and other
following keys do not. bz3580
* scp(1), sftp(1): adjust ftruncate() logic to handle servers that
reorder requests. Previously, if the server reordered requests then
the resultant file would be erroneously truncated.
* ssh(1): don't incorrectly disable hostname canonicalization when
CanonicalizeHostname=yes and ProxyJump was expicitly set to
"none". bz3567
* scp(1): when copying local->remote, check that the source file
exists before opening an SFTP connection to the server. Based on
GHPR#370
security/openssh: New fido option. This enables built-in U2F/FIDO security key support, without any SSH_SK_PROVIDER middleware library needed. Works only on platforms with working libfido2, so not enabled by default yet. We should enable it by default in NetBSD>=10 and maybe some other platforms.
security: align variable assignments pkglint -Wall -F --only aligned --only indent -r No manual corrections.
Add legacymodsz option to allow short (insecure) RSA keys This may be required in order to access old, non-upgradable, devices for which modulus size is less than 1024 bits (frequently 768 bits).
openssh: Add optional command line editing to "sftp" Add new package option "editline" (enabled by default) which adds command line editing and filename completion to the "sftp" client. Bump the package revision because of this change.
Include 'pam' in the suggested/default list of options on NetBSD. Add LICENSE setting, near as I can tell "modified-bsd". Bump PKGREVISION.

Log Message:
Update openssh to 7.4.1 (7.4p1), including security fixes.
For full changes, please refer ChangeLog file.
Future deprecation notice
=========================
We plan on retiring more legacy cryptography in future releases,
specifically:
* In approximately August 2017, removing remaining support for the
SSH v.1 protocol (client-only and currently compile-time disabled).
* In the same release, removing support for Blowfish and RC4 ciphers
and the RIPE-MD160 HMAC. (These are currently run-time disabled).
* Refusing all RSA keys smaller than 1024 bits (the current minimum
is 768 bits)
* The next release of OpenSSH will remove support for running sshd(8)
with privilege separation disabled.
* The next release of portable OpenSSH will remove support for
OpenSSL version prior to 1.0.1.
This list reflects our current intentions, but please check the final
release notes for future releases.
Potentially-incompatible changes
================================
This release includes a number of changes that may affect existing
configurations:
* This release removes server support for the SSH v.1 protocol.
* ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit
block ciphers are not safe in 2016 and we don't want to wait until
attacks like SWEET32 are extended to SSH. As 3des-cbc was the
only mandatory cipher in the SSH RFCs, this may cause problems
connecting to older devices using the default configuration,
but it's highly likely that such devices already need explicit
configuration for key exchange and hostkey algorithms already
anyway.
* sshd(8): Remove support for pre-authentication compression.
Doing compression early in the protocol probably seemed reasonable
in the 1990s, but today it's clearly a bad idea in terms of both
cryptography (cf. multiple compression oracle attacks in TLS) and
attack surface. Pre-auth compression support has been disabled by
default for >10 years. Support remains in the client.
* ssh-agent will refuse to load PKCS#11 modules outside a whitelist
of trusted paths by default. The path whitelist may be specified
at run-time.
* sshd(8): When a forced-command appears in both a certificate and
an authorized keys/principals command= restriction, sshd will now
refuse to accept the certificate unless they are identical.
The previous (documented) behaviour of having the certificate
forced-command override the other could be a bit confusing and
error-prone.
* sshd(8): Remove the UseLogin configuration directive and support
for having /bin/login manage login sessions.
Changes since OpenSSH 7.3
=========================
This is primarily a bugfix release.
Security
--------
* ssh-agent(1): Will now refuse to load PKCS#11 modules from paths
outside a trusted whitelist (run-time configurable). Requests to
load modules could be passed via agent forwarding and an attacker
could attempt to load a hostile PKCS#11 module across the forwarded
agent channel: PKCS#11 modules are shared libraries, so this would
result in code execution on the system running the ssh-agent if the
attacker has control of the forwarded agent-socket (on the host
running the sshd server) and the ability to write to the filesystem
of the host running ssh-agent (usually the host running the ssh
client). Reported by Jann Horn of Project Zero.
* sshd(8): When privilege separation is disabled, forwarded Unix-
domain sockets would be created by sshd(8) with the privileges of
'root' instead of the authenticated user. This release refuses
Unix-domain socket forwarding when privilege separation is disabled
(Privilege separation has been enabled by default for 14 years).
Reported by Jann Horn of Project Zero.
* sshd(8): Avoid theoretical leak of host private key material to
privilege-separated child processes via realloc() when reading
keys. No such leak was observed in practice for normal-sized keys,
nor does a leak to the child processes directly expose key material
to unprivileged users. Reported by Jann Horn of Project Zero.
* sshd(8): The shared memory manager used by pre-authentication
compression support had a bounds checks that could be elided by
some optimising compilers. Additionally, this memory manager was
incorrectly accessible when pre-authentication compression was
disabled. This could potentially allow attacks against the
privileged monitor process from the sandboxed privilege-separation
process (a compromise of the latter would be required first).
This release removes support for pre-authentication compression
from sshd(8). Reported by Guido Vranken using the Stack unstable
optimisation identification tool (http://css.csail.mit.edu/stack/)
* sshd(8): Fix denial-of-service condition where an attacker who
sends multiple KEXINIT messages may consume up to 128MB per
connection. Reported by Shi Lei of Gear Team, Qihoo 360.
* sshd(8): Validate address ranges for AllowUser and DenyUsers
directives at configuration load time and refuse to accept invalid
ones. It was previously possible to specify invalid CIDR address
ranges (e.g. user@127.1.2.3/55) and these would always match,
possibly resulting in granting access where it was not intended.

Update openssh to 6.9.1 (OpenSSH 6.9p1) which contains security fix.
pkgsrc change:
* tcp_wrappers support was removed from release 6.7, but add it refering
FreeBSD's ports.
* hpn-patch is also based on FreeBSD's ports.
Security
--------
* ssh(1): when forwarding X11 connections with ForwardX11Trusted=no,
connections made after ForwardX11Timeout expired could be permitted
and no longer subject to XSECURITY restrictions because of an
ineffective timeout check in ssh(1) coupled with "fail open"
behaviour in the X11 server when clients attempted connections with
expired credentials. This problem was reported by Jann Horn.
* ssh-agent(1): fix weakness of agent locking (ssh-add -x) to
password guessing by implementing an increasing failure delay,
storing a salted hash of the password rather than the password
itself and using a timing-safe comparison function for verifying
unlock attempts. This problem was reported by Ryan Castellucci.

Full details of the vulnerability are available at: http://www.openssh.com/txt/gcmrekey.adv Changes since OpenSSH 6.2 is too many to write here, please refer the release note: http://www.openssh.com/txt/release-6.3.
Changes since OpenSSH 6.1
=========================
This release introduces a number of new features:
Features:
* ssh(1)/sshd(8): Added support for AES-GCM authenticated encryption in
SSH protocol 2. The new cipher is available as aes128-gcm@openssh.com
and aes256-gcm@openssh.com. It uses an identical packet format to the
AES-GCM mode specified in RFC 5647, but uses simpler and different
selection rules during key exchange.
* ssh(1)/sshd(8): Added support for encrypt-then-mac (EtM) MAC modes
for SSH protocol 2. These modes alter the packet format and compute
the MAC over the packet length and encrypted packet rather than over
the plaintext data. These modes are considered more secure and are
used by default when available.
* ssh(1)/sshd(8): Added support for the UMAC-128 MAC as
"umac-128@openssh.com" and "umac-128-etm@openssh.com". The latter
being an encrypt-then-mac mode.
* sshd(8): Added support for multiple required authentication in SSH
protocol 2 via an AuthenticationMethods option. This option lists
one or more comma-separated lists of authentication method names.
Successful completion of all the methods in any list is required for
authentication to complete. This allows, for example, requiring a
user having to authenticate via public key or GSSAPI before they
are offered password authentication.
* sshd(8)/ssh-keygen(1): Added support for Key Revocation Lists
(KRLs), a compact binary format to represent lists of revoked keys
and certificates that take as little as one bit per certificate when
revoking by serial number. KRLs may be generated using ssh-keygen(1)
and are loaded into sshd(8) via the existing RevokedKeys sshd_config
option.
* ssh(1): IdentitiesOnly now applies to keys obtained from a
PKCS11Provider. This allows control of which keys are offered from
tokens using IdentityFile.
* sshd(8): sshd_config(5)'s AllowTcpForwarding now accepts "local"
and "remote" in addition to its previous "yes"/"no" keywords to allow
the server to specify whether just local or remote TCP forwarding is
enabled.
* sshd(8): Added a sshd_config(5) option AuthorizedKeysCommand to
support fetching authorized_keys from a command in addition to (or
instead of) from the filesystem. The command is run under an account
specified by an AuthorizedKeysCommandUser sshd_config(5) option.
* sftp-server(8): Now supports a -d option to allow the starting
directory to be something other than the user's home directory.
* ssh-keygen(1): Now allows fingerprinting of keys hosted in PKCS#11
tokens using "ssh-keygen -lD pkcs11_provider".
* ssh(1): When SSH protocol 2 only is selected (the default), ssh(1)
now immediately sends its SSH protocol banner to the server without
waiting to receive the server's banner, saving time when connecting.
* ssh(1): Added ~v and ~V escape sequences to raise and lower the
logging level respectively.
* ssh(1): Made the escape command help (~?) context sensitive so that
only commands that will work in the current session are shown.
* ssh-keygen(1): When deleting host lines from known_hosts using
"ssh-keygen -R host", ssh-keygen(1) now prints details of which lines
were removed.
Bugfixes:
* ssh(1): Force a clean shutdown of ControlMaster client sessions when
the ~. escape sequence is used. This means that ~. should now work in
mux clients even if the server is no longer responding.
* ssh(1): Correctly detect errors during local TCP forward setup in
multiplexed clients. bz#2055
* ssh-add(1): Made deleting explicit keys "ssh-add -d" symmetric with
adding keys with respect to certificates. It now tries to delete the
corresponding certificate and respects the -k option to allow deleting
of the key only.
* sftp(1): Fix a number of parsing and command-editing bugs, including
bz#1956
* ssh(1): When muxmaster is run with -N, ensured that it shuts down
gracefully when a client sends it "-O stop" rather than hanging around.
bz#1985
* ssh-keygen(1): When screening moduli candidates, append to the file
rather than overwriting to allow resumption. bz#1957
* ssh(1): Record "Received disconnect" messages at ERROR rather than
INFO priority. bz#2057.
* ssh(1): Loudly warn if explicitly-provided private key is unreadable.
bz#1981
Portable OpenSSH:
* sshd(8): The Linux seccomp-filter sandbox is now supported on ARM
platforms where the kernel supports it.
* sshd(8): The seccomp-filter sandbox will not be enabled if the system
headers support it at compile time, regardless of whether it can be
enabled then. If the run-time system does not support seccomp-filter,
sshd will fall back to the rlimit pseudo-sandbox.
* ssh(1): Don't link in the Kerberos libraries. They aren't necessary
on the client, just on sshd(8). bz#2072
* Fix GSSAPI linking on Solaris, which uses a differently-named GSSAPI
library. bz#2073
* Fix compilation on systems with openssl-1.0.0-fips.
* Fix a number of errors in the RPM spec files.
Changes since OpenSSH 6.0
=========================
This is primarily a bugfix release.
Features:
* sshd(8): This release turns on pre-auth sandboxing sshd by default for
new installs, by setting UsePrivilegeSeparation=sandbox in sshd_config.
* ssh-keygen(1): Add options to specify starting line number and number of
lines to process when screening moduli candidates, allowing processing
of different parts of a candidate moduli file in parallel
* sshd(8): The Match directive now supports matching on the local (listen)
address and port upon which the incoming connection was received via
LocalAddress and LocalPort clauses.
* sshd(8): Extend sshd_config Match directive to allow setting AcceptEnv
and {Allow,Deny}{Users,Groups}
* Add support for RFC6594 SSHFP DNS records for ECDSA key types. bz#1978
* ssh-keygen(1): Allow conversion of RSA1 keys to public PEM and PKCS8
* sshd(8): Allow the sshd_config PermitOpen directive to accept "none" as
an argument to refuse all port-forwarding requests.
* sshd(8): Support "none" as an argument for AuthorizedPrincipalsFile
* ssh-keyscan(1): Look for ECDSA keys by default. bz#1971
* sshd(8): Add "VersionAddendum" to sshd_config to allow server operators
to append some arbitrary text to the server SSH protocol banner.
Bugfixes:
* ssh(1)/sshd(8): Don't spin in accept() in situations of file
descriptor exhaustion. Instead back off for a while.
* ssh(1)/sshd(8): Remove hmac-sha2-256-96 and hmac-sha2-512-96 MACs as
they were removed from the specification. bz#2023,
* sshd(8): Handle long comments in config files better. bz#2025
* ssh(1): Delay setting tty_flag so RequestTTY options are correctly
picked up. bz#1995
* sshd(8): Fix handling of /etc/nologin incorrectly being applied to root
on platforms that use login_cap.
Portable OpenSSH:
* sshd(8): Allow sshd pre-auth sandboxing to fall-back to the rlimit
sandbox from the Linux SECCOMP filter sandbox when the latter is
not available in the kernel.
* ssh(1): Fix NULL dereference when built with LDNS and using DNSSEC to
retrieve a CNAME SSHFP record.
* Fix cross-compilation problems related to pkg-config. bz#1996
Changes since OpenSSH 5.9
=========================
This is primarily a bugfix release.
Features:
* ssh-keygen(1): Add optional checkpoints for moduli screening
* ssh-add(1): new -k option to load plain keys (skipping certificates)
* sshd(8): Add wildcard support to PermitOpen, allowing things like
"PermitOpen localhost:*". bz #1857
* ssh(1): support for cancelling local and remote port forwards via the
multiplex socket. Use ssh -O cancel -L xx:xx:xx -R yy:yy:yy user@host"
to request the cancellation of the specified forwardings
* support cancellation of local/dynamic forwardings from ~C commandline
Bugfixes:
* ssh(1): ensure that $DISPLAY contains only valid characters before
using it to extract xauth data so that it can't be used to play local
shell metacharacter games.
* ssh(1): unbreak remote portforwarding with dynamic allocated listen ports
* scp(1): uppress adding '--' to remote commandlines when the first
argument does not start with '-'. saves breakage on some
difficult-to-upgrade embedded/router platforms
* ssh(1)/sshd(8): fix typo in IPQoS parsing: there is no "AF14" class,
but there is an "AF21" class
* ssh(1)/sshd(8): do not permit SSH2_MSG_SERVICE_REQUEST/ACCEPT during
rekeying
* ssh(1): skip attempting to create ~/.ssh when -F is passed
* sshd(8): unbreak stdio forwarding when ControlPersist is in use; bz#1943
* sshd(1): send tty break to pty master instead of (probably already
closed) slave side; bz#1859
* sftp(1): silence error spam for "ls */foo" in directory with files;
bz#1683
* Fixed a number of memory and file descriptor leaks
Portable OpenSSH:
* Add a new privilege separation sandbox implementation for Linux's
new seccomp sandbox, automatically enabled on platforms that support
it. (Note: privilege separation sandboxing is still experimental)
* Fix compilation problems on FreeBSD, where libutil contained openpty()
but not login().
* ssh-keygen(1): don't fail in -A on platforms that don't support ECC
* Add optional support for LDNS, a BSD licensed DNS resolver library
which supports DNSSEC
* Relax OpenSSL version check to allow running OpenSSH binaries on
systems with OpenSSL libraries with a newer "fix" or "patch" level
than the binaries were originally compiled on (previous check only
allowed movement within "patch" releases). bz#1991
* Fix builds using contributed Redhat spec file. bz#1992
Changes since OpenSSH 5.8
=========================
Features:
* Introduce sandboxing of the pre-auth privsep child using an optional
sshd_config(5) "UsePrivilegeSeparation=sandbox" mode that enables
mandatory restrictions on the syscalls the privsep child can perform.
This intention is to prevent a compromised privsep child from being
used to attack other hosts (by opening sockets and proxying) or
probing local kernel attack surface.
Three concrete sandbox implementation are provided (selected at
configure time): systrace, seatbelt and rlimit.
The systrace sandbox uses systrace(4) in unsupervised "fast-path"
mode, where a list of permitted syscalls is supplied. Any syscall not
on the list results in SIGKILL being sent to the privsep child. Note
that this requires a kernel with the new SYSTR_POLICY_KILL option
(only OpenBSD has this mode at present).
The seatbelt sandbox uses OS X/Darwin sandbox(7) facilities with a
strict (kSBXProfilePureComputation) policy that disables access to
filesystem and network resources.
The rlimit sandbox is a fallback choice for platforms that don't
support a better one; it uses setrlimit() to reset the hard-limit
of file descriptors and processes to zero, which should prevent
the privsep child from forking or opening new network connections.
Sandboxing of the privilege separated child process is currently
experimental but should become the default in a future release.
Native sandboxes for other platforms are welcome (e.g. Capsicum,
Linux pid/net namespaces, etc.)
* Add new SHA256-based HMAC transport integrity modes from
http://www.ietf.org/id/draft-dbider-sha2-mac-for-ssh-02.txt
These modes are hmac-sha2-256, hmac-sha2-256-96, hmac-sha2-512,
and hmac-sha2-512-96, and are available by default in ssh(1) and
sshd(8)
* The pre-authentication sshd(8) privilege separation slave process
now logs via a socket shared with the master process, avoiding the
need to maintain /dev/log inside the chroot.
* ssh(1) now warns when a server refuses X11 forwarding
* sshd_config(5)'s AuthorizedKeysFile now accepts multiple paths,
separated by whitespace. The undocumented AuthorizedKeysFile2
option is deprecated (though the default for AuthorizedKeysFile
includes .ssh/authorized_keys2)
* sshd_config(5): similarly deprecate UserKnownHostsFile2 and
GlobalKnownHostsFile2 by making UserKnownHostsFile and
GlobalKnownHostsFile accept multiple options and default to
include known_hosts2
* Retain key comments when loading v.2 keys. These will be visible
in "ssh-add -l" and other places. bz#439
* ssh(1) and sshd(8): set IPv6 traffic class from IPQoS (as well as
IPv4 ToS/DSCP). bz#1855
* ssh_config(5)'s ControlPath option now expands %L to the host
portion of the destination host name.
* ssh_config(5) "Host" options now support negated Host matching, e.g.
Host *.example.org !c.example.org
User mekmitasdigoat
Will match "a.example.org", "b.example.org", but not "c.example.org"
* ssh_config(5): a new RequestTTY option provides control over when a
TTY is requested for a connection, similar to the existing -t/-tt/-T
ssh(1) commandline options.
* sshd(8): allow GSSAPI authentication to detect when a server-side
failure causes authentication failure and don't count such failures
against MaxAuthTries; bz#1244
* ssh-keygen(1): Add -A option. For each of the key types (rsa1, rsa,
dsa and ecdsa) for which host keys do not exist, generate the host
keys with the default key file path, an empty passphrase, default
bits for the key type, and default comment. This is useful for
system initialisation scripts.
* ssh(1): Allow graceful shutdown of multiplexing: request that a mux
server removes its listener socket and refuse future multiplexing
requests but don't kill existing connections. This may be requested
using "ssh -O stop ..."
* ssh-add(1) now accepts keys piped from standard input. E.g.
"ssh-add - < /path/to/key"
* ssh-keysign(8) now signs hostbased authentication
challenges correctly using ECDSA keys; bz#1858
* sftp(1): document that sftp accepts square brackets to delimit
addresses (useful for IPv6); bz#1847a
* ssh(1): when using session multiplexing, the master process will
change its process title to reflect the control path in use and
when a ControlPersist-ed master is waiting to close; bz#1883 and
bz#1911
* Other minor bugs fixed: 1849 1861 1862 1869 1875 1878 1879 1892
1900 1905 1913
Portable OpenSSH Bugfixes:
* Fix a compilation error in the SELinux support code. bz#1851
* This release removes support for ssh-rand-helper. OpenSSH now
obtains its random numbers directly from OpenSSL or from
a PRNGd/EGD instance specified at configure time.
* sshd(8) now resets the SELinux process execution context before
executing passwd for password changes; bz#1891
* Since gcc >= 4.x ignores all -Wno-options options, test only the
corresponding -W-option when trying to determine whether it is
accepted; bz#1901
* Add ECDSA key generation to the Cygwin ssh-{host,user}-config
scripts.
* Updated .spec and init files for Linux; bz#1920
* Improved SELinux error messages in context change failures and
suppress error messages when attempting to change from the
"unconfined_t" type; bz#1924 bz#1919
* Fix build errors on platforms without dlopen(); bz#1929
Switch HPN patch site to the one FreeBSD uses, upstream have hidden it behind a session-based page.
Added support for OpenSSH-lpk The OpenSSH LDAP Public Key patch provides an easy way of centralizing strong user authentication by using an LDAP server for retrieving public keys instead of ~/.ssh/authorized_keys.
Re-enable PAM support, as it works fine provided one does not mix multiple 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.
PR/38394 -- disable KAFS detection for mit-krb5
Update openssh package to 5.8.1 (5.8p1). 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
Add hpn-patch for OpenSSH 5.5p1. No PKGREVISION bump since this option never worked with OpenSSH 5.5p1 before.
Updated OpenSSH to 5.3.1 (pkg/42635 by Fredrik Pettai) 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.
Update openssh package to 5.2.1(5.2p1). 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.
Update openssh package to 5.1.1 (5.1p1) 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.
Update to OpenSSH 5.0p1. Changes since 4.7: - fix two security issues - chroot support for sshd(8) - sftp server internalized in sshd(8) - assorted bug fixes
Update openssh package to 4.7.1 (4.7p1).
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)
Update openssh pacakge to 4.6.1.
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)

Log Message:
Update openssh package to 4.4.1 (openssh-4.4p1).
- A few pkglint warning clean up.
- Major changes are here. For complete changes,
see http://www.openssh.com/txt/release-4.4.
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.

Log Message:
Update to version 3.4p1
From Jason White via PR pkg/32780
Changes:
Security bugs resolved in this release:
* CVE-2006-0225: scp (as does rcp, on which it is based) invoked a
subshell to perform local to local, and remote to remote copy
operations. This subshell exposed filenames to shell expansion
twice; allowing a local attacker to create filenames containing
shell metacharacters that, if matched by a wildcard, could lead
to execution of attacker-specified commands with the privilege of
the user running scp (Bugzilla #1094)
This is primarily a bug-fix release, only one new feature has been
added:
* Add support for tunneling arbitrary network packets over a
connection between an OpenSSH client and server via tun(4) virtual
network interfaces. This allows the use of OpenSSH (4.3+) to create
a true VPN between the client and server providing real network
connectivity at layer 2 or 3. This feature is experimental and is
currently supported on OpenBSD, Linux, NetBSD (IPv4 only) and
FreeBSD. Other operating systems with tun/tap interface capability
may be added in future portable OpenSSH releases. Please refer to
the README.tun file in the source distribution for further details
and usage examples.
Some of the other bugs resolved and internal improvements are:
* Reduce default key length for new DSA keys generated by ssh-keygen
back to 1024 bits. DSA is not specified for longer lengths and does
not fully benefit from simply making keys longer. As per FIPS 186-2
Change Notice 1, ssh-keygen will refuse to generate a new DSA key
smaller or larger than 1024 bits
* Fixed X forwarding failing to start when a the X11 client is executed
in background at the time of session exit (Bugzilla #1086)
* Change ssh-keygen to generate a protocol 2 RSA key when invoked
without arguments (Bugzilla #1064)
* Fix timing variance for valid vs. invalid accounts when attempting
Kerberos authentication (Bugzilla #975)
* Ensure that ssh always returns code 255 on internal error (Bugzilla
#1137)
* Cleanup wtmp files on SIGTERM when not using privsep (Bugzilla #1029)
* Set SO_REUSEADDR on X11 listeners to avoid problems caused by
lingering sockets from previous session (X11 applications can
sometimes not connect to 127.0.0.1:60xx) (Bugzilla #1076)
* Ensure that fds 0, 1 and 2 are always attached in all programs, by
duping /dev/null to them if necessary.
* Xauth list invocation had bogus "." argument (Bugzilla #1082)
* Remove internal assumptions on key exchange hash algorithm and output
length, preparing OpenSSH for KEX methods with alternate hashes.
* Ignore junk sent by a server before it sends the "SSH-" banner
(Bugzilla #1067)
* The manpages has been significantly improves and rearranged, in
addition to other specific manpage fixes:
#1037 - Man page entries for -L and -R should mention -g.
#1077 - Descriptions for "ssh -D" and DynamicForward should mention
they can specify "bind_address" optionally.
#1088 - Incorrect descriptions in ssh_config man page for
ControlMaster=no.
#1121 - Several corrections for ssh_agent manpages
* Lots of cleanups, including fixes to memory leaks on error paths
(Bugzilla #1109, #1110, #1111 and more) and possible crashes (#1092)
* Portable OpenSSH-specific fixes:
- Pass random seed during re-exec for each connection: speeds up
processing of new connections on platforms using the OpenSSH's
builtin entropy collector (ssh-rand-helper)
- PAM fixes and improvements:
#1045 - Missing option for ignoring the /etc/nologin file
#1087 - Show PAM password expiry message from LDAP on login
#1028 - Forward final non-query conversations to client
#1126 - Prevent user from being forced to change an expired
password repeatedly on AIX in some PAM configurations.
#1045 - Do not check /etc/nologin when PAM is enabled, instead
allow PAM to handle it. Note that on platforms using
PAM, the pam_nologin module should be used in sshd's
session stack in order to maintain past behaviour
- Portability-related fixes:
#989 - Fix multiplexing regress test on Solaris
#1097 - Cross-compile fixes.
#1096 - ssh-keygen broken on HPUX.
#1098 - $MAIL being set incorrectly for HPUX server login.
#1104 - Compile error on Tru64 Unix 4.0f
#1106 - Updated .spec file and startup for SuSE.
#1122 - Use _GNU_SOURCE define in favor of __USE_GNU, fixing
compilation problems on glibc 2.4

Update openssh to 4.2p1. This is from PR #31331. Thank you, Jason. Some changes different from patches provided in that PR are: - patch-aj, patch-aq, and patch-as not changed (they appeared to be identical to previous patches) - DragonFly support also added to configure script (patch-aa) because compilation failed due to missing crypt - and install-sysconf target removed from the installation target in Makefile.in (patch-ah). Just let the pkgsrc framework install this since it now will allow it to be removed correctly on deinstall. - use "pam" instead of "PAM" as option name in the post-install target. This removes patch-ai. This also now uses openssh-4.2p1-hpn11.diff patch. I didn't test with kerberos and hpn-patch options. I did test with PAM on Linux. (The PR reported that kerberos and hpn-patch options were tested for compiling.) I tested on NetBSD 2.0.2, Linux, and DragonFly. This includes two security fixes and several bug fixes and many improvemens. The changes are listed at http://www.mindrot.org/pipermail/openssh-unix-announce/2005-September/000083.html http://www.mindrot.org/pipermail/openssh-unix-announce/2005-May/000079.html TODO: get some of these patches committed upstream.
MESSAGE file removed. As mentioned on tech-pkg in May, /etc/ssh.conf and /etc/sshd.conf is old (and I assume some configurations from there don't apply any more), user and group are not created automatically (only if PKG_CREATE_USERGROUP is at default YES), UsePrivilegeSeparation is the default, and seems to imply that openssh is insecure without it. Bump PKGREVISION. Change comment regarding MESSAGE.Interix. Removed unused MESSAGE_SUBST settings. Move one to the options.mk as it is for "pam" only.
Rename option PAM to pam (so all options are lower case). Backwards compatibility provided via PKG_OPTIONS_LEGACY_OPTS.
Create a pam.buildlink3.mk file that is used by PAM-using packages. It includes the correct buildlink3.mk file from either Linux-PAM (security/PAM) or OpenPAM (security/openpam) and eventually will support solaris-pam. pam.buildlink3.mk will: * set PAMBASE to the base directory of the PAM files; * set PAM_TYPE to the PAM implementation used. There are two variables that can be used to tweak the selection of the PAM implementation: PAM_DEFAULT is a user-settable variable whose value is the default PAM implementation to use. PAM_ACCEPTED is a package-settable list of PAM implementations that may be used by the package. Modify most packages that include PAM/buildlink3.mk to include pam.buildlink3.mk instead.
Remove support for some variables that are supposed to go away after pkgsrc-2004Q4 is branched.
Convert to use bsd.options.mk with the following options: hpn-patch kerberos PAM (only Linux) The hpn-patch option uses the patch available in: http://www.psc.edu/networking/projects/hpn-ssh/ to enable high performance connections. Also use VARBASE intead of hardcoding /var. Bump PKGREVISION.
