Merge changes between OpenSSH-9.1 and OpenSSH-9.3
Import OpenSSH 9.3 + the fix from p2 for the PKCS#11 remote provider The previous version was OpenSSH 9.1 OpenSSH 9.3p2 (2023-07-19) OpenSSH 9.3p2 was released on 2023-07-19. It is available from the mirrors listed at https://www.openssh.com/. OpenSSH is a 100% complete SSH protocol 2.0 implementation and includes sftp client and server support. Once again, we would like to thank the OpenSSH community for their continued support of the project, especially those who contributed code or patches, reported bugs, tested snapshots or donated to the project. More information on donations may be found at: https://www.openssh.com/donations.html Changes since OpenSSH 9.3 ========================= This release fixes a security bug. Security ======== Fix CVE-2023-38408 - a condition where specific libaries loaded via ssh-agent(1)'s PKCS#11 support could be abused to achieve remote code execution via a forwarded agent socket if the following conditions are met: * Exploitation requires the presence of specific libraries on the victim system. * Remote exploitation requires that the agent was forwarded to an attacker-controlled system. Exploitation can also be prevented by starting ssh-agent(1) with an empty PKCS#11/FIDO allowlist (ssh-agent -P '') or by configuring an allowlist that contains only specific provider libraries. This vulnerability was discovered and demonstrated to be exploitable by the Qualys Security Advisory team. In addition to removing the main precondition for exploitation, this release removes the ability for remote ssh-agent(1) clients to load PKCS#11 modules by default (see below). Potentially-incompatible changes -------------------------------- * ssh-agent(8): the agent will now refuse requests to load PKCS#11 modules issued by remote clients by default. A flag has been added to restore the previous behaviour "-Oallow-remote-pkcs11". Note that ssh-agent(8) depends on the SSH client to identify requests that are remote. The OpenSSH >=8.9 ssh(1) client does this, but forwarding access to an agent socket using other tools may circumvent this restriction.

It is available from the mirrors listed at https://www.openssh.com/. OpenSSH is a 100% complete SSH protocol 2.0 implementation and includes sftp client and server support. Once again, we would like to thank the OpenSSH community for their continued support of the project, especially those who contributed code or patches, reported bugs, tested snapshots or donated to the project. More information on donations may be found at: https://www.openssh.com/donations.html Changes since OpenSSH 9.2 ========================= This release fixes a number of security bugs. Security ======== This release contains fixes for a security problem and a memory safety problem. The memory safety problem is not believed to be exploitable, but we report most network-reachable memory faults as security bugs. * ssh-add(1): when adding smartcard keys to ssh-agent(1) with the per-hop destination constraints (ssh-add -h ...) added in OpenSSH 8.9, a logic error prevented the constraints from being communicated to the agent. This resulted in the keys being added without constraints. The common cases of non-smartcard keys and keys without destination constraints are unaffected. This problem was reported by Luci Stanescu. * ssh(1): Portable OpenSSH provides an implementation of the getrrsetbyname(3) function if the standard library does not provide it, for use by the VerifyHostKeyDNS feature. A specifically crafted DNS response could cause this function to perform an out-of-bounds read of adjacent stack data, but this condition does not appear to be exploitable beyond denial-of- service to the ssh(1) client. The getrrsetbyname(3) replacement is only included if the system's standard library lacks this function and portable OpenSSH was not compiled with the ldns library (--with-ldns). getrrsetbyname(3) is only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This problem was found by the Coverity static analyzer. New features ------------ * ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when outputting SSHFP fingerprints to allow algorithm selection. bz3493 * sshd(8): add a `sshd -G` option that parses and prints the effective configuration without attempting to load private keys and perform other checks. This allows usage of the option before keys have been generated and for configuration evaluation and verification by unprivileged users. Bugfixes -------- * scp(1), sftp(1): fix progressmeter corruption on wide displays; bz3534 * ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability of private keys as some systems are starting to disable RSA/SHA1 in libcrypto. * sftp-server(8): fix a memory leak. GHPR363 * ssh(1), sshd(8), ssh-keyscan(1): remove vestigal protocol compatibility code and simplify what's left. * Fix a number of low-impact Coverity static analysis findings. These include several reported via bz2687 * ssh_config(5), sshd_config(5): mention that some options are not first-match-wins. * Rework logging for the regression tests. Regression tests will now capture separate logs for each ssh and sshd invocation in a test. * ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage says it should; bz3532. * ssh(1): ensure that there is a terminating newline when adding a new entry to known_hosts; bz3529 Portability ----------- * sshd(8): harden Linux seccomp sandbox. Move to an allowlist of mmap(2), madvise(2) and futex(2) flags, removing some concerning kernel attack surface. * sshd(8): improve Linux seccomp-bpf sandbox for older systems; bz3537 Checksums: ========== - SHA1 (openssh-9.3.tar.gz) = 5f9d2f73ddfe94f3f0a78bdf46704b6ad7b66ec7 - SHA256 (openssh-9.3.tar.gz) = eRcXkFZByz70DUBUcyIdvU0pVxP2X280FrmV8pyUdrk= - SHA1 (openssh-9.3p1.tar.gz) = 610959871bf8d6baafc3525811948f85b5dd84ab - SHA256 (openssh-9.3p1.tar.gz) = 6bq6dwGnalHz2Fpiw4OjydzZf6kAuFm8fbEUwYaK+Kg= Please note that the SHA256 signatures are base64 encoded and not hexadecimal (which is the default for most checksum tools). The PGP key used to sign the releases is available from the mirror sites: https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/RELEASE_KEY.asc Reporting Bugs: =============== - Please read https://www.openssh.com/report.html Security bugs should be reported directly to openssh@openssh.com OpenSSH 9.2/9.2p1 (2023-02-02) OpenSSH 9.2 was released on 2023-02-02. It is available from the mirrors listed at https://www.openssh.com/. OpenSSH is a 100% complete SSH protocol 2.0 implementation and includes sftp client and server support. Once again, we would like to thank the OpenSSH community for their continued support of the project, especially those who contributed code or patches, reported bugs, tested snapshots or donated to the project. More information on donations may be found at: https://www.openssh.com/donations.html Changes since OpenSSH 9.1 ========================= This release fixes a number of security bugs. Security ======== This release contains fixes for two security problems and a memory safety problem. The memory safety problem is not believed to be exploitable, but we report most network-reachable memory faults as security bugs. * sshd(8): fix a pre-authentication double-free memory fault introduced in OpenSSH 9.1. This is not believed to be exploitable, and it occurs in the unprivileged pre-auth process that is subject to chroot(2) and is further sandboxed on most major platforms. * ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option would ignore its first argument unless it was one of the special keywords "any" or "none", causing the permission list to fail open if only one permission was specified. bz3515 * ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs options were enabled, and the system/libc resolver did not check that names in DNS responses were valid, then use of these options could allow an attacker with control of DNS to include invalid characters (possibly including wildcards) in names added to known_hosts files when they were updated. These names would still have to match the CanonicalizePermittedCNAMEs allow-list, so practical exploitation appears unlikely. Potentially-incompatible changes -------------------------------- * ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that controls whether the client-side ~C escape sequence that provides a command-line is available. Among other things, the ~C command-line could be used to add additional port-forwards at runtime. This option defaults to "no", disabling the ~C command-line that was previously enabled by default. Turning off the command-line allows platforms that support sandboxing of the ssh(1) client (currently only OpenBSD) to use a stricter default sandbox policy. New features ------------ * sshd(8): add support for channel inactivity timeouts via a new sshd_config(5) ChannelTimeout directive. This allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. * sshd(8): add a sshd_config UnusedConnectionTimeout option to terminate client connections that have no open channels for a length of time. This complements the ChannelTimeout option above. * sshd(8): add a -V (version) option to sshd like the ssh client has. * ssh(1): add a "Host" line to the output of ssh -G showing the original hostname argument. bz3343 * scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to allow control over some SFTP protocol parameters: the copy buffer length and the number of in-flight requests, both of which are used during upload/download. Previously these could be controlled in sftp(1) only. This makes them available in both SFTP protocol clients using the same option character sequence. * ssh-keyscan(1): allow scanning of complete CIDR address ranges, e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then it will be expanded to all possible addresses in the range including the all-0s and all-1s addresses. bz#976 * ssh(1): support dynamic remote port forwarding in escape command-line's -R processing. bz#3499 Bugfixes -------- * ssh(1): when restoring non-blocking mode to stdio fds, restore exactly the flags that ssh started with and don't just clobber them with zero, as this could also remove the append flag from the set. bz3523 * ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none and a hostkey in one of the system known hosts file changes. * scp(1): switch scp from using pipes to a socket-pair for communication with its ssh sub-processes, matching how sftp(1) operates. * sshd(8): clear signal mask early in main(); sshd may have been started with one or more signals masked (sigprocmask(2) is not cleared on fork/exec) and this could interfere with various things, e.g. the login grace timer. Execution environments that fail to clear the signal mask before running sshd are clearly broken, but apparently they do exist. * ssh(1): warn if no host keys for hostbased auth can be loaded. * sshd(8): Add server debugging for hostbased auth that is queued and sent to the client after successful authentication, but also logged to assist in diagnosis of HostbasedAuthentication problems. bz3507 * ssh(1): document use of the IdentityFile option as being usable to list public keys as well as private keys. GHPR352 * sshd(8): check for and disallow MaxStartups values less than or equal to zero during config parsing, rather than failing later at runtime. bz3489 * ssh-keygen(1): fix parsing of hex cert expiry times specified on the command-line when acting as a CA. * scp(1): when scp(1) is using the SFTP protocol for transport (the default), better match scp/rcp's handling of globs that don't match the globbed characters but do match literally (e.g. trying to transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode would not match these pathnames but legacy scp/rcp mode would. bz3488 * ssh-agent(1): document the "-O no-restrict-websafe" command-line option. * ssh(1): honour user's umask(2) if it is more restrictive then the ssh default (022). Portability ----------- * sshd(8): allow writev(2) in the Linux seccomp sandbox. This seems to be used by recent glibcs at least in some configurations during error conditions. bz3512. * sshd(8): simply handling of SSH_CONNECTION PAM env var, removing global variable and checking the return value from pam_putenv. bz3508 * sshd(8): disable SANDBOX_SECCOMP_FILTER_DEBUG that was mistakenly enabled during the OpenSSH 9.1 release cycle. * misc: update autotools and regenerate the config files using the latest autotools * all: use -fzero-call-used-regs=used on clang 15 instead of -fzero-call-used-reg=all, as some versions of clang 15 have miscompile code when it was enabled. bz3475 * sshd(8): defer PRNG seeding until after the initial closefrom(2) call. PRNG seeding will initialize OpenSSL, and some engine providers (e.g. Intel's QAT) will open descriptors for their own use that closefrom(2) could clobber. bz3483 * misc: in the poll(2)/ppoll(2) compatibility code, avoid assuming the layout of fd_set. * sftp-server(8), ssh-agent(1): fix ptrace(2) disabling on older FreeBSD kernels. Some versions do not support using id 0 to refer to the current PID for procctl, so try again with getpid() explicitly before failing. * configure.ac: fix -Wstrict-prototypes in configure test code. Clang 16 now warns on this and legacy prototypes will be removed in C23. GHPR355 * configure.ac: fix setres*id checks to work with clang-16. glibc has the prototypes for setresuid behind _GNU_SOURCE, and clang 16 will error out on implicit function definitions. bz3497 Checksums: ========== - SHA1 (openssh-9.2.tar.gz) = e4b806b7c81b87d6c90afe97b3d016ba6cf3ba1c - SHA256 (openssh-9.2.tar.gz) = yYe9uaaWSeetXGXOxuaaEiIsLnvITmGW+l5dgMZb9QU= - SHA1 (openssh-9.2p1.tar.gz) = 3b172b8e971773a7018bbf3231f6589ae539ca4b - SHA256 (openssh-9.2p1.tar.gz) = P2bb8WVftF9Q4cVtpiqwEhjCKIB7ITONY068351xz0Y= Please note that the SHA256 signatures are base64 encoded and not hexadecimal (which is the default for most checksum tools).

merge conflicts between 9.0 and 9.1
Import OpenSSH-9.1 (previously we were on OpenSSH-9.0) This release is focused on bug fixing. Security ======== This release contains fixes for three minor memory safety problems. None are believed to be exploitable, but we report most memory safety problems as potential security vulnerabilities out of caution. * ssh-keyscan(1): fix a one-byte overflow in SSH- banner processing. Reported by Qualys * ssh-keygen(1): double free() in error path of file hashing step in signing/verify code; GHPR333 * ssh-keysign(8): double-free in error path introduced in openssh-8.9 Potentially-incompatible changes -------------------------------- * The portable OpenSSH project now signs commits and release tags using git's recent SSH signature support. The list of developer signing keys is included in the repository as .git_allowed_signers and is cross-signed using the PGP key that is still used to sign release artifacts: https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/RELEASE_KEY.asc * ssh(1), sshd(8): SetEnv directives in ssh_config and sshd_config are now first-match-wins to match other directives. Previously if an environment variable was multiply specified the last set value would have been used. bz3438 * ssh-keygen(8): ssh-keygen -A (generate all default host key types) will no longer generate DSA keys, as these are insecure and have not been used by default for some years. New features ------------ * ssh(1), sshd(8): add a RequiredRSASize directive to set a minimum RSA key length. Keys below this length will be ignored for user authentication and for host authentication in sshd(8). ssh(1) will terminate a connection if the server offers an RSA key that falls below this limit, as the SSH protocol does not include the ability to retry a failed key exchange. * sftp-server(8): add a "users-groups-by-id@openssh.com" extension request that allows the client to obtain user/group names that correspond to a set of uids/gids. * sftp(1): use "users-groups-by-id@openssh.com" sftp-server extension (when available) to fill in user/group names for directory listings. * sftp-server(8): support the "home-directory" extension request defined in draft-ietf-secsh-filexfer-extensions-00. This overlaps a bit with the existing "expand-path@openssh.com", but some other clients support it. * ssh-keygen(1), sshd(8): allow certificate validity intervals, sshsig verification times and authorized_keys expiry-time options to accept dates in the UTC time zone in addition to the default of interpreting them in the system time zone. YYYYMMDD and YYMMDDHHMM[SS] dates/times will be interpreted as UTC if suffixed with a 'Z' character. Also allow certificate validity intervals to be specified in raw seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890. This is intended for use by regress tests and other tools that call ssh-keygen as part of a CA workflow. bz3468 * sftp(1): allow arguments to the sftp -D option, e.g. sftp -D "/usr/libexec/sftp-server -el debug3" * ssh-keygen(1): allow the existing -U (use agent) flag to work with "-Y sign" operations, where it will be interpreted to require that the private keys is hosted in an agent; bz3429 Bugfixes -------- * ssh-keygen(1): implement the "verify-required" certificate option. This was already documented when support for user-verified FIDO keys was added, but the ssh-keygen(1) code was missing. * ssh-agent(1): hook up the restrict_websafe command-line flag; previously the flag was accepted but never actually used. * sftp(1): improve filename tab completions: never try to complete names to non-existent commands, and better match the completion type (local or remote filename) against the argument position being completed. * ssh-keygen(1), ssh(1), ssh-agent(1): several fixes to FIDO key handling, especially relating to keys that request user-verification. These should reduce the number of unnecessary PIN prompts for keys that support intrinsic user verification. GHPR302, GHPR329 * ssh-keygen(1): when enrolling a FIDO resident key, check if a credential with matching application and user ID strings already exists and, if so, prompt the user for confirmation before overwriting the credential. GHPR329 * sshd(8): improve logging of errors when opening authorized_keys files. bz2042 * ssh(1): avoid multiplexing operations that could cause SIGPIPE from causing the client to exit early. bz3454 * ssh_config(5), sshd_config(5): clarify that the RekeyLimit directive applies to both transmitted and received data. GHPR328 * ssh-keygen(1): avoid double fclose() in error path. * sshd(8): log an error if pipe() fails while accepting a connection. bz3447 * ssh(1), ssh-keygen(1): fix possible NULL deref when built without FIDO support. bz3443 * ssh-keyscan(1): add missing *-sk types to ssh-keyscan manpage. GHPR294. * sshd(8): ensure that authentication passwords are cleared from memory in error paths. GHPR286 * ssh(1), ssh-agent(1): avoid possibility of notifier code executing kill(-1). GHPR286 * ssh_config(5): note that the ProxyJump directive also accepts the same tokens as ProxyCommand. GHPR305. * scp(1): do not not ftruncate(3) files early when in sftp mode. The previous behaviour of unconditionally truncating the destination file would cause "scp ~/foo localhost:foo" and the reverse "scp localhost:foo ~/foo" to delete all the contents of their destination. bz3431 * ssh-keygen(1): improve error message when 'ssh-keygen -Y sign' is unable to load a private key; bz3429 * sftp(1), scp(1): when performing operations that glob(3) a remote path, ensure that the implicit working directory used to construct that path escapes glob(3) characters. This prevents glob characters from being processed in places they shouldn't, e.g. "cd /tmp/a*/", "get *.txt" should have the get operation treat the path "/tmp/a*" literally and not attempt to expand it. * ssh(1), sshd(8): be stricter in which characters will be accepted in specifying a mask length; allow only 0-9. GHPR278 * ssh-keygen(1): avoid printing hash algorithm twice when dumping a KRL * ssh(1), sshd(8): continue running local I/O for open channels during SSH transport rekeying. This should make ~-escapes work in the client (e.g. to exit) if the connection happened to have stalled during a rekey event. * ssh(1), sshd(8): avoid potential poll() spin during rekeying * Further hardening for sshbuf internals: disallow "reparenting" a hierarchical sshbuf and zero the entire buffer if reallocation fails. GHPR287 Portability ----------- * ssh(1), ssh-keygen(1), sshd(8): automatically enable the built-in FIDO security key support if libfido2 is found and usable, unless --without-security-key-builtin was requested. * ssh(1), ssh-keygen(1), sshd(8): many fixes to make the WinHello FIDO device usable on Cygwin. The windows://hello FIDO device will be automatically used by default on this platform unless requested otherwise, or when probing resident FIDO credentials (an operation not currently supported by WinHello). * Portable OpenSSH: remove workarounds for obsolete and unsupported versions of OpenSSL libcrypto. In particular, this release removes fallback support for OpenSSL that lacks AES-CTR or AES-GCM. Those AES cipher modes were added to OpenSSL prior to the minimum version currently supported by OpenSSH, so this is not expected to impact any currently supported configurations. * sshd(8): fix SANDBOX_SECCOMP_FILTER_DEBUG on current Linux/glibc * All: resync and clean up internal CSPRNG code. * scp(1), sftp(1), sftp-server(8): avoid linking these programs with unnecessary libraries. They are no longer linked against libz and libcrypto. This may be of benefit to space constrained systems using any of those components in isolation. * sshd(8): add AUDIT_ARCH_PPC to supported seccomp sandbox architectures. * configure: remove special casing of crypt(). configure will no longer search for crypt() in libcrypto, as it was removed from there years ago. configure will now only search libc and libcrypt. * configure: refuse to use OpenSSL 3.0.4 due to potential RCE in its RSA implementation (CVE-2022-2274) on x86_64. * All: request 1.1x API compatibility for OpenSSL >=3.x; GHPR322 * ssh(1), ssh-keygen(1), sshd(8): fix a number of missing includes required by the XMSS code on some platforms. * sshd(8): cache timezone data in capsicum sandbox.
merge local changes between openssh 8.4 and 8.5
OpenSSH 8.5/8.5p1 (2021-03-03) OpenSSH 8.5 was released on 2021-03-03. It is available from the mirrors listed at https://www.openssh.com/. OpenSSH is a 100% complete SSH protocol 2.0 implementation and includes sftp client and server support. Once again, we would like to thank the OpenSSH community for their continued support of the project, especially those who contributed code or patches, reported bugs, tested snapshots or donated to the project. More information on donations may be found at: https://www.openssh.com/donations.html Future deprecation notice ========================= It is now possible[1] to perform chosen-prefix attacks against the SHA-1 algorithm for less than USD$50K. In the SSH protocol, the "ssh-rsa" signature scheme uses the SHA-1 hash algorithm in conjunction with the RSA public key algorithm. OpenSSH will disable this signature scheme by default in the near future. Note that the deactivation of "ssh-rsa" signatures does not necessarily require cessation of use for RSA keys. In the SSH protocol, keys may be capable of signing using multiple algorithms. In particular, "ssh-rsa" keys are capable of signing using "rsa-sha2-256" (RSA/SHA256), "rsa-sha2-512" (RSA/SHA512) and "ssh-rsa" (RSA/SHA1). Only the last of these is being turned off by default. This algorithm is unfortunately still used widely despite the existence of better alternatives, being the only remaining public key signature algorithm specified by the original SSH RFCs that is still enabled by default. The better alternatives include: * The RFC8332 RSA SHA-2 signature algorithms rsa-sha2-256/512. These algorithms have the advantage of using the same key type as "ssh-rsa" but use the safe SHA-2 hash algorithms. These have been supported since OpenSSH 7.2 and are already used by default if the client and server support them. * The RFC8709 ssh-ed25519 signature algorithm. It has been supported in OpenSSH since release 6.5. * The RFC5656 ECDSA algorithms: ecdsa-sha2-nistp256/384/521. These have been supported by OpenSSH since release 5.7. To check whether a server is using the weak ssh-rsa public key algorithm, for host authentication, try to connect to it after removing the ssh-rsa algorithm from ssh(1)'s allowed list: ssh -oHostKeyAlgorithms=-ssh-rsa user@host If the host key verification fails and no other supported host key types are available, the server software on that host should be upgraded. This release enables the UpdateHostKeys option by default to assist the client by automatically migrating to better algorithms. [1] "SHA-1 is a Shambles: First Chosen-Prefix Collision on SHA-1 and Application to the PGP Web of Trust" Leurent, G and Peyrin, T (2020) https://eprint.iacr.org/2020/014.pdf Security ======== * ssh-agent(1): fixed a double-free memory corruption that was introduced in OpenSSH 8.2 . We treat all such memory faults as potentially exploitable. This bug could be reached by an attacker with access to the agent socket. On modern operating systems where the OS can provide information about the user identity connected to a socket, OpenSSH ssh-agent and sshd limit agent socket access only to the originating user and root. Additional mitigation may be afforded by the system's malloc(3)/free(3) implementation, if it detects double-free conditions. The most likely scenario for exploitation is a user forwarding an agent either to an account shared with a malicious user or to a host with an attacker holding root access. * Portable sshd(8): Prevent excessively long username going to PAM. This is a mitigation for a buffer overflow in Solaris' PAM username handling (CVE-2020-14871), and is only enabled for Sun-derived PAM implementations. This is not a problem in sshd itself, it only prevents sshd from being used as a vector to attack Solaris' PAM. It does not prevent the bug in PAM from being exploited via some other PAM application. GHPR212 Potentially-incompatible changes ================================ This release includes a number of changes that may affect existing configurations: * ssh(1), sshd(8): this release changes the first-preference signature algorithm from ECDSA to ED25519. * ssh(1), sshd(8): set the TOS/DSCP specified in the configuration for interactive use prior to TCP connect. The connection phase of the SSH session is time-sensitive and often explicitly interactive. The ultimate interactive/bulk TOS/DSCP will be set after authentication completes. * ssh(1), sshd(8): remove the pre-standardization cipher rijndael-cbc@lysator.liu.se. It is an alias for aes256-cbc before it was standardized in RFC4253 (2006), has been deprecated and disabled by default since OpenSSH 7.2 (2016) and was only briefly documented in ssh.1 in 2001. * ssh(1), sshd(8): update/replace the experimental post-quantum hybrid key exchange method based on Streamlined NTRU Prime coupled with X25519. The previous sntrup4591761x25519-sha512@tinyssh.org method is replaced with sntrup761x25519-sha512@openssh.com. Per its designers, the sntrup4591761 algorithm was superseded almost two years ago by sntrup761. (note this both the updated method and the one that it replaced are disabled by default) * ssh(1): disable CheckHostIP by default. It provides insignificant benefits while making key rotation significantly more difficult, especially for hosts behind IP-based load-balancers. Changes since OpenSSH 8.4 ========================= New features ------------ * ssh(1): this release enables UpdateHostkeys by default subject to some conservative preconditions: - The key was matched in the UserKnownHostsFile (and not in the GlobalKnownHostsFile). - The same key does not exist under another name. - A certificate host key is not in use. - known_hosts contains no matching wildcard hostname pattern. - VerifyHostKeyDNS is not enabled. - The default UserKnownHostsFile is in use. We expect some of these conditions will be modified or relaxed in future. * ssh(1), sshd(8): add a new LogVerbose configuration directive for that allows forcing maximum debug logging by file/function/line pattern-lists. * ssh(1): when prompting the user to accept a new hostkey, display any other host names/addresses already associated with the key. * ssh(1): allow UserKnownHostsFile=none to indicate that no known_hosts file should be used to identify host keys. * ssh(1): add a ssh_config KnownHostsCommand option that allows the client to obtain known_hosts data from a command in addition to the usual files. * ssh(1): add a ssh_config PermitRemoteOpen option that allows the client to restrict the destination when RemoteForward is used with SOCKS. * ssh(1): for FIDO keys, if a signature operation fails with a "incorrect PIN" reason and no PIN was initially requested from the user, then request a PIN and retry the operation. This supports some biometric devices that fall back to requiring PIN when reading of the biometric failed, and devices that require PINs for all hosted credentials. * sshd(8): implement client address-based rate-limiting via new sshd_config(5) PerSourceMaxStartups and PerSourceNetBlockSize directives that provide more fine-grained control on a per-origin address basis than the global MaxStartups limit. Bugfixes -------- * ssh(1): Prefix keyboard interactive prompts with "(user@host)" to make it easier to determine which connection they are associated with in cases like scp -3, ProxyJump, etc. bz#3224 * sshd(8): fix sshd_config SetEnv directives located inside Match blocks. GHPR201 * ssh(1): when requesting a FIDO token touch on stderr, inform the user once the touch has been recorded. * ssh(1): prevent integer overflow when ridiculously large ConnectTimeout values are specified, capping the effective value (for most platforms) at 24 days. bz#3229 * ssh(1): consider the ECDSA key subtype when ordering host key algorithms in the client. * ssh(1), sshd(8): rename the PubkeyAcceptedKeyTypes keyword to PubkeyAcceptedAlgorithms. The previous name incorrectly suggested that it control allowed key algorithms, when this option actually specifies the signature algorithms that are accepted. The previous name remains available as an alias. bz#3253 * ssh(1), sshd(8): similarly, rename HostbasedKeyTypes (ssh) and HostbasedAcceptedKeyTypes (sshd) to HostbasedAcceptedAlgorithms. * sftp-server(8): add missing lsetstat@openssh.com documentation and advertisement in the server's SSH2_FXP_VERSION hello packet. * ssh(1), sshd(8): more strictly enforce KEX state-machine by banning packet types once they are received. Fixes memleak caused by duplicate SSH2_MSG_KEX_DH_GEX_REQUEST (oss-fuzz #30078). * sftp(1): allow the full range of UIDs/GIDs for chown/chgrp on 32bit platforms instead of being limited by LONG_MAX. bz#3206 * Minor man page fixes (capitalization, commas, etc.) bz#3223 * sftp(1): when doing an sftp recursive upload or download of a read-only directory, ensure that the directory is created with write and execute permissions in the interim so that the transfer can actually complete, then set the directory permission as the final step. bz#3222 * ssh-keygen(1): document the -Z, check the validity of its argument earlier and provide a better error message if it's not correct. bz#2879 * ssh(1): ignore comments at the end of config lines in ssh_config, similar to what we already do for sshd_config. bz#2320 * sshd_config(5): mention that DisableForwarding is valid in a sshd_config Match block. bz3239 * sftp(1): fix incorrect sorting of "ls -ltr" under some circumstances. bz3248. * ssh(1), sshd(8): fix potential integer truncation of (unlikely) timeout values. bz#3250 * ssh(1): make hostbased authentication send the signature algorithm in its SSH2_MSG_USERAUTH_REQUEST packets instead of the key type. This make HostbasedAcceptedAlgorithms do what it is supposed to - filter on signature algorithm and not key type. Portability ----------- * sshd(8): add a number of platform-specific syscalls to the Linux seccomp-bpf sandbox. bz#3232 bz#3260 * sshd(8): remove debug message from sigchld handler that could cause deadlock on some platforms. bz#3259 * Sync contrib/ssh-copy-id with upstream. * unittests: add a hostname function for systems that don't have it. Some systems don't have a hostname command (it's not required by POSIX). The do have uname -n (which is), but not all of those have it report the FQDN.

OpenSSH 8.3 was released on 2020-05-27. It is available from the mirrors listed at https://www.openssh.com/. OpenSSH is a 100% complete SSH protocol 2.0 implementation and includes sftp client and server support. Once again, we would like to thank the OpenSSH community for their continued support of the project, especially those who contributed code or patches, reported bugs, tested snapshots or donated to the project. More information on donations may be found at: https://www.openssh.com/donations.html Future deprecation notice ========================= It is now possible[1] to perform chosen-prefix attacks against the SHA-1 algorithm for less than USD$50K. For this reason, we will be disabling the "ssh-rsa" public key signature algorithm by default in a near-future release. This algorithm is unfortunately still used widely despite the existence of better alternatives, being the only remaining public key signature algorithm specified by the original SSH RFCs. The better alternatives include: * The RFC8332 RSA SHA-2 signature algorithms rsa-sha2-256/512. These algorithms have the advantage of using the same key type as "ssh-rsa" but use the safe SHA-2 hash algorithms. These have been supported since OpenSSH 7.2 and are already used by default if the client and server support them. * The ssh-ed25519 signature algorithm. It has been supported in OpenSSH since release 6.5. * The RFC5656 ECDSA algorithms: ecdsa-sha2-nistp256/384/521. These have been supported by OpenSSH since release 5.7. To check whether a server is using the weak ssh-rsa public key algorithm, for host authentication, try to connect to it after removing the ssh-rsa algorithm from ssh(1)'s allowed list: ssh -oHostKeyAlgorithms=-ssh-rsa user@host If the host key verification fails and no other supported host key types are available, the server software on that host should be upgraded. A future release of OpenSSH will enable UpdateHostKeys by default to allow the client to automatically migrate to better algorithms. Users may consider enabling this option manually. Vendors of devices that implement the SSH protocol should ensure that they support the new signature algorithms for RSA keys. [1] "SHA-1 is a Shambles: First Chosen-Prefix Collision on SHA-1 and Application to the PGP Web of Trust" Leurent, G and Peyrin, T (2020) https://eprint.iacr.org/2020/014.pdf Security ======== * scp(1): when receiving files, scp(1) could be become desynchronised if a utimes(2) system call failed. This could allow file contents to be interpreted as file metadata and thereby permit an adversary to craft a file system that, when copied with scp(1) in a configuration that caused utimes(2) to fail (e.g. under a SELinux policy or syscall sandbox), transferred different file names and contents to the actual file system layout. Exploitation of this is not likely as utimes(2) does not fail under normal circumstances. Successful exploitation is not silent - the output of scp(1) would show transfer errors followed by the actual file(s) that were received. Finally, filenames returned from the peer are (since openssh-8.0) matched against the user's requested destination, thereby disallowing a successful exploit from writing files outside the user's selected target glob (or directory, in the case of a recursive transfer). This ensures that this attack can achieve no more than a hostile peer is already able to achieve within the scp protocol. Potentially-incompatible changes ================================ This release includes a number of changes that may affect existing configurations: * sftp(1): reject an argument of "-1" in the same way as ssh(1) and scp(1) do instead of accepting and silently ignoring it. Changes since OpenSSH 8.2 ========================= The focus of this release is bug fixing. New Features ------------ * sshd(8): make IgnoreRhosts a tri-state option: "yes" to ignore rhosts/shosts, "no" allow rhosts/shosts or (new) "shosts-only" to allow .shosts files but not .rhosts. * sshd(8): allow the IgnoreRhosts directive to appear anywhere in a sshd_config, not just before any Match blocks; bz3148 * ssh(1): add %TOKEN percent expansion for the LocalFoward and RemoteForward keywords when used for Unix domain socket forwarding. bz#3014 * all: allow loading public keys from the unencrypted envelope of a private key file if no corresponding public key file is present. * ssh(1), sshd(8): prefer to use chacha20 from libcrypto where possible instead of the (slower) portable C implementation included in OpenSSH. * ssh-keygen(1): add ability to dump the contents of a binary key revocation list via "ssh-keygen -lQf /path" bz#3132 Bugfixes -------- * ssh(1): fix IdentitiesOnly=yes to also apply to keys loaded from a PKCS11Provider; bz#3141 * ssh-keygen(1): avoid NULL dereference when trying to convert an invalid RFC4716 private key. * scp(1): when performing remote-to-remote copies using "scp -3", start the second ssh(1) channel with BatchMode=yes enabled to avoid confusing and non-deterministic ordering of prompts. * ssh(1), ssh-keygen(1): when signing a challenge using a FIDO token, perform hashing of the message to be signed in the middleware layer rather than in OpenSSH code. This permits the use of security key middlewares that perform the hashing implicitly, such as Windows Hello. * ssh(1): fix incorrect error message for "too many known hosts files." bz#3149 * ssh(1): make failures when establishing "Tunnel" forwarding terminate the connection when ExitOnForwardFailure is enabled; bz#3116 * ssh-keygen(1): fix printing of fingerprints on private keys and add a regression test for same. * sshd(8): document order of checking AuthorizedKeysFile (first) and AuthorizedKeysCommand (subsequently, if the file doesn't match); bz#3134 * sshd(8): document that /etc/hosts.equiv and /etc/shosts.equiv are not considered for HostbasedAuthentication when the target user is root; bz#3148 * ssh(1), ssh-keygen(1): fix NULL dereference in private certificate key parsing (oss-fuzz #20074). * ssh(1), sshd(8): more consistency between sets of %TOKENS are accepted in various configuration options. * ssh(1), ssh-keygen(1): improve error messages for some common PKCS#11 C_Login failure cases; bz#3130 * ssh(1), sshd(8): make error messages for problems during SSH banner exchange consistent with other SSH transport-layer error messages and ensure they include the relevant IP addresses bz#3129 * various: fix a number of spelling errors in comments and debug/error messages * ssh-keygen(1), ssh-add(1): when downloading FIDO2 resident keys from a token, don't prompt for a PIN until the token has told us that it needs one. Avoids double-prompting on devices that implement on-device authentication. * sshd(8), ssh-keygen(1): no-touch-required FIDO certificate option should be an extension, not a critical option. * ssh(1), ssh-keygen(1), ssh-add(1): offer a better error message when trying to use a FIDO key function and SecurityKeyProvider is empty. * ssh-add(1), ssh-agent(8): ensure that a key lifetime fits within the values allowed by the wire format (u32). Prevents integer wraparound of the timeout values. bz#3119 * ssh(1): detect and prevent trivial configuration loops when using ProxyJump. bz#3057. Portability ----------- * Detect systems where signals flagged with SA_RESTART will interrupt select(2). POSIX permits implementations to choose whether select(2) will return when interrupted with a SA_RESTART-flagged signal, but OpenSSH requires interrupting behaviour. * Several compilation fixes for HP/UX and AIX. * On platforms that do not support setting process-wide routing domains (all excepting OpenBSD at present), fail to accept a configuration attempts to set one at process start time rather than fatally erroring at run time. bz#3126 * Improve detection of egrep (used in regression tests) on platforms that offer a poor default one (e.g. Solaris). * A number of shell portability fixes for the regression tests. * Fix theoretical infinite loop in the glob(3) replacement implementation. * Fix seccomp sandbox compilation problems for some Linux configurations bz#3085 * Improved detection of libfido2 and some compilation fixes for some configurations when --with-security-key-builtin is selected.

OpenSSH 7.7 was released on 2018-04-02. It is available from the mirrors listed at http://www.openssh.com/ shortly. OpenSSH is a 100% complete SSH protocol 2.0 implementation and includes sftp client and server support. Once again, we would like to thank the OpenSSH community for their continued support of the project, especially those who contributed code or patches, reported bugs, tested snapshots or donated to the project. More information on donations may be found at: http://www.openssh.com/donations.html Potentially-incompatible changes ================================ This release includes a number of changes that may affect existing configurations: * ssh(1)/sshd(8): Drop compatibility support for some very old SSH implementations, including ssh.com <=2.* and OpenSSH <= 3.*. These versions were all released in or before 2001 and predate the final SSH RFCs. The support in question isn't necessary for RFC-compliant SSH implementations. Changes since OpenSSH 7.6 ========================= This is primarily a bugfix release. New Features ------------ * All: Add experimental support for PQC XMSS keys (Extended Hash- Based Signatures) based on the algorithm described in https://tools.ietf.org/html/draft-irtf-cfrg-xmss-hash-based-signatures-12 The XMSS signature code is experimental and not compiled in by default. * sshd(8): Add a "rdomain" criteria for the sshd_config Match keyword to allow conditional configuration that depends on which routing domain a connection was received on (currently supported on OpenBSD and Linux). * sshd_config(5): Add an optional rdomain qualifier to the ListenAddress directive to allow listening on different routing domains. This is supported only on OpenBSD and Linux at present. * sshd_config(5): Add RDomain directive to allow the authenticated session to be placed in an explicit routing domain. This is only supported on OpenBSD at present. * sshd(8): Add "expiry-time" option for authorized_keys files to allow for expiring keys. * ssh(1): Add a BindInterface option to allow binding the outgoing connection to an interface's address (basically a more usable BindAddress) * ssh(1): Expose device allocated for tun/tap forwarding via a new %T expansion for LocalCommand. This allows LocalCommand to be used to prepare the interface. * sshd(8): Expose the device allocated for tun/tap forwarding via a new SSH_TUNNEL environment variable. This allows automatic setup of the interface and surrounding network configuration automatically on the server. * ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp, e.g. ssh://user@host or sftp://user@host/path. Additional connection parameters described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not implemented since the ssh fingerprint format in the draft uses the deprecated MD5 hash with no way to specify the any other algorithm. * ssh-keygen(1): Allow certificate validity intervals that specify only a start or stop time (instead of both or neither). * sftp(1): Allow "cd" and "lcd" commands with no explicit path argument. lcd will change to the local user's home directory as usual. cd will change to the starting directory for session (because the protocol offers no way to obtain the remote user's home directory). bz#2760 * sshd(8): When doing a config test with sshd -T, only require the attributes that are actually used in Match criteria rather than (an incomplete list of) all criteria. Bugfixes -------- * ssh(1)/sshd(8): More strictly check signature types during key exchange against what was negotiated. Prevents downgrade of RSA signatures made with SHA-256/512 to SHA-1. * sshd(8): Fix support for client that advertise a protocol version of "1.99" (indicating that they are prepared to accept both SSHv1 and SSHv2). This was broken in OpenSSH 7.6 during the removal of SSHv1 support. bz#2810 * ssh(1): Warn when the agent returns a ssh-rsa (SHA1) signature when a rsa-sha2-256/512 signature was requested. This condition is possible when an old or non-OpenSSH agent is in use. bz#2799 * ssh-agent(1): Fix regression introduced in 7.6 that caused ssh-agent to fatally exit if presented an invalid signature request message. * sshd_config(5): Accept yes/no flag options case-insensitively, as has been the case in ssh_config(5) for a long time. bz#2664 * ssh(1): Improve error reporting for failures during connection. Under some circumstances misleading errors were being shown. bz#2814 * ssh-keyscan(1): Add -D option to allow printing of results directly in SSHFP format. bz#2821 * regress tests: fix PuTTY interop test broken in last release's SSHv1 removal. bz#2823 * ssh(1): Compatibility fix for some servers that erroneously drop the connection when the IUTF8 (RFC8160) option is sent. * scp(1): Disable RemoteCommand and RequestTTY in the ssh session started by scp (sftp was already doing this.) * ssh-keygen(1): Refuse to create a certificate with an unusable number of principals. * ssh-keygen(1): Fatally exit if ssh-keygen is unable to write all the public key during key generation. Previously it would silently ignore errors writing the comment and terminating newline. * ssh(1): Do not modify hostname arguments that are addresses by automatically forcing them to lower-case. Instead canonicalise them to resolve ambiguities (e.g. ::0001 => ::1) before they are matched against known_hosts. bz#2763 * ssh(1): Don't accept junk after "yes" or "no" responses to hostkey prompts. bz#2803 * sftp(1): Have sftp print a warning about shell cleanliness when decoding the first packet fails, which is usually caused by shells polluting stdout of non-interactive startups. bz#2800 * ssh(1)/sshd(8): Switch timers in packet code from using wall-clock time to monotonic time, allowing the packet layer to better function over a clock step and avoiding possible integer overflows during steps. * Numerous manual page fixes and improvements. Portability ----------- * sshd(8): Correctly detect MIPS ABI in use at configure time. Fixes sandbox violations on some environments. * sshd(8): Remove UNICOS support. The hardware and software are literal museum pieces and support in sshd is too intrusive to justify maintaining. * All: Build and link with "retpoline" flags when available to mitigate the "branch target injection" style (variant 2) of the Spectre branch-prediction vulnerability. * All: Add auto-generated dependency information to Makefile. * Numerous fixed to the RPM spec files.
