Accepting request 922068 from home:hpjansson:branches:network - Version upgrade to 8.8p1 * No changes for askpass, see main package changelog for details - Version update to 8.8p1: = Security * sshd(8) from OpenSSH 6.2 through 8.7 failed to correctly initialise supplemental groups when executing an AuthorizedKeysCommand or AuthorizedPrincipalsCommand, where a AuthorizedKeysCommandUser or AuthorizedPrincipalsCommandUser directive has been set to run the command as a different user. Instead these commands would inherit the groups that sshd(8) was started with. Depending on system configuration, inherited groups may allow AuthorizedKeysCommand/AuthorizedPrincipalsCommand helper programs to gain unintended privilege. Neither AuthorizedKeysCommand nor AuthorizedPrincipalsCommand are enabled by default in sshd_config(5). = Potentially-incompatible changes * This release disables RSA signatures using the SHA-1 hash algorithm by default. This change has been made as the SHA-1 hash algorithm is cryptographically broken, and it is possible to create chosen-prefix hash collisions for <USD$50K. For most users, this change should be invisible and there is no need to replace ssh-rsa keys. OpenSSH has supported RFC8332 RSA/SHA-256/512 signatures since release 7.2 and existing ssh-rsa keys will automatically use the stronger algorithm where possible. Incompatibility is more likely when connecting to older SSH implementations that have not been upgraded or have not closely tracked improvements in the SSH protocol. For these cases, it may be necessary to selectively re-enable RSA/SHA1 to allow connection and/or user authentication via the HostkeyAlgorithms and PubkeyAcceptedAlgorithms options. = New features * ssh(1): allow the ssh_config(5) CanonicalizePermittedCNAMEs directive to accept a "none" argument to specify the default behaviour. = Bugfixes * scp(1): when using the SFTP protocol, continue transferring files after a transfer error occurs, better matching original scp/rcp behaviour. * ssh(1): fixed a number of memory leaks in multiplexing, * ssh-keygen(1): avoid crash when using the -Y find-principals command. * A number of documentation and manual improvements, including bz#3340, PR139, PR215, PR241, PR257 - Additional changes from 8.7p1 release: = Potentially-incompatible changes * scp(1): this release changes the behaviour of remote to remote copies (e.g. "scp host-a:/path host-b:") to transfer through the local host by default. This was previously available via the -3 flag. This mode avoids the need to expose credentials on the origin hop, avoids triplicate interpretation of filenames by the shell (by the local system, the copy origin and the destination) and, in conjunction with the SFTP support for scp(1) mentioned below, allows use of all authentication methods to the remote hosts (previously, only non-interactive methods could be used). A -R flag has been added to select the old behaviour. * ssh(1)/sshd(8): both the client and server are now using a stricter configuration file parser. The new parser uses more shell-like rules for quotes, space and escape characters. It is also more strict in rejecting configurations that include options lacking arguments. Previously some options (e.g. DenyUsers) could appear on a line with no subsequent arguments. This release will reject such configurations. The new parser will also reject configurations with unterminated quotes and multiple '=' characters after the option name. * ssh(1): when using SSHFP DNS records for host key verification, ssh(1) will verify all matching records instead of just those with the specific signature type requested. This may cause host key verification problems if stale SSHFP records of a different or legacy signature type exist alongside other records for a particular host. bz#3322 * ssh-keygen(1): when generating a FIDO key and specifying an explicit attestation challenge (using -Ochallenge), the challenge will now be hashed by the builtin security key middleware. This removes the (undocumented) requirement that challenges be exactly 32 bytes in length and matches the expectations of libfido2. * sshd(8): environment="..." directives in authorized_keys files are now first-match-wins and limited to 1024 discrete environment variable names. = New features * scp(1): experimental support for transfers using the SFTP protocol as a replacement for the venerable SCP/RCP protocol that it has traditionally used. SFTP offers more predictable filename handling and does not require expansion of glob(3) patterns via the shell on the remote side. * sftp-server(8): add a protocol extension to support expansion of ~/ and ~user/ prefixed paths. This was added to support these paths when used by scp(1) while in SFTP mode. * ssh(1): add a ForkAfterAuthentication ssh_config(5) counterpart to the ssh(1) -f flag. GHPR231 * ssh(1): add a StdinNull directive to ssh_config(5) that allows the config file to do the same thing as -n does on the ssh(1) command- line. GHPR231 * ssh(1): add a SessionType directive to ssh_config, allowing the configuration file to offer equivalent control to the -N (no session) and -s (subsystem) command-line flags. GHPR231 * ssh-keygen(1): allowed signers files used by ssh-keygen(1) signatures now support listing key validity intervals alongside they key, and ssh-keygen(1) can optionally check during signature verification whether a specified time falls inside this interval. This feature is intended for use by git to support signing and verifying objects using ssh keys. * ssh-keygen(8): support printing of the full public key in a sshsig signature via a -Oprint-pubkey flag. = Bugfixes * ssh(1)/sshd(8): start time-based re-keying exactly on schedule in the client and server mainloops. Previously the re-key timeout could expire but re-keying would not start until a packet was sent or received, causing a spin in select() if the connection was quiescent. * ssh-keygen(1): avoid Y2038 problem in printing certificate validity lifetimes. Dates past 2^31-1 seconds since epoch were displayed incorrectly on some platforms. bz#3329 * scp(1): allow spaces to appear in usernames for local to remote and scp -3 remote to remote copies. bz#1164 * ssh(1)/sshd(8): remove references to ChallengeResponseAuthentication in favour of KbdInteractiveAuthentication. The former is what was in SSHv1, the latter is what is in SSHv2 (RFC4256) and they were treated as somewhat but not entirely equivalent. We retain the old name as a deprecated alias so configuration files continue to work as well as a reference in the man page for people looking for it. bz#3303 * ssh(1)/ssh-add(1)/ssh-keygen(1): fix decoding of X.509 subject name when extracting a key from a PKCS#11 certificate. bz#3327 * ssh(1): restore blocking status on stdio fds before close. ssh(1) needs file descriptors in non-blocking mode to operate but it was not restoring the original state on exit. This could cause problems with fds shared with other programs via the shell, bz#3280 and GHPR246 * ssh(1)/sshd(8): switch both client and server mainloops from select(3) to pselect(3). Avoids race conditions where a signal may arrive immediately before select(3) and not be processed until an event fires. bz#2158 * ssh(1): sessions started with ControlPersist were incorrectly executing a shell when the -N (no shell) option was specified. bz#3290 * ssh(1): check if IPQoS or TunnelDevice are already set before overriding. Prevents values in config files from overriding values supplied on the command line. bz#3319 * ssh(1): fix debug message when finding a private key to match a certificate being attempted for user authentication. Previously it would print the certificate's path, whereas it was supposed to be showing the private key's path. GHPR247 * sshd(8): match host certificates against host public keys, not private keys. Allows use of certificates with private keys held in a ssh-agent. bz#3524 * ssh(1): add a workaround for a bug in OpenSSH 7.4 sshd(8), which allows RSA/SHA2 signatures for public key authentication but fails to advertise this correctly via SSH2_MSG_EXT_INFO. This causes clients of these server to incorrectly match PubkeyAcceptedAlgorithmse and potentially refuse to offer valid keys. bz#3213 * sftp(1)/scp(1): degrade gracefully if a sftp-server offers the limits@openssh.com extension but fails when the client tries to invoke it. bz#3318 * ssh(1): allow ssh_config SetEnv to override $TERM, which is otherwise handled specially by the protocol. Useful in ~/.ssh/config to set TERM to something generic (e.g. "xterm" instead of "xterm-256color") for destinations that lack terminfo entries. * sftp-server(8): the limits@openssh.com extension was incorrectly marked as an operation that writes to the filesystem, which made it unavailable in sftp-server read-only mode. bz#3318 * ssh(1): fix SEGV in UpdateHostkeys debug() message, triggered when the update removed more host keys than remain present. * Many manual page fixes. - Additional changes from 8.6p1 release: = Security * sshd(8): OpenSSH 8.5 introduced the LogVerbose keyword. When this option was enabled with a set of patterns that activated logging in code that runs in the low-privilege sandboxed sshd process, the log messages were constructed in such a way that printf(3) format strings could effectively be specified the low-privilege code. = New features * sftp-server(8): add a new limits@openssh.com protocol extension that allows a client to discover various server limits, including maximum packet size and maximum read/write length. * sftp(1): use the new limits@openssh.com extension (when available) to select better transfer lengths in the client. * sshd(8): Add ModuliFile keyword to sshd_config to specify the location of the "moduli" file containing the groups for DH-GEX. * unit tests: Add a TEST_SSH_ELAPSED_TIMES environment variable to enable printing of the elapsed time in seconds of each test. = Bugfixes * ssh_config(5), sshd_config(5): sync CASignatureAlgorithms lists in manual pages with the current default. GHPR174 * ssh(1): ensure that pkcs11_del_provider() is called before exit. GHPR234 * ssh(1), sshd(8): fix problems in string->argv conversion. Multiple backslashes were not being dequoted correctly and quoted space in the middle of a string was being incorrectly split. GHPR223 * ssh(1): return non-zero exit status when killed by signal; bz#3281 * sftp-server(8): increase maximum SSH2_FXP_READ to match the maximum packet size. Also handle zero-length reads that are not explicitly banned by the spec. - Additional changes from 8.5p1 release: = 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. = Potentially-incompatible changes * 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. * 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. = 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. * 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. - Rebased patches: * openssh-7.7p1-IPv6_X_forwarding.patch * openssh-7.7p1-X11_trusted_forwarding.patch * openssh-7.7p1-X_forward_with_disabled_ipv6.patch * openssh-7.7p1-cavstest-ctr.patch * openssh-7.7p1-cavstest-kdf.patch * openssh-7.7p1-disable_openssl_abi_check.patch * openssh-7.7p1-eal3.patch * openssh-7.7p1-enable_PAM_by_default.patch * openssh-7.7p1-fips.patch * openssh-7.7p1-fips_checks.patch * openssh-7.7p1-host_ident.patch * openssh-7.7p1-hostname_changes_when_forwarding_X.patch * openssh-7.7p1-ldap.patch * openssh-7.7p1-no_fork-no_pid_file.patch * openssh-7.7p1-pam_check_locks.patch * openssh-7.7p1-pts_names_formatting.patch * openssh-7.7p1-remove_xauth_cookies_on_exit.patch * openssh-7.7p1-seccomp_ipc_flock.patch * openssh-7.7p1-seccomp_stat.patch * openssh-7.7p1-send_locale.patch * openssh-7.7p1-sftp_force_permissions.patch * openssh-7.7p1-sftp_print_diagnostic_messages.patch * openssh-7.7p1-systemd-notify.patch * openssh-7.9p1-keygen-preserve-perms.patch * openssh-7.9p1-revert-new-qos-defaults.patch * openssh-8.0p1-gssapi-keyex.patch * openssh-8.1p1-audit.patch * openssh-8.1p1-seccomp-clock_gettime64.patch * openssh-8.1p1-seccomp-clock_nanosleep.patch * openssh-8.1p1-seccomp-clock_nanosleep_time64.patch * openssh-8.1p1-use-openssl-kdf.patch * openssh-8.4p1-vendordir.patch * openssh-fips-ensure-approved-moduli.patch * openssh-link-with-sk.patch * openssh-reenable-dh-group14-sha1-default.patch * openssh-whitelist-syscalls.patch - Removed openssh-fix-ssh-copy-id.patch (fixed upstream).

Accepting request 737034 from home:hpjansson:branches:network Version update to 8.1p1: * ssh-keygen(1): when acting as a CA and signing certificates with an RSA key, default to using the rsa-sha2-512 signature algorithm. Certificates signed by RSA keys will therefore be incompatible with OpenSSH versions prior to 7.2 unless the default is overridden (using "ssh-keygen -t ssh-rsa -s ..."). * ssh(1): Allow %n to be expanded in ProxyCommand strings * ssh(1), sshd(8): Allow prepending a list of algorithms to the default set by starting the list with the '^' character, E.g. "HostKeyAlgorithms ^ssh-ed25519" * ssh-keygen(1): add an experimental lightweight signature and verification ability. Signatures may be made using regular ssh keys held on disk or stored in a ssh-agent and verified against an authorized_keys-like list of allowed keys. Signatures embed a namespace that prevents confusion and attacks between different usage domains (e.g. files vs email). * ssh-keygen(1): print key comment when extracting public key from a private key. * ssh-keygen(1): accept the verbose flag when searching for host keys in known hosts (i.e. "ssh-keygen -vF host") to print the matching host's random-art signature too. * All: support PKCS8 as an optional format for storage of private keys to disk. The OpenSSH native key format remains the default, but PKCS8 is a superior format to PEM if interoperability with non-OpenSSH software is required, as it may use a less insecure key derivation function than PEM's. - Additional changes from 8.0p1 release: * scp(1): Add "-T" flag to disable client-side filtering of server file list. * sshd(8): Remove support for obsolete "host/port" syntax.
