Also, always spawn the client with umask 0022 so a starting lacme(8) with a restrictive umask doesn't impede serving challenge files. + lacme: add 'owner' resp. 'mode' as (prefered) alias for 'chown' resp. 'chmod'. + lacme: split certificates using Net::SSLeay::PEM_* instead of calling openssl. + lacme: pass a temporary JSON file with the client configuration to the internal client, so it doesn't have to parse the INI file again. - lacme: in the [accountd] config, let lacme-accountd(1) do the %-expansion for 'config', not lacme(8) when building the command. - lacme-accountd: don't log debug messages unless --debug is set. - lacme: when getpwnam()/getgrnam()'s errno is 0, exclude it from error messages. - tests/drop-privileges: ensure failure to drop privileges yields an error instead of retaining root priviliges. - tests/cert-install: include tests for failing chown(2) due to unknown user/group name. - lacme: ignore empty values in settings 'chown', 'chmod', 'certificate' and 'certificate-chain'. - lacme: return an error when the 'mode'/'chown' isn't a number. - Makefile: replace '$(dir $@)' with '$(@D)'. - Test suite: Adjust against current Let's Encrypt staging environment. -- Guilhem Moulin Wed, 25 Jan 2023 03:23:51 +0100 lacme (0.8.0) upstream; * Breaking change: 'challenge-directory' now needs to be set to an *existing* directory (writable by the lacme client user). Since lacme(8) spawns a builtin webserver by default the change doesn't affect default configurations. Thanks to Benjamin Tietz for the idea and initial patch. * Breaking change: the 'iptables' option is now ignored unless the builtin webserver is used. * Unprivileged user/group for the internal client resp. webserver are now configurable at install time. * lacme: new flag `--force`, which aliases to `--min-days=-1`, i.e., forces renewal regardless of the expiration date of existing certificates. * Remove decomissioned intermediate CAs Authority X3 and X4 from the bundle. * Remove cross-signed intermediate CAs from the bundle and add the (self-signed) ISRG Root X1 and X2 instead. This allows us to fully validate provided X.509 chains using that self-contained bundle, regardless of which CAs is marqued as trusted under /etc/ssl/certs. This change bumps the minimum OpenSSL version to 1.1.0. * Breaking change: lacme(8) and lacme-accountd(1) respectively load their configuration file from /etc/lacme/lacme.conf resp. /etc/lacme/lacme-accountd.conf when running as root, and $XDG_CONFIG_HOME/lacme/lacme.conf resp. $XDG_CONFIG_HOME/lacme/lacme-accountd.conf when running as a normal user. There is no fallback to /etc anymore, and the lookup in the current directory as prefered choice is removed too. However lacme-accountd(1) can be used without configuration file under ~/.config/lacme as it treats a non-existent default location as an empty file. * The client, webserver, and accountd commands are now split on whitespace. This doesn't change the default behavior but allows using `ssh -T lacme@account.example.net lacme-accountd` to spawn a remote lacme-accountd server for instance. * Add test suite against Let's Encrypt's staging environment https://letsencrypt.org/docs/staging-environment/ . * lacme(8)'s 'config' option in the [accountd] section no longer have a default value. The previous default /etc/lacme/lacme-accountd.conf is still honored when root privileges are preserved (the default). * Deprecate setting 'privkey' in [accountd] section of the lacme(8) configuration file. One need to use the lacme-accountd(1) configuration file for that instead. * lacme(8): add %-specifiers support for --config=, --socket=, --config-certs= (and 'socket'/'config-certs'/'challenge-directory' configuration options *before* privilege drop; and for the [accountd] section 'command'/'config' configuration options *after* privilege drop). * lacme-accountd(1): add %-specifiers support for --config=, --socket= and --privkey= (and 'socket'/'privkey' configuration options). * lacme-accountd(1): base64url-decode incoming signature requests shown in messages to the standard error. * lacme-accountd(1): new setting 'logfile' to log (decoded) incoming signature requests to a file. * lacme-accountd(1): new setting 'keyid' to easily revoke all account management access from the client. + Improve nginx/apache2 snippets for direct serving of challenge files (with the new 'challenge-directory' logic symlinks can be disabled). + Split Nginx and Apapche2 static configuration snippets into seperate files. That way users prefering that over reverse-proxying can just source/enable the relevant files without having to uncomment anything. + Add support for TLS Feature extension from RFC 7633; this is mostly useful for OCSP Must-Staple. + client: use "lacme-client/$VERSION" as User-Agent header. + Consolidate error messages for consistency. + Sanitize environment when spawning the lacme client, webserver and accountd. + accountd: replace internal option --conn-fd=FD with flag --stdio. Using stdin/stdout makes it possible to tunnel the accountd connection through ssh. The new flag is documented to allow safe usage is authorized_keys(5) restrictions. + Remove dependency on List::Util (core module). + accountd: Pass JWA and JWK thumbprint via extended greeting data. This gives better forward flexibility. - lacme: delay webserver socket shutdown to after the process has terminated. - documentation: suggest to generate private key material with genpkey(1ssl); also suggest a command to generate an ECDSA key not just RSA; hint at which key algorithms are supported. - documentation: clarify that "file:/path/to/account.key" can point to a symmetrically-encrypted private key. - documentation: emphasize default values in the config file, and move the most common options ('hash', 'keyUsage', 'CAfile', 'min-days') to the default section. - Raise client timeout from 10 to 30s. - Remove dependency on Types::Serialiser. - client: fail immediately when the accountd is unreachable. - Makefile: set executable bit for $(bindir)/lacme-accountd and $(sbindir)/lacme. - client: avoid "Use of uninitialized value in pattern match (m//)" perl warnings when the accountd socket can't be reached. - webserver: reopen stdin from /dev/null. - Use 'acme-challenge.XXXXXXXXXX' as template for the temporary ACME challenge directory. - Set the DEBUG environment variable to 0/1 instead of ""/1. - Use File::Basename::dirname() to correctly extract the parent directory of the socket path. - client: Print Terms of Service URL for 'account' command. -- Guilhem Moulin Mon, 22 Feb 2021 03:19:57 +0100 lacme (0.7) upstream; * Breaking change: the certificate indicated by 'CAfile' is no longer used as is in 'certificate-chain' (along with the leaf cert). The chain returned by the ACME v2 endpoint is used instead.

When dropping privileges to a dedicated UID (recommended) only the ACME client could write to its current directory anyway, so following symlinks was not a serious vulnerability. - lacme(1), lacme-accountd(1): fix version number shown with --version. - client: remove potential race when creating ACME challenge response files. - When using open with mode "<&=" or ">&=", ensure the expression (fileno) is interpreted as an integer.
