- update to 8.4p1: Security ======== * ssh-agent(1): restrict ssh-agent from signing web challenges for FIDO/U2F keys. * ssh-keygen(1): Enable FIDO 2.1 credProtect extension when generating a FIDO resident key. * ssh(1), ssh-keygen(1): support for FIDO keys that require a PIN for each use. These keys may be generated using ssh-keygen using a new "verify-required" option. When a PIN-required key is used, the user will be prompted for a PIN to complete the signature operation. New Features ------------ * sshd(8): authorized_keys now supports a new "verify-required" option to require FIDO signatures assert that the token verified that the user was present before making the signature. The FIDO protocol supports multiple methods for user-verification, but currently OpenSSH only supports PIN verification. * sshd(8), ssh-keygen(1): add support for verifying FIDO webauthn signatures. Webauthn is a standard for using FIDO keys in web browsers. These signatures are a slightly different format to plain FIDO signatures and thus require explicit support. * ssh(1): allow some keywords to expand shell-style ${ENV} environment variables. The supported keywords are CertificateFile, ControlPath, IdentityAgent and IdentityFile, plus LocalForward and RemoteForward when used for Unix domain socket paths. bz#3140 * ssh(1), ssh-agent(1): allow some additional control over the use of ssh-askpass via a new $SSH_ASKPASS_REQUIRE environment variable, including forcibly enabling and disabling its use. bz#69 * ssh(1): allow ssh_config(5)'s AddKeysToAgent keyword accept a time OBS-URL: https://build.opensuse.org/request/show/863944 OBS-URL: https://build.opensuse.org/package/show/network/openssh?expand=0&rev=222
