OpenSSH 10.6 adds post-quantum signatures, speeds releases
OpenSSH 10.6 was released on October 6. It enables a hybrid post-quantum signature algorithm, weakens the Compression option to block a cross-channel attack, and fixes several other security issues. The maintainers also say they will publish releases more often for the time being.
OpenSSH is the open-source suite behind most remote logins on Linux, BSD and many other systems. It includes the sshd server, the ssh client, and tools such as sftp and ssh-keygen. Administrators running either the server or the client should expect updates on a shorter cycle than usual.
