    Invoking bypass of certificate restrictions in golang.org/x/crypto/ssh

    When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil…

    Invoking byte arithmetic causes underflow and panic in golang.org/x/crypto/ssh

    An incorrectly placed cast from bytes to int allowed for server-side panic in the AES-GCM packet decoder for well-crafted inputs.

    Invoking agent constraints dropped when forwarding keys in golang.org/x/crypto/ssh/agent

    When adding a key to a remote agent constraint extensions such as restrict-destination-v00@openssh.com were not serialized in the request. Destination restrictions were silently stripped when forwarding keys, allowing unrestricted use of the key on the remote…

    Invoking key constraints not enforced in golang.org/x/crypto/ssh/agent

    The in-memory keyring returned by NewKeyring() silently accepted keys with the ConfirmBeforeUse constraint but never enforced it. The key would sign without any confirmation prompt, with no indication to the caller that the constraint was not in effect. NewKe…
