    Summary: openssh update

    Details: It was discovered that OpenSSH has an observable discrepancy leading to an information leak in the algorithm negotiation. This update mitigates the issue by tweaking the client hostkey preference ordering algorithm to prefer the default ordering if the user has a key that matches the best-preference default algorithm.
