How to fix?

There is no fixed version for Ubuntu:22.04 openssh-ssh1.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh-ssh1 package and not the openssh-ssh1 package as distributed by Ubuntu. See How to fix? for Ubuntu:22.04 relevant fixed versions and status.

internal-sftp in sshd in OpenSSH before 10.4 recognizes only the first 9 command-line arguments, which can be important if a later command-line argument would have helped to ensure the intended security properties of an SFTP connection.
