How to fix?

There is no fixed version for Debian:unstable openssh.

NVD Description

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

OpenSSH 4.6 and earlier, when ChallengeResponseAuthentication is enabled, allows remote attackers to determine the existence of user accounts by attempting to authenticate via S/KEY, which displays a different response if the user account exists, a similar issue to CVE-2001-1483.
