How to fix?

There is no fixed version for Debian:9 inetutils.

NVD Description

Note: Versions mentioned in the description apply only to the upstream inetutils package and not the inetutils package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

The ftp client in GNU Inetutils before 2.2 does not validate addresses returned by PASV/LSPV responses to make sure they match the server address. This is similar to CVE-2020-8284 for curl.
