How to fix?

There is no fixed version for Debian:9 openldap.

NVD Description

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

libldap in certain third-party OpenLDAP packages has a certificate-validation flaw when the third-party package is asserting RFC6125 support. It considers CN even when there is a non-matching subjectAltName (SAN). This is fixed in, for example, openldap-2.4.46-10.el8 in Red Hat Enterprise Linux.
