How to fix?

There is no fixed version for Centos:10 389-ds-base-snmp.

NVD Description

Note: Versions mentioned in the description apply only to the upstream 389-ds-base-snmp package and not the 389-ds-base-snmp package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

A flaw was found in 389-ds-base. The server does not discard plaintext bytes already buffered from a client connection when negotiating StartTLS, allowing an on-path attacker to inject a crafted LDAP message that is processed after the TLS upgrade and whose response is delivered to the client in place of the client's own pending operation's response, due to messageID collision. This can cause a client application to treat a failed authentication (bind) attempt as successful.
