There is no fixed version for RHEL:7 openldap-servers-sql.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openldap-servers-sql package and not the openldap-servers-sql package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In OpenLDAP through 2.4.57 and 2.5.x through 2.5.1alpha, an assertion failure in slapd can occur in the issuerAndThisUpdateCheck function via a crafted packet, resulting in a denial of service (daemon exit) via a short timestamp. This is related to schema_init.c and checkTime.
