How to fix?

Upgrade Debian:10 openldap to version 2.4.28-1 or higher.

NVD Description

Note: Versions mentioned in the description apply to the upstream openldap package. See How to fix? for Debian:10 relevant versions.

Off-by-one error in the UTF8StringNormalize function in OpenLDAP 2.4.26 and earlier allows remote attackers to cause a denial of service (slapd crash) via a zero-length string that triggers a heap-based buffer overflow, as demonstrated using an empty postalAddressAttribute value in an LDIF entry.
