NVD Description

Note: Versions mentioned in the description apply only to the upstream openldap package and not the openldap package as distributed by Alpine. See How to fix? for Alpine:3.10 relevant fixed versions and status.

A NULL pointer dereference was found in OpenLDAP server and was fixed in openldap 2.4.55, during a request for renaming RDNs. An unauthenticated attacker could remotely crash the slapd process by sending a specially crafted request, causing a Denial of Service.
