How to fix?

Upgrade Debian:8 openldap to version 2.4.23-1 or higher.

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:8 relevant fixed versions and status.

OpenLDAP 2.4.22 allows remote attackers to cause a denial of service (crash) via a modrdn call with a zero-length RDN destination string, which is not properly handled by the smr_normalize function and triggers a NULL pointer dereference in the IA5StringNormalize function in schema_init.c, as demonstrated using the Codenomicon LDAPv3 test suite.
