## Description

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.
