Updated openldap packages fix security vulnerabilities: It was discovered that OpenLDAP incorrectly handled rootDN delegation. A database administrator could use this issue to request authorization as an identity from another database, contrary to expectations (CVE-2019-13057).
It was discovered that OpenLDAP incorrectly handled SASL authentication and session encryption. After a first SASL bind was completed, it was possible to obtain access by performing simple binds, contrary to expectations (CVE-2019-13565).
