==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

Summary:

Several security issues were fixed in OpenLDAP.

Software Description:
– openldap: OpenLDAP utilities

Details:

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)

The problem can be corrected by updating your system to the following
package versions:
