Details

USN-4078-1 fixed several vulnerabilities in openldap. This update provides
the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.

Original advisory 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.
