Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4078-1 advisory.

 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
