Detail

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

- Ubuntu 19.04 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

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)

Update instructions:

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

Ubuntu 19.04:
slapd 2.4.47+dfsg-3ubuntu2.1

Ubuntu 18.04 LTS:
slapd 2.4.45+dfsg-1ubuntu1.3

Ubuntu 16.04 LTS:
slapd 2.4.42+dfsg-2ubuntu3.6

In general, a standard system update will make all the necessary changes.
