"From Red Hat Security Advisory 2016:2594 :

An update for 389-ds-base is now available for Red Hat Enterprise
Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

389 Directory Server is an LDAP version 3 (LDAPv3) compliant server.
The base packages include the Lightweight Directory Access Protocol
(LDAP) server and command-line utilities for server administration.

The following packages have been upgraded to a newer upstream version:
389-ds-base (1.3.5.10). (BZ#1270020)

Security Fix(es) :

* It was found that 389 Directory Server was vulnerable to a flaw in
which the default ACI (Access Control Instructions) could be read by
an anonymous user. This could lead to leakage of sensitive
information. (CVE-2016-5416)

* An information disclosure flaw was found in 389 Directory Server. A
user with no access to objects in certain LDAP sub-tree could send
LDAP ADD operations with a specific object name. The error message
returned to the user was different based on whether the target object
existed or not. (CVE-2016-4992)

* It was found that 389 Directory Server was vulnerable to a remote
password disclosure via timing attack. A remote attacker could
possibly use this flaw to retrieve directory server password after
many tries. (CVE-2016-5405)

The CVE-2016-5416 issue was discovered by Viktor Ashirov (Red Hat);
the CVE-2016-4992 issue was discovered by Petr Spacek (Red Hat) and
Martin Basti (Red Hat); and the CVE-2016-5405 issue was discovered by
William Brown (Red Hat).
