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

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 (184.108.40.206). (BZ#1270020)
* 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.
* 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.
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).
For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.3 Release Notes linked from the References section.
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
After installing this update, the 389 server service will be restarted
