Synopsis: Moderate: 389-ds-base security, bug fix, and enhancement update
Advisory ID: SLSA-2016:2594-2
Issue Date: 2016-11-03
CVE Numbers: CVE-2016-4992

The following packages have been upgraded to a newer upstream version: 389
-ds-base (

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.

* 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).
