Oracle Linux 6 : 389-ds-base (ELSA-2017-0893)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2017:0893 :

An update for 389-ds-base is now available for Red Hat Enterprise
Linux 6.

Red Hat Product Security has rated this update as having a security
impact of Important. 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.

Security Fix(es) :

* An invalid pointer dereference flaw was found in the way 389-ds-base
handled LDAP bind requests. A remote unauthenticated attacker could
use this flaw to make ns-slapd crash via a specially crafted LDAP bind
request, resulting in denial of service. (CVE-2017-2668)

Red Hat would like to thank Joachim Jabs (F24) for reporting this
issue.

Bug Fix(es) :

* Previously, the 'deref' plug-in failed to dereference attributes
that use distinguished name (DN) syntax, such as 'uniqueMember'. With
this patch, the 'deref' plug-in can dereference such attributes and
additionally 'Name and Optional UID' syntax. As a result, the 'deref'
plug-in now supports any syntax. (BZ#1435365)
