RHEL 6 : 389-ds-base (RHSA-2017:0893)

medium Nessus Plugin ID 99339

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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)

Solution

Update the affected packages.
