Red Hat Security Advisory

Synopsis: Important: 389-ds-base security, bug fix, and enhancement
update
Advisory ID: RHSA-2015:0416-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-0416.html
Issue date: 2015-03-05
CVE Names: CVE-2014-8105 CVE-2014-8112
=====================================================================

1. Summary:

Updated 389-ds-base packages that fix two security issues, several bugs,
and add various enhancements are now available for Red Hat Enterprise
Linux 7.

Red Hat Product Security has rated this update as having Important security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

2. Relevant releases/architectures:

3. Description:

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

An information disclosure flaw was found in the way the 389 Directory
Server stored information in the Changelog that is exposed via the
'cn=changelog' LDAP sub-tree. An unauthenticated user could in certain
cases use this flaw to read data from the Changelog, which could include
sensitive information such as plain-text passwords.
(CVE-2014-8105)

It was found that when the nsslapd-unhashed-pw-switch 389 Directory Server
configuration option was set to "off", it did not prevent the writing
of
unhashed passwords into the Changelog. This could potentially allow an
authenticated user able to access the Changelog to read sensitive
information. (CVE-2014-8112)

The CVE-2014-8105 issue was discovered by Petr Špaček of the Red Hat
Identity Management Engineering Team, and the CVE-2014-8112 issue was
discovered by Ludwig Krispenz of the Red Hat Identity Management
Engineering Team.

Enhancements:

* Added new WinSync configuration parameters: winSyncSubtreePair for
synchronizing multiple subtrees, as well as winSyncWindowsFilter and
winSyncDirectoryFilter for synchronizing restricted sets by filters.
(BZ#746646)

* It is now possible to stop, start, or configure plug-ins without the need
to restart the server for the change to take effect. (BZ#994690)

* Access control related to the MODDN and MODRDN operations has been
updated: the source and destination targets can be specified in the same
access control instruction. (BZ#1118014)

* The nsDS5ReplicaBindDNGroup attribute for using a group distinguished
name in binding to replicas has been added. (BZ#1052754)

* WinSync now supports range retrieval. If more than the MaxValRange number
of attribute values exist per attribute, WinSync synchronizes all the
attributes to the directory server using the range retrieval. (BZ#1044149)

* Support for the RFC 4527 Read Entry Controls and RFC 4533 Content
Synchronization Operation LDAP standards has been added. (BZ#1044139,
BZ#1044159)

* The Referential Integrity (referint) plug-in can now use an alternate
configuration area. The PlugInArg plug-in configuration now uses unique
configuration attributes. Configuration changes no longer require a server
restart. (BZ#1044203)

* The logconv.pl log analysis tool now supports gzip, bzip2, and xz
compressed files and also TAR archives and compressed TAR archives of these
files. (BZ#1044188)

* Only the Directory Manager could add encoded passwords or force users to
change their password after a reset. Users defined in the passwordAdminDN
attribute can now also do this. (BZ#1118007)

* The "nsslapd-memberofScope" configuration parameter has been added to
the
MemberOf plug-in. With MemberOf enabled and a scope defined, moving a group
out of scope with a MODRDN operation failed. Moving a member entry out of
scope now correctly removes the memberof value. (BZ#1044170)

* The alwaysRecordLoginAttr attribute has been addded to the Account Policy
plug-in configuration entry, which allows to distinguish between an
attribute for checking the activity of an account and an attribute to be
updated at successful login. (BZ#1060032)

* A root DSE search, using the ldapsearch command with the '-s base -b
""'
options, returns only the user attributes instead of the operational
attributes. The "nsslapd-return-default" option has been added for
backward
compatibility. (BZ#1118021)

* The configuration of the MemberOf plug-in can be stored in a suffix
mapped to a back-end database, which allows MemberOf configuration to be
replicated. (BZ#1044205)

* Added support for the SSL versions from the range supported by the NSS
library available on the system. Due to the POODLE vulnerability, SSLv3 is
disabled by default even if NSS supports it. (BZ#1044191)

4. Solution:

All 389-ds-base users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues and add these
enhancements. After installing this update, the 389 server service will be
restarted automatically.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
