389 Directory Server before 1.3.2.27 and 1.3.3.x before 1.3.3.9 does not properly restrict access to the "cn=changelog" LDAP sub-tree, which allows remote attackers to obtain sensitive information from the changelog via unspecified vectors.

Release 1.3.3.9 with security bug fixes

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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)

Enhancements :

  - Added new WinSync configuration parameters:
    winSyncSubtreePair for synchronizing multiple subtrees,     as well as winSyncWindowsFilter and     winSyncDirectoryFilter for synchronizing restricted sets     by filters.

  - It is now possible to stop, start, or configure plug-ins     without the need to restart the server for the change to     take effect.

  - 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.

  - The nsDS5ReplicaBindDNGroup attribute for using a group     distinguished name in binding to replicas has been     added.

  - 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.

  - Support for the RFC 4527 Read Entry Controls and RFC     4533 Content Synchronization Operation LDAP standards     has been added.

  - 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.

  - 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.

  - 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.

  - 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.

  - 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.

  - 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.

  - 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.

  - 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.

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.

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.

(CVE-2014-8105)

This update also fixes the following bugs :

  - In multi-master replication (MMR), deleting a     single-valued attribute of a Directory Server (DS) entry     was previously in some cases not correctly replicated.
    Consequently, the entry state in the replica systems did     not reflect the intended changes. This bug has been     fixed and the removal of a single-valued attribute is     now properly replicated.

  - Prior to this update, the Directory Server (DS) always     checked the ACI syntax. As a consequence, removing an     ACI failed with a syntax error. With this update, the     ACI check is stopped when the ACI is going to be     removed, and the removal thus works as expected.

In addition, this update adds the following enhancement :

  - The buffer size limit for the 389-ds-base application     has been increased to 2MB in order to match the buffer     size limit of Simple Authentication and Security Layer     (SASL) and Basic Encoding Rules (BER).

After installing this update, the 389 server service will be restarted automatically.
