Issue date: 2018-05-14
CVE Names: CVE-2018-1089
=====================================================================

1. Summary:

An update for 389-ds-base is now available for Red Hat Enterprise Linux 7.

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.

3. Description:

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):

* 389-ds-base: ns-slapd crash via large filter value in ldapsearch
(CVE-2018-1089)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Red Hat would like to thank Greg Kubok for reporting this issue.

Bug Fix(es):

* Indexing tasks in Directory Server contain the nsTaskStatus attribute to
monitor whether the task is completed and the database is ready to receive
updates. Before this update, the server set the value that indexing had
completed before the database was ready to receive updates. Applications
which monitor nsTaskStatus could start sending updates as soon as indexing
completed, but before the database was ready. As a consequence, the server
rejected updates with an UNWILLING_TO_PERFORM error. The problem has been
fixed. As a result, the nsTaskStatus attribute now shows that indexing is
completed after the database is ready to receive updates. (BZ#1553605)

* Previously, Directory Server did not remember when the first operation,
bind, or a connection was started. As a consequence, the server applied in
certain situations anonymous resource limits to an authenticated client.
With this update, Directory Server properly marks authenticated client
connections. As a result, it applies the correct resource limits, and
authenticated clients no longer get randomly restricted by anonymous
resource limits. (BZ#1554720)

* When debug replication logging is enabled, Directory Server incorrectly
logged an error that updating the replica update vector (RUV) failed when
in fact the update succeeded. The problem has been fixed, and the server no
longer logs an error if updating the RUV succeeds. (BZ#1559464)

* This update adds the -W option to the ds-replcheck utility. With this
option, ds-replcheck asks for the password, similar to OpenLDAP utilities.
As a result, the password is not stored in the shell’s history file when
the -W option is used. (BZ#1559760)

* If an administrator moves a group in Directory Server from one subtree to
another, the memberOf plug-in deletes the memberOf attribute with the old
value and adds a new memberOf attribute with the new group’s distinguished
name (DN) in affected user entries. Previously, if the old subtree was not
within the scope of the memberOf plug-in, deleting the old memberOf
attribute failed because the values did not exist. As a consequence, the
plug-in did not add the new memberOf value, and the user entry contained an
incorrect memberOf value. With this update, the plug-in now checks the
return code when deleting the old value. If the return code is “no such
value”, the plug-in only adds the new memberOf value. As a result, the
memberOf attribute information is correct. (BZ#1559764)

* In a Directory Server replication topology, updates are managed by using
Change Sequence Numbers (CSN) based on time stamps. New CSNs must be higher
than the highest CSN present in the relative update vector (RUV). In case
the server generates a new CSN in the same second as the most recent CSN,
the sequence number is increased to ensure that it is higher. However, if
the most recent CSN and the new CSN were identical, the sequence number was
not increased. In this situation, the new CSN was, except the replica ID,
identical to the most recent one. As a consequence, a new update in the
directory appeared in certain situations older than the most recent update.
With this update, Directory Server increases the CSN if the sequence number
is lower or equal to the most recent one. As a result, new updates are no
longer considered older than the most recent data. (BZ#1563079)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

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

5. Bugs fixed (https://bugzilla.redhat.com/):

1554720 – “Truncated search results” pop-up appears in user details in WebUI [rhel-7.5.z]
1559464 – replica_write_ruv log a failure even when it succeeds [rhel-7.5.z]
1559760 – ds-replcheck: add -W option to ask for the password from stdin instead of passing it on command line [rhel-7.5.z]
1559764 – memberof fails if group is moved into scope [rhel-7.5.z]
1559802 – CVE-2018-1089 389-ds-base: ns-slapd crash via large filter value in ldapsearch
1563079 – adjustment of csn_generator can fail so next generated csn can be equal to the most recent one received [rhel-7.5.z]
