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.
 
It was found that the 389 Directory Server did not properly restrict access
to entries when the "nsslapd-allow-anonymous-access" configuration setting
was set to "rootdse". An anonymous user could connect to the LDAP database
and, if the search scope is set to BASE, obtain access to information
outside of the rootDSE. (CVE-2013-1897)

This issue was discovered by Martin Kosek of Red Hat.

This update also fixes the following bugs:

* Previously, the schema-reload plug-in was not thread-safe. Consequently,
executing the schema-reload.pl script under heavy load could have caused
the ns-slapd process to terminate unexpectedly with a segmentation fault.
Currently, the schema-reload plug-in is re-designed so that it is
thread-safe, and the schema-reload.pl script can be executed along with
other LDAP operations. (BZ#929107)

* An out of scope problem for a local variable, in some cases, caused the
modrdn operation to terminate unexpectedly with a segmentation fault. This
update declares the local variable at the proper place of the function so
it does not go out of scope, and the modrdn operation no longer crashes.
(BZ#929111)

* A task manually constructed an exact value to be removed from the
configuration if the "replica-force-cleaning" option was used.
Consequently, the task configuration was not cleaned up, and every time the
server was restarted, the task behaved in the described manner. This update
searches the configuration for the exact value to delete, instead of
manually building the value, and the task does not restart when the server
is restarted. (BZ#929114)

* Previously, a NULL pointer dereference could have occurred when
attempting to get effective rights on an entry that did not exist, leading
to an unexpected termination due to a segmentation fault. This update
checks for NULL entry pointers and returns the appropriate error. Now,
attempts to get effective rights on an entry that does not exist no longer
causes crashes, and the server returns the appropriate error message.
(BZ#929115)

* A problem in the lock timing in the DNA plug-in caused a deadlock if the
DNA operation was executed with other plug-ins. This update moves the
release timing of the problematic lock, and the DNA plug-in does not cause
the deadlock. (BZ#929196)

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

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

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

928105 - CVE-2013-1897 389-ds: unintended information exposure when rootdse is enabled
929111 - Crash in MODRDN
929114 - cleanAllRUV task fails to cleanup config upon completion
929115 - crash in aci evaluation
