=====================================================================

 

1. Summary:

 

Updated 389-ds-base packages that fix one security issue and several bugs

are now available for Red Hat Enterprise Linux 6.

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

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
