Synopsis

The remote Red Hat host is missing a security update for 389-ds-base.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:0742 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL 389-ds-base package based on the guidance in RHSA-2013:0742.
