Tenable has extracted the preceding description block directly from the Oracle 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.

Update to upstream 3.1.3.

Add fix for CVE-2013-0336 389-ds-base: DoS when connecting with a missing username/dn

Add fix for CVE-2013-1897: unintended information exposure when nsslapd-allow-anonymous-access is set to rootdse

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.

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 release fixes 7 critical bugs including one security bug.

Updated 389-ds-base packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link 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.

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.
