Synopsis: Moderate: 389-ds-base security and bug fix update
Advisory ID: RHSA-2013:0628-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/
Issue date: 2013-03-11
CVE Names: CVE-2013-0312
==============================
1. Summary:
Updated 389-ds-base packages that fix one security issue and multiple bugs
are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate
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.

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.
A flaw was found in the way LDAPv3 control data was handled by 389
Directory Server. If a malicious user were able to bind to the directory
(even anonymously) and send an LDAP request containing crafted LDAPv3
control data, they could cause the server to crash, denying service to the
directory. (CVE-2013-0312)
The CVE-2013-0312 issue was discovered by Thierry Bordaz of Red Hat.
This update also fixes the following bugs:
* After an upgrade from Red Hat Enterprise Linux 6.3 to version 6.4, the
upgrade script did not update the schema file for the PamConfig object
class. Consequently, new features for PAM such as configuration of multiple
instances and pamFilter attribute could not be used because of the schema
violation. With this update, the upgrade script updates the schema file for
the PamConfig object class and new features function properly. (BZ#910994)
* Previously, the valgrind test suite reported recurring memory leaks in
the modify_update_last_modified_
averaged between 60-80 bytes per modify call. In environments where modify
operations were frequent, this caused significant problems. Now, memory
leaks no longer occur in the modify_update_last_modified_
(BZ#910995)
* The Directory Server (DS) failed when multi-valued attributes were
replaced. The problem occurred when replication was enabled, while the
server executing the modification was configured as a single master and
there was at least one replication agreement. Consequently, the
modification requests were refused by the master server, which returned a
code 20 "Type or value exists" error message. These requests were
replacements of multi-valued attributes, and the error only occurred when
one of the new values matched one of the current values of the attribute,
but had a different letter case. Now, modification requests function
properly and no longer return code 20 errors. (BZ#910996)
* The DNA (distributed numeric assignment) plug-in, under certain
conditions, could log error messages with the "DB_LOCK_DEADLOCK" error
code when attempting to create an entry with a uidNumber attribute. Now,
DNA handles this case properly and errors no longer occur during attempts
to create entries with uidNumber attributes. (BZ#911467)
* Posix Winsync plugin was calling an internal modify function which was
not necessary. The internal modify call failed and logged an error message
"slapi_modify_internal_set_pb: NULL parameter" which was not clear. This
patch stops calling the internal modify function if it is not necessary and
the cryptic error message is not observed. (BZ#911468)
* Previously, under certain conditions, the dse.ldif file had 0 bytes after
a server termination or when the machine was powered off. Consequently,
after the system was brought up, a DS or IdM system could be unable to
restart, leading to production server outages. Now, the server mechanism by
which the dse.ldif is written is more robust, and tries all available
backup dse.ldif files, and outages no longer occur. (BZ#911469)
* Due to an incorrect interpretation of an error code, a directory server
considered an invalid chaining configuration setting as the disk full error
and shut down unexpectedly. Now, a more appropriate error code is in use
and the server no longer shuts down from invalid chaining configuration
settings. (BZ#911474)
* While trying to remove a tombstone entry, the ns-slapd daemon terminated
unexpectedly with a segmentation fault. With this update, removal of
tombstone entries no longer causes crashes. (BZ#914305)
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

5. Bugs fixed (http://bugzilla.redhat.com/):
910994 - PamConfig schema not updated during upgrade
910995 - Valgrind reports memleak in modify_update_last_modified_
911467 - DNA plugin acceptance tests failed with "DB_LOCK_DEADLOCK" error.
911468 - Error messages encountered when using POSIX winsync
911469 - dse.ldif is 0 length after server kill or machine kill
911474 - Invalid chaining config triggers a disk full error and shutdown
912964 - CVE-2013-0312 389-ds: unauthenticated denial of service vulnerability in handling of LDAPv3 control data
914305 - ns-slapd segfaults while trying to delete a tombstone entry
