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/RHSA-2013-0628.html

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_attr() function. The size of the leaks

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_attr() function.

(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:

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

 

910994 - PamConfig schema not updated during upgrade

910995 - Valgrind reports memleak in modify_update_last_modified_attr

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
