Red Hat Security Advisory

 

Synopsis: Low: openldap security and bug fix update

Advisory ID: RHSA-2012:1151-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1151.html

Issue date: 2012-08-08

CVE Names: CVE-2012-2668

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

 

1. Summary:

 

Updated openldap packages that fix one security issue and one bug are now

3. Description:

 

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access

Protocol) applications and development tools.

 

It was found that the OpenLDAP server daemon ignored olcTLSCipherSuite

settings. This resulted in the default cipher suite always being used,

which could lead to weaker than expected ciphers being accepted during

Transport Layer Security (TLS) negotiation with OpenLDAP clients.

(CVE-2012-2668)

 

This update also fixes the following bug:

 

* When the smbk5pwd overlay was enabled in an OpenLDAP server, and a user

changed their password, the Microsoft NT LAN Manager (NTLM) and Microsoft

LAN Manager (LM) hashes were not computed correctly. This led to the

sambaLMPassword and sambaNTPassword attributes being updated with incorrect

values, preventing the user logging in using a Windows-based client or a

Samba client.

 

With this update, the smbk5pwd overlay is linked against OpenSSL. As such,

the NTLM and LM hashes are computed correctly, and password changes work as

expected when using smbk5pwd. (BZ#844428)

 

Users of OpenLDAP are advised to upgrade to these updated packages, which

contain backported patches to correct these issues. After installing this

update, the OpenLDAP daemons 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

https://access.redhat.com/knowledge/articles/11258

 

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

 

825875 - CVE-2012-2668 openldap: does not honor TLSCipherSuite settings

844428 - smbk5pwd module computes invalid NT and LM hashes
