Summary: Updated openldap packages that fix one security issue and one bug 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. 2.

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.

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.
