Scientific Linux Security Update : openldap on SL6.x i386/x86_64 (20120808)

medium Nessus Plugin ID 61455

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)

After installing this update, the OpenLDAP daemons will be restarted automatically.

Solution

Update the affected packages.
