Scientific Linux Security Update : openldap on SL5.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

A flaw was found in the way OpenLDAP handled authentication failures
being passed from an OpenLDAP slave to the master. If OpenLDAP was
configured with a chain overlay and it forwarded authentication
failures, OpenLDAP would bind to the directory as an anonymous user
and return success, rather than return failure on the authenticated
bind. This could allow a user on a system that uses LDAP for
authentication to log into a directory-based account without knowing
the password. (CVE-2011-1024)

This update also fixes the following bug :

- Previously, multiple concurrent connections to an
OpenLDAP server could cause the slapd service to
terminate unexpectedly with an assertion error. This
update adds mutexes to protect multiple threads from
accessing a structure with a connection, and the slapd
service no longer crashes. (BZ#677611)

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