3. Description:

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access
Protocol) applications and development tools.

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)

It was found that the OpenLDAP back-ndb back end allowed successful
authentication to the root distinguished name (DN) when any string was
provided as a password. A remote user could use this flaw to access an
OpenLDAP directory if they knew the value of the root DN. Note: This issue
only affected OpenLDAP installations using the NDB back-end, which is only
available for Red Hat Enterprise Linux 6 via third-party software.
(CVE-2011-1025)

A flaw was found in the way OpenLDAP handled modify relative distinguished
name (modrdn) requests. A remote, unauthenticated user could use this flaw
to crash an OpenLDAP server via a modrdn request containing an empty old
RDN value. (CVE-2011-1081)

Users of OpenLDAP should upgrade to these updated packages, which contain
backported patches to resolve 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.
