  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.");
