Vendor Statements (disclaimer)

Official Statement from openldap.org (02/25/2015)

Note that the deref overlay is not enabled by default, so this vulnerability only affects sites that have explicitly configured their servers to load and enable the overlay. Since this overlay has never been documented, there are no sites outside of the OpenLDAP developer community with a legitimate reason to enable this module.
