CVE-2019-6465: Zone transfer controls for writable DLZ zones were not effective

First published: Wed Feb 20 2019(Updated: )

ISC BIND could allow a remote attacker to obtain sensitive information, caused by the failure to properly apply controls for zone transfers to Dynamically Loadable Zones (DLZs) if the zones are writable. An attacker could exploit this vulnerability to request and receive a zone transfer of a DLZ even when not permitted to do so by the allow-transfer ACL.
