At ISC we have recently received several inquiries from customers who are using the binary packages of BIND that we distribute for Microsoft Windows. They have expressed concerns about security vulnerabilities present in older versions of OpenSSL. BIND uses OpenSSL for securing communications between dynamic nameservers and clients and between master servers and slave servers. To support this functionality, ISC uses functionality from the OpenSSL libraries and ships libraries from the OpenSSL package with binary distributions of BIND.
