9.10.x prior to 9.10.5-P1, or 9.11.x prior to 9.11.1-P1. It is,
therefore, affected by multiple vulnerabilities :

  - A denial of service vulnerability exists when processing
    Response Policy Zone (RPZ) rule types. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted query, to cause an infinite loop
    condition that degrades the server's functionality.
    (CVE-2017-3140)

  - A privilege escalation vulnerability exists in the BIND
    installer for Windows due to using an unquoted service
    path. A local attacker can exploit this to gain elevated
    privileges provided that the host file system
    permissions allow this. Note that non-Windows builds and
    installations are not affected. (CVE-2017-3141)");
