EdDSA support is optional and currently defaults to being disabled.

The following security issues are addressed with this update:

  * An error in TSIG handling could permit unauthorized zone transfers
    or zone updates. These flaws are disclosed in CVE-2017-3142 and
    CVE-2017-3143.
  * The BIND installer on Windows used an unquoted service path, which
    can enable privilege escalation. This flaw is disclosed in
    CVE-2017-3141.
  * With certain RPZ configurations, a response with TTL 0 could cause
    named to go into an infinite query loop. This flaw is disclosed in
    CVE-2017-3140.
  * Addresses could be referenced after being freed during resolver
    processing, causing an assertion failure. The chances of this
    happening were remote, but the introduction of a delay in
    resolution increased them. This bug is disclosed in CVE-2017-3145.

At least one of libjson|libxml2 is required for bind
statistics to function.

Selecting libjson|libxml2 will result in an additional
dependency required to build and install bind-libs.
