A frequent question was: "Which package contained the 'dig' utility?" This
change should make the question answerable through 'guix search'.
* gnu/packages/dns.scm (isc-bind)[synopsis]: Remove leading article.
[description]: Add a table listing the utilities contained in the 'utils'
output and insert a missing space between two sentences.
[home-page]: Update.
This fixes CVE-2020-6071, CVE-2020-6072, CVE-2020-6073, CVE-2020-6077,
CVE-2020-6078, and CVE-2020-6079.
* gnu/packages/dns.scm (libmicrodns): Update to 0.1.2.
[source]: Build from a tarball.
[build-system]: Use the meson-build-system.
[native-inputs]: Remove field.
* gnu/packages/dns.scm (ddclient): Update to 3.9.1.
[source]: Use GIT-FETCH and add a FILE-NAME.
[native-inputs]: Remove gzip and tar.
[arguments]: Adapt to git checkout source.
The Guix unbound package is not vulnerable in its default configuration,
because we do not build with ‘--enable-ipsecmod’.
* gnu/packages/dns.scm (unbound): Update to 1.9.5.
