Title:
  libgnutls30 3.4.10 segfaults with knot-resolver 2.3

Status in gnutls28 package in Ubuntu:
  Confirmed

Bug description:
  Activating DNS over TLS in knot-resolver 2.3.0-1 with Ubuntu 16.04
  (Xenial) and libgnutls 3.4.10 results in segmentation fault (double
  free).

  Upstream bug in Knot-resolver is filled here
  (https://gitlab.labs.nic.cz/knot/knot-resolver/issues/365). Discussion
  with developers lead us to bug in gnutls, which was patched in version
  3.5.5 (https://gitlab.com/gnutls/gnutls/blob/gnutls_3_6_2/NEWS#L413).

  Test with same configuration on Ubuntu 18 (Bionic), where version of
  libgnutls30:amd64 is 3.5.18-1ubuntu1 works good.

  Please consider update to newer minor version of GNUTLS.
