A vulnerability was discovered in DNS resolver component of knot resolver
through version 3.2.0 before 4.1.0 which allows remote attackers to bypass
DNSSEC validation for non-existence answer. NXDOMAIN answer would get
passed through to the client even if its DNSSEC validation failed, instead
of sending a SERVFAIL packet. Caching is not affected by this particular
bug but see CVE-2019-10191.
