CVE-2018-14644 - log back

CVE-2018-14644 created at 25 Sep 2019 19:31:40
Severity	+ Medium
Remote	+ Remote
Type	+ Denial of service
Description	+ An issue has been found in PowerDNS Recursor before 4.1.5 where a remote attacker sending a DNS query for a meta-type like OPT can lead to a zone being wrongly cached as failing DNSSEC validation. It only arises if the parent zone is signed, and all the authoritative servers for that parent zone answer with FORMERR to a query for at least one of the meta-types. As a result, subsequent queries from clients requesting DNSSEC validation will be answered with a ServFail.
