CVE-2018-14644 (GCVE-0-2018-14644)

Vulnerability from cvelistv5 – Published: 2018-11-09 19:00 – Updated: 2024-08-05 09:38
VLAI?
Summary
An issue has been found in PowerDNS Recursor from 4.0.0 up to and including 4.1.4. 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.
