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." } ] }, "impact": { "cvss": [ [ { "vectorString": "5.3/CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L", "version": "3.0" } ] ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-20" } ] } ] }, "references": { "reference_data": [ { "name": "https://docs.powerdns.com/recursor/security-advisories/powerdns-advisory-2018-07.html", "refsource": "CONFIRM", "url": "https://docs.powerdns.com/recursor/security-advisories/powerdns-advisory-2018-07.html" }, { "name": "https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14644", "refsource": "CONFIRM", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14644" } ] } }
