{"id":"ALPINE-CVE-2020-25829","details":"An issue has been found in PowerDNS Recursor before 4.1.18, 4.2.x before 4.2.5, and 4.3.x before 4.3.5. A remote attacker can cause the cached records for a given name to be updated to the Bogus DNSSEC validation state, instead of their actual DNSSEC Secure state, via a DNS ANY query. This results in a denial of service for installation that always validate (dnssec=validate), and for clients requesting validation when on-demand validation is enabled (dnssec=process).","modified":"2026-11-03T06:32:24.766002148Z","published":"2020-10-16T06:15:12.357Z","upstream":["CVE-2020-25829"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-25829"}],"affected":[{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}},{"package":{"name":"pdns-recursor","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/pdns-recursor?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25829.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
