{"id":"ALPINE-CVE-2024-25581","details":"When incoming DNS over HTTPS support is enabled using the nghttp2 provider, and queries are routed to a tcp-only or DNS over TLS backend, an attacker can trigger an assertion failure in DNSdist by sending a request for a zone transfer (AXFR or IXFR) over DNS over HTTPS, causing the process to stop and thus leading to a Denial of Service. DNS over HTTPS is not enabled by default, and backends are using plain DNS (Do53) by default.","modified":"2026-11-03T06:32:49.495455851Z","published":"2024-05-14T15:05:29.707Z","upstream":["CVE-2024-25581"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2024-25581"}],"affected":[{"package":{"name":"dnsdist","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/dnsdist?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-25581.json"}},{"package":{"name":"dnsdist","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/dnsdist?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-25581.json"}},{"package":{"name":"dnsdist","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/dnsdist?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-25581.json"}},{"package":{"name":"dnsdist","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/dnsdist?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-25581.json"}},{"package":{"name":"dnsdist","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/dnsdist?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-25581.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"}]}
