CVE-2024-25581 · Transfer requests received over DoH can lead to a denial of service in DNSdist
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
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.
