CVE-2024-25581
Transfer requests received over DoH can lead to a denial of service in DNSdist
Summary
Transfer requests received over DoH can lead to a denial of service in DNSdist
Original description
The description as published by the source.
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.
