high Tenable Cloud Security Plugin ID 426433
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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. (CVE-2024-25581)
