Descriptions

A vulnerability was discovered in DNS resolver component of knot resolver through version 3.2.0 before 4.1.0 which allows remote attackers to bypass DNSSEC validation for non-existence answer. NXDOMAIN answer would get passed through to the client even if its DNSSEC validation failed, instead of sending a SERVFAIL packet. Caching is not affected by this particular bug but see CVE-2019-10191.

Se detectó una vulnerabilidad en el componente de resolución de DNS de knot resolver hasta la versión 3.2.0 anterior a 4.1.0, que permite a los atacantes remotos omitir la comprobación DNSSEC para una respuesta de no existencia. La respuesta NXDOMAIN se pasaría hacia el cliente incluso si fallara la comprobación DNSSEC, en lugar de enviar un paquete SERVFAIL. El almacenamiento en caché no está afectado por este bug en particular, pero consulte el CVE-2019-10191.
