Debian Security Advisory 5620-1
Debian Linux Security Advisory 5620-1 - Two vulnerabilities were discovered in unbound, a validating, recursive, caching DNS resolver. Specially crafted DNSSEC answers could lead unbound down a very CPU intensive and time costly DNSSEC (CVE-2023-50387) or NSEC3 hash (CVE-2023-50868) validation path, resulting in denial of service.
