Package        : unbound
CVE ID         : CVE-2023-50387 CVE-2023-50868
Debian Bug     : 1063845
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.
