Package : unbound
Version : 1.9.0-2+deb10u4
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.

For Debian 10 buster, these problems have been fixed in version
1.9.0-2+deb10u4.

We recommend that you upgrade your unbound packages.
