Package        : knot-resolver
Version        : 3.2.1-3+deb10u1
CVE ID         : CVE-2022-40188

It was discovered that there was a potential remote denial-of-service
vulnerability in the knot-resolver DNSSEC-validating DNS resolver.

Remote attackers could have caused a denial of service via CPU
consumption by exploiting algorithmic complexity: during an attack,
an authoritative server would return large nameserver or address
sets.

For Debian 10 buster, this problem has been fixed in version
3.2.1-3+deb10u1.

We recommend that you upgrade your knot-resolver packages.
