Researchers recently found a vulnerability in the way DNS resolvers handle DNSSEC validation that allow attackers to DoS resolvers with a single DNS request

https://www.theregister.com/2024/02/13/dnssec_vulnerability_internet/

It is highly recommended to upgrade your resolvers to the following versions:

unbound: 1.91.1
PiHole: FTL 5.25 or Docker 2024.02.0
Bind9: 9.19.17
dnsmasq: 2.90
and probably any other resolver you use
