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
What about on mobile? Those of us who use dns filtering on mobile.
I’m not familiar with off-the-shelf DNS filtering on mobile, but since running a DNS resolver on-device would be impractical, I think they must be using a DNS server that they maintain. Which means that unless I’m wrong, the vulnerability lies on their end, you should be fine.
I been using rethink dns but ik their are other for android at least. Works by making a local vpn magic.
They maintain their own resolver, so they have to patch it if not done already.
