@gjacobse the article is a little misleading. Linux doesn't provide DNS services. So Linux can't be the issue. Any given Linux distro might have one or more default DNS server options, so Ubuntu or RHEL might have this issue, but Linux itself cannot.

In the article, you have to dig before they mention BIND, a DNS server, as being a problem with this issue. BIND is certainly the de facto standard on Linux and represents a problem for the community and ecosystem, but the article presents it in very much a click bait sort of way.

And then it appears to describe the issue as a protocol issue, not an implementation issue and seems to feel that the issue is just that the protocol used for DNS was insecure.
