The vulnerability was patched by Alex Peshkov.
The use case for wanting a CNAME at a zone apex is typically one where an organization would like to Isc case 1 their web content hosted and provisioned by a specialist third party. Some third parties, rather than giving you an IP address for the hosting provisioning in which case, they would most likely be using anycast behind the scenes will instead give you a new target name to which they ask you to alias your webserver name in your DNS zone.
What is the zone apex?
They are DNS records whose name are the same as the zone itself. For example in in zone mydomainname. If a CNAME RR is present at a node, no other data should be present; this ensures that the data for a canonical name and its aliases cannot be different. The resolver then adds both answers for www.
MX that serves as the service identifier. This is because its meaning and interpretation was strictly defined in the DNS protocol; all current DNS client and server implementations adhere to this specification.
Webserver redirection — set up a webserver for mydomainname. This is a very simple solution, and one which leaves the final provisioning in the hands of the web hosting provider. This is a fairly simple workaround to implement. You will have to monitor and regularly update those records although this is something that could be scripted.
This is a very simple workaround to implement Cons: This will not work for an organization who has many more names in their DNS zone. You also cannot implement this as a solution if the domain is also used for mail.
These records are never returned directly to clients. This is a simple solution to the problem for administrators Cons: In addition, the need to perform DNS recursion prior to synthesizing the query response for the client increases the query response time, as well as adding the potential for authoritative server problems to be introduced if the necessary recursive resolution encounters delays or problems.
Authoritative DNS servers, particularly those that are public-facing, do not normally perform any recursive functions. This is a very simple solution that scales well if your web hosting provider is using anycast provisioning.
If your chosen web hosting provider does not offer this option, then it will not be available to you without changing to another web hosting provider. · This article assumes that you are familiar with DNSSEC.
