- Time-of-check Time-of-use (TOCTOU) Race Condition
Summary
If the auth responds very slowly and the records expire in between, the capping of TTLs is not enforced for lack of data. This does not happen on regular resolve as then then the
child records are used immediately if not expired and thus valid, or the
records are expired, and in that case not used. So this case
can only happen if almost expired records are used to refresh the
authoritative NS records.

CWE
- CWE-345 - Insufficient Verification of Data Authenticity
Summary
An attacker spoofing answers to ECS enabled requests sent out by the Recursor has a chance of success higher than non-ECS enabled queries.
The updated version include various mitigations against spoofing attempts of ECS enabled queries by chaining ECS enabled requests and enforcing stricter validation of the received answers.
The most strict mitigation done when the new setting outgoing.edns_subnet_harden (old style name edns-subnet-harden) is enabled.

Summary
An attacker can publish a zone containing specific Resource Record Sets. Processing and caching results for these sets can lead to an illegal memory accesses and crash of the Recursor, causing a denial of service.
The remedy is: upgrade to the patched 5.2.1 version.
