unbound resolver

The unbound resolver tag covers discussions about NLnet Labs' Unbound DNS resolver, particularly in the context of security vulnerabilities and operational impact on Windows and enterprise IT infrastructure. A recent thread highlights CVE-2026-42923, a degradation-of-service flaw where DNSSEC NSEC3 hash loops can reduce resolver availability. This bug is not a typical Windows vulnerability but an infrastructure weakness that affects DNS performance. The tag focuses on how such issues degrade service reliability, the importance of patching, and the broader implications for network administrators managing DNS security and availability.
