Overview
Affected versions of this package are vulnerable to Origin Validation Error in the DNSSEC validation process when the Next Domain Name field in NSEC records points outside the signer's zone. An attacker can bypass DNSSEC validation by crafting malicious NSEC records that are accepted as valid, potentially allowing unauthorized domain responses to be trusted.
