Overview

Affected versions of this package are vulnerable to Information Exposure due to re-using of the DNS transaction id (TXID) value from client queries, which allows attackers (able to send queries to the resolver) to conduct DNS cache-poisoning attacks since the TXID value is known to the attacker.
