Hi, The following vulnerability was published for dnsjava. CVE-2023-50387[0]: | Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, | 6840, and related RFCs) allow remote attackers to cause a denial of | service (CPU consumption) via one or more DNSSEC responses, aka the | "KeyTrap" issue. One of the concerns is that, when there is a zone | with many DNSKEY and RRSIG records, the protocol specification | implies that an algorithm must evaluate all combinations of DNSKEY | and RRSIG records. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
