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.
