Hi, The following vulnerability was published for rust-hickory-proto. CVE-2025-25188[0]: | Hickory DNS is a Rust based DNS client, server, and resolver. A | vulnerability present starting in version 0.8.0 and prior to | versions 0.24.3 and 0.25.0-alpha.5 impacts Hickory DNS users relying | on DNSSEC verification in the client library, stub resolver, or | recursive resolver. The DNSSEC validation routines treat entire | RRsets of DNSKEY records as trusted once they have established trust | in only one of the DNSKEYs. As a result, if a zone includes a DNSKEY | with a public key that matches a configured trust anchor, all keys | in that zone will be trusted to authenticate other records in the | zone. There is a second variant of this vulnerability involving DS | records, where an authenticated DS record covering one DNSKEY leads | to trust in signatures made by an unrelated DNSKEY in the same zone. | Versions 0.24.3 and 0.25.0-alpha.5 fix the issue. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
