| Doc Text: |
A flaw was found in hickory-proto. This vulnerability allows an attacker to cause a Denial of Service (DoS) by providing untrusted DNS zone files with malformed Application-Layer Protocol Negotiation (ALPN) values. Inadequate validation in the Service Binding (SVCB) and HTTPS record presentation format parser causes an unhandled panic, crashing the parsing process when encountering improperly formatted input.
