| Doc Text: |
A flaw was found in hickory-dns. An attacker can cause a Denial of Service (DoS) by supplying an untrusted DNS zone file containing malformed Service Binding (SVCB) or HTTPS records where an isolated quotation mark replaces an expected parameter value. Processing this malformed input triggers an unhandled crash in the parser, halting the DNS service.
