  "details" : [ "c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 length as a graceful shutdown of the connection. This issue has been patched in version 1.19.1.", "A vulnerability was found in c-ares. This issue occurs due to a 0-byte UDP payload that can cause a Denial of Service." ],
