Astra Linux – Vulnerability in c-ares

c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service attacks. When a target resolver sends a query, the attacker creates a malformed UDP packet with a length of 0 and sends it back to the target resolver. The target resolver misinterprets this 0-length field as an...
