Last modified

CVE-2024-33655 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The DNS protocol in RFC 1035 and updates allows remote attackers to cause a denial of service (resource consumption) by arranging for DNS queries to be accumulated for seconds, such that responses are later sent in a pulsing burst (which can be considered traffic amplification in some cases), aka the "DNSBomb" issue.. EPSS estimates a 1.73% chance of exploitation in the next 30 days.
