CVE-2024-33655

CVE-2024-33655 affects Unbound, a validating, recursive DNS resolver. Documented details describe DNSBomb: remote attackers can trigger denial of service by accumulating DNS queries so responses burst later, potentially enabling amplification. Multiple advisories reference mitigation via updating...

CVE-2024-33655

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...
