{"id":"UBUNTU-CVE-2024-33655","details":"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.","modified":"2026-06-02T20:15:06.978619574Z","published":"2024-05-10T00:00:00Z","related":["USN-6791-1"],"upstream":["CVE-2024-33655"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-33655"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-33655"},{"type":"REPORT","url":"https://nlnetlabs.nl/downloads/unbound/CVE-2024-33655.txt"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6791-1"}],"affected":[{"package":{"name":"unbound","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/unbound?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.20-1","1.4.21-1","1.4.21-1ubuntu1","1.4.21-1ubuntu2","1.4.22-1ubuntu1","1.4.22-1ubuntu2","1.4.22-1ubuntu3","1.4.22-1ubuntu4","1.4.22-1ubuntu4.14.04.1","1.4.22-1ubuntu4.14.04.2","1.4.22-1ubuntu4.14.04.3","1.4.22-1ubuntu4.14.04.3+esm1","1.4.22-1ubuntu4.14.04.3+esm2","1.4.22-1ubuntu4.14.04.3+esm3"],"ecosystem_specific":{"priority_reason":"Upstream
