This allows an attacker in position of man-in-the-middle to alter the content of records by issuing a valid signature for the crafted records.","published":"2018-01-23T15:29:00.000Z","lastModified":"2026-06-17T01:07:14.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.0","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-347"],"affected":["powerdns/recursor"],"epss":{"score":0.00709,"percentile":0.53312,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.71%).
