before 4.3.20 allows remote attackers to cause a denial of service via (1) non-ASCII characters in a reverse DNS lookup result from a Received header, which leads to a Receiver service stop, and (2) unspecified vectors involving malformed messages, which causes \"unpredictable behavior\" that prevents the Security service from processing more messages.","dates":{"published":"2006-06-24T01:00:00.000Z","modified":"2024-08-07T18:23:21.175Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5,"severity":"medium","version":"2.0","versionLabel":"v2.0","source":"NVD","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","computed":false,"selection":"backend-summary"},"metrics":[{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":5,"severity":"medium","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.01856,"percentile":0.78878,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.01856},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.01856,"percentile":0.78878}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01856,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01856,"percentile":null},{
