{"schemaVersion":3,"id":"CVE-2017-6166","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"In BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Link Controller, PEM, and WebSafe software 12.0.0 to 12.1.1, in some cases the Traffic Management Microkernel (TMM) may crash when processing fragmented packets. This vulnerability affects TMM through a virtual server configured with a FastL4 profile. Traffic processing is disrupted while TMM restarts. If the affected BIG-IP system is configured as part of a device group, it will trigger a failover to the peer device.","dates":{"published":"2017-11-22T16:00:00.000Z","modified":"2024-09-16T19:36:14.016Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.9,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.9,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":4.3,"severity":"medium","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.01928,"percentile":0.79673,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.01928},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.01928,"percentile":0.79673}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01928,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01928,"percentile":n
