{"schemaVersion":3,"id":"CVE-2018-6977","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"VMware ESXi (6.7, 6.5, 6.0), Workstation (15.x and 14.x) and Fusion (11.x and 10.x) contain a denial-of-service vulnerability due to an infinite loop in a 3D-rendering shader. Successfully exploiting this issue may allow an attacker with normal user privileges in the guest to make the VM unresponsive, and in some cases, possibly result other VMs on the host or the host itself becoming unresponsive.","dates":{"published":"2018-10-09T20:00:00.000Z","modified":"2024-09-16T20:26:19.691Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.0","versionLabel":"v3.0","source":"NVD","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":4.9,"severity":"medium","vector":"AV:L/AC:L/Au:N/C:N/I:N/A:C","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00426,"percentile":0.35517,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.00426},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00463,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00426,"percentile":0.35517}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00463,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00426,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00426,"percent
