{"id":"CVE-2020-11080","details":"In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., \u003e 32), then drop the connection.","aliases":["BIT-node-2020-11080","BIT-node-min-2020-11080","GHSA-q5wr-xfw9-q7xr"],"modified":"2026-05-13T13:50:54.148028Z","published":"2020-06-03T23:15:11.073Z","related":["ALSA-2020:2755","ALSA-2020:2848","ALSA-2020:2852","CGA-78xc-93mc-j6fw","SUSE-SU-2020:1568-1","SUSE-SU-2020:1575-1","SUSE-SU-2020:1576-1","SUSE-SU-2020:1606-1","SUSE-SU-2020:2800-1","SUSE-SU-2021:0930-1","SUSE-SU-2021:0931-1","SUSE-SU-2021:0932-1","openSUSE-SU-2020:0802-1","openSUSE-SU-2021:0468-1","openSUSE-SU-2024:11091-1","openSUSE-SU-2024:11096-1"],"database_specific":{"unresolved_ranges":[{"source":"CPE_FIELD","extracted_events":[{"introduced":"10.0.0"},{"last_affected":"10.12.0"},{"introduced":"12.0.0"},{"last_affected":"12.12.0"},{"introduced":"14.0.0"},{"last_affected":"14.4.0"}],"cpe":"cpe:2.3:a:nodejs:node.js:*:*:*:*:-:*:*:*"},{"source":"CPE_FIELD","extracted_events":[{"introduced":"10.13.0"},{"fixed":"10.21.0"},{"introduced":"12.13.0"},{"fixed":"12.18.0"}],"cpe":"cpe:2.3:a:nodejs:node.js:*:*:*:*:lts:*:*:*"},{"source":"CPE_FIELD","extracted_events":[{"last_affected":"14.3.0"}],"cpe":"cpe:2.3:a:oracle:banking_extensibility_workbench:14.3.0:*:*:*:*:*:*:*"},{"source":"CPE_FIELD","extracted_events":[{"last_affected":"14.4.0"}],"cpe":"cpe:2.3:a:oracle:banking_extensibility_workbench:14.4.0:*:*:*:*:*:*:*"},{"source":"CPE_FIELD","extracted_events":[{"fixed":"21.1.2"}],"cpe":"cpe:2.3:a:oracle:blockchain_platform:*:*:*:*:*:*:*:*"},{"source":"CPE_FIELD","extracted_events":[{"last_affected":"3.1.0"}],"cpe":"cpe:2.3:a:oracle:enterprise_communications_broker:3.1.0:*:*:*:*:*:*:*"},{"source":"CPE_FIELD","extracted_events":[{"last_affected":"3.2.0"}],"cpe":"cpe:2.3:a:oracle:enterprise_communications_broker:3.2.0:*:*:*:*:*:*:*"},{"source":"CPE_FIELD","extracted_events":[{"last_affected":"10.0"}],"cpe":"cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*"},{"source":"CPE_FIELD","extracted_events":[{"last_affected":"31"}],"cpe":"cpe:2.3:o:fedoraproject:fedora:31:*:*:*:*:*:*:*"},{"source":"CPE_FIELD","extracted_events":[{"last_affected":"33"}],"cpe":"cpe:2.3:o:fedoraproject:fedora:33:*:*:*:*:*:*:*"},{"source":"CPE_FIELD","extracted_events":[{"last_affected":"15.1"}],"cpe":"cpe:2.3:o:opensuse:leap:15.1:*:*:*:*:*:*:*"}]},"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/10/msg00023.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4OOYAMJVLLCLXDTHW3V5UXNULZBBK4O6/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AAC2AA36OTRHKSVM5OV7TTVB3CZIGEFL/"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00024.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2021/10/msg00011.html"},{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4696"},{"type":"ADVISORY","url":"https://www.oracle.com//security-alerts/cpujul2021.html"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpujan2021.html"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpujul2020.html"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpuoct2020.html"},{"type":"FIX","url":"https://github.com/nghttp2/nghttp2/commit/336a98feb0d56b9ac54e12736b18785c27f75090"},{"type":"FIX","url":"https://github.com/nghttp2/nghttp2/commit/f8da73bd042f810f34d19f9eae02b46d870af394"},{"type":"FIX","url":"https://github.com/nghttp2/nghttp2/security/advisories/GHSA-q5wr-xfw9-q7xr"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuapr2022.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/graalvm/graalvm-ce-builds","events":[{"introduced":"0"},{"last_affected":"6c1e8e199e171761b388b0f15afadfba0b552abc"},{"last_affected":"1ebb60f5d73c0a82424003ee6ff22fb7bf163efe"}],"database_specific":{"source":"CPE_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"19.3.2"},{"last_affected":"20.1.0"}],"cpe":["cpe:2.3:a:oracle:graalvm:19.3.2:*:*:*:enterprise:*:*:*","cpe:2.3:a:oracle:graalvm:20.1.0:*:*:*:enterprise:*:*:*"]}}],"versions":["vm-19.3.2","vm-19.3.2-pre","vm-20.0.1","vm-20.1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2020-11080.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/mysql/mysql-server","events":[{"introduced":"0"},{"last_affected":"527c12ed611f3fe072c3043734319edb2c733099"},{"last_affected":"a7ea56eadbd58091cfd509e98b735f5c48aace8e"},{"last_affected":"e110bb0b6ff8f35fed600855fc2609a15ef08069"},{"last_affected":"b0060f1faabb0593a9b566a97ac71acf615b003b"},{"introduced":"ae41ce7c4ecff5e1e336ab768867370b8c94e02d"},{"last_affected":"6acd2e9068e1652d9a987a6a89769ee108cbe883"},{"introduced":"270fd3411e3d671a73ed9725940a30080f59ce6d"},{"last_affected":"f8cdce86448a211511e8a039c62580ae16cb96f5"}],"database_specific":{"source":"CPE_FIELD","extracted_events":[{"introduced":"0"},{"last_a
