{"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"],"modified":"2026-04-16T04:37:15.762855914Z","published":"2020-06-03T23:15:11.073Z","related":["ALSA-2020:2755","ALSA-2020:2848","ALSA-2020:2852","CGA-78xc-93mc-j6fw","GHSA-q5wr-xfw9-q7xr","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"],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4OOYAMJVLLCLXDTHW3V5UXNULZBBK4O6/"},{"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/AAC2AA36OTRHKSVM5OV7TTVB3CZIGEFL/"},{"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":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00024.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuapr2022.html"},{"type":"FIX","url":"https://github.com/nghttp2/nghttp2/commit/f8da73bd042f810f34d19f9eae02b46d870af394"},{"type":"FIX","url":"https://github.com/nghttp2/nghttp2/commit/336a98feb0d56b9ac54e12736b18785c27f75090"},{"type":"FIX","url":"https://github.com/nghttp2/nghttp2/security/advisories/GHSA-q5wr-xfw9-q7xr"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/graalvm/graalvm-ce-builds","events":[{"introduced":"0"},{"last_affected":"6c1e8e199e171761b388b0f15afadfba0b552abc"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"19.3.2"}]}},{"type":"GIT","repo":"https://github.com/mysql/mysql-server","events":[{"introduced":"0"},{"last_affected":"a7ea56eadbd58091cfd509e98b735f5c48aace8e"},{"introduced":"0"},{"last_affected":"e110bb0b6ff8f35fed600855fc2609a15ef08069"},{"introduced":"ae41ce7c4ecff5e1e336ab768867370b8c94e02d"},{"last_affected":"6acd2e9068e1652d9a987a6a89769ee108cbe883"},{"introduced":"0"},{"last_affected":"b0060f1faabb0593a9b566a97ac71acf615b003b"},{"introduced":"270fd3411e3d671a73ed9725940a30080f59ce6d"},{"last_affected":"f8cdce86448a211511e8a039c62580ae16cb96f5"}],"database_specific":{"versions":[{"introduced":"7.3.0"},{"last_affected":"7.3.30"},{"introduced":"7.4.0"},{"last_affected":"7.4.29"},{"introduced":"7.5.0"},{"last_affected":"7.5.19"},{"introduced":"7.6.0"},{"last_affected":"7.6.15"},{"introduced":"8.0.0"},{"last_affected":"8.0.21"}]}},{"type":"GIT","repo":"https://github.com/nghttp2/nghttp2","events":[{"introduced":"0"},{"fixed":"336a98feb0d56b9ac54e12736b18785c27f75090"},{"fixed":"f8da73bd042f810f34d19f9eae02b46d870af394"}]},{"type":"GIT","repo":"https://github.com/nodejs/node","events":[{"introduced":"0"},{"last_affected":"fa9990f3fb5b06fe94e294925246d2c136deb2c2"},{"introduced":"0"},{"last_affected":"cf41627411886000429bde058a6594fb7f6d6d47"},{"introduced":"0"},{"last_affected":"2291e079f22e6df1f7683a05d17364b2ab3bfdab"},{"introduced":"0"},{"last_affected":"5d81e4d677e8a00c2d0d3a23e2bd74bf9f1deb57"},{"introduced":"0"},{"last_affected":"27adbf027f2dd3a75b22518f6825e1a1937059d1"},{"introduced":"0"},{"last_affected":"53596fd2454fda431a4b2b578760cbab3729c374"},{"introduced":"0"},{"last_affected":"236455303fee234478381431bf112ddc966bb537"},{"introduced":"0"},{"last_affected":"68ef4a687d5a1802b9f585d7f464c44ce6caa766"},{"introduced":"cf41627411886000429bde058a6594fb7f6d6d47"},{"last_affected":"4a276cc2a960b3f9a138ac3a99c9249a63b4d472"},{"introduced":"ab4af087e83d91a46354d765306d3543b1d85423"},{"fixed":"23adb548a57db0c56e359265108e7fe71d8b4f73"},{"introduced":"2f45ad8060e13d5ac912335096d21526f2f9602b"},{"last_affected":"921493e2287aa895679620155b5288b2e1587bfd"},{"introduced":"42cce5a9d0fd905bf4ad7a2528c36572dfb8b5ad"},{"fixed":"f19f5b34d7c4e9a4e339b40bc791c78469091704"},{"introduced":"73aa21658dfa6a22c06451d080152b32b1f98dbe"},{"last_affected":"27adbf027f2dd3a75b22518f6825e1a1937059d1"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"9.0"},{"introduced":"0"},{"last_affected":"10.0"},{"introduced":"0"},{"last_affected":"15.1"},{"introduced":"0"},{"last_affected":"14.3.0"},{"introduced":"0"},{"last_affected":"14.4.0"},{"introduced":"0"},{"last_affected":"3.1.0"},{"introduced":"0"},{"last_affected":"3.2.0"},{"introduced":"0"},{"last_affected":"20.1.0"},{"introduced":"10.0.0"},{"last_affected":"10.12.0"},{"introduced":"10.13.0"},{"
