{"id":"BIT-node-2024-27983","details":"An attacker can make the Node.js HTTP/2 server completely unavailable by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client triggering the Http2Session destructor while header frames are still being processed (and stored in memory) causing a race condition.","aliases":["BIT-node-min-2024-27983","CVE-2024-27983"],"modified":"2026-03-11T07:48:49.016072Z","published":"2024-06-04T09:49:21.510Z","database_specific":{"cpes":["cpe:2.3:a:nodejs:node.js:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/04/03/16"},{"type":"WEB","url":"https://hackerone.com/reports/2319584"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/JDECX4BYZLMM4S4LALN4DPZ2HUTTPLKE/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/YDVFUH7ACZPYB3BS4SVILNOY7NQU73VW/"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20240510-0002/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-27983"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/09/msg00029.html"},{"type":"WEB","url":"https://www.kb.cert.org/vuls/id/421644"},{"type":"WEB","url":"https://github.com/nodejs/node/releases/tag/v18.20.1"},{"type":"WEB","url":"https://github.com/nodejs/node/releases/tag/v20.12.1"},{"type":"WEB","url":"https://github.com/nodejs/node/releases/tag/v21.7.2"}],"affected":[{"package":{"name":"node","ecosystem":"Bitnami","purl":"pkg:bitnami/node"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"18.20.1"},{"introduced":"19.0.0"},{"fixed":"20.12.1"},{"introduced":"21.0.0"},{"fixed":"21.7.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/node/BIT-node-2024-27983.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H"}]}],"schema_version":"1.7.5"}
