{"id":"DEBIAN-CVE-2024-37890","details":"ws is an open source WebSocket client and server for Node.js. A request with a number of headers exceeding theserver.maxHeadersCount threshold could be used to crash a ws server. The vulnerability was fixed in ws@8.17.1 (e55e510) and backported to ws@7.5.10 (22c2876), ws@6.2.3 (eeb76d3), and ws@5.2.4 (4abd8f6). In vulnerable versions of ws, the issue can be mitigated in the following ways: 1. Reduce the maximum allowed length of the request headers using the --max-http-header-size=size and/or the maxHeaderSize options so that no more headers than the server.maxHeadersCount limit can be sent. 2. Set server.maxHeadersCount to 0 so that no limit is applied.","modified":"2026-09-15T09:03:06.890293551Z","published":"2024-06-17T20:15:13.203Z","upstream":["CVE-2024-37890"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-37890"}],"affected":[{"package":{"name":"node-ws","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-ws?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.11.0+~cs13.7.3-1","8.11.0+~cs13.7.3-2","8.18.0+~cs13.7.11-1","8.18.0+~cs14.5.15-1","8.18.1+~cs14.18.2-1","8.19.0+~cs14.19.1-1","8.20.1+~cs14.19.1-1","8.21.0+~cs14.19.1-1","8.21.1+~cs14.19.1-1","8.21.3+~cs14.19.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-37890.json"}},{"package":{"name":"node-ws","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-ws?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.18.0+~cs13.7.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-37890.json"}},{"package":{"name":"node-ws","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-ws?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.18.0+~cs13.7.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-37890.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
