{"id":"UBUNTU-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":"2026-05-20T16:17:34.225507530Z","published":"2024-06-17T20:15:00Z","upstream":["CVE-2024-37890"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-37890"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-37890"},{"type":"REPORT","url":"https://github.com/websockets/ws/security/advisories/GHSA-3h5v-q93c-6h6q"},{"type":"REPORT","url":"https://github.com/websockets/ws/issues/2230"},{"type":"REPORT","url":"https://github.com/websockets/ws/pull/2231"},{"type":"REPORT","url":"https://github.com/websockets/ws/commit/e55e5106f10fcbaac37cfa89759e4cc0d073a52c"},{"type":"REPORT","url":"https://github.com/websockets/ws/commit/22c28763234aa75a7e1b76f5c01c181260d7917f"},{"type":"REPORT","url":"https://github.com/websockets/ws/commit/eeb76d313e2a00dd5247ca3597bba7877d064a63"},{"type":"REPORT","url":"https://github.com/websockets/ws/commit/4abd8f6de4b0b65ef80b3ff081989479ed93377e"},{"type":"REPORT","url":"https://github.com/websockets/ws/commit/22c28763234aa75a7e1b76f5c01c181260d7917f"},{"type":"REPORT","url":"https://github.com/websockets/ws/commit/4abd8f6de4b0b65ef80b3ff081989479ed93377e"},{"type":"REPORT","url":"https://github.com/websockets/ws/commit/e55e5106f10fcbaac37cfa89759e4cc0d073a52c"},{"type":"REPORT","url":"https://github.com/websockets/ws/commit/eeb76d313e2a00dd5247ca3597bba7877d064a63"},{"type":"REPORT","url":"https://nodejs.org/api/http.html#servermaxheaderscount"}],"affected":[{"package":{"name":"node-ws","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/node-ws?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.7.2+ds1.349b7460-1","1.0.1+ds1.e6ddaae4-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-ws","binary_version":"1.0.1+ds1.e6ddaae4-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-37890.json"}},{"package":{"name":"node-ws","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/node-ws?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.0+ds1.e6ddaae4-3build1","1.1.0+ds1.e6ddaae4-3ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-ws","binary_version":"1.1.0+ds1.e6ddaae4-3ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-37890.json"}},{"package":{"name":"node-ws","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-ws?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.0+ds1.e6ddaae4-5","7.2.1-2","7.2.1-3"],"ecosystem_specific":{"binaries":[{"binary_name":"node-ws","binary_version":"7.2.1-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-37890.json"}},{"package":{"name":"node-ws","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-ws?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.4.2+~cs18.0.8-2","7.5.5+~cs13.0.13-1","8.5.0+~cs13.3.3-2"],"ecosystem_specific":{"binaries":[{"binary_name":"node-ws","binary_version":"8.5.0+~cs13.3.3-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-37890.json"}},{"package":{"name":"node-ws","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-ws?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.11.0+~cs13.7.3-1","8.11.0+~cs13.7.3-2"],"ecosystem_specific":{"binaries":[{"binary_name":"node-ws","binary_version":"8.11.0+~cs13.7.3-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-37890.json"}},{"package":{"name":"node-ws","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/node-ws?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.18.0+~cs14.5.15-1","8.18.1+~cs14.18.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-ws","binary_version":"8.18.1+~cs14.18.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-37890.json"}},{"package":{"name":"node-ws","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-ws?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.18.1+~cs14.18.2-1","8.19.0+~cs14.19.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-ws","binary_version":"8.19.0+~cs14.19.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-37890.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
