  "summary": "CVE-2019-5737 is fixed in 7 products on 2 platforms, first by Node.js 6 6.17.0, released February 28, 2019. 1 other affected product has no fix yet. It is not reported as exploited. Patch Radar priority: High.",
  "title": "Node.js 6 and 1 other: Uncontrolled Resource Consumption / Denial of Service",
  "description": "In Node.js including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1, an attacker can cause a Denial of Service (DoS) by establishing an HTTP or HTTPS connection in keep-alive mode and by sending headers very slowly. This keeps the connection and associated resources alive for a long period of time. Potential attacks are mitigated by the use of a load balancer or other proxy layer. This vulnerability is an extension of CVE-2018-12121, addressed in November and impacts all active Node.js release lines including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1.",
