nodejs: Denial of Service by resource exhaustion CWE-400 due to unfinished HTTP/1.1 requests
Node.js < 14.11.0 is vulnerable to HTTP denial of service (DoS) attacks based on delayed requests submission which can make the server unable to accept new connections.
A flaw was found in Node.js 14.x, in versions before 14.11, where it is vulnerable to a denial of service caused by delayed requests. When used as an edge server, this flaw allows an attacker to initiate a large number of HTTP requests, causing resource exhaustion and leaving the service unable to accept new connections. The highest threat from this vulnerability is to system availability.
Statement: NodeJS is included in Red Hat Quay as a dependency of Yarn which is only used while building Red Hat Quay, and not during runtime.

CVE-2020-8251 [HIGH] CVE-2020-8251 nodejs: Denial of Service by resource exhaustion CWE-400 due to unfinished HTTP/1.1 requests
CVE-2020-8251 nodejs: Denial of Service by resource exhaustion CWE-400 due to unfinished HTTP/1.1 requests
Node.js 14.x versions prior to 14.11 are vulnerable to a denial of service condition based on delayed requests. When used as an edge server, an attacker can initiate but not complete a large number of HTTP requests causing resource exhaustion and rendering the server unable to accept new connections.
In 14.11 a new option "http.Server.requestTimeout" is introduced to mitigate this vulnerability.
