Created nodejs-tough-cookie tracking bugs for this issue: Affects: fedora-all [bug 1359819] nodejs-tough-cookie-2.3.1-1.fc24 has been pushed to the Fedora 24 stable repository. If problems still persist, please make note of it in this bug report. If tough-cookie module is used to parse Cookie header value, this flaw could cause it to use excessive amount of CPU time (cookie header takes long to parse). The actual impact depends on the maximum value length that can be received by the application. If node.js is deployed behind a web server such as Apache httpd or nginx, default header size limits of those servers (4-8K): http://stackoverflow.com/questions/686217/maximum-on-http-header-values#8623061 greatly mitigate impact of this issue. node.js directly expose to the internet can process larger headers, and hence possible impact is higher.
