Remote DoS Vulnerability in Node.js by Node.js Foundation

CVE-2017-11499

What is CVE-2017-11499?

Node.js versions ranging from v4.0 to v4.8.3 and all versions of v5.x, v6.x, v7.x, and v8.x prior to v8.1.3 are vulnerable to hash flooding remote Denial of Service (DoS) attacks. This issue arises from the use of a constant HashTable seed across the same release version, effectively preventing the diffusion of hash values. The problem was exacerbated by the default configuration that enabled V8 snapshots, leading to predictable behavior on application startup. Attackers could exploit this weakness to overload the application, resulting in service disruption.
