Description

All versions of Node.js 9.x and 10.x are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node process which provides an http server supporting TLS server to crash. This can be accomplished by sending duplicate/unexpected messages during the handshake. This vulnerability has been addressed by updating the TLS implementation.

How to fix

Upgrade to a fixed version: Node.js 10.4.1, 9.11.2. Check the vendor advisory for mitigations.
