Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

Node.js 0.12.x before 0.12.9, 4.x before 4.2.3, and 5.x before 5.1.1 does not ensure the availability of a parser for each HTTP socket, which allows remote attackers to cause a denial of service (uncaughtException and service outage) via a pipelined HTTP request.

Mitigation

Install update from vendor's website.
