Overview

node is a JavaScript runtime built on Chrome's V8 JavaScript engine.

Affected versions of this package are vulnerable to DNS Rebinding. A Denial of Service can occur when the whitelist in /etc/hosts includes localhost6. If an attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the localhost6 domain.
