UNKNOWNCVE-2021-23386

Potential memory exposure in dns-packet

Platform

nodejs

Component

dns-packet

Fixed in

5.2.2

This affects the package dns-packet before versions 1.3.2 and 5.2.2. It creates buffers with allocUnsafe and does not always fill them before forming network packets. This can expose internal application memory over unencrypted network when querying crafted invalid domain names.

How to fix

Actualice el paquete dns-packet a la versión 5.2.2 o superior. Esto corrige la vulnerabilidad de exposición de memoria al asegurar que los buffers se llenen correctamente antes de formar paquetes de red. Ejecute `npm install dns-packet@latest` para actualizar.
