Descriptions

A Node.js application that allows an attacker to trigger a DNS request for a host of their choice could trigger a Denial of Service in versions < 15.2.1, < 14.15.1, and < 12.19.1 by getting the application to resolve a DNS record with a larger number of responses. This is fixed in 15.2.1, 14.15.1, and 12.19.1.

Una aplicación Node.js que permite a un atacante desencadenar una petición DNS para un host de su elección podría desencadenar una Denegación de servicio en las versiones anteriores a 15.2.1, versiones anteriores a 14.15.1 y versiones anteriores a 12.19.1 al conseguir que la aplicación resuelva un Registro DNS con un mayor número de respuestas. Esto es corregido en versiones 15.2.1, 14.15.1 y 12.19.1
