Descriptions

The `'path'` module in the Node.js 4.x release line contains a potential regular expression denial of service (ReDoS) vector. The code in question was replaced in Node.js 6.x and later so this vulnerability only impacts all versions of Node.js 4.x. The regular expression, `splitPathRe`, used within the `'path'` module for the various path parsing functions, including `path.dirname()`, `path.extname()` and `path.parse()` was structured in such a way as to allow an attacker to craft a string, that when passed through one of these functions, could take a significant amount of time to evaluate, potentially leading to a full denial of service.

El módulo "path" en la línea de distribución 4.x de Node.js cointiene un vector potencial de denegación de servicio con expresiones regulares (ReDoS). El código en cuestión se reemplazó en Node.js 6.x y siguientes, por lo que esta vulnerabilidad solo impact a todas las versiones de Node.js 4.x. La expresión regular "splitPathRe", empleada en el módulo "path" para las diversas funciones de análisis de ruta, incluyendo "path.dirname()", "path.extname()" y "path.parse()" se estructuró de tal forma que permite que un atacante manipule una cadena que, al pasarse por una de estas funciones, podría gastar mucho tiempo para evaluar. Esto podría conducir a una denegación de servicio (DoS) completa.
