      "value": "Socket.IO enables bidirectional and low-latency communication for every platform. Prior to 4.2.7, 3.4.5, and 3.3.6, a specially crafted Socket.IO packet can make the server wait for a large number of binary attachments and buffer them, which can be exploited to make the server run out of memory. This vulnerability is fixed in 4.2.7, 3.4.5, and 3.3.6."

      "value": "Socket.IO permite comunicación bidireccional y de baja latencia para cada plataforma. Antes de 4.2.7, 3.4.5, y 3.3.6, un paquete de Socket.IO manipulado específicamente puede hacer que el servidor espere un gran número de adjuntos binarios y los almacene en búfer, lo cual puede ser explotado para agotar la memoria del servidor. Esta vulnerabilidad está corregida en 4.2.7, 3.4.5, y 3.3.6."
