      "value": "A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for the Cisco Video Surveillance 7000 Series IP Cameras firmware could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper management of memory resources, referred to as a double free. An attacker could exploit this vulnerability by sending crafted LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Note: LLDP is a Layer 2 protocol. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent)."

      "value": "Una vulnerabilidad en la Implementaci\u00f3n del Protocolo de Detecci\u00f3n de la Capa de Enlace (LLDP) para el firmware de las c\u00e1maras IP de la serie 7000 de Cisco Video Surveillance podr\u00eda permitir a un atacante adyacente no autenticado causar una condici\u00f3n de denegaci\u00f3n de servicio (DoS). Esta vulnerabilidad es debido a una administraci\u00f3n inapropiada de los recursos de memoria, denominada doble liberaci\u00f3n. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de paquetes LLDP dise\u00f1ados a un dispositivo afectado. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir al atacante hacer que el dispositivo afectado se recargue, resultando en una condici\u00f3n de DoS. Nota: LLDP es un protocolo de capa 2. Para explotar estas vulnerabilidades, un atacante debe estar en el mismo dominio de difusi\u00f3n que el dispositivo afectado (Capa 2 adyacente)."
