These vulnerabilities are due to incorrect processing of certain LLDP packets at ingress time. An attacker could exploit these vulnerabilities by sending crafted LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, which could cause the device to crash and 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)."}, {"lang": "es", "value": "M\u00faltiples vulnerabilidades en la implementaci\u00f3n del Link Layer Discovery Protocol (LLDP) para Cisco Video Surveillance 7000 Series IP Cameras, podr\u00edan permitir a un atacante adyacente no autenticado causar una p\u00e9rdida de memoria, lo que podr\u00eda conllevar a una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado.
