The vulnerability is caused by\ninsufficient bounds checking when processing RTSP custom authentication data. A\nremote attacker may exploit this vulnerability by sending a crafted RTSP\nrequest, resulting in memory corruption, denial of service, or potentially\narbitrary code execution."

      "value": "Una vulnerabilidad de desbordamiento de búfer basado en pila no autenticada existe en ssvr en GeoVision GV-LPC2011 y GV-LPC2211 V1.12 y anteriores. La vulnerabilidad es causada por una comprobación de límites insuficiente al procesar datos de autenticación personalizados de RTSP. Un atacante remoto puede explotar esta vulnerabilidad enviando una solicitud RTSP manipulada, lo que resulta en corrupción de memoria, denegación de servicio, o potencialmente ejecución de código arbitrario."
