In 2.16 and earlier, there is an integer overflow in media stream buffer size calculation when processing SDP with asymmetric ptime configuration. The overflow may result in an undersized buffer allocation, which can lead to unexpected application termination or memory corruption This vulnerability is fixed in 2.17."

En 2.16 y versiones anteriores, existe un desbordamiento de entero en el cálculo del tamaño del búfer de flujo de medios al procesar SDP con configuración ptime asimétrica. El desbordamiento puede resultar en una asignación de búfer de tamaño insuficiente, lo que puede llevar a la terminación inesperada de la aplicación o a corrupción de memoria. Esta vulnerabilidad está corregida en 2.17."
