CVE-2022-3341

Estado: AnalizadaMedia (5.3)—

Se descubrió un problema de desreferencia a puntero nulo en 'FFmpeg' en la función decode_main_header() del archivo libavformat/nutdec.c. La falla ocurre porque la función no verifica el valor de retorno de avformat_new_stream() y desencadena el error de desreferencia del puntero nulo, lo que provoca que la aplicación falle.
