      "value": "Before correction, the\u00a0copy_file_range\u00a0system call checked only for the CAP_READ and CAP_WRITE capabilities on the input and output file descriptors, respectively.  Using an offset is logically equivalent to seeking, and the system call must additionally require the CAP_SEEK capability.\n\nThis incorrect privilege check enabled sandboxed processes with only read or write but no seek capability on a file descriptor to read data from or write data to an arbitrary location within the file corresponding to that file descriptor."

      "value": "Antes de la correcci\u00f3n, la llamada al sistema copy_file_range verific\u00f3 solo las capabilities CAP_READ y CAP_WRITE en los descriptores de archivos de entrada y salida, respectivamente. Usar un desplazamiento es l\u00f3gicamente equivalente a buscar, y la llamada al sistema debe requerir adicionalmente la capability CAP_SEEK. Esta verificaci\u00f3n de privilegios incorrecta permiti\u00f3 que los procesos aislados con solo lectura o escritura pero sin capacidad de b\u00fasqueda en un descriptor de archivo leyeran o escribieran datos en una ubicaci\u00f3n arbitraria dentro del archivo correspondiente a ese descriptor de archivo."
