Descriptions
On an msdosfs filesystem, the 'truncate' or 'ftruncate' system calls under certain circumstances populate the additional space in the file with unallocated data from the underlying disk device, rather than zero bytes.
This may permit a user with write access to files on a msdosfs filesystem to read unintended data (e.g. from a previously deleted file).
En un sistema de archivos msdosfs, las llamadas al sistema 'truncate' o 'ftruncate' bajo ciertas circunstancias llenan el espacio adicional en el archivo con datos no asignados del dispositivo de disco subyacente, en lugar de cero bytes. Esto puede permitir que un usuario con acceso de escritura a archivos en un sistema de archivos msdosfs lea datos no deseados (por ejemplo, de un archivo previamente eliminado).
