Description

On an msdosfs filesystem, the &amp;#39;truncate&amp;#39; or &amp;#39;ftruncate&amp;#39; system calls under certain circumstances populate the additional space in the file with unallocated data from the underlying disk device, rather than zero bytes.<br /> <br /> 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).<br /> <br />
