CVE-2023-5368 Information

Description

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).
