FKIE_CVE-2023-5368
Vulnerability from fkie_nvd - Published: 2023-10-04 04:15 - Updated: 2024-11-21 08:41
Severity
Summary
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).
