CVE-2023-5368: Freebsd

Medium severity, CVSS 6.5. EPSS: 0.7% chance of exploitation in the next 30 days.

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).

Affected products

• Freebsd Freebsd: before 12.4 (fixed in 12.4); from 13.0, before 13.2 (fixed in 13.2); version 12.4 only; version 13.2 only
