CVE-2023-0751: Freebsd

Medium severity, CVSS 6.5. EPSS: 0.6% chance of exploitation in the next 30 days.

When GELI reads a key file from standard input, it does not reuse the key file to initialize multiple providers at once resulting in the second and subsequent devices silently using a NULL key as the user key file. If a user only uses a key file without a user passphrase, the master key is encrypted with an empty key file allowing trivial recovery of the master key.

Affected products

• Freebsd Freebsd: version 12.3 only; version 12.4 only; version 13.1 only
