Milan Broz discovered that cryptsetup incorrectly handled LUKS2
reencryption recovery. An attacker with physical access to modify the
encrypted device header may trigger the device to be unencrypted the next
time it is mounted by the user.

On Ubuntu 20.04 LTS, this issue was fixed by disabling the online
reencryption feature.
