Security researchers identified speculative execution side-channel
methods which have the potential to improperly gather sensitive data
from multiple types of computing devices with different vendors
processors and operating systems.

This update requires an update to the intel-microcode package, which is
non-free. It is related to DLA-1446-1 and adds more mitigations for
additional types of Intel processors.
