Bug Description

Intel has released a new microcode version which includes updates for
further CPU models providing the necessary code for SSBD as well as the
recently disclosed L1TF vulnerability

https://downloadcenter.intel.com/download/28039/Linux-Processor-Microcode-Data-File

Debian should release an update shortly.

Please consider packaging this version to enable mitigations.

20180807 has license problems, and cannot be distributed at the moment.

Debian is waiting for Intel to address the matter. I assume Canonical will do the same.
