intel-microcode: update to 20180703 drop

[Steve Beattie]

Intel has released a new version of their microcode, that starts to address Rogue System Register Read (RSRE, aka Spectre Variant 3a, CVE-2018-3640) and Speculative Store Bypass (SSB, aka Spectre Variant 4, CVE-2018-3639).

Reference: https://downloadcenter.intel.com/download/27945/Linux-Processor-Microcode-Data-File

[Steve Beattie (sbeattie)]

This was fixed in cosmic in https://launchpad.net/ubuntu/+source/intel-microcode/3.20180703.2ubuntu1 ; pacakge for trusty, xenial, and bionic are available for testing in the ubuntu-security-proposed ppa: https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/ . Please note that packages in this ppa are for testing only and have not been widely tested, and thus should not be used in production.

Thanks.

[Danny Gershman (radius314)]

Any update on the testing effort? The timeline on a release?

[Markus Schade (lp-markusschade)]

We have been running this microcode on Xenial in production for the last month on a few hundred SNB, IVB, HSW, BDW and SKL systems without seeing any regression.

Seems like Intel has gotten it right this time on the first try.

[Markus Schade (lp-markusschade)]

Since the L1TF has been disclosed yesterday, the update has become even more urgent. The MCU also contains the necessary mitigations for SGX as well.

[Markus Schade (lp-markusschade)]

As the 20180807 MCU can currently not be distributed due to licensing issues, this update is even more important as it at least provides the SSBD and L1TF fixes for server CPUs.
