  This microcode update provides the Intel 20180807 microcode release
  that adds the processor microcode side of fixes and mitigations for
  the now publically known security issue affected Intel processors
  called L1 Terminal Fault (L1TF) for most Intel processors since
  Intel Core gen2:

  Systems with microprocessors utilizing speculative execution and Intel
  Software Guard Extensions (Intel SGX) may allow unauthorized disclosure
  of information residing in the L1 data cache from an enclave to an
  attacker with local user access via side-channel analysis (CVE-2018-3615).

  Systems with microprocessors utilizing speculative execution and address
  translations may allow unauthorized disclosure of information residing in
  the L1 data cache to an attacker with local user access via a terminal
  page fault and side-channel analysis (CVE-2018-3620).

  Systems with microprocessors utilizing speculative execution and address
  translations may allow unauthorized disclosure of information residing in
  the L1 data cache to an attacker with local user access with guest OS
  privilege via a terminal page fault and side-channel analysis
  (CVE-2018-3646).

  The impact of the L1TF security issues:
  * Malicious applications may be able to infer the values of data in the
    operating system memory, or data from other applications.
  * A malicious guest virtual machine (VM) may be able to infer the values
    of data in the VMM’s memory, or values of data in the memory of other
    guest VMs.
  * Malicious software running outside of SMM may be able to infer values
    of data in SMM memory.
  * Malicious software running outside of an Intel® SGX enclave or within an
    enclave may be able to infer data from within another Intel SGX enclave.

  NOTE! You also need to install one of the 4.14.64 based kernel updates
  to get the current operating system side set of fixes and mitigations
  for L1TF. That means either kernel (mga#23458), kernel-tmb (mga#23459)
  or kernel-linus (mga#23460).
