Intel® Processor Microcode (MCU) Updates 2019.2 IPU Advisory
Additionally, multiple potential functional issues (or erratum) in Intel® processor microcode (MCU) may lead to a) an incorrect overwrite of fill buffers affected by MDS (Microarchitectural Data Sampling), b) Spectre variant 2 (BTI) mitigations not being fully effective, c) systems exhibiting unpredictable system behavior executing instructions and d) allowing an attacker to access confidential SGX enclave data using side-channel methods.

The detailed description of the issues (no newly assigned CVEs; some FUNCTIONAL issue only) is as follows:

MD_CLEAR OPERATIONS: May Overwrite Fill Buffers With Data That is Not Constant

On processors that enumerate the MD_CLEAR CPUID bit, the VERW mem instruction will overwrite buffers affected by MDS (Microarchitectural Data Sampling). On processors also affected by this erratum, VERW may overwrite portions of the fill buffers with recently stored data rather than uniformly constant data.

Software using VERW to prevent MDS side channel methods from revealing previous accessed data may not prevent those side-channel methods from inferring the value stored by the most recent preceding stores to certain address offsets.

TA INDIRECT SHARING: STIBP, IBRS and IBPB May Not Function as Intended

Spectre variant 2 (Branch Target Injection) mitigations may not be fully effective in certain corner cases. This affects one or more of STIBP, IBRS and IBPB MSR bits. The "retpoline" mitigation technique is not affected. This also does not affect parts that are run with Hyper-Threading (HT) disabled.

SHUF: Unpredictable Behavior When Executing X87, AVX or Integer Divide Instructions

Under complex micro-architectural conditions, executing an X87 or AVX or integer divide instruction may result in unpredictable system behavior.

When this erratum occurs, the system may exhibit unpredictable system behavior. Intel has not observed this erratum with any commercially available software.

EGETKEY: SGX Key Confidentiality May be Compromised

Under complex micro-architectural conditions, it may be possible for the value of SGX keys to be inferred using side-channel methods.

If exposed, such keys could allow an attacker to access confidential SGX enclave data. Processors that do not support Hyper-Threading (HT) are not affected by this issue.

Affection and Remediation

Affected Fujitsu Products
A number of Fujitsu products are affected by these vulnerabilities. Fujitsu is working to distribute patches for all affected products that are currently supported. Older systems that are no longer supported will not be patched.

An overview of the affected Client Computing Devices (e.g. CELSIUS, ESPRIMO, FUTRO, LIFEBOOK, STYLISTIC) and Server products (PRIMERGY and PRIMEQUEST) can be found here:

List of affected Fujitsu products (APL)

This page will be updated regularly as soon as new information is available. Besides a list of affected systems, also more detailed advice will follow.

NOTE: The above list of affected Fujitsu products (APL) was already released, as part of the Fujitsu PSIRT's 2019.2 INTEL PLATFORM UPDATE (IPU) Security Advisory, in November 2019.

The 2019.2 INTEL PLATFORM UPDATE (IPU) INTEL-SA-00307 Security Advisory is already covered, by the above list of affected Fujitsu products (APL).

Recommended Steps for Remediation
Remediation via BIOS Update
Step 1: Determine whether you have an affected system.
Refer to the list of affected Fujitsu products (APL). This list is updated regularly.

Before proceeding, please check the expected availability of the relevant BIOS update package.

Step 2: Download and install the BIOS update package.
To download and install the BIOS update package, please go to the Fujitsu Technical Support page and follow these steps:
  • Select "Select a new Product" (button)
  • Select "Browse for Product"
  • Select "product line"
  • Select "product group" and "product family".
  • Download and install the latest BIOS update package
Step 3: Use the Intel-SA-00185 Detection Tool to verify that the issue has been remediated.

Remediation via Management Engine (ME) Update
Updating the ME firmware is an alternative to updating the BIOS and used when a BIOS update is not planned. However, it may only be available for some specific Client Computing Devices.

Step 1: Determine whether you have an affected system.
Refer to the list of affected Fujitsu products (APL). This list is updated regularly.

Before proceeding, please check the expected availability of the relevant ME update package.

Step 2: Download the ME update package.
To download the ME update package, please go to the Fujitsu Technical Support page and follow these steps:
  • Select "Select a new Product" (button)
  • Select "Browse for Product"
  • Select "product line"
  • Select "product group" and "product family".

Step 3: Preparation.
After downloading the .zip file, containing the ME Firmware Update Pack, extract all files/directories/subdirectories in the Firmware.ME directory (\Firmware.ME) of the .zip file to the desired directory on the hard drive.

Step 4: ME Update Procedure.
The "Firmware.ME" directory contains the ME update files which can be used in Windows environment. Run "update.bat" in Windows cmd environment with administrative privileges to start the ME flash procedure. Please choose 32-bit or 64-bit directory if using a Windows 32-bit or a Windows 64-bit installation.

Hints:
  • To run the ME Update procedure using a Windows installation, it is necessary to have the Windows "HECI" driver installed. Please use the Intel(R) Active Management Technology Driver package for Windows.
  • To run the ME Update procedure using a Windows PE installation, it is necessary to have the Windows "HECI" driver installed. This can be done at runtime by "drvload.exe< Path to HECI.INF>\HECI.INF". The "HECI" driver can be extracted from the Intel(R) Active Management Technology Driver package for Windows.
