According to the information provided the potential impact of INTEL-SA-00322 is:

Denial of Service, Privilege Escalation

INTEL-SA-00320: 2020.1 IPU – Intel® Special Register Buffer Data Sampling (SRBDS) Advisory

A potential security vulnerability in some Intel® Processors may allow information disclosure. The detailed description of the vulnerabilities with at least a medium, high or critical CVSS base score is as follows:

CVE-2020-0543: Incomplete cleanup from specific special register read operations in some Intel® Processors may allow an authenticated user to potentially enable information disclosure via local access.

The audience may please refer to further publications by manufacturer Intel® on the 2020.1 IPU – Intel® Special Register Buffer Data Sampling (SRBDS) Advisory, such as the corresponding article Deep Dive: Special Register Buffa Data Sampling, for additional technical details about SRBDS.

Potential Impact:

According to the information provided the potential impact of INTEL-SA-00320 is:

Information Disclosure

2020.1 IPU – Intel® Processor Microcode (MCU) Updates

Additionally, multiple functional updates took place in Intel® Processor Microcode (MCU), affecting server EX/EP products (incl. D, W, X) and referring to:

CLX Patch Load Issue                         : CLX PRQ. Late patch load overrides perf. MSR (CLX)
MD_Clear Operations Errata for CLX : 2019.2 TAA fix allows some data leakage (CLX)
Temperature Based Voltage Compensation: Voltage guardband (CLX)
OC Mailbox preset                               : Removes requirement for BIOS loading of the 2019.2 OC Mailbox fix (SKX)
ADC/ADDDC                                         : Bug in ADC/ADDDC. M to M timing (SKX/CLX)
MCA Recovery                                     : Enable MCA recovery feature on std. RAS SKUs (SKX/CLX) (reboot required)

Higher rates of memory errors have been observed on Intel's Skylake (SKX SP) and Cascade Lake (CLX SP) based server platforms (code named Purley). Mitigations and workarounds are focused in the following area:
ECC Coverage: As a result of reallocating metadata bits to other features in SKX & CLX, Intel® modified the ECC algorithms to maximize full device coverage with available bits 

Rank Switching Speed Path: In 2017, Intel® provided a mitigation for a rank switching speed path marginality via a patch. Subsequent observations by Intel® suggested the patch did not fully address the issue. IPU 2020.1 BIOS option Receive Enable Average is turned off by default (recommended). 

RAS: Additionally, Intel has discovered three issues (Mesh 2 Mem Timeout, Incomplete Sparing (UEFI) and Rank Sparing Hang (UEFI)) in its Virtual Lockstep RAS (Reliability, Availability, Scalability) features used to enhance memory error correction (ADC & ADDDC). The RAS feature updates include: MCA Recovery, Advanced Memory

Test and Post Package Repair.

There were no additional CVEs assigned to these FUNCTIONAL updates.

INTEL-SA-00266: 2020.1 IPU – Intel® SSD Advisory

A potential security vulnerability in Intel® SSD (Solid State Drive) products may allow information disclosure. The detailed description of the vulnerabilities with at least a high or critical CVSS base score is as follows:

CVE-2020-0527: Insufficient control flow management in firmware in some Intel® Data Center SSDs may allow a privileged user to potentially enable information disclosure via local access.

Potential Impact:
According to the information provided the potential impact of INTEL-SA-00266 is:

Recommended Steps for Remediation

Remediation via BIOS Update

Step 1: Determine whether you have an affected system.

Refer to the https://www.fujitsu.com/hk/support/products/computing/pc/ap/ . 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 http://www.fujitsu-pc-asia.com/driversupport/selectioninterface/selection.html and follow these steps:

  • Select "Product Type t" (button)
  • Select "Series "
  • Select "Model  and OS "
  • Select " BIOS ".
  • Download and install the latest BIOS update package

 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 https://www.fujitsu.com/hk/support/products/computing/pc/ap/ . This list is updated regularly.

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

Step 2: Download and install the BIOS update package.

To download and install the BIOS update package, please go to the http://www.fujitsu-pc-asia.com/driversupport/selectioninterface/selection.html and follow these steps:

  • Select "Product Type t" (button)
  • Select "Series "
  • Select "Model  and OS "
  • Select " BIOS ".
  • Download and install the latest ME Firmware package

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 executing "drvload.exe \HECI.INF". The "HECI" driver can be extracted from the Intel® Active Management Technology (Intel® AMT) Driver Package for Windows.
