Fujitsu Communication

Original release: May 15, 2019

Advisory Description

Intel® CSME, SPS, TXE and Intel® AMT 2019.1 QSR Advisory (INTEL-SA-00213)

Multiple potential security vulnerabilities in Intel® Converged Security and Management Engine (Intel® CSME), Server Platform Services (SPS), Trusted Execution Engine (TXE) and Intel® Active Management Technology (Intel® AMT) may allow users to potentially cause a denial of service, disclose information or an escalation of privilege. The detailed description of the vulnerabilities with high or critical CVSS base scores is as follows:

An insufficient access control vulnerability in Intel® Dynamic Application Loader software for Intel® CSME before versions 11.8.65, 11.11.65, 11.22.65, 12.0.35 and Intel® TXE 3.1.65, 4.0.15 may allow an unprivileged user to potentially enable an escalation of privilege via local access. (CVE-2019-0086)

An improper data sanitization vulnerability in subsystem in Intel® Server Platform Services before versions SPS_E5_04.00.04.381.0, SPS_E3_04.01.04.054.0, SPS_SoC-A_04.00.04.181.0, and SPS_SoC-X_04.00.04.086.0 may allow a privileged user to potentially enable an escalation of privilege via local access. (CVE-2019-0089)

An insufficient access control vulnerability in subsystem for Intel® CSME before version 12.0.35, Intel® Server Platform Services before version SPS_E3_05.00.04.027.0 may allow an unauthenticated user to potentially enable an escalation of privilege via physical access. (CVE-2019-0090)

A buffer overflow in subsystem in Intel® CSME before version 12.0.35 may allow an unauthenticated user to potentially enable an escalation of privilege via network access. (CVE-2019-0153)

A buffer overflow in subsystem in Intel® DAL (Dynamic Application Loader) before version 12.0.35 may allow a privileged user to potentially enable an escalation of privilege via local access. (CVE-2019-0170)

Potential Impact:

According to the information provided the potential impact of INTEL-SA-00213 is:

Denial of Service, Information Disclosure, Privilege Escalation

Intel® Processor Microcode (MCU) Updates (INTEL-SA-00233)

Multiple potential security vulnerabilities in Intel® processor microcode (MCU) may allow information disclosure. The detailed description of the vulnerabilities, known as Microarchitectural Data Sampling (MDS) or "ZombieLoad", with medium or high CVSS base scores is as follows:

  • Microarchitectural Store Buffer Data Sampling (MSBDS): Store buffers on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2018-12126)
  • Microarchitectural Load Port Data Sampling (MLPDS): Load ports on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2018-12127)
  • Microarchitectural Fill Buffer Data Sampling (MFBDS): Fill buffers on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2018-12130)

MCUs will work in conjunction with updates to Operating System (OS) and Virtual Machine Manage (VMM) software provided by others. Where utilized, Intel® SGX attestation services will report whether the MCU update is applied, beginning June 11, 2019.

Potential Impact:

According to the information provided the potential impact of INTEL-SA-00233 is:

Information Disclosure

Additionally, multiple potential functional issues in Intel® processor microcode (MCU) may cause unpredictable system behavior, platform stability problems or could result in a platform reset. The detailed description of the issues (no CVEs and no CVSS base scores – FUNCTIONAL issue) is as follows:

Amber Lake Y; Broadwell H,U,Y; Coffee Lake H,S,U; KabyLake G,H,S,U,X,Y,RU; Skylake H,S,U/Y,X; Whiskey Lake U

Under complex microarchitectural conditions, software using Intel® TSX (Transactional Synchronization Extensions) may result in unpredictable system behavior. Intel® has only seen this under synthetic testing conditions. Intel® is not aware of any commercially available software exhibiting this behavior.

Amber Lake Y; Broadwell H,U,Y; Coffee Lake H,S,U; Haswell H,U; KabyLake G,H,S,U,X,Y,RU; Skylake H,S,U/Y,X; Whiskey Lake U

"MCE" - Addresses potential platform stability issues which could result in platform reset and MCE (IA32_MCi_STATUS.MSCOD=00FH), (IA32_MCI_ STATUS. MCACOD=0150H).

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

Step 3: Use the Intel-SA-00185 Detection Tool to verify that the issue has been remediated.

Remediation via Management Engine (ME) 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 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 "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.
