Fujitsu Communication | ||||||||||||||||||||||||||
| ||||||||||||||||||||||||||
Advisory Description | ||||||||||||||||||||||||||
Intel® CSME, SPS, TXE and Intel® AMT 2018.4 QSR Advisory (INTEL-SA-00185) | ||||||||||||||||||||||||||
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 escalate privileges, disclose information or cause a denial of service. The detailed description of the vulnerabilities with high CVSS base scores is as follows:
| ||||||||||||||||||||||||||
Potential Impact: | ||||||||||||||||||||||||||
According to the information provided the potential impact of INTEL-SA-00185 is: Denial of Service, Information Disclosure, Privilege Escalation | ||||||||||||||||||||||||||
Intel® Firmware (UEFI) 2018.4 QSR Advisory (INTEL-SA-00191) | ||||||||||||||||||||||||||
Multiple potential security vulnerabilities in Intel® firmware (UEFI) may allow for escalation of privilege, information disclosure or denial of service. The detailed description of the vulnerabilities with high CVSS base scores is as follows:
| ||||||||||||||||||||||||||
Potential Impact: | ||||||||||||||||||||||||||
According to the information provided the potential impact of INTEL-SA-00191 is: Denial of Service, Information Disclosure, Privilege Escalation | ||||||||||||||||||||||||||
Intel® Processor Microcode (MCU) Updates | ||||||||||||||||||||||||||
Multiple potential functional issues in Intel® processor microcode (MCU) may cause unpredictable system behavior, lead to a system hang 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: Broadwell E, EP, EP4S, EX; Skylake Server SP (H0, M0, U0); Skylake X, D, W; Haswell EX; Broadwell DE (A1, V1-3, Y0) "TSX" - In a synthetic software environment, certain Intel Transactional Synchronization Extensions (TSX) functions may interact in ways that could result in unpredictable system behavior. This would only occur in extremely rare circumstances. Intel is not aware of any commercially available software exhibiting this behavior, and this is issue is not security-related. Intel is releasing a microcode(MCU) based workaround to prevent such hypothetical behavior. Broadwell EP, EP4S, DE (V1-3, Y0); Haswell EX "RCOMP" - An RCOMP and package C6 exit can lead to a system hang that results in machine check bank 4 status register bits 31:24 with a value of 0x09, 0x71, or 0x73. It is possible for BIOS to contain a workaround for this erratum. Broadwell E, EP, EP4S, EX; Skylake Server SP (H0, M0, U0); Skylake X, D, W; Haswell EX, E/EP; Broadwell DE (A1, V1-3, Y0) "MCE" - Addresses potential platform stability issues which could result in platform reset and MCE(IA32_MCi_STATUS.MSCOD=00FH), (IA32_MCI_ STATUS. MCACOD=0150H). | ||||||||||||||||||||||||||

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. | ||||||||||||||||||||||||||
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:
| ||||||||||||||||||||||||||
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 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:
| ||||||||||||||||||||||||||
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. | ||||||||||||||||||||||||||
