Security vulnerabilities (CVE 2017- 5715, CVE 2017- 5753, CVE 2017- 5754, SA-00088)
Malicious code utilizing a new method of side-channel analysis and running locally on a normally operating platform has the potential to allow the inference of data values from memory. This issue takes advantage of techniques commonly used in many modern processor architectures.
Elevation of Privilege / Information Disclosure
The exploits do not have the potential to corrupt, modify or delete data.
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.

List of affected systems
Fujitsu BS2000 Products
BS2000 Mainframes using /390 processors are not affected by this security issue.
Some of the BS2000 Mainframes use Intel processors. However, they are neither affected, as they run only system software provided by Fujitsu. The system software transforms user-created BS2000 applications into x86 programs. As a result, users cannot run their own x86 code to exploit the flaws. BS2000 systems are therefore safe and secure even without additional security patches.
For some optional BS2000 server components, such as Application Units, customers use other operating systems or hypervisors than BS2000 or VM2000. These customers should promptly deploy the patches provided by the respective manufacturer.
Fujitsu continues to monitor potential security issues for BS2000 products.
Fujitsu Storage Products
ETERNUS CS (CS200c, CS800, CS8000) appliances also use Intel processors. However, they are not affected by this security issue since they are self-contained data protection appliances. Only ETERNUS CS specific software is used; other software is not executed. The appliances’ safety settings ensure that only accesses required for operation are permitted. ETERNUS DX and AF series products are not affected by this vulnerability because no external program can be executed on them.
None of the ETERNUS LT (20, 40, 60, 260) libraries are affected by the Spectre & Meltdown processor bugs. Processors used in ETERNUS LT products are ARM Core based, but none are affected.
The processors used in Brocade SAN switch products are affected, however Brocade SAN products will only load and run officially signed Fabric OS firmware. Since only an officially signed and validated Fabric OS code image is allowed to run on a Brocade SAN hardware, the SAN switch products are not exploitable with respect to this specific set of vulnerabilities.
The ETERNUS CD10000 appliance also use Intel processors. However, they are not affected by this security issue since they are self-contained data protection appliances. Only ETERNUS CD10000 specific software is used; other software is not executed. The appliances’ safety settings ensure that only accesses required for operation are permitted.

Technical details of the exploits are documented online:
Referring to the recommendations made by third-party suppliers, Fujitsu strongly advises all customers to update affected products. Updates are provided through an updated version of the BIOS and the necessary patches for the dedicated operating system. Under some circumstances, enabling these updates may affect performance. The actual performance impact will depend on multiple factors, such as the specific CPU generation in your physical host and the system load (used application).
Fujitsu recommends that customers assess the performance impact for their system environment and make necessary adjustments.
The security of our products and our customers’ data is number one priority for Fujitsu. We are continuing to work with our partners in the industry to minimize any potential performance impact.
Fujitsu highly recommends customers to ensure that systems are physically secured where possible, and follow good security practices to ensure that only authorized personnel have access to devices.
