Side-Channel Analysis Method (Spectre & Meltdown) Security Review

Side-Channel Analysis Method

(Spectre & Meltdown) Security Review

Fujitsu Communication

Latest Update: 25.06.2018

Reference: Intel 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.

Impact:

Elevation of Privilege / Information Disclosure

The exploits do not have the potential to corrupt, modify or delete data.

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 can be found here:

Intel has notified that the microcode updates they have provided with OEMs have a problem which might cause reboot issues and unpredictable system behaviour.

https://security-center.intel.com/advisory.aspx?intelid=INTEL-SA-00088&languageid=en-fr

Fujitsu is working with Intel on new BIOS. We will issue the updated BIOS as soon as possible once Intel reissues microcode updates.
