Side Channel Vulnerability(Also known as Spectre and Meltdown)
'Meltdown' and 'Spectre' Information
There are indications that the Meltdown vulnerability is exclusive to Intel processors, while the Spectre vulnerability can possibly affect some Intel, AMD, and ARM processors. Procedures are available to help protect devices from the Meltdown and Spectre security vulnerabilities.
Intel released a noteworthy article on January 22, 2018: Root Cause of Reboot Issue Identified; Updated Guidance for Customer and Partners
It is strongly recommended that baseline performance testing is conducted prior to applying patches to production as performance may be impacted.
Vendors and manufacturers have provided the below information and/or mitigation solutions to address vulnerabilities.
Updates have been released for Apple iOS High Sierra, and Safari on Sierra and El Capitan to help defend against Spectre. Further information is available at: https://support.apple.com/en-us/HT208394
Amazon Web Services (AWS) is aware of the issue described in CVE-2017-5715, CVE-2017-5753, and CVE-2017-5754. This is a vulnerability that has existed for more than 20 years in modern processor architectures like Intel, AMD, and ARM across servers, desktops, and mobile devices. All instances across the Amazon EC2 fleet are protected from all known threat vectors from the CVEs previously listed. Customers’ instances are protected against these threats from other instances. We have not observed meaningful performance impact for the overwhelming majority of EC2 workloads. We will keep customers apprised of additional information with updates to our security bulletin, which can be found here.
More information on these bulletins are available at the Amazon Linux AMI Security Center.

F5 – K91229003: Side-channel processor vulnerabilities CVE-2017-5715, CVE-2017-5753, and CVE-2017-5754
First and foremost, there is no exposure on BIG-IP products by way of the data plane. All exposure is limited to the control plane (also known as the management plane).
Furthermore, on the control plane, the vulnerabilities are exploitable only by four authorized, authenticated account roles: Administrator, Resource Administrator, Manager, and iRules Manager. You must be authorized to access the system in one of these roles to even attempt to exploit the vulnerabilities.
All three vulnerabilities require an attacker who can provide and run binary code of their choosing on the BIG-IP platform.
These conditions severely restrict the exposure risk of BIG-IP products.
F5 continues to investigate the impact of the Spectre and Meltdown vulnerabilities on their products. F5 is focused on providing patched releases as soon as they have fully tested and verified fixes. F5 will update this article with the most current information as soon as it is confirmed.
