Rackspace Response to Meltdown and Spectre

On January 3, 2018, Rackspace was made aware of CPU architecture vulnerabilities associated with Intel, AMD, ARM and other providers. Information about this vulnerability has been provided by Google and is available within the following Google posts:

These issues were originally uncovered by Google’s Project Zero. Their research findings show that an unauthorized party may read sensitive information in the system’s memory such as passwords, encryption keys, or sensitive information open in applications.

The remainder of this update is addressed to our Fanatical Support for GCP customers specifically. For updates about our other Rackspace supported hosting environments, please refer to the Rackspace blog.


Details about the security vulnerabilities can be found in CVE-2017-5753, CVE-2017-5715, and CVE-2017-5754. Google’s security bulletin regarding these vulnerabilities can be found here.

There is not a single fix

There is no single fix for all three security vulnerabilities. Many vendors have patches available for one or more of these attacks.

Google Cloud Platform (GCP) Response

Within Google Cloud Platform, the vulnerability affects two components: the underlying GCP resources and the Google Cloud Services (GCE, GKE, Dataproc, etc.) that run on those resources. Google has confirmed that they have mitigated underlying GCP resources impacted by the vulnerability. For the remaining Google Cloud Services impacted by this vulnerability, Google has recommended that customers take further action.

Next Steps

For Aviator supported projects, your Rackspace Cloud Engineering team will coordinate with you to define the next steps needed to mitigate this vulnerability. We are analyzing your current project(s) to understand the scope of work required and will contact you within the next 24 hours.

For projects that are not supported by Rackspace Managed Services (i.e., Runway projects), we recommend that customers undertake mitigation steps per the documentation provided by Google in the security links provided above.
