Following this announcement we applied the necessary patches, thus reinforcing the existing security measures we had previously implemented. Over the past week, we have continued to study the vulnerability. As a preventative measure, we have decided that a reboot of KVM based VMs is required in order to ensure that all possible attack vectors have been mitigated.
We will contact affected customers directly via email to provide instructions on performing the reboot on their own. This preventive reboot will not affect customers we do not contact.
We will reboot the VMs of affected customers (who have not rebooted on their own) on November 19th. An outage of 30 minutes maximum is expected for each impacted VM.
If you have questions or encounter any problems regarding this issue, our support team is available to assist you.
