On June 17, 2019, Netflix researchers announced three vulnerabilities that have been discovered in the FreeBSD and Linux kernels. The vulnerabilities gives attackers the possibility to induce a denial-of-service by clogging network I/O on affected systems. This attack will result in a system crash of the server or instance.
Since the announcement, our engineers have been mapping out the impact of these vulnerabilities and have taken several measures to protect the Fuga Cloud services. Yesterday we have implemented a fix so that the systems of Fuga Cloud are no longer vulnerable for this attack.
Despite that the systems of Fuga Cloud are now well protected it is still possible that instance of customers can be affected by this vulnerability. For maximum security, we asked all our customers to make sure that the kernel of their instances are up-to-date. We have described here how you can upgrade the kernel of your instance to the latest version. In addition to this article on Fuga.cloud, we have also informed our customers by e-mail.
