Linux vs. Zombieload

Linux vs. Zombieload (Malware and Vulnerabilities)

Red Hat noted all its Linux distributions from Red Hat Enterprise Linux (RHEL) 5 on up to the new RHEL 8 are affected. Platforms based on these Linux distros, such as Red Hat Virtualization and Red Hat OpenStack, are also vulnerable. To protect yourself, you'll need to patch the following Linux files: Kernel, kernel-rt, libvirt, qemu-kvm, qemu-kvm-rhev, and microcode_clt on all your systems. That said, because of the threat posed by vulnerability chaining (the ability to exploit one vulnerability by exploiting another one first), Red Hat strongly suggested that users update all systems even if they do not believe their configuration poses a direct threat. Red Hat's VP of operating system platforms, Denise Dumas, said: "Because these security updates may affect system performance, Red Hat has included the ability to enable these fixes selectively in order to better manage the impact on performance-sensitive workloads." The only real long-term fix -- for Linux and all other operating systems -- is when Intel introduces a new generation of processors.
