The rise of the Cloud Computing paradigm has led to security concerns, taking into account that resources are shared and mediated by a Hypervisor which may be targeted by rogue guest VMs and remote attackers. In order to better de ne the threats to which a cloud server's Hypervisor is exposed, the authors conducted a thorough analysis of the codebase of two popular open-source Hypervisors, Xen and KVM, followed by an extensive study of the vulnerability reports associated with them. Based on their findings, they propose a characterization of Hypervisor Vulnerabilities comprised of three dimensions: the trigger source, the attack vector, and the attack target.
