Zero-Day Vulnerability: Venom

VENOM Zero-Day May Affect Thousands of Cloud, Virtualization Products
Bigger than Heartbleed, ‘Venom’ security vulnerability threatens most datacenters

New zero-day vulnerability has been identified today.  Attackers can exploit the vulnerability that exists in the open-source QEMU hypervisor. By doing so they can break out of the affected virtual machine and have access to the physical server and the other virtual machines.  QEMU is utilized in some capacity in other more widely used virtualization products such as Xen, KVM (kernel-based virtual machine) and Oracle VM VirtualBox.  Venom will be extremely detrimental for data centers.
Not affected: VMware, Microsoft Hyper-V, and Bochs hypervisors.
