Improper Check or Handling of Exceptional Conditions

Summary

KubeVirt is a virtual machine management add-on for Kubernetes. Prior to version 1.7.0-beta.0, a logic flaw in the virt-controller allows an attacker to disrupt the control over a running VMI by creating a pod with the same labels as the legitimate virt-launcher pod associated with the VMI. This can mislead the virt-controller into associating the fake pod with the VMI, resulting in incorrect status updates and potentially causing a Denial-of-Service (DoS).
