CRI-O: Arbitrary code execution in cri-o via abusing “kernel.core_pattern” kernel parameter

A flaw was found in CRI-O in the way it set kernel options for a pod. This issue allows anyone with rights to deploy a pod on a Kubernetes cluster that uses the CRI-O runtime to achieve a container escape and arbitrary code execution as root on the cluster node, where the malicious pod was deploy...

Why Security in Kubernetes Isn't the Same as in Linux: Part 2

Security for Kubernetes might not be quite the same as what you're used to. In our previous article, we covered why security is so important in both Linux on-premises servers and cloud Kubernetes clusters. We also talked about 3 major aspects of Linux server security — processes, network, and fil...
