Validation Bypass

github.com/cri-o/cri-o is vulnerable to Validation Bypass. When an attacker creates a pod with a hostIPC and hostNetwork kernel namespace, the attacker is able to apply sysctls from the list of safe sysctls specified for the cluster resulting in unauthorized access due to insufficient validations...

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...

Unprivileged pod using `hostPath` can side-step active LSM when it is SELinux

Impact Containers launched through containerd’s CRI implementation on Linux systems which use the SELinux security module and containerd versions since v1.5.0 can cause arbitrary files and directories on the host to be relabeled to match the container process label through the use of...

CVE-2021-43816

containerd is an open source container runtime. On installations using SELinux, such as EL8 CentOS, RHEL, Fedora, or SUSE MicroOS, with containerd since v1.5.0-beta.0 as the backing container runtime interface CRI, an unprivileged pod scheduled to the node may bind mount, via hostPath volume, any...
