SUSE CVE-2022-0532

An incorrect sysctls validation vulnerability was found in CRI-O 1.18 and earlier. The sysctls from the list of "safe" sysctls specified for the cluster will be applied to the host if an attacker is able to create a pod with a hostIPC and hostNetwork kernel namespace...

podman: podman machine spawns gvproxy with port bound to all IPs

A flaw was found in podman. The podman machine function used to create and manage Podman virtual machine containing a Podman process spawns a gvproxy process on the host system. The gvproxy API is accessible on port 7777 on all IP addresses on the host. If that port is open on the host's firewall...

CVE-2022-31076 Malicious Message can crash CloudCore in KubeEdge

KubeEdge is built upon Kubernetes and extends native containerized application orchestration and device management to hosts at the Edge. In affected versions a malicious message can crash CloudCore by triggering a nil-pointer dereference in the UDS Server. Since the UDS Server only communicates...

CloudCore UDS Server: Malicious Message can crash CloudCore

Impact A malicious message can crash CloudCore by triggering a null-pointer dereference in the UDS Server. Since the UDS Server only communicates with the CSI Driver on the cloud side, the attack is limited to the local host network. As such, an attacker would already need to be an authenticated...

GHSA-W2J5-3RCX-VX7X Sysctls applied to containers with host IPC or host network namespaces can affect the host

Impact Before setting the sysctls for a pod, the pods namespaces must be unshared created. However, in cases where the pod is using a host network or IPC namespace, a bug in CRI-O caused the namespace creating tool pinns to configure the sysctls of the host. This allows a malicious user to set...

Server Side Request Forgery (SSRF) in Kubernetes

The Kubernetes kube-controller-manager in versions v1.0-1.14, versions prior to v1.15.12, v1.16.9, v1.17.5, and version v1.18.0 are vulnerable to a Server Side Request Forgery SSRF that allows certain authorized users to leak up to 500 bytes of arbitrary information from unprotected endpoints...

CVE-2021-25737 Holes in EndpointSlice Validation Enable Host Network Hijack

A security issue was discovered in Kubernetes where a user may be able to redirect pod traffic to private networks on a Node. Kubernetes already prevents creation of Endpoint IPs in the localhost or link-local range, but the same validation was not performed on EndpointSlice IPs...

kubernetes: Holes in EndpointSlice Validation Enable Host Network Hijack

A security issue was discovered in Kubernetes where an authorized user may be able to redirect traffic to private networks on a Node. An untrusted user could exploit this by creating or modifying EndpointSlices to point to localhost or link-local addresses...

GHSA-36XW-FX78-C5R4 containerd-shim API Exposed to Host Network Containers

Impact Access controls for the shim’s API socket verified that the connecting process had an effective UID of 0, but did not otherwise restrict access to the abstract Unix domain socket. This would allow malicious containers running in the same network namespace as the shim, with an effective UID...
