Red Hat OpenShift Container Platform 3.9

source-to-image component of Openshift Container Platform before versions atomic-openshift 3.7.53, atomic-openshift 3.9.31 is vulnerable to a privilege escalation which allows the assemble script to run as the root user in a non-privileged container. An attacker can use this flaw to open network connections, and possibly other actions, on the host which are normally only available to a root user.

Kubernetes kube-apiserver allows access to custom resources via wrong scope

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service

An out of bound write can occur when patching an Openshift object using the 'oc patch' functionality in OpenShift Container Platform before 3.7. An attacker can use this flaw to cause a denial of service attack on the Openshift master api service which provides cluster management.

Kubernetes API Server JSON/YAML parsing vulnerable to resource exhaustion attack

A flaw was discovered in the HPACK decoder of HAProxy, before 1.8.14, that is used for HTTP/2. An out-of-bounds read access in hpack_valid_idx() resulted in a remote crash and denial of service.

kubectl cp allows symlink directory traversal

kubectl cp path traversal

The OpenShift image import whitelist failed to enforce restrictions correctly when running commands such as "oc tag", for example. This could allow a user with access to OpenShift to run images from registries that should not be allowed.

The OpenShift Enterprise cluster-read can access webhook tokens which would allow an attacker with sufficient privileges to view confidential webhook tokens.
