✅ Remediation
For OpenShift Container Platform 4.6 see the following documentation, which will be updated shortly for this release, for important instructions on how to upgrade your cluster and fully apply this asynchronous errata update: https://docs.openshift.com/container-platform/4.6/release_notes/ocp-4-6-release-notes.html Details on how to access this content are available at https://docs.openshift.com/container-platform/4.6/updating/updating-cluster-cli.html Workaround: Jetty users should create temp folders outside the normal /tmp structure, and ensure that their permissions are set so as not to be accessible by an attacker.
