✅ Remediation

For OpenShift Container Platform 4.20 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.redhat.com/en/documentation/openshift_container_platform/4.20/html/release_notes/ Workaround: To mitigate this vulnerability, implement a timeout in your archive/zip processing logic to abort the operation if it exceeds a few seconds, preventing the application from consuming an excessive amount of resources.
