Description

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.

  • nodejs-minimist: Prototype pollution allows adding or modifying properties of Object.prototype using a constructor or __proto__ payload. (CVE-2020-7598)

  • kubernetes: Use of unbounded 'client' label in apiserver_request_total allows repeated, crafted HTTP requests to exhaust available memory and cause a crash. (CVE-2020-8552)

  • kubernetes: A flaw was found in Kubernetes that allows attackers on adjacent networks to reach services exposed on localhost ports and gain privileges or access confidential information for any services listening on localhost ports that are not protected by authentication. (CVE-2020-8558)

  • proglottis/gpgme: A use-after-free vulnerability was found in the Go GPGME wrapper library, github.com/proglottis/gpgme. (CVE-2020-8945)
