A flaw was found in cri-o, as a result of all pod-related processes being placed in the same memory cgroup. This can result in container management (conmon) processes being killed if a workload process triggers an out-of-memory (OOM) condition for the cgroup. An attacker could abuse this flaw to get host network access on an cri-o host.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2992 advisory.

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

    Security Fix(es):

    * cri-o: A flaw was found in cri-o that can result in container management (conmon) processes being killed     if a workload process triggers an out-of-memory (OOM) condition for the cgroup. (CVE-2019-14891)

    * 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)

    * openshift/console: A flaw allowed text injection on error pages with a crafted URL. (CVE-2020-10715)
