CVE-2022-1708 – cri-o: memory exhaustion on the node when access to the kube api
https://notcve.org/view.php?id=CVE-2022-1708
A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with access to the Kube API. The ExecSync request runs commands in a container and logs the output of the command. This output is then read by CRI-O after command execution, and it is read in a manner where the entire file corresponding to the output of the command is read in. Thus, if the output of the command is large it is possible to exhaust the memory or the disk space of the node when CRI-O reads the output of the command. The highest threat from this vulnerability is system availability. • https://bugzilla.redhat.com/show_bug.cgi?id=2085361 https://github.com/cri-o/cri-o/commit/f032cf649ecc7e0c46718bd9e7814bfb317cb544 https://github.com/cri-o/cri-o/security/advisories/GHSA-fcm2-6c3h-pg6j https://access.redhat.com/security/cve/CVE-2022-1708 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2022-0811 – CRI-O: Arbitrary code execution in cri-o via abusing “kernel.core_pattern” kernel parameter
https://notcve.org/view.php?id=CVE-2022-0811
A flaw was found in CRI-O in the way it set kernel options for a pod. This issue allows anyone with rights to deploy a pod on a Kubernetes cluster that uses the CRI-O runtime to achieve a container escape and arbitrary code execution as root on the cluster node, where the malicious pod was deployed. Se ha encontrado un fallo en CRI-O en la forma de establecer las opciones del kernel para un pod. Este problema permite a cualquier persona con derechos desplegar un pod en un clúster Kubernetes que usa el tiempo de ejecución de CRI-O para lograr un escape del contenedor y la ejecución de código arbitrario como root en el nodo del clúster, donde fue desplegado el pod malicioso • https://bugzilla.redhat.com/show_bug.cgi?id=2059475 https://github.com/cri-o/cri-o/security/advisories/GHSA-6x2m-w449-qwx7 https://access.redhat.com/security/cve/CVE-2022-0811 • CWE-94: Improper Control of Generation of Code ('Code Injection') •
