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-2021-25746 – Ingress-nginx directive injection via annotations
https://notcve.org/view.php?id=CVE-2021-25746
A security issue was discovered in ingress-nginx where a user that can create or update ingress objects can use .metadata.annotations in an Ingress object (in the networking.k8s.io or extensions API group) to obtain the credentials of the ingress-nginx controller. In the default configuration, that credential has access to all secrets in the cluster. Se ha detectado un problema de seguridad en ingress-nginx en el que un usuario que puede crear o actualizar objetos ingress puede usar .metadata.annotations en un objeto Ingress (en el grupo networking.k8s.io o extensions API) para obtener las credenciales del controlador ingress-nginx.

CVE-2022-27652 – cri-o: Default inheritable capabilities for linux container should be empty
https://notcve.org/view.php?id=CVE-2022-27652
A flaw was found in cri-o, where containers were incorrectly started with non-empty default permissions. A vulnerability was found in Moby (Docker Engine) where containers started incorrectly with non-empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs. Se ha encontrado un fallo en cri-o, donde los contenedores eran iniciados incorrectamente con permisos por defecto no vacíos. Se ha encontrado una vulnerabilidad en Moby (Docker Engine) donde los contenedores se iniciaban incorrectamente con capacidades de proceso Linux heredables no vacías. • https://bugzilla.redhat.com/show_bug.cgi?id=2066839 https://github.com/cri-o/cri-o/security/advisories/GHSA-4hj2-r2pm-3hc6 https://access.redhat.com/security/cve/CVE-2022-27652 • CWE-276: Incorrect Default Permissions •
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') •
