CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 1CVE-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 •
CVSS: 4.9EPSS: 0%CPEs: 2EXPL: 0CVE-2022-0532 – cri-o: pod with access to 'hostIPC' and 'hostNetwork' kernel namespace allows sysctl from the list of safe sysctls to be applied to the host
https://notcve.org/view.php?id=CVE-2022-0532
An incorrect sysctls validation vulnerability was found in CRI-O 1.18 and earlier. The sysctls from the list of "safe" sysctls specified for the cluster will be applied to the host if an attacker is able to create a pod with a hostIPC and hostNetwork kernel namespace. Se ha encontrado una vulnerabilidad de comprobación incorrecta de sysctls en CRI-O versiones 1.18 y anteriores. Las sysctls de la lista de sysctls "safe" especificadas para el cluster serán aplicadas al host si un atacante es capaz de crear un pod con un espacio de nombres del kernel hostIPC y hostNetwork An incorrect sysctls validation vulnerability was found in CRI-O. The sysctls from the list of "safe" sysctls specified for the cluster [0] will be applied to the host if an attacker can create a pod with a `hostIPC` and `hostNetwork` kernel namespace. • https://bugzilla.redhat.com/show_bug.cgi?id=2051730 https://kubernetes.io/docs/tasks/administer-cluster/sysctl-cluster/#enabling-unsafe-sysctls https://access.redhat.com/security/cve/CVE-2022-0532 • CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 6.0EPSS: 0%CPEs: 5EXPL: 0CVE-2019-14891 – cri-o: infra container reparented to systemd following OOM Killer killing it's conmon
https://notcve.org/view.php?id=CVE-2019-14891
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. Se encontró un fallo en cri-o, como un resultado de que todos los procesos relacionados con pod están colocados en el mismo grupo de memoria. Esto puede resultar en que se eliminen los procesos de administración de contenedores (conmon) si un proceso de carga de trabajo desencadena una condición de falta de memoria (OOM) para el cgroup. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14891 https://access.redhat.com/security/cve/CVE-2019-14891 https://bugzilla.redhat.com/show_bug.cgi?id=1772280 • CWE-460: Improper Cleanup on Thrown Exception CWE-754: Improper Check for Unusual or Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2018-1000400
Kubernetes CRI-O version prior to 1.9 contains a Privilege Context Switching Error (CWE-270) vulnerability in the handling of ambient capabilities that can result in containers running with elevated privileges, allowing users abilities they should not have. This attack appears to be exploitable via container execution. This vulnerability appears to have been fixed in 1.9. Kubernetes CRI-O, en versiones anteriores a la 1.9, contiene una vulnerabilidad de error de switching en un contexto privilegiado (CWE-270) en la gestión de capacidades de ambiente que puede resultar en que los contenedores se ejecuten con privilegios elevados, lo que permite que los usuarios tengan permisos que no deberían tener. Este ataque parece ser explotable mediante la ejecución de contenedores. • http://www.securityfocus.com/bid/104262 https://github.com/kubernetes-incubator/cri-o/pull/1558/files • CWE-269: Improper Privilege Management •
