CVE-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 •
CVE-2018-12207 – hw: Machine Check Error on Page Size Change (IFU)
https://notcve.org/view.php?id=CVE-2018-12207
Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. Una invalidación inapropiada de las actualizaciones de la tabla de páginas por parte de un sistema operativo invitado virtual para múltiples procesadores Intel® puede habilitar a un usuario autenticado para permitir potencialmente una denegación de servicio del sistema host por medio de un acceso local. A flaw was found in the way Intel CPUs handle inconsistency between, virtual to physical memory address translations in CPU's local cache and system software's Paging structure entries. A privileged guest user may use this flaw to induce a hardware Machine Check Error on the host processor, resulting in a severe DoS scenario by halting the processor. System software like OS OR Virtual Machine Monitor (VMM) use virtual memory system for storing program instructions and data in memory. Virtual Memory system uses Paging structures like Page Tables and Page Directories to manage system memory. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00042.html https://access.redhat.com/errata/RHSA-2019:3916 https://access.redhat.com/errata/RHSA-2019:3936 https://access.redhat.com/errata/RHSA-2019:3941 https://access.redhat.com/errata/RHSA-2020:0026 https://access.redhat.com/errata/RHSA-2020:0028 https://access.redhat.com/errata/RHSA-2020:0204 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I5WWPW4BSZDDW7VHU427XTVXV7ROOFFW https:/ • CWE-20: Improper Input Validation CWE-226: Sensitive Information in Resource Not Removed Before Reuse •
CVE-2019-10223
https://notcve.org/view.php?id=CVE-2019-10223
A security issue was discovered in the kube-state-metrics versions v1.7.0 and v1.7.1. An experimental feature was added to the v1.7.0 release that enabled annotations to be exposed as metrics. By default, the kube-state-metrics metrics only expose metadata about Secrets. However, a combination of the default `kubectl` behavior and this new feature can cause the entire secret content to end up in metric labels thus inadvertently exposing the secret content in metrics. This feature has been reverted and released as the v1.7.2 release. • http://www.openwall.com/lists/oss-security/2019/08/15/8 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10223 https://github.com/kubernetes/kube-state-metrics/releases/tag/v1.7.2 https://www.openwall.com/lists/oss-security/2019/08/09/1 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2019-14287 – sudo 1.8.27 - Security Bypass
https://notcve.org/view.php?id=CVE-2019-14287
In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u \#$((0xffffffff))" command. En Sudo anteriores a 1.8.28, un atacante con acceso a una cuenta Runas ALL sudoer puede omitir ciertas listas negras de políticas y módulos PAM de sesión, y puede causar un registro incorrecto, mediante la invocación sudo con un ID de usuario creado. Por ejemplo, esto permite la omisión de la configuración root y el registro USER= para un comando "sudo -u \#$((0xffffffff))". • https://www.exploit-db.com/exploits/47502 https://github.com/n0w4n/CVE-2019-14287 https://github.com/shallvhack/Sudo-Security-Bypass-CVE-2019-14287 https://github.com/CMNatic/Dockerized-CVE-2019-14287 https://github.com/axax002/sudo-vulnerability-CVE-2019-14287 https://github.com/N3rdyN3xus/CVE-2019-14287 https://github.com/DewmiApsara/CVE-2019-14287 https://github.com/MariliaMeira/CVE-2019-14287 https://github.com/edsonjt81/CVE-2019-14287- https://github.com/SachinthaDeSilva-cmd& • CWE-267: Privilege Defined With Unsafe Actions CWE-755: Improper Handling of Exceptional Conditions •
CVE-2019-16884 – runc: AppArmor/SELinux bypass with malicious image that specifies a volume at /proc
https://notcve.org/view.php?id=CVE-2019-16884
runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfs_linux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory. runc versiones hasta 1.0.0-rc8, como es usado en Docker versiones hasta 19.03.2-ce y otros productos, permite omitir la restricción de AppArmor porque el archivo libcontainer/rootfs_linux.go comprueba incorrectamente los destinos de montaje y, por lo tanto, una imagen Docker maliciosa puede ser montada sobre un directorio /proc . • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00073.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00010.html https://access.redhat.com/errata/RHSA-2019:3940 https://access.redhat.com/errata/RHSA-2019:4074 https://access.redhat.com/errata/RHSA-2019:4269 https://github.com/opencontainers/runc/issues/2128 https://lists.debian.org/debian-lts-announce/2023/02/msg00016.html https: • CWE-41: Improper Resolution of Path Equivalence CWE-863: Incorrect Authorization •
