CVE-2020-8945 – proglottis/gpgme: Use-after-free in GPGME bindings during container image pull
https://notcve.org/view.php?id=CVE-2020-8945
The proglottis Go wrapper before 0.1.1 for the GPGME library has a use-after-free, as demonstrated by use for container image pulls by Docker or CRI-O. This leads to a crash or potential code execution during GPG signature verification. El contenedor Proglottis Go versiones anteriores a 0.1.1 para la biblioteca GPGME, presenta un uso de la memoria previamente liberada, como es demostrado por el uso para las extracciones de imágenes de contenedores para Docker o CRI-O. Esto conlleva a un bloqueo o posible ejecución de código durante una comprobación de la firma GPG. A use-after-free vulnerability was found in the Go GPGME wrapper library, github.com/proglottis/gpgme. • https://access.redhat.com/errata/RHSA-2020:0679 https://access.redhat.com/errata/RHSA-2020:0689 https://access.redhat.com/errata/RHSA-2020:0697 https://bugzilla.redhat.com/show_bug.cgi?id=1795838 https://github.com/containers/image/commit/4c7a23f82ef09127b0ff28366d1cf31316dd6cc1 https://github.com/proglottis/gpgme/compare/v0.1.0...v0.1.1 https://github.com/proglottis/gpgme/pull/23 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3SOCLOPTSYABTE4CLTSPDIF • CWE-416: Use After Free •
CVE-2019-19921 – runc: volume mount race condition with shared mounts leads to information leak/integrity manipulation
https://notcve.org/view.php?id=CVE-2019-19921
runc through 1.0.0-rc9 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. (This vulnerability does not affect Docker due to an implementation detail that happens to block the attack.) runc versiones hasta 1.0.0-rc9, posee un Control de Acceso Incorrecto conllevando a una escalada de privilegios, relacionado con el archivo libcontainer/rootfs_linux.go. Para explotar esto, un atacante debe ser capaz de generar dos contenedores con configuraciones de montaje de volumen personalizadas y ser capaz de ejecutar imágenes personalizadas. (Esta vulnerabilidad no afecta a Docker debido a un detalle de implementación que bloquea el ataque). • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00018.html https://access.redhat.com/errata/RHSA-2020:0688 https://access.redhat.com/errata/RHSA-2020:0695 https://github.com/opencontainers/runc/issues/2197 https://github.com/opencontainers/runc/pull/2190 https://github.com/opencontainers/runc/releases https://lists.debian.org/debian-lts-announce/2023/03/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ANUGDBJ7NBUMSUFZUSKU3ZMQYZ2Z3S • CWE-41: Improper Resolution of Path Equivalence CWE-706: Use of Incorrectly-Resolved Name or Reference •
CVE-2020-1726 – podman: incorrectly allows existing files in volumes to be overwritten by a container when it is created
https://notcve.org/view.php?id=CVE-2020-1726
A flaw was discovered in Podman where it incorrectly allows containers when created to overwrite existing files in volumes, even if they are mounted as read-only. When a user runs a malicious container or a container based on a malicious image with an attached volume that is used for the first time, it is possible to trigger the flaw and overwrite files in the volume.This issue was introduced in version 1.6.0. Se detectó un fallo en Podman donde permite incorrectamente que los contenedores cuando se crean sobrescriban los archivos existentes en volúmenes, incluso si están montados como de solo lectura. Cuando un usuario ejecuta un contenedor malicioso o un contenedor basado en una imagen maliciosa con un volumen adjunto que se usa por primera vez, es posible desencadenar el fallo y sobrescribir archivos en el volumen. Este problema fue introducido en la versión 1.6.0. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00097.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00103.html https://access.redhat.com/errata/RHSA-2020:0680 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1726 https://access.redhat.com/security/cve/CVE-2020-1726 https://bugzilla.redhat.com/show_bug.cgi?id=1801152 • CWE-552: Files or Directories Accessible to External Parties •
CVE-2020-1708 – openshift/mysql-apb: /etc/passwd is given incorrect privileges
https://notcve.org/view.php?id=CVE-2020-1708
It has been found in openshift-enterprise version 3.11 and all openshift-enterprise versions from 4.1 to, including 4.3, that multiple containers modify the permissions of /etc/passwd to make them modifiable by users other than root. An attacker with access to the running container can exploit this to modify /etc/passwd to add a user and escalate their privileges. This CVE is specific to the openshift/mysql-apb. Se ha encontrado en openshift-enterprise versión 3.11 y en todas las versiones de openshift-enterprise desde 4.1 hasta, 4.3 incluyéndola, que varios contenedores modifican los permisos de /etc/passwd para que otros usuarios diferentes de root puedan modificarlos. Un atacante con acceso al contenedor en ejecución puede explotar esto para modificar /etc/passwd para agregar un usuario y escalar sus privilegios. • https://access.redhat.com/errata/RHSA-2020:0617 https://access.redhat.com/errata/RHSA-2020:0681 https://access.redhat.com/errata/RHSA-2020:0694 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1708 https://access.redhat.com/security/cve/CVE-2020-1708 https://bugzilla.redhat.com/show_bug.cgi?id=1793299 https://access.redhat.com/articles/4859371 • CWE-266: Incorrect Privilege Assignment CWE-269: Improper Privilege Management •
CVE-2020-1712 – systemd: use-after-free when asynchronous polkit queries are performed
