CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2022-27650 – crun: Default inheritable capabilities for linux container should be empty
https://notcve.org/view.php?id=CVE-2022-27650
A flaw was found in crun where containers were incorrectly started with non-empty default permissions. A vulnerability was found in Moby (Docker Engine) where containers were 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 encontró un fallo en crun donde los contenedores eran iniciados incorrectamente con permisos por defecto no vacíos. Se ha encontrado una vulnerabilidad en Moby (Docker Engine) donde los contenedores eran iniciados incorrectamente con capacidades de proceso Linux heredables no vacías. • https://bugzilla.redhat.com/show_bug.cgi?id=2066845 https://github.com/containers/crun/commit/1aeeed2e4fdeffb4875c0d0b439915894594c8c6 https://github.com/containers/crun/security/advisories/GHSA-wr4f-w546-m398 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HYIGABCZ7ZHAG2XCOGITTQRJU2ASWMFA https://access.redhat.com/security/cve/CVE-2022-27650 • CWE-276: Incorrect Default Permissions •

https://notcve.org/view.php?id=CVE-2019-18837
An issue was discovered in crun before 0.10.5. With a crafted image, it doesn't correctly check whether a target is a symlink, resulting in access to files outside of the container. This occurs in libcrun/linux.c and libcrun/chroot_realpath.c. Se descubrió un problema en crun versiones anteriores a la versión 0.10.5. Con una imagen especialmente diseñada, no comprueba correctamente si un objetivo es un enlace simbólico, resultando en el acceso a archivos fuera del contenedor. • https://github.com/containers/crun/pull/173 https://github.com/containers/crun/releases/tag/0.10.5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DTA5SJUAKQUK6HRY2CZVJUIZP5BO3EOG https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ITB2UNEGHXZUR3ATYHWPSK5LJB36N7AP • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
