CVSS: 5.8EPSS: 0%CPEs: 1EXPL: 1CVE-2019-18466 – podman: resolving symlink in host filesystem leads to unexpected results of copy operation
https://notcve.org/view.php?id=CVE-2019-18466
An issue was discovered in Podman in libpod before 1.6.0. It resolves a symlink in the host context during a copy operation from the container to the host, because an undesired glob operation occurs. An attacker could create a container image containing particular symlinks that, when copied by a victim user to the host filesystem, may overwrite existing files with others from the host. Se descubrió un problema en Podman en libpod versiones anteriores a la versión 1.6.0. Resuelve un enlace simbólico (symlink) en el contexto del host durante una operación de copia desde el contenedor hacia el host, porque se produce una operación glob no deseada. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00040.html https://access.redhat.com/errata/RHSA-2019:4269 https://bugzilla.redhat.com/show_bug.cgi?id=1744588 https://github.com/containers/libpod/commit/5c09c4d2947a759724f9d5aef6bac04317e03f7e https://github.com/containers/libpod/compare/v1.5.1...v1.6.0 https://github.com/containers/libpod/issues/3829 https://access.redhat.com/security/cve/CVE-2019-18466 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

https://notcve.org/view.php?id=CVE-2019-10152
A path traversal vulnerability has been discovered in podman before version 1.4.0 in the way it handles symlinks inside containers. An attacker who has compromised an existing container can cause arbitrary files on the host filesystem to be read/written when an administrator tries to copy a file from/to the container. Se detectó una vulnerabilidad de salto de ruta (path) en podman anterior a versión 1.4.0, en la manera en que se manejan los enlaces simbólicos dentro de los contenedores. Un atacante que ha comprometido un contenedor existente puede causar que se lean/escriban archivos arbitrarios en el sistema de archivos del host cuando un administrador intenta copiar un archivo desde y hacia el contenedor.

https://notcve.org/view.php?id=CVE-2018-10856
It has been discovered that podman before version 0.6.1 does not drop capabilities when executing a container as a non-root user. This results in unnecessary privileges being granted to the container. Se ha descubierto que podman en versiones anteriores a la 0.6.1 no deja capacidades cuando ejecuta un contenedor como usuario no-root.
