CVE-2022-27649 – podman: Default inheritable capabilities for linux container should be empty
https://notcve.org/view.php?id=CVE-2022-27649
A flaw was found in Podman, where containers were started incorrectly 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 ha encontrado un fallo en Podman, donde los contenedores eran iniciados incorrectamente con permisos por defecto no vacíos.
