A flaw was found in podman before 1.7.0. File permissions for non-root
users running in a privileged container are not correctly checked. This
flaw can be abused by a low-privileged user inside the container to access
any other file in the container, even if owned by the root user inside the
container. It does not allow to directly escape the container, though being
a privileged container means that a lot of security features are disabled
when running the container. The highest threat from this vulnerability is
to data confidentiality and integrity as well as system availability.
