Overview
Affected versions of this package are vulnerable to Improper Authorization. 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 within it, even if owned by the root user inside the same 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 it. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
