How to fix?

github.com/hpcng/singularity/internal/pkg/build is an application containers for Linux.
Affected versions of this package are vulnerable to Insecure Permissions. When a command that results in a container build operation is executed, it is possible for a user with access to the system to read the contents of the image during the build. Additionally, if the image contains a world-writable file or directory, it is possible for a user to inject arbitrary content into the running build, which in certain circumstances may enable arbitrary code execution during the build and/or when the built container is run.
