CVE-2024-9407

Summary

CVE-2024-9407 is a newly discovered vulnerability affecting the Dockerfile RUN --mount instruction's bind-propagation option. This issue arises due to insufficient input validation, allowing users to pass arbitrary parameters during the container build process. The consequence of this vulnerability is the ability to mount sensitive directories from the host into the container, potentially leading to file modification. Even with SELinux implementation, this vulnerability can bypass its protection by enabling the source directory to be relabeled, granting container access to host files.
