Doc Text:	A vulnerability exists in the bind-propagation option of the Dockerfile RUN --mount instruction. The system does not properly validate the input passed to this option, allowing users to pass arbitrary parameters to the mount instruction. This issue can be exploited to mount sensitive directories from the host into a container during the build process and, in some cases, modify the contents of those mounted files. Even if SELinux is used, this vulnerability can bypass its protection by allowing the source directory to be relabeled to give the container access to host files.	Story Points:	---

Description OSIDB Bzimport 2024-10-01 10:55:17 UTC

A flaw in the bind-propagation option of the Dockerfile RUN --mount instruction allows arbitrary parameters to be passed to the underlying mount command. This issue enables an attacker to mount arbitrary host files into a container during the build process and potentially modify them. SELinux does not provide sufficient defense, as the attacker can specify :z or :Z to relabel the host directory for container access. The vulnerability requires an attacker to have build privileges on the system and can lead to unauthorized access and modification of host files, posing significant security risks.
