Description
This security bulletin contains information about 2 secuirty vulnerabilities.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-11218)
The vulnerability allows a remote user to escalate privileges on the system.
The vulnerability exists due to improperly imposed security restrictions during the build process. A remote user can leverage usage of a --mount flag in RUN instructions in Containerfiles along with multi-stage builds with use of concurrently-executing build stages or multiple separate but concurrently-executing builds to expose content from the build host and perform read/write operations on the system with privileges of the podman system service.
2) Input validation error (CVE-ID: CVE-2024-9407)
The vulnerability allows a remote user to gain access to sensitive information.
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.
