Description
This security bulletin contains information about 6 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) Improper Privilege Management (CVE-ID: CVE-2024-1753)
The vulnerability allows a remote attacker to escalate privileges.
The vulnerability exists due to the affected application allows containers to mount arbitrary locations on the host filesystem into build containers. A remote attacker can escalate privileges.
3) Input validation error (CVE-ID: CVE-2024-9341)
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied input. When FIPS mode is enabled on a system, container runtimes may incorrectly handle certain file paths due to improper validation in the containers/common Go library. This flaw allows an attacker to exploit symbolic links and trick the system into mounting sensitive host directories inside a container.
4) 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.
5) Path traversal (CVE-ID: CVE-2024-9675)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to input validation error when processing directory traversal sequences in cache mounts. A local user can execute a 'RUN' instruction in a Container file to mount an arbitrary directory from the host into the container as long as those files can be accessed by the user running Buildah.
6) UNIX symbolic link following (CVE-ID: CVE-2024-9676)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a symlink following issue when running a malicious image using an automatically assigned user namespace (`--userns=auto` in Podman and Buildah). A local user can create a symbolic link to an arbitrary file on the system, force the library to read it and perform a denial of service (DoS) attack.
