AI-suggested

SELinux mandatory access controls should be enabled and properly configured to confine the build process (e.g., Podman) to specific domains such as container_t. This limits unauthorized access to sensitive host files and directories. Users should ensure SELinux is active and enforcing on systems running podman build or buildah. Additionally, avoid running the build process as a root-owned system service accessible to unprivileged users. Monitor vendor advisories for official patches or updates addressing this vulnerability.

Description

CVE-2024-11218 is a high-severity vulnerability in podman build and buildah that allows container breakout via a race condition triggered by using --jobs=2 when building a malicious Containerfile. The vulnerability enables unauthorized read/write access to the host filesystem by exploiting the --mount flag in RUN instructions. SELinux can mitigate the risk by confining the build process, but even with SELinux enabled, attackers may still enumerate files and directories on the host.
