CVE-2024-11218 is a high-severity vulnerability in Red Hat Enterprise Linux 10, published on 22 Jan 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link. ### Official description A vulnerability was found in `podman build` and `buildah.` This issue occurs in a container breakout by using --jobs=2 and a race condition when building a malicious Containerfile. SELinux might mitigate it, but even with SELinux on, it still allows the enumeration of files and directories on the host.

Affected packages and fixed versions: - github.com/containers/buildah (Go): affected all versions; fixed in 1.33.12, 1.35.5, 1.37.6, 1.38.1 - github.com/containers/buildah (Go): affected all versions; fixed in 1.33.12 - github.com/containers/buildah (Go): affected all versions; fixed in 1.33.12 - github.com/containers/buildah (Go): affected from 1.35.0; fixed in 1.35.5 - github.com/containers/buildah (Go): affected from 1.35.0; fixed in 1.35.5 - github.com/containers/buildah (Go): affected from 1.37.0; fixed in 1.37.6 - github.com/containers/buildah (Go): affected from 1.37.0; fixed in 1.37.6 - github.com/containers/buildah (Go): affected from 1.38.0; fixed in 1.38.1 - github.com/containers/buildah (Go): affected from 1.38.0; fixed in 1.38.1 Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
