GitHub Vulnerability Alerts

CVE-2024-23653

Impact

In addition to running containers as build steps, BuildKit also provides APIs for running interactive containers based on built images. It was possible to use these APIs to ask BuildKit to run a container with elevated privileges. Normally, running such containers is only allowed if special security.insecure entitlement is enabled both by buildkitd configuration and allowed by the user initializing the build request.

Patches

The issue has been fixed in v0.12.5 .

Workarounds

Avoid using BuildKit frontends from untrusted sources. A frontend image is usually specified as the #syntax line on your Dockerfile, or with --frontend flag when using buildctl build command.

CVE-2024-23652

Impact

A malicious BuildKit frontend or Dockerfile using RUN --mount could trick the feature that removes empty files created for the mountpoints into removing a file outside the container, from the host system.

Patches

The issue has been fixed in v0.12.5

Workarounds

Avoid using BuildKit frontend from an untrusted source or building an untrusted Dockerfile containing RUN --mount feature.

References

CVE-2024-23651

Impact

Two malicious build steps running in parallel sharing the same cache mounts with subpaths could cause a race condition that can lead to files from the host system being accessible to the build container.

Patches

The issue has been fixed in v0.12.5

Workarounds

Avoid using BuildKit frontend from an untrusted source or building an untrusted Dockerfile containing cache mounts with --mount=type=cache,source=... options.
