CVE-2024-23651

BuildKit is a toolkit for converting source code to build artifacts in an
efficient, expressive and repeatable manner. 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. The issue has been fixed in v0.12.5.
Workarounds include, avoiding using BuildKit frontend from an untrusted
source or building an untrusted Dockerfile containing cache mounts with
–mount=type=cache,source=… options.
