Details

As written in the advisory (Markdown source, shown as plain text).

### 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. ### References https://www.openwall.com/lists/oss-security/2019/05/28/1
