Summary
BuildKit has a possible runtime DoS via unbounded group parsing
Details

Impact

Maliciously crafted base image or build can cause a Denial of Service (DoS) condition. When creating a container from this image, memory exhaustion occurs, leading to an Out Of Memory (OOM) kill of the buildkitd process.

Patches

Issue is fixed in BuildKit v0.31.1+

Workarounds

Use trusted build sources.
