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.
