github.com/moby/buildkit is vulnerable to Denial of Service (DoS)
35
Low Risk
This Affects:
github.com/moby/buildkitTL;DR
BuildKit parses image group definitions without bounding the amount of work or memory involved. A maliciously crafted base image or build can drive unbounded group parsing when a container is created from the image. Memory exhaustion follows, triggering an out-of-memory kill of the buildkitd process and a denial of service. The fix bounds group parsing to prevent excessive resource use.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you build from untrusted base images or build definitions.

github.com/moby/buildkit is vulnerable to Denial of Service (DoS) in versions 0.0.1 - 0.31.0.
