## Overview

### Impact
A custom frontend could send a crafted build request that disabled Seccomp and AppArmor protections for the build container, even if the user did not explicitly allow the `security.insecure` entitlement. Other security measures, like Linux capabilities were still applied to these containers.

### Patches
Problem has been fixed in versions v0.31.1+

### Workarounds
Only use BuildKit frontends from trusted providers.

## Affected packages

- `github.com/moby/buildkit < 0.31.1`

## Remediation

Upgrade to a patched release:

- `github.com/moby/buildkit 0.31.1`
