How to Fix CVE-2024-23653

To remediate this vulnerability, upgrade all affected Github.com/moby/buildkit dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/moby/buildkit fixed: 0.12.5 
Upgrade github.com/moby/buildkit to 0.12.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/moby/buildkit

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-23653, inspect your project dependencies for Github.com/moby/buildkit:

inspect dependencies for github.com/moby/buildkit

Analyze the terminal output to locate any version of Github.com/moby/buildkit in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.12.5), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. In Github.com/moby/buildkit, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact In addition to running containers as build steps, BuildKit also provides APIs for running interactive containers based on built images. It was possible to use these APIs to ask BuildKit to run a container with elevated privileges. Normally, running such containers is only allowed if special `security.insecure` entitlement is enabled both by buildkitd configuration and allowed by the user initializing the build request. ### Patches The issue has been fixed in v0.12.5 . ### Workarounds Avoid using BuildKit frontends from untrusted sources. A frontend image is usually specified as the `#syntax` line on your Dockerfile, or with `--frontend` flag when using `buildctl build` command. ### References
