## Overview

### Impact

Systems that rely on digest equivalence for image attestations may be vulnerable to type confusion.

### Patches

Upgrade to at least `v2.8.0-beta.1`  if you are running `v2.x` release. If you use the code from the `main` branch, update at least to the commit after [b59a6f827947f9e0e67df0cfb571046de4733586](https://github.com/distribution/distribution/commit/b59a6f827947f9e0e67df0cfb571046de4733586).

### Workarounds

There is no way to work around this issue without patching.

### References

Due to [an oversight in the OCI Image Specification](https://github.com/opencontainers/image-spec/pull/411) that removed the embedded `mediaType` field from manifests, a maliciously crafted OCI Container Image can cause registry clients to parse the same image in two different ways without modifying the image’s digest by modifying the `Content-Type` header returned by a registry. This can invalidate a common pattern of relying on container image digests for equivalence.
