Summary

### 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. ### Workarounds There is no way to work around this issue without patching. ### References Due to an oversight in the OCI Image Specification 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. ### For more information If you have any questions or comments about this advisory: * Open an issue in distribution * Open an issue in distribution-spec * Email us at cncf-distribution-security@lists.cncf.io
