📋 Description

Impact

In the OCI Image Specification version 1.0.1 and prior, manifest and index documents are not self-describing and documents with a single digest could be interpreted as either a manifest or an index.

Patches

The Image Specification will be updated to recommend that both manifest and index documents contain a mediaType field to identify the type of document. Release v1.0.2 includes these updates.

Workarounds

Software attempting to deserialize an ambiguous document may reject the document if it contains both “manifests” and “layers” fields or “manifests” and “config” fields.
