Low severity vulnerability was found in gomod github.com/opencontainers/distribution-spec (go) .
In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone was used to determine the type of document during push and pull operations. Documents that contain both “manifests” and “layers” fields could be interpreted as either a manifest or an index in the absence of an accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a client may interpret the resulting content differently.
The OCI Distribution Specification will be updated to require that a
mediaType value present in a manifest or index match the Content-Type header used during the push and pull operations.
Clients pulling from a registry may distrust the Content-Type header and reject an ambiguous document that contains both “manifests” and “layers” fields or “manifests” and “config” fields.
