QID 980027: Go (go) Security Update for github.com/opencontainers/distribution-spec (GHSA-mc8v-mgrf-8f4m)

Security update has been released for github.com/opencontainers/distribution-spec to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

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.

  • CVSS V3 rated as Medium - 5 severity.
  • CVSS V2 rated as Medium - 4 severity.
    • Solution
    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.Workaround:
    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.
