Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Go client in github.com/docker/distribution (versions up to and including 2.8.3, with no fixed version listed) does not check that the manifest returned by manifests.Get() matches the digest the caller requested. An attacker who controls or can intercept the registry connection can substitute a different manifest, and the client returns it without warning. Upgrade github.com/distribution/distribution/v3 to version 3.1.2 or later, which fixes this issue; no fix is listed for github.com/docker/distribution.
