Official description

A flaw was found in Red Hat Quay's container image upload process. An authenticated user with push access to any repository on the registry can interfere with image uploads in progress by other users, including those in repositories they do not have access to. This could allow the attacker to read, modify, or cancel another user's in-progress image upload.
