Medium 5.6
In plain English
A medium-severity security flaw in container from Apple. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.1% (higher than 1% of all known vulnerabilities).
Official description
An attacker who controls the registry, a mirror, or the network path to it may be able to serve arbitrary image content in response to a pull by digest, so that a user runs an image other than the one they pinned. The fix compares the returned digest to the pinned digest and fails the pull on a mismatch. Tag pulls are exempt, because a tag is mutable by design. The fix also verifies the hash of manifests and blobs when they are fetched. This vulnerability is addressed in container version 1.6.0 and containerization version 0.52.1.
