# container: digest pulls can be served a different image

When a pull is made by digest, an attacker who controls the registry, a mirror, or the network path can serve other image content, so the user runs an image other than the one they pinned. The fix compares the returned digest to the pinned digest, fails on a mismatch, and verifies manifest and blob hashes when they are fetched.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the installed `container` version is below `1.6.0`.
- Check whether the installed `containerization` version is below `0.52.1`.
- The sources do not give a command for reading these versions.

## Fix

- Upgrade `container` to `1.6.0` or later.
- Upgrade `containerization` to `0.52.1` or later.

## From the sources

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.
