Release notes

Sourced from github.com/moby/moby's releases.

v20.10.20

This release of Docker Engine contains partial mitigations for a Git vulnerability (CVE-2022-39253), and has updated handling of image:tag@digest image references.

The Git vulnerability allows a maliciously crafted Git repository, when used as a build context, to copy arbitrary filesystem paths into resulting containers/images; this can occur in both the daemon, and in API clients, depending on the versions and tools in use.

The mitigations available in this release and in other consumers of the daemon API are partial and only protect users who build a Git URL context (e.g. git+protocol://). As the vulnerability could still be exploited by manually run Git commands that interact with and check out submodules, users should immediately upgrade to a patched version of Git to protect against this vulernability. Further details are available from the GitHub blog ("Git security vulnerabilities announced").

Client

• Added a mitigation for CVE-2022-39253, when using the classic Builder with a Git URL as the build context.

Daemon

• Updated handling of image:tag@digest references. When pulling an image using the image:tag@digest ("pull by digest"), image resolution happens through the content-addressable digest and the image and tag are not used. While this is expected, this could lead to confusing behavior, and could potentially be exploited through social engineering to run an image that is already present in the local image store. Docker now checks if the digest matches the repository name used to pull the image, and otherwise will produce an error.

Builder

• Updated handling of image:tag@digest references. Refer to the "Daemon" section above for details.
• Added a mitigation to the classic Builder and updated BuildKit to v0.8.3-31-gc0149372, for CVE-2022-39253.

v20.10.19

This release of Docker Engine comes with some bug-fixes, and an updated version of Docker Compose.

Builder

• Fix an issue that could result in a panic during docker builder prune or docker system prune moby/moby#44122.

Daemon
