package, as well as bug fixes to the compiler, the go command, the runtime,
and the crypto/tls, go/types, net/http, and path/filepath packages. See the

From the security mailing:
[security] Go 1.21.1 and Go 1.20.8 are released
Hello gophers,
We have just released Go versions 1.21.1 and 1.20.8, minor point releases.
These minor releases include 4 security fixes following the security policy:
- cmd/go: go.mod toolchain directive allows arbitrary execution
The go.mod toolchain directive, introduced in Go 1.21, could be leveraged to
execute scripts and binaries relative to the root of the module when the "go"
command was executed within the module. This applies to modules downloaded using
the "go" command from the module proxy, as well as modules downloaded directly
using VCS software.
Thanks to Juho Nurminen of Mattermost for reporting this issue.
This is CVE-2023-39320 and Go issue https://go.dev/issue/62198.
- html/template: improper handling of HTML-like comments within script contexts
The html/template package did not properly handle HMTL-like "<!--" and "-->"
comment tokens, nor hashbang "#!" comment tokens, in <script> contexts. This may
cause the template parser to improperly interpret the contents of <script>
contexts, causing actions to be improperly escaped. This could be leveraged to
perform an XSS attack.
Thanks to Takeshi Kaneko (GMO Cybersecurity by Ierae, Inc.) for reporting this
issue.
This is CVE-2023-39318 and Go issue https://go.dev/issue/62196.
- html/template: improper handling of special tags within script contexts
The html/template package did not apply the proper rules for handling occurrences
of "<script", "<!--", and "</script" within JS literals in <script> contexts.
This may cause the template parser to improperly consider script contexts to be
terminated early, causing actions to be improperly escaped. This could be
leveraged to perform an XSS attack.
Thanks to Takeshi Kaneko (GMO Cybersecurity by Ierae, Inc.) for reporting this
issue.
This is CVE-2023-39319 and Go issue https://go.dev/issue/62197.
- crypto/tls: panic when processing post-handshake message on QUIC connections
Processing an incomplete post-handshake message for a QUIC connection caused a panic.
Thanks to Marten Seemann for reporting this issue.
This is CVE-2023-39321 and CVE-2023-39322 and Go issue https://go.dev/issue/62266.

Distribution
The Docker toolset to pack, ship, store, and deliver content.
This repository provides the Docker Registry 2.0 implementation for storing and distributing Docker images. It supersedes the docker/docker-registry project with a new API design, focused around security and performance.
This repository contains the following components:
| Component | Description |
|---|---|
| registry | An implementation of the Docker Registry HTTP API V2 for use with docker 1.6+. |
| libraries | A rich set of libraries for interacting with distribution components. Please see godoc for details. Note: These libraries are unstable. |
| specifications | Distribution related specifications are available in docs/spec |
| documentation | Docker's full documentation set is available at docs.docker.com. This repository contains the subset related just to the registry. |
How does this integrate with Docker engine?
This project should provide an implementation to a V2 API for use in the Docker
core project. The API should be embeddable
and simplify the process of securely pulling and pushing content from docker
daemons.
What are the long term goals of the Distribution project?
The Distribution project has the further long term goal of providing a secure tool chain for distributing content. The specifications, APIs and tools should be as useful with Docker as they are without.
Our goal is to design a professional grade and extensible content distribution system that allow users to:
- Enjoy an efficient, secured and reliable way to store, manage, package and exchange content
- Hack/roll their own on top of healthy open-source components
- Implement their own home made solution through good specs, and solid extensions mechanism.
More about Registry 2.0
The new registry implementation provides the following benefits:
- faster push and pull
- new, more efficient implementation
- simplified deployment
- pluggable storage backend
- webhook notifications
For information on upcoming functionality, please see ROADMAP.md.
Who needs to deploy a registry?
By default, Docker users pull images from Docker's public registry instance. Installing Docker gives users this ability. Users can also push images to a repository on Docker's public registry, if they have a Docker Hub account.
For some users and even companies, this default behavior is sufficient. For others, it is not.
For example, users with their own software products may want to maintain a registry for private, company images. Also, you may wish to deploy your own image repository for images used to test or in continuous integration. For these use cases and others, deploying your own registry instance may be the better choice.
Migration to Registry 2.0
For those who have previously deployed their own registry based on the Registry 1.0 implementation and wish to deploy a Registry 2.0 while retaining images, data migration is required. A tool to assist with migration efforts has been created. For more information see docker/migrator.
