go1.20.10 (released 2023-10-10) includes a security fix to the net/http package. See the Go 1.20.10 milestone on our issue tracker for details: https://github.com/golang/go/issues?q=milestone%3AGo1.20.10+label%3ACherryPickApproved full diff: https://github.com/golang/go/compare/go1.20.9...go1.20.10 From the security mailing: [security] Go 1.21.3 and Go 1.20.10 are released Hello gophers, We have just released Go versions 1.21.3 and 1.20.10, minor point releases. These minor releases include 1 security fixes following the security policy: - net/http: rapid stream resets can cause excessive work A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded to the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit. New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 v0.17.0, for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams setting and the ConfigureServer function. This is CVE-2023-39325 and Go issue https://go.dev/issue/63417. This is also tracked by CVE-2023-44487. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
The toolset to pack, ship, store, and deliver content.
This repository's main product is the Open Source Registry implementation for storing and distributing container images and other content using the OCI Distribution Specification. The goal of this project is to provide a simple, secure, and scalable base for building a large scale registry solution or running a simple private registry. It is a core library for many registry operators including Docker Hub, GitHub Container Registry, GitLab Container Registry and DigitalOcean Container Registry, as well as the CNCF Harbor Project, and VMware Harbor Registry.
This repository contains the following components:
| Component | Description |
|---|---|
| registry | An implementation of the OCI Distribution Specification. |
| libraries | A rich set of libraries for interacting with distribution components. Please see godoc for details. Note: The interfaces for these libraries are unstable. |
| 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, containerd, and other OCI client?
Clients implement against the OCI specification and communicate with the registry using HTTP. This project contains a client implementation which is currently in use by Docker, however, it is deprecated for the implementation in containerd and will not support new features.
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.
Contribution
Please see CONTRIBUTING.md for details on how to contribute issues, fixes, and patches to this project. If you are contributing code, see the instructions for building a development environment.
Communication
For async communication and long running discussions please use issues and pull requests on the github repo. This will be the best place to discuss design and implementation.
For sync communication we have a #distribution channel in the CNCF Slack that everyone is welcome to join and chat about development.
