From the mailing list:
We have just released Go versions 1.19.2 and 1.18.7, minor point releases.
These minor releases include 3 security fixes following the security policy:
- archive/tar: unbounded memory consumption when reading headers
Reader.Read did not set a limit on the maximum size of file headers.
A maliciously crafted archive could cause Read to allocate unbounded
amounts of memory, potentially causing resource exhaustion or panics.
Reader.Read now limits the maximum size of header blocks to 1 MiB.
Thanks to Adam Korczynski (ADA Logics) and OSS-Fuzz for reporting this issue.
This is CVE-2022-2879 and Go issue https://go.dev/issue/54853.
- net/http/httputil: ReverseProxy should not forward unparseable query parameters
Requests forwarded by ReverseProxy included the raw query parameters from the
inbound request, including unparseable parameters rejected by net/http. This
could permit query parameter smuggling when a Go proxy forwards a parameter
with an unparseable value.
ReverseProxy will now sanitize the query parameters in the forwarded query
when the outbound request's Form field is set after the ReverseProxy.Director
function returns, indicating that the proxy has parsed the query parameters.
Proxies which do not parse query parameters continue to forward the original
query parameters unchanged.
Thanks to Gal Goldstein (Security Researcher, Oxeye) and
Daniel Abeles (Head of Research, Oxeye) for reporting this issue.
This is CVE-2022-2880 and Go issue https://go.dev/issue/54663.
- regexp/syntax: limit memory used by parsing regexps
The parsed regexp representation is linear in the size of the input,
but in some cases the constant factor can be as high as 40,000,
making relatively small regexps consume much larger amounts of memory.
Each regexp being parsed is now limited to a 256 MB memory footprint.
Regular expressions whose representation would use more space than that
are now rejected. Normal use of regular expressions is unaffected.
Thanks to Adam Korczynski (ADA Logics) and OSS-Fuzz for reporting this issue.
This is CVE-2022-41715 and Go issue https://go.dev/issue/55949.

The Moby Project
Moby is an open-source project created by Docker to enable and accelerate software containerization.
It provides a "Lego set" of toolkit components, the framework for assembling them into custom container-based systems, and a place for all container enthusiasts and professionals to experiment and exchange ideas. Components include container build tools, a container registry, orchestration tools, a runtime and more, and these can be used as building blocks in conjunction with other tools and projects.
Principles
Moby is an open project guided by strong principles, aiming to be modular, flexible and without too strong an opinion on user experience. It is open to the community to help set its direction.
- Modular: the project includes lots of components that have well-defined functions and APIs that work together.
- Batteries included but swappable: Moby includes enough components to build fully featured container system, but its modular architecture ensures that most of the components can be swapped by different implementations.
- Usable security: Moby provides secure defaults without compromising usability.
- Developer focused: The APIs are intended to be functional and useful to build powerful tools. They are not necessarily intended as end user tools but as components aimed at developers. Documentation and UX is aimed at developers not end users.
Audience
The Moby Project is intended for engineers, integrators and enthusiasts looking to modify, hack, fix, experiment, invent and build systems based on containers. It is not for people looking for a commercially supported system, but for people who want to work and learn with open source code.
Relationship with Docker
The components and tools in the Moby Project are initially the open source components that Docker and the community have built for the Docker Project. New projects can be added if they fit with the community goals. Docker is committed to using Moby as the upstream for the Docker Product. However, other projects are also encouraged to use Moby as an upstream, and to reuse the components in diverse ways, and all these uses will be treated in the same way. External maintainers and contributors are welcomed.
The Moby project is not intended as a location for support or feature requests for Docker products, but as a place for contributors to work on open source code, fix bugs, and make the code more useful. The releases are supported by the maintainers, community and users, on a best efforts basis only, and are not intended for customers who want enterprise or commercial support; Docker EE is the appropriate product for these use cases.
