On Windows, syscall.StartProcess and os/exec.Cmd did not properly
check for invalid environment variable values. A malicious
environment variable value could exploit this behavior to set a
value for a different environment variable. For example, the
environment variable string "A=B\x00C=D" set the variables "A=B" and
"C=D".

This is CVE-2022-41716 and Go issue https://go.dev/issue/56284.
This Go release also fixes https://github.com/golang/go/issues/56309, a
runtime bug which can cause random memory corruption when a goroutine
exits with runtime.LockOSThread() set. This fix is necessary to unblock
work to replace certain uses of pkg/reexec with unshared OS threads.

Setting cmd.Env overrides the default of passing through the parent
process' environment, which works out fine most of the time, except when
it doesn't. For whatever reason, leaving out all the environment causes
git-for-windows sh.exe subprocesses to enter an infinite loop of
access violations during Cygwin initialization in certain environments
(specifically, our very own dev container image).

Previously, Docker Hub was excluded when configuring "allow-nondistributable-artifacts".
With the updated policy announced by Microsoft, we can remove this restriction;
https://techcommunity.microsoft.com/t5/containers/announcing-windows-container-base-image-redistribution-rights/ba-p/3645201
There are plans to deprecated support for foreign layers altogether in the OCI,
and we should consider to make this option the default, but as that requires
deprecating the option (and possibly keeping an "opt-out" option), we can look
at that separately.

This is accomplished by storing the distribution source in the content
labels. If the distribution source is not found then we check to the
registry to see if the digest exists in the repo, if it does exist then
the puller will use it.

when the daemon clones a Git repo, it could break workflows if it was

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.

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.

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.

Before this change restarting the daemon in live-restore with running
containers + a restart policy meant that volume refs were not restored.
This specifically happens when the container is still running *and*
there is a restart policy that would make sure the container was running
again on restart.
The bug allows volumes to be removed even though containers are
referencing them. 😱

The `docker` CLI currently doesn't handle situations where the current context
(as defined in `~/.docker/config.json`) is invalid or doesn't exist. As loading
(and checking) the context happens during initialization of the CLI, this
prevents `docker context` commands from being used, which makes it complicated
to fix the situation. For example, running `docker context use <correct context>`
would fail, which makes it not possible to update the `~/.docker/config.json`,
unless doing so manually.
For example, given the following `~/.docker/config.json`:
```json
{
"currentContext": "nosuchcontext"
}
```
All of the commands below fail:
```bash
docker context inspect rootless
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
docker context rm --force rootless
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
docker context use default
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
```
While these things should be fixed, this patch updates the script to switch
the context using the `--context` flag; this flag is taken into account when
initializing the CLI, so that having an invalid context configured won't
block `docker context` commands from being executed. Given that all `context`
commands are local operations, "any" context can be used (it doesn't need to
make a connection with the daemon).
With this patch, those commands can now be run (and won't fail for the wrong
reason);
```bash
docker --context=default context inspect -f "{{.Name}}" rootless
rootless
docker --context=default context inspect -f "{{.Name}}" rootless-doesnt-exist
context "rootless-doesnt-exist" does not exist
```
One other issue may also cause things to fail during uninstall; trying to remove
a context that doesn't exist will fail (even with the `-f` / `--force` option
set);
```bash
docker --context=default context rm blablabla
Error: context "blablabla": not found
```
While this is "ok" in most circumstances, it also means that (potentially) the
current context is not reset to "default", so this patch adds an explicit
`docker context use`, as well as unsetting the `DOCKER_HOST` and `DOCKER_CONTEXT`
environment variables.

The OCI image spec is considering to change the Image struct and embedding the
Platform type (see opencontainers/image-spec#959) in the go implementation.
Moby currently uses some struct-literals to propagate the platform fields,
which will break once those changes in the OCI spec are merged.
Ideally (once that change arrives) we would update the code to set the Platform
information as a whole, instead of assigning related fields individually, but
in some cases in the code, image platform information is only partially set
(for example, OSVersion and OSFeatures are not preserved in all cases). This
may be on purpose, so needs to be reviewed.
This patch keeps the current behavior (assigning only specific fields), but
removes the use of struct-literals to make the code compatible with the
upcoming changes in the image-spec module.
