[20.10] Update go 1.18.7 to address CVE-2022-2879, CVE-2022-2880, CVE-2022-41715
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.

Do not patch Dockerfiles in CI
When building the Dockerfiles for development, those images are mainly used to
create a reproducible build-environment. The source code is bind-mounted into
the image at runtime; there is no need to create an image with the actual
source code, and copying the source code into the image would lead to a new
image being created for each code-change (possibly leading up to many "dangling"
images for previous code-changes).
However, when building (and using) the development images in CI, bind-mounting
is not an option, because the daemon is running remotely.
To make this work, the circle-ci script patched the Dockerfiles when CI is run;
adding a `COPY` to the respective Dockerfiles.
Patching Dockerfiles is not really a "best practice" and, even though the source
code does not and up in the image, the source would still be _sent_ to the daemon
for each build (unless BuildKit is used).
This patch updates the makefiles, circle-ci script, and Dockerfiles;
- When building the Dockerfiles locally, pipe the Dockerfile through stdin.
Doing so, prevents the build-context from being sent to the daemon. This speeds
up the build, and doesn't fill up the Docker "temp" directory with content that's
not used
- Now that no content is sent, add the COPY instructions to the Dockerfiles, and
remove the code in the circle-ci script to "live patch" the Dockerfiles.
Before this patch is applied (with cache):
```
$ time make -f docker.Makefile build_shell_validate_image
docker build -t docker-cli-shell-validate -f ./dockerfiles/Dockerfile.shellcheck .
Sending build context to Docker daemon 41MB
Step 1/2 : FROM debian:stretch-slim
...

```
After this patch is applied (with cache)::
```
$ time make -f docker.Makefile build_shell_validate_image
cat ./dockerfiles/Dockerfile.shellcheck | docker build -t docker-cli-shell-validate -
Sending build context to Docker daemon 2.048kB
