$ go version go version go1.16.2 linux/amd64
Does this issue reproduce with the latest release?
Yes, using the latest version of the Go 1.16 alpine Docker image (hash 52dbfc81ec12df22e2ab1e7c9c4f4ee3dff73514e56a54924714d29ac03ff791)

What did you do?
We have vulnerability scanning on all Docker images as a part of our deployment pipeline, and even an image with no Go projects in it was flagged as being affected by the crypto/ssh vulnerability fixed in this commit. Here is the Snyk vulnerability page.
This is the flagged Docker image:
Dockerfile
FROM golang:1.16-alpine@sha256:3411aef9ae9cb0fe3534fe2a4d1a9745d952d9a5ed1e20a11ff10549731156e8 # Installing dependencies RUN apk upgrade --no-cache && \ apk add --no-cache \ bash \ # Install Git git \ nodejs \ npm \ make \ gcc musl-dev python3-dev libffi-dev openssl-dev \ python3 \ py3-pip && \ echo "*** setup python ***" && \ ln -sf python3 /usr/bin/python && \ pip install wheel && \ rm -rf /root/.cache/pip
As an aside, is there a way to force a Docker image to install a newer version of a built-in module? I tried doing a go get -u golang.org/x/crypto/ssh, however it did not fix the problem 😞
Any help would be greatly appreciated! Just checking to make sure it's not because of something silly I've done 😄
