Add image scan script

[ivanvc]

Introduce a new script that can run on stable branches that checks the vulnerabilities for the latest tag (from the given branch).

Adds Trivy as a tool dependency, to keep track of the latest released version.

A periodic Prow job will later execute this. We'll get alerts when a CVE is found in our images, either by a direct vulnerability or for a dependency with a reported vulnerability of high or critical severity.

Part of #19363.

Oof, inconsistent dependencies. I'll draft and will undraft once I address those 😅.

Adding Trivy as a tool bumped many indirect dependencies, resulting in changes to many go.mods.

My understanding is that you only introduce a new dependency on github.com/aquasecurity/trivy, could you move unrelated dependencies bumping into a separate PR to make this PR easier to review?

I opened #19819.

But I wonder if it makes more sense to open a pull request to only bump the existing dependencies without introducing Trivy. Let me know, and I can do that instead.

Edit: I opened #19821, which does the latter.

[ahrtr]

@ivanvc Probably I did not say it clearly in my previous comment.

Adding dependency github.com/aquasecurity/trivy is OK, because it's required for the image scan script. It's OK to do both things (see below) in one PR,

• Add dependency github.com/aquasecurity/trivy
• Add image scan script

But I see that you bumped many other dependencies as well in this PR. Can you move all other dependencies bumping into a separate PR?

[ivanvc]

@ahrtr, then, please take a look at #19821.

I'll close #19819, then.

[ahrtr]

Please rebase this PR.

[ivanvc]

I'll get back to this shortly. I'm a bit busy and reconsidering how we'll implement this in the stable release branches. Either way, the trivy dependency is required, so it's good that we bumped the indirect dependencies.
