Hi @wespanther. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

To test, I build the image for all architectures and scanned it with both Container Analysis and Trivy. Neither turned up any vulnerabilities with fixes available.

@kubernetes/release-engineering do you have thoughts on automating this somehow?

[justaugustus]

/hold @wespanther Is this vuln present in the debian-base images? If so, we've got to bump and promote those first.

[wespanther]

@justaugustus it's not in the debian-base, only openssl in this image.

Edit: also updated another reference in dependencies.yaml, hadn't seen that one before.
