CVE scan lists high vulnerability against latest image k8s.gcr.io/nfd/node-feature-discovery:v0.11.1

[gseidlerhpe]

What happened:
CVE scan shows image uses lib/package with high vulnerability

What you expected to happen:
No critical or high vulnerability issues.

How to reproduce it (as minimally and precisely as possible):
docker scan k8s.gcr.io/nfd/node-feature-discovery:v0.11.1

Output shows:
✗ High severity vulnerability found in gcc-8/libstdc++6

Your base image is out of date

1. Pull the latest version of your base image by running 'docker pull debian:10.12-slim'
2. Rebuild your local image

Anything else we need to know?:

Environment:

• Kubernetes version (use kubectl version):
• Cloud provider or hardware configuration:
• OS (e.g: cat /etc/os-release):
• Kernel (e.g. uname -a):

This will require v0.11.2 since updating image hash at k8s.gcr.io/images doesn't allow hash updates

[marquiz]

I don't think this applicable to us. NFD binaries are statically linked golang binaries (no c compiler involved). The possible hooks run by nfd (worker) inside the image are deployed/managed by the sysadmin. Any thoughts?

[eero-t]

As that's not the minimal image, according to documentation it contains run-time support for Bash and Perl hooks: https://kubernetes-sigs.github.io/node-feature-discovery/v0.11/advanced/customization-guide.html#hooks

I.e. has several libs that may get out of date / require security updates.

(IMHO running random code for hooks is bad idea for several reasons, I'll expand on that in a separate ticket.)

@gseidlerhpe v0.11.2 (#870) should fix this issue. Close?

[gseidlerhpe]

@marquiz unfortunately the v0.11.2 image still has critical and high vulnerabilities (mostly Debian and Go).

The basic docker scan (Snyk 1.827.0) lists 1 critical and 1 high:
✗ High severity vulnerability found in gcc-8/libstdc++6
Description: Information Exposure
Info: https://snyk.io/vuln/SNYK-DEBIAN10-GCC8-347558
Introduced through: gcc-8/libstdc++6@8.3.0-6, apt@1.8.2.3, meta-common-packages@meta
From: gcc-8/libstdc++6@8.3.0-6

From: apt@1.8.2.3 > apt/libapt-pkg5.0@1.8.2.3 > gcc-8/libstdc++6@8.3.0-6
and 2 more...

✗ Critical severity vulnerability found in zlib/zlib1g
Description: Out-of-bounds Write
Info: https://snyk.io/vuln/SNYK-DEBIAN10-ZLIB-2976149
Introduced through: meta-common-packages@meta
From: meta-common-packages@meta > zlib/zlib1g@1:1.2.11.dfsg-1+deb10u1

However, I also ran a more sensitive scan with Jfrog and that found many more: 10 critical, 28 high.

I've attached the full output in json format from both scans.
snyk-cve-scan-node-feature-discovery-v0.11.2.json.txt
jfrog-cve-scan-node-feature-discovery-v0.11.2.json.txt

Updating the base debian image should fix most if not all of the critical and high issues.
