1 month ago I think maybe this issue has the wrong Dockerfile snippet?
FROM registry.suse.com/suse/sle15:15.5
RUN zypper in -y --no-recommends python3-rsa=3.4.2-150000.3.7.1
ENTRYPOINT [""]
CMD ["bash"]installs python-rsa, but this is about a Ruby issue. Maybe a copy and paste error from the python-rsa false positive.
Anyway, @sekveaja when you have a chance could you add a corrected Dockerfile?
What happened:
Scan on image that has ruby2.5-stdlib-2.5.9-150000.4.29.1.x86_64 installed. It generates high vulnerability:
{ "vulnerability": { "id": "GHSA-gwfg-cqmg-cf8f", "dataSource": "https://github.com/advisories/GHSA-gwfg-cqmg-cf8f", "namespace": "github:language:ruby", "severity": "High", "urls": [ "https://github.com/advisories/GHSA-gwfg-cqmg-cf8f" ], "description": "WEBRick vulnerable to HTTP Request/Response Smuggling", "cvss": [

What you expected to happen:
Look into SUSE Advisory CVE-2020-25613
SUSE Linux Enterprise Server 15 SP5
libruby2_5-2_5 >= 2.5.8-4.14.1 ruby2.5 >= 2.5.8-4.14.1 ruby2.5-devel >= 2.5.8-4.14.1 ruby2.5-devel-extra >= 2.5.8-4.14.1 ruby2.5-stdlib >= 2.5.8-4.14.1 Patchnames: SUSE Linux Enterprise Module for Basesystem 15 SP5 GA libruby2_5-2_5-2.5.9-150000.4.26.1 SUSE Linux Enterprise Module for Basesystem 15 SP5 GA ruby2.5-2.5.9-150000.4.26.1
Installed version in the container is
rpm -qa | grep ruby2
libruby2_5-2_5-2.5.9-150000.4.29.1.x86_64 ruby2.5-stdlib-2.5.9-150000.4.29.1.x86_64 ruby2.5-rubygem-gem2rpm-0.10.1-3.45.x86_64 ruby2.5-2.5.9-150000.4.29.1.x86_64 ruby2.5-rubygem-bundler-1.16.1-3.3.1.x86_64
Conclusion: Installed version exceed minimum requirement patch from SLES 15.5 but Grype generate a vulnerability. Therefore, it is a false positive when looking at SUSE eco-system.
How to reproduce it (as minimally and precisely as possible):
1)Create the Dockerfile with this content:
FROM registry.suse.com/suse/sle15:15.5 RUN zypper in -y --no-recommends python3-rsa=3.4.2-150000.3.7.1 ENTRYPOINT [""] CMD ["bash"]
2) Build an image from Dockerfile
docker build -t "suse15.5_test:v1" .
3) Test with Grype now $ grype suse15.5_test:v1
NAME INSTALLED FIXED-IN TYPE VULNERABILITY SEVERITY webrick 1.4.2.1 1.6.1 gem GHSA-gwfg-cqmg-cf8f High
$ grype --distro sles:15.5 suse15.5_test:v1 NAME INSTALLED FIXED-IN TYPE VULNERABILITY SEVERITY webrick 1.4.2.1 1.6.1 gem GHSA-gwfg-cqmg-cf8f High
Anything else we need to know?:
Environment:
$ grype --version grype 0.76.0
In container image eco-system:
