Hello,
We're using official Apache Flink Java images as base images in our project, but our security scans have identified numerous vulnerabilities originating from these base images. We want to continue using official images; however, to do so, we must address these security issues. It appears that the majority of vulnerabilities stem from Ubuntu 22, which is part of the jre-jammy base image. We propose switching to the jre-noble base image to migrate to Ubuntu 24, which contains the latest security fixes.
