Base Image Remediation

This screenshot shows alternative images that may be used in the Dockerfile's FROM line to reduce vulnerabilities. Minor upgrades are the most likely to be compatible, Major are potentially breaking depending on how the image is used, and Alternative architecture images are given for more technical users to investigate.

Base Image Vulnerability

This screenshot shows an image with a vulnerability introduced by the base image (the FROM line in a Dockerfile) with the "Introduced by your base image ..." line

Binary Vulnerability

This screenshot shows a binary vulnerability; something not managed by the package manager of the operating system inside the container.

User-introduced / Dockerfile Vulnerability

This screenshot shows an image introduced by a user in their Dockerfile and highlights the exact command that introduced the vulnerability, with the "Introduced in your Dockerfile by ..." line
