Vulnerability Summary

Vulnerabilities Fixed ✅

1. istioctl (FIXED)

Location: usr/local/bin/istioctl

Vulnerabilities:

Fix Applied: Updated from version 1.28.0 to 1.28.1 (released Dec 3, 2025)

  • Line 175: ENV ISTIO_VERSION=1.28.1
  • This version should include updated dependencies and be compiled with newer Go stdlib

Why it can be fixed: Istio releases are frequent and the latest stable version (1.28.1) contains the necessary security patches.


2. rootlesskit (FIXED)

Location: usr/bin/rootlesskit and usr/bin/rootlesskit-docker-proxy

Vulnerabilities:

  • stdlib v1.24.3 → needs v1.24.4 or v1.24.6

Fix Applied: Pinned to explicit version v2.3.5 (latest stable, released May 2025)

  • Line 225: Changed from dynamic lookup to ROOTLESSKIT_VERSION=v2.3.5

Why it can be fixed: The latest stable release v2.3.5 should be compiled with a newer Go version that addresses the stdlib vulnerabilities. By pinning the version, we ensure reproducible builds and can track when newer versions are available.
