RELIABLE

This image carries significant risk; production deployment is highly discouraged without strict compensating controls. An attacker could cause a denial of service by sending a crafted regex input, exploiting CVE-2017-11164 in the PCRE library, causing the Envoy proxy to crash or hang. This vulnerability affects default configurations as regex matching is a core feature of Envoy for routing and filters. Post-exploit vulnerabilities are minimal (max severity 3.0) and not remotely exploitable, limiting the impact of a successful breach. Despite the high reputation of the publisher and use of pinned digest, the presence of a remotely triggerable DoS warrants caution.

Scanning procedure

  1. Vulnerability scan
    Full CVE sweep across OS packages and app dependencies
  2. Exploitability check
    CVEs ranked by exploit probability (EPSS) and matched against CISA KEV
  3. Reachability analysis
    Symbol-level proof: is the vulnerable code even linked and callable in your binaries?
  4. Runtime verification
    Live-container probes: exposed endpoints, feature flags, real defaults
  5. Supply chain analysis
    Base-image lineage, package provenance and signatures — nothing slipped in unnoticed
  6. Hardening recommendations
    A hardened build plan — patch, remove unused packages, lock down the runtime — with parity tests proving nothing broke
