Description

Summary

Vulnerability scan of fiona shows CVE-2020-14152. The vulnerability is in libjpeg, a transitive dependency of fiona (via GDAL and PROJ).

Details

In IJG JPEG (aka libjpeg) before 9d, jpeg_mem_available() in jmemnobs.c in djpeg does not honor the max_memory_to_use setting, possibly causing excessive memory consumption.

Impact

fiona will not open JPEG files and is not vulnerable to attack in that way. fiona might be vulnerable to malformed PROJ grid files using JPEG compression. No such vulnerability or compromise has been demonstrated.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for fiona. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update fiona to 1.10b2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g4m4-9q4c-mfw6 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-g4m4-9q4c-mfw6 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-g4m4-9q4c-mfw6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
