Description

The instance rescue mode in OpenStack Compute (Nova) 2013.2 before 2013.2.3 and Icehouse before 2014.1, when using libvirt to spawn images and use_cow_images is set to false, allows remote authenticated users to read certain compute host files by overwriting an instance disk with a crafted image.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nova. 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 nova to 12.0.0a0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2014-0134 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 CVE-2014-0134 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 CVE-2014-0134. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
