CVE-2011-3147: qcow format could expose host filesystem information

Versions of nova before 2012.1 could expose hypervisor host files to a guest operating system when processing a maliciously constructed qcow filesystem.

Security readout for executives and security teams

A malicious qcow filesystem image could let a guest operating system see limited information from the hypervisor host filesystem in Nova versions before 2012.1. The recorded impact is confidentiality-only and low severity, but it matters if very old Nova infrastructure still processes untrusted guest images. Exposure is most likely in legacy Nova deployments older than 2012.1 that still allow tenants or users to supply qcow-based guest filesystems. The source bundle does not provide complete vendor, product, CPE, or platform mapping. Treat this as a low-priority legacy infrastructure issue unless the organization still runs pre-2012.1 Nova with untrusted image processing. Confirm exposure during virtualization platform inventory rather than escalating as an active incident. Mitigation focus: Inventory Nova deployments and confirm whether any are older than 2012.1.; Upgrade legacy Nova instances to 2012.1 or later where supported.; Check OpenStack or distribution vendor advisories for exact fixed packages..
