Security readout for executives and security teams
Plain-English summary
This flaw could let an Ubuntu application keep receiving location data after a user revoked that permission. Business impact is privacy exposure rather than system takeover. The issue is fixed in named Canonical trust-store package versions, and no provided source indicates active exploitation.
Executive priority
Treat as a moderate privacy-risk issue. It is most urgent for products or managed devices where location privacy is regulated, contractual, or customer-facing. Patch validation should be scheduled, but the sources do not support emergency exploitation claims.
Technical view
Ubuntu trust-store cached authorization results incorrectly because Select in src/core/trust/impl/sqlite3/store.cpp did not order cache entries by creation time. A stale location permission decision could be honored after revocation, allowing continued location access. CVSS is 5.0 with local access, low complexity, low privileges, user interaction, and high confidentiality impact.
Likely exposure
Exposure appears limited to systems using affected Canonical trust-store 1.1.0 or Ubuntu RTM trust-store 1.1.0 for application location authorization.
Exploitation context
The provided data does not show KEV listing or active exploitation. Abuse would require a local application context and a permission state where location access was revoked but stale cached authorization remained effective.
Researcher notes
Focus validation on stale authorization decisions after revocation, not code execution. The root cause is cache selection ordering in the sqlite3 trust-store implementation. Evidence is specific to location permission handling and the two Canonical package tracks named in the CVE data.
Mitigation direction
- Upgrade Ubuntu trust-store to 1.1.0+15.04.20150123-0ubuntu1 or later.
- Upgrade Ubuntu RTM trust-store to 1.1.0+15.04.20150123~rtm-0ubuntu1 or later.
- Check Canonical guidance for applicable backported packages or supported release handling.
- Prioritize devices or images that expose location services to third-party applications.
Validation and detection
- Inventory installed trust-store package versions on relevant Ubuntu or Ubuntu RTM systems.
- Confirm the installed package is at or above the fixed version named by Canonical.
- Review application permission revocation behavior for location-sensitive deployments.
- Check whether affected devices still run obsolete Ubuntu trust-store builds.
