CVE-2016-2422: Android Wi‑Fi can grant apps extra privileges

CVE-2016-2422 · published 10 years ago

Summary

Certain Android versions allow a Wi‑Fi certificate to be used for other purposes, letting a malicious app gain higher system access. This could let attackers control the device or access sensitive data. Update Android to the latest version or apply available security patches to stop this behavior.
