CVE-2018-16268

Unauthorized media actions via permissive D-Bus policy

Published Jan 22, 2020 · Updated Aug 5, 2024

Improper authorization in Tizen SoundServer/FocusServer before 5.0 M1 allows local users to trigger media actions through D-Bus. The system-bus policy grants unprivileged processes access to service methods that play attacker-selected sound files or DTMF tones. Local code execution on an affected device is required; the reported consequence is unauthorized audio playback, including on Galaxy Gear firmware before build RE2.
