CVE-2018-16267
The system-popup system service in Tizen allows an unprivileged process to perform popup-related system actions, due to improper D-Bus security policy configurations.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.68%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The system-popup system service in Tizen allows an unprivileged process to perform popup-related system actions, due to improper D-Bus security policy configurations. Such actions include the triggering system poweroff menu, and prompting a popup with arbitrary strings. This affects Tizen before 5.0 M1, and Tizen-based firmwares including Samsung Galaxy Gear series before build RE2.
