The pkgmgr system service in Tizen allows an unprivileged process to perform package management actions, due to improper D-Bus security policy configurations. Such actions include installing, decrypting, and killing other packages. This affects Tizen before 5.0 M1, and Tizen-based firmwares including Samsung Galaxy Gear series before build RE2.

Weakness

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
