Description

The vulnerability allows a remote attacker to gain elevated privileges on the target system.

The weakness exists due to the authorization mechanism that is intended to limit requests, PolicyKit, is configured to automatically grant access to requests originating from the root user. A remote attacker can use legitimate requests that reach /bin/ssid’s .srv functionality, choose one of several actions by setting the action parameter in the request’s query-string and invoke any dbus request as root (the uid and gid of the /bin/ssid process), without any restriction on the destination or content.

Mitigation
Install update from vendor's website.
