HIGH 7.8

DescriptionCVE.org

A script injection vulnerability was identified in the Tuned package. The instance_create() D-Bus function can be called by locally logged-in users without authentication. This flaw allows a local non-privileged user to execute a D-Bus call with script_pre or script_post options that permit arbitrary scripts with their absolute paths to be passed. These user or attacker-controlled executable scripts or programs could then be executed by Tuned with root privileges that could allow attackers to local privilege escalation.
