DESCRIPTION:
A vulnerability has been reported in acpid, which can be exploited by
malicious, local users to gain escalated privileges.

The vulnerability is caused due to an error in the "powerbtn.sh"
script when identifying a process ID of the KDE session daemon. This
can be exploited to inject commands via the DBUS_SESSION_BUS_ADDRESS
environment variable.

The vulnerability is reported in version 2.0.12. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted users only or disable power button event
handling.
