Description

The check_permission_v1 function in base/pkit.py in HP Linux Imaging and Printing (HPLIP) through 3.13.9 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process.
