NVD Description

Note: Versions mentioned in the description apply only to the upstream software-properties package and not the software-properties package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

dbus/SoftwarePropertiesDBus.py in Software Properties 0.92.17 before 0.92.17.3, 0.92.9 before 0.92.9.3, and 0.82.7 before 0.82.7.5 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, a related issue to CVE-2013-4288.
