CVE-2018-6791 (opens in a new tab)How to fix?
Upgrade Ubuntu:17.10 plasma-workspace to version 4:5.10.5-0ubuntu1.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream plasma-workspace package and not the plasma-workspace package as distributed by Ubuntu.
See How to fix? for Ubuntu:17.10 relevant fixed versions and status.
An issue was discovered in soliduiserver/deviceserviceaction.cpp in KDE Plasma Workspace before 5.12.0. When a vfat thumbdrive that contains `` or $() in its volume label is plugged in and mounted through the device notifier, it's interpreted as a shell command, leading to a possibility of arbitrary command execution. An example of an offending volume label is "$(touch b)" -- this will create a file called b in the home folder.
