CVE-2018-6791 Information

Description

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.
