Vulnerability Name:

CVE-2018-6791 (CCN-138840)

Assigned:2018-02-03
Published:2018-02-03
Updated:2019-10-03
Summary: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.
