Arch Linux Security Advisory ASA-201802-4

Severity: High
Date    : 2018-02-09
CVE-ID  : CVE-2018-6791
Package : plasma-workspace
Type    : arbitrary command execution
Remote  : No
Link    :


The package plasma-workspace before version 5.12.0-1 is vulnerable to
arbitrary command execution.


Upgrade to 5.12.0-1.

# pacman -Syu "plasma-workspace>=5.12.0-1"

The problem has been fixed upstream in version 5.12.0.


Mount removable devices with Dolphin instead of the device notifier.


When a vfat thumbdrive which contains `` or $() in its volume label is
plugged and mounted trough the device notifier, it's interpreted as a
shell command, leaving a possibility of arbitrary commands execution.
an example of offending volume label is "$(touch b)" which will create
a file called b in the home folder.


A local attacker is able to execute arbitrary commands on the affected
system by inserting and mounting a specially crafted thumbdrive.
