Arch Linux Security Advisory ASA-201802-4
Date : 2018-02-09
CVE-ID : CVE-2018-6791
Package : plasma-workspace
Type : arbitrary command execution
Remote : No
Link : https://security.archlinux.org/AVG-607
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.
