Description Michael Kaplan 2020-10-21 16:42:33 UTC
kpmcore_externalcommand helper contains a logic flaw in which the service invoking dbus
is not properly checked. An attacker on your local machine can replace /etc/fstab,
execute mount and other partitioning related commands while KDE Partition Manager is running.
mount command can then be used to gain full root privileges.
