CVE-ID : CVE-2020-27187
Package : kpmcore
Type : privilege escalation
Remote : No
Link : https://security.archlinux.org/AVG-1253
The package kpmcore before version 4.2.0-1 is vulnerable to privilege
escalation.
Upgrade to 4.2.0-1.
The problem has been fixed upstream in version 4.2.0.
None.
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.
A local attacker is able to escalate privileges, modify the filesystem
and launch partition commands on the host while the program is running.
