An issue was discovered in the cantata-mounter D-Bus service in Cantata
through 2.3.1. The mount target path check in mounter.cpp mpOk() is
insufficient. A regular user can consequently mount a CIFS filesystem
anywhere (e.g., outside of the /home directory tree) by passing directory
traversal sequences such as a home/…/usr substring.
