Vulnerability Name:

CVE-2018-12559

Assigned:2018-06-19
Published:2018-06-19
Updated:2018-08-10
Summary: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.
