What is CVE-2015-1327?
CVE-2015-1327 is a low-severity missing authorization vulnerability in Canonical Ubuntu Linux, published on 22 Apr 2019. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
Content Hub before version 0.0+15.04.20150331-0ubuntu1.0 DBUS API only requires a file path for a content item, it doesn't actually require the confined app have access to the file to create a transfer. This could allow a malicious application using the DBUS API to export file:///etc/passwd which would then send a copy of that file to another app.
