## Description

signond before 8.57+15.04.20141127.1-0ubuntu1, as used in Ubuntu Touch, did
not properly restrict applications from querying oath tokens due to
incorrect checks and the missing installation of the
signon-apparmor-extension. An attacker could use this create a malicious
click app that collects oauth tokens for other applications, exposing
sensitive information.
