Updated moodle packages fix security vulnerability
In Moodle before 2.8.11, teachers who otherwise were not supposed to see students' emails could see them in the participants list (CVE-2016-2151).
In Moodle before 2.8.11, Moodle traditionally trusted content from external DB, however it was decided that external datasources may not be aware of web security practices and data could cause problems after importing to Moodle (CVE-2016-2152).
In Moodle before 2.8.11, a user with higher permissions could be tricked into clicking a link which would result in Reflected XSS in mod_data advanced search (CVE-2016-2153).
In Moodle before 2.8.11, users without capability to view hidden courses but with capability to subscribe to Event Monitor rules could see the names of hidden courses (CVE-2016-2154).

In Moodle before 2.8.11, users without the capability to view hidden acitivites could still see associated calendar events via web services, via the external function get_calendar_events (CVE-2016-2156).
In Moodle before 2.8.11, CSRF is possible on the Assignment plugin admin page, however an exploit is unlikely to benefit anybody and can easily be reversed (CVE-2016-2157).
In Moodle before 2.8.11, enumeration of course category details is possible without authentication (CVE-2016-2158).
In Moodle before 2.8.11, students were able to add assignment submissions after the due date through web service, via the external function mod_assign_save_submission (CVE-2016-2159).
