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).
