Updated moodle package fixes security vulnerabilities:

In Moodle before 2.6.9, by modifying URL a logged in user can view the list of another user's contacts, number of unread messages and list of their courses (CVE-2015-2266).

In Moodle before 2.6.9, authentication in mdeploy can be bypassed. It is theoretically possible to extract files anywhere on the system where the web server has write access. The attacking user must know details about the system and already have significant permissions on the site (CVE-2015-2267).

In Moodle before 2.6.9, a non-optimal regular expression in the "Convert links to URLs" filter could be exploited to create extra server load or make particular pages unavailable (CVE-2015-2268).

In Moodle before 2.6.9, it is possible to create HTML injection through blocks with configurable titles, however this could only be exploited by users who are already marked as XSS-trusted (CVE-2015-2269).

In Moodle before 2.6.9, for the custom themes that use blocks regions in the base layout the blocks for inaccessible courses could be displayed together with sensitive course-related information. Most of the themes, including all standard Moodle themes, are not affected (CVE-2015-2270).

In Moodle before 2.6.9, users without proper permission are able to mark tags as inappropriate. Since this capability is given to authenticated users by default, this is not an issue for most sites (CVE-2015-2271).

In Moodle before 2.6.9, even when user's password is forced to be changed on login, user could still use it for authentication in order to create the web service token and therefore extend the life of the temporary password via web services (CVE-2015-2272).

In Moodle before 2.6.9, Quiz statistics report did not properly escape student responses and could be used for XSS attack (CVE-2015-2273).

mdeploy.php in Moodle through 2.5.9, 2.6.x before 2.6.9, 2.7.x before 2.7.6, and 2.8.x before 2.8.4 allows remote authenticated users to bypass intended access restrictions and extract archives to arbitrary directories via a crafted dataroot value.
