Updated moodle package fixes security vulnerabilities:

In Moodle before 2.6.11, leaving gradebook feedback is a trusted action and such capabilities in other modules already have an XSS mask, 'mod/quiz:grade' was missing this flag (CVE-2015-3174).

In Moodle before 2.6.11, some error messages display a button to return to the previous page. Redirecting to non-local referer should not be allowed as it can potentially be used for phising (CVE-2015-3175).

In Moodle before 2.6.11, on sites with enabled self-registration, not registered users can retrieve fullname of registered users if they know their usernames (CVE-2015-3176).

In Moodle before 2.6.11, if a user who is not XSS-trusted attempts to insert a script as part of the input text, it will be cleaned when displayed on the Moodle website but may be displayed uncleaned in the external application because external_format_text() cleans and formats text incorrectly when returning it from Web Services (CVE-2015-3178).

In Moodle before 2.6.11, when self-registration is enabled and a user's account was suspended after creating the account but before actually confirming it, the user is still able to login when confirming their email, but only once (CVE-2015-3179).

In Moodle before 2.6.11, if a user is enrolled in the course but his enrollment is suspended, they can not access the course but still were able to see the course structure in the navigation block (CVE-2015-3180).

In Moodle before 2.6.11, users with the revoked capability 'moodle/user:manageownfiles' are still able to upload private files using a deprecated function in Web Services (CVE-2015-3181).

The account-confirmation feature in login/confirm.php in Moodle through 2.5.9, 2.6.x before 2.6.11, 2.7.x before 2.7.8, and 2.8.x before 2.8.6 allows remote attackers to obtain sensitive full-name information by attempting to self-register.
