A security bypass vulnerability affects the third-party library utilized by Moodle, phpCAS. Specifically, this is a flaw related to improper URL encoding in the back-channel ticket validation. With a specially crafted request, a remote attacker can bypass intended security constraints. (MSA-14-0033 / CVE-2014-4172)
An information disclosure vulnerability affects the Q&A forum. Specifically, this affects the script ‘/mod/forum/view.php’ by allowing users who had not yet posted the required answer to see the name of the last person who had posted their answer. (MSA-14-0034 / CVE-2014-3617)
