DESCRIPTION:
Some vulnerabilities have been reported in Moodle, which can be
exploited by malicious people to disclose potentially sensitive
information, conduct HTTP header injection and spoofing attacks, and
bypass certain security restrictions.

1) An error related to the history and deletion user interfaces (UIs)
within the wiki can lead to disclosure of the username of a creator.

2) An error related to the messaging interface using
user/action_redir can lead to disclosure of the email address of a
user.

This is related to vulnerability #1 in:
SA47076

3) The weakness is caused due to improper handling of HTTP request
headers related to calendar/set.php and can be exploited to inject
arbitrary headers.

This is related to vulnerability #2 in:
SA47076

4) Due to an error within the web services login restrictions are not
properly enforced when authenticating users.

These vulnerabilities are reported in versions 2.1 through 2.1.2+ and
versions 2.0 through 2.0.5+.

5) Certain unspecified input passed via the "$returnurl" variable
within the Calendar set page is not properly verified before being
used to redirect users. This can be exploited to redirect a user to
an arbitrary website.

This vulnerability is reported in versions 2.1 through 2.1.2+.

SOLUTION:
Update to version 2.1.3 or later or version 2.0.6 or later.
