DESCRIPTION:
Multiple vulnerabilities have been reported in Moodle, which can be
exploited by malicious users and malicious people to bypass certain
security restrictions.

1) Input passed to unspecified parameters is not properly sanitised
before being used to construct an email message. This can be
exploited to inject arbitrary email headers.

This vulnerability is reported in versions 2.2, 2.1 through 2.1.3+,
and 2.0 through 2.0.6+.

2) An error in the application does not invalidate a deleted user's
session and can be exploited to bypass the authentication mechanism
by providing a token.

This vulnerability is reported in versions 2.2, 2.1 through 2.1.3+,
and 2.0 through 2.0.6+.

3) An error in the course self-enrolment feature can be exploited to
enroll as manager.

Successful exploitation of this vulnerability requires a teacher
account.

This vulnerability is reported in versions 2.2 and 2.1 through
2.1.3+.

SOLUTION:
Update to version 2.2.1 or later, 2.1.4 or later, or 2.0.7 or later.
