DESCRIPTION:
Two security issues have been reported in Moodle, which can be
exploited by malicious users to bypass certain security
restrictions.

1) An error in the "role_assign()" function of the role assignment
web service does not validate access permissions and can be exploited
to assign roles.

2) An error in the handling of access permissions of a course creator
can be exploited to change the local filter settings for a course.

The security issues are reported in versions prior to 2.0.4 and
2.1.1.

SOLUTION:
Update to version 2.0.4 or 2.1.1 and manually alter the permissions
to remove rights from course creators.
