moodle - several vulnerabilities

Several vulnerabilities have been discovered in Moodle, an online
course management system. The Common Vulnerabilities and Exposures
project identifies the following problems:

• CVE-2009-4297
  Multiple cross-site request forgery (CSRF) vulnerabilities have been
  discovered.
• CVE-2009-4298
  It has been discovered that the LAMS module is prone to the disclosure
  of user account information.
• CVE-2009-4299
  The Glossary module has an insufficient access control mechanism.
• CVE-2009-4301
  Moodle does not properly check permissions when the MNET service is
  enabled, which allows remote authenticated servers to execute arbitrary
  MNET functions.
• CVE-2009-4302
  The login/index_form.html page links to an HTTP page instead of using an
  SSL secured connection.
• CVE-2009-4303
  Moodle stores sensitive data in backup files, which might make it
  possible for attackers to obtain them.
• CVE-2009-4305
  It has been discovered that the SCORM module is prone to an SQL
  injection.

Additionally, an SQL injection in the update_record function, a problem
with symbolic links and a verification problem with Glossary, database
and forum ratings have been fixed.

For the stable distribution (lenny), these problems have been fixed in
version 1.8.2.dfsg-3+lenny3.

For the oldstable distribution (etch), there are no fixed packages
available and it is too hard to backport many of the fixes. Therefore,
we recommend to upgrade to the lenny version.

For the testing distribution (squeeze) and the unstable distribution
(sid), these problems have been fixed in version 1.8.2.dfsg-6.

We recommend that you upgrade your moodle packages.
