Debian: New moodle packages fix several vulnerabilities

Several vulnerabilities have been discovered in Moodle, an online course management system. Multiple cross-site request forgery (CSRF) vulnerabilities have been discovered. It has been discovered that the LAMS module is prone to the disclosure of user account information. The Glossary module has an insufficient access control mechanism. Moodle does not properly check permissions when the MNET service is enabled, which allows remote authenticated servers to execute arbitrary MNET functions. The login/index_form.html page links to an HTTP page instead of using an SSL secured connection. Moodle stores sensitive data in backup files, which might make it possible for attackers to obtain them. 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. Updated packages are available from security.debian.org.

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.
