More information:

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

  • CVE-2009-0500

    It was discovered that the information stored in the log tables was not properly sanitized, which could allow attackers to inject arbitrary web code.

  • CVE-2009-0502

    It was discovered that certain input via the "Login as" function was not properly sanitised leading to the injection of arbitrary web script.

  • CVE-2008-5153

    Dmitry E. Oboukhov discovered that the SpellCheker plugin creates temporary files insecurely, allowing a denial of service attack. Since the plugin was unused, it is removed in this update.

For the stable distribution (etch) these problems have been fixed in version 1.6.3-2+etch2.

For the testing (lenny) distribution these problems have been fixed in version 1.8.2.dfsg-3+lenny1.
