Debian Security Advisory DSA 1724-1 security@debian.org
http://www.debian.org/security/ Steffen Joeris
February 13th, 2009 http://www.debian.org/security/faq
- --------------------------------------------------------------------------

Package : moodle
Vulnerability : several vulnerabilities
Problem type : remote
Debian-specific: no
CVE IDs : CVE-2009-0500 CVE-2009-0502 CVE-2008-5153
Debian Bug : 514284

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


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


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


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.

For the unstable (sid) distribution these problems have been fixed in
version 1.8.2.dfsg-4.

We recommend that you upgrade your moodle package.
