DSA-2115-1 introduced a regression because it lacked a dependency on
the wwwconfig-common package, leading to installations problems.  This
update addresses this issue.  For reference, the text of the original
advisory is provided below.

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

	Moodle does not enable the "Regenerate session id during
	login" setting by default, which makes it easier for remote
	attackers to conduct session fixation attacks.

	Multiple cross-site scripting (XSS) vulnerabilities allow
	remote attackers to inject arbitrary web script or HTML via
	vectors related to (1) the Login-As feature or (2) when the
	global search feature is enabled, unspecified global search
	forms in the Global Search Engine.

	Multiple SQL injection vulnerabilities allow remote attackers
	to execute arbitrary SQL commands via vectors related to (1)
	the add_to_log function in mod/wiki/view.php in the wiki
	module, or (2) "data validation in some forms elements"
	related to lib/form/selectgroups.php.

	Moodle can create new roles when restoring a course, which
	allows teachers to create new accounts even if they do not
	have the moodle/user:create capability.

	user/view.php does not properly check a role, which allows
	remote authenticated users to obtain the full names of other
	users via the course profile page.

	A Cross-site scripting (XSS) vulnerability in the phpCAS
	client library allows remote attackers to inject arbitrary web
	script or HTML via a crafted URL, which is not properly
	handled in an error message.

	A Cross-site scripting (XSS) vulnerability in the
	fix_non_standard_entities function in the KSES HTML text
	cleaning library (weblib.php) allows remote attackers to
	inject arbitrary web script or HTML via crafted HTML entities.

	A Cross-site scripting (XSS) vulnerability in the MNET
	access-control interface allows remote attackers to inject
	arbitrary web script or HTML via vectors involving extended
	characters in a username.

	Multiple cross-site scripting (XSS) vulnerabilities in
	blog/index.php allow remote attackers to inject arbitrary web
	script or HTML via unspecified parameters.

	The KSES text cleaning filter in lib/weblib.php does
	not properly handle vbscript URIs, which allows remote
	authenticated users to conduct cross-site scripting (XSS)
	attacks via HTML input.

	A Cross-site request forgery (CSRF) vulnerability in
	report/overview/report.php in the quiz module allows remote
	attackers to hijack the authentication of arbitrary users for
	requests that delete quiz attempts via the attemptid

This security update switches to a new upstream version and requires
database updates.  After installing the fixed package, you must visit
<http://localhost/moodle/admin/> and follow the update instructions.

For the stable distribution (lenny), these problems have been fixed in
version 1.8.13-2.

For the unstable distribution (sid), these problems have been fixed in
version 1.9.9.dfsg2-1.

We recommend that you upgrade your moodle package.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
