Several vulnerabilities have been discovered in libphp-adodb, the
'adodb' database abstraction layer for PHP, which is embedded in
moodle, a course management system for online learning.  The Common
Vulnerabilities and Exposures project identifies the following
problems:

CVE-2006-0146

     Andreas Sandblad discovered that improper user input sanitisation
     results in a potential remote SQL injection vulnerability enabling
     an attacker to compromise applications, access or modify data, or
     exploit vulnerabilities in the underlying database implementation.
     This requires the MySQL root password to be empty.  It is fixed by
     limiting access to the script in question.

CVE-2006-0147

     A dynamic code evaluation vulnerability allows remote attackers to
     execute arbitrary PHP functions via the 'do' parameter.

CVE-2006-0410

     Andy Staudacher discovered an SQL injection vulnerability due to
     insufficient input sanitising that allows remote attackers to
     execute arbitrary SQL commands.

CVE-2006-0806

     GulfTech Security Research discovered multiple cross-site
     scripting vulnerabilities due to improper user-supplied input
     sanitisation.  Attackers can exploit these vulnerabilities to
     cause arbitrary scripts to be executed in the browser of an
     unsuspecting user's machine, or result in the theft of
     cookie-based authentication credentials.

The old stable distribution (woody) does not contain moodle packages.

For the stable distribution (sarge) these problems have been fixed in
version 1.4.4.dfsg.1-3sarge1.

For the unstable distribution these problems will be fixed soon.

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.

   These files will probably be moved into the stable distribution on
   its next update.
