Package        : moodle
Vulnerability  : missing input sanitization
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2009-1171
Debian Bug     : 522116


Christian J. Eibl discovered that the TeX filter of Moodle, a web-based
course management system, doesn't check user input for certain TeX commands
which allows an attacker to include and display the content of arbitrary system
files.

Note that this doesn't affect installations that only use the mimetex
environment.

For the oldstable distribution (etch), this problem has been fixed in
version 1.6.3-2+etch3.

For the stable distribution (lenny), this problem has been fixed in
version 1.8.2.dfsg-3+lenny2.

For the testing distribution (squeeze), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 1.8.2.dfsg-5.


We recommend that you upgrade your moodle packages.

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.
