Debian DSA-1761-1 : moodle - missing input sanitization

medium Nessus Plugin ID 36084

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the moodle packages.

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.
