DSA-1761-1 moodle -- missing input sanitization

Related Vulnerabilities: CVE-2009-1171  

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.
