Debian: DSA-1761-1 Critical: Moodle TeX Filter Input Issue

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.
