Description

CVE-2009-1171: The TeX filter in Moodle 1.6 before 1.6.9+, 1.7 before 1.7.7+, 1.8 before 1.8.9, and 1.9 before 1.9.5 allows user-assisted attackers to read arbitrary files via an input command in a '$$' sequence, which causes LaTeX to include the contents of the file. Upstream bug and CVS commit: http://tracker.moodle.org/browse/MDL-18552 http://cvs.moodle.org/moodle/filter/tex/filter.php?r1=1.18.4.4&r2=1.18 .4.5
