CVE-2009-1171
===========================================================

A security issue affects the following Ubuntu releases:

This advisory also applies to the corresponding versions of

following package versions:

Ubuntu 9.04:
  moodle                          1.9.4.dfsg-0ubuntu1.1

After a standard system upgrade you need to access the Moodle instance
and accept the database update to clear any invalid cached data.

Details follow:

Christian Eibl discovered that the TeX filter in Moodle allowed any
function to be used.  An authenticated remote attacker could post
a specially crafted TeX formula to execute arbitrary TeX functions,
potentially reading any file accessible to the web server user, leading
to a loss of privacy.  (CVE-2009-1171, MSA-09-0009)
