moodle vulnerability
CVE-2009-1171
A security issue affects the following Ubuntu releases:
Ubuntu 9.04
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
The problem can be corrected by upgrading your system to the
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)
