## Description

In Apache FOP before 2.2, files lying on the filesystem of the server which
uses FOP can be revealed to arbitrary users who send maliciously formed SVG
files. The file types that can be shown depend on the user context in which
the exploitable application is running. If the user is root a full
compromise of the server - including confidential or sensitive files -
would be possible. XXE can also be used to attack the availability of the
server via denial of service as the references within a xml document can
trivially trigger an amplification attack.
