## Description

java/org/apache/catalina/servlets/DefaultServlet.java in the default
servlet in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before
8.0.4 does not properly restrict XSLT stylesheets, which allows remote
attackers to bypass security-manager restrictions and read arbitrary files
via a crafted web application that provides an XML external entity
declaration in conjunction with an entity reference, related to an XML
External Entity (XXE) issue.

### From the Ubuntu Security Team

It was discovered that Tomcat did not properly restrict XSLT stylesheets.
An attacker could use this issue with a crafted web application to bypass
security-manager restrictions and read arbitrary files.
