(RHSA-2013:1194) Important: jbossweb security update

JBoss Web is the web container, based on Apache Tomcat, in Red Hat
JBoss Enterprise Application Platform. It provides a single deployment
platform for the JavaServer Pages (JSP) and Java Servlet technologies.

A flaw was found in the way the DiskFileItem class handled NULL characters
in file names. A remote attacker able to supply a serialized instance of
the DiskFileItem class, which will be deserialized on a server, could use
this flaw to write arbitrary content to any location on the server that is
accessible to the user running the application server process.
