The Apache Commons FileUpload component can be used to add a file upload
capability to your applications.

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.

All users of the affected products as provided from the Red Hat Customer
Portal are advised to apply this update.

existing Red Hat JBoss BRMS installation (including all applications and

starting the JBoss Application Server process.
