Description: Allow only word characters in filename suffixes
 CVE-2013-4407: Allow only word characters in filename suffixes. An
 attacker able to upload files to a service that uses
 HTTP::Body::Multipart could use this issue to upload a file and create
 a specifically-crafted temporary filename on the server, that when
 processed without further validation, could allow execution of commands
 on the server.
