-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Sun Java Web Start. User interaction is

class. A directory traversal flaw in this method allows the creation of
arbitrary files on the target system. After the file has been created, a
call to Runtime.getRuntime.exec() can be used to execute the file.
