Who is Vulnerable?
Vulnerability Description	Java Technology is a programing platform developed by Sun Microsystems which aims to provide a system for developing and deploying cross-platform applications. Java is used in a wide variety of programs that are deployed on personal computers as well as embedded devices and cell phones. Java is widely used for web applications in numerous forms, one of which are Java Applets. There exists a stack buffer overflow vulnerability in Sun Java Web Start. The vulnerability is due to improper bounds checking while handling XML based JNLP files. A remote attacker can exploit this vulnerability by enticing the target user to open a crafted JNLP file, potentially causing arbitrary code to be injected and executed in the security context of the current user. An attack targeting this vulnerability can result in the injection and execution of code. If code execution is successful, the behavior of the target will depend on the intention of the attacker. Any code injected will be executed within the security context of the currently logged in user. In an attack case where code execution is unsuccessful, the application used to open the document will terminate abnormally.
