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 programs that are deployed on personal computers as well as embedded devices and cell phones. Java technology is distributed in the form of various tools such as Java Runtime Environment (JRE) and Java Development Kit (JDK). There exists an integer overflow vulnerability in Sun Java Runtime Environment software. The vulnerability is due to signedness error while parsing certain Type1 font files. A remote attacker can exploit this vulnerability by enticing a target user to open a crafted HTML file. Successful exploitation may lead to arbitrary code execution on the target. In case of an attack case where code injection and execution is successful, the behavior of the target is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the logged in user. In case of an attack case where code injection is not successful, the affected process will terminate abnormally.
