### Background
Java is a programming language that compiles programs to bytecode, which is then executed inside a Java Virtual Machine. This is optimal for applications that must run on various hardware platforms, such as web applets.
### Problem
Java 6 Update 23 and before are vulnerable to an unsigned code execution vulnerability. This may allow an attacker to trick a user into viewing a website with a malicious embedded Java applet.
### Resolution
Upgrade to [Oracle JRE 6 Update 25](<http://www.oracle.com/technetwork/java/javase/downloads/index.html>) or later.
