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.
A vulnerability in the Hotspot subcomponent of Java Runtime Environment could allow a remote attacker to execute arbitrary code if a user is tricked into opening a web page with a specially crafted applet.
