A Security Vulnerability in the Java Runtime Environment (JRE) Virtual Machine With Code Generation May Allow Escalation of Privileges

1. Impact

A security vulnerability in the Java Runtime Environment (JRE) Virtual Machine with code generation may allow an untrusted applet to elevate its privileges. For example, an applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet.
