Technical details
A vulnerability exists in the Java Bytecode Verifier component of the Java Runtime Environment. The flaw allows a malicious Java applet to bypass the 'sandbox' security model and execute arbitrary system commands with the privileges of the user running the applet. This is achieved by exploiting weaknesses in how the verifier validates bytecode before execution. While the attack vector is local in terms of execution context, it is typically delivered via a remote web page containing a malicious applet. The vulnerability was originally addressed in early Sun Microsystems security bulletins.
