It was discovered that the LambdaFormEditor class in the Libraries component of OpenJDK did not correctly perform bounds checks in the permuteArgumentsForm() function. An untrusted Java application or applet could use this flaw to corrupt JVM memory and cause it to crash or, possibly, execute arbitrary code, bypassing Java sandbox restrictions. The problem is triggered when using MethodHandle.permuteArguments().
