Comment 8 Marc Schoenefeld 2011-01-18 15:25:12 UTC
It was discovered that the JNLPSecurityManager in certain cases failed to properly implement the security policy, and did not throw an exception to prevent completion of a possibly unsafe or sensitive operation and simply returned from the checkPermission method. 

Any service relying on the SecurityManager.checkPermission() method to throw an exception then incorrectly assumed that the permission was granted.

The issue was independently reported by Omair Majid for JNLP applications, and for applets by a reporter cooperating with the TippingPoint Zero Day Initiave.
