The CoolKey Javacard applet used by the SC650 Smart Card contains an Integer Overflow Error. The vulnerability is persistent in the most recent version currently hosted online at http://svn.fedorahosted.org/svn/coolkey

Specifically, there is an unhandled integer overflow error within the ReadObject() method in the cardedge.java file of the CoolKey package. Two short integer variables 'offset' and 'size' may be considered tainted inputs from the host machine, and specially chosen values of 'offset' and 'size' allow passage through all of the exception handling to allow execution of the sendData() method with an improperly chosen offset.

Have the simple one line fix for the applet compiled.

Completed a gpshell script to test the fix with the old and fixed applet to view the difference in behavior.

Have run the tests on an enrolled card and it works as expect.

Now need a quick review by BobR and a build before the new applet can be checked into TPS.
