|
||
|
|
This module abuses an Invalid Array Indexing Vulnerability on the
|
||
|
|
IntegerInterleavedRaster.verify() function in order to produce a
|
||
|
|
memory corruption and finally escape the Java Sandbox. The vulnerability
|
||
|
|
affects Java version 7u21 and earlier. The module, which doesn't bypass
|
||
|
|
click2play, has been tested successfully on Java 7u21 on Windows and
|
||
|
|
Linux systems.
