Vulnerable Systems:
* Adobe Shockwave Player
User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the Cursor Asset.x32 module responsible for parsing cursor structures from within Director movie files (.dir). While handling a size element, the code performs an unchecked multiplication operation which can cause an integer to wrap. This results in an undersized heap allocation which can be overflowed with user data leading to arbitrary code execution under the context of the user running the browser.
