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 application's support for 3D objects. While parsing the 0xFFFFFF45 RIFF record type, the process performs arithmetic on a size value and uses the result for a heap-based allocation. By specifying a large enough value an attacker can force the integer to wrap and thus the process will under-allocate the buffer. This memory is later copied into using a different size value which results in object corruption that can be leveraged to execute arbitrary code under the context of the user running the browser.
