This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Flash. 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 handling of BitmapData objects. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated object. An attacker can leverage this vulnerability to execute code under the context of the current process.
