Adobe Flash Player loadPCMFromByteArray Remote Code Execution Vulnerability
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Flash 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 loadPCMFromByteArray function in the flash.media.Sound object. When this function is called with a high number of 'samples' an integer overflow occurs during the calculation of a buffer size. This can lead to memory corruption that can result in remote code execution under the context of the current user.
