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 way Adobe Flash player handles calls to the _global.ASconstructor function. If this function is called with id '2200' it will write a 0x01 byte to a user supplied address. This memory corruption can result in remote code execution under the context of the current user.
