The Apple Airport driver provided with Orinoco-based Airport cards (1999-2003 PowerBooks, iMacs) is vulnerable to a remote memory corruption flaw. When the driver is placed into active scanning mode, a malformed probe response frame can be used to corrupt internal kernel structures, leading to arbitrary code execution. This vulnerability is triggered when a probe response frame is received that does not contain valid information element (IE) fields after the fixed-length header. The data following the fixed-length header is copied over internal kernel structures, resulting in memory operations being performed on attacker-controlled pointer values. This is the Metasploit module for this vulnerability.
