'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.
