Apple Mac OS X kextload is prone to a buffer-overflow vulnerability because it fails to sufficiently bounds-check user-supplied data before copying it to a finite-sized memory buffer.
|
|
|
|
This issue is not exploitable by itself, because kextload is not installed as a setuid-superuser application by default. To exploit this issue, an attacker must use another program running with elevated privileges to directly manipulate the arguments passed to kextload.
|
|
|
|
An attacker can exploit this issue to execute arbitrary machine code with superuser privileges. A successful exploit may result in the complete compromise of the affect computer.
|
|
|
|
Example kextload buffer-overflow vulnerability affecting TDIXsupport:
|
|
|
|
netragard-test:$ sudo ktrace -di ./TDIXSupport `perl -e 'print "A" x 1000'`/TDIXController.kext
