Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
MadWifi is vulnerable to a buffer overflow that could potentially lead |
| 19 |
to the remote execution of arbitrary code with root privileges. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
MadWifi (Multiband Atheros Driver for Wireless Fidelity) provides a |
| 25 |
Linux kernel device driver for Atheros-based Wireless LAN devices. |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Laurent Butti, Jerome Raznieski and Julien Tinnes reported a buffer |
| 39 |
overflow in the encode_ie() and the giwscan_cb() functions from |
| 40 |
ieee80211_wireless.c. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker could send specially crafted wireless WPA packets |
| 46 |
containing malicious RSN Information Headers (IE) that could |
| 47 |
potentially lead to the remote execution of arbitrary code as the root |
| 48 |
user. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All MadWifi users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=net-wireless/madwifi-ng-0.9.2.1" |
