Synopsis |
16 |
======== |
17 |
|
18 |
Multiple vulnerabilities have been discovered in MadWifi, possibly |
19 |
allowing for the execution of arbitrary code or a Denial of Service. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
The MadWifi driver provides support for Atheros based IEEE 802.11 |
25 |
Wireless Lan cards. |

Description |
36 |
=========== |
37 |
|
38 |
Md Sohail Ahmad from AirTight Networks has discovered a divison by zero |
39 |
in the ath_beacon_config() function (CVE-2007-2830). The vendor has |
40 |
corrected an input validation error in the |
41 |
ieee80211_ioctl_getwmmparams() and ieee80211_ioctl_getwmmparams() |
42 |
functions(CVE-207-2831), and an input sanitization error when parsing |
43 |
nested 802.3 Ethernet frame lengths (CVE-2007-2829). |
44 |
|
45 |
Impact |
46 |
====== |
47 |
|
48 |
An attacker could send specially crafted packets to a vulnerable host |
49 |
to exploit one of these vulnerabilities, possibly resulting in the |
50 |
execution of arbitrary code with root privileges, or a Denial of |
51 |
Service. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
There is no known workaround at this time. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
|
61 |
All MadWifi users should upgrade to the latest version: |
62 |
|
63 |
# emerge --sync |
64 |
# emerge --ask --oneshot --verbose ">=net-wireless/madwifi-ng-0.9.3.1" |
65 |
