Marvell Driver Multiple Information Element Overflows

Summary:
--------
* The wireless drivers in some Wi-Fi access points (such as the
MARVELL-based Linksys WAP4400N) do not correctly parse information
elements included in association requests. Most information elements are
used by the wireless access point and clients to advertise their
capabilities (regarding rates, network name, cryptographic capabilities...).

Assigned CVE:
-------------
* CVE-2007-5475

Details:
--------
* The bug can be triggered by a malicious association request to the
wireless access point (the information element could be a rates,
extended rates, or any supported information element that will be parsed
by the flawed parser, the information element uses an inappropriate
length, typically too long). This can be achieved only after a
successful 802.11 authentication (in "Open" or "Shared" mode according
to the configuration of the wireless access point).

Attack Impact:
--------------
* Denial-of-service (reboot or hang-up) and possibly remote arbitrary
code execution

Attack Vector:
--------------
* Unauthenticated wireless device

Timeline:
---------
* 2007-10-22 - Vulnerability reported to Linksys
* 2007-10-23 - Full details sent to Linksys
* 2009-09-10 - Cisco/Linksys released a patched firmware (1.2.19)
* 2009-11-10 - Release of this security advisory

Affected Products:
------------------
* Linksys WAP4400N (firmware 1.2.17) with MARVELL 88W8361P-BEM1 chipset

Vulnerable Devices:
-------------------
* As it is a wireless driver specific issue, the wireless vendor should
use the latest chipset wireless driver for their access point firmwares.
This security vulnerability was originally reported to Linksys, updated
firmwares should be available on Cisco/Linksys web site. Any other
wireless device relying on this vulnerable wireless driver is likely to
be vulnerable.

Atheros Driver Reserved Frame Vulnerability

Summary:
--------
* The wireless driver in some Wi-Fi access points (such as the
ATHEROS-based Netgear WNDAP330) do not correctly parse malformed
reserved management frames.

Assigned CVE:
-------------
* CVE-2009-0052

Details:
--------
* The bug can be triggered by a malicious reserved management frame sent
to the wireless access point (truncated packet). This can be achieved
only after a successful 802.11 authentication (in "Open" mode according
to the configuration of the wireless access point) and a successful
802.11 association with appropriate security parameters (e.g. WPA w/
TKIP unicast, TKIP multicast) which depends on the configuration of the
wireless access point.

Attack Impact:
--------------
* Denial-of-service (reboot or hang-up) and possibly remote arbitrary
code execution

Attack Vector:
--------------
* Unauthenticated wireless device for WPA/WPA2-PSK and EAP-based
authenticated wireless device for WPA/WPA2-EAP

Timeline:
---------
* 2008-09-30 - Vulnerability reported Netgear
* 2008-10-02 - PoC sent to Netgear
* 2009-10-14 - Netgear released a patched firmware (3.0.3)
* 2009-11-10 - Release of this security advisory

Affected Products:
------------------
* Netgear WNDAP330 (firmware 2.1.11) with ATHEROS AR9160-BC1A chipset

Vulnerable Devices:
-------------------
* As it is a wireless driver specific issue, the wireless vendor should
use the latest chipset wireless driver for their access point firmwares.
This security vulnerability was reported to Netgear, updated firmwares
should be available on their web site. Any other wireless device relying
on this vulnerable wireless driver is likely to be vulnerable.

School

Well I thought I was done with school for a while but I guess I can't get enough so here we go again. Wish me luck doesn't look like it is going to be as easy as I thought. http://www.aiuonline.edu/online-computer-forensics-degree/

Windows 7

  Finally waiting for my first valid copy of Windows 7 through the student offer. Just enrolled in Data Forensics at the University of Colorado so I should qualify. If so I am going to grab the Office 2007 as well. I do have a copy running on my vm-ware machine for testing my software and auditing but it was one with my action pack.
  Anyway I also had a chance to install Ubuntu 9.10 on my laptop. I must say I am really impressed with the smooth install and ease of use. It went on my Thinkpad Z61p the only issue it has is the video drivers for the ATI mobile video card. It even installed my Sprint EVDO card and created a connection for it. Really can't wait for the dev's to get the next version out they improve it so much with each release.
