Intel 2100 PRO/Wireless Network Connection Hardware

The Intel 2100 Pro mini-PCI WiFi adapter is an 802.11b WLAN card.

The Problem
From INTEL-SA-00005:
A security vulnerability exists in the Microsoft Windows drivers for the Intel 2100 PRO/Wireless Network Connection Hardware because of the way that driver handles certain requests by applications. The vulnerability could potentially be exploited by injecting specially crafted malicious frames into the driver and with the aid of an application loaded on the local system kernel level privileges could potentially be obtained.

An attacker may be able to execute arbitrary code with kernel-level privileges.

Upgrade Intel drivers

Intel has released updates to address this issue. The Intel support site also provides a tool to assist users in determining the model and version of the wireless adapter they are using.

Users are encouraged to consult their OEM and hardware providers to determine the best way to update drivers. From Intel:
It is recommended that you obtain and use the software provided via your laptop manufacturer.
