NetGear wireless driver fails to properly process certain 802.11 management frames

Vulnerability Note VU#445753

Original Release Date: 2006-11-17 | Last Revised: 2006-11-17

Overview

A buffer overflow vulnerability has been reported in the Netgear WG111v2.SYS wireless driver. Successful exploitation of this vulnerability may allow an attacker to execute arbitrary code, or cause a denial-of-service condition.

Description

The WG111v2.SYS driver is a wireless (802.11) device driver produced by Netgear.

A stack buffer overflow vulnerability has been reported in the WG111v2.SYS driver. An attacker may be able to trigger the overflow by sending a malformed beacon request frame to a vulnerable system. Since 802.11b and 802.11g management frames are not encrypted, using wireless encryption (WEP/WPA) does not mitigate this vulnerability.

Note that Linux or Unix systems that use NDISWrapper or similar technologies to load the WG111v2.SYS driver may also be vulnerable.

Impact

A remote, unauthenticated attacker may be able to execute arbitrary code, or cause a denial-of-service condition on a vulnerable system.

Solution

We are currently unaware of a practical solution to this problem.

Disable wireless adapters

Disabling wireless adapters may reduce the chances of this vulnerability being exploited.
