Vigil@nce: NDISWrapper, buffer overflows
November 2008 by Vigil@nce
A WiFi attacker can create several overflows in NDISWrapper in order to execute code on the system.
Consequences: administrator access/rights
Provenance: radio connection
Means of attack: no proof of concept, no attack
Ability of attacker: expert (4/4)
Confidence: confirmed by the editor (5/5)
Diffusion of the vulnerable configuration: high (3/3)
Creation date: 07/11/2008
The NDISWrapper tool is used to install Windows network drivers on Linux.
When NDISWrapper is used with a WiFi card, it copies the ESSID (the network name) in arrays of fixed size with the memcpy() or sprintf() functions. A buffer overflow thus occurs.
An attacker can therefore send a long ESSID via the WiFi network in order to execute code in the Linux kernel.
Identifiers: CVE-2008-4395, VIGILANCE-VUL-8229
