Marvell EAPOL-Key Length Overflow

WVE ID: WVE-2008-0009

Type: Vulnerability

Status: Candidate

Classification:
Input Manipulation

Description:
Some versions of the Marvell wireless driver used in access points such as the Netgear WN802T do not correctly validate the EAPOL key fields.

Discussion:
A malicious EAPOL-Key packet with an invalid advertised length can trigger a denial of service or possible code execution. This can only be achieved after a successful 802.11 association exchange.
