Atheros Wireless drivers management frames denial of service
| atheros-management-frames-dos (35788) |  Medium Risk |
Description:
Atheros Wireless drivers are vulnerable to a denial of service, caused by a buffer overflow when handling malformed management frames. By sending a specially-crafted 802.11 management frame to a vulnerable adapter, a remote attacker could exploit this vulnerability to overflow a buffer and cause the system to crash, if the attacker is in range of the affected device.
Note: Successful exploitation of this vulnerability on a Unix system requires the use of an NDISWrapper or similar technology for loading the driver.
