Laurent Butti has reported a vulnerability in the D-Link DWL-G650+ wireless driver, which can be exploited by malicious people to cause a DoS (Denial of Service) or to potentially compromise a vulnerable system.
The vulnerability is caused due to an error within the handling of beacon frames containing an overly long TIM information element and can be exploited to cause a buffer overflow via a specially crafted packet.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is reported in version 126.96.36.199 (Rev. A1). Other versions may also be affected.
Solution: Turn off the wireless card when not in use.
