DESCRIPTION:
Laurent Butti has reported a vulnerability in NetGear MA521 Wireless
driver, which can be exploited by malicious people to compromise a
vulnerable system.

The vulnerability is caused due to an error in the MA521nd5.SYS
device driver when handling beacon or probe response frames
containing an invalid supported rates information element. This can
be exploited to cause a memory corruption via a specially crafted
packet when the driver is running in active scanning mode.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in version 5.148.724.2003. Other
versions may also be affected.
