Description:
eEye Digital Security has reported a vulnerability in Intel LAN drivers, which can be exploited by malicious, local users to gain escalated privileges.

A boundary error in OID handler 0xFF0203FC when making IOCTL_NDIS_QUERY_SELECTED_STATS (0x17000E) query requests to "\Device\{adapterguid}" can be exploited to cause a stack-based buffer overflow via a an overly long string (longer than 370 bytes) passed to the said OID handler.

Successful exploitation allows execution of arbitrary code with kernel privileges.

Solution:
Apply patches.
