It is used by a wide range of open-source projects including Wireshark". Local exploitation of an input validation vulnerability within the NPF.SYS device driver of WinPcap allows attackers to execute arbitrary code in kernel context.   Credit: The information has been provided by Mario Ballano from 48bits.com.

By passing carefully chosen parameters to this IOCTL, an attacker can overwrite arbitrary kernel memory. Analysis: Exploitation allows attackers to execute arbitrary code in kernel context. The vulnerable device driver is loaded when WinPcap is initialized. This driver can be set to load on start-up depending on a choice made at installation time. This is not the default setting. In a default installation, the device driver is not loaded until an Administrator utilizes a WinPcap dependent application. Once they do, it will become accessible to normal users as well. When a program using this driver exists, it is not unloaded. Attackers will continue to have access until the driver is manually unloaded. If the option to allow normal user access was chosen at installation time, attackers will always have access to this device driver. Consequently, a local attacker without administrator privileges would have access to sniff, as well as exploit this vulnerability. Vendor response: The WinPcap Team has addressed this vulnerability by releasing version 4.0.1 of the WinPcap software.
