Alps Pointing-Device Driver
An issue in the Alps Pointing-device Driver allows the current user to map and write to the `ApMsgFwd File Mapping Object` section. The `ApMsgFwd.exe` uses the data written to this section as arguments to functions, which can cause a denial of service condition when invalid pointers are written to the mapped section. This driver has been used with various devices, including Dell, ThinkPad, and VAIO.
