Details:
========
A Buffer Overflow vulnerability is detected on the UPEK Protector Suite QL v5.x & version 2011 in combination with 
the EikonTouch USB peripheral. The vulnerability allows an local attacker to crash the EikonTouch USB peripheral device 
driver/software via local buffer overflow. The bug is located on the profile import module of the software when 
processing 
special crafted (manipualted) .vtp profile files.

Vulnerable Module(s): 
                                                                [+] .VTP FILE - USERNAME


Note: After the software crash the driver device of the fingerprinter crashs too. All control center functions are 
stable unavailable.

Proof of Concept:
=================
This vulnerability can be exploited by local attacker. For demonstration or reproduce ...

Review:  *.vtp

Solution:
=========
Restrict the username to maximum to prevent against buffer overflows when processing large -username .vtp files.


Risk:
=====
The security risk of the local buffer overflow vulnerability is estimated as high(-).
