Title: ====== Upek Protector Suite QL 2011 - Buffer Overflow Vulnerability
Date: ===== 2011-09-26 References: =========== http://www.vulnerability-lab.com/get_content.php?id=259 VL-ID: ===== 259 Abstract: ========= The Vulnerability Lab Research Team discovered a Buffer Overflow Vulnerability on the UPEK Protector Suite QL in combination with the eikon fingerprint scanner device. Report-Timeline: ================ 2011-04-03: Vendor Notification 2011-04-19: Vendor Notification 2011-**-**: Vendor Response/Feedback 2011-**-**: Vendor Fix/Patch 2011-09-24: Public or Non-Public Disclosure Status: ======== Published Affected Products: ================== Upek Protector Suite QL 2011 Upek Protector Suite QL 5.x Exploitation-Technique: ======================= Local Severity: ========= High 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.
