Discussion
LEADTOOLS Imaging ActiveX 'LtocxTwainu.dll' Buffer Overflow Vulnerability
The LEADTOOLS Imaging ActiveX control is prone to a buffer-overflow vulnerability because the application fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer.
Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Failed exploit attempts likely result in denial-of-service conditions.
LEADTOOLS Imaging ActiveX control 16.5 is vulnerable to this issue; other versions may also be affected.
