HTTP: LEADTOOLS Raster Twain LtocxTwainu.dll Buffer Overflow

This signature detects attempts to use unsafe ActiveX controls in the LEADTOOLS Raster Twain LtocxTwainu.dll. An attacker can create a malicious Web site containing Web pages with dangerous ActiveX controls, which if accessed by a victim, allows the attacker to gain control of the victim's client browser.

Extended Description

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.
