LEADTOOLS ActiveX Common Dialogs 16.5 Multiple Remote Vulnerabilities
 
Vendor: LEAD Technologies, Inc.
Product Web Page: http://www.leadtools.com
Affected version: 16.5.0.2
 
Summary: With LEADTOOLS you can control any scanner, digital camera
or capture card that has a TWAIN (32 and 64 bit) device driver.
High-level acquisition support is included for ease of use while
low-level functionality is provided for flexibility and control in
even the most demanding scanning applications.
 
Desc: LEADTOOLS ActiveX Common Dialogs suffers from multiple remote
vulnerabilities (IoF, BoF, DoS) as it fails to sanitize the input in
different objects included in the Common Dialogs class.
