HTTP LeadTools Raster ActiveX BO

Severity: High

This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.


This signature detects attempt to exploit a buffer overflow vulnerability by passing long arguments into a property of LeadTools Raster Document Object Library ActiveX control.

Additional Information

LEADTOOLS Raster OCR Document Object Library ActiveX control is prone to a buffer-overflow vulnerability because it fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer.

This issue occurs when an excessive amount of data is passed to the 'DictionaryFileName' property of the 'LTRDC14E.DLL' ActiveX control.

This issue resides in the ActiveX control with CLSID: {00140B30-B1BA-11CE-ABC6-F5B2E79D9E3F}.

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 Raster OCR Document Object Library ActiveX control is vulnerable to this issue; other versions may also be affected.
