Hewlett Packard HPQVWOCX.DLL ActiveX Control Stack Based Buffer Overflow Vulnerability

Hewlett Packard 'hpqvwocx.dll' ActiveX control library is prone to a stack-based buffer-overflow vulnerability because it fails to properly check boundaries on user-supplied data before copying it into an insufficiently sized memory 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.

This issue affects 'hpqvwocx' 1.0.0.309; other versions may also be affected.
