DVRHOST PDVRATL.DLL ActiveX Control Heap Based Buffer Overflow Vulnerability

The DVRHOST 'PdvrAtl.PdvrOcx.1' ActiveX control is prone to a heap-based buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied data.

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.
