Description
The UltraHVCam ActiveX Control 'UltraHVCamX.ocx' suffers from a stack buffer overflow vulnerability when parsing large amount of bytes to several functions in UltraHVCamLib, resulting in memory corruption overwriting several registers including the SEH. An attacker can gain access to the system of the affected node and execute arbitrary code.
(4b24.478c): Access violation - code c0000005 (first chance)
