Multiple Consona Products 'SdcUser.TgConCtl' ActiveX Control Buffer Overflow Vulnerability

An ActiveX control included with multiple Consona (formerly SupportSoft) products is prone to a buffer-overflow vulnerability because the control fails to perform adequate boundary checks on user-supplied data.

Successful exploits allow remote attackers to execute arbitrary code in the context of the application, typically Internet Explorer, using the ActiveX control. Failed exploit attempts will likely result in denial-of-service conditions.

The following are vulnerable:
Consona Live Assistance
Consona Dynamic Agent
Consona Subscriber Assistance
