GlobalLink 'GLChat.ocx' ActiveX control is prone to a buffer-overflow vulnerability because it fails to properly bounds-check 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.
|
|
|
|
GlobalLink 'GLChat.ocx' ActiveX control 2.5.1.33 is reported affected by this issue; other versions may also be vulnerable.
