Vulnerability details
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to stack-based buffer overflow in CEditView::ExecCmd when processing a crafted WSH macro or overly long command string. A remote attacker can trick the victim into executing a crafted .js or .vbs macro file to cause a denial of service.
