Microsoft Office excel with another security problem

Once again for the third time microsoft office excel is hit with another security problem which is getting bill gates all mad!
This is what it does:
"A successful attack may allow attackers to access sensitive information and potentially execute malicious commands on a vulnerable computer," Symantec said in the alert, which was sent to users of its DeepSight security intelligence. The vulnerability was reported by researcher Debasis Mohanty.
The issue relates to the ability to load ActiveX controls in an Office document and is not a vulnerability but an Office feature, a Microsoft representative said. "This behavior is by design and by itself does not represent a security risk to customers," he said. An ActiveX control is a small application typically used to make Web sites more interactive

I really wonder y hackers do this and u think it is a start to world domination to those hackers?
