To all Mac users who are using Microsoft Word that came with Microsoft Office v.X and Microsoft Office 2004.
A "zero-day vulnerability" had been found by the security advisories in all versions of Microsoft Office v.X and Microsoft Office 2004.
Microsoft themselves had also issued a Security Advisory for this vulnerability.
The current solution is not to open or save any MS Word documents from untrusted users.
My personal advise to all my Macintosh friends is not to use MS Word at all. This is because MS Word documents from trusted users may be unknowingly passing you a malformed MS Word document that is designed to take advantage of this vulnerability in MS Word.
The bottom line... I try not to use any Microsoft products whenever I can. As of now, close to 5 years now I had yet to use any Microsoft software on my Mac accept for testing purposes.
