Zero-Day Vulnerability in Microsoft Word

Microsoft recently published a security advisory about a zero-day vulnerability affecting Microsoft Word. (A zero-day vulnerability is one that exploits a previously unknown vulnerability and for which a patch has not yet been released.) The vulnerability can allow an attacker to execute code on your system if you open a specially crafted document containing rich text format (RTF) content in an affected version of Microsoft Word.

Microsoft has released a temporary Fix It solution, which will prevent Word from opening RTF content. For more information about the Fix It solution, visit Microsoft’s support site at
