Hello,

This is an issue where an Office document is used to affect the computer that is it opened on. The attacker is able to gain the same rights as the user that opened it. So, yes, this is something everyone should be aware of. The following link is a fix for the issue, but does not work on Windows 8 and 8.1 64-bit versions with 64-bit versions of PowerPoint. https://support.microsoft.com/kb/3010060
