The bug was discovered 05/09/2017. The weakness was presented 05/09/2017 with FireEye, Inc. as 3114375 as confirmed security update guide (Website). The advisory is shared at portal.msrc.microsoft.com. This vulnerability is uniquely identified as CVE-2017-0261 since 09/09/2016. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details are unknown but an exploit is available. The advisory points out:

A remote code execution vulnerability exists in Microsoft Office that could be exploited when a user opens a file containing a malformed graphics image or when a user inserts a malformed graphics image into an Office file. Such a file could also be included in an email attachment. An attacker could exploit the vulnerability by constructing a specially crafted EPS file that could allow remote code execution. An attacker who successfully exploited this vulnerability could take control of the affected system. This vulnerability could not be exploited automatically through a Web-based attack scenario. An attacker could host a specially crafted website containing an Office file that is designed to exploit the vulnerability, and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements by adding specially crafted content that could exploit the vulnerability. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an instant messenger or email message that takes users to the attacker's website, or by getting them to open an attachment sent through email.
